  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The configurations shown in the following embodiments are merely examples, and the present invention is not limited to the illustrated configurations.

  In addition, an adjustment command (hereinafter may be referred to as a command) in the following embodiments is determined based on, for example, an Open Network Video Interface Forum (hereinafter also referred to as ONVIF) standard. In the ONVIF standard, for example, this command is defined by using the XML Schema Definition language (hereinafter sometimes referred to as XSD).

Example 1
The network configuration according to this embodiment will be described below with reference to FIG. More specifically, FIG. 1 is a diagram illustrating an example of a system configuration of the monitoring system according to the present embodiment.

  In the monitoring system according to the present embodiment, the imaging apparatus 1000 and the client apparatus 2000 are connected via the IP network 1500 (in a state where they can communicate with each other). Accordingly, the imaging apparatus 1000 can distribute the captured image to the client apparatus 2000 via the IP network 1500.

  Note that the imaging apparatus 1000 in this embodiment is a monitoring camera that captures a moving image, and more specifically, a network camera used for monitoring.

  The client device 2000 in this embodiment is an example of an external device such as a PC. Further, the monitoring system in the present embodiment corresponds to an imaging system.

  The IP network 1500 is assumed to be composed of a plurality of routers, switches, cables, and the like that satisfy a communication standard such as Ethernet (registered trademark). However, in this embodiment, any communication standard, scale, and configuration may be used as long as communication between the imaging device 1000 and the client device 2000 can be performed.

  For example, the IP network 1500 may be configured by the Internet, a wired LAN (Local Area Network), a wireless LAN (Wireless LAN), a WAN (Wide Area Network), or the like. Note that the imaging apparatus 1000 according to the present embodiment may be compatible with, for example, PoE (Power Over Ethernet (registered trademark)), and may be supplied with power via a LAN cable.

  The client device 2000 transmits commands that are various adjustment commands to the imaging device 1000. These commands are, for example, a command for changing the imaging direction and angle of view of the imaging apparatus 1000, a command for changing imaging parameters, a command for starting streaming of the captured image, and the like.

  On the other hand, the imaging apparatus 1000 transmits a response including setting information for these commands and a stream of captured images to the client apparatus 2000. Further, the imaging apparatus 1000 changes the angle of view in accordance with a command for changing the angle of view received from the client apparatus 2000.

  Next, FIG. 2 is a diagram illustrating an example of a hardware configuration of the imaging apparatus 1000 according to the present embodiment. The imaging optical system 2 in FIG. 2 forms an image of a subject imaged by the imaging device 1000 on the imaging element 6 via the optical filter 4.

  Here, in this embodiment, the optical filter 4 is an infrared cut filter (Infrared Cut Filter; hereinafter referred to as IRCF). Based on the drive signal from the optical filter drive circuit 24, the optical path between the image pickup optical system 2 and the image pickup element 6 is inserted and removed by a drive mechanism (not shown) such as a plunger using an electromagnet. . Here, blocking infrared rays means that infrared rays are greatly attenuated, and does not have to block 100%.

  The image sensor 6 is composed of a CCD image sensor, a CMOS image sensor, or the like. The imaging element 6 captures an image of the subject formed by the imaging optical system 2. Furthermore, the image sensor 6 outputs a captured image by photoelectrically converting the captured subject image.

  Note that the image pickup device 6 in this embodiment corresponds to an image pickup unit that picks up an image of a subject formed by the image pickup optical system 2.

  The video signal processing circuit 8 follows instructions from a central processing circuit (hereinafter also referred to as CPU) 26 described later. Specifically, only the luminance signal of the captured image output from the image sensor 6 or both the luminance signal and the color difference signal of the captured image output from the image sensor 6 are output to the encoding circuit 10.

  In addition, the video signal processing circuit 8 outputs the luminance signal of the captured image output from the image sensor 6 to the luminance measurement circuit 18 in accordance with an instruction from the CPU 26.

  When only the luminance signal is output from the video signal processing circuit 8, the encoding circuit 10 compresses and encodes the output luminance signal, and outputs the compressed and encoded luminance signal to the buffer 12 as a captured image. On the other hand, when the luminance signal and the color difference signal are output from the video signal processing circuit 8, the encoding circuit 10 compresses and encodes the output luminance signal and the color difference signal, and the compressed luminance signal and the color difference signal are encoded. Is output to the buffer 12 as a captured image.

  The buffer 12 buffers the captured image output from the encoding circuit 10. Then, the buffer 12 outputs the buffered captured image to a communication circuit (hereinafter sometimes referred to as I / F) 14. The I / F 14 packetizes the captured image output from the buffer 12 and transmits the packetized captured image to the client apparatus 2000 via the communication terminal 16. Here, the communication terminal 16 includes a LAN terminal to which a LAN cable is connected.

  The I / F 14 corresponds to a receiving unit that receives a command related to insertion / removal of the optical filter 4 from the external client device 2000.

  The luminance measurement circuit 18 measures the luminance value of the current subject of the imaging apparatus 1000 based on the luminance signal output from the video signal processing circuit 8. Then, the luminance measurement circuit 18 outputs the measured luminance value to the determination circuit 20. The determination circuit 20 compares the luminance value of the subject output from the luminance measurement circuit 18 with the threshold value of the luminance of the subject set by the CPU 26, and outputs the comparison result to the CPU 26.

  The timer circuit 22 is set with a delay time from the CPU 26. In addition, the timer circuit 22 counts the time elapsed after receiving this instruction in accordance with the instruction to start timing from the CPU 26. Then, when the set delay time has elapsed, the time measuring circuit 22 outputs a signal indicating that the delay time has elapsed to the CPU 26.

  The optical filter drive circuit 24 receives an instruction from the CPU 26 and removes the optical filter 4 from the optical path of the imaging optical system 2. Further, the optical filter driving circuit 24 receives an instruction from the CPU 26 and inserts the optical filter 4 into the optical path of the imaging optical system 2. The optical filter drive circuit 24 in this embodiment corresponds to an insertion / removal unit that inserts / removes the optical filter 4 with respect to the optical path of the imaging optical system 2.

  The CPU 26 comprehensively controls each component of the imaging device 1000. Further, the CPU 26 executes a program stored in a non-volatile memory (Electrically Erasable Programmable Read Only Memory; hereinafter referred to as EEPROM) 28 that can electrically erase data.

  The EEPROM 28 can store parameters for operating the imaging apparatus 1000, commands received from the client apparatus 2000, and the like. Alternatively, the CPU 26 may perform control using hardware. The CPU 26 in this embodiment corresponds to a control unit that controls the optical filter driving circuit 24 that inserts and removes the optical filter 4.

  In this embodiment, IRCF is used as the optical filter 4, but the present invention is not limited to this. For example, as the optical filter 4, an ND filter that reduces the amount of incident light, a beam splitter that changes the destination of transmitted light, a filter that transmits only light of a specific wavelength, a polarization filter that transmits only a specific polarization component, etc. Different optical filters may be used.

  Next, FIG. 3 is a flowchart for explaining processing executed by the CPU 26 when an instruction command for instructing insertion or removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 is received by the I / F 14. It is.

  In step S301, the CPU 26 determines whether an instruction command that has been subjected to appropriate packet processing by the I / F 14 has been received. If the instruction command is received, the CPU 26 proceeds to step S302. If not received, the CPU 26 returns the process to step S301.

  In step S <b> 302, the CPU 26 analyzes what kind of command the input insertion instruction command (command received by the I / F 14) is.

  In step S303, the CPU 26 determines whether the command is an insertion command based on the result analyzed in step S302. If the CPU 26 determines that the command is an insertion command, the process proceeds to step S304. On the other hand, if the CPU 26 determines that the command is not an insertion command, the process proceeds to step S305.

  In step S <b> 304, the CPU 26 controls the optical filter driving circuit 24 to insert the optical filter 4 in the optical path of the imaging optical system 2.

  Here, in the present embodiment, imaging of the subject by the imaging apparatus 1000 with the optical filter 4 inserted in the optical path of the imaging optical system 2 is referred to as visible light imaging (normal imaging). That is, in visible light imaging, the imaging apparatus 1000 captures an image of the subject in a state where light from the subject is incident on the image sensor 6 via the optical filter 4.

  When visible light imaging is performed by the imaging apparatus 1000, the CPU 26 places importance on the color reproducibility of the captured image output from the imaging device 6 and instructs the video signal processing circuit 8 to output the luminance signal and the color difference signal. Is output to the encoding circuit 10. As a result, the I / F 14 delivers a color captured image. Therefore, in this embodiment, when visible light imaging is performed by the imaging apparatus 1000, the imaging mode of the imaging apparatus 1000 may be referred to as a color mode.

  In step S305, if the CPU 26 determines that the command is not an insertion command in step S303, the CPU 26 determines whether the command is a removal command based on the result analyzed in step S302. If the CPU 26 determines that the command is a removal command, the process proceeds to step S306. On the other hand, if the CPU 26 determines that the command is not an extraction command, the process proceeds to step S307.

  In step S <b> 306, the CPU 26 controls the optical filter driving circuit 24 to remove the optical filter 4 from the optical path of the imaging optical system 2.

  Here, in the present embodiment, imaging the subject with the imaging apparatus 1000 with the optical filter 4 removed from the optical path of the imaging optical system 2 is referred to as infrared imaging. That is, in infrared imaging, the imaging apparatus 1000 captures an image of the subject in a state where light from the subject is incident on the imaging element 6 without passing through the optical filter 4.

  When infrared imaging is performed by the imaging apparatus 1000, the CPU 26 instructs the video signal processing circuit 8 because the color balance of the captured image output from the imaging device 6 is lost, and encodes only the luminance signal. 10 to output. As a result, the I / F 14 delivers a monochrome captured image. Therefore, in the present embodiment, when infrared imaging is performed by the imaging apparatus 1000, the imaging mode of the imaging apparatus 1000 may be referred to as a monochrome mode.

  In step S307, if the CPU 26 determines that the command is not an extraction command in step S305, the CPU 26 determines whether or not a parameter indicating a luminance threshold is included in the automatic insertion / removal command based on the result analyzed in step S302. Here, the automatic insertion / removal command can describe an adjustment value related to insertion / removal of the optical filter 4.

  This adjustment value can be omitted. The adjustment value is, for example, a parameter indicating a luminance threshold or a parameter indicating a delay time.

  If the CPU 26 determines that it is included, the CPU 26 proceeds to step S308 to set a luminance threshold value corresponding to the parameter included in the command in the determination circuit 20.

  On the other hand, if the CPU 26 determines that it is not included, the CPU 26 advances the processing to step S 309, reads out the luminance threshold value from the parameters stored in advance in the EEPROM 28, and sets it in the determination circuit 20.

  In step S310, the CPU 26 determines whether or not the command includes a parameter indicating the delay time based on the result analyzed in step S302. If it is determined that the CPU 26 includes the CPU 26, the process proceeds to step S <b> 311, and the delay time corresponding to the parameter included in the command is set in the timer circuit 22.

  On the other hand, if the CPU 26 determines that it is not included, the CPU 26 advances the process to step S 312, reads the delay time from the parameters stored in advance in the EEPROM 28, and sets the delay time in the timer circuit 22.

  In step S313, the CPU 26 determines whether or not the optical filter 4 is located outside the optical path. If the CPU 26 determines that the object is out of the optical path, the process proceeds to step S314. On the other hand, if the CPU 26 determines that it is in the optical path, the process proceeds to step S315.

  In step S314, when the CPU 26 determines that the optical filter 4 is out of the optical path in step S313, the determination circuit 20 determines whether or not the luminance of the current subject exceeds the luminance threshold set by the CPU 26. . If the CPU 26 determines that the number is higher, the process proceeds to step S316. On the other hand, if the CPU 26 determines not to exceed, the process returns to step S313.

  In step S316, the CPU 26 instructs the timing circuit 22 to start timing, and proceeds to step S318.

  In step S318, the CPU 26 determines whether or not the current luminance of the subject exceeds the luminance threshold set by the CPU 26 by the determination circuit 20 before the signal indicating that the delay time has elapsed is input from the timer circuit 22. Determine. If the CPU 26 determines that the number is higher, the process proceeds to step S320. On the other hand, if the CPU 26 determines not to exceed, the process returns to step S313.

  In step S320, the CPU 26 determines whether or not a signal indicating that the delay time has elapsed is input from the timer circuit 22. When the signal is input, the CPU 26 advances the process to step S322. On the other hand, if the CPU 26 determines that it has not elapsed, it returns the process to step S313.

  In step S322, the optical filter drive circuit 24 is instructed to insert the optical filter 4 into the optical path of the imaging optical system 2.

  On the other hand, in step S315, if the CPU 26 determines in step S313 that the optical filter 4 is in the optical path, the determination circuit 20 determines whether the current luminance of the subject is below the luminance threshold set by the CPU 26. Determine. If the CPU 26 determines that the number is below, the process proceeds to step S317. On the other hand, if the CPU 26 determines that it is not lower, the process returns to step S313.

  In step S317, the CPU 26 instructs the timing circuit 22 to start timing, and proceeds to step S319.

  In step S319, the CPU 26 determines whether or not the current luminance of the subject is below the luminance threshold set by the CPU 26 by the determination circuit 20 before the signal indicating that the delay time has elapsed is input from the timer circuit 22. Determine. When it is determined that the CPU 26 is below the CPU 26, the process proceeds to step S321. On the other hand, if the CPU 26 determines that it is not lower, the process returns to step S313.

  In step S <b> 321, the CPU 26 determines whether or not a signal indicating that the delay time has elapsed is input from the timer circuit 22. When the signal is input, the CPU 26 advances the process to step S323. On the other hand, if the CPU 26 determines that it has not elapsed, it returns the process to step S313.

  In step S323, the optical filter drive circuit 24 is instructed to remove the optical filter 4 from the optical path of the imaging optical system 2.

  Next, FIG. 4 is a diagram illustrating an example of a hardware configuration of the client apparatus 2000 according to the present embodiment. The client device 2000 in this embodiment is an external device and is configured as a computer device connected to the IP network 1500, and is typically a personal computer (hereinafter sometimes referred to as a PC). It is a general purpose computer.

  The CPU 426 in FIG. 4 controls each component of the client device 2000 in an integrated manner. The CPU 426 executes a program stored in an EEPROM 428 described later. Alternatively, the CPU 426 may perform control using hardware. The EEPROM 428 is used as a program storage area executed by the CPU 426, a work area during program execution, and a data storage area.

  A digital interface unit (hereinafter also referred to as I / F) 414 receives an instruction from the CPU 426 and transmits a command or the like to the imaging apparatus 1000 via the communication terminal 416. Also, the I / F 414 receives a command response, a captured image that has been streamed, and the like from the imaging apparatus 1000 via the communication terminal 416. The communication terminal 416 includes a LAN terminal to which a LAN cable is connected.

  The input unit 408 includes, for example, a button, a cross key, a touch panel, a mouse, and the like. The input unit 408 accepts input of instructions from the user. For example, the input unit 408 can accept input of various command transmission instructions to the imaging apparatus 1000 as instructions from the user.

  In addition, when a command transmission instruction to the imaging apparatus 1000 is input from the user, the input unit 408 notifies the CPU 426 that the input has been made. Then, the CPU 426 generates a command for the imaging apparatus 1000 according to the instruction input to the input unit 408. Next, the CPU 426 instructs the digital interface unit (hereinafter sometimes referred to as I / F) 414 to transmit the generated command to the imaging apparatus 1000.

  Furthermore, the input unit 408 can accept an input of a user response to an inquiry message to the user generated by the CPU 426 executing a program stored in the EEPROM 428.

  Here, the CPU 426 decodes and expands the captured image output from the I / F 414. Then, the CPU 426 outputs the decoded and expanded captured image to the display unit 422. Thereby, the display unit 422 displays an image corresponding to the captured image output from the CPU 426. As the display portion 422 in this embodiment, a liquid crystal display device, a plasma display display device, a cathode ray tube (hereinafter sometimes referred to as CRT) display device such as a cathode ray tube, or the like can be used.

  As described above, the internal configurations of the imaging apparatus 1000 and the client apparatus 2000 have been described. The processing blocks illustrated in FIGS. 2 and 4 are for describing preferred embodiments of the imaging apparatus and the external apparatus according to the present invention. This is not the case. Various modifications and changes can be made within the scope of the present invention, such as including an audio input unit and an audio output unit. Further, as the optical filter 4, not only an optical filter but also different optical filter types such as an ND filter or a combination thereof can be used.

  Next, FIG. 5 is a diagram for explaining the operation when the luminance threshold value and the delay time parameter are set in the imaging apparatus 1000 according to the present embodiment. A graph 101 in FIG. 5 shows a temporal change in luminance of the subject of the imaging apparatus 1000. This graph 101 shows that the luminance of the subject decreases as time elapses, such as during a sunset.

  The luminance threshold 102 indicates a luminance threshold used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. The luminance threshold 103 indicates a luminance threshold used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2.

  In this embodiment, the luminance threshold value described in the automatic insertion / removal command is normalized to a predetermined range of values. Specifically, the luminance threshold is limited to a value from −1.0 to +1.0. Therefore, as shown in FIG. 5, the specifiable range of the luminance threshold 102 and the luminance threshold 103 is a range from −1.0 to +1.0.

  For example, as shown in FIG. 5, when the luminance value falls below the luminance threshold value 103 due to a decrease in the luminance value of the subject, the CPU 26 sets a delay time in the timing circuit 22 and starts timing in the timing circuit 22. Instruct. Thereby, the time measuring circuit 22 starts time measurement.

  In FIG. 5, the luminance value of the subject is lower than the luminance threshold 103 at point A. The time when it falls below is t1. The CPU 26 sets a delay time in the timing circuit 22 when the time is lower than this, and the optical filter 4 is inserted into the optical path of the imaging optical system 2 until the set delay time elapses. The filter 4 is not removed.

  Such an operation of the CPU 26 can prevent the visible light imaging and the infrared imaging of the imaging apparatus 1000 from being frequently switched even if the graph 101 frequently crosses the luminance threshold 103. Further, such an operation can increase the probability that the luminance value of the subject is stably below the luminance threshold value 103. Such an operation is also effective when the subject brightness rises and falls in a short time due to the influence of flicker of illumination such as a fluorescent lamp.

  Then, the CPU 26 instructs the optical filter driving circuit 24 to remove the optical filter 4 from the optical path of the imaging optical system 2 when the time reaches t2 when the delay time set in the timing circuit 22 elapses. Thereby, the imaging device 1000 performs infrared imaging. The luminance value of the subject at this time (time t2) is point B.

  As described above, in this embodiment, the user causes the imaging apparatus 1000 to transmit an automatic insertion / removal command in which an adjustment value related to insertion / removal of the optical filter 4 is described by operating the client apparatus 2000. Can do. Here, the adjustment value includes a parameter indicating the luminance of the subject and a parameter indicating the delay time.

  As a result, the imaging apparatus 1000 that has received the automatic insertion / removal command frequently inserts and removes the optical filter 4 with respect to the optical path of the imaging optical system 2 even when the luminance value of the subject is near the luminance threshold. Can be prevented. In addition, the imaging apparatus 1000 can prevent frequent insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 even when the luminance of the subject frequently changes due to lighting flicker or the like. it can.

  Next, FIG. 6 is a diagram for explaining a typical command sequence for setting an adjustment value related to insertion / removal of the optical filter 4 between the imaging apparatus 1000 and the client apparatus 2000 according to the present embodiment. It is a sequence diagram. In FIG. 6, ITU-T Recommendation Z. The transaction of this command is described using a so-called message sequence chart defined in the 120 standard.

  Note that the transaction in this embodiment refers to a pair of a command transmitted from the client apparatus 2000 to the imaging apparatus 1000 and a response that the imaging apparatus 1000 returns to the client apparatus 2000 in response thereto. In FIG. 6, it is assumed that the imaging apparatus 1000 and the client apparatus 2000 are connected via an IP network 1500.

  First, through a GetServices transaction, the client device 2000 can acquire the types of Web services supported (provided) by the imaging device 1000 and the address URI for using each Web service.

  Specifically, the client apparatus 2000 transmits a GetServices command to the imaging apparatus 1000. The imaging apparatus 1000 that has received this command returns a response to this command. With this response, the client apparatus 2000 can acquire information indicating whether the imaging apparatus 1000 can execute an automatic insertion / removal command or the like, that is, whether the Imaging_Service is supported. In the present embodiment, this response indicates that the imaging apparatus 1000 supports Imaging_Service.

  Next, through a GetVideoSources transaction, the client apparatus 2000 acquires a list of VideoSources stored in the imaging apparatus 1000. Here, the VideoSource is a set of parameters indicating the performance of one image sensor 6 included in the image capturing apparatus 1000.

  Specifically, the VideoSource includes a VideoSourceToken that is an ID of the VideoSource, a Resolution indicating the resolution of the captured image that can be output, and the like. That is, it is a set of parameters indicating the performance of one image pickup device 6 provided in the image pickup apparatus 1000. The client apparatus 2000 transmits a GetVideoSources command to the imaging apparatus 1000.

  Upon receiving this command, the imaging apparatus 1000 returns a command response. With this return command, the client apparatus 2000 can obtain a VideoSourceToken indicating a VideoSource that can be set for insertion / removal of the optical filter 4. In the present embodiment, this response includes a VideoSourceToken indicating a VideoSource corresponding to the image sensor 6.

  Next, the client device 2000 acquires, from the imaging device 1000, information indicating a command that can be executed by the imaging device 1000 among the insertion command, the removal command, and the automatic insertion / removal command through a GetOptions transaction. Also, with this transaction, the client apparatus 2000 can acquire information indicating adjustment values that can be described in the automatic insertion / removal command.

  The client apparatus 2000 transmits a GetOptions command to the imaging apparatus 1000 (more specifically, an address URI for using the Imaging Service of the imaging apparatus 1000). This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000.

  The imaging apparatus 1000 that has received this command returns a response to this command to the client apparatus 2000. In this example, this response includes IRCutFilterOptions. In this IRCutFilterOptions, information indicating commands that can be executed by the imaging apparatus 1000 among the insertion command, the extraction command, and the automatic insertion / removal command is described.

  Further, in the IRCutFilterOptions, information indicating adjustment values that can be executed (set) by the imaging apparatus 1000 among the adjustment values that can be described in the automatic insertion / removal command is described.

  Next, the client device 2000 acquires information indicating the insertion / removal state of the optical filter 4 with respect to the optical path of the imaging optical system 2 from the imaging device 1000 by a transaction of GetImagingSettings.

  The client apparatus 2000 transmits a GetImagingSettings command to the imaging apparatus 1000. This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000. The imaging apparatus 1000 that has received this command returns a response to this command. In this embodiment, this response includes IRCutFilter Settings. In this IRCutFilter Settings, information indicating whether the optical filter 4 is currently inserted in the optical path of the imaging optical system 2 or whether the optical filter 4 is currently removed from this optical path is described. In the present embodiment, the IRCutFilterSettings describes information indicating that the optical filter 4 is currently inserted in the optical path of the imaging optical system 2.

  Next, the client apparatus 2000 causes the imaging apparatus 1000 to automatically control insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 through a transaction of SetImagingSettings. The client apparatus 2000 transmits a SetImagingSettings command to an address URI for using the ImagingServices of the imaging apparatus 1000. This command includes VideoSourceToken included in the response of GetVideoSource received from the imaging apparatus 1000. Further, in this command, information (IrCutFilter field whose value is “AUTO”) indicating that the imaging apparatus 1000 automatically controls insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2 is described. In addition, an adjustment value (IrCutFilterAutoAdjustment field) is described in this command. The IrCutFilter field and the IrCutFilterAutoAdjustment field will be described later.

  On the other hand, the imaging apparatus 1000 that has received this command returns a response of SetImagingSettings to the client apparatus 2000. This response argument is omitted. Here, this response in which the argument is omitted indicates that the execution of this command by the imaging apparatus 1000 is successful.

  Thus, the imaging apparatus 1000 performs an operation of automatically determining whether the optical filter 4 is inserted into the optical path of the imaging optical system 2 or whether the optical filter 4 is removed from the optical path of the imaging optical system 2.

  Next, FIG. 7 is a flowchart for explaining the GetOptionsResponse transmission process in the imaging apparatus 1000 according to the present embodiment. This process is executed by the CPU 26. When the CPU 26 receives a GetOptions command from the client apparatus 2000 via the I / F 14, the CPU 26 starts executing this process.

  Hereinafter, the flowchart shown in FIG. 7 will be described with reference to FIG. 8 as appropriate. Here, FIG. 8 is a diagram illustrating an example of the GetOptionsResponse transmitted in the GetOptionsResponse transmission process.

  In step S601, the CPU 26 generates a GetOptions response and stores the generated GetOptions response in the EEPROM 28.

  In step S602, the CPU 26 sets ON, OFF, and AUTO to the value of the IrCutFilterModes field of the GetOptions response stored in the EEPROM 28 in step S601.

  Thus, as shown in FIG. 8, three <img20: IrCutFilterModes> tags are associated with the <ImagingOptions20> tag in the GetOptions response. Furthermore, each of the three <Img20: IrCutFilterModes> tags is associated with ON, OFF, and AUTO.

  Note that the IrCutFilterModes field whose value is ON indicates that the imaging apparatus 1000 can accept an insertion instruction command. An IrCutFilterModes field whose value is OFF indicates that the imaging apparatus 1000 can accept a removal instruction command. Further, the IrCutFilterModes field whose value is AUTO indicates that the imaging apparatus 1000 can accept an automatic insertion / removal command.

  In step S603, the CPU 26 sets ToOn and ToOff in the value of the Mode field of the GetOptions response stored in the EEPROM 28 in step S601.

  Thus, as shown in FIG. 8, three <Img20: Mode> are associated with the <IrCutFilterAutoAdjustmentOptions> tag in the GetOptions response. Further, each of the three <Img20: Mode> tags is associated with ToOn and ToOff.

  The Mode field whose value is ToOn indicates that the imaging apparatus 1000 can use an adjustment value for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. The Mode field whose value is ToOff indicates that the adjustment value can be used for determining whether or not the imaging apparatus 1000 removes the optical filter 4 from the optical path of the imaging optical system 2.

  For example, a GetOptions response in which a Mode field whose value is ToOn and a Mode field whose value is ToOff is described indicates the following.

  That is, the adjustment value used by the imaging apparatus 1000 can be set separately for each of the case where the optical filter 4 is inserted into the optical path of the imaging optical system 2 and the case where the optical filter 4 is removed from the optical path of the imaging optical system 2. It can be done.

  In step S604, the CPU 26 sets true to the value of the BoundaryOffset field of the GetOptions response stored in the EEPROM 28 in step S601. Further, the CPU 26 sets PT0S as the value of the Min field of the GetOptions response stored in the EEPROM 28 in step S601, and sets PT30M as the value of the Max field of this response.

  As a result, as shown in FIG. 8, the <img20: BoundaryOffset> tag is associated with the <IrCutFilterAutoAdjustmentOptions> tag in the GetOptions response. Furthermore, an <img20: ResponseTime> tag is associated with the <IrCutFilterAutoAdjustmentOptions> tag.

  The <img20: BoundaryOffset> tag is associated with true. The <img20: ResponseTime> tag is associated with the <img20: Min> tag and the <img20: Max> tag. Here, PT0S is associated with the <img20: Min> tag. Further, PT30M (30 minutes) is associated with the <img20: Max> tag.

  Note that a BoundaryOffset field whose value is true indicates that BoundaryOffset can be set in the imaging apparatus 1000. The <img20: Min> tag indicates the minimum time (shortest time) that can be set in the ResponseTime field. The <img20: Max> tag indicates the maximum time (longest time) that can be set in the ResponseTime field.

  That is, <img20: Min> and <img20: Max> indicate a time range that can be set in the ResponseTime field.

  In step S605, the CPU 26 instructs the I / F 14 to transmit the GetOptions response stored in the EEPROM 28 in step S601 to the client device 2000.

  Next, FIG. 9 is a diagram illustrating an example of the configuration of the SetImagingSettings command. In SetImagingSettings shown in FIG. 9A, AUTO is set in the value of the IrCutFilter field. More specifically, in the SetImagingSettings command, AUTO is associated with the <IrCutFilter> tag.

  As a result, the SetImagingSettings command shown in FIG. 9A corresponds to an automatic insertion / removal command for causing the imaging apparatus 1000 to automatically control insertion / removal of the optical filter 4 with respect to the optical path of the imaging optical system 2.

  In the SetImagingSettings command shown in FIG. 9A, ToOn is set in the value of the BoundaryType field. More specifically, in this SetImagingSettings command, a <BoundaryType> tag is associated with the <IrCutFilterAutoAdjustment> tag. Further, a value of ToOn is associated with the <BoundaryType> tag.

  In the SetImagingSettings command shown in FIG. 9A, 0.25 is set in the value of the BoundaryOffset field. More specifically, in this SetImagingSettings command, the <IrCutFilterAutoAdjustment> tag is associated with the <BoundaryOffset> tag. Furthermore, 0.25 is associated with this <BoundaryOffset> tag.

  Furthermore, in the SetImagingSettings command shown in FIG. 9A, PT1M30S is set as the value of the ResponseTime field. More specifically, in this SetImagingSettings command, the <IrCutFilterAutoAdjustment> tag is associated with the <ResponseTime> tag. The <ResponseTime> tag is associated with PT1M30S. The time set in the value of the ResponseTime field corresponds to a value related to the delay time when the optical filter 4 is inserted and removed.

  Accordingly, the SetImagingSettings command shown in FIG. 9A can be said to be a command for instructing the imaging apparatus 1000 to do the following. That is, when the optical filter 4 is inserted into the optical path of the imaging optical system 2, the value of the BoundaryOffset field and the value of the ResponseTime field are used by the imaging apparatus 1000.

  Subsequently, in SetImagingSettings shown in FIG. 9B, AUTO is set as the value of the IrCutFilter field. More specifically, in this SetImagingSettings command, AUTO is associated with the <IrCutFilter> tag.

  In the SetImagingSetting command shown in FIG. 9B, the value of the BoundaryType field in the IrCutFilterAutoAdjustment field is set to ToOn.

  More specifically, in this SetImagingSettings command, a <BoundaryType> tag is associated with the <IrCutFilterAutoAdjustment> tag. The <BoundaryType> tag is associated with ToOff.

  In the SetImagingSettings command shown in FIG. 9B, the value of the BoundaryOffset field in the IrCutFilterAutoAdjustment field is set to 0.16.

  More specifically, in this SetImagingSettings command, a <BoundaryOffset> tag is associated with the first <IrCutFilterAutoAdjustment> tag. The <BoundaryOffset> tag is associated with 0.16.

  Further, in the SetImagingSettings command shown in FIG. 9B, the value of ResponseTime in the IrCutFilterAutoAdjustment field is set to PT1M10S.

  Accordingly, the SetImagingSettings command shown in FIG. 9B can be said to be a command for instructing the imaging apparatus 1000 to do the following. That is, when the optical filter 4 is removed from the optical path of the imaging optical system 2, the value of the BoundaryOffset field and the value of the ResponseTime field are used by the imaging apparatus 1000.

  In the SetImagingSettings command shown in FIG. 9B, the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOff is 0.16.

  Next, FIG. 10 is a flowchart for explaining SetImagingSettings reception processing in the imaging apparatus 1000 according to the present embodiment.

  This process is executed by the CPU 26. When the CPU 26 receives a SetImagingSettings command from the client device 2000 via the I / F 14, the CPU 26 starts executing this process. Further, it is assumed that the SetImagingSettings command received by the I / F 14 is stored in the EEPROM 28.

  In step S <b> 901, the CPU 26 reads a SetImagingSettings command from the EEPROM 28.

  In step S902, the CPU 26 determines whether or not the value of the BoundaryType field of ToOn or ToOff is described in the command read in step S901.

  If the CPU 26 determines that only the BoundaryType field whose value is ToOn is described, the process proceeds to step S903. If it is determined that only the BoundaryType field whose value is ToOff is described, the process proceeds to step S905.

  On the other hand, if the CPU 26 determines that the BoundaryType field with the value ToOn and the BoundaryType field with the value ToOff are described, the process proceeds to step S907. If it is determined that the BoundaryType field whose value is ToOn and the BoundaryType field whose value is ToOff are not described, the processing ends.

  In addition, the CPU 26 in this embodiment describes whether the luminance threshold value is described in common when the optical filter 4 is inserted into the optical path of the imaging optical system 2 and when the optical filter 4 is extracted, or separately. This corresponds to a determination unit that determines whether or not it is performed.

  In step S903, the CPU 26 reads the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOn in the command read in step S901. In the case of the command shown in FIG. 9A, the CPU 26 reads 0.25 as the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOn.

  In step S904, the CPU 26 reads the value of ToOff corresponding to the value of ToOn read in step S903 from the table stored in advance in the EEPROM 28. FIG. 11 shows an example of this table. In this table, the BoundaryOffset value is associated with the ToOff luminance threshold and the ToOn luminance threshold.

  On the other hand, the value of the BoundaryOffset field corresponding to the BoundaryType field of ToOn may be offset without reading from a pre-stored table, and the value may be used as the ToOff luminance threshold. At this time, the offset amount of the ToOff luminance threshold value may be a uniform value (fixed value), or the difference between the subject luminance values obtained from the luminance measurement circuit 18 when the optical filter 4 of the imaging apparatus 1000 is inserted and withdrawn is determined as the luminance threshold value. A value applied to may be used. Note that offsetting means adding or subtracting values.

  Further, the value of ToOff may be a default value stored in advance in the EEPROM 28, or the same value as ToOn may be used. Further, the value of the BoundaryType field of ToOff in the command received before receiving this SetImagingSettings may be used.

  Thus, the CPU 26 in this embodiment automatically determines the other value when only one value is described when the optical filter 4 is inserted into the command or when the optical filter 4 is removed. This corresponds to an automatic determination unit having a function.

  In step S905, the CPU 26 reads the value of the BoundaryOffset field corresponding to the BoundaryType field whose value is ToOff in the command read in step S901. In the case of the command shown in FIG. 9B, the CPU 26 reads out 0.16 as the value of BoundaryOffset corresponding to the BoundaryType field whose value is ToOff.

  In step S906, the CPU 26 reads the value of ToOn corresponding to the value of ToOff read in step S903 from the table stored in advance in the EEPROM 28. (See Figure 11 for table examples)

  On the other hand, the value of the BoundaryOffset field corresponding to the BoundaryType field of ToOff may be offset without reading from the table stored in advance, and the value may be used as the ToOn luminance threshold. At this time, the offset amount of the brightness threshold value of ToOn may be a uniform value (fixed value), or the difference between the subject brightness values obtained from the brightness measurement circuit 18 when the optical filter 4 is inserted and removed from the imaging apparatus 1000 A value applied to may be used.

  The value of ToOn may be a default value stored in advance in the EEPROM 28, or the same value as ToOff may be used. Further, the value of the BoundaryType field of ToOff in the command received before receiving this SetImagingSettings may be used.

  In step S907, the CPU 26 stores the brightness threshold value in the EEPROM 28.

  More specifically, the CPU 26 stores the luminance threshold value corresponding to the value read in step S903 in the EEPROM 28 as the luminance threshold value used for determining whether or not the optical filter 4 is inserted in the optical path of the imaging optical system 2. .

  Further, the CPU 26 stores the luminance threshold corresponding to the value read in step S905 in the EEPROM 28 as a luminance threshold used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2. After having memorize | stored in this way, CPU26 advances a process to step S908.

  In the present embodiment, it goes without saying that the SetImagingSettings command received by the I / F 14 is information necessary for the CPU 26 to perform the determination in step S902.

  In step S <b> 908, the CPU 26 instructs the I / F 14 to transmit a response of SetImagingSettings to the client apparatus 2000.

  Next, FIG. 12 is a flowchart for explaining an automatic day / night process which is a process for automatically causing the imaging apparatus 1000 to control whether or not the optical filter 4 is inserted into the optical path of the imaging optical system 2. This process is executed by the CPU 26.

  In step S <b> 1001, the CPU 26 reads a luminance threshold value used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2 from the EEPROM 28. Then, the CPU 26 sets the read luminance threshold value in the determination circuit 20 as a luminance threshold value used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2.

  In step S <b> 1002, the CPU 26 reads from the EEPROM 28 a delay time used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. Then, the CPU 26 sets the read delay time in the timer circuit 22 as a delay time used for determining whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2. This delay time is shown as “responsiveness time threshold” in FIG.

  In step S <b> 1003, the CPU 26 instructs the determination circuit 20 to acquire the current luminance value of the subject of the imaging apparatus 1000 from the luminance measurement circuit 18.

  In step S1004, the CPU 26 instructs the determination circuit 20 to compare the luminance threshold set in step S1001 with the luminance value acquired in step S1003. Note that in step S1004 in FIG. 12, the luminance value acquired in step S1003 is shown as an “estimated luminance value”.

  In step S1005, the CPU 26 determines whether or not the luminance value acquired in step S1003 is equal to or higher than the luminance threshold set in step S1001 as a result of the comparison in step S1004.

  If the CPU 26 determines that the brightness value acquired in step S1003 is greater than or equal to the brightness threshold set in step S1001, the CPU 26 advances the process to step S1007. On the other hand, if the CPU 26 determines that the luminance value acquired in step S1003 is not greater than or equal to the luminance threshold set in step S1001, the CPU 26 returns the process to step S1004.

  In step S1006, the CPU 26 instructs the timing circuit 22 to stop timing.

  In step S1007, the CPU 26 instructs the timing circuit 22 to start timing.

  Since steps S1008 and S1009 are the same as steps S1004 and S1005, description thereof is omitted.

  In step S1010, the CPU 26 determines whether or not the timer circuit 22 has received a notification that the delay time set in step S1002 has elapsed since the start of timing in step S1007. In step S1010 in FIG. 12, this delay time is shown as “responsiveness time elapsed”.

  If the CPU 26 determines that it has received a notification from the timing circuit 22 that the delay time set in step S1002 has elapsed since the start of timing in step S1007, the process proceeds to step S1011.

  On the other hand, if the CPU 26 determines that it has not received a notification from the timing circuit 22 that the delay time set in step S1002 has elapsed since it started timing in step S1007, it returns the process to step S1008.

  In step S <b> 1011, the CPU 26 instructs the optical filter driving circuit 24 to insert the optical filter 4 into the optical path of the imaging optical system 2. As a result, the imaging apparatus 1000 performs visible light imaging.

  As described above, this embodiment assumes the following case. That is, only the value of the BoundaryOffset field corresponding to the BoundaryType field of either ToOn or ToOff is described in the command.

  Even in such a case, the imaging apparatus 1000 according to the present embodiment can appropriately determine the value of the BoundaryOffset field and the value of the BoundaryOffset field of the BoundaryType field of ToOn.

  In the present embodiment, the process of automatically controlling the imaging apparatus 1000 to determine whether or not to insert the optical filter 4 in the optical path of the imaging optical system 2 has been described with reference to FIG. Here, processing for automatically controlling the imaging apparatus 1000 to determine whether or not to remove the optical filter 4 from the optical path will be described below.

  In step S <b> 1001, the CPU 26 reads from the EEPROM 28 a luminance threshold value used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2. Then, the CPU 26 sets the read luminance threshold value in the determination circuit 20 as a luminance threshold value used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2.

  In step S <b> 1002, the CPU 26 reads from the EEPROM 28 a delay time used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2. Then, the CPU 26 sets the read delay time in the timer circuit 22 as a delay time used for determining whether or not to remove the optical filter 4 from the optical path of the imaging optical system 2.

  Since steps S1003 and S1004 are the same as steps S1003 and S1004 described above, description thereof is omitted.

  In step S1005, the CPU 26 determines whether the luminance value acquired in step S1003 is equal to or lower than the luminance threshold set in step S1001 as a result of the comparison in step S1004.

  If the CPU 26 determines that the luminance value acquired in step S1003 is less than or equal to the luminance threshold set in step S1001, the CPU 26 advances the process to step S1007. On the other hand, if the CPU 26 determines that the luminance value acquired in step S1003 is not less than or equal to the luminance threshold set in step S1001, the CPU 26 returns the process to step S1004.

  Since steps S1006 to S1010 are the same as steps S1006 to S1010 described above, description thereof will be omitted.

  In step S <b> 1011, the CPU 26 instructs the optical filter drive circuit 24 to remove the optical filter 4 from the optical path of the imaging optical system 2. Thereby, the imaging apparatus 1000 performs infrared imaging.

  As described above, in the imaging apparatus 1000 according to the present embodiment, when only one value is described when the optical filter 4 is inserted into the SetImagingSettings command received by the I / F 14 or when the optical filter 4 is removed. The other value is automatically determined.

  Here, SetImagingSettings includes the value of the BoundaryType field regarding ToOn and ToOff. However, both values are not always described in commands received via the network. Therefore, only one value may be described. For this reason, when the setting is not performed as intended by the user, the imaging apparatus 1000 may not be able to accept the other value.

  However, even in such a case, the image pickup device can be used based on the settings made by the external device without unintentionally inserting or removing the optical filter in the optical path of the image pickup optical system or causing the picked-up image to be abnormal. 1000 must work properly.

  The imaging apparatus 1000 automatically determines the other value when only one value is described when the optical filter 4 is inserted in the SetImagingSettings command or when the optical filter 4 is removed.

  As a result, the imaging apparatus 1000 can operate appropriately even if only one value is set. As a result, when performing settings related to optical filter insertion / removal control from an external device via a network, it is possible to increase the degree of freedom of settings related to the subject brightness of the imaging device, delay time related to optical filter insertion / removal, etc. it can.

  Further, in the present embodiment, the CPU 26 determines whether only one value is described when the optical filter 4 is inserted into the SetImagingSettings command or when the optical filter 4 is removed. Therefore, the automatic determination operation can be performed at a more appropriate timing according to the received command.

  Further, in this embodiment, when it is determined in FIG. 10 that only one value is described in the case where the optical filter 4 is inserted or the optical filter 4 is removed, a certain period of time is determined in steps S904 and S906. The other value may not be automatically determined until the time has elapsed.

  That is, the operation in this embodiment may be performed when a SetImagingSettings command in which the other value is described is not received even after a certain time has elapsed.

  Further, in this embodiment, when it is determined in FIG. 10 that only one value is described in the case where the optical filter 4 is inserted or the optical filter 4 is removed, the other is determined in steps S904 and S906. The client apparatus 2000 may be notified that the additional setting of the value of the user is urged.

(Example 2)
Subsequently, Embodiment 2 of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the component same as the above-mentioned Example, and the description may be abbreviate | omitted.

  Here, in the above-described first embodiment, the operation of the imaging apparatus when only the value corresponding to either BoundaryType field of ToOn or ToOff is described in the command is exemplified.

  FIG. 13 is a diagram illustrating an example of an IrCutFilterAutoAdjustment setting screen in the client device 2000 according to the present embodiment. This screen is displayed on the display unit 422.

  The optical filter type selection pane 301 in FIG. 13 includes a ToOn selection check box 305, a ToOff selection check box 307, and a BoundaryOffset setting numerical value box 309.

  The optical filter type selection pane 301 includes a delay time setting numerical value box 311. The optical filter setting pane 315 is provided with a first luminance threshold setting scale 317, a second luminance threshold setting scale 319, a first delay time setting scale 321, and a second delay time setting scale 323. Furthermore, a setting button 325 and a cancel button 327 are provided on the setting screen shown in FIG.

  Here, in the optical filter setting pane 315, the vertical axis indicates the luminance value, and the horizontal axis indicates the delay time. In particular, in the optical filter setting pane 315, the horizontal axis (on the Time axis) indicates a luminance value 0 (zero), and the upper limit (upper end) indicates a normalized luminance value 1.0. Further, the lower limit (lower end) indicates a normalized luminance value −1.0. In the optical filter setting pane 315, the left limit (left end) indicates the delay time 0 (zero).

  FIG. 13 is an example of a setting screen when the optical filter 4 is inserted in the optical path of the imaging optical system 2. That is, the screen in FIG. 13 is a setting screen that is used when a SetImagingSettings command in which a BoundaryType field whose value is ToOn is described is transmitted to the imaging apparatus 1000.

  The ToOn selection check box 305 in FIG. 13 is selected by the user. For this reason, the second luminance threshold setting scale 319 and the second delay time setting scale 323 are grayed out. That is, the second luminance threshold setting scale 319 and the second delay time setting scale 323 are in an inoperable state.

  The user slides the first brightness threshold setting scale 317 up and down to set the user's desired BoundaryOffset value. When the first brightness threshold setting scale 317 is operated by the user, the value of the ToOn equivalent part in the BoundaryOffset setting numerical value box 309 changes in conjunction with this operation.

  On the other hand, the user can also directly input a value into the ToOn equivalent part in the BoundaryOffset setting numerical value box 309. When a value is input to the ToOn equivalent part by the user, the first luminance threshold setting scale 317 moves up and down according to the input value.

  Thus, the user can roughly grasp the value of BoundaryOffset from the position of the first luminance threshold setting scale 317. Further, since this position and the value of the ToOn equivalent part in the BoundaryOffset setting numerical value box 309 are linked, the user can accurately grasp the value of BoundaryOffset by this ToOn equivalent part.

  When the setting button 325 is pressed while the first luminance threshold setting scale 317 is arranged on the Time axis, the client device 2000 transmits a SetImagingSettings command in which the BoundaryOffset field is omitted.

  Similarly, even when the setting button 325 is pressed in a state where 0 (zero) is input in the ToOn equivalent part of the BoundaryOffset setting numerical value box 309, the client apparatus 2000 transmits the omitted SetImagingSettings command.

  For example, a GUI component for instructing to omit the BoundaryOffset field in the SetImagingSettings command may be separately displayed on the display unit 422.

  Specifically, a BoundaryOffset field omission check box is arranged on the screen of FIG. 13 as such a GUI component. Then, when this check box is selected by the user, the BoundaryOffset field of the SetImagingSettings command may be omitted.

  Also, the user sets the value of ResponseTime desired by the user by sliding the first delay time setting scale 321 left and right. When the first delay time setting scale 321 is operated by the user, the time display of the ToOn equivalent part in the delay time setting numerical value box 311 changes in conjunction with this operation.

  On the other hand, the user can also directly input the time into the ToOn equivalent part in the delay time setting numerical value box 311. Then, when time is input to this ToOn equivalent part by the user, the first delay time setting scale 321 moves to the left and right according to the input time.

  It is assumed that the setting button 325 is pressed in a state where the first delay time setting scale 321 is arranged at the left end of the optical filter setting pane 315. In such a case, the client apparatus 2000 transmits a SetImagingSettings command in which the ResponseTime field is omitted.

  Similarly, it is assumed that the setting button 325 is pressed in a state where 0 (zero) is input to all numerical value boxes in the ToOn equivalent part in the delay time setting numerical value box 311. Even in such a case, the client apparatus 2000 assumes a SetImagingSettings command in which the ResponseTime field is omitted.

  In this embodiment, the first delay time setting scale 321 is arranged at the left end of the optical filter setting pane 315, or the response time field is omitted by inputting 0 in the ToOn equivalent part of the delay time setting numerical value box 311. Can be instructed. However, the present invention is not limited to this.

  For example, a GUI component for instructing to omit the ResponseTime field in the SetImagingSettings command may be separately displayed on the display unit 422.

  Specifically, a ResponseTime field omission check box is arranged on the screen of FIG. 13 as such a GUI component. Then, when this check box is selected by the user, the ResponseTime field of the SetImagingSettings command may be omitted.

  In addition, the client apparatus 2000 according to the present embodiment may transmit a GetOptions command to the imaging apparatus 1000 before displaying the setting screen illustrated in FIG. 13 on the display unit 422. Then, the client device 2000 may update the setting screen of FIG. 13 displayed on the display unit 422 in accordance with the GetOptions response transmitted from the imaging device 1000.

  Here, this response includes an IrCutFilterAutoAdjustmetOptions field. In this field, the value of the BoundaryType field that can be received by the imaging apparatus 1000 is described.

  Moreover, although the example regarding ToOn was shown in a present Example, when the ToOff selection check box 307 in FIG. 13 is selected by the user. Therefore, the same operation can be performed by operating the second luminance threshold setting scale 319, the second delay time setting scale 323, and the like.

  Next, FIG. 14 is a flowchart for explaining SetImagingSettings transmission processing in the client apparatus 2000 according to the present embodiment.

  This process is executed by the CPU 426. Then, the CPU 426 determines whether or not the setting button 325 has been pressed. If it is determined that the setting button 325 has been pressed, the CPU 426 starts this processing and determines that the setting button 325 has not been pressed. Does not start this processing.

  In step S1201, the CPU 426 generates a SetImagingSettings command and stores the generated SetImagingSettings command in the EEPROM 428. The value of the IrCutFilter field in the stored SetImagingSettings command is AUTO.

  Thereby, as shown in FIG. 9A or 9B, AUTO is associated with the <IrCutFilter> tag of the stored SetImagingSettings command.

  In step S1202, the CPU 426 determines which of the ToOn selection check box 305 or the ToOff selection check box 307 is selected.

  If the CPU 426 determines that only the ToOn selection check box 305 is selected, the CPU 426 advances the process to step S1203. If the CPU 426 determines that only the ToOff selection check box 307 is selected, the CPU 426 advances the process to step S1209. If it is determined that both the ToOn selection check box 305 and the ToOff selection check box 307 are selected, the process proceeds to step S1214. In step S1203, the CPU 426 adds a BoundaryType field whose value is ToOn to the command stored in step S1201.

  As a result, as shown in FIG. 9A, a <IrCutFilterAutoAdjustment> tag is described in the stored command. Further, in this command, a <BoundaryType> tag is associated with and described in the <IrCutFilterAutoAdjustment> tag.

  In addition, ToOn is described and associated with this <BoundaryType> tag in this command.

  In step S1204, the CPU 426 determines whether or not a value is set in the ToOn equivalent part in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that a value is set in the ToOn equivalent part in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1205.

  On the other hand, if the CPU 426 determines that no value is set in the ToOn equivalent part in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1206.

  In step S1205, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of this BoundaryOffset field is a value set in the ToOn equivalent part in the BoundaryOffset setting numerical value box 309.

  Now, as shown in FIG. 9A, in this stored command, a <BoundaryOffset> tag is associated with and described in the <IrCutFilterAutoAdjustment> tag of this command. Further, in this command, 0.25 is associated with and described in this <BoundaryOffset> tag.

  In step S1206, the CPU 426 determines whether or not a value is set in the ToOn equivalent part in the delay time setting numerical value box 311. If the CPU 426 determines that a value is set in the ToOn equivalent part in the delay time setting numerical value box 311, the process proceeds to step S1207.

  On the other hand, if the CPU 426 determines that a value is not set in the ToOn equivalent part in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1207, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in the ToOn equivalent part in the delay time setting numerical value box 311.

  Thus, for example, as shown in FIG. 9A, in the stored command, the <ResponseTime> tag is associated with and described in the <IrCutFilterAutoAdjustment> tag of this command. Further, in this command, PT1M15S is associated with and described in the <ResponseTime> tag.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000.

  On the other hand, in step S1209, the CPU 426 adds a BoundaryType field whose value is ToOff to the command stored in step S1201.

  Thereby, as shown in FIG. 9B, the <IrCutFilterAutoAdjustment> tag is described in the stored command. Further, in this command, a <BoundaryType> tag is associated with and described in the <IrCutFilterAutoAdjustment> tag.

  In addition, in this command, ToOff is associated with and described in this <BoundaryType> tag.

  In step S <b> 1210, the CPU 426 determines whether or not a value is set in a ToOff equivalent part in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that a value is set in the ToOff equivalent part in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1211.

  On the other hand, if the CPU 426 determines that a value is not set in the ToOff equivalent part in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1212.

  In step S1211, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of this BoundaryOffset field is a value set in the ToOff equivalent part in the BoundaryOffset setting numerical value box 309.

  Now, as shown in FIG. 9B, in this stored command, the <BoundaryOffset> tag is associated with and described in the <IrCutFilterAutoAdjustment> tag of this command. Further, in this command, 0.16 is associated with and described in the <BoundaryOffset> tag.

  In step S <b> 1212, the CPU 426 determines whether or not a value is set in the ToOff equivalent part in the delay time setting numerical value box 311. If the CPU 426 determines that a value is set in the ToOff equivalent part in the delay time setting numerical value box 311, the process proceeds to step S <b> 1213.

  On the other hand, if the CPU 426 determines that a value is not set in the portion corresponding to ToOff in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1213, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in a portion corresponding to ToOff in the delay time setting numerical value box 311.

  Thus, for example, as shown in FIG. 9B, the <ResponseTime> tag is associated with the <IrCutFilterAutoAdjustment> tag of this command and described in the stored command. Further, in this command, PT1M10S is described in association with this <ResponseTime> tag.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000.

  In step S1214, the CPU 426 adds Boundary Type fields whose values are ToOn and ToOff to the command stored in step S1201. Moreover, in this command, ToOn and ToOff are associated with and described in this <BoundaryType> tag.

  In step S <b> 1215, the CPU 426 determines whether values are set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309. If the CPU 426 determines that values are set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1216.

  On the other hand, if the CPU 426 determines that values are not set in the ToOn and ToOff equivalent parts in the BoundaryOffset setting numerical value box 309, the process proceeds to step S1217.

  In step S1216, the CPU 426 adds a BoundaryOffset field to the command stored in step S1201. The value of the BoundaryOffset field is a value set in a portion corresponding to ToOn and ToOff in the BoundaryOffset setting numerical value box 309.

  In step S <b> 1217, the CPU 426 determines whether values are set in the ToOn and ToOff equivalent parts in the delay time setting numerical value box 311. If the CPU 426 determines that a value is set in the ToOff equivalent part in the delay time setting numerical value box 311, the process proceeds to step S <b> 1218.

  On the other hand, if the CPU 426 determines that values are not set in the ToOn and ToOff equivalent parts in the delay time setting numerical value box 311, the process proceeds to step S1208.

  In step S1218, the CPU 426 adds a ResponseTime field to the command stored in step S1201. The value of the ResponseTime field is a value set in a portion corresponding to ToOn and ToOff in the delay time setting numerical value box 311.

  In step S1208, the CPU 426 instructs the I / F 414 to transmit the command stored in step S1201 to the imaging apparatus 1000.

  If it is determined in step S1215 that a value corresponding to ToOn or ToOff has not been set in the BoundaryOffset setting numerical value box 309, each field that is not set is not added.

  If it is determined in step S1217 that a value corresponding to ToOn or ToOff is not set in the delay time setting numerical value box 311, the fields are not added for each item that is not set.

  In step S1312, the CPU 426 displays BoundaryOffset corresponding to BoundaryOffset of ToOn and ToOff described in the GetImagingSettings response. Here, the value is displayed in the BoundaryOffset setting numerical value box 309.

  In step S <b> 1313, the CPU 426 determines whether the response time ToOn and ToOff is set.

  When the response time of ToOn and ToOff is set, the process proceeds to step S1314, and when it is not set, the process ends.
