The frame 133 reciprocates the lens array 131 between the pre-exposure position P1 and the exposure completion position P2 as shown in FIG. As described above, the frame 133 includes a first string S1 and a second string S2, which will be described later, formed on one end 133c and the other end 133d of the frame 133. It is fixed to the 2nd ring part 133a and 133b, respectively, and the 1st string S1 or the 2nd string S1, S2 is pulled in the pulling direction.

In addition, one end 151a of the first light blocking film 151 of the light blocking member 150 is connected to one end 133c and the second light blocking film of the light blocking member 150 is connected to the other end 133d. 153) One end 153a is connected. Therefore, the frame 133 moves between the pre-exposure position P1 and the exposure completion position P2 together with the light blocking member 150.

In addition, a plurality of contact protrusions 133e and 133f are formed on the upper surfaces of both sides of the frame 133, and the plurality of contact protrusions 133e and 133f may include the frame 133 and the bottom surfaces 135a and 135b of the shutter 135. Minimize the contact area. In this case, the shutter 135 has upper surfaces 135c and 135d in contact with the bottom surface of the first portion 113a of the upper housing 113, and the contact area of the shutter 135 is formed by the plurality of contact protrusions 133e and 133f. 133 and the contact area between the bottom of the shutter 135 is larger.

Accordingly, when the frame 133 is towed by the first string S1 or the second string S2, the shutter 135 may generate frictional force between the bottom surfaces of the first portions 113a of the upper housing 113. Since it is larger than the friction force between the frames 133, it is slower than the moving speed of the frame 133.

Therefore, as shown in FIG. 13, when the frame 133 moves from the exposure completed position P2 to the pre-exposure position P1 (C direction), the frame according to the difference in the moving speed between the frame 133 and the shutter 135 is obtained. One end 133c of 133 pushes and moves the first latching jaws 135e and 135f of the shutter 135. At this time, since the position of the light passing hole 135i of the shutter 135 is shifted from the position of the lens array 131, the lens array 131 is closed by the shutter 135. As a result, the instant film 140 is shielded by the shutter 135 and the light blocking member 150 while the lens array 131 moves from the exposure completed position P2 to the pre-exposure position P1.

On the contrary, as shown in FIG. 14, when the frame 133 moves from the pre-exposure position P1 to the exposure completion position P2 (D direction), the frame according to the difference in the moving speed between the frame 133 and the shutter 135 is performed. One end 133d of 133 pushes and moves the second latching jaws 135g and 135h of the shutter 135. At this time, since the position of the light passing hole 135i of the shutter 135 is changed to correspond to the position of the lens array 131, the lens array 131 is opened. Accordingly, while the lens array 131 moves from the pre-exposure position P1 to the exposure completion position P2, the light emitted from the screen 401 of the display device 400 is transferred to the instant film through the lens array 131. The photosensitive surface 141 of the instant film 140 is exposed to the incident light at 140.

The light blocking member 150 may be made of an opaque film having an elastic force by itself, and includes a first light blocking film 151 and a second light blocking film 153.

Referring to FIG. 10, the first light blocking film 151 is inserted into the first cylindrical groove 111e in a state where the other end 151b is rolled roundly. The other end 151b is unfolded while being unfolded when the frame 133 moves to the pre-exposure position P1, and then dried again by its elastic force when the frame 133 is moved to the exposure complete position P2.

Similarly, the second light shielding film 153 is inserted into the second cylindrical groove 111f in a state where the other end portion 153b is rolled roundly. In this case, the other end 153b is unfolded while being released when the frame 133 moves to the exposure completed position P2, and then dried again by its elastic force when the frame 133 moves to the pre-exposure position P1. do.

The input unit 430 includes a plurality of function keys for setting or selecting various functions supported by the display apparatus 400. In detail, the input unit 430 may receive an image display command from a user or a print command for the displayed image. Meanwhile, in the illustrated example, although the display unit 420 and the input unit 430 are illustrated as separate components, the display unit 420 and the input unit 430 may be implemented as a device in which input and output are simultaneously implemented, such as a touch screen. In addition, in the implementation, a separate physical key may be provided in the display apparatus 400 together with the touch screen.

The input unit 430 may receive a selection of an application (or program) for a print job using the portable image forming apparatus 100. The input unit 430 may receive an image (or content) to be printed in the driving state of the corresponding application. Meanwhile, in the present exemplary embodiment, the image is selected after the application is selected. However, the image may be implemented in a form in which the application is driven in response to a user print command after the user selects the image.

Herein, the portable image forming apparatus is a printing apparatus that exposes the instant film using the screen light displayed on the display unit 420. The instant printing apparatus having the structure as described with reference to FIG. The instant printing apparatus according to the second embodiment, the instant printing apparatus according to the third embodiment described with reference to FIG. 39, and the instant printing apparatus according to the fourth embodiment described with reference to FIG. 49, having the above-described structure In addition to the device, it may be a device for exposing the instant film by using the exposure member 130 that is manually driven.

The input unit 430 may receive a print command for the selected image. Meanwhile, when the input unit 430 is implemented as a touch screen, such a print command may be input as a print command when a touch corresponding to an arrangement form of a plurality of touch sensors disposed on the portable image forming apparatus 100 is input. Can be.

The input unit 430 may receive a print option of the corresponding image. The printing options may be brightness, exposure, saturation, etc., and other printing options may be selected.

The storage unit 440 stores a program for driving the display apparatus 400. In detail, the storage unit 440 may store a program, which is a set of various commands required for driving the display apparatus 400. Here, the program includes not only an application program for providing a specific service but also an operating program for driving the application program. The application program may be for a print job using a portable image forming apparatus.

The storage unit 440 includes content. In detail, the storage unit 440 may store not only the contents (eg, a photographic image or a video) generated by the imaging unit 450 to be described below, but also the contents received through the communication interface unit 410.

The storage unit 440 may store the exposure speed detected by the detection unit 460 to be described later, and store the information received from the NFC patch attached to the portable image forming apparatus 100 through the communication interface unit 410. It may be. The storage unit 440 may store information of a refresh rate corresponding to the portable image forming apparatus.

The storage unit 440 may be implemented as a storage medium and an external storage medium in the display device 400, for example, a removable disk including a USB memory, a web server through a network, and the like.

The imaging unit 450 captures an image. In detail, the imaging unit 450 may photograph the exposure position of the portable image forming apparatus. The photographing result may be transmitted to the sensing unit 460 which will be described later.

The detector 460 detects an exposure area of the portable image forming apparatus 100. In detail, the detector 460 may detect the exposure area according to the positions of the plurality of touch sensors of the portable image forming apparatus on the touch screen. Here, the exposure speed refers to a moving speed of the exposure member of the portable image forming apparatus 100, and may also be referred to as a scan speed of the portable image forming apparatus 100. Such a sensing method will be described later with reference to FIG. 63. In this case, the sensing unit 460 may detect an arrangement direction between the portable image forming apparatus and the display apparatus using a plurality of touch sensors on the touch screen.

The detector 460 detects an exposure speed of the portable image forming apparatus 100. In detail, the detector 460 may detect the exposure speed according to the position of the touch sensor of the portable image forming apparatus on the touch screen. Such a sensing method will be described later with reference to FIG. 64. Alternatively, the detector 460 may detect an exposure speed according to the exposure position photographed by the imaging unit 450. The detected exposure speed may be stored in the storage 440.

The image processor 470 adjusts the size of the image to be displayed on the display 420. In detail, the image processor 470 may adjust the size and position of the image so that the image is displayed in the area of the display unit 420 corresponding to the exposure area of the portable image forming apparatus.

The image processor 470 adjusts the brightness of the image displayed on the display 420. Specifically, the image processor 470 adjusts the brightness value of the image so that the same amount of light is provided to the instant film for each exposure position of the portable image forming apparatus.

More specifically, since the portable image forming apparatus according to the present embodiment uses the exposure member 130 which is manually driven, the moving speed of the exposure member 130 during exposure may not be constant. Accordingly, the display apparatus 400 according to the present exemplary embodiment detects the moving speed (ie, the exposure speed) of the exposure member 130 in the sensing unit 460 and corrects the deviation of the exposure speed. The brightness of the image is adjusted to have a brightness value corresponding to the detected exposure speed with respect to the direction of the corresponding image.

For example, in the case where the entire image has the same brightness value and the moving speed of the exposure member 130 is fast, the exposure in the corresponding section may be shorter than that of other regions. On the contrary, when the moving speed of the exposure member 130 is slow, the exposure in the corresponding section may be more than other areas.

Therefore, the image processor 470 according to the present exemplary embodiment may adjust the image brightness corresponding to the moving speed of the image area for each of the plurality of image areas corresponding to the exposure period. For example, when an image is divided into A area, B area, and C area, the moving speed of the A area is the fastest, the B area has the average speed, and the moving speed of the C area is the lowest, the image processor 470. Can be calibrated to have a brightness value corresponding to the moving speed of the B area for the entire image, to have a brightness value higher than the B area for the A area, and to have a brightness value lower than the B area for the C area. have. In the above description, the image brightness is adjusted by dividing the image into three regions for easy explanation. However, in the implementation, the image may be divided into three or more regions, and the region may be divided by the number of pixels corresponding to the exposure direction. You can also distinguish.

In the above description, the image processing unit 470 divides the image into a plurality of areas and adjusts the brightness value for each of the divided areas. However, this is a case where the detection of the exposure speed is performed before the print command. When detection and correction of the brightness value are performed in real time, the brightness of the entire image may be corrected according to the detected exposure speed in response to the exposure speed.

The controller 480 controls the components of the display apparatus 400. In detail, when a user's print command is input, the controller 480 may display the display unit 420, the detector 460, and the image processor so that a print job in the portable image forming apparatus may be performed on the image currently being displayed. 470 may be controlled.

When the print command is input, the controller 480 may control the display unit 420 to display an image on the display area of the display unit 420 corresponding to the detected exposure area.

When the print command is input, the controller 480 may adjust the brightness of the display 420 to have a predetermined brightness or more, and control the image processor to adjust the brightness of the image on the adjusted brightness of the display. Such an operation may be performed when the display unit 420 is implemented as an AMOLED.

When the print command is input, the controller 480 displays the image at a refresh rate that is different from a preset first value (a value in a general operation state) of the display unit 420. Can be controlled. In detail, the controller 480 may control the display 420 to display an image at a refresh rate corresponding to the exposure speed of the portable image forming apparatus.

More specifically, a general display device displays an image with a predetermined refresh rate in displaying an image. However, when the moving speed of the exposure member 130 is fast, a black line as shown in the left image a of FIG. 65 may be generated by the intersection of the moving speed of the exposure member 130 and the refresh rate. Accordingly, the manufacturer of the display apparatus 400 or the manufacturer of the portable image forming apparatus may determine a refresh rate value at which black lines are not generated according to the moving speeds of the various exposure members 130 by various experiments. Accordingly, the controller 480 may control the display unit 420 to display an image at a refresh rate corresponding to information previously stored in the storage unit 440 or the detected speed of the exposure member 130 (exposure speed). . On the other hand, when the display unit 420 displays an image with a refresh rate of 0, there is no room for generating black as described above, and the controller 480 causes the display unit 420 to have a refresh rate of 0. It can be used to display an image in a state.

The controller 480 may change the refresh rate to the original state when the print command is input and the preset time elapses. In the present exemplary embodiment, the refresh rate is changed when a predetermined time elapses. However, in the implementation, the refresh rate may be changed when a touch corresponding to the arrangement of the plurality of touch sensors is no longer detected. That is, when the portable image forming apparatus and the display apparatus are detected to be spaced apart from each other, the refresh rate may be changed to the original state.

As described above, the display apparatus 400 according to the present exemplary embodiment may perform operations such as image quality correction even in a print job using a portable image forming apparatus that exposes an instant film by using an exposure member that is manually driven. In particular, it is possible to correct a deterioration in image quality that may occur as the exposure member is operated manually. In addition, it is possible to correct the deterioration in image quality due to the intersection of the exposure speed of the exposure member and the refresh line.

61 and 62 illustrate examples of a user interface window that may be displayed on the display of FIG. 60.

Referring to FIG. 61, the user interface window 500 includes a brightness adjustment area 510, an exposure adjustment area 520, an image display area 530, an image selection area 530, a display area 550, and a print area ( 560, a reset region 570.

The brightness adjusting area 510 is an area for receiving a brightness to be applied to the selected image from the user. When the user selects the brightness adjustment area, the brightness of the displayed image may be adjusted by reflecting the selected brightness value.

The exposure adjustment area 520 is an area for selecting how many seconds the display for printing the selected image is to be continued. For example, after displaying an image as shown in FIG. 62 according to a user's print command, if a time set by the user has elapsed, the screen as shown in FIG. 61 may be restored.

The image selection area 530 is an area for displaying the currently selected image.

The image selection area 530 is an area in which an image before the image currently being displayed is selected from among the images described in the storage unit 440 or a display of an image after the image currently being displayed is selected.

The display area 550 is an area for receiving a user command for displaying a list of printable images.

The print area 560 is an area for receiving a print command for the image selected in the image selection area 530. When the user selects the print area 560, the image selected in the image selection area 530 is adjusted as shown in FIG. 62 so that the image can be printed on the portable image forming apparatus without deterioration of the image quality.

The reset area 570 is an area in which a user receives a command for initializing a pre-selected option.

FIG. 63 is a diagram showing the form of a portable image forming apparatus according to the fifth embodiment.

Referring to FIG. 63, the portable image forming apparatus 100 ′ according to the fifth embodiment includes a plurality of touch sensors 116 in addition to the configuration of the portable image forming apparatus 100 according to the first embodiment. Except that a plurality of touch sensors 116 are additionally provided with the same configuration as the first embodiment, description of other configurations will be omitted.

The plurality of touch sensors 116 are disposed around the incident window 113e. Therefore, when the portable image forming apparatus 100 ′ and the display apparatus 400 are attached as shown in FIG. 21 for printing, the touch screen of the display apparatus 400 may detect positions of the plurality of touch sensors 116. In this case, the size of the incident window 113e may be detected. For example, if the display apparatus 400 knows that the touch sensor is disposed 5 mm apart from the incident window 113e, the display apparatus 400 knows the size of the incident window by subtracting 10 mm from the detected distance between the two positions. Can be. In addition, if the plurality of touch sensors are disposed in an area where the position of the incident window 113e is known (for example, at a vertex of the incident window), the display apparatus 400 may determine the position of the incident window through the detected position. Will be able to figure out.

In addition, the plurality of touch sensors 116 may be arranged in a form that can grasp the arrangement direction of the display apparatus with respect to the instant printing apparatus. For example, when the display device is attached as shown in FIG. 21, one touch is sensed at the top of the display device 400 and two touches are sensed at the bottom. If the upper and lower parts of the display device are in contact with each other, two touches are sensed on the upper part of the touch screen, and one touch is sensed on the lower part of the touch screen. Accordingly, the display apparatus 400 may recognize an attachment form between the display apparatus 400 and the portable image forming apparatus 100 ′ through the arrangement of the touch sensor 116, and does not correspond to the manufacturer's intention. In this case, an error message (voice) may be output or rotated 180 degrees of the displayed image.

The plurality of touch sensors 116 may be used to determine whether the display device is correctly disposed on the instant printing device. For example, if the two devices are correct, if the upper touch position should be at a certain coordinate and the currently detected touch position is not at the specific coordinate, the display device may output that it is not correctly positioned at this time. If placed in position, it can be notified that it has been properly deployed.

64 is a diagram showing the form of a portable image forming apparatus according to the sixth embodiment.

Referring to FIG. 64, the portable image forming apparatus 100 ″ according to the sixth embodiment may have a touch that is moved in correspondence with the movement of the exposure member 130 in addition to the configuration of the portable image forming apparatus 100 according to the first embodiment. The sensor 117 is provided, except that the touch sensor 117 is additionally provided, and has the same configuration as that of the first embodiment, and descriptions of other configurations are omitted.

The touch sensor 117 is disposed around the incident window 113e and is moved corresponding to the movement of the exposure member 130. Therefore, when the portable image forming apparatus 100 ″ and the display apparatus 400 are attached as shown in FIG. 21 for printing, the touch screen of the display apparatus 400 may sense the position of the touch sensor 117. In this case, when the user manually drives the exposure member 130, the display apparatus 400 may detect the movement of the touch sensor, and thereby detect the movement speed (exposure speed) of the exposure member 130.

FIG. 65 is a view illustrating a printing state of an instant film according to a brightness value when the display unit 420 is implemented with AMOLED. Specifically, the image on the left is a print image when the brightness of the AMLED is set to 71%, and the image on the right is a print image when the brightness of the AMLED is explained by 72%.

AMOLED operates linearly with respect to luminance brightness in the high luminance region, and operates by applying AID (AMOLED Impulsive Driving) function in the medium to low luminance region, while AID fixed interval (Of duty 40%) and low luminance is applied in the medium luminance. In the drawing region (110 cd or less), a change in brightness is implemented by applying a variable AID section (off duty variable).

As the AMOLED has a different driving method for each luminance section, the display unit 420 is controlled to operate the AMOLED in a high luminance region, that is, at a brightness value of 72% or more, in order to perform a print job in the portable image forming apparatus. It is desirable to.

However, when the brightness value of the display device 420 increases, the print output also increases in brightness value. Therefore, in order to correct this, an ND filter may be provided between the exposure member 130 and the display unit 420 as shown in FIG. 49, thereby reducing the amount of light transmitted to the portable image forming apparatus 100.

Alternatively, the amount of light in the portable image forming apparatus 100 may be the same, so as to darken the brightness of the image to correspond to the adjusted brightness of the display unit 420.

67 is a flowchart for explaining a print control method according to the first embodiment.

Referring to FIG. 67, first, an exposure speed of a “portable image forming apparatus for exposing to an instant film using light of a screen displayed on a display unit” is detected (S6710). Specifically, the exposure speed may be detected according to the position of the touch sensor of the portable image forming apparatus on the touch screen. Such a sensing method has been described above with reference to FIG. 64, and thus redundant description thereof will be omitted. In some embodiments, the exposure position may be photographed to detect the exposure speed through a change in the exposure position in the photographed image. Here, the portable image forming apparatus is a printing apparatus that exposes the instant film using screen light displayed on the display unit 420.

In operation S6720, the brightness of the image to be displayed is adjusted by the display unit according to the detected exposure speed to display the adjusted image. Specifically, the brightness value of the image may be adjusted such that the same amount of light is provided to the instant film for each exposure position of the portable image forming apparatus.

As described above, the display control method according to the first exemplary embodiment may correct a deterioration in image quality that may occur when the exposure member 130 is manually operated. The display control method of FIG. 50 may be executed on the display device having the configuration of FIG. 60 or may be executed on the display device having other configurations.

In addition, the display control method as described above may be implemented as a program (or application) containing an executable algorithm that can be executed on a computer, the program being stored in a non-transitory computer readable medium. Can be provided.

The non-transitory readable medium refers to a medium that stores data semi-permanently and is readable by a device, not a medium storing data for a short time such as a register, a cache, a memory, and the like. Specifically, the various applications or programs described above may be stored and provided in a non-transitory readable medium such as a CD, a DVD, a hard disk, a Blu-ray disk, a USB, a memory card, a ROM, or the like.

68 is a flowchart for explaining a print control method according to the second embodiment.

Referring to FIG. 68, an image is displayed at a predetermined refresh rate in operation S6810.

And a print command is input (S6820). The printing command may be a selection of a predetermined area on the touch screen, or may be performed by sensing a touch sensor included in the portable image forming apparatus by contact with the portable image forming apparatus. On the other hand, it has been described above that the print command is input by using a connection on the touch screen of the touch sensor, but in implementation, a lid switch may be used in addition to the touch sensor.

When the print command is input, the image is adjusted and displayed at a refresh rate different from the preset refresh rate (S6830). In detail, the refresh rate of the display may be varied so that the image is displayed at the refresh rate corresponding to the exposure speed of the portable image forming apparatus.

The display control method according to the second embodiment as described above can correct the deterioration in image quality due to the intersection of the exposure speed of the exposure member and the refresh line. The display control method of FIG. 68 may be executed on the display device having the configuration of FIG. 60 or may be executed on the display device having other configurations.

In addition, the display control method as described above may be implemented as a program (or application) containing an executable algorithm that can be executed on a computer, the program being stored in a non-transitory computer readable medium. Can be provided.
