BACKGROUND OF THE INVENTION
  The present inventionFilm carrierIn particular, it is possible to detect whether the conveyed photographic film is a negative film or a reversal film.Film carrierRelated.
[0002]
[Prior art]
An image forming apparatus that forms an image by printing an image recorded on a photographic film on a photosensitive material such as photographic paper is provided with a film carrier for transporting the photographic film. When an analog printer that directly irradiates an image with light whose color balance has been adjusted and prints the transmitted image on photographic paper is used, the photographic film is conveyed by a film carrier and printed onto the photographic paper. In addition, when using a digital printer that reads an image recorded on photographic film, converts the read image into digital image data, and prints the image on photographic paper using the converted image data, the film carrier uses a photographic film. Feed the film and read the image.
[0003]
Photographic films include negative films on which negative images are recorded and reversal films on which positive images are recorded. Conventionally, a film carrier dedicated to transporting negative films and a film carrier dedicated to transporting reversal films are provided, and photographic films are transported by dedicated film carriers, respectively.
[0004]
[Problems to be solved by the invention]
However, since the operator conventionally determines whether the photographic film is a negative film or a reversal film, it takes time and effort to select a film carrier corresponding to the photographic film to be transported. There is a problem that it is difficult to improve.
[0005]
  The present invention has been made to solve the above problems, and the photographic film can be used as both a negative film and a reversal film.Film carrierThe purpose is to provide.
[0006]
[Means for Solving the Problems]
  In order to achieve the above object, the invention described in claim 1 is applied as a part of a digital lab system. In order to obtain image data by reading an image from a photographic film on which an image is recorded by a reading means, Positioning the film at a reading position by the reading means;The photographic film has a barcode optically recorded at both ends in the width direction,A film carrier comprising a bar code sensor that reads the density of the bar portion of the bar code and the density of the film base or bar code space while being conveyed along the length direction of the photographic film,Based on the film base density information including the bar density of the bar code and the space between the bars determined based on the signal from the bar code sensor,It has a detecting means for detecting whether the photographic film is a negative film or a reversal film.
[0007]
  According to the first aspect of the present invention, the film carrier is provided with detecting means for detecting whether the photographic film to be conveyed is a negative film or a reversal film.
  As the detecting means, a bar code sensor that reads a bar code optically recorded at both ends in the width direction of the photographic film can be applied, and the bar code sensor discriminated based on a signal from the bar code sensor. Based on the film base density information including the bar density and the space between the bars, it can be detected whether the photographic film is a negative film or a reversal film.
[0008]
The photographic film has barcode recording areas where barcodes are recorded at both ends in the width direction of the photographic film. In the case of a negative film, the density of the portion corresponding to the barcode bar is high, and the reversal In the case of film, the density of the portion corresponding to the bar of the barcode is low. Therefore, an optical sensor that optically detects the barcode recording area along the length direction of the photographic film can be used as the detecting means. Since the optical sensor outputs a signal according to the density of the photographic film, the level of the signal output when the barcode bar recorded on the photographic film is detected depends on the space of the film base or barcode bar. If it is lower than the level of the signal output when (the same density as the film base) is detected, it can be determined that the photographic film is a negative film. On the other hand, if the level of the signal output when the bar of the barcode is detected is higher than the level of the signal output when the film base or the like is detected, it is determined that the photographic film is a reversal film. Can do.
[0009]
Thus, since it can be determined whether the photographic film transported by the film carrier is a negative film or a reversal film, it is not necessary to provide a dedicated film carrier corresponding to each film, and the same film carrier can be used for any photographic film. Can also be used.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, the digital laboratory system 10 according to the present embodiment will be described first.
[0016]
(Schematic configuration of the entire system)
FIG. 1 shows a schematic configuration of a digital lab system 10 according to the present embodiment, and FIG. 2 shows an appearance of the digital lab system 10. The digital laboratory system 10 includes a line CCD scanner 12, an image processing unit 16, a laser printer unit 18, and a processor unit 20. As shown in FIG. 2, the line CCD scanner 12 and the image processing unit 16 are provided in the input unit 26, and the laser printer unit 18 and the processor unit 20 are provided in the output unit 28.
[0017]
The line CCD scanner 12 is for reading a film image recorded on a photographic film such as a negative film or a reversal film. For example, 135 size photographic film, 110 size photographic film, photographic film with a transparent magnetic layer (240 size photographic film: so-called APS film), 120 size and 220 size (Broni size) photographic film The recorded film image can be read. The line CCD scanner 12 includes a line CCD 74 (see FIG. 3) in which three rows of R, G, and B photometry sensors are arranged. The line CCD 74 reads a film image, and R, G, B3. Output color image data.
[0018]
The image processing unit 16 receives the image data (scanned image data) output from the line CCD scanner 12, and the image data obtained by photographing with a digital camera, and a document other than a film image (for example, a reflective document). The image data obtained by reading the image with a scanner, the image data generated by a computer, etc. (hereinafter collectively referred to as file image data) are input from the outside (for example, via a storage medium such as a memory card). Or can be input from another information processing device via a communication line).
[0019]
The image processing unit 16 performs image processing such as various corrections on the input image data, and outputs the image data to the laser printer unit 18 as recording image data. Further, the image processing unit 16 outputs the image data subjected to the image processing to the outside as an image file (for example, outputs it to a storage medium such as a memory card or transmits it to another information processing apparatus via a communication line). Etc.) is also possible.
[0020]
The laser printer unit 18 includes a laser light source that emits R, G, and B laser beams. The laser beam that is modulated according to the recording image data input from the image processing unit 16 is applied to the photographic paper. An image is recorded on photographic paper by scanning exposure. The processor unit 20 performs color development, bleach-fixing, water washing, and drying on the photographic paper on which an image is recorded by scanning exposure in the laser printer unit 18. As a result, an image is formed on the photographic paper.
[0021]
(Configuration of line CCD scanner)
As shown in FIG. 3, the optical system of the line CCD scanner 12 includes a halogen lamp, a metal halide lamp, and the like. The light source 64 emits light to the photographic film 22 and the light applied to the photographic film 22 is diffused light. A light diffusion box 66 is disposed in order along the optical axis L on the light emission side of the light source 64.
[0022]
The photographic film 22 is conveyed by a film carrier 14 (see FIG. 6, not shown in FIG. 3) disposed on the light exit side of the light diffusion box 66 so that the screen of the film image is perpendicular to the optical axis.
[0023]
Further, C (cyan), M (magenta), and Y (yellow) dimming filters 70C, 70M, and 70Y are sequentially arranged between the light source 64 and the light diffusion box 66 along the optical axis L of the emitted light. Has been. The dimming filters 70C, 70M, and 70Y are configured to be independently movable, and in the optical path in consideration of the balance of the amount of each component color light emitted from the light source 64, the sensitivity of the line CCD 74 to each component color light, and the like. The amount of insertion into can be adjusted. As a result, the received light amounts of the three colors R, G, and B in the line CCD 74 are adjusted.
[0024]
On the opposite side of the photographic film 22 from the light source 64, a lens unit 72 that forms an image of light transmitted through the film image and a line CCD 74 are arranged in this order along the optical axis L. In FIG. 3, only a single lens is shown as the lens unit 72. However, the lens unit 72 may be a zoom lens composed of a plurality of lenses. The line CCD 74 is provided with three lines of CCD cell lines that are arranged in a line so that the CCD cells are orthogonal to the conveyance direction of the photographic film 22 (the direction of arrow A shown in FIG. 3). This is a three-line color CCD in which any of R, G, and B color separation filters is attached on the incident side, and the light receiving surface is disposed so as to coincide with the image forming point position of the lens unit 72. Accordingly, main scanning for film reading is performed in the CCD cell arrangement direction, and sub-scanning for film image reading is performed by conveying the photographic film 22. In the line CCD 74, since three lines (CCD cell rows) are sequentially arranged at a predetermined interval along the conveyance direction of the photographic film 22, each component of R, G, and B in the same pixel is arranged. There is a time difference in color detection timing. This time difference is corrected by accumulating pixel data in the line memory and delaying the line memory output in consideration of the time difference.
[0025]
FIG. 4 shows a schematic configuration of the electrical system of the line CCD scanner 12. The line CCD scanner 12 includes a microprocessor 30 that controls the entire line CCD scanner 12. The microprocessor 30 is connected to a RAM 34 (for example, SRAM) and a ROM 36 (for example, a ROM capable of rewriting stored contents) via a bus 32, and is connected to a motor driver 38. The motor driver 38 has a filter. A drive motor 40 is connected. The filter drive motor 40 can slide the dimming filters 70C, 70M, and 70Y independently.
[0026]
The microprocessor 30 turns on and off the light source 64 in conjunction with turning on and off a power switch (not shown). Further, when the microprocessor 30 reads a film image (photometry) by the line CCD 74, the light control filters 70C, 70M, and 70Y are independently slid by the filter drive motor 40, and the amount of light incident on the line CCD 74 is obtained. Is adjusted for each component color light.
[0027]
Further, the motor driver 38 moves the zoom unit 42 and the entire lens unit 72 by changing the zoom magnification of the lens unit 72 by relatively moving the positions of the plurality of lenses of the lens unit 72. A lens drive motor 44 is connected to move the image forming point positions 72 along the optical axis. The microprocessor 30 uses the zoom drive motor 42 to change the zoom magnification of the lens unit 72 to a desired magnification according to the size of the film image, whether or not to perform trimming, and the like.
[0028]
On the other hand, a timing generator 46 is connected to the line CCD 74. The timing generator 46 generates various timing signals (clock signals) for operating a line CCD 74, an analog-digital converter (hereinafter referred to as an A / D converter) 50 described later, and the like. Accordingly, the film image is read by the line CCD 74 based on the timing signal output from the timing generator 46.
[0029]
The signal output terminal of the line CCD 74 is connected to the input terminal of the A / D converter 50 via the amplifier 48. The signal output from the line CCD 74 is amplified by the amplifier 48 and converted into digital data by the A / D converter 50.
[0030]
An output terminal of the A / D converter 50 is connected to an interface (I / F) circuit 54 via a correlated double sampling circuit (CDS) 52. The CDS 52 samples feedthrough data indicating the level of the feedthrough signal and pixel data indicating the level of the pixel signal, and subtracts the feedthrough data from the pixel data for each pixel. Then, the calculation result (pixel data accurately corresponding to the amount of charge accumulated in each CCD cell) is sequentially output to the image processing unit 16 as scan image data via the I / F circuit 54.
[0031]
Since the line CCD 74 outputs R, G, and B photometric signals, three signal processing systems including an amplifier 48, an A / D converter 50, and a CDS 52 are provided. R, G, B image data is output as scanned image data.
[0032]
The motor driver 38 is connected to a shutter drive motor 56 that opens and closes a shutter (not shown) provided between the line CCD 74 and the lens unit 72. The dark output of the line CCD 74 is corrected by the image processing unit 16 at the subsequent stage, but the dark output level can be obtained by the microprocessor 30 closing the shutter when the film image is not read. .
[0033]
(Configuration of image processing unit)
Next, the configuration of the image processing unit 16 will be described with reference to FIG. The image processing unit 16 is provided with a line scanner correction unit 122 corresponding to the line CCD scanner 12. The line scanner correction unit 122 corresponds to the R, G, and B image data output in parallel from the line CCD scanner 12, and performs signal processing including a dark correction circuit 124, a defective pixel correction unit 128, and a light correction circuit 130. Three systems are provided.
[0034]
The dark correction circuit 124 receives data (data indicating the dark output level of each cell of the sensing unit of the line CCD 74) input from the line CCD scanner 12 in a state where the light incident side of the line CCD 74 is shielded by the shutter. Each pixel is stored and corrected by subtracting the dark output level of the cell corresponding to each pixel from the scan image data input from the line CCD scanner 12.
[0035]
Further, the photoelectric conversion characteristics of the line CCD 74 also vary from cell to cell. The bright correction circuit 130 at the subsequent stage of the defective pixel correction unit 128 reads the adjustment frame image with the line CCD 74 while the line CCD scanner 12 is set with the adjustment frame image having a constant density on the entire screen. For each cell based on the image data of the adjustment frame image input from the line CCD scanner 12 (the variation in density for each pixel represented by this image data is caused by the variation in photoelectric conversion characteristics of each cell). A gain is determined, and the image data of the frame image to be read input from the line CCD scanner 12 is corrected for each pixel in accordance with the gain determined for each cell.
[0036]
On the other hand, in the image data of the adjustment frame image, if the density of a specific pixel is significantly different from the density of other pixels, the cell corresponding to the specific pixel of the line CCD 74 has some abnormality, The specific pixel can be determined as a defective pixel. The defective pixel correction unit 128 stores the address of the defective pixel based on the image data of the adjustment frame image, and the defective pixel data among the image data of the frame image to be read input from the line CCD scanner 12. Generates new data by interpolating from the data of surrounding pixels.
[0037]
Further, since the line CCD 74 has three lines (CCD cell rows) arranged in order along the conveyance direction of the photographic film 22 with a predetermined interval, each component of R, G, B from the line CCD scanner 12 is arranged. There is a time difference in the timing of starting the output of color image data. The line scanner correction unit 122 delays the output timing of the image data with a different delay time for each component color so that the R, G, and B image data of the same pixel is simultaneously output on the frame image.
[0038]
The output end of the line scanner correction unit 122 is connected to the input end of the selector 132, and the image data output from the correction unit 122 is input to the selector 132. The input terminal of the selector 132 is also connected to the data output terminal of the input / output controller 134, and file image data input from the outside is input to the selector 132 from the input / output controller 134. The output terminal of the selector 132 is connected to the input / output controller 134 and the data input terminals of the image processor units 136A and 136B, respectively. The selector 132 can selectively output the input image data to each of the input / output controller 134 and the image processor units 136A and 136B.
[0039]
The image processor unit 136A includes a memory controller 138, an image processor 140, and three frame memories 142A, 142B, and 142C. Each of the frame memories 142A, 142B, and 142C has a capacity capable of storing image data of a frame image for one frame, and the image data input from the selector 132 is stored in one of the three frame memories 142. However, the memory controller 138 stores the image data in the frame memory 142 so that the pixel data of the input image data is stored in the storage area of the frame memory 142 in a certain order. Control the address.
[0040]
The image processor 140 takes in the image data stored in the frame memory 142, and performs gradation conversion, color conversion, hypertone processing for compressing the gradation of the ultra-low frequency luminance component of the image, and sharpness is enhanced while suppressing grain. Various image processing such as hyper sharpness processing is performed. The processing conditions for the image processing are automatically calculated by an auto setup engine 144 (described later), and image processing is performed according to the calculated processing conditions. The image processor 140 is connected to the input / output controller 134, and the image data subjected to image processing is temporarily stored in the frame memory 142 and then output to the input / output controller 134 at a predetermined timing. Note that the image processor unit 136B has the same configuration as the image processor unit 136A described above, and a description thereof will be omitted.
[0041]
By the way, in this embodiment, each frame image is read twice with different resolutions in the line CCD scanner 12. In the first reading at a relatively low resolution (hereinafter referred to as pre-scan), even if the density of the frame image is extremely low (for example, an overexposed negative image in a negative film), the charge accumulated in the line CCD 74 is saturated. The frame image is read under the reading conditions determined so as not to occur (the amount of light for each of the R, G, and B wavelength ranges of the light irradiating the photographic film, the charge accumulation time of the CCD). Image data (pre-scan image data) obtained by this pre-scan is input from the selector 132 to the input / output controller 134 and further output to the auto setup engine 144 connected to the input / output controller 134.
[0042]
The auto setup engine 144 includes a CPU 146, a RAM 148 (for example, DRAM), a ROM 150 (for example, a ROM whose contents can be rewritten), and an input / output port 152, which are connected to each other via a bus 154.
[0043]
The auto setup engine 144 reads a second relatively high resolution by the line CCD scanner 12 based on pre-scan image data of a plurality of frame images input from the input / output controller 134 (hereinafter referred to as fine scan). The image processing processing conditions for the image data (fine scan image data) obtained by (1) are calculated, and the calculated processing conditions are output to the image processor 140 of the image processor unit 136. In the calculation of the processing conditions of the image processing, it is determined whether or not there are a plurality of frame images obtained by photographing a similar scene from the exposure amount at the time of photographing, the type of photographing light source and other feature amounts, and a plurality of images obtained by photographing the similar scene are determined. When there are two frame images, the processing conditions of the image processing for the fine scan image data of these frame images are determined to be the same or approximate.
[0044]
The optimum processing conditions for image processing also vary depending on whether the image data after image processing is used for recording an image on photographic paper in the laser printer unit 18 or output to the outside. Since the image processing unit 16 includes two image processor units 136A and 136B, for example, when the image data is used for recording an image on photographic paper and is output to the outside, the auto setup engine 144 is used. Calculates the optimum processing conditions for each application and outputs them to the image processor units 136A and 136B. As a result, the image processors 136A and 136B perform image processing on the same fine scan image data under different processing conditions.
[0045]
Further, the auto setup engine 144 is for image recording that defines a gray balance or the like when an image is recorded on photographic paper by the laser printer unit 18 based on pre-scan image data of a frame image input from the input / output controller 134. The parameters are calculated and output simultaneously when outputting the recording image data (described later) to the laser printer unit 18. In addition, the auto setup engine 144 calculates image processing conditions for file image data input from outside in the same manner as described above.
[0046]
The input / output controller 134 is connected to the laser printer unit 18 via the I / F circuit 156. When the image data after image processing is used for recording an image on photographic paper, the image data subjected to image processing by the image processor unit 136 is recorded from the input / output controller 134 via the I / F circuit 156. The data is output to the laser printer unit 18. The auto setup engine 144 is connected to the personal computer 158. When image data after image processing is output to the outside as an image file, the image data subjected to image processing by the image processor unit 136 is output from the input / output controller 134 to the personal computer 158 via the auto setup engine 144. Is done.
[0047]
The personal computer 158 includes a CPU 160, a memory 162, a display 164, and a keyboard 166 (see also FIG. 2), a hard disk 168, a CD-ROM driver 170, a transport control unit 172, an expansion slot 174, and an image compression / decompression unit 176. These are connected to each other via a bus 178. The conveyance control unit 172 is connected to the film carrier 14 and controls conveyance of the photographic film 22 by the film carrier 14. When an APS film is set on the film carrier 14, information (for example, an image recording size) read by the film carrier 14 from the magnetic layer of the APS film is input.
[0048]
Also, a driver (not shown) for reading / writing data from / to a storage medium such as a memory card and a communication control device for communicating with other information processing devices are connected via a personal computer 158 via an expansion slot 174. Connected to. When image data for output to the outside is input from the input / output controller 134, the image data is output to the outside (the driver, the communication control device, etc.) as an image file via the expansion slot 174. When file image data is input from the outside via the expansion slot 174, the input file image data is output to the input / output controller 134 via the auto setup engine 144. In this case, the input / output controller 134 outputs the input file image data to the selector 132.
[0049]
The image processing unit 16 outputs prescanned image data and the like to the personal computer 158, and displays an image obtained by displaying the frame image read by the line CCD scanner 12 on the display 164 or recording it on photographic paper. When the image is estimated and displayed on the display 164 and an image correction or the like is instructed by the operator via the keyboard 166, it can be reflected in the processing conditions of the image processing.
[0050]
(Structure of film carrier)
Here, the structure of the film carrier 14 for conveying the 135 size photographic film 22 will be described with reference to FIG. As shown in FIG. 7, the 135 size photographic film 22 has a perforation perforation area where perforations 58 are perforated at predetermined intervals on both ends in the width direction, and a bar code recording area where bar codes 60 are recorded. Is formed. One of the barcode recording areas is recorded with an FNS code representing information such as a frame number by a barcode of one track, and the other is recorded with a DX code representing information of a film type and the like by a barcode of two tracks. . The photographic film 22 in FIG. 7 shows a negative film, and the bar 60A of the barcode 60 is recorded at a density higher than the density of the film base 23 of the photographic film 22. On the other hand, in the case of the reversal film (see FIG. 10) 22S, the recording is reversed with the negative film image. For this reason, the bar 60A of the barcode 60 recorded on the reversal film has a density lower than that of the film base 23S (details will be described later).
[0051]
As shown in FIG. 6, the film carrier 14 includes a substantially box-shaped casing 302 including an upper lid 302 </ b> A and a base 302 </ b> B, and various members related to film conveyance described later in the casing 302. Is housed. A film insertion port 304 for inserting the photographic film 22 is provided at one end of the housing 302, and a film storage unit 306 for storing the photographic film 22 is provided at the other end. Yes. The film accommodating portion 306 is provided with a substantially cylindrical guide plate 307 that guides the photographic film 22 along the inner peripheral surface of the film accommodating portion 306. Accordingly, the photographic film 22 inserted from the film insertion port 304 and conveyed along the film conveyance path is accommodated while being wound around the film accommodating portion 306 by being guided by the guide plate 307.
[0052]
The casing 302 is configured to release the coupling between the upper lid 302A and the base 302B by operating the release switch 308, and is provided on the opposite side of the release switch 308 in the state where the engagement is released. The upper lid 302A can be rotated substantially upward about a hinge (not shown).
[0053]
Inside the housing 302, an end detection sensor 310 that detects the front end of the photographic film 22 along the film conveyance path from the film insertion port 304 to the film storage unit 306, a conveyance roller pair 312, and the photographic film 22. A dust removing roller 314 that removes dust from the surface of the photographic film, a bar code sensor 316 that optically detects a bar code 37 recorded at both ends in the width direction of the photographic film 22, a pair of conveying rollers 318, and the photographic film 22 are irradiated. A light shielding device 320 that shields a range corresponding to the size of the film image in the slit light and a pair of conveying rollers 322 are sequentially arranged.
[0054]
The end detection sensor 310 has a contact ring 310A that is in contact with the photographic film 22 at one end rotatably attached thereto, a crank 310B that rotates about a bent portion as a rotation axis, and a light emitting element that detects passage of the other end of the crank 310B. And a photointerrupter 310C configured by combining with a light receiving element. When the photographic film 22 is conveyed along the film conveyance path and the leading edge of the photographic film 22 comes into contact with the contact wheel 310A of the end detection sensor 310, the crank 310B rotates. As the crank 310B rotates, the other end of the crank 310B passes between the light emitting element and the light receiving element of the photo interrupter 310C. Thereby, it can be detected that the tip of the photographic film 22 has passed through the film conveyance path. Further, after the other end of the crank 310B is detected by the photo interrupter 310C, it can be detected that the rear end of the photographic film 22 has passed through the film conveyance path when the other end of the crank 310B is not detected. That is, the front and rear ends of the photographic film 22 can be detected by the end detection sensor 310. In the case where the photographic film 22 is a reversal film, the density of the portion covered with light at the front end of the film is lowered and the density of the unexposed portion at the rear end of the film is increased. If it is a typical sensor, it is difficult to detect the tip of the photographic film 22 or the like. Therefore, the end detection sensor 310 has a mechanical configuration.
[0055]
The bar code sensor 316 is provided with three sensor portions 316A, 316B, and 316C. The sensor units 316A and 316C detect the barcode recording area of the photographic film 22 along the length direction of the photographic film 22. As a result, a signal having a level corresponding to the density of the barcode recording area is output. 9A and 10A are enlarged views of a part of the photographic film 22 (part IX surrounded by an imaginary line shown in FIG. 7). The photographic film 22 shown in FIG. 9A is a negative film. In this case, the signals shown in FIG. 9B are output from the sensor units 316A and 316C (signal characteristics 24). That is, since the density of the bar 60A portion of the barcode 60 is higher than the density of the film base 23, the level of the signal output when the bar 60A of the barcode 60 is detected is the same as that of the film base 23 or film base 23. It becomes lower than the level of the signal output when the density space 60B is detected. When the photographic film inserted in the film carrier 14 is a reversal film 23S as shown in FIG. 10A, the signals shown in FIG. 10B are output from the sensor units 316A and 316C. (Signal characteristic 24S). That is, since the density of the bar 60A of the barcode 60 is lower than the density of the film base 23S, the level of the signal output when the bar 60A of the barcode 60 is detected has the same density as that of the film base 23S or the film base 23S. It becomes higher than the level of the signal output when the space 60B is detected.
[0056]
The sensor unit 316 </ b> B of the barcode sensor 316 detects the vicinity of the central portion in the width direction of the photographic film 22 along the length direction of the photographic film 22. Thereby, the edge of the film image recorded on the photographic film 22 can be detected. That is, when the negative film is conveyed in the direction of arrow A shown in FIG. 6, the signal level output from the sensor unit 316B is lower than the predetermined level (the level when the film base 23 is detected). Sometimes it can be determined that the leading edge of the film image has been detected, and then it can be determined that the trailing edge has been detected when the signal level has increased to a predetermined level. In the case of a reversal film, the reverse is true.
[0057]
In each of the conveying roller pairs 312, 318, and 322, driving rollers 312A, 318A, and 322A are positioned below the photographic film 22 in FIG. 6, and driven rollers 312B, 318B, and 322B are positioned above the photographic film 22, respectively. ing. The conveyance roller pairs 318 and 322 are provided on both sides of the position where the line CCD 74 reads the photographic film 22. In addition, a pulse motor 324 that is a driving force source of the driving rollers 312A, 318A, and 322A is installed inside the housing 302, and a pulley 326 is attached to a driving shaft of the pulse motor 324. An endless belt 328 is wound around the pulley 326, and the endless belt 328 is also wound around a pulley 330 attached to the rotating shaft of the driving roller 322A. Accordingly, the driving force of the pulse motor 324 is transmitted to the driving roller 322A via the pulley 326, the endless belt 328, and the pulley 330.
[0058]
A pulley 332 is attached to the rotation shaft of the driving roller 322A, and an endless belt 334 is wound around the pulley 332. The endless belt 334 is also wound around a pulley 336 attached to the rotation shaft of the driving roller 318A, and the driving force of the pulse motor 324 is also transmitted to the driving roller 318A via the pulley 332, the endless belt 334, and the pulley 336. Is done. A pulley 338 is attached to the rotation shaft of the drive roller 318A, and an endless belt 340 is wound around the pulley. The endless belt 340 is also wound around a pulley 342 attached to the rotation shaft of the driving roller 312A, and the driving force of the pulse motor 324 is also transmitted to the driving roller 312A via the pulley 338, the endless belt 340, and the pulley 342. Is done.
[0059]
Furthermore, motors 344, 346, and 348 are installed in the housing 302. A disc 350 is eccentrically attached to the drive shaft of the motor 344, and one end of a connecting member 352 for moving the driven roller 322B up and down rotates at a predetermined position near the outer edge of the disc 350. It is pivotally supported. The connecting member 352 is rotatably supported around a support shaft 354, and a driven roller 322B is rotatably supported on the other end side of the connecting member 352. Therefore, when the disk 350 is slightly rotated in the direction of arrow C by the driving force of the motor 344, the upper portion of the connecting member 352 (the shaft support portion of the driven roller 322B) is slightly rotated in the direction of arrow D around the support shaft 354, and is driven. The roller 322B is slightly separated from the driving roller 322A.
[0060]
Similarly, a disc 356 is attached to the drive shaft of the motor 348 in an eccentric state, and one end of a connecting member 358 for moving the driven roller 318B up and down at a predetermined position near the outer edge of the disc 356. Is fixed. The connecting member 358 is rotatably supported around a support shaft 360, and a driven roller 318B is rotatably supported on the other end side of the connecting member 358. Therefore, when the disk 356 is slightly rotated in the direction of arrow E by the driving force of the motor 348, the upper portion of the coupling member 358 (the shaft support portion of the driven roller 318B) is slightly rotated in the direction of arrow F around the support shaft 360, and is driven. The roller 318B is slightly separated from the driving roller 318A.
[0061]
Incidentally, a substantially central portion between the pair of conveying rollers 318 and 322 is a reading position of the photographic film 22, and a slit hole 302C is formed in the upper lid 302A immediately above the reading position. The slit hole 302C extends in a direction orthogonal to the conveyance direction of the photographic film 22 (the direction of arrow A shown in FIG. 4). Although not shown, the base 302B and the film conveyance path are also provided with slit holes similar to the slit holes 302C through which light emitted from the light source 64 passes just below the reading position. As shown in FIG. 4, the photographic film 22 conveyed by the film carrier 14 is irradiated with light from below at the reading position, and the light transmitted through the photographic film 22 is transmitted through the lens unit 72 positioned above the film carrier 14. Through the line CCD 74.
Further, as shown in FIG. 8, the shading device 320 described above shields a range corresponding to the size of each film image among the light irradiated to the photographic film 22 passing through the reading position. A pair of film transport paths 22 are provided (only the light blocking device 320 on the near side is shown in FIG. 6). As shown in FIG. 8, the light shielding device 320 includes a motor 346, gears 362 and 364, and a cam-shaped light shielding plate 366 attached to the rotation shaft of the gear 364. When the film image is read, the light shielding plate 366 is rotated to the position indicated by the solid line by the driving force of the motor 346 as shown in FIG. When a standard size (so-called L size) film image is read, the light shielding plate 366 is rotated to the position of the dotted line in FIG. In this way, by shielding the area that is not to be read, it is possible to prevent the accumulated charge from being saturated in the line CCD 74 (see FIG. 3).
[0062]
(Operation of this embodiment)
Next, the operation of the embodiment of the present invention will be described with reference to the flowchart shown in FIG. When the photographic film 22 is read by the line CCD scanner 12 of the digital laboratory system 10, the operator inserts the photographic film 22 into a film insertion port 304 formed in the film carrier 14. When the photographic film 22 is inserted and the leading edge of the photographic film 22 is detected by the edge detection sensor 310, the pulse motor 324 is driven. During the prescan, the driving force of the pulse motor 324 is transmitted to the driving rollers 312A, 318A, and 322A and rotates in the direction of arrow G shown in FIG. Accordingly, the photographic film 22 is conveyed in the direction of arrow A by the conveying roller pairs 312, 318, and 322.
[0063]
When the photographic film 22 is conveyed, in step 100, it is determined whether or not the leading edge of the film image recorded on the photographic film 22 has reached the image reading position. This can be determined based on the level of the signal output from the sensor unit 316B provided in the barcode sensor 316. That is, the level of the signal output from the sensor unit 316B is lower than a predetermined level when the film is a negative film (level when the space 60B of the film base 23 or the barcode 60 is detected), and higher when the film is a reversal film. From time to time, it is determined that the leading edge of the film image has reached the image reading position of the line CCD scanner 12 when the photographic film 22 is conveyed for a predetermined time.
[0064]
If it is determined in step 100 that the film image has reached the image reading position of the line CCD scanner 12, a pre-scan is performed in step 102. That is, the light emitted from the light source 64 and passing through the photographic film 22 passes through the slit hole 302C and enters the line CCD 74 via the lens unit 72. In the next step 104, it is determined whether or not the pre-scan for all film images recorded on the photographic film 22 has been completed. The end of the pre-scan is determined that the pre-scan for all the film images recorded on the photographic film 22 has been completed when a predetermined time has elapsed after the trailing edge of the photographic film 22 is detected by the edge detection sensor 310. Can do. If it is determined in step 104 that pre-scanning for all film images recorded on the photographic film 22 has been completed, the process proceeds to step 106, and based on pre-scan image data obtained by pre-scanning. Set the scanning conditions for fine scanning.
[0065]
When the setting of reading conditions and the like is completed in step 106, the conveyance of the photographic film 22 is once stopped, the pulse motor 324 is driven again, and the driving rollers 312A, 318A, and 322A are rotated in the direction of arrow H shown in FIG. Accordingly, the photographic film 22 is conveyed in the arrow B direction by the conveying roller pairs 312, 318, and 322.
[0066]
When the photographic film 22 is conveyed in the direction of arrow B, it is determined in step 108 whether or not the trailing edge of the film image recorded on the photographic film 22 has reached the image reading position. If it is determined in step 108 that the trailing edge of the film image recorded on the photographic film 22 has reached the image reading position, in step 110, a fine scan is performed based on the reading conditions set in step 106. In the next step 112, it is determined whether or not fine scanning has been completed for all film images recorded on the photographic film 22. The end of the fine scan can be determined in substantially the same manner as the end of the pre-scan, and the fine scan for all the film images recorded on the photographic film 22 when the end detection sensor 310 detects the leading edge of the photographic film 22 is completed. judge.
[0067]
Subsequently, in step 114, it is determined whether the photographic film 22 conveyed by the film carrier 14 is a negative film or a reversal film. This can be determined based on the level of a signal output from any of the sensor units 316A and 316C of the barcode sensor 316. In this embodiment, the determination is made based on the level of the signal output from the sensor unit 316A of the barcode sensor 316. As described above, when the negative film barcode 60 is detected, the signal characteristic 24 of FIG. 9B is obtained, and when the reversal film barcode 60 is detected, FIG. 10B is obtained. The signal characteristic 24S shown is obtained. When the output when the photographic film is inserted into the film carrier 14 from the leading end and detected is the signal characteristic 24 shown in FIG. 9B, the photographic film 22 conveyed by the film carrier 14 is negative. Judged to be film. On the other hand, when the signal characteristic 24S shown in FIG. 10B is obtained, it is determined that the photographic film conveyed by the film carrier 14 is the reversal film 22S.
[0068]
If it is determined in step 114 that the photographic film 22 conveyed by the film carrier 14 is a negative film, the process proceeds to step 116. In step 116, the fine scan image data read in step 110 is inverted by the image processing unit 16, and the inverted fine scan image data is output to the output unit 28 (laser printer unit 18) as recording image data. On the other hand, if it is determined in step 114 that the photographic film 22 is a reversal film, the fine scan image data read in step 110 is output to the output unit 28 as image data for recording.
[0069]
Thus, regardless of whether the photographic film 22 is a negative film or a reversal film, recording image data for recording a positive image on photographic paper is input to the output unit 28. Therefore, the laser printer unit 18 and the processor unit 20 provided in the output unit 28 can automatically record a positive image regardless of whether the photographic film 22 is a negative film or a reversal film. In addition, you may make it form a negative image from a negative film and a reversal film as needed.
[0070]
As described above, since the photographic film 22 transported by the film carrier 14 is detected and processed as a negative film or a reversal film, the same film carrier 14 is applied to any photographic film 22. Can also be used.
[0071]
In this embodiment, the photographic film 22 is formed on the basis of a signal output by detecting the bar code recording area in which the bar code (FNS code) 60 of one track is recorded by the sensor unit 316A of the bar code sensor 316. Although the example which detects whether it is a negative film or a reversal film was demonstrated, it is not limited to this. For example, the detection may be performed based on a signal output from the sensor unit 316C of the barcode sensor 316 that detects a barcode recording area in which a barcode (DX code) of two tracks is recorded.
[0072]
In the present embodiment, an example in which the edge of the film image is detected by the sensor unit 316B of the barcode sensor 316 and the start of pre-scanning and fine scanning at the image reading position is instructed has been described. It is not a thing. For example, the sensor units 316A and 316C of the bar code sensor 316 detect the perforations 58 formed at predetermined intervals at both ends in the width direction of the photographic film 22, count the number, and press the perforation 58 based on the count value. It may be configured to instruct the start of can and fine scan.
[0073]
Furthermore, a notch 62 (see FIG. 7) may be formed on the photographic film 22 at a position corresponding to the film image. In this case, a part of the barcode 60 recorded in the barcode recording area is lost and the barcode 60 cannot be read accurately, and information such as the frame number and film type is printed on the back side of the photographic paper. There are cases where it cannot be done. Therefore, when the notch 62 is formed, the frame number 68 (see FIG. 7) displayed at the position corresponding to the film image of the photographic film 22 is read by the line CCD 74 and printed on the back surface of the photographic paper. Good.
[0074]
In addition, the 135 size photographic film 22 is taken out from the cartridge and inserted into the film carrier 14 to be conveyed. For this reason, when the photographic film 22 is conveyed, the leading end side of the photographic film 22 is in a state where the rear end side of what is accommodated in the film accommodating portion 306 is exposed to the outside of the film carrier 14. At this time, when an operator or the like touches the photographic film 22, a transport load fluctuation occurs in the photographic film 22, and the transport jitter may exceed an allowable value. Therefore, when the 135 size photographic film 22 is transported by the film carrier 14, as shown in FIGS. 12A and 12B, the photographic film 22 taken out from the cartridge is once in a shape substantially similar to that of the cartridge. The intermediate cartridge 90 may be wound into the intermediate cartridge 90 and the intermediate cartridge 90 may be loaded into the film insertion opening 304 of the film carrier 14.
[0075]
Further, when the piece film 22B of the 135 size photographic film 22 is transported by the film carrier 14, the leader 92 may be joined to the piece film 22B by the splice tape 96 and transported as shown in FIG. Good. At this time, a take-up roller 94 is disposed in, for example, the film accommodating portion 306 of the film carrier 14, and the take-up roller 94 is rotated at a constant speed to take up the piece film 22B to which the leader 92 is bonded. To do. Thereby, the conveyance jitter which arises when pinching the perforation perforation area | region with the unevenness | corrugation of the photographic film 22 between several conveyance roller pairs, and conveying can be prevented. When the photographic film is taken up by rotating the take-up roller 94 at a constant speed, the take-up diameter is gradually increased and the film transport speed is increased. For this reason, it is preferable to gradually reduce the rotation speed of the winding roller 94 so that the film conveyance speed becomes constant.
[0076]
Moreover, although the film carrier 14 which conveys the 135 size photographic film 22 was demonstrated in this Embodiment, it is applicable also to APS film 22A. As shown in FIG. 14, the APS film 22A is a perforation in which a bar code recording area in which a bar code 78 is recorded is formed at one end in the width direction, and a perforation 80 is formed at the other end in the width direction. A drilling region is formed. The perforations 80 are formed in the vicinity of the leading edge and the trailing edge in each film image recorded on the APS film 22A. In addition, magnetic recording layers 82 on which various types of information relating to film images and the like are magnetically recorded are formed at both ends in the width direction of the APS film 22A.
[0077]
The film carrier 14A that transports the APS film 22A has a slightly different configuration from the film carrier 14 that transports the 135-size photographic film 22, and will be described with reference to FIGS. Detailed description of the components that are substantially the same as those of the film carrier 14 for transporting the 135-size photographic film 22 described above will be omitted. Further, the film carrier 14A is built in a substantially box-shaped housing like the film carrier 14 for transporting the 135 size photographic film 22 described above, but the housing is not shown in FIGS. Yes.
[0078]
In the film carrier 14A shown in FIGS. 15 to 17, the cartridge 402 containing the APS film 22A is set at a predetermined position, and various kinds of conveyance described later are performed along the direction in which the APS film 22A is pulled out from the set cartridge 402. A roller pair is arranged. In the following, the direction in which the APS film 22A in the direction of arrow J shown in FIG. 15 is pulled out is referred to as the drawing direction, and the direction in which the APS film 22A in the direction of arrow K is rewound into the cartridge 402 is stored.
[0079]
A pair of conveying rollers 404, a dust removal roller 406, and a dust removal roller 408 for removing dust from the surface of the magnetic recording layer 82 along a pulling direction from a predetermined position where the cartridge 402 is set (both ends in the width direction of the APS film 22A). The magnetic information read / write unit 410 (APS) includes a magnetic head 410R that reads magnetic information from the magnetic recording layer 82 and a magnetic head 410W that writes magnetic information to the magnetic recording layer 82, respectively. A pair corresponding to both ends in the width direction of the film 22A), a perforation sensor 412 for detecting the perforation 80 and the bar code 78, a pair of conveying rollers 414, and warping along the width direction of the APS film 22A to correct the warp in the APS film 22A. Film image scanning position (actually APS fill 22A, a film support member 416 for holding the surface of the APS film 22A so that the surface of the APS film 22A is flat, a pair of conveying rollers 418, 420, and a temporary winding portion 422 of the APS film 22A. Are arranged in order
The film support member 422 that corrects the warp along the width direction of the APS film 22A is formed by bending two flat plates into an arc shape and forming two bent plates having a convex shape on the lower side by about 0.8 mm. It is comprised across the gap. The two bent plates are provided with image reading slit holes 415 extending in the width direction of the APS film 22A. The film support member 422 shown in FIGS. 15 to 17 is formed in a convex shape on the lower side, but may be formed in a convex shape on the upper side. Further, the conveyance roller pairs 414 and 418 disposed with the film support member 416 interposed therebetween can be omitted.
[0080]
The perforation sensor 412 detects the perforation 80 and outputs a signal having a level corresponding to the density of the barcode recording area of the APS film 22A. At this time, when the APS film 22A inserted into the film carrier 14A is a negative film, the level of the signal output when the bar of the bar code 78 is detected is the bar space of the bar code 78 (film base It is lower than the level of the signal that is output when it is detected. On the other hand, in the case of the reversal film, the level of the signal output when the bar of the barcode 78 is detected is higher than the level of the signal output when the space of the barcode 78 is detected.
[0081]
The magnetic head 410R that reads magnetic information from the magnetic recording layer 82 is connected to a personal computer 158 via an amplifier 98 as shown in FIG. At this time, it is determined whether the APS film 22A is a negative film or a reversal film based on the signal output from the perforation sensor 412, and the gain of the amplifier 98 is adjusted based on the determination result. That is, when it is determined that the APS film 22A is a reversal film, the gain is adjusted by a factor of two. This is because the reversal film takes into account that the magnetic material forming the magnetic recording layer 82 is half that of the negative film and the output from the magnetic head 410R is half that for improving the image quality.
[0082]
The conveyance roller pairs 404, 414, 418, 420 are the same as the conveyance roller pairs 312, 318, 322 of the film carrier 14 described above, and the driving rollers 404A, 414A, 418A, 420A and the driven rollers 404B, 414B, 418B, 420B. It is constituted by.
[0083]
The film carrier 14A is provided with a motor 430 serving as a driving force source for the driving rollers 404A, 414A, 418A, and 420A. The driving shaft 432 of the motor 430, the driving shaft 432 of the conveying roller pair 414, and the conveying roller. The drive shaft 434 of the pair 414 is connected by a multi-stage transmission mechanism 440 configured to include a plurality of pulleys, endless belts, and the like having different diameters.
[0084]
Endless belts 452 and 454 are wound around the drive shaft 434 of the conveying roller pair 414. Of these, the endless belt 452 is driven by the driving shaft 456 of the conveying roller pair 404, and the endless belt 454 is driven by the driving shaft 458 of the conveying roller pair 418. Each is wrapped around. An endless belt 460 is wound around the drive shaft 458 of the transport roller pair 418, and the endless belt 460 is wound around the drive shaft 462 of the transport roller pair 420. As a result, the drive shaft 434 of the transport roller pair 414 is rotationally driven by the driving force of the motor 430, so that the drive shafts 456, 458, and 462 are also rotationally driven. Accordingly, the rotational speed of the drive shafts 456, 458, and 462 is also changed by changing the rotational speed of the drive shaft 434 of the conveying roller pair 414 by the multi-stage transmission mechanism 440 while keeping the rotational speed of the motor 430 constant. The transport speed of the APS film 22A can be changed.
[0085]
By the way, a substantially central portion between the pair of conveying rollers 414 and 418 is a scanning position of the APS film 22A, and an upper portion and a lower portion of the scanning position in the housing (not shown) of the film carrier 14A and the above-described film support. A slit hole 415 for scanning light is formed in the member 416. That is, the APS film 22A conveyed through the film carrier 14A is irradiated with scanning light from below at the scanning position as shown in FIG. 3, and the transmitted light is arranged above the film carrier 14A. Is configured to reach.
[0086]
Although not shown, there is also a film sending mechanism that pulls out the leading end of the APS film 22A from the cartridge 402 and automatically feeds it to the holding portion of the conveying roller pair 404 when the cartridge 402 is set at the position shown in FIG. Built in the film carrier 14A.
[0087]
Further, in the film carrier 14A, not only the APS film 22A accommodated in the cartridge 402 but also the strip film taken out from the cartridge 402 is inserted into the holding portion of the conveying roller pair 404 as indicated by an imaginary line in FIG. Thus, it is possible to transport the same route as described above.
[0088]
Furthermore, the film support member for correcting the warp in the width direction of the APS film 22A may be configured as shown in FIG. As shown in FIG. 18 (A), the film support member 86 is formed by bending the flat plate into a substantially U shape and further bending one end at a substantially right angle to form the film pressing portion 86A. It is arrange | positioned corresponding to the width direction both ends, and the Nangle glass 88 is inserted between them. The APS film 22A is warped and conveyed by the film pressing portion 86A of the film support member 86 (see FIG. 18B). Note that both end portions in the length direction of the film pressing portion 86A are formed in an arc shape, and the APS film 22A is easy to be inserted into the film support member 86. Further, the height dimension T shown in FIG. 18A of the film support member 86 is a dimension obtained by combining the thickness of the APS film 22A and the depth of field. The film support member for correcting the warp along the width direction of the photographic film can also be applied to the above-described film carrier 14 that conveys the 135-size photographic film 22.
[0089]
The 135 size photographic film 22 has the screen center of the film image coincided with the print center when the recorded film image is printed on photographic paper. On the other hand, when the APS film 22A is used to take a picture with a camera, the perforation 80 perforated in the APS film 22A has a predetermined time (1 / The center of the print is determined by carrying it for 2 frames). However, the recording position of the film image and the position of the perforation 80 may be shifted due to the accuracy of the camera. In this case, the print center determined based on the perforation 80 and the screen center of the actual film image are shifted. Accordingly, when a film image recorded on the APS film 22A is printed, the film image that can determine the screen center of the film image is read by a CCD scanner, and the film image is read using the read image data. Preferably, the center of the image is calculated so that the screen center of the film image coincides with the print center. For a film image in which the screen center of the film image cannot be determined, the screen center is determined based on the position of the perforation as described above.
[0090]
Furthermore, since the width dimension of the film conveyance path formed in the film carriers 14 and 14A and the width dimension of the photographic films 22 and 22A do not always coincide with each other, when the photographic films 22 and 22A convey the film conveyance path May meander. In the present embodiment, the film image recorded on the photographic films 22 and 22A is read by the line CCD scanner 12 in which R, G, B3 CCD cell rows are arranged. For this reason, when the photographic film 22 meanders at the image reading position, the color represented by the read image data is shifted from the actual color (so-called color shift occurs). In order to prevent this color misregistration, it is necessary to transport the photographic films 22 and 22A so as not to meander in the film transport path. Accordingly, as shown in FIG. 19A, in the vicinity of the image reading position where the slit holes 302C and 415 are formed, the photographic films 22 and 22A are moved toward one side in the width direction of the film conveyance path. This is because a pair of bearing rollers 76A and 76B are disposed across the image reading position, and one of the side surfaces of the film conveyance path is used as a reference surface 84, and the photographic films 22 and 22A are moved in the width direction by the bearing rollers 76A and 76B (FIG. 12). In the direction indicated by the arrow L). Accordingly, since the photographic films 22 and 22A are conveyed without meandering at the image reading position, color misregistration during image reading can be prevented.
[0091]
In addition, high quality finishing such as hypertone and hyper sharpness may be performed on photographic paper on which a film image is printed. When the high-quality finish print is returned to the customer, the customer thinks that the shooting has been successful, and may not notice the difference in finish due to the difference between the digital lab system 10 and the normal lab system. is there. For this reason, when high-quality finishing is performed, the content may be printed on the back side or the index print on the front side or the back side.
[0092]
In the above description, the example of determining whether the film is a negative film or a reversal film by detecting the barcode 60 recorded on the photographic films 22 and 22A has been described. However, the density of the film bases 23 and 23S is detected. You may make it determine by.
[0093]
【The invention's effect】
As described above, according to the present invention, since it is detected whether the photographic film is a negative film or a reversal film, any photographic film can be used as the same film carrier. Has an excellent effect.
[0094]
Further, since a print corresponding to at least one of the negative film and the reversal film is created based on the image data read by the reading means and the detection result by the film carrier detection means, the photographic film is a negative film or a reversal film. Regardless of whether it is a film, it has an excellent effect that a print can be automatically created.
