[0002]

2. Description of the Related Art Conventionally, there is known a photo original image pickup apparatus for picking up a photographic image of a photographic original with an image pickup apparatus having a low resolving power (usually 400,000 pixels or less).

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to further improve a photographic document imaging device for capturing a photographic image of a photographic document.

[0004]

Means for solving the problems of the present invention will be described below for each individual means together with the problems and the effects.

[Claim 1] To capture a color image by the pixel shift method, if the procedure is such that the image of one color is captured by pixel shift and then the image of another color is captured, pixel shift is performed. There is a problem that the positional relationship of the formed image formation points is not accurately reproduced, and there is a high possibility that each color will shift. In addition, there is a problem in that pixel shifting must be performed for a plurality of colors. It is an object of the present invention to accurately reproduce the positional relationship of image forming points where pixel shifting is performed between the respective colors, and to obtain a high quality image with a smaller number of pixel shifting. Therefore, in a photographic document imaging device that captures a photographic image of a photographic document for a plurality of colors, an imaging unit including a large number of pixels arranged in a predetermined array capable of capturing any of the plurality of colors; A pixel shifter that shifts the image formation position of the photographic image of the photographic document by a distance shorter than the pixel interval of the image pickup means, and a color filter that determines the image pickup color of the image pickup means from a plurality of color filters. Filter selecting means, wherein the filter selecting means sequentially changes a color filter that determines an image capturing color of the image capturing means for the plurality of colors, and the image capturing means captures a photographic image of a photographic original of the image capturing color. Capturing an image, and shifting the image forming position of the photographic image of the photographic document of the image capturing unit by a distance shorter than the pixel interval of the image capturing unit by the pixel shifting unit, Photographic original imaging apparatus characterized by sequentially repeating alternately. ], An image of a plurality of colors is picked up for each pixel shift, so that the amount of pixel shift is reduced by that much, and the positional relationship of the image formation points where pixel shift is performed may shift between the colors. High quality images can be obtained without any.

Here, the image pickup by the pixel shift method means
That is, the images are sequentially captured while shifting the image forming position by a distance shorter than the pixel interval of the photographic image capturing means. of course,
Even if images are sequentially captured while being shifted by (an integer multiple of the pixel interval) + (distance shorter than the pixel interval), the same effect can be obtained except for the image capturing end portion. The image forming position of the photographic image is displaced by a distance shorter than the pixel interval of the image pickup means ”. The integer here is
It is effective if it is smaller than the number of pixels in the shifting direction, but it is 1/2 times or less, usually 1/10 times or less, especially 1
/ 100 times or less is preferable. The following method may be used to shift the image forming position. First, there is a method of shifting the position of the image pickup means itself. Second, there is a method in which an image pickup lens means and a parallel plate glass are provided in front of the image pickup means, and the parallel plate glass is tilted to shift the image forming position of the image pickup lens means. Third, there is a method in which a mirror is provided in front of the image pickup means and the angle of the mirror is shifted to shift the image forming position. This pixel shift method is preferable because it can perform high-quality imaging with high resolution and high reproducibility even with an inexpensive imaging device.

The image pickup means capable of picking up an image of any of a plurality of colors means that the image pickup means is sensitive to any of a plurality of colors and can pick up an image.

[Claim 2] When a photographic image with a large number of pixels is picked up with a small amount of shifting by the pixel shifting method, the resolution is high, but it takes a long time. Further, if a large amount of shift is used to capture a photographic image with a low pixel count, the resolution becomes low for a short time. Therefore, a single pixel shift type imaging device has never been used for both a high-resolution but long-time application and a short-time but low-resolution application. An object of the present invention is an image pickup apparatus of one pixel shift type, which has a high resolution but may take a long time, and a short time but may have a low resolution. Is to provide a switchable switch. Therefore, "the image pickup means composed of a large number of pixels arranged in a predetermined array for picking up a photographic image of a photographic document, and the image forming position of the photographic image of the photographic document of the image pickup means are separated by a distance shorter than the pixel interval of the image pickup means. A photographic original image pickup device comprising: a pixel shifting unit for shifting; and a shift amount of an image forming position by the pixel shifting unit can be changed. ], The shift amount of the image forming position by the pixel shift means can be changed. Therefore, in one pixel shift type imaging device, the resolution is high but the application may take a long time and the resolution may be short but low. It can be used for both purposes.

[Claim 3] In a photographic document imaging device that images a photographic image of a photographic document for a plurality of colors after determining the exposure, if the exposure is determined by image data of a plurality of colors, it takes time to determine the exposure. However, if the exposure is determined by the image data of one color, the exposure will not be appropriate if the photo document has a color feria. An object of the present invention is to be able to determine an appropriate exposure with a single imaging. Therefore,

Appropriate image information can be obtained, exposure conditions can be made appropriate when capturing images for a plurality of colors, and it does not take time to determine exposure.

[Item 5] As described in Item 4, the image pickup using the pixel shift does not significantly change the appropriate exposure condition from the start to the end of the image pickup, but the accuracy is higher. Exposure control may be required. An object of the present invention is to make it possible to perform both exposure control that performs an appropriate exposure condition with one measurement for exposure and exposure control with higher accuracy.

Therefore, the color light cut filter holding means rotation position detecting means and the color light cut filter holding means rotation driving means play the role of filter changing means.

The cross-sectional shape of the filter is shown in FIG. In the upper part of FIG. 5, the filter has an ordinary disk shape, but is arranged with an inclination of an angle θ with respect to a plane perpendicular to the optical axis. Naturally, the filter support 70
1 and the holding plate 702 are also arranged to be inclined. This allows
Since a plane parallel to the filter and the imaging lens means or the solid-state image sensor is not formed, the reflected light is reflected outside the optical path, and it is effective that internal reflection occurs between the filter and the imaging lens means or the solid-state image sensor. It can be prevented.

As a modification, what is shown on the lower side of FIG. 5 is that the filter has a convex shape on the photographic document side of the imaging optical axis. As a result, no parallel surface is formed with the filter and the image pickup lens means or the solid-state image sensor, so that the reflected light is reflected outside the optical path, and internal reflection occurs between the filter and the image pickup lens means or the solid-state image sensor. It can be effectively prevented. Since the filter is not inclined with respect to the plane perpendicular to the optical axis, the filter supporting portion 701 and the pressing plate 702
Is not leaning.

The solid-state image pickup device 71 has a spectral sensitivity to any of the three primary colors B: G: R. Further, since the solid-state image sensor 71 usually has spectral sensitivity to infrared rays or ultraviolet rays, it is necessary to cut these when controlling exposure with a neutral color. Also,
Since the three primary colors of B: G: R have different sensitivities, it is preferable to have a filter for adjusting these. Therefore, in order to adjust the difference in sensitivity between the three primary colors of B: G: R of the solid-state image sensor 71 by cutting infrared rays or ultraviolet rays, an exposure determination filter indicated by N in FIG. 4 is inserted in the image pickup optical axis. Exposure control is performed when In addition, the present example and Examples 2 to be described later
In 5, the solid-state image pickup device may be a MOS type image pickup device or the like, but it is preferable to use a CCD from the viewpoints of low cost and the effect of the present invention. Hereinafter, I having an electronic shutter function
The T-CCD or the FIT-CCD will be described in the description. However, for example, the exposure condition may be changed without changing the shutter time of the electronic shutter, and the aperture of the lens may be changed accordingly. I don't mind.

The photographic image pickup means 70 is held by the image pickup means frame 91 held by the frame. The solid-state image sensor 71 is held by a disk-shaped solid-state image sensor frame 97. And
The solid-state image sensor electronic board 79 is disposed on the back side of the solid-state image sensor 71. The electronic substrate 79 for the solid-state image pickup device is connected to the A / D conversion section 172 by a wire for transmitting analog image information as described later. Further, it is connected to the imaging control unit 171 by a control interface. A black light-shielding tube 96 made of metal and having a black inner surface is provided so as to surround the circumferential portion of the circular solid-state imaging device frame 97. A light shielding lid 95 is provided so as to fit with the light shielding tube 96. The imaging means holding plate 94 is
The solid-state imaging device 71 side of the imaging lens means 72 is kept light-tight,
A circular solid-state image sensor frame 97 is held via a pillar. Blackout tube
Only the light passing through the imaging lens means 72 is incident on the solid-state imaging device 71 by the 96, the light shielding lid 95, and the imaging means holding plate 94. The image pickup device frame 91 fixedly holds the image pickup device holding plate 94. Further, the color light cut filter holding means 92 for holding the color light cut filter holding means 73, the gear 75, the drive motor 74, the mark detection means 76 and the like is shown in FIG. It can be adjusted back and forth in the direction shown, and after adjusting
It is fixedly held by 93.

Pixel shifting is performed by a parallel flat glass plate 7 such as BK7 provided on the solid-state image pickup device frame 97 via a plurality of piezoelectric elements 8. The parallel flat plate glass plate 7 is provided on the imaging lens means 72 side of the solid-state imaging device 71. The pixel shift control unit 174 applies a suitable voltage to the plurality of piezoelectric elements 8 holding the parallel flat glass plate 7 to expand a part of the piezoelectric elements 8 and slightly change the inclination of the parallel flat glass plate 7. , The imaging position is slightly deviated.

The pixel shift need not be performed by the parallel flat plate glass plate 7 provided via the piezoelectric element 8, but the parallel flat plate glass plate 7 may be slightly tilted by mechanical means, or the piezoelectric element may be used. Alternatively, the solid-state imaging device itself may be displaced by mechanical means.

The parallel flat glass plate 7 is a flat glass plate whose both surfaces have higher flatness and higher parallelism than a normal flat glass plate. The glass material may be a normal glass material, but especially when it is a high refractive index and low dispersion glass, chromatic aberration can be prevented and a high quality image can be obtained. In this case, it is necessary to control the inclination accuracy of the glass plate more precisely than that of a normal glass material.

FIG. 6 is a diagram for explaining the pixel shift. Normally, when the solid image pickup element is in focus exactly, the image information of the scattered areas is picked up. That is, normally, the solid-state imaging device cannot be provided so that the individual light receiving portions (photodiodes) are in contact with each other. Therefore, as shown in FIG. Yes.) Are scattered.
Therefore, as shown in FIG. 6A, the image information of the area surrounded by the square of the object to be imaged is imaged. Also,
A solid-state image sensor having a large number of pixels becomes considerably expensive due to manufacturing restrictions and the like. Therefore, in order to increase the resolution while keeping the number of pixels of the solid-state image sensor, and to capture the image information between the discrete areas peculiar to the solid-state image sensor,
Imaging is performed by shifting the image forming position by a distance shorter than the pixel interval. This is called pixel shifting.

FIG. 6B is a diagram showing an example in which the image forming position is slightly shifted in the lateral direction to pick up an image. An area A1 surrounded by a solid line square is imaged by the first imaging, an area A2 surrounded by a double line square is imaged by the second imaging, and a dotted square is imaged by the third imaging. The enclosed area A3 is imaged, the area A4 is imaged in the fourth imaging, the area A5 is imaged in the fifth imaging, and the area A6 is imaged in the sixth imaging. FIG. 6C is a diagram showing an example of capturing an image by slightly shifting the image forming position in the vertical direction. An area A1 surrounded by a solid line square is imaged in the first imaging, and an area A7 surrounded by a double line square is imaged in the seventh imaging. In the thirteenth imaging, the area A13 surrounded by the dotted rectangle is imaged. The eighth to twelfth and the fourteenth to eighteenth imaging are performed by slightly shifting the image forming positions in both the vertical and horizontal directions. In this way, it is possible to pick up an image with a high pixel count, that is, with a high resolution, which is 18 times the number of pixels unique to the solid-state image sensor. For example, if the number of unique pixels of the solid-state image sensor is 400,000, high-resolution imaging of 7.2 million pixels can be performed.

In the above-mentioned pixel shift, the operator operates the operation unit 120 to input the shift amount of the image forming position by the pixel shift, and the control unit 110 causes the image pickup to be performed based on the input instruction. It is changed by controlling the pixel shift control unit 174 of the image pickup unit 70 and the image pickup characteristic correction image processing unit 175 through the control unit 171. Therefore, even if the image is not shifted at all (in this case, 400,000 pixels, the imaging time is
It becomes 1/18. ), The above-mentioned pixel shift interval is tripled, and the vertical and horizontal density of the image is ⅓ each (in this case, 800,000 pixels, but the imaging time is 1/9). By halving, the image can be captured with double the vertical and horizontal densities (in this case, the imaging time is four times, but the image quality is 28.4 million pixels).

Has a function of correcting the reproduction characteristic of the reproducing CRT 80, which is a reproducing means, and sequentially transmits the corrected signals to the D / A converter 83.

Next, the flow of image signals will be described. A captured image signal is sent from the photographic image capturing means 70 to the A / D converter 172. The captured image signal is converted into a digital captured image signal by the A / D converter 172, sent to the image transfer memory 173, and temporarily stored. Then, the images are sequentially sent from the image transfer memory 173 to the picked-up image storage means 176 for each one-time shooting with pixel shift. The digital captured image signal is temporarily stored in the captured image storage means 176. When one frame of digital captured image signal is newly stored in the captured image storage means 176, the new one frame of digital captured image signal is captured by the image capturing characteristic correction image processing means 17.
In step 5, the image pickup characteristic of the photographic image pickup means is corrected and stored in the pickup image storage means 176. Further, during focus adjustment, the image pickup image signal of the solid-state image pickup device 71 is changed by the A / D converter 172 while the focus position of the image pickup lens means 72 is changed step by step.
Is converted into a digital picked-up image signal and sequentially input to the image pickup characteristic correction image processing means 175, and the focus position having the most focus is determined. Then, it is sent to the image pickup control section 171 and the focus position of the image pickup lens means 72 is adjusted to the focus position where the focus is the most. During exposure adjustment, the captured image signal is converted into a digital captured image signal by the A / D conversion unit 172 and sequentially input to the image capturing characteristic correction image processing unit 175, the image capturing light amount distribution is checked, and the appropriate solid state image sensor 71 Calculate the accumulation time (electronic shutter time). Then, it is sent to the imaging control unit 171 and the accumulation time of the solid-state imaging device 71 is adjusted.

Then, based on the transfer control signal from the control unit 110, the electronic image information stored in the captured image storage means 176 is transferred to and stored in the image memory 180. Further, it is sent to the electronic image information recording means 150 and recorded on the mini magnetic disk 151 which is a portable image recording medium. Further, based on an instruction input by the operator operating the operation unit 120, the control unit 110 appropriately selects the image processing unit from the image memory 180.
The electronic image information whose imaging characteristic is corrected by 160 is read, and the electronic image information reading means 150 records on the mini-magnetic disk 151 on which the electronic image information to be reproduced or synthesized and reproduced is recorded. The recorded electronic image information is read and sent to the image processing unit 160. The image processing unit 160 performs image processing, performs image processing for synthesizing some read electronic image information, and stores it in the image memory 180 according to an instruction from the control unit 110.
Further, based on an instruction input by the operator operating the operation unit 120, the control unit 110 causes the image memory 180 to read the electronic image information, and the electronic image information is sent to the image display monitor 190 and is then displayed on the image display monitor 190. The image is displayed.

Then, the image memory 180 is reproduced in the CRT 80 for reproduction.

At the timing when the data is accumulated and reproduced by the reproduction CRT 80, the electronic image information is read from the image memory 180 based on the transfer control signal from the control unit 110 and transferred to the reproduction characteristic correction image processing means 86. The transferred electronic image information is sequentially subjected to correction of the reproduction characteristics of the reproduction CRT 80 by the reproduction characteristic correction image processing means 86, and is sequentially sent to the D / A conversion section 83.

Further, the amount by which the image-forming position is shifted by pixel shifting and the imaging exposure condition once determined once are set to the first control mode in which the imaging exposure condition is continuously used or the imaging exposure condition is performed every time the pixel is shifted. The operator can input the control mode by operating the operation unit 120. Then, based on the input instruction, the control unit 110 controls the image pickup unit 70 through the image pickup control unit 171.

FIG. 8 shows an example of the control flow. Start with S01. The power is turned on in S02. The device is initialized in S03. Further, here, the operator operates whether or not the amount of shift of the image forming position by the pixel shift and the imaging exposure condition are performed every time the pixel shift is performed (that is, whether the first control mode or the second control mode of item 5). Operate section 120 to input. Then, the result input by the operator operating the operation unit 120 is set in the control unit 110. In S04, it is detected whether the color film is set on the negative carrier 30. If it is not set in the negative carrier 30, that state is maintained. If the negative carrier 30 is set, the process proceeds to S05, and the light source 11 is put on standby. Apply a voltage that does not actually cause light emission. Further, the double-sided mirror 41 is inserted in the exposure optical path. In S06, it is determined whether or not the exposure light source has reached a steady temperature and a predetermined time required for the vibration of the printing paper conveying means to subside has elapsed. If it has not passed, it will be maintained. If the required predetermined time has elapsed, the process proceeds to S07.

At S07, the controller 110 drives the motors for the color film drive rollers 33 and 34. As a result, the color film is conveyed in the forward direction until the next image frame is detected. In step S08, the exposure light source 11 is turned on.

In S09, the frame image of the color film set on the negative carrier 30 is picked up while shifting the pixels, and is stored in the picked-up image storage means 176. Figure 9 for S09
Alternatively, it consists of the subroutine shown in FIG.
If the control unit 110 is set not to perform the imaging exposure condition each time the pixel shift is performed, that is, after the imaging exposure condition is first determined, the imaging exposure condition is not re-determined and In the case of using the imaging exposure condition [first control mode of item 5], the subroutine shown in FIG. 9 is entered. If the control unit 110 is set to obtain the imaging exposure condition each time the pixel shift is performed [second control mode of item 5], the subroutine shown in FIG. 10 is entered.

The subroutine shown in FIG. 9 will be described below. After the start S31, in S32, the color light cut filter holding means 73 is rotated to set the exposure determination filter N of FIG. 4 on the incident light side of the imaging lens means 72. S

At 9, the B color light cut filter is set on the incident light side of the imaging lens means 72. In step S40, the solid-state image pickup device 71 of the photographic image pickup means 70 picks up the B color of the photographic image of the photographic original. Then, the captured B-color image is converted into a digital image by the A / D conversion unit 172 and stored in the image transfer memory 173. In S41, the digital image signal stored in the image transfer memory 173 is stored in the captured image storage means 176 through the data bus in the photographic image capturing section 170. In S42, it is determined whether the pixel shift is completed. If not finished, S
Under the control of the pixel shift control unit 174 at 43, the predetermined pixel shift is performed as described above. Then, the process proceeds to S35. If it has ended, this subroutine is ended in S44 and the process proceeds to the next S10.

The subroutine shown in FIG. 10 will be described below. After the start S51, in S52, the color light cut filter holding means 73 is rotated to set the exposure determining filter N of FIG. 4 on the incident light side of the imaging lens means 72. S
At 53, the imaging controller 171 adjusts the focus of the imaging lens means 72 based on the imaging information from the solid-state imaging device 79. S54
Then, based on the image information from the solid-state image sensor 79, the exposure adjustment for adjusting the electronic shutter time of the solid-state image sensor 79 is performed. In S55, the R color light cut filter is set to the image pickup lens means.
Set it on the incident light side of 72. In S56, a photographic image capturing means

At 9, the B color light cut filter is set on the incident light side of the imaging lens means 72. In step S60, the solid-state image pickup device 71 of the photographic image pickup means 70 picks up the B color of the photographic image of the photographic original. Then, the captured B-color image is converted into a digital image by the A / D conversion unit 172 and stored in the image transfer memory 173. In S61, the digital image signal stored in the image transfer memory 173 is stored in the image memory 180 through the data bus 145 in the photographic image capturing section 170. In S62, it is determined whether the pixel shift is completed. If it is not completed, the predetermined pixel shift is performed as described above by the control of the pixel shift control unit 174 in S63. Then, the process proceeds to S52. If it has ended, this subroutine is ended in S64, and the next S10
Proceed to.

In step S10, the digital image signal stored in the captured image storage means 176 is read out and transferred to the captured image characteristic correction image processing means 175 through the data bus 145. The image pickup characteristic correction image processing unit 175 corrects the image pickup characteristic of the photographic image pickup unit 70 on the transferred digital image signal. The digital image signal whose imaging characteristics of the photographic image capturing means 70 have been corrected is sent to the captured image storage means 176 via the data bus 145 and stored therein. Then, the electronic image information in which the imaging characteristic of the photographic image capturing means 70 is corrected, which is stored in the captured image storage means 176, is read out and stored in the image memory 180 via the SCSI interface 141. In step S11, the electronic image information stored in the image memory 180 and having the image pickup characteristic of the photographic image pickup means 70 corrected is read out, and the electronic image information recording means 150 is read through the data bus 140.
Sent to the mini magnetic disk 151 which is a portable image recording medium
To record. In S12, it is determined whether or not all the frame images of the color film set on the negative carrier 30 have been captured. If not finished, the process proceeds to S07. If it is completed, the process proceeds to S13. In this way, a plurality of frame images of the color film are sequentially captured one by one and stored.

In step S13, the operator looks at the display of the operation display unit 130 while instructing the images of the respective frames to judge, correct, combine the images, and instruct the display of another image. Operate and input the instruction. Then, according to the content of the instruction, the control unit 110 reads out the electronic image information from the image memory 180 and reads out the electronic image information recorded in the mini magnetic disk 151 set in the electronic image information recording means 150. By selecting that, the electronic image information is read from the image memory 180, or the electronic image information recorded on the mini magnetic disk 151 set in the electronic image information recording means 150 is read. Then, based on the read electronic image information, the image processing unit 160

Return to

When the process is completed, the process proceeds to S16. In S16, the printing paper is conveyed to the printing position. In S17, the automatic printing apparatus B prints or reproduces as a printer output. In S18, it is judged whether the printing and the reproduction are finished. If printing and reproduction have not been completed, the process proceeds to S16. When printing and reproduction are complete,
Proceed to S04. Here, in printing, according to the contents of the output image, the control unit 110 sequentially conveys the photographic paper to the printing position one frame at a time, with the double-sided mirror retracted from the exposure optical path, and moves the color film in the reverse direction. It is continuously repeated to carry (S16), illuminate the frame image of the color film and print it on the printing paper (S17).
