FIG. 3 illustrates a process circuit 203 of one embodiment.
Is shown. The R, G, and B output signals of the image pickup circuit 115 must be adjusted so that the output ratio becomes 1: 1: 1 when a white subject is picked up. However, since the color temperature varies depending on the illumination light source, if a white subject is imaged at different color temperatures, the output ratio of R, G, B changes, and the captured image deteriorates. Therefore, when a white subject is imaged, white balance control is performed so that the output ratio of R, G, B becomes 1: 1: 1 even if the color temperature changes. This process circuit 203 uses a color difference signal generated from a signal from a CCD as color temperature information, and uses the principle that the average value of a large number of screens or a screen for a long time is almost white, and an automatic white balance is performed. It is a circuit that performs. That is, the color difference signals (RY) and (BY) are respectively integrated to obtain a value corresponding to an average value over a long time on the screen, and gains of the color signals R and B are adjusted so that these values become zero.

FIG. 4 is a perspective view showing the appearance of one embodiment. The film image display device of one embodiment has a structure that can be divided into a camera unit 401 and a film feeding unit 402. The camera unit 401 is attachable to and detachable from the film feeding unit 402 as the main body of the apparatus, and is used to display an image of the film 102 loaded in the cartridge chamber 410 in the mounted state. Further, the camera unit 401 can be separated from the film feeding unit 402, and the camera unit 401 alone can display an image other than film. For example, it is possible to photograph a landscape or the like, or to project a print or paper. Camera unit 401 to film feeding unit 4
When mounted on 02, the electrical circuits of both units are connected by the connector 408.

Both units 401 and 402 have switches 403 to 409 included in the key group 123 of FIG. The camera unit 401 includes a power switch 403, a position selection switch 404, and a mode selection switch 40.
5, a correction item selection switch 406, and a correction value input switch 407. The position selection switch 404 is a switch for selecting the position of negative / positive / camera, and the position can be cyclically switched each time the switch 404 is pressed as shown in FIG.

The mode selection switch 405 has an auto 1 /
This is a switch for selecting the auto 2 / manual mode. In the auto 1 mode, the above-described auto white balance control is performed, and in the auto 2 mode, the white balance control is performed with a preset fixed value. In addition,
Automatic exposure (AE) control is performed in any of the auto modes. On the other hand, in the manual mode, brightness correction, color correction (R, B correction), contrast correction, and contour correction are possible. Note that, as shown in FIG. 16, there are modes that cannot be selected depending on the position. In the negative position,
All modes of auto 1, 2 and manual can be selected, and three modes can be cyclically switched each time the switch 405 is pressed as shown in FIG. 18 (a). In the positive position, only the auto 2 mode and the manual mode can be selected, and the auto 2 mode and the manual mode can be switched alternately each time the switch 405 is pressed as shown in FIG. 18B. Furthermore, in the camera position, only auto 1 and manual mode can be selected, and as shown in FIG.
Each time 05 is pressed, the auto 1 mode and the manual mode can be switched alternately.

FIG. 19 shows a change in mode when the position is changed while the position and the mode are selected. If the "Positive" position is selected while the "Negative" position and "Auto 1" mode are selected (shown as "Negative / Auto 1" in the figure), the Auto 1 mode cannot be selected for the positive, so the Auto 2 mode is automatically selected. The display switches to and becomes positive / auto 2. Also, if the "camera" position is selected in the negative / auto 1 state, the camera is in the camera / auto 1 state because the auto 1 mode can be selected. Similarly, when the position is changed from the negative / auto 2 state, the positive / auto 2 state, and the camera / auto 1 state, the mode is automatically selected according to FIG. When the "negative" position is selected in the positive / auto 2 state, the mode is selected according to the presence / absence of "without image correction" information magnetically recorded on the film 102. When the image is not corrected and the information is not recorded, the auto 1 mode is selected and the negative / auto 1 state is set as shown in (1). On the other hand, when the information is recorded without the image correction, the auto 2 mode is selected and the negative / auto 2 state is set as shown in (2).

Further, the change of the mode when the position is changed may be shown in FIG. In FIG. 20, (1) indicates that the information is not recorded without image correction, (2) indicates that the information is recorded without image correction, and (3) indicates that the position cannot be selected. .

The correction item selection switch 406 is a switch for selecting image correction items of luminance, color signal R, color signal B, and contrast in the manual mode, and the correction item selection switch 406 is corrected each time the switch 406 is pressed as shown in FIG. Items can be switched cyclically. When the correction item selection switch 406 is pressed, the automatic mode is automatically switched to the manual mode. Note that the image correction items are not limited to the above embodiment,
R, G, B color correction, density correction, color γ correction, brightness γ
Correction, contrast correction, contour correction, etc. may be performed.

The correction value input switch 407 is a switch for inputting the correction amount of the image correction item selected by the correction item selection switch 406, and has a "+" switch and a "-" switch. "+" Switch or "-"
Each time the switch is operated, the correction amount of the selected image correction item is increased or decreased. The film feeding unit 402 includes a film feeding switch 409 for performing operations such as winding and rewinding the film 102.

The operation of one embodiment will be described with reference to the flow charts shown in FIGS. Power switch 403
Is started, the operation starts from step 501, and in step 502, it is confirmed whether or not the camera unit 401 is attached to the film feeding unit 402 by a camera switch (not shown). When the camera switch is in the ON state and both units 401 and 402 are separated, the process proceeds to step 518, and the position is set to the camera. On the other hand, when the camera switch is OFF and the camera unit 401 is attached to the film feeding unit 402, the process proceeds to step 503. It should be noted that whether or not the camera unit 401 is attached to the film feeding unit 402 may be determined depending on whether or not communication between both units is possible.

First, the case where the camera unit 401 is mounted on the film feeding unit 402 and the image of the film 102 is displayed will be described. In step 503, the camera / negative / positive position is set to a negative that is considered to be frequently used. Continued Step 504
Then, whether or not the cartridge 101 is loaded in the cartridge chamber 410 is confirmed by a cartridge loading detection switch (not shown). When the cartridge 101 is loaded, the process proceeds to step 505, and it is confirmed by the switch 106 whether or not the loaded cartridge 101 has been developed. If the loaded cartridge 101 has not been developed, the cartridge 101 is rejected by a mechanism (not shown) in step 519, and the process ends. In this reject operation, for example, the lid of the cartridge chamber 410 is opened and the cartridge 101 is ejected.

If the loaded cartridge 101 has been developed, the cartridge ID is read by a reading device (not shown) in step 506. This cartridge I
D is an ID unique to the cartridge, and the cartridge 10
It is recorded with a barcode and a symbol on the surface of 1. In step 507, it is confirmed whether the data disk information corresponding to the ID of the cartridge 101 is stored in the memory 124.

Here, the data disk is a disk that rotates in synchronization with the cartridge spool, and radial bar codes are recorded on the disk. In this specification, the bar code information on the data disc is referred to as data disc information. Data disc information includes film type (color / monochrome and negative / positive), number of shots, IS
0 sensitivity is included.

If the image of the film cartridge 101 has been displayed before and the data disc information of the film is stored in the memory 124, it is not necessary to read the data disc information again, and therefore, in step 515. The position stored in the memory 124 is set as the position, and the process proceeds to step 516. On the other hand, if the data disc information of this film is not stored in the memory 124, in step 508, the data disc information is read by a reading device (not shown). In step 509, it is confirmed whether the film 102 is a positive film based on the read data disc information. If the film 102 is a positive film, the process proceeds to step 513,
Set the position to "Positive". If it is not a positive film, check in step 510 whether it is a negative film,
If it is a negative film, the position is set to "negative" in step 512.

If positive or negative cannot be detected, a warning is given in step 511, and a step 512 is issued.
Proceed to and set the negative position, which seems to be frequently used for the time being. The cause of the non-detection of the positive / negative may be that the negative / positive information is not recorded in the cartridge 101 from the beginning or the failure of the reading device of the data disc information. In step 514, the ID of the loaded cartridge 101 and its data disk information are stored in the memory 124 in association with each other.
In a succeeding step 516, it is confirmed whether or not the magnetic recording information of the film 102 is stored in the memory 124. If the image of the film 102 has been displayed before and the magnetic recording information is stored in the memory 124, there is no need to read the magnetic recording information again, so the process proceeds to step 517, and the image of the film 102 is further read. It is confirmed whether the correction information is stored in the memory 124.

Here, the magnetic recording information is recorded in the leader portion of the film 102 and a predetermined magnetic recording portion of each photographing frame. The former includes information about the entire film 102 such as a title, and the latter includes information about each shooting frame such as shooting date, exposure value, print size, and information without image correction. The information without image correction is information for prohibiting image correction in the lab at the time of printing,
The film for which the gray chart is taken is printed only with the correction value for printing in gray. In the film image display device, only the minimum necessary correction is performed on the frame on which the information is recorded without image correction. This image correction will be described later.

In the case where the magnetic recording information of the loaded cartridge 101 is not stored in the memory 124, FIG.
The magnetic recording information of the film 102 is reproduced and the part of the film 102 where the image is not recorded, that is, the film base is imaged to detect the white balance value. In step 601 of FIG. 6, the motor control circuit 118 and the motors 104 and 105 are
The feeding of the film 102 is started by the following step 6
02, magnetic read circuit 120 and magnetic head 107
The magnetically recorded information on the film 102 is reproduced by. Then, the magnetic recording information reproduced in step 603 is stored in the memory 124 in association with the cartridge ID and the frame number. At step 604, it is confirmed whether or not the reading of the magnetic recording information of all the frames is completed. If not completed, the process returns to step 602, and if completed, the process proceeds to step 605.

Here, the white balance control for the positive film and the negative film will be described. Normally, when displaying an image on a monitor television, if the automatic white balance control is performed, the influence of the color of the film base and the illumination light source is corrected and the image is displayed in an appropriate color. But,
If the automatic white balance control is performed when an image of a special scene, for example, an image of a landscape dyed at sunset is broadcast, the correction is too effective and an image of a landscape of the daytime is displayed. Therefore, the automatic white balance control is stopped and the image is displayed, but in that case, the effect of the color of the film base and the illumination light source is not corrected, so it was necessary to perform the color correction manually and display the image. . Color correction by such a manual operation is troublesome, and it is difficult to completely correct it. In order to solve such a problem, in this embodiment, a white balance control with a fixed value is performed to automatically correct only the influence of the color of the film base and the illumination light source.

As described with reference to FIG. 1, the image area 1
The film 102 at 26 is illuminated by the illumination light source 111 through the diffusion plate 112, and the light transmitted through the film 102 is input to the CCD 114. Since the base color of the negative film varies depending on the type of film such as IS0 sensitivity and manufacturer, it is necessary to correct the color temperature shift due to the color of the film base. Therefore, for a negative film, the light transmitted through the film base is received by the CCD 114 prior to image display, the color temperature of the transmitted light is detected, and the color temperature shift due to the color of the film base, that is, the image of the film base is displayed. Detects the white balance value that makes white. When the automatic white balance control is not performed, the white balance control is performed with a fixed value calculated based on the transmitted light of the film base.

On the other hand, since the base of the positive film is transparent, the illumination light that has passed through the diffusion plate 112 remains as it is in the CCD.
It is incident on 114. Therefore, it is not necessary to detect the white balance value of the positive film each time before displaying an image, and the illumination light that has passed through the diffusion plate 112 in advance is received by the CCD 114 and the color temperature of the illumination light is detected to illuminate the film. A color temperature shift due to light, that is, a white balance value that makes an image of illumination light white is detected. When the automatic white balance control is not performed, the white balance control is performed based on the fixed value calculated based on the illumination light.

In step 605, it is confirmed from the previously read data disc information whether the film is a positive film. If it is a positive film, the white balance value has already been calculated based on the illumination light. If so, the process proceeds to step 606 to detect the white balance value based on the light transmitted through the film base. If negative film, step 60
At 6,607, one frame is wound further than the last frame, and the unexposed portion, that is, the film base is set in the image area 126. In step 608, the CCD 114 captures an image of the film base, and in step 609, the white balance value is detected based on the transmitted light of the film base. Then, the detected white balance value is stored in the memory 124 in step 610. When the white balance value is detected, the film 102 is rewound in steps 611 to 613, and the first frame is set in the image area 126.

Next, referring to FIG. 7, the magnetic recording information corresponding to the loaded cartridge 101 is stored in the memory 124, but the processing when the image correction information including the white balance value described above is not stored is described. explain. In this case, the reproducing operation of the magnetic recording information is unnecessary,
Only the white balance value is detected. In step 701 of FIG. 7, the feeding of the film 102 is started, and in the following step 702, it is confirmed from the data disc information whether the film is a positive film. In the case of positive film, the white balance value has already been detected based on the illumination light, so
It is not necessary to perform the detection operation again, and the process proceeds to step 711. On the other hand, in the case of a negative film, step 703
At 706, the film 102 is stopped at the time when the film is fed for a predetermined time (0.2 seconds in this embodiment) after the front end of the film 102 is detected by the interrupter 109,
The unexposed portion between the leading edge of the film 102 and the first frame, that is, the film base is set as the image area 12.
Set to 6. In steps 707 to 709, the film base is imaged by the CCD 114 as described above, and the white balance value is detected based on the transmitted light of the film base. Then, the detected white balance value is stored in the memory 124. When the white balance value is detected, the film 102 is fed in steps 710 to 712, and the first frame is set in the image area 126.

Next, the processing in the case where the magnetic recording information and the image correction information corresponding to the loaded cartridge 101 are stored in the memory 124 will be described with reference to FIG. In this case, neither reproduction of the magnetic recording information nor detection of the white balance value is necessary. Therefore, in steps 801 to 803, the first frame of the film 102 is set in the image area 126, and in step 804, the image of the first frame is stored in the memory 124. Confirm whether to correct using the stored value of. This confirmation is performed by the stored value cancel switch provided in the key group 123. When the correction is performed by the stored value, the process proceeds to step 805, and when the correction is not performed by the stored value, the process proceeds to step 901 of FIG. In step 805, the position and mode are set to the stored values in the memory 124, and the process proceeds to step 1001 in FIG.

If the correction is not performed based on the value stored in the memory 124 when displaying the image, step 901 in FIG.
Check whether it is a positive film or a negative film by referring to the data disc information. As shown in FIG. 16, in the case of a positive film, it is set to positive / auto 2 in step 905, and when there is information without image correction in a negative film, the process proceeds from step 902 to 904 and is set to negative / auto 2. If the image is not corrected on the negative film and there is no information, the process proceeds from step 902 to 903 to set negative / auto 1.
After setting the position and mode, go to Step 1 in Figure 10.
Proceed to 001.

Since a photographer using a positive film selects a filter or the like for photographing, he wants to display an image as it is on the film. If the automatic white balance control is performed when displaying an image, the effect of the filter used at the time of shooting is erased. Therefore, the auto 2 mode is set for the positive film, the auto white balance control is prohibited, and the white balance control is performed with a fixed value that only removes the influence of the illumination light. on the other hand,
Auto even if there is information without image correction with negative film 2
Set the mode. Since the information is set without image correction to prohibit image correction during printing,
Even when the image of the frame is displayed on the monitor TV, the white balance control is not performed by the automatic white balance control, but the white balance control is performed by a fixed value that removes the influence of the color of the film base. If the image is not corrected on the negative film and there is no information, the auto 1 mode is set. In general, an image taken with a negative film is often subjected to automatic white balance control and viewed with an appropriate color. Therefore, if there is no information without image correction, the automatic white balance control in the auto 1 mode is selected.

As described above, the image correction values such as the position, mode and color correction for the first frame have been set.
Proceed to and perform the image display operation. Step 10 of FIG.
In 01, the print aspect ratio is determined from the magnetic recording information of the frame set in the image area 126,
In the following step 1002, a mask corresponding to the aspect ratio is set. In step 1003, the image of the frame set in the image area 126 is captured by the CCD 114, the image is corrected by the image pickup circuit 115 according to the correction amount for each image correction item, and further included in the magnetic recording information by the video control circuit 116. The shooting date and time are superimposed on the image and displayed on the monitor television connected to the video output 125.

When the position selection switch 404 is operated in step 1004, the processing shown in FIG. 13 is executed. In step 1301 of FIG. 13, the selected position is detected. If the position is changed, the figure 1
9 or the mode corresponding to the new position is set according to FIG. In step 1302, an image correction value suitable for the set position and mode is set.

When the mode selection switch 405 is operated in step 1005, the processing shown in FIG. 14 is executed. In step 1401 of FIG. 14, the selected mode is detected. In step 1402, it is confirmed whether or not the manual mode is selected. When the manual mode is selected, the process proceeds to step 1403, and the image correction value at the manual time stored in the memory 124 is read. This image correction value is the correction item selection switch 4 in the manual mode.
06 and the correction value input by the correction value input switch 407. In step 1404, an image correction value suitable for the set position and mode is set. The image correction value includes the value stored in the memory 124 in the manual mode.

When the correction item selection switch 406 is operated in step 1006, the process proceeds to step 1008, and the position is forcibly set to the manual mode.
The process shown in 5 is executed. Step 1501 in FIG.
Then, the correction item selected by the correction item selection switch 406 is detected. In the following step 1502, the correction amount according to the operation of the correction value input switch 407 is calculated. In step 1503, the correction item and the correction amount are stored in the memory 124.

In this way, step 1501 of FIG.
Since the image correction item and the correction amount in the manual mode set in 1502 are stored in the memory 124 in step 1503, if the manual mode is selected in step 1402 of FIG.
The image correction item and the correction amount in the manual mode are read from 24, and the image correction value including the image correction item and the correction amount is set in step 1404. Therefore, if you set the image correction value of a frame in manual mode, even if you display the image in auto mode after that, the image of that frame will be displayed with the previously set image correction value when you return to manual mode. There is no need to start over.

Returning to FIG. 10 again, the description will be continued. When the rewinding operation of the film 102 is performed by the switch 409 in step 1007, step 101
6, the image correction values such as position, mode and color correction of the frame set in the image area 126 are stored in the memory 124 in association with the cartridge ID and frame number. Film 102 in steps 1017 and 1018

When the film feeding operation is performed by the switch 409 in step 1009, the process proceeds to step 1010, and it is confirmed whether or not the frame set in the image area 126 is the last frame. If it is the last piece, step 1011
To warn. If it is not the last frame, the process proceeds to step 1012, and the image correction values such as the position, mode and color correction of the frame set in the image area 126 are stored in the memory 124 in association with the cartridge ID and the frame number. In steps 1013 to 1015, the film 102 is fed and the next frame is set in the image area 126. As described above, since the final image correction value of the frame currently set in the image area 126 is stored in the memory 124 in association with the cartridge ID and the frame number, the frame is moved to the next frame. The image correction value of can be reliably stored.

When the next frame is set in the image area 126, the processing shown in FIG. 11 is performed. First, step 11
In 01, it is confirmed whether or not the image correction value of this frame is stored in the memory 124. If it is stored, step 11
It proceeds to 05 and confirms whether the stored value of the memory 124 is used for image correction of this frame. If the value stored in the memory 124 is used, the position in step 1106,
The stored value is set as the image correction value such as the mode and the color correction, and the process returns to step 1001 in FIG. 10 to display the image as described above. On the other hand, when the image correction information of the new frame set in the image area 126 is not stored, or when the image correction based on the stored value is not performed, step 1
At 102, it is confirmed from the magnetic recording information of this frame whether or not this frame was photographed in series with the previous frame. Further, in step 1103, it is confirmed from the magnetic recording information of this frame whether or not this frame was photographed in the continuous mode with the previous frame.
If the frame set in the image area 126 is a frame taken in the series or continuous shooting mode with the previous frame,
In step 1104, the same position, mode, and image correction value as the previous frame are set, and the process returns to step 1001 in FIG. 10 to display an image. If the image correction value of the current frame is not stored and it is not a frame photographed in the series or continuous shooting mode with the previous frame, FIG.
Returning to step 901, the position and mode are set again. In this way, the image is corrected with the same image correction value as the previous frame for the previous frame and the series, or for the frame shot in continuous shooting mode. It is not necessary to perform the image correction operation each time, and it is possible to enjoy the same color condition.
