Here, in the case where the image of 6 frames displayed on the display unit 7 is displayed upside down, the user
The key “V” + “Y” (not shown) on the keyboard 6 is pressed. As a result, the system control unit 5 controls so that the image data of all the frames stored in the main memory 21, that is, the image data of one film is converted into the image data rotated by 180 °. Then, the system control unit 5 controls the memory control unit 2 so that the image data rotated by 180 ° is supplied to the display unit 7 via the video memory 22. As a result, the image of 6 frames is displayed upside down on the display unit 7 (step S13).

Next, when the images of the six frames displayed on the display unit 7 are misaligned, the key "V" + "album" (not shown) on the keyboard 6 is pressed. As a result, the system control unit 5 controls the memory control unit 2 so that the frame position adjustment screen data preset in the video memory 22 is supplied to the display unit 7. Therefore, the display unit 7 displays a frame position adjustment screen (not shown). Then, the user adjusts the position of the frame by operating each key of the keyboard 6 on the frame position adjustment screen. In accordance with this key operation, the system controller 5 causes the memory controller 2 to adjust the frame position.

As a result, the system control unit 5 controls the memory control unit 2 so that the PASS / Panorama / Wide size modes are released (step S15).

Next, when it is desired to display only one arbitrary frame, the user presses a key "V" + "F" (not shown) on the keyboard 6. As a result, the system control unit 5 controls the memory control unit 2 so that only one arbitrary frame of the six frame images currently displayed on the screen is displayed on the screen. Therefore, a one-frame screen as shown in FIG. 13 is displayed on the display unit 7 (step S16).

Next, when returning from the one-frame screen shown in FIG. 13 to the previous screen, the user presses the unillustrated key "V" + "F" of the keyboard 6. As a result, the system control unit 5 controls the memory control unit 2 so that the 6-frame screen data of the previous screen is supplied to the display unit 7. Therefore, the display unit 7 displays the previous screen shown in FIG.
The 6-frame screen shown in 2 is displayed.

Next, the system control unit 5 generates a histogram of each color component from the image data of each frame stored in the main memory 21, and calculates a proper correction amount based on this histogram (step S17).

Next, with respect to the 6-frame image currently displayed on the display unit 7, necessary step processes from the frame position adjusting process in step S14 to the density and color correcting process in step S17 are performed. It is judged whether or not it has been broken (step 18).

For the image of 6 frames, the above step S14
If the processes of to S17 are not completed, the processes from step S14 are repeated until they are completed.

With respect to the image of 6 frames, the above step S14
It is determined that each process of S17 to S17 is completed (step S1
In the case of 8), the user presses a key "EXEC / NEXT" (not shown) on the keyboard 6.

Next, it is determined whether or not each step processing from the 6-frame display processing in step S12 to the 6-frame end determination processing in step S18 has been performed on all the frame images recorded on the film. (Step S19).

If the processing of steps S12 to S18 has not been completed for all the frame images recorded on the film, the processing from step S12 is repeated until the processing is completed.

When the processes of steps S12 to S18 have been completed for the images of all frames recorded on the film, the user presses a key "EXEC / NEXT" (not shown) on the keyboard 6. As a result, the system control unit 5 controls the memory control unit 2 so that the main scan start screen data preset in the video memory 22 is supplied to the display unit 7. Therefore, the display unit 7

In the main scan start screen shown in FIG. 14, the main scan operation is started by pressing a key "SCAN" (not shown) of the keyboard 6. The prescan operation is stopped by pressing a key "V" + "SCAN" (not shown) on the keyboard 6.

Then, the user presses a key "SCAN" (not shown) on the keyboard 6. As a result, the system control unit 5 controls the memory control unit 2 so that the screen image during the main scan preset in the video memory 22 is supplied to the display unit 7. Therefore, the display unit 7
Displays a screen during main scan as shown in FIG. Then, the system control unit 5 performs various controls so that the main scan operation is performed.

That is, as shown in FIG. 6, the system control unit 5 causes the set film to be fed in the reverse direction during the main scan as opposed to the forward feeding of the film during the prescan. The control unit 1 is controlled. As a result, the scanner 11 sequentially reads the images of the respective frames recorded on the film in the reverse direction, and stores the read image data as digital image data in the main memory 21 (step S20).

Next, the above-mentioned signal processing unit uses the correction proper amount obtained during the pre-scan, and the main memory 21
A correction process is performed on the images of the respective frames stored in, and the corrected image data and frame number information on the film corresponding to the image data are supplied to the display unit 7 via the video memory 22. . Thereby, on the display unit 7,
While the image based on the corrected image data is displayed,
Frame number information corresponding to the image is displayed (step S21).

Further, the signal processing section supplies the corrected image data to the disk drive 42 via the disk interface section 41. As a result, the disc drive 42, under the control of the disc control unit 4,
The corrected image data from the signal processing unit is recorded on the set disc (step S22).

Next, the system control section 5 determines whether or not the main scan processing in step 20 and the disk recording processing in step S21 have been performed on the images of all the frames recorded on the film. Judge (step S2

Next, the number of remaining frames and the number of remaining albums on the disc are calculated (step S24). Here, FIG. 16 is a flowchart showing an acquisition process of the number of remaining frames and the number of remaining albums on the disc. Below, FIG.
Will be explained.

First, the system control unit 5 issues a "remaining frame number / remaining album number information" request to the disc control unit 4 (step S241).

Next, the disc control unit 4 requests the "remaining frame number / remaining album number information" from the system control unit 5 to determine the number of remaining frames based on the recording resolution mode set in step S5. Calculate (step S2
42).

That is, when the standard mode is set,
As described above, only 200 HD resolution images can be recorded on one disc, and the data amount of one image is 10 clusters. In this case, the number of remaining frames is = (200 × 10− (the number of recorded HD images × 10 + the number of recorded UD images × 20)) / 10

When the high resolution mode is set,
As described above, only 100 images of UD resolution can be recorded on one disc, and the data amount of one image is 20 clusters. In this case, the number of remaining frames is = (100 × 20− (number of recorded HD images × 10 + number of recorded UD images × 20)) / 20

After calculating the number of remaining frames as described above,
The disc control unit 4 calculates the number of remaining albums (step S243). That is, as described above, since the maximum number of albums on one disc is 25, the number of remaining albums can be calculated by the formula: number of remaining albums = 25−number of recorded albums. The information on the number of recorded albums is acquired from the management file of the disc.
