The CCD line sensor 142 has a sensor for, for example, 1024 pixels in the direction orthogonal to the film feeding direction. Further, the number of pixels in the same direction as the film feeding direction of one frame changes according to the film feeding speed when the period of the read gate pulse of the CCD driving circuit 144 is not changed. The number of pixels at each speed of 1/2, 1, 8, and 16 times the feeding speed when the film image is captured is 1792 pixels, 896 pixels, 112 pixels, and 56 pixels.

In this way, the CCD line sensor 142

The film driving mechanism 170 engages with the spool 112 of the film cartridge 110 and drives the spool 112 in the forward / reverse direction, and the film winding mechanism for winding the film 1 delivered from the film supplying section. It is composed of a pick-up section and a means which is disposed in the film transport path and which holds the film 1 between a capstan and a pinch roller and sends the film 1 at a constant speed. The film supply unit drives the spool 112 of the film cartridge 110 in the clockwise direction in FIG. 4 to feed the film 1 from the film cartridge 110 until the leading end of the film is wound by the film winding unit. .

The magnetic recording / reproducing apparatus 182 includes a magnetic head 18
2A, and reads the magnetic information recorded in the magnetic recording layer 1B of the film 1 via the magnetic head 182A,
The magnetic information is processed and output to the CPU 160 to be RAM
160A, and the RAM 160 of the CPU 160
The data recorded in A is read, converted into a signal suitable for magnetic recording, and then output to the magnetic head 182A.
Recording is performed on the magnetic recording layer 1B of the film 1.

Next, the film player 100 having the above structure.
The operation of will be described with reference to the flowchart shown in FIG. First, when the film cartridge 110 is set on the film cartridge tray 102, the CP
U160 controls the film drive mechanism 170 to execute film loading (step 200). That is, the film 1 is sent out from the film cartridge 110,
Wrap the leading edge of the film around the winding shaft of the film winding section.

When the film loading is completed, the first prescan of the film 1 is executed. That is, as shown in FIG. 6, the film 1 is fed in the forward direction at a high speed of 148.0 mm / sec. At the time of this first pre-scan, CC
Image data is captured via the D line sensor 142, and magnetic information is read via the magnetic recording / reproducing device 182.

Next, the processing based on the image data captured during the first prescan will be described. CPU
160 receives the dot-sequential R, G, B signals from the A / D converter 150 shown in FIG. The CPU 160 fetches the R, G, and B signals of all frames separately, calculates the offset amount for each color signal and the gain adjustment amount for each color signal for adjusting the white balance, and the offset for each color signal. Offset data indicating the amount and AW indicating the gain adjustment amount
The B data is stored for each frame in the RAM 160A with a built-in CPU. Further, the AE data indicating the brightness of each frame is stored in the RAM 160A from the R, G, B signals of each frame. still,
The CPU 160 can detect each frame of the film 1 based on the magnetic information applied via the magnetic recording / reproducing device 182, and can also detect the frame number by counting each frame.

Next, the second pre-scan of the film 1 is executed. That is, as shown in FIG.
Rewind in the opposite direction at a high speed of 0 mm / sec. At the time of this second pre-scan, image data is captured again via the CCD line sensor 142. At the time of loading this image data, the CPU 160 stores the A stored in the RAM 160A.
The diaphragm 134 is controlled for each frame via the diaphragm controller 164 based on the E data. The CCD line sensor 1
When the one having an electronic shutter mechanism is used as 42, the exposure amount can be adjusted by controlling the charge accumulation time in the CCD line sensor 142 via the CCD drive circuit 144. In this case, Aperture 1
34 and the diaphragm control device 164 are unnecessary.

Further, the CPU 160 causes the first signal processing circuit 151 to adjust the offset amount and white balance of the R, G, B signals for each frame. That is, CPU1
60 outputs the offset data for each color signal of each frame stored in the RAM 160A to the first signal processing circuit 151,
The first signal processing circuit 151 adjusts the offset amount of the dot-sequential R, G, B signals based on this offset data. Similarly, the CPU 160 outputs the AWB data for each color signal of each frame stored in the RAM 160A to the first signal processing circuit 151, and the first signal processing circuit 151 outputs the AWB data.
The gains of the dot-sequential R, G, B signals are adjusted based on the data.

Since the image data of each frame is adjusted based on the AE / AWB data and the like, good image data can be taken in regardless of the shooting conditions of each frame. The image data of each frame thus adjusted, that is, the luminance signal Y output from the second signal processing circuit 152.
The chroma signal C _{r / b} is sequentially stored in the CCD buffer M1 via the memory control circuit 154.

As described above, since the film 1 is fed at a speed 8 times as fast as the feeding speed when the standard film image is captured, as shown in FIG. The number of pixels in the same direction as the direction is 112 pixels. Further, the CCD line sensor 142 has a sensor for 1024 pixels in the direction orthogonal to the film feeding direction as described above, but by thinning out to 1/16, it is orthogonal to the film feeding direction of one frame. The number of pixels in the direction is 64 pixels. Then, the CCD buffer M1 has a storage capacity for storing data of 512 × 1024 pixels as shown in FIG. 7A, whereby 5 × 4 × 2 (= 40).
Image data for frames can be stored. That is, C
Image data indicating an index image for 40 frames is stored in the CD buffer M1.

The display buffer M2 has a storage capacity for storing data of 512.times.1024 pixels as shown in FIG. 7B. However, when storing the image data indicating the index image, it is set to 1 The pixels of the frame are enlarged to 73 × 128 and the image data of 5 × 4 (= 20) frames are stored. When displaying the index image on the monitor TV 109, the upper left 480 of the display buffer M2 is displayed.
An area of × 640 pixels is read (FIG. 7 (B),
(See (C)).

Now, in the CCD buffer M1, FIG.
As shown in (A), when the image data of each frame is sequentially read from the upper left storage area toward the right in the reading order of the image data of each frame at the time of the above scanning, and four frames are stored, one line goes down. The data is sequentially stored from the storage area to the right again. When 5 lines (4 × 5 = 20 frames) have been stored, they are similarly stored in the adjacent 20-frame storage area.

Even during the above storage operation in the CCD buffer M1, the contents stored in the CCD buffer M1 are stored in the display buffer M2.
Transferred to. Since the display buffer M2 can store only 20 frames of image data at a time, the CCD buffer M2
When the image data of the 21st frame is input to 1, the rewriting and reading of the image data to the display buffer M2 are performed so that the index image is scrolled upward. For example, when the 21st frame of image data is input to the CCD buffer M1, the frame numbers 1 to 1 of the display buffer M2 are input.
The image data in the storage area for one row of 4 is cleared,
The image data of the frame is written and the scan start address at the time of outputting the video signal is changed to the second line.
As a result, the index image scrolled upward by one line is displayed on the monitor TV 109. When the image data of all the frames are stored in the CCD buffer M1 in this way, the scroll or screen is switched downward so that the index images of the frame numbers 1 to 20 are displayed again on the monitor TV 109.

By the way, the CPU 160 sets the frame number to each frame in the reading order of the image data of each frame at the time of scanning, and outputs the character signal indicating the frame number of each frame, As shown in FIG. 8, the index image in which the frame number is superimposed is displayed. When the index image is created as described above and the index image is displayed on the monitor TV 109, the keypad 120 is used while watching the index image, and the monitor TV is displayed.
Various information (hereinafter referred to as automatic reproduction information) necessary for reproducing a desired film image is input to 109 (step 204).

When the menu is selected, the first frame becomes the frame to be edited, and the frame number of the first frame is currently displayed (the frame number is blinked). The selection of the frame to be edited can be performed by operating the up, down, left, and right keys 121 to 124 of the keypad 120.

Now, as shown in FIG. 8, when the cursor is moved to "SKPS" and the "Execute" key 127 is pressed, the skip setting menu is displayed. In the skip setting menu, for example, when the frame number 1 is set as a non-display frame, the frame number 1 is selected as the frame to be edited and the "UP" key 125 is pressed. As a result, the character "SKIP" is displayed in the frame of frame number 1. When the "Execute" key 127 is pressed, the storage area corresponding to the frame number 1 of the display buffer M2 is filled with a clear color, and the data indicating the frame number 1 of the non-display frame is stored in the RAM 160A of the CPU 160. Since the image data remains as it is on the CCD buffer M1, the "DOWN" key 12
After pressing 6 to display the character "VIEW" in the frame with frame number 1, press the "Execute" key 127, and the memory area corresponding to frame number 1 in the display buffer M2 corresponds to frame number 1. The image data is transferred from the CCD buffer M1, and by this, the frame display is performed, and R

In this way, after selecting the vertical direction with the arrow, press the "Execute" key 127 and the display buffer M
The image data in the storage area of the target frame 2 is rotated according to the selected vertical direction. As shown in FIG. 8, since the number of pixels in the vertical and horizontal directions of one frame is different, the image is reduced when rotating from horizontal to vertical, and enlarged when rotating from vertical to horizontal.

Next, the case of setting the number of prints of each frame will be described. In this case, as shown in FIG. 10, move the cursor to "PSET" and press the "Execute" key 127 to display the print number setting menu. When the print number setting menu is selected, the frame number of the frame to be edited is blinked as shown in FIG. 10, and the number of prints is displayed in the image of the frame. As for the number of prints, 0 is displayed in advance in the image of the frame. When the "UP" key 125 is pressed from this state, the number is incremented by 1 for each push, and "DOWN" is displayed. When the key 126 is pressed, the number is decremented by 1 for each push. In this way, after selecting the number of prints, press the "Execute" key 127 to set the displayed number of prints.
It is stored in the RAM 160A of U160.

Further, print formats such as high-definition, panorama, normal, etc. corresponding to the aspect ratio of an image can be designated for each frame. In this case, if the aspect ratio of the frame of the index image is changed according to the format designation, which format is designated can be visually recognized on the index image. Further, a frame switching method when switching the display from one frame to the next frame can be specified. For example, when switching the display from one frame to the next frame, in addition to the frame switching method that switches the display screen instantly, you can specify the frame switching method that scrolls the screen to switch, the frame switching method that switches with fade-out / fade-in Can be done while looking at the index image.

After performing the editing while looking at the index image as described above, when the cursor is moved to "END" and the "Execute" key 127 is pressed, the editing using the index image ends.

In this case, first, the display frame number is set to 1 (step 208), and as shown in FIG. 6, the film 1 is fed at a rate of 9.25 mm / sec for one frame in the forward direction, and the frame number 1 is displayed. The frame is scanned (main scan) (step 210). During this main scan, the image data is transferred to the CCD buffer M1 via the CCD line sensor 142.
Is taken into.

When this image data is taken in, the CPU 1
60 is AE data and AWB stored in the RAM 160A
Since the image data of each frame is adjusted based on the data or the like, good image data can be captured regardless of the shooting conditions of each frame. Also, in this way CC
The number of pixels for one frame captured in the D buffer M1 is 512 × 896 pixels as shown in FIG. That is, the CCD output of the CCD line sensor 142 having a sensor for 1024 pixels is decimated to 1/2 during the main scan, so that the number of pixels in the direction orthogonal to the film feeding direction of one frame is 512, and the film is also The feeding speed is 1 / compared to when the image data of the index image is captured
By setting the number to 8, the number of pixels is 896, which is eight times the number of pixels (112 pixels) in the same direction as the film feeding direction of one frame of the index image.

The image data for one frame captured in the CCD buffer M1 as described above is displayed in the display buffer M2.
Image data of one frame is displayed on the monitor TV 109 by being repeatedly read and stored in the display buffer M2. In the single-frame reproduction menu setting mode, the frame number is displayed on the monitor TV 109 as shown in FIG.
Is displayed on the upper left of the screen, and characters indicating a setting menu or the like necessary for editing one frame are displayed on the right side of the screen of the monitor TV 109. "FWD" indicates the next frame playback, and "RE"
