In this case, an image for one frame is displayed on the monitor TV, and it is performed while watching the image.

[0007]

The conventional film image input devices described above use a two-dimensional image sensor as an image sensor. Therefore, the brightness and white balance of each frame, which are different depending on the shooting conditions, can be determined. Although there is an advantage that corrected image data can be obtained in real time, there is a problem that a two-dimensional image sensor is more expensive than a one-dimensional image sensor (line sensor).

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 magnetic recording / reproducing device 182 includes a magnetic head 18

The magnetic data recorded in the magnetic recording layer 114B of No. 4 is read, the magnetic data is processed and output to the CPU 160 to be recorded in the RAM 160A, and the data recorded in the RAM 160A of the CPU 160 is read and magnetically recorded. Magnetic head 182 after converting into a signal suitable for
It is output to A and recorded on the magnetic recording layer 114B of the film 114.

Next, the film image input device 1 having the above structure
The operation of 00 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 CPU
160 controls the film driving mechanism 170 to execute film loading (step 200). That is, the film 114 is sent out from the film cartridge 110, and the leading end of the film is wound around the winding shaft of the film winding section.

When the film loading is completed, the first pre-scan of the film 114 is executed. That is, as shown in FIG. 5, the film 114 is fed at a high speed of 148.0 mm / sec in the forward direction (see FIG. 4), and subsequently 148.0.
Rewind in the opposite direction at a high speed of mm / sec. First in the forward direction
During the pre-scan, the image data is captured via the CCD line sensor 142, and the optical data and the magnetic data are read via the optical data reading device 180 and the magnetic recording / reproducing device 182.

Next, the processing based on the image data captured during the first prescan will be described.

The CPU 160 inputs dot-sequential R, G, B signals from the A / D converter 150 shown in FIG. C
The PU 160 takes in 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 these offsets for each color signal. The offset data indicating the amount and the AWB data indicating the gain adjustment amount are stored in the random access memory (RAM) 160A built in the CPU for each frame. 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. Incidentally, C
The PU 160 can detect each frame of the film 114 based on the optical data and / or the magnetic data added via the optical data reading device 180 and the magnetic recording / reproducing device 182, and by counting each frame. The frame number can also be detected.

Next, the second prescan of the film 114 is executed. That is, as shown in FIG.
Is re-fed in the forward direction at a high speed of 74.0 mm / sec, and then rewound in the reverse direction at a high speed of 148.0 mm / sec. At the time of the second prescan in the forward direction, the image data is captured again via the CCD line sensor 142. When capturing this image data, the CPU 160 causes the RAM 1
Aperture control device 1 based on AE data stored in 60A
The diaphragm 134 is controlled for each frame via 64. Incidentally, C
When the CD line sensor 142 having an electronic shutter mechanism is used, the exposure amount can be adjusted by controlling the charge storage time in the CCD line sensor 142 via the CCD drive circuit 144.
In this case, the diaphragm 134 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 AW data, AWB data, etc., 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 and the chroma signal C _{r / b} output from the second signal processing circuit 152 are stored in the memory control circuit 15.
The data is sequentially stored in the CCD buffer M1 via the memory 4. still,
As described above, since the film 114 is fed at a speed 8 times the feeding speed when the standard film image is captured,
As shown in FIG. 7A, the number of pixels in the same direction as the film feeding direction of one frame 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 is set to 5 as shown in FIG.
It has a storage capacity for storing data of 12 × 1024 pixels, and thus can store image data of 5 × 4 × 2 (= 40) frames. That is, the CCD buffer M1 stores image data indicating index images for 40 frames.

The display buffer M2 has a storage capacity for storing data of 512.times.1024 pixels as shown in FIG. 7B, but 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-mentioned storage operation in the CCD buffer M1, the contents stored in the CCD buffer M1 are stored in the display buffer M2.
When a film cartridge that has been transferred to the normal wind type camera (normal camera) is set as a result, as shown in FIG. 8A, the monitor TV 109 sequentially displays frame images from the upper left. Will be displayed.

Since the display buffer M2 can store only 20 frames of image data at a time, the CCD buffer M1
When the image data of the 21st frame is input to, 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.

On the other hand, when the film cartridge photographed by the prewind type camera is set and the total number of frames is 40, for example, as shown in FIG. 8B, frame numbers 40, 39, The frame images superposed by ... Are sequentially displayed from the lower right of the screen of the monitor TV 109. This makes it possible to match the shooting order of each frame with the frame number.

In the case where the shooting order of each frame and the frame number are always displayed in the same manner as described above, at least the film photographed by the prewind type camera is provided with optical or magnetic data indicating the prewind. Need to be recorded.

When the index image is created as described above and the index image is displayed on the monitor TV 109, one frame is interactively displayed on the monitor TV 109 using the keypad 120 while watching the index image. The necessary editing and other specifications are performed (step 204).

That is, as shown in FIG. 1, the keypad 120 includes the up, down, left and right keys 121 to 124 and the "UP" key 1.
25, "DOWN" key 126, "Execute" key 12
7 and 8 keys of the "Cancel" key 128.

Now, as shown in FIG. 9, the CPU 160 causes the monitor TV 109 to display the characters indicating various setting menus together with the index images for 20 frames. still,
“PSET” indicates the setting of the number of prints and “ROT
“S” indicates the vertical and horizontal setting of the frame, “SKPS” indicates the setting of the non-displayed frame at the time of reproduction, “VIEW” indicates that each frame is reproduced, and “PLAY” indicates each frame at a constant interval. Indicates continuous playback and "E
“NV” indicates environment settings such as interval time and background color, and “END” indicates the end of editing using the index image.

The above menu is selected by the keypad 120.
By using the "UP" and "DOWN" keys 125 and 126 to move the cursor (which distinguishes it from other menus by changing its color) and press the "Execute" key 127. . 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. 9, when the cursor is moved to "SKPS" and the "Execute" key 127 is pressed, the skip setting menu is displayed.

In this skip setting menu, for example, when the frame number 1 is set as a non-displayed frame, the frame number 1 is selected as the frame to be edited,
Press the “UP” key 125. As a result, the character "SKIP" is displayed in the frame of frame number 1. And
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-displayed frame is stored in the RAM 160A of the CPU 160. Incidentally, CC
Since the image data remains as it is on the D buffer M1, the "DOWN" key 126 is pressed to display the characters "VIEW" in the frame with the frame number 1.
When the "Execute" key 127 is pressed, the image data corresponding to the frame number 1 is transferred from the CCD buffer M1 to the storage area corresponding to the frame number 1 in the display buffer M2, whereby the frame display is performed and the RAM 160A is displayed. The stored data indicating the frame number 1 of the non-displayed frame is cleared. In this way, display / non-display frames are set. The setting contents can be canceled by pressing the "Cancel" key 128.

Next, the case of switching the vertical and horizontal directions of frames will be described.

In this case, as shown in FIG.

When the "UP" key 125 is pressed from this state, the direction of the arrow rotates clockwise by 90 degrees for each one-push, and when the "DOWN" key 126 is pressed, the direction of the arrow is 90 for each one-push. Rotate counterclockwise each time. When the "Execute" key 127 is pressed after selecting the vertical direction by the arrow in this way, the image data in the storage area of the target frame of the display buffer M2 is rotated in accordance with the selected vertical direction. Note that, as shown in FIG. 7, 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 for each frame will be described.

In this case, as shown in FIG.
Move the cursor to "ET" and press the "Execute" key 127 to display the print count 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. 11, 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. After selecting the number of prints in this way, click "Execu
When the "te" key 127 is pressed, the displayed number of prints is set and stored in the RAM 160A of the CPU 160.

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.

Furthermore, a frame switching method for switching the display from a certain frame to the next frame can be designated. For example, when switching the display from one frame to the next, in addition to the frame switching method that instantly switches the display screen,
It is possible to specify the frame switching method for switching by scrolling the screen, the frame switching method for switching between fade-out / fade-in, etc. 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.

When the editing with the index image is completed, it is subsequently selected in step 206 (FIG. 4) whether or not to edit each frame. This selection is also a monitor TV
This can be done by operating the keypad 120 while looking at the screen of 109.

Next, the case of editing each frame will be described.

In this case, first, the display frame number is set to 1 (step 208), and as shown in FIG. 5, the film 114 is fed forward at a rate of 9.25 mm / sec for one frame. The frame with the frame number 1 is scanned (main scan) (step 210). During this main scan, the image data is taken into the CCD buffer M1 via the CCD line sensor 142.

When fetching this image data, 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 stored 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 playback menu setting mode, the frame number is displayed on the monitor TV 109 as shown in FIG.
Is displayed on the upper left side 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"

"ROT" indicates vertical and horizontal setting of frames, "SET" indicates setting of the number of prints, "IDX" indicates display of the index image described above, and "ENV" indicates environmental settings such as interval time and background color. "END" indicates the end of editing using an image of one frame.

To select the above menu, use the "UP" and "DOWN" keys 125 and 126 of the keypad 120 to move the cursor to the position of the menu to be executed as in the case of editing using the index image described above. , "E
This is done by pressing the "xecute" key 127.

When the cursor is moved to "ZOOM" and the "Execute" key 127 is pressed, the zoom setting menu is displayed (step 212). In this zoom setting menu, the up, down, left and right keys 121 to 1 of the keypad 120
By operating 24, the pointer is appropriately moved to indicate the zoom center. Then, by pressing the "UP" key 125 or the "DOWN" key 126, zoom-up or zoom-out by electronic zoom is performed. After performing the desired zooming in this way, pressing the "Execute" key 127 confirms the zoom setting, and the CPU 160
It is stored in the RAM 160A (step 214).
In the case of printing with a video printer (not shown) connected to the film image input device 100, printing is performed according to a print instruction from the printer side (step 21).
6).

In the electronic zoom, for example, 0.5
Zooming in the range of up to 1.5 times is possible. Then, the magnification by the electronic zoom becomes 1.5, and "U
When zoom-in is instructed by the "P" key 125, low-speed main scan is performed. In this case, the film 114 is set to 4.63 mm / sec (1/2 of the normal main scan speed).
And feed it in the forward direction with the CCD line sensor 14
The CCD output of 2 is taken in with reference to the designated zoom center without thinning out. As a result, the image data zoomed in twice as much as in the normal main scan is captured. By electronically zooming this image data, it becomes possible to zoom up to 3 times.

Furthermore, while using the keypad 120, a title to be displayed superimposed on the frame image can be input (steps 218 and 220), the character data indicating the title is stored in the RAM 160A of the CPU 160, and " By moving the cursor to "MASK" and pressing the "Execute" key 127, a framed setting menu can be displayed, and the size and position of the frame provided around the display frame can be input using the keypad 120. (Steps 224, 226). After confirming these inputs, printing can be performed by the video printer as in step 216 (steps 222 and 228).

Next, the case of setting the number of prints of display frames and the like will be described.

In this case, the cursor is moved to "SET" and the "Execute" key 127 is pressed to display the print number setting menu (steps 230, 232).

That is, when the print number setting menu is selected, "SET" is displayed at the upper left of the image of the frame as shown in FIG. 13, and the three target items "P" are displayed.
RINT 0 ”,“ DATE ON ”,“ PLAY V ”
“EW” is displayed. These target items are selected by operating the up / down keys 121 and 122, and the selected target items are blink-displayed. "PRINT

When the "Execute" key 127 is pressed, the displayed number of prints and the like are set, and the RAM 160A of the CPU 160 is set.
Stored in. If the number of prints set in the index image is different from the number of prints set in the single frame setting menu, the number of prints set in the single frame setting menu is prioritized.

Next, the case of setting the interval time of the display frame will be described.

In this case, move the cursor to "ENV" and press the "Execute" key 127 to display the environment setting menu.

When the environment setting menu is selected, the image is muted, and "INTERVA" is displayed as shown in FIG.
L TIME: 10 "," BACK COLOR: BL
Only the characters "ACK" are displayed. These target items are selected by operating the up / down keys 121 and 122, and the selected target items are blink-displayed.
If you select "INTERVAL TIME: 10",
The "UP" key 125 and the "DOWN" key 126 can be used to specify the display time when displaying one frame at a time. When "BACK COLOR: BLACK" is selected, the "UP" key 125 and "DOWN" are selected. Key 12
6, the background color of the display frame can be designated from eight colors. When the "Execute" key 127 is pressed after designating the interval time and the like in this way, the displayed interval time and the like is set and stored in the RAM 160A of the CPU 160.

After the display frame is edited as described above, when the cursor is moved to "END" and the "Execute" key 127 is pressed, the display frame is edited (step 2).
34) On the other hand, when the cursor is moved to "FWD" or "REV" and the "Execute" key 127 is pressed, the frame number is increased or decreased by 1 (step 236), and step 2
Return to 10. As a result, another display frame can be edited in the same manner as described above.

When the editing of the display frame is completed (step 234), the film 114 is moved to the 14th position as shown in FIG.
It is fed at a high speed of 8.0 mm / sec in the forward direction, and during this feeding, magnetic data read in advance from the magnetic recording layer 114B of the film 114 and stored in the RAM 160A of the CPU 160, the editing using the index image is performed. Data indicating the contents, data indicating the contents of editing using the display frame, and the like are recorded again on the magnetic recording layer 114B of the film 114 (step 238). Then, the film cartridge 110 is unwound in the reverse direction at a high speed of 148.0 mm / sec, and the film cartridge 110 is taken out (step 240).

On the other hand, if it is determined in step 206 that the editing using the display frame is not to be executed, step 244,
In step 244, writing of the film 114 to the magnetic recording layer 114B and removal of the film cartridge 110 are performed as in steps 238 and 240.

Although not shown in the flow chart of FIG. 4, each frame of the film is reproduced one by one or continuously on the monitor TV 109 at a predetermined interval according to the editing contents edited as described above. You can enjoy the images. Further, when the film cartridge 110 which has been edited once is loaded, it can be reproduced on the monitor TV 109 according to the edited contents. However, in this case, it is necessary to read magnetic data, AE data, AWB data and the like from the film before reproducing at least one frame. Furthermore, if the film transport sequence during one-frame playback is changed in accordance with the film shot by the normal wind type camera or the film shot by the prewind type camera, the films can always be played back in the shooting order.

By the way, in the case of a film capable of recording magnetic data and optical data, it is conceivable that both magnetic data and optical data are recorded for the same type of processing. Although the optical data optically recorded at the time of shooting cannot be rewritten, the magnetic data can be rewritten at the time of editing, and as a result, the contents of the optical data and the contents of the magnetic data may differ. For example, it is conceivable that data indicating a high-definition format is optically recorded by a camera at the time of shooting, and then data indicating a panoramic format is written on a magnetic recording layer of a film at the time of editing.

Therefore, the CPU 160 inputs the optical data and the magnetic data read by the optical data reading device 180 and the magnetic recording / reproducing device 182, respectively, and compares the data recorded on the same frame of the film with each other. Then, when it is detected based on the comparison result that data showing different contents is recorded for the same type of process, the process based on the contents of the magnetic data is executed. If only the optical data is recorded, or if an error occurs in the magnetic data, processing is performed based on the optical data. Further, when an error is found in the magnetic data, the magnetic data can be corrected based on the optical data.

Further, in this embodiment, the photographing conditions such as the brightness and the white balance at the time of photographing are detected for each frame, but the present invention is not limited to this, and based on the magnetic data read from the magnetic recording layer of the film. When it is detected that there are a plurality of frames having substantially the same shooting date and time, the shooting conditions of these frames may be made to match the shooting conditions detected for the first frame. Note that the shooting dates and times are substantially the same when the shooting dates are the same and the shooting times of the respective frames are close to each other so that it can be determined that the shooting is performed under the same scene or the same shooting condition.

Further, in this embodiment, as shown in FIG. 5, the magnetic data is read / read only when the film is fed in the forward direction.
I am trying to write and read image data,
Not limited to this, when the film is fed in the reverse direction as shown in FIG. 6, the image data of the index image may be read, the magnetic data may be written, and the like. It is possible to shorten the time until the film is taken out after the frame editing is completed. In this case, the feeding direction of the film is reversed at the time of reading the magnetic data and at the time of writing, so that it is necessary to reverse the sending order of the magnetic data at the time of writing.

Furthermore, in the present embodiment, the processing of the image data of the index image of the film taken by the prewind type camera is shown in FIG. 8B, but the present invention is not limited to this, and the film transport sequence is not limited to this. Alternatively, for example, the image data or the like may be read at the time of rewinding (when the film is fed in the reverse direction) shown in FIG.

Next, a method for automatically discriminating the top-bottom direction of the frames recorded on the film will be described.

As described above, during prescan, CP
U160 is a dot-sequential R, from the A / D converter 150.
G and B signals are input, and these signals are processed to detect the AE data and the like of each frame. Based on the R, G, and B signals, one frame is divided into nine areas as shown in FIG. divided into detects data E ₁₁ to E ₃₃ indicating the brightness of each region, to automatically determine a vertical direction of each frame by performing the processing shown in FIG. 16.

That is, as shown in FIG. 16, the above-mentioned data of each frame is
Data E₁₁~ E₃₃(Step 300), FIG.
Data X indicating the brightness of the four sides as shown in_1,X_3,Y
_1,Y ₃Is calculated by the following equation (step 302).

X ₁ = E ₁₁ + E ₁₂ + E ₁₃ X ₃ = E ₃₁ + E ₃₂ + E ₃₃ Y ₁ = E ₁₁ + E ₂₁ + E ₃₁ Y ₃ = E ₁₃ + E ₂₃ + E _{33 Then} , in steps 304 to 316,
The four data X _1, X _3, Y _1, Y ₃ are compared with each other to determine which of the four surrounding sides is brightest. Then, it is determined that the brightest side is close to the sky and the illumination, and it is determined that the image is upright in the direction of the side. That is, as shown in FIG. 5, an arrow A indicating the vertical direction,
When the side corresponding to the data Y ₁ is the brightest among B, C, and D, it is determined that the image is upright in the direction of the arrow A, and similarly, the side corresponding to the data Y ₃ is the brightest. In this case, it is determined that the image is upright in the direction of arrow B, and when the side corresponding to the data X ₁ is the brightest, it is determined that the image is upright in the direction of arrow C, and the data X ₁ is upright. _When the side corresponding to ₃ is the brightest, it is determined that the image is upright in the direction of arrow D.

In this way, the vertical direction of each frame can be automatically determined from the image data of each frame obtained during the prescan. The CPU 160 can store the data indicating the vertical direction thus determined in the RAM 160A and rotate each frame of the index image according to the vertical direction of each frame.

Since the top-bottom direction of each frame which is automatically discriminated as described above is not always correct, for the top whose top-bottom direction is erroneously discriminated, use the keypad 120 as described above. It can be modified. Also, 1
In the film of two film cartridges,
It is difficult to think of a case in which a frame in which the image is upright in the direction of arrow A and a frame in which the image is upright in the direction of arrow B coexist as shown in FIG. You may make it unified to one.

[0104]

As described above, according to the film image input method and apparatus of the present invention, the cost can be reduced by using the line sensor as the image sensor, and the entire film can be obtained. The image data of the frame can be quickly taken in, whereby the index image can be created in a short time, and the editing work for a series of images can be easily performed while viewing the index image. Since the index image is not an image for viewing, the image quality is not a problem, and it is possible to sufficiently create even rough image data that has been captured quickly.
