[Conventional technology]

This type of color film analyzer, as described in Japanese Patent Application Laid-Open No. 62-141530, is equipped with a long film in which a large number of color films are spliced together using splice tape, and records are recorded on this long film. A television camera (hereinafter referred to as TV camera) sequentially captures multiple frames, and writes the image data of each frame into memory.After writing, the image data of each frame is read out and LATD value (large area average There is a known system that performs gradation conversion and negative/positive conversion based on (transmission density value) and then sends it to multiple CRTs arranged in a row, each displaying a single color image simulating a printed photograph on each CRT. ing. In this device, multiple CRTs display multiple frames of color images in a row, and the color and density of the color images displayed on the central CRT for verification can be manually corrected. For C
A plurality of CRTs on one side of the RT display color images of a plurality of unverified frames, and a plurality of CRTs on the opposite side display color images of a plurality of corrected frames. Therefore, with respect to the color image displayed on the verification CRT, it is possible to determine whether the finish is appropriate by referring to a plurality of color images on both sides of the color image.

[Problem to be Solved by the Invention] The long film is a combination of color films made by many customers, but the frames recorded on the same customer's color films have similar finishes. It is desirable to do so. However, with conventional color film analyzers, it is not possible to determine whether the color images displayed on each CRT are frames recorded on the same color film.

SUMMARY OF THE INVENTION An object of the present invention is to provide a video-type color film analyzer that can determine the range of frames recorded on a single color film.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a splice sensor that detects a joint in a long film and generates a splice detection signal, and a splice sensor that generates image data of a splice frame in response to the splice detection signal. and a means for writing into the image memory, and the joint of the long film is displayed as a splice frame on the image display means.

[Effect]

The splice sensor detects the joint between two color films connected with splice tape when the long film is transported. When the splice sensor outputs a splice detection signal, the splice frame creating means creates image data of the splice frame and writes this into the image memory.

In order to display the splice frame, "zero" is stored in the image memory.
If you write image data of , between the color image of the last frame of one color film and the color image of the first frame of the next color film spliced to this,
A blank frame that does not emit light is inserted. Furthermore, if a color CRT is used as the image display means and red, green, and blue image data are set to the same numerical value, the splice frame will be displayed in gray or white on the image display means. Furthermore, by setting the image data of each color to a different value, it is possible to display a splice frame with desired coloring.

After passing through guide rollers 25 and 26, it reaches the take-up reel 12, and is wound around the outer periphery of this reel. A magnetic floppy 29 storing image data of a reference frame is loaded into the floppy insertion slot 28 . Further, print data is recorded on the punch tape 30 in the form of a bunch code when the verification is completed. This print data includes data common to one color film and individual data determined for each frame. This common data includes the type and size of color film (full size and half size)

In this embodiment, there are 16-frame display, 12-frame display, and 1-frame display, and the display mode can be specified by operating the operation key 39 of the keyboard 34 before the TV camera is opened. In the 16-frame display shown in FIG. 5, there are four columns (A-D) in the vertical direction, each column consisting of four frames.
A total of 16 frames of color positive images 45 are displayed. Here, the A column is the one that was imaged first, and the D column was the one that was imaged last. In the same column, the color image of the frame on the left side is captured first. In the 12-frame display, the color images of the four reference frames read from the magnetic floppy 29 are displayed in column D, and the TV

Displayed in column C. In the one-frame display, one frame of color image is enlarged to the size of four frames and displayed on the display surface 33a.

FIG. 1 schematically shows the color film analyzer of the present invention. A notch sensor 50 attached to the arm 18 detects the notches 113 formed on each frame of the long film 13.

The detection signal of this notch sensor 50 is transmitted to the T10 port 5.
1 to the CPU 52. Since the distance between the notch sensor 50 and the photometric position is known in advance, the notch 113 can be detected by measuring the amount of transport of the long film 13 from the time of notch detection and transporting the long film 13 by this distance. The frame can be positioned at the measurement position. Measurement of the transport amount of the long film 13 is as follows:
For example, this can be done by counting the drive pulses of the pulse motor 53 that transports the long film 13.

A negative mask 54 is placed at the photometry position, and the frames positioned on this are emitted from a lamp 55 and are

Measured by sensor 60 for green and sensor 61 for blue. The scanner 58 includes a lens 62 and an image area sensor 6.
3, photoelectrically converts each point of the image formed on the photosensitive section and outputs it as a time-series signal.

This time-series signal is converted into a digital signal by an A/D converter 64 and then sent to an arithmetic unit 65. This arithmetic unit 65 is composed of an 8-bit microcomputer, and logarithmically transforms the photometric data of each point, and writes the obtained density value into the memory. After this writing, the density value of each point belonging to the pre-designated area is read out, and these are arithmetic averaged to obtain the density value of the area. In this way, density values are obtained for multiple areas, for example, the center of the frame, and the remaining upper and lower half areas excluding this center, and the patterns are classified based on the density value distribution of each area. The density correction amount (common color correction amount for each color) is calculated from the corresponding formula prepared,

The signals output from these sensors 59 to 61 are converted into digital signals by an A/D converter 64, and then taken into the CPU 52 via the I10 port 51.
The correction amount and ND Lafurta value for each color are calculated and stored in the RAM 67.

is driven by. The rotation of this pulse motor 53 is controlled by a motor controller 70, and transports the long film 13 and positions the frames.

The frames that have passed through the photometry position are transported to the imaging position after passing through a buffer loop. In front of this imaging position is a notch sensor 71 attached to the arm 23. A splice sensor 72 is arranged. The notch detection signal output from the notch sensor 71 is sent to the CPU 52 via the I10 baud 51 and is used for positioning the frame as described above. In addition, the splice sensor 72 generates a splice detection signal when it detects the joint of the long film, and sends the splice detection signal to the CPU via the I10 port 51.
Send to 52. When this CPU 52 receives a splice detection signal, it creates image data of a splice frame 46 that displays the position of the joint on the color monitor 33, as shown in FIG.

A negative mask 73 is arranged at the imaging position,
The frames positioned on this negative mask 73 are illuminated with illumination light from a lamp 75 that is diffused by a mixing box 74. This mixing box 74 and lamp 75
Two ND lafurters 76 are disposed between them, and are moved by a pulse motor 77 in opposite directions in a plane perpendicular to the optical path. This ND rough filter 76 is normally inserted at a standard position, is removed from the optical path for extremely overexposed frames, and is further inserted into the optical path for extremely underexposed frames.

Two sets of feed rollers 78 are provided on both sides of the negative mask 73.
．． 79 is arranged and is driven by a pulse motor 80. The rotation of this pulse motor 80 is controlled by a motor controller 0, and the pieces with punches are sequentially positioned at the imaging position. The light transmitted through this positioned frame is
It is reflected by a mirror 82 placed inside the imaging hood 21,
The image is captured by a TV camera 83 placed inside the main body 10 of the testing section. This TV camera 83 has a red signal R1, a green signal G,
Generates blue signal B and synchronization signal 5sync.

These red signal R9, green signal G, and blue signal B are subjected to image processing in the image processing section 84 and then sent to the color monitor 33. The light controller 85 uses the synchronization signal 5yn
The image processing unit 84 creates an address signal etc. based on c.
Control writing in . In addition, the lead controller 86
is controlled by the CPU 52, and creates address signals for reading by the image processing section 84, synchronization signals for sending to the color monitor 33, and the like.

The floppy driver 87 reads the image data of the reference image written on the magnetic floppy 29 and writes it to the image processing section 84 . The puncher 88 is activated at the end of film verification to record print data of common data and individual data on the punch tape 30. ROM
89 is written with fixed data such as printing conditions and programs that control the operations of each part. Work RA
M90 is used for backing up image data and the like.

FIG. 3 shows an embodiment of the image processing section, and since the red signal processing system, green signal processing system, and blue signal processing system all have the same configuration, only the red signal processing system is shown. The red signal output from the TV camera 83 is amplified by an amplifier 95 and then sent to a clamp circuit 96, where the level of the reference signal is set. The red signal output from the clamp circuit 96 is converted into a digital signal by an A/D converter 97 and then sent to a logarithmic converter 98. This logarithmic converter 9 is composed of a look-up table memory, and logarithmically transforms the input signal to convert it into image data proportional to the density value. The CPU 52 is the TV camera 8
3, the table data stored in the bar oMsq is written to the logarithmic converter 98.

The saturation correction circuit 99 is for correcting the difference between the spectral sensitivity of the color paper used in the color printer and the spectral sensitivity of the imaging section of the TV camera 83, and is used to weight the image data of each color. It consists of three lookup table memories 99a and an adder 99b that adds the outputs of these three lookup table memories 99a and outputs the addition result as red image data. Before starting the film verification, the CPU 52
Read each of the three sets of coefficients stored in OM89,
This is changed in steps to create three types of table data for red saturation correction, and write them into the corresponding one of the three lookup table memories 99a.

The saturation-corrected red image data is sent to a demultiplexer.
Image memory 101a designated by 100.

101b. These image memories 101a and 101b have a memory capacity for one screen (one page) displayed on the color monitor 33, and writing and reading are performed alternately. Therefore, for example, while the image memory 101a is being read out one page of image data under the control of the read controller 86, T
New image data captured by the V camera 83 is transferred to the other image memory 101b controlled by the light controller 85.
will be written to. Next, when reading from the image memory 101b is started, writing to the other image memory 101a is started. By using the image memory for two pages in this manner, film inspection is prevented from being interrupted while image data is being captured.

For the image memories 101a and 101b, the CPU 5
An interface 102 is provided in order to read and write image data using the computer 2. Image memory 1
The image data read from either one of 01a and 101b is sent to a gradation conversion circuit 104 via a multiplexer 103, where negative/positive conversion and gradation conversion are performed. This gradation conversion circuit 104 is composed of 16 look-up table memories to correspond to a maximum of 16 frames displayed as one screen, and the gradation conversion circuit 104 is configured with 16 look-up table memories to correspond to a maximum of 16 frames displayed as one screen, and the frame is converted according to the photometry result of the frame and the amount of manual correction. The table data created each time is written by the CPU 52. These table data are created by shifting the reference table data of each color stored in the ROM 89 according to the color correction amount.

The image data subjected to gradation conversion for each frame is converted into a serial signal by a parallel-to-serial converter 105, and then sent to a D/A converter 106.

The red signal converted into an analog signal by the D/A converter 106 is sent to the color monitor 33.

FIG. 4 shows the image memory in detail.

The image memory 101a is composed of four memory blocks, each memory block having four memory areas, and each memory area storing one frame of image data. For example, the memory block in the fourth column is composed of memory areas A1 to A4, and stores image data for one column (four frames) displayed in column A in FIG. Furthermore, the memory blocks in the third column are memory areas A5 to A5.
88, and stores four frames of image data displayed in column B in FIG. In addition, image memory 1o1b
Since they have the same configuration, only the reference numerals are given.

FIG. 6 shows the seams of the long film. The two color negative films 110 and 111 are joined with a splice tape 112. In this way, the long film 13 is created by joining a large number of color negative films with the splice tape 112. This splice tape 1
12 is detected by the splice sensor 72 when the long film 13 is transported. This splice tape 11
2 uses a material different from color negative film, such as white adhesive tape, so it can be detected optically by examining its reflectance or transmittance, or its length and width. .

When the splice sensor 72 detects the splice tape, the CPU 52 creates image data of the splice frame, sends it to the image memory currently being written, for example 101a, and writes it in the memory area corresponding to the display position of the splice frame. Note that the symbols 110a and 1lla are pieces, and the symbol 113 is a notch.

Next, the operation of the above embodiment will be explained with reference to FIG. After turning on the power, operate the alphanumeric keys 38 on the keyboard 34 in order to match the color film analyzer's verification conditions with the color printer's exposure conditions.
Specify the same print channel as the color printer you are using. Next, after inputting the type and size of the film by operating the alphanumeric keys, the display mode, for example, "16 frame display" is designated.

After installing the supply reel 11, pull out a part of the transparent leader bonded to the leading edge of the developed color negative film, hang it on the guide rollers 14 and 15, and then transfer it to the feed roller 16.
Insert it into the This feed roller 16 is driven by a pulse motor 53
Since the sensor is driven by the sensor, a part of the reader is moved toward the photometry position. This transferred tip is passed to a pair of feed rollers 68 and 69 placed on both sides of the negative mask 54, and further passed to a pair of feed rollers 78 and 79 placed on both sides of the imaging position. A part of the leader that has passed the imaging position is pulled out from the feed roller 24, so it is pulled out by the guide roller 25.2.
6, and then wrap it around the outer periphery of the take-up reel 12.

When a portion of the leader is pulled out from the supply reel 11, the developed color negative film is subsequently pulled out and transported toward the take-up reel 12. When the notch sensor 50 detects the notch 113 during this transfer, the drive pulses of the pulse motor 53 are counted and the amount of film feed from the notch sensor 50 is measured. And the first
When the notch is moved by the distance between the notch sensor 50 and the center of the negative mask 54, the pulse motor 53 stops rotating. In this state, the frame with the first notch is positioned at the photometry position.

The frame positioned at the photometry position is illuminated by a lamp 55, and in this state, each point of the negative image is photometered by a scanner 58, and LATD sensors 59 to 61
Accordingly, the LATD values of red, green, and blue are photometered.

When photometry is completed, the pulse motor 53 rotates again to transport the long film I3, positions the second notched frame at the photometry position, and measures the light. Thereafter, the third and subsequent frames are also sequentially positioned at the photometry position and photometered.

When the first frame for which photometry has been completed is transported toward the imaging position, the notch of the first frame is detected by the notch sensor 71. When this notch is detected, the drive pulses of the pulse motor 80 are counted and the film feed amount is measured.

When the long film is fed by a certain amount, the pulse motor 80 stops rotating and the first frame is positioned at the imaging position. While this first frame is positioned at the imaging position, a gray average density value is calculated from the LATD value of each color obtained by photometry of the LATD sensors 59 to 61.
It is determined whether this gray average density value is -. Then, for extremely overexposed frames, the CPU 52
drives the pulse motor 77, moves the ND lafurter 76 out of the optical path, and illuminates the frame with strong illumination light from the lamp 75. Conversely, for underexposed frames, the ND Lafurter 76 is inserted into the optical path to reduce the illumination light.

Before the first frame is positioned at the imaging position,
Since the Lafurter 76 is gJN f'ff, imaging by the TV camera 83 is started immediately after the positioning is completed. The time-series red signal, green signal, and blue signal output from the TV camera 83 are sent to the image processing section 83, where A/D conversion, saturation correction, and storage 1 gradation conversion are performed. That is, as shown in FIG. 3, the red signal is amplified and clamped, and then converted into red image data by the A/D converter 97. This red image data is converted by a logarithmic converter 98 into red image data proportional to the density value, and then sent to a saturation correction circuit 99.

The saturation correction circuit 99 multiplies the three-color image data by a coefficient, adds the multipliers, and outputs the added value as red image data. Red image data is sent to demultiplexer 1.
The image data is sent to the image memory designated by 00, for example, 101a, and written to the first memory area A1 of the 16 memory areas designated by the write controller 85. Similarly, the second and subsequent frames are also sequentially positioned at the imaging position, captured by the TV camera 83, and sequentially written into the memory area A2 and subsequent areas of the image memory 101a.

When the long film 13 is transferred, the splice sensor 72 optically detects the passage of the splice tape 112 and outputs a splice detection signal representing the joint between the color films 110 and 111 as shown in FIG. This is C
Send to PU52. The CPU 52 writes image data with a digital value of "zero" into the memory area to be written next. For example, in the case shown in FIG. 5, memory area A1
The image data of "zero" is written in 1, and the splice frame 46 is displayed as a blank without emitting light.

Then, the image data of the first frame recorded on the next one color negative film is written into the memory area A12.

When 16 frames including the splice frame are imaged and the image data is written into the image memory 101a, reading of the image for one page is completed. In this case, the demultiplexer 100 is switched to the image memory 101b side and reading from the image memory 101a is started. When the image memory 101b enters the write mode, the TV camera 83
The image data of the new frame read in is stored in image memory 10.
1b, and image data is written therein as described above.

When the image memory 101a enters the read mode, the read controller 86 reads image data. This image data is sent to a gradation conversion circuit 104 via a multiplexer 103, where negative/positive conversion and gradation conversion are performed. Since this gradation conversion circuit 104 has a look-up table memory prepared for each frame, the one corresponding to the frame being read out is selected, and the image data is converted using the table data stored therein.

Here, different table data is written in each lookup table memory for each frame. This table data is created by shifting the reference table data according to the density correction amount obtained by photometry by the scanner 58 and the color correction amount obtained by photometry by the LATD sensors 59 to 61.

The gradation-converted image data is converted into a serial signal by a parallel-to-serial converter 105, and then sent to a D/A converter 1.
06, the red signal is converted into an analog signal and the obtained red signal is sent to the color monitor 33.

Similarly, the green signal and the blue signal are read out, and one page containing 16 frames of color images 45 is displayed on the color monitor 33, as shown in FIG. Note that, in reality, the color image 45 of each frame is slightly separated so as not to stick to the adjacent color image, and the space between them is displayed as a white frame.

Since color images 45 of 16 frames simulating printed photographs are displayed on the color monitor 33, it is determined whether these densities and colors are appropriate. Since the splice frame 46 is also displayed at the time of this determination, it is possible to know the beginning of one color negative film. - For boat fishing, it is best to have the same finish for frames recorded on a single color negative film. Therefore, since the range of one color negative film can be known from the splice frames 46, it can be determined whether the colors and densities of these frames are the same.

For a color image that is recognized as not having a good finish, the frame designation key 40 of the keyboard 34 is operated to designate the frame. When a frame is designated, the image data of the designated frame is read from the image memory 101a and written to the work RAM 90 via the interface 102. Among the image data written in the work RAM 90, image data of a specific area where the frame designation cursor 47 is inserted as shown in FIG. 5 is read out to the CPU 52, and this image data is converted into negative/positive (converted into complementary color).
Then, image data for the frame designation cursor 47 is created. The image data of the frame designation cursor 47 created in this way is
The image data is sent to the image memory 101a via the interface 102, the image memory 101a is temporarily set to write mode, and the image data is written into a part of the memory area of the read frame. Since the image data of this written portion is converted into negative/positive in the gradation conversion circuit 104, the frame designation cursor 47 is displayed as a negative image, which is the same as the image recorded on the color negative film. . Furthermore, if you specify a frame by mistake, you can simply operate the clear key. When this clear key is operated, the image data stored in the work RAM 90 is written to the original memory area, and then the color image before the frame designation cursor is inserted and composited is displayed on the color monitor 33.

After specifying the frame, the user operates the color key 35 or the density key 36 to input the correction amount. When this correction amount is input, the table data of the look-up table memory that performs the gradation conversion of the specified frame is updated. Since the image data is converted using this new table data, the color image of the specified frame is displayed with the density or color corrected. If this correction is insufficient, the color key 35 or density key 36 may be operated again. If correction is required for another frame as well, the frame designation key 40 corresponding to this frame is operated. When this frame designation key 40 is operated, the image data of the frame stored in the work RAM 90 is transferred to the image memory 10 via the interface 102.
1a. After this writing, the image data of the newly designated frame is read out from the image memory 101a and written into the work RAM 90, and part of it is converted into negative/positive as described above. As a result, the frame designation cursor 4 that was displayed on the color image of the corrected frame
7 is deleted, and a frame designation cursor 47 is displayed on the color image of the newly designated frame. The density and color of this newly designated frame can also be modified as described above.

With simultaneous printing, the color printer prints each frame one by one, so there is no need to specify the number of copies to print. However, even in this simultaneous printing, if two or more copies are to be printed, it is necessary to specify the number of copies to be printed.

Furthermore, in the case of reprints, it is necessary to specify the reprint frames and their number in response to the customer's order. When specifying the number of prints, the user operates the frame designation key 40 to specify the frame, and then inputs the number of prints using the alphanumeric keys 38 of the keyboard 34. When the number of prints is input, the CPU 52 reads image data from a memory area, for example A8, corresponding to the designated frame and stores it in the work RAM 90. With this work RAM90 ・
The purpose of saving the image data is to display the original color image on the color monitor 33 when the clear key is operated to erase the display of the number of prints, as in the case of the frame designation cursor 47. After storing the image data in the work RAM 90, the CPU 52 writes data on the number of prints into the memory area A8. Since this print number data is read together with the image data, it is displayed on the color monitor 33 with the print number 48 embedded in a part of the color image. In this embodiment, numbers to be displayed by emitting light are inserted into a square blank which does not emit light.

Further, when printing the same number of frames for all frames of one color film, the splice frame 46 at the beginning of one color film is specified using the frame designation key 40. Next, when the number of prints is input, the data of the number of prints is written into the memory area All that stores the M image data of the splice frame 46. By writing this number of prints, as shown in Figure 5, the splice frame 4
The common print number 46a is displayed approximately in the center of 6.

Furthermore, although most of the frames of one color film have the same number of prints, it may be desirable to print some of them with different numbers. In this case, it is sufficient to designate the splice frame 46 and input the common number of prints for one color film, and at the same time designate the frame to be changed and input the number of individual prints. In this way, if you specify the number of prints for each frame and the total number of prints twice, both of these data will be stored in the RAM 67.
and output to punch tape 30.

For out-of-focus frames or frames for which the main image does not exist due to erroneous photography, the frame is specified using the frame specification key 40, and then the operation key 39 is operated to input that printing is not required. When this print is not required, the image data of memory area A2 corresponding to this frame is stored in the work RAM 90, a part of the image data is extracted and converted into negative/positive, and then it is stored in memory area A2. Write. As a result, as shown in FIG.
9 is displayed.

If it is recognized that all the frames are finished well, the next page key 41 is operated. This next page key 4
When 1 is operated, 1 stored in the image memory 101b is
Six frames of image data are read out and displayed on the color monitor 33 as described above. The film inspection can be performed on one page of frames displayed on the color monitor 33 as described above. During this film inspection,
Transfer of the long film 13 is started, the 16 frames recorded thereon are sequentially imaged by the TV camera 83, and the obtained image data is written into the image memory 101a.

When the film verification is completed for all the frames recorded on the long film 13, the print data stored in the RAM 67 is recorded on the punch tape 30 by operating the operation key 39.

That is, after the punch data representing the splice frame 46, common data such as the type and size of the color film and the number of prints for one color film are recorded as a punch code, and after this, the exposure correction data of the frame, the number of prints of the frame, etc. Individual data such as whether printing is unnecessary is recorded sequentially for each frame.

In this way, the data on the number of prints is recorded in the puncher 130 for each color film and for each frame, so the number of prints may be specified twice depending on the frame. However, this overlapping designation can be resolved by setting a control program in the printer that gives priority to the number of individual prints designated for each frame. In addition, the exposure correction data is
This is the sum of the amount of correction automatically calculated by the scanner 58 and the amount of manual correction manually entered.

When printing a photo, when the punch tape 30 is set in the printer, the common data is read from the punch tape 30, and when each frame is printed one after another, the individual data of the frame to be printed is read, and these data are read. Operation of the printer is controlled. In addition, the printer has red and green colors.

Since a blue LATD sensor is provided, the LATD value of each color is measured by these sensors.

The exposure amount for each color is measured from these LATD values, and by adding the exposure correction data read from the punch tape 30, the exposure amount during photographic printing is adjusted for each color.

When displaying 12 frames, the keyboard 34 is operated to specify this display mode. After specifying the mode, the magnetic floppy 29 is set and the four reference images written therein are read out and written into the work RAM 90. After this writing, the image data of the reference image is read from the work RAM 90, and the memory areas A13 to A16 and B13 corresponding to column D are displayed on the color monitor 33.
-Write in B16 respectively. Therefore, the areas in which image data of frames captured by the TV camera 83 are written are memory areas A1 to A12. B1 to B12,
Twelve frames are read by the TV camera 83 and displayed in columns A to 0 of the color monitor 33.

When inspecting the film, the finish can be checked by referring to the four reference images displayed in column D. Note that if a frame is specified using the frame specification key 40 because manual correction is required, if you shift the line containing this frame to the 0 column position, it will be displayed next to the reference image, so it will be Comparison becomes easy.

Even in the case of single-frame display, the user first operates the keyboard 34 to specify the display mode. In this one-frame display, imaging and display are performed one frame at a time, and a one-frame color image written to the image memory, for example 101a, in read mode is displayed in a large size in an area corresponding to four frames in the center of the screen. is displayed.

This size expansion is achieved by electrically increasing the magnification through interpolation processing, as well as by shortening the sampling period of the A/D converter 97.
Image data for each frame may be created. For example, 1
In the case of 6-frame display, use the frame designation key 40 to correct the color.
When specifying a frame with , it is convenient to enlarge and display this frame.

In the embodiment described above, color and density correction is performed by the gradation conversion circuit 104, but the lamp 75 and the mixing box 74
Cyan, magenta, and yellow light control filters may be arranged between the two and the amount of insertion into the optical path may be adjusted to perform color and density correction. Furthermore, this dimmer filter performs rough correction on color and density, and the gradation conversion circuit 104
It is also possible to make detailed corrections. In addition, splice frames can be created by arbitrarily determining the value of image data.
It is possible to emit light at a desired brightness or display in a desired color. Note that the present invention can also be applied to color reversal films.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when the splice sensor detects the joint of each color film, the image data of the splice frame is written into the image memory, so that it is displayed on the image display means. You can see the joints in the color film from the spliced frames. Therefore, to what extent is 1 out of multiple color images?
Since it is known whether the frame was recorded on the color film of a book, it is possible to perform color and density correction on the frames of the same color film so that the finished image is the same. Furthermore, when recording film inspection data on a bunch tape, etc., data representing the splice frame is recorded, and then the type and size of the film are recorded so that these can be identified as common data for one color film. be able to.゛
