Abstract

PURPOSE:To display in the same size in either of 135F and 135H by executing an electric magnification conversion at the time of fetching picture data. CONSTITUTION:A TV camera 44 picks up the image of a frame recorded on a color film and the picture data of respective obtained picture elements on a picture memory 71 through a buffer memory 72. At this time, to the frame of 135F (135 full size), the picture elements are thinned out in the interval of a constant number horizontally and vertically in a buffer memory 72 to fetch picture data. The picture elements are thinned out in the interval of the constant number only in a vertical direction to the frame of 135H (135 half size) to convert the address of a horizontal and a vertical direction and fetch the picture data with a picture rotated by 90 deg.. This address conversion is executed by an address converting circuit 84.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an image data importing method for importing image data of frames recorded on color film, and more specifically, to a method for importing image data of frames recorded on color film, and more specifically, to a method for importing image data of frames recorded on color film. The present invention relates to a method for displaying full-size frames and half-size frames in the same size on an image display means.

[Conventional technology]

A video color film analyzer is used to predict the finish of frames recorded on color film using a video system. The frames recorded on color film are captured by a television camera (hereinafter referred to as a TV camera).
The image data of each pixel is written into the image memory. After capturing this image data, the image data is read out from the image memory, subjected to various image processing, and then sent to an image display means, for example, a color CRT, where it is displayed as a color positive image on its display surface. By observing the color image of the frame displayed on the color CRT, the operator can judge whether the finish will be appropriate or not. Specify the exposure correction data for

In addition, as a display form of a color image, for example,
As described in No. 2-141530, a plurality of color CRTs are arranged in a row and one color image of one frame is displayed on one color CRT, and the other is, for example, European Publication No. 0108158. As described in , there is a color CRT that displays a plurality of color images arranged in a matrix on one color CRT.

[Problems to be Solved by the Invention] In the conventional color film analyzer described above, the color image of a 135-type full-size (hereinafter referred to as 135F) frame is normally displayed on a TV so that it almost matches the effective display surface of a color CRT. The camera's optical magnification is adjusted. For this reason, the half size of the 135 type (hereinafter referred to as 13
Since the screen size of a 5H frame (referred to as 5H) is half that of 135F, when this frame is captured, a color image will be displayed in a small size. This makes it difficult to observe color images, and also results in the inability to effectively utilize the memory capacity of the image memory and the display surface of the color CRT.

Generally, image size adjustment (magnification conversion) is performed optically using a zoom lens, etc.;

A pulse motor, a lens position detection sensor, etc. are required, which is disadvantageous in terms of cost when there are only a few different sizes, such as color films.

An object of the present invention is to provide an image data importing method that performs electrical magnification conversion when importing image data so that both ζ, 135F and 135H frames can be displayed in the same size. It is in.

[Means to solve the problem]

In order to achieve the above object, the present invention captures a frame recorded on a color film with a television camera, and captures the image data of each pixel into an image memory.
For frame F, image data is taken in by thinning out pixels at regular intervals in the horizontal and vertical directions, and 135H
The frames are thinned out at regular intervals in the vertical direction, horizontal and vertical address conversion is performed, and the image data is captured with the image rotated 90 degrees.

If the number of pixels is increased, the resolution of the color image displayed on the image display means will be reduced. In order to suppress this drop in resolution and to keep the number of pixels the same for the 110 type, which is the second most widely used type after the 135 type,
It is best to thin out to 1/2. In addition, using a buffer memory, for the 135H frame, image data of pixels thinned out in the vertical direction is written into the buffer memory once, and then the image data is transferred from the buffer memory by exchanging addresses in the horizontal and vertical directions. It is preferable to read the image data and write the read image data to the image memory.

[Effect]

In the present invention, since the magnification is electrically converted when image data is taken in, and both frames of 135F and 135H have the same number of pixels, the magnification can be easily converted and displayed in the same size on the image display means. be able to. Furthermore, the image memory and the image display means can be effectively utilized.

After this calculation, the density values of each point belonging to the pre-designated area are read out, and the density values of the area are determined by arithmetic averaging of these values. 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. A density correction amount (color correction amount common to each color) is obtained from a correspondingly prepared arithmetic expression, and this is written into the RAM 29.

The red color sensor 22. The green sensor 23 and the blue sensor 24 are for measuring the LATD value of the positioned frame, and a lens is placed in front of it. The signals output from these sensors 22 to 24 are converted into digital signals by the A/D converter 27, and then taken into the CPU 15 via the I10 port 14, where the correction amount and ND filter value for each color are calculated. Calculated. These color correction i and ND filter values are written into the RAM 29.

The frames that have passed through the photometry position are transported to the imaging position after passing through a buffer loop. A notch sensor 32 is provided in front of this imaging position to position the frame at the imaging position.

A negative mask 33 is arranged at the imaging position, and the frames positioned on this negative mask 33 are illuminated with illumination light from a lamp 35 that is diffused by a mixing box 34. Two ND filters 36 are arranged between the mixing box 34 and the lamp 35, and are moved by a pulse motor 37 in opposite directions in a plane perpendicular to the optical path.

This ND filter 36 is normally inserted at a standard position, is withdrawn from the optical path for extremely overexposed frames, and is further inserted into the optical path for extremely underexposed frames.

On both sides of the negative mask 33, there are feed rollers 3 of 2.1.

1, the rotation is controlled and the notched frames are sequentially positioned at the imaging position. The light transmitted through this positioned frame is reflected by a mirror 43 and then imaged by a TV camera 44.

This TV camera 44 has a red signal R1 and a green signal G.

Generates blue signal B, synchronization signal 5ync, and field signal. These red signal R1 green signal G.

After the blue signal B is subjected to image processing in the image processing section 45,
The image is sent to the color monitor 46. The color monitor 46 is composed of, for example, a color CRT, and displays a plurality of color images arranged in a matrix on its display surface 46a.

That is, as shown in FIG.
In D), each line consists of 4 frames. Here, row A is the color image of the frame imaged first, row D is the color image of the frame imaged last, and within the same row, the color image of the frame on the left side is imaged first.

The color key 51 consists of a cyan key for correcting cyan, a magenta key for correcting magenta, and a yellow key for correcting yellow, and each color key is composed of a plurality of keys with different correction amounts in stages. has been done. The density key 52 is for correcting the density, and a plurality of keys with different correction amounts are arranged in one row. The operation key 53 is used to instruct the start of verification, printout of correction data, and the like. The alphanumeric keys 54 are used to set print conditions and input data.

The frame specification key 55 is used to manually specify the frame to be corrected, and there are 12 frames corresponding to each frame.
Consists of keys. The next page key 56 is used to switch the display on the color monitor 46 to the next page. The size specification key is used to input the size of the color film. Note that color film has a DX code printed on the side that indicates the type of film, so if a DX sensor is placed on the path of the long film 10, the film size can be automatically input. There is no problem even if it is a long film in which 135F, 135H, etc. are mixed.

The puncher 60 is actuated at the end of film verification;
Exposure correction data (color correction ffi, 'a degree correction amount) is recorded in the bunch chi 161. Fixed data such as print conditions and programs for controlling the operations of each part are written in the ROM 62.

FIG. 2 schematically shows 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 44 is sent to the amplifier 6.
5 and then sent to a clamp circuit 66, where the level of the reference signal is set. The red signal output from the clamp circuit 66 is converted into a digital signal by an A/D converter 67 and then sent to a logarithmic converter 68. This logarithmic converter 68 is configured with a look-up table memory, and logarithmically transforms the input signal to convert it into image data proportional to the density value. The CPU 15 is a TV camera 44.
The table data stored in the ROM 62 is written into the logarithmic converter 68 before imaging starts.

The saturation correction circuit 69 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 unit of the TV camera 44, and is used to weight the image data of each color. It consists of three lookup table memories 69a and an adder 69b that adds the outputs of these three lookup table memories 69a and outputs the addition result as red image data. Before starting the film verification, the CPU 15
Read each of the three sets of coefficients stored in OM62,
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 69a.

In response to a switching signal from the CPU 15, the selector 70 sends image data to the image memory 71 when the long film lO is 135F or 110 type, and
is sent to the image memory 71 after passing through the buffer memory 72. This buffer memory 72 is for rotating the 135H image by 90 degrees. Here, one frame is composed of 256 x 256 pixels (64K in total), and one gradation of the three primary colors of one pixel is expressed with 8 bits, so the buffer memory 72 has 8 64K pixels.
*1 bit RAMs 721 to 728 are used.

The image memory 71 is composed of a plurality of memory boards according to the level of gradation expression, and each memory board is composed of four blocks of RAM corresponding to each row A to D of the color image matrix. In this embodiment, eight memory boards 711 to 718 are used, and one memory board is composed of four RAMs (256K x 1 bit) ad. The RAM 711a is divided into four memory areas A1 to A4, and each memory area A
1 to A4 store one frame of image data. other R
The memory area of AM71 l b to 711 d contains the 6th memory area.
Numbers are given using alphabetical characters corresponding to the rows in the figure. Note that it is also possible to configure one row by combining four 64K×1-bit RAMs. Alternatively, two or more image memories may be provided, and when one of them is in the write mode, the remaining one may be used in the read mode. By using an image memory for two or more pages in this way, it is possible to eliminate interruptions in film inspection during the capture of image data.

The image data read from the image memory 71 is sent to a gradation conversion circuit 73, where negative/positive inversion and gradation conversion are performed. This gradation conversion circuit 73 is composed of 16 lookup table memories to correspond to a maximum of 16 frames displayed as a matrix, and uses the table data stored in each lookup table memory. The image is then processed. These lookup table memories are created by shifting reference table data according to the photometric results of the frames and the manual correction amount. The image data subjected to gradation conversion for each frame is sent to the D/A converter 74. This D/A converter 74
The red signal converted into an analog signal is sent to the color monitor 46.

In order to write image data into the buffer memory 72 and image memory 71, four address signal generation circuits 78 to 81 are provided. These address signal generation circuits 78, 80, and 81 use the synchronization signals (Hsync, Vsync) and field signals output from the TV left camera 4, and the clock signal of the clock generator 82 to generate the TV left camera 4. The address signal is generated in synchronization with the output of the video signal from. 135H, the address signal of the address signal generation circuit 78 is sent to the selector 8 in order to temporarily drop the image data into the buffer memory 72.
3 to the buffer memory 72. When image data is transferred from the buffer memory 72 to the image memory 71, the address signal output from the address signal generation circuit 79 is sent to the address conversion circuit 84.

This address conversion circuit 84 rotates the image by 90 degrees by exchanging the horizontal and vertical addresses.

Note that the selector 83 selects an address signal using a switching signal from the write controller 47.

The selector 85 is controlled by the write controller 47 and selects one of the three address signals output from the address signal generation circuits 79 to 81, respectively. This selected address signal is sent to the adder 86, added to the start address output from the start address designation circuit 87, and then sent to the image memory 71 via the selector 88.
sent to. This head address designation circuit 87 is for designating which of the 16 memory areas image data is to be written. The selector 88 is the adder 86
Either one of the write address signal output from the address signal generation circuit 89 and the read address signal output from the address signal generation circuit 89 is selected.

Next, film verification will be explained. First, after setting the developed long film 10, in order to match the test conditions of the color film analyzer and the exposure conditions of the color printer, press the alphanumeric key 5 of the keyboard 50.
4 to specify the same print channel as the color printer you are using. Next, the user operates the size designation key 57 to designate a film size, for example, 135F.

When the start of film inspection is instructed, the long film 10 is transported in the direction of the arrow, and during this transport, a notch is detected by the notch sensor 13. By controlling the film feed amount based on this notch detection, the frame with the first notch is positioned at the photometry position. The frame positioned at the photometry position is illuminated by the lamp 19, and in this state, each point of the negative image is photometered by the scanner 21, and the LATD sensors 22 to 24 measure the red, green, and blue L. The ATD value is photometered. When photometry is completed, the pulse motor 16 rotates again to transport the long film 10, positions the second notched frame at the photometry position, and measures the light. Below, the third
The 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 32. The film feed amount is controlled based on this notch detection, and the first frame is positioned at the imaging position. While this first frame is positioned at the imaging position, it is determined whether it is super overexposed or super underexposed from the photometry results of the LATD sensors 22 to 24, and whether the super overexposed frame is teeth,
The CPU 15 drives the pulse motor 37, moves the ND filter 36 out of the optical path, and illuminates the frame with strong illumination light from the lamp 35. Conversely, for underexposed frames, an ND filter 36 is inserted into the optical path to attenuate the illumination light.

Before the first frame is positioned at the imaging position,
Since the filter 36 has been adjusted, imaging by the TV left camera 4 starts immediately after positioning is completed. The time-series red signal, green signal, and blue signal output from the TV left camera 4 are sent to the image processing section 45, where they are subjected to A/D conversion, saturation correction, and storage 9-gradation conversion. That is, as shown in FIG. 2, the red signal is amplified and clamped, and then converted into red image data by the A/D converter 72. This red image data is processed by a logarithmic converter 73
After converting to red image data proportional to the density value,
The signal is sent to the saturation correction circuit 74.

The red image data corrected again by the saturation correction circuit 74 is sent to the image memory 71 via the selector 70.

The address signal generation circuits 78 to 81 operate in synchronization with the image processing of the red image, but since the color negative film being imaged is 135F, the selector 85 takes out the address signal from the address signal generation circuit 79 and outputs it. Send to adder 8G.

When capturing the first frame, the start address designation circuit 8
7 outputs an address signal for the origin position of the first memory area A1 of each memory board 711-718. This address signal of the origin position and the address signal taken out from the selector 85 are added, and the obtained address signal is sent to the image memory 71 via the selector 88. Since the image data for one pixel is 8 bits for each color, red image data is written one bit at a time to eight memory boards 711 to 718 simultaneously designated by the address signal. Thereafter, the red image data of each pixel input via the selector 70 is written into the image memory 71 in the same manner. Note that green image data and blue image data are also written to the image memory in the same way.

When writing of the image data for the first frame is completed, the pulse motor 40 rotates again to position the second frame at the imaging position. Further, the light controller 47 is
A signal indicating the number of captured frames is sent to the start address designation circuit 8.
Send to 7. This head address designation circuit 87 outputs the head address signal of the second memory area A2 of each memory board 711 to 718, and writes the image data of the second frame therein.

The 16 frames of image data sequentially read by the TV left camera 4 in this manner are written into the image memory 71. After reading this image, the read controller 48 sets the image memory 71 to read mode. Then, the address signal output from the address signal generation circuit 89 is extracted by the selector 88 and sent to the image memory 71.

According to this address signal, the image data written in the image memory 71 is read out and sent to the gradation conversion circuit 73. Since a look-up table memory is prepared for each frame, the gradation conversion circuit 73 selects a look-up table memory corresponding to the frame being read, and converts the image data using the table data stored therein. Here, the look-up knob table memory for print frames is filled with different table data 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 21 and the color correction amount obtained by photometry by the LATD sensors 22 to 24.

The gradation-converted image data is converted into an analog signal by the D/A converter 73, and the obtained red signal is sent to the color monitor 46. Similarly, the green signal and the blue signal are read out, and as shown in FIG.
is displayed on the color monitor 46. In fact, 16
The color images 92 are spaced apart a little so as not to stick to adjacent color images, and the space between them is displayed as a white frame.

The 16-frame color image 92 is observed to determine whether the finish is appropriate.

Then, for a color image that is recognized as having a poor finish, the user operates the frame designation gear 55 on the keyboard 50 to designate a frame. Note that when this frame specification is performed, the frame specification cursor (
(not shown) is displayed. Next, the color key 51 or the density key 52 is operated 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 51 or density key 52 may be operated again.

If it is recognized that all the frames are finished well, the next page key 56 is operated. This next page key 5
6 is operated, an image is captured by the TV camera 44 and a simulated color image of the print image is displayed, and the film inspection can be performed on these 16 frames.

When the film verification has been completed for all the frames recorded on the long film 10, by operating the operation key 53, the exposure correction data for each frame stored in the RAM 29 is recorded on the punch tape 61. Ru. This correction data is the sum of the amount of correction automatically calculated by the scanner 21 and the amount of manual correction manually entered. When printing a photo, if the punch tape 61 is set in the printer, the correction data is read from the punch tape 61.
It is added to the LATD value of each color measured by the LATD sensor built into the printer, and the exposure amount for photo printing is determined for each color.

135H, the size designation key 57 is operated to input the film size. In this case, the image data of the frame read from 135H is written into the buffer memory 72 by the address signal of the address signal generation circuit 78. After writing into the buffer memory 72, the address signal from the address signal generation circuit 79 is sent to the address conversion circuit 84, where the horizontal address and vertical address are exchanged. Image data is read out from the buffer memory 72 using this orthogonally transformed address signal, and the address signal generation circuit 79
The data is written to the image memory 71 specified by the address signal.

In this way, in 135H, the image data of each frame is written into the image memory 71 via the buffer memory 72. 16
After the frame image data is aged, the image data is read from the image memory 71 and sent to the color monitor 46. On this color monitor 46, 16 color images are arranged in a matrix and displayed in the same size as 135F. However, in this 135H, since the addresses are orthogonally transformed, each color image is rotated by 90 degrees and is oriented horizontally.

When performing film verification on 110 type color negative film, the address signal generation circuit 81 is activated, and the address signal output from this circuit specifies the address of the image memory 71, and the image data read by the TV camera 44 is is written into the image memory 71.

Next, the relationship between the effective image capture screen of the TV camera and the image memory will be explained with reference to FIGS. 3 to 5. Effective imaging screen (hereinafter simply referred to as imaging screen) 10 of the TV camera 44
0 includes 512 scan lines in the vertical direction (V). Here, even numbers represent scanning lines of 0 field, and odd numbers represent scanning lines of 1 field (increment field). Further, sampling is performed 512 times for one scanning line. Therefore, the imaging screen has 512 pixels in each of the horizontal and vertical directions, and one frame image is composed of 256 pixels in total.

On the other hand, since one memory area of the image memory 71 is made up of 64 bits, it is possible to store 64 pixels. Therefore, in step 135H, image data of one pixel taken horizontally and vertically among the 256 pixels imaged by the TV camera is taken into the image memory 71. That is, for image data of 0 field,
The image data of each pixel is extracted by thinning out one pixel at a time in the horizontal direction. This pixel thinning is performed by the address signal generation circuit 80. As a result, as shown in FIG. 4(A), image data of 64 pixels, which are even numbers, are written in the memory area of the image memory 71 in both directions. Here, X indicates the address in the horizontal direction, Y indicates the address in the vertical direction, and the numbers in parentheses indicate the image capture screen 1.
It represents the direction at 00.

Since the magnification of the optical system is adjusted so that the captured screen of the TV camera 44 and the frame of 135F match, in 135H, the hatched area in FIG. 3 is the size of one frame. In this hatched part, pixels in the horizontal direction are from Nth to (N+255)th. The address signal generation circuit 78 processes the image data of the O field from the Nth to (N+255) without thinning out pixels in the horizontal direction.
Take out all the pixels in the buffer memory 7.
Write in 2. In other words, since the 135H does not perform ink lace, the image becomes elongated in the vertical direction, so by compressing it to 1/2 in the vertical direction and leaving it as is in the horizontal direction, the image can be compressed without distortion. , 256 pixels in the horizontal and vertical directions, a total of 64 pixels, and the image data of these pixels is written into the buffer memory 72.

The image data written to the buffer memory 72 is
The address is orthogonally transformed, read out, and written into the image memory 71. Therefore, as shown in FIG. 4(B), an image composed of 64 pixels is captured into the image memory 71 in a state rotated by 90 degrees. Note that since the aspect ratio of the color monitor 46 is 3:4, when the image is rotated by 90 degrees, a slight elongation occurs in the vertical direction of the color monitor 46. Therefore, in order to eliminate this delay, when writing image data to the buffer memory 72,
It is preferable to thin out one pixel out of every five pixels in the horizontal direction.

For 110 type color negative film, the range shown by cross hatching in FIG. 3 is the size of one frame. This range is from the Nth horizontally to (N+255)
up to the Mth in the vertical direction (N+255)
up to the th. Therefore, both horizontal and vertical directions are 2.
Since there are 56 pixels, there is no thinning in both directions.
The image is written into the image memory 71 as is.

As mentioned above, in 135F, pixels are reduced by 1/2 in both directions.
By thinning out to 2, the number of pixels is compressed to the same number as the 110 type, and in the 135H, the number of pixels in the vertical direction of the image capture screen is reduced to 1/2, so the number of pixels is also the same as the 110 type. Therefore, for all of the 135F, L35H, and 110 types, one frame of color image is displayed in the same size on the color monitor 46.

FIG. 5 is for explaining writing of pixels. 1
For 35F and 110 types, it represents a pixel written to the image memory 71, and for 1' 35H, it represents a pixel written to the buffer memory 7.
It represents the pixel written to 2.

In the embodiment described above, color images of a plurality of frames are arranged and displayed in a matrix, but the present invention can also be used when displaying a single frame in a large size on a color monitor.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when writing image data to the image memory, the same thinning is performed in the horizontal and vertical directions for 135F, and only in the vertical direction for 135H. Since I decided to thin out the
Both 135F and 135H can capture image data of the same number of pixels into the image memory. Therefore, image memory can be used effectively, and 13
5F and 135H can be displayed in the same size on the image display means.

Furthermore, if the thinning is set to 1/2, the number of images will be the same as the 110 type frames, so the 110 type frames can also be displayed in the same size. Furthermore, since a buffer memory is used for 135H, orthogonal transformation of the address can be performed reliably.

Claims (3)

[Claims] (1) When capturing images of frames recorded on color film with a television camera and importing the image data of each pixel obtained into the image memory, for 135 full-size frames, images are captured at fixed intervals in the horizontal and vertical directions. For 135 half-size frames, pixels are thinned out at regular intervals in the vertical direction, and horizontal and vertical address conversion is performed to rotate the image by 90 degrees. An image data importing method characterized in that the image data is imported. (2) The image data importing method according to claim 1, wherein the pixels are thinned out every other pixel. (3) For the above-mentioned 135 half-size frames, the image data of pixels thinned out in the vertical direction is written into the buffer memory once, and then the image data is read out from the buffer memory by exchanging addresses in the horizontal and vertical directions. 3. The image data importing method according to claim 1, wherein the read image data is written into an image memory.
