Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides high-quality color film and/or color separation plates from a screen recorded on a videotape or the like and arbitrarily selected from a continuous video signal such as a nine television broadcast signal. The present invention relates to a video plate-making device for creating video plates.

Due to the remarkable development and spread of video technology in recent years and changes in publishing trends due to the diversification of printed materials, it would be possible to use a predetermined screen from the serial film information recorded on video tapes for photographs, printed manuscripts, etc. The situation is now such that the benefits can be obtained. In other words, compared to the previous method of film manipulation using a still camera, it is freed from the constraints of rapid reporting, photo opportunities, shutter sounds, flashlights, and low-brightness conditions, and at the same time provides various advantages. For example, it is possible to create photographs or printing plate materials directly from film information recorded on video tapes, etc., or to create NT8C or RGII signals from movie film using a telecine device, and then print directly from this. Compared to conventional methods, it is possible to publish at a lower cost than with conventional methods.

However, if you want to use the Eirin information recorded on a conventional videotape as a printed manuscript, you can set the videotape on a playback device, display the continuous Eirin on the screen in slow or stop playback, etc. A film original is created by photographing a desired image with a still camera while observing the screen, and then color separation plates are created from the film original using a plate making device such as a color scanner. Therefore, the quality of the printed document depends on the resolution of the television.

In Totoro, our country's color television broadcasting is MTEIO.
Regardless of the size of the TV, 625 viewing lines form the /li screen.

The image quality of the #, #, and # frames is extremely poor in terms of resolution, etc., compared to general color films. Furthermore, in the method of selecting a predetermined screen from a continuous video film and shooting it with a still camera, in order to improve the quality of the image, the color temperature of the KtI color cathode ray tube, the coloring characteristics and density range of the KGB phosphor, the color temperature of the color film, Due to the mismatch between the characteristics of the coloring material and the density range, there is a problem in that it is necessary to insert a special color temperature conversion filter in front of the camera and to adjust the hue, contrast, etc. of a one-color monitor. However, these corrections alone do not necessarily provide a satisfactory color tone.

Furthermore, the number of television scanning lines has a great influence on the quality of dissolution, and when a camera is photographed with an accurately focused camera on a film projected on a color cathode ray tube, these scanning lines are clearly recorded as horizontal stripes on the film. be done. The nine scanning lines recorded on this film cause moiré during the plate-making process, so a photographic technique is required to erase the scanning lines.

For example, K obtains the desired eirin from a continuous eirin with little movement.
Normally, scanning lines are erased by exposing several frames onto a single film while playing back or slow playing back, but since the scanning lines cannot be completely erased, the focus of the image is slightly shifted. However, this method has the disadvantage that it is difficult to accurately photograph the desired screen, and the screen may be blurred. Therefore, in order to obtain the desired video signal from a continuous video signal with large movements, it is necessary to perform stop playback.With a normal color inch VTR, only the L field video signal is reproduced in the case of stop playback, and the video signal projected on the CRT is The vertical resolution is halved in the former case, and a more difficult scanning line erasure photographing technique is required than in the former case. In such cases, the resolution of color film is generally y/
Since this was after the double rudder, a photographing method was used that took advantage of the resolution limit of color film. That is, the scanning lines are erased by photographing the desired image on the cathode ray tube in such a reduced size that the scanning lines cannot be distinguished. Therefore, since the video footage, which originally has poor image quality, is shot on very small size film, the final print size is limited to A6 to M7 size, and larger sizes cannot be expected to have any commercial value. 9. Workability deteriorates considerably due to page layout and enlarged plate making of small-sized paper.

Various techniques have been proposed to solve the above-mentioned nine problems. In the tlj publication, a frame memory device, means for sequentially reading out signals from the memory in synchronization with the scanning speed of a scanner, and an NT

In this device, the above-mentioned problems can be solved by effective Kj
However, since the device configuration is all online, repeating slow playback, stop playback, etc. of the video tape recorder to get the desired screen will shorten the life of the video tape recorder and further damage the video tape recorder. It would be dangerous if the friction caused by the playback head damaged a customer's valuable video tape. Furthermore, since all of the components are online during the repair work, the videotape editing work and the signal conversion processing work cannot be performed independently, which poses problems in terms of workability and efficiency.

This device also includes a time base corrector that electrically corrects image jitter and dropouts, a noise reducer that removes noise other than the image signal, and an iir.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a video image plate-making apparatus that obtains high-quality Oi1i quality suitable for plate-making printing from a low-quality television signal.

In a video image plate-making device that selects an arbitrary screen from a continuous video signal such as a television video signal, performs various processing, and then creates a high-quality color film or color separation plate. Then, the continuous video signal recorded on the original videotape is reprinted on the master videotape together with the time code without degrading the image quality, and after that, when a desired screen is selected from the master videotape, it corresponds to the selection screen. A videotape editing section that records time records on a recording medium such as a paper tape, and this videotape editing r are configured offline, and the recording medium and! information on the star tape>, an automatic selection playback section that automatically extracts the selection screen, and an image quality improvement processing section that performs time lag correction of the video Eirin signal, noise removal included in the Eirin signal, and contour enhancement section 11. By separating brightness and color signals suitable for high-quality images, converting them into RGB signals, RGM, and () each signal can be adjusted independently, and color and gradation can be adjusted without losing balance. A correction section that adds correction processing and a 0RG that digitizes the KGB signal.
BO An image comprising an interpolation unit that stores each digital image information in a frame memory, sequentially calls out scanning line information of odd fields and scanning line information of even fields, and interpolates the information between them by two-dimensional interpolation. The signal conversion processing unit performs image quality improvement processing on each of the nine ROBs.
The present invention is characterized by comprising an output section that outputs the signal to a color film production device that produces a color film and/or a color scanner that produces high-quality color separation plates.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the videotape editing section of the present invention. Currently, the video tapes provided by customers are generally 5/4 inch wide U-Hatla video cassette tapes, and the nine original cassette tapes provided are set in a 3/4 inch video tape recorder Afterwards, it is possible to select the screen to be used by repeatedly operating the automatic electronic editing unit's slow playback and stop playback knobs while observing the monitor screen. However, from among the actual movie serials, the iiiir desired by the client
Choosing m accurately is a rather difficult operation.

In particular, repeating slow playback, stop playback, etc. of a video tape recorder in order to capture a photo-opportunity screen will shorten the life of the video tape recorder. You may also damage the valuable video tapes of your customers. In order to solve the above-mentioned problems, in the present invention, as shown in FIG. Via the generator, reader san! It was preset in an inch helical scan video tape recorder J and rerecorded on a 91 inch wide videotape L. In addition to the video track for recording video information and the audio track for recording audio information, the 1-inch wide videotape is made by passing it through a time code generator and a reader, which has a time code track for recording time code. Time code generator,
The time code generated from the leader reference is continuously recorded on the 1-inch videotape in correspondence with 1 frame of video information. Using this time suit, rounding and screen extraction, which allow customers to specify the screen they want to use for printing, can be performed accurately and in a short time. 9. When re-recording, the automatic electronic editing unit J controls the playback stop of the 5A-inch and 1-inch helical scan reduction video tape recorders, and the re-recording status is displayed on the display monitor 7 via the video switcher 1. It can be observed.

Therefore, if it is not necessary to re-record the entire s/4-inch wide videotape provided by the customer, it is possible to re-record only the necessary portions while watching the video on the display monitor 7.

The 1-inch wide videotape l re-recorded as described above is once rewound on a 1-inch helical scan video tape recorder j and played back after death. Playback is performed by operating the slow playback and stop playback knobs of the automatic electronic editing unit 3.

The video information can be viewed on a display monitor 7 via a video switcher 6. This display monitor has a built-in Y/C separation decoder and uses a high-resolution cathode ray tube, so it can provide better image quality than ordinary monitors. Therefore, Ij of re-recording
While replaying i on the display monitor γ, select the desired screen at any time based on the customer's instructions for printing or use in the customer's presence, and at the same time specify the 7 frames on the screen selection instruction console 10. By pressing the switch, the time code read by the time code generator and reader reference and the time code on the nine selection screen will be displayed at the time code readout section t.
is registered in a part of the memory. In this way, the frame registration for all the necessary screens on the re-recorded 91-inch wide video tape 10 is completed, and after that, the screen selection instruction operation console 10
Press the frame registration completion switch. Then, the registered time code information is sequentially read out from the time code reading section t, converted into ;-code, and outputted from the paper tape puncher/l on paper tape/JK. . Note that the system control for this part is controlled by a micro-punviewer.

Nine, 1 inch helical scan lid video tape recorder! This is a method of re-recording the video cassette tapes provided by the customer without deteriorating the quality as much as possible, but if it is necessary to reduce costs, it is possible to re-record the video cassette tapes provided by the customer without deteriorating the quality as much as possible. For example, if you select a 1-inch video tape recorder, it is best to use a 1-inch video tape recorder (in this case), since the 1-inch wide video cassette tape does not have a time code track, the audio track tube will be used instead. Furthermore, in this example, a 7-inch videotape was used for re-recording, but this can be changed to a video disc, and the time code recording tape can also be changed to magnetic tape, disc, 7El disc, etc. It is.

FIG. 1 is a block diagram showing an embodiment of the signal conversion processing section and output section of the present invention. This signal conversion processing section performs image quality improvement processing such as 9-time noise removal, edge enhancement, gradation correction, and scanning line interpolation in response to the above-mentioned re-recorded 91-inch wide videotape l and a desired side. In the present invention, the aforementioned videotape editing section and the color signal conversion processing section which performs image quality improvement processing have an off-in configuration. This offline configuration allows videotape editing and signal conversion processing to be performed independently.
It can be expected to improve work efficiency and utilize a more efficient system.

In Figure 1, first F! A 1-inch wide videotape with sickle images and a paper tape 12 on which time code information corresponding to a desired screen is recorded are set in a 1-inch helical scan type video tape recorder 1 and a paper tape reader 2, respectively. Next, by pressing the frame extraction switch located on the operation console BtlC, the information on the paper tape lλ is read into the frame search unit n for l frames, and the information is set in the 7-inch helical scan video tape recorder, 2/2, and 9 re-recorded. Playback of the 1-inch wide videotape begins. At the same time as playback starts, the time code information corresponding to each frame is sequentially read by the time code reader, and the frame search section n
is input to the paper tape reader 3 from the paper tape 12 first.
is read through and compared with the nine frame code.

When the information from the time code reader 22 and the information from the frame search unit n read from the paper tape 12 match,
A freeze command for the corresponding picture signal is output from the frame search section n to the noise reducer 1, and information for one desired screen is recorded in the built-in 7-frame memory by the noise reducer. At the same time, a playback stop signal is output from the 7-frame search section n to the I-inch helical scan video tape recorder l, and the tape recorder I
to stop. Note that until the information from the time code reader n and the information from the frame search unit read from the paper tape 12 are partially combined, the video tape playback stop signal is sent to the time base collector and noise reducer I.
The contents of the built-in frame memory are sequentially compared and noise components are removed. Also,
This content can be observed on the display monitor y. The time pace corrector b and the noise resolver I are part of the image quality improvement processing in the signal conversion processing section. The time pace corrector 1 is used to correct the temporal deviation of the video signal, which is usually called jitter, and when it is recorded in a single frame in the frame mode, it causes temporal jitter and starts sampling each scanning line. Prevent differences in the number of points and sample pixels. Noise Reducer-1 is used to improve image quality by suppressing various noises and emphasizing contours.
The quality of the image printed on the inch-wide videotape has deteriorated due to noise, etc. Noise may occur in the video editing department or in the signal conversion system during playback of the re-recorded videotape. The detail corrector 1 emphasizes changing points in the image and performs contour enhancement processing to make the image clear.

Next, the image quality improvement method according to the present invention described above will be explained using the drawings. FIG. 3 is a block diagram showing the configuration of the image quality modification section of the present invention. As mentioned above, the video signal is digitized by the MU/D converter asKXI, and the quality of the image is improved by the digital time pace corrector, noise reducer 1, and detail corrector X, and then the D/D converter is digitized. The digital signal is converted into an analog signal by the system converter 6 and output.

Examples thereof will be described below. The reference figure is a diagram showing the principle of an embodiment of the digital time base collector according to the present invention. The reproduced nine television signals are converted into digital signals by the MU/D converter S, and are transferred to the RAM j/D with the write/read switch jj set to the write side.
write to. The sampler frequency for A/N conversion is the one that separates the synchronization signal and color subcarrier signal from the synchronization and color subcarrier separator jJK, and is generated by the clock pulse generator S3, and is synchronized with the synchronization signal. The frequency is three times that of the color subcarrier signal. If this clock pulse is added to the write pulse generator input to generate a write pulse, writing to the specified address can be performed regardless of the presence or absence of jitter. Next, change the readout switch jj to the readout pulse generator S.
If the data recorded in the RAMIC is read by creating a read pulse similar to the write pulse from the synchronization signal of the video plate making unit and the color subcarrier via the sync signal 1, there will be no jitter at all, regardless of the presence or absence of jitter κ in the write K. It is possible to obtain a television signal that is synchronized with the synchronization signal of a video plate-making device that does not have a Also, this lightweight time pace corrector has a mildew that can easily compensate for K dropouts. Since that uses frame ▲ correlation 4, prepare a K frame memory separate from the RAMj/ in Figure D to record the data from l frame before, and when a dropout occurs, the 7 frame memory is used for that period only. It replaces the previous data stored in the frame memory. Other methods utilize the correlation between each pixel, and use appropriate interpolation methods based on the data of surrounding pixels of the pixel that has caused dropout. For example, methods that use the data of the previous scanning line as is, and Select either the method of taking the average value of the scanning line or the method of performing interpolation calculation from the data of a large number of pixels, and replace the resulting data with the obtained data. Figure 3 is a block diagram showing the configuration of a noise reducer that uses a digital recursive filter according to the present invention. The noise reducer has a very strong autocorrelation between frames in the television signal, but
We focused on the fact that the included noise components have almost no autocorrelation, and took advantage of the fact that when the average value is taken for each frame period, the energy of the video signal hardly changes K, whereas the energy of the noise component becomes low. This improves the ratio of 8/N. In Figure 3, the digital Eirin input signal ▲
is first supplied to the arithmetic circuit. In the arithmetic circuit 44, a coefficient κ(
1-K) ▲10KB calculation is performed and output. The output is stored in the frame memory 6l and used as κ data B when calculating the next frame. The chroma inverter ≦ is the ninth inverter that matches the phase when adding in the arithmetic circuit 66, since the chroma signal in the NTso system K has a K phase different from trσ for each frame ▲. by the way,
Noise Reducer K has a residual problem.

In the case of a still image or an image with little movement, the calculation circuit 4 is recursively added to the calculation circuit JjK from the input terminal.
4K is added to IJI, and since its shape and position on 7 rays are almost the same, the two overlap. On the other hand, in the case of fast-moving images, the position on the frame moves, resulting in displacement of the composite image and residual images. Therefore, for IIMK with little movement, K is increased to improve the S/N, and for IIMK with fast movement, the I OKL input signal is output as is.

This control is performed using a motion detector, which measures the difference between the input signal and the recursive signal and determines whether there is movement based on the magnitude of this difference. Since ▲ and 3 are almost the same for a painting with little movement, the difference is small K, and a large κ for a painting with fast movement, so this difference is added to the coefficient selection circuit κ and the size of X is ( There is a book in which K is set so that when ▲1B》 is small, it is a large K1, and when it is a large K, it is small κ.First, loose delay Go 7 has an arithmetic circuit of 46K added, and the time difference between ▲ and G is l7 rays. This is to adjust κ so that the circuit K in Fig. S.
The nine screen information selected in advance is stored in the frame memory.
/When writing to K, it is necessary to read the K screen 7 times.
At this time, the freeze signal is written to the read/write control circuit 43.
K is added and writing to frame memo IJ-K is stopped. At this time, the data recorded in the frame memory immediately before the freeze signal is applied is read out, and the desired still image quality can be obtained. A detail corrector I, which will be described later, is a circuit for emphasizing contours, and after emphasizing the contours of the painter, the video signal is converted into an analog signal K by a D/A converter 6K and output. FIG. 4 is a block diagram showing the configuration of the digital detail collector in the present invention K. Eirin input signals include luminance signal Y and chroma signal (3
This is composed of K, but this is a comb-shaped filter 7L.
Separate Y and a6c.

Various circuits are known for this comb-shaped filter, but we adopted the comb-shaped filter, which has good Y-0 separation characteristics. This Y
A detail signal in the horizontal scanning direction is obtained through a signal processing bandpass filter 72. The 0 signal passes through a low-pass filter 73 to obtain a detail signal in the vertical scanning direction, (1) detail signal, and (2) detail signal. These ■ and V detail signals are combined in the adder tail, and the plan-? Ng/
7.1t, the B/W clip 77, and the crispening circuit 74 make the necessary corrections, resulting in a completed +L9 detail signal, which is added to the original video signal by the adder 7Ir to create the outline. This results in an emphasized Eirin output signal. The pukunking/black level gate 7S is for erasing the detail signal near the black level where there is a lot of noise due to the pulse noise generated before and after the retrace period and the gun 1 capture. The crispening circuit F1 is a circuit that removes only low-level signals and can remove noise. B
In the /W clip 77, since the detail signal increases accordingly near the white and black levels of an image with strong contrast, resulting in an unnatural image, the size of the detail signal near the white and black levels is limited to create a natural - glK.

The large image signal that has completed this processing is sent to the R(jB, decoder MK in Figure 1) and is converted from the NTSO signal to the R()B signal. Similarly, since Y/C separation is performed using a comb-shaped filter, an image signal with excellent resolution and color tone can be obtained as described above.

A good signal separated into RGB signals can be detected as M4 on a KGB display monitor 35 via a gradation correction section 31. A corrector and a display 3λ are connected to the gradation correction unit 31, and manually perform contrast correction, parallel movement of gradation, gradation of light part or shadow part, etc. for each RGB signal. Adjustment is possible, and the correction results are displayed on the RGB display monitor 35 at any time. Note that the static IdI1gI signal frozen in the noise reducer is
Since display monitor J9 is also displayed in the state before gradation correction, gradation corrections can be made as necessary while comparing with the RGB display monitor p-is which is displaying the result of gradation correction. . In addition, when a cursor signal is inserted into the correction device and display 32, the video level at any point of the still image displayed on the RG1 display monitor B can be changed to the video level. The comparison value with respect to the signal standard value a7VK can be numerically displayed on the corrector and the display unit. moreover,
Must! When the gradation is corrected for each No. 18111 in accordance with the above, the setting position information of the corrector and the gradation correction knob of the display 32 can be printed out to the printer 3j. 1. When using the RSG and IS outputs of the RGB camera 2 without using a videotape, it is possible to directly input the outputs to the gradation correction section J/K. Must! When the correction is completed, the R%G, 1 still image signal, which has been corrected according to , is converted to l scanning line 7 ≦! in real time via Mu/D conversion 5lJ4 by pressing the BO correction completion instruction switch on the operator console. Pixel O is converted to digital information, R, GSB
The 7-ray, 5-metre mark corresponding to each signal is recorded in 77, and the recording of RG11 on the 111/- side is completed. If the R%01B video information has been digitized in advance, it is possible to use that digital data to input directly into the 7th frame to 4th frame frame.Next, frame The R, G, B□ corrected still image information recorded in the memory ?7 is transferred to the scanning line interpolation unit I corresponding to each signal by 7247 minutes.In addition, in the frame memory r, even field and Odd field information is stored in separate addresses and transferred to the rounding and scanning line interpolation unit y, which constitutes 17 still image frames.
The signals for the scanning lines are read out alternately in the order of the odd and even field scanning lines in ascending order of numbers. Here, the scanning method is switched from the interlaced method to the sequential method, and by this switching, it is possible to overcome the drawbacks of the interlaced method and prevent the image quality from deteriorating. The number of scanning line signals transferred to the scanning line interpolation unit I is equal to the number of television scanning lines!
Ko! After subtracting the number of scanning lines corresponding to the blanking period, this is the signal for the reference signal. The scanning line interpolation unit ff performs interpolation calculations to increase the number of scanning lines from tti to approximately tti times /? Increase the number of lines to a reference copy, and then press K so that the scanning lines 0/part overlap during exposure so that they do not have difficulty recognizing each line as a separate line. 9. The interpolation effect can also increase the solving power. In the interpolation calculation in the present invention, the point at which a new pixel is to be set, that is, the interpolation point, is determined by considering the contribution rate of surrounding pixels. The method is configured such that the nearest key bar method, the pi-linear method, and the cubic composite silane method can be selected by switching the switch. The nearest key bar method uses the data of adjacent pixels as the pixel data of its 11 interpolation points, and is suitable for images converted to λ values.
The pi + 7 niya method determines the pixel data at the interpolation point assuming that the data between scanning lines changes linearly, and the image Km with many halftones is used. This method determines the pixel data at the interpolation point from the correlation of the data, and is suitable for any i1i. This interpolation calculation requires 71 multiplications and additions per interpolation pixel for about izo million pixels per li# surface, so the calculation speed is slow and time-consuming with the convenience computer's no-toware processing. It's too bulky. In the present invention, the scanning line interpolation section X is configured with a hardware element, and data is output to the output section of the next stage in real time, thereby making it possible to produce a film extremely quickly.

The image information subjected to scanning line interpolation calculations for R and GSB at the same time by the scanning line interpolation unit 31 of the signal conversion processing unit is supplied to the output unit,
It is output to either color film or film wrapped around the exposure section of a color scanner, or both. Furthermore, the present invention enables more advanced prepress output and automation through an interface with a layout scanner system that outputs with an editing function. When outputting to color film, the scanning line interpolation calculation is performed by the scanning line interpolation unit n, and the nine-stroke information is sent to the high-resolution cathode ray tube of the color film production device V via the color film production device interface n, and RlG, B Each color is sequentially displayed as a black and white image with visible light wavelength energy. A color film is placed in front of the high-resolution cathode ray tube through a filter that supports black and white images with R, G, and B information. Each filter is switched in synchronization with each black and white image signal and is sequentially exposed onto the color film. Once the exposure is complete, the color film is automatically unframed to enable exposure of the next selected picture. In addition, for color film, the standard image size of ≦X7cm+ size is J/x41mg, which is about 1 times larger in area ratio than the image size obtained with the conventional color CRT photography method. We will discuss the case of outputting film from a zero-order color scanner, which has extremely high image quality. The image information interpolated by the scanning line interpolator 3g is sent to the color scanner interface f.
/ is transferred by a clock signal synchronized with the rotational speed of the color scanner Q. Transfer information is transferred as an analog signal to the Color Cobieter of Color Scanner 2 *R%
After the G%B signal signal width part is input, the color printing color Y, M%cSBIC is processed through the signal processing system of the color scanner.
Y is converted into a signal and displayed on the film as a percentage in the exposed area.

In the present invention, it is also possible to supply the output of the color scanner p to the layout scanner system UK and provide an editing function.

FIG. 7 is a block diagram showing the configuration of an embodiment of the layout scanner system Q. The layout scanner system will be explained below with reference to FIG. The input device 1/ picks up information from a color document, text document, etc. using a scanning method, and the present invention uses the color scanner method shown in FIG. The supplied analog image information is converted into digital data by a MU/D converter, and is temporarily stored in an external storage device via a digital converter. Regarding the external storage device, the 0-picture environment editing device t3, which uses one or more magnetic disk devices with a large storage capacity (approximately 200 megabytes), is equipped with a keyboard, digitizer, and monitor display. These are used to input the page layout information of the copy mount.This page layout information is also stored on the magnetic disk described above or on another magnetic disk device via the digital computer NVT. When performing page make-up, enter a command from the keyboard of the ImgIA processing/editing device 130 to call up page layout information on the display, and then enter a command from the 1-keyboard to call up the image information from the magnetic disk and specify it. 0 Next, when inputting the command regarding the mask, )IJ? Artist information other than the image size is deleted from the image purchase, leaving only the necessary image information. If you are dissatisfied with the tone, retouching is also possible with correction instructions. In addition to moving, masking, and correcting the above-mentioned patterns, the commands necessary for page make-up include cropping, overlapping patterns, flat netting, and tsunafuse. When the page make-up processing as instructed by the operator is completed, the O2 image information is stored in a predetermined magnetic disk device via the digital combiator n. The information after the ζO page makeup process is obtained by converting it into a film from the output device 8 when necessary.

As is clear from the above details, the present invention is more effective than the conventional method of displaying continuous video footage on a color cathode ray tube, selecting the desired screen, and then photographing it with a still camera. , screen selection and extraction can be performed extremely accurately. In addition, the time pace corrector corrects the temporal deviation of the video signal, the noise reducer suppresses the noise signal included in the video signal, the detail corrector emphasizes the outline of the image, and the R
Implemented various image quality improvement measures, such as correcting GB signal gradation, converting the scanning method, increasing the number of scanning lines through two-dimensional interpolation processing, eliminating scanning lines, and increasing resolution. After that, the separation plates are obtained from a color scanner for color film and/or color film, so the problems of TMS quality such as color tone, resolution, television scanning helix, etc., which are encountered in conventional methods, can be completely solved. Furthermore, since the videotape editing section and the signal conversion processing section that performs image quality improvement processing employ an offline configuration, each work can be done independently, allowing for highly efficient operation. Furthermore, in the output section, Neuau F
At O, which has introduced a scanner system, the main tasks in the plate-making process, such as photo processing, composition preparation such as master creation, and manual departments with many labor-intensive elements such as composition, can now be automatically processed. We can be friends.
