Abstract

PURPOSE:To perfectly execute an accurate trimming designating operation and to confirm the trimming of a pattern in a state where preprocessing is under a light load by superimposing layout position information and line drawing information on an identical screen by using a screen display means and superimposing and displaying pattern information on the screen. CONSTITUTION:A trimming specification frame is inputted from a block copy 5 by a digitizer 4 and displayed on a monitor display 8. The contour, etc., of the pattern is image-inputted from a layout specification paper 11 as a working line, which is digitized and becomes a line drawing. The line drawing is superimposed and displayed on the trimming specification frame and they are allowed to agree with each other. Then, digital data(pattern) is inputted from a photographic original 2 by a scanner 1, etc., and superimposed and displayed on the trimming specification frame/line drawing, and the trimming position of the digital data is decided. Thus, the accurate trimming designating operation is perfectly executed and the trimming of the pattern is confirmed in the state where the preprocessing is under the light load.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pattern trimming position alignment method in, for example, a layout scanner system, in which a binary image of a pattern photographed by a camera is used as a strike line during trimming position alignment. This simplifies the trimming and positioning of patterns.

<Conventional technology> In recent years, with the development of printing plate-making methods and design methods,
Layout scanner systems have been proposed that use computers to perform image cropping and layout.

This layout scanner system includes a means for inputting image data such as a digitizer, scanner, or camera, a CPU for processing the input data such as calculations, a storage means for storing the input data and/or processed data, and a screen for displaying the processed data. and output means for outputting a display or the like.

Hereinafter, a positioning method for pattern trimming using such a conventional layout scanner system will be described.

For example, using a photo original 61 as shown in FIG.
Consider the case where layout images 71 and 72 as shown in the figure are created.

The photographic original (picture) shown in FIG. 6 is input into a computer as digital data by an image input device such as a camera or a scanner. Or stored in an external storage device such as a magnetic disk.

This imported digital data is displayed on a monitor display to perform trimming and layout work.

At that time, trim (place) the above digital data (picture) at which position on the layout paper (CRT screen).
The criteria for deciding whether to do so or not is based on the mask, format, etc. created during the planning stage.

Conventionally, an operator displays a trimming designation frame as a line drawing on a monitor display, and superimposes corresponding digital data (picture) within the trimming designation frame as a gradation image.

Thereafter, this gradation image (picture) is moved up and down, left and right, rotated, and scaled, and then stopped at a designated position for appropriate trimming.

In this case, the appropriate trimming position is based on the above-mentioned block mount, appearance, etc., and is determined by the 8th
The figure 81 shown in the figure is specified by inputting it into a computer as a line drawing using a digitizer. For example, if this figure 81 is superimposed and displayed as a line drawing on a monitor display, stopped at an appropriate trimming position, and then subjected to layout processing (synthesis) by a computer, the layout image shown in FIG. 7 is created. .

In this case, the figure 81 is created by placing the layout designation paper on top of the layout designation paper in the correct register when placing the layout design on the digitizer table and inputting the position information. It is obtained by tracing the outline with a pen digitizer or the like.

<Problems to be Solved by the Invention> However, such conventional methods have the following drawbacks.

First, using a digitizer or the like to input graphic information such as the mount, format, etc. into a computer as a line drawing requires a heavy preprocessing load.

Second, especially when trying to input complex line drawings as a guide for trimming more accurately, it depends on the input accuracy of each worker, and it is even more difficult due to the large amount of input information for one line drawing. The burden will increase.

Thirdly, the line drawing input above is a guideline for trimming,
Even if cropping is determined on the monitor display accordingly, it will not be completely accurate.

Fourthly, if the layout is inputted using a pen digitizer or the like by overlapping the designated paper with a base board, there is a risk that these papers may be misaligned during input.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method that allows completely accurate trimming instruction work and allows for confirmation of pattern trimming with a low preprocessing load.

Means for Solving the Problems> The present invention uses a scanner system equipped with an input means for information such as images, a control processing means for the input information, a storage means for these information, and a screen display means for the information. In the pattern trimming alignment method of trimming the pattern of a photographic original based on the printing plate and layout specification paper, a printing plate for printing or design is used, and a certain layout position of the pattern is set corresponding to this printing plate. Prepare the layout designation paper and the photo manuscript on which this picture is recorded, input the layout position information from this block copy using the input means, and input the design to be laid out from the layout designation paper using the input means. The outline of the picture inputted by the image input device is extracted and stored in the storage means as line drawing information, the picture information is inputted from the photographic manuscript by the input means, and these Layout position information and line drawing information are superimposed on the same screen using the screen display means, and the pattern information is superimposed and displayed on this superimposed screen, so that the pattern information matches the line drawing information, and This is a pattern trimming and positioning method in which layout position information and pattern information are subjected to layout processing by the control processing means.

Further, the present invention provides the above layout position information, line drawing information,
The trimming position of a picture according to the first claim, wherein when picture information is displayed in a superimposed manner on the same screen, a positional shift on the screen is corrected by performing coordinate transformation on any of these pieces of information. This is a matching method.

Furthermore, when the layout position information, line drawing information, and pattern information are displayed in a superimposed manner on the same screen, the trimming positioning of the pattern according to the first claim, wherein the display color of the line drawing information on the screen is changed. It's a method.

Effects> In the present invention, a trimming designation frame (position information or mask information) is input from the master using a digitizer. This trimming designation frame is then displayed on the monitor display.

Then, the outline of the picture, etc., is inputted as an outline line from the layout (designated layout sheet). The Atari line is binarized and becomes a line drawing.

This line drawing is displayed superimposed on the trimming designation frame, and these are further made to match.

Further, digital data (pictures) are input from the photographic manuscript using a scanner or the like. Then, this digital data is further superimposed on the trimming designation frame/line drawing and displayed. For example, this digital data is scrolled to determine the trimming position of the digital data.

Thereafter, the digital data of the picture is combined with position information and line drawing information and subjected to layout processing.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the device configuration of a layout scanner system for implementing the method of the present invention. .

In this figure, reference numeral 1 denotes an image input device, such as a scanning section of an image scanner. Further, reference numeral 2 denotes a photographic original read by this image input device 1.

The digital data a indicating the picture taken from the photo original 2 is given to the CPU 3 as a central processing and control device using a computer.

This CPU 3 can store the digital data a in a storage device 7 such as a hard disk.

Further, in addition to the digital data a from the image input device 1, the CPU 3 is given coordinate position data b based on the block mount 5 from a layout figure input device 4 such as a digitizer, and further, The configuration is such that instructions (commands) by an operator are input from an input device 6 such as a keyboard or a mouse.

Further, the CPU 3 is configured to input the layout and trimming specification paper arranged on the camera stand 9, for example, the format 11, as an atari nc by the camera 10.

8 is a monitor display (CRT), and this CR
The content (picture) of the digital data a stored in the storage device 7 is given to T8 by the CPU 3 and displayed.

12 is an image output device which is an exposure section of an image scanner, and 13 is a film on which an image is formed in this image output device 12.

FIG. 2 is a flowchart showing the method of the present invention executed by this CPU 3.

First, the mask data for the block is coordinate position data b (image layout position or mask information) based on the block base 5 from the layout figure input device 4 such as a digitizer.
(step Sl). This mask data (coordinate position data b) is stored in the storage device 7 and displayed on the CRT 8 (S2).

Next, a layout and trimming designation paper, for example, a format 11 indicating a designated trimming position, is inputted as a hit line C by the camera 10 (S3).

The gradation image imported as this Atari line C is binarized to form the outline of the picture, and this Atari line C is also
is displayed (S4).

Then, this format (atari line C) is moved under the control of the CPU 3 and superimposed on the block copy (coordinate position data b) (S5).

Next, a picture (digital data a) is input from the photographic original 2 using the image input device 1, and is stored in the storage device 7 (
S6). Then, for example, this color-separated picture is displayed on the monitor 8 (S7).

Therefore, for the digital data a stored in the storage device 7, a trimming range is specified based on the coordinate position data b, and the above-mentioned attrition line C input by the camera 10 for this range of digital data a is specified. The images are displayed on the CRT 8 in a superimposed manner. Furthermore, the digital data a for this hit line C is also displayed on the CRT 8.

Then, the CPU 3 moves the digital data a vertically, horizontally, etc., rotates it, and changes the magnification so that the digital data a coincides with the digital data a on the CRTB (S8).

If the above-mentioned hit line C and the digital data a match on the screen of the CRT 8, a layout process is performed by the CPU 3 based on the above-mentioned coordinate position data b (S9
).

The laid out data d created by this process is
The image is stored in the storage device 7, and then outputted to the image output device 12 and formed as an image on the film 13.

FIG. 3 is a state transition diagram showing a CRT screen according to an embodiment of the present invention, and this will be explained with reference to the device configuration of FIG. 1.

At the time of trimming position alignment, first, a trimming designation frame 21 is displayed on the monitor screen 20 (FIG. 3 1).

Next, the gradation image from the camera 10 is the Atari line C.
The image data is taken into the CPU 3 as an image and displayed in a superimposed manner on the monitor screen 20 by an operator's operation.

At this time, this hit line C is converted into a binary image with an arbitrary darkness value, and becomes a hit designation frame 22 and a binary hit line 23 (■ in the figure).

The operator zooms up, zooms down, translates, and rotates the camera 10 to display the trimming frame 21 and the hit designation frame 22 on the monitor screen 20 so that they overlap in the same size (■ in the figure). .

After performing the above operations, the operator
4 is further superimposed on this monitor screen 20 (see
), the digital data 24 is moved vertically, horizontally, etc., rotated, and magnified to match the binary hit line 23, and the trimming positioning work is completed (■ in the figure).

Note that if the format 11 is installed on the -degree camera stand 9, even if there is a plurality of digital data that should not be trimmed and positioned, the operator need only repeat the above series of operations.

Further, FIG. 4 is a diagram for explaining a case where it is necessary to make corrections on the display screen in the above-mentioned trimming work.

As shown in this figure, compared to the graphic information, the trimming designation paper 11 is created by copying or the like, so the graphics are often distorted. In such a case, the coordinates of the first indicated point (2) are transformed using the fixed point 0 as a reference. For the second pointing point ■ to the third pointing point ■, this O and ■
A predetermined coordinate transformation is performed using as a fixed axis. In this manner, coordinate transformation is subsequently performed for all pixels to correct distortion of the figure.

FIG. 5 is a diagram for explaining an example of correction upon screen display.

In normal color display when specifying trimming, if the color is high in density, the hit frame (hit line C) is a single color, making it difficult for the operator to visually recognize it.

For this reason, it may be difficult to specify trimming on the screen.

Therefore, in this embodiment, complementary colors are corrected for the values of pixels displayed in color using a look-up table. The Atari line C is displayed as a complementary color to the background image.

In addition, pixels for color display (having 256 gradations) can also be displayed with gradations in half of the area. In other words, values from 0 to 255 are compressed to values from 0 to 127, and even dark areas are displayed brightly with intermediate gradations. At this time, displaying the hit line C in black makes the screen much easier to see.

Furthermore, by changing the color of the cursor, the screen display can be made easier to see. For example, there are normally four colors, but these are changed depending on the color tone of the background pattern.

<Effects> As described above, according to the present invention, it is possible to perform a completely accurate trimming instruction work, and to check the trimming of a pattern with a low preprocessing load. Further, more accurate trimming positioning can be performed by distortion correction. Furthermore, by changing the color display of the fill lines, etc., this trimming work becomes extremely easy.
