Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image data layout processing method for trimming and laying out image data to form print image data.

[Conventional technology]

In recent years, layout systems that use computers to perform layout work for printing plate making have become commonplace, and in this system, image data read using a scanner is stored in memory, which is then read out and used for various processing. That's what I do.

In this case, page allocation may be performed by laying out a plurality of identical pictures as printing image data with respect to trimming figures of the same shape or different shapes.

Conventionally, this type of layout has employed a method of allocating image data for each trimming figure, and the work involved is as follows.

In other words, only the necessary area of the document surface is trimmed,
This is a method of specifying where on the image plane of one page the image is to be allocated. First, the image data imported into the memory is taken out and displayed on the display, and at the same time, the cursor image indicating the trimming range and the image data of the document are arbitrarily moved on the display screen and placed at the position specified on the layout sheet. The method used is to sequentially insert the images from the original manuscript.

[Problem that the invention seeks to solve]

As mentioned above, it has been pointed out that the work of allocating image data for each trimming figure requires a large amount of operations and is extremely inefficient.

The present invention has been made in consideration of the above points, and
It is an object of the present invention to provide an image data layout method that does not require layout work for each trimming figure.

[Means for solving problems]

In order to achieve the above object, the present invention captures image data to be laid out from a manuscript, captures layout position data of a plurality of trimming figures defined on a layout mount, and stores the image data and the first trimming figure among the trimming figures. displaying a trimming figure on a display, and performing layout by moving the first trimming figure with respect to the displayed image data so that a specific point of the image coincides with a predetermined point of the image data; Next, by matching the corresponding point of the second trimming figure in the trimming figure with the reference point of the first trimming figure, the second trimming figure is adjusted based on the first trimming figure.
A first image data layout method, in which the image data is trimmed using a trimming figure, and thereby a plurality of image data that has been trimmed for each of a plurality of trimming figures is extracted using the image data, and this method In the above, an image data layout processing method uses three or more of the trimming figures, and the image data is sequentially layout-processed for each of the plurality of trimming figures; displaying the layout position data of a plurality of trimming figures defined in , the image data, and a first trimming figure among the trimming figures on a display, and assigning the first trimming figure to the displayed image. Then, based on the allocation position data, a positional deviation of the second trimming figure among the trimming figures with respect to the first trimming figure is determined, and based on this positional deviation, the first trimming figure is
a second image data layout processing method, wherein the image data is trimmed by the trimming figure and the second trimming figure, and thereby the trimmed image data of the image data is extracted; Alternatively, in each of the second methods, position data of a specific point with respect to a first trimming figure among the trimming figures is taken in, and the specific point of the image data displayed on the display is set as the position data of a specific point with respect to the first trimming figure. The present invention provides a layout method for image data, which layouts image data so as to match position data.

[Effect]

Layout position data of a plurality of trimming figures and specific point data of the image data are imported. On the other hand, the image data captured from the original is read out and displayed on the display. One of the plurality of trimming figures is displayed on the display superimposed on this image data. Then, the first layout is performed by moving this trimming figure relative to the image data so that the specific point has a specific positional relationship with the image data, and then the first trimming is performed in alignment with this image data. The other trimming figure is superimposed on the figure to determine the relative positional relationship between the two trimming figures, the positional relationship of the other trimming figure with respect to the image data is obtained, and the layout of the other trimming figure is performed. If there are more trimming figures, the operations for the other trimming figures are repeated for each of these trimming figures.

In addition, when laying out image data in a form that combines multiple trimming shapes, first perform a partial layout of the image data for the first trimming shape, then align the other trimming shapes with respect to the first trimming shape. After that, the remaining part of the image data for the first trimmed figure is laid out.

〔Effect of the invention〕

As described above, when allocating the same image data to multiple trimming figures, if the image data is laid out for the first trimming figure, then the other trimming figures are laid out using the first trimming figure or already laid out. Since the layout of the image data for the other trimming figures is performed by determining the positional relationship with respect to the first trimming figure, the layout can be performed using the layout contents of the image data for the first trimming figure. As a result, when trimming a large number of the same image, once one trimming figure has been trimmed, other trimming figures can be easily trimmed by simply specifying the trimming figure.

Furthermore, when combining multiple trimming figures to form a single trimming figure, the positional relationships between the trimming figures are determined accurately and they are combined, so discontinuities in image data occur when the positional relationships are inaccurate. This prevents distortion and creates a layout with natural connections throughout the image.

〔Example〕

FIG. 1 shows the flow of operations for layout processing in one embodiment of the present invention, and the contents of this operation will be explained below in conjunction with the situation explanatory diagrams shown in FIGS. 2 a to f. . FIG. 3 shows the operation contents for another layout process of the present invention. Figures 4a to 7g explain how to find the center points of various trimming figures used in layout, and Figures 5 to 7
The figure illustrates the configuration of an apparatus used to carry out the present invention.

First, the configuration of the apparatus will be explained with reference to FIGS. 5 to 7.

FIG. 5 shows the configuration of an apparatus used to carry out the method of the present invention. Reference numeral 1 indicates a drum of a layout scanner, which consists of a scanning drum 1A and an exposure drum 1B. The exposure drum 1B is used for film exposure and is used for exposure after image data processing according to the method of the present invention, so its explanation will be omitted.

The scanning drum 1A has an original 2 affixed to its circumferential surface, and the scan range and magnification ratio are specified to take out the image data of the original 2 and write it into the memory 8 via the control device 3. The operation is controlled by a control device 3.

The control device 3 processes image data in response to layout data input from the data tablet 4 or the keyboard 7, and in addition to writing data to the memory 8 mentioned above, outputs data to the display 6, trimming, and layout. It performs calculations such as these and outputs data to the exposure drum 1B.

The data tablet 4 and the keyboard 7 for inputting data to the control device 3 are used for the same purpose, and in the case of the data tablet 4, the cursor 4A is used to input allocation position data and Specific point position data is input, and magnification change data is input using menu area 4B.
In the case of the keyboard 7, each of the above data is measured or determined in advance, and the numerical values are entered.

This data tablet 4 or keyboard 7
In response to input data from the scanning drum 1A, the control device 3 takes in the image data of the document 2 from the scanning drum 1A, stores it in the memory 8, outputs the image data in the memory 8 to the display 6, and outputs the image data of the exposure drum 1B.

Input is also made by pointing the specific point P _a (x _a , y _a ) on the image with the cursor 4A. As a result, the trimming range K based on the origin O and the specific point P _a of the image are input. If the trimming range is not rectangular but circular, input the center point and the circumference.
This is done by inputting points and, in the case of polygons, each vertex.

is written into the memory 8 by.

Next, the content of layout processing in the present invention will be explained with reference to FIG. 1 and FIG. 2. The situation accompanying the operation contents shown in FIG. 1 is as shown in FIG. 2. In other words, assume that there is a layout board as shown in FIG. 2a. On this layout board, a circle is shown as figure A, and a square is shown as figure B. It is assumed that image data previously stored in memory is allocated to these two figures. For this reason, as shown in FIG. 2b, image data of a person is displayed on the display 6, and a figure A, that is, a circle, is displayed superimposed thereon. The position of the figure A relative to the image can be changed by operating the cursor 4A of the data tablet 4. Therefore, a specific point set in advance on the image can be aligned with, for example, the center of the figure A. And as shown in Figure 2c,
Circle A with image data 10 laid out
Let Δx1 and Δy1 be coordinate shifts between the lower left vertex 12 of the square 13 circumscribing the square 13 and the lower left vertex 11 of the image data 10. Next, as shown in FIG. 2d, graphic B is superimposed on graphic A, and the layout result for graphic A is used for graphic B to perform layout. Since figures A and B are both point-symmetric figures, they can be accurately superimposed using the center point.
Center point of figure B [(x21+x22)/2, (x21+
x22)/2] can be accurately determined from the upper right vertex (x22, y22) and lower left vertex (x21, y21) of figure B.
When figure A and figure B are accurately superimposed, the lower left vertex 12 of square 13 circumscribing circle A
The deviation between and the lower left vertex 14 of figure B is shown in Figure 2 e.
As shown in , the lower left vertex 14 of figure B and the lower left vertex 11 of image data 10 are Δx2=Δx−1−X,
It is determined as Δy2=Δy1−Y. If the image data 10 is laid out with this figure B, the image data can be laid out in the same way as with the figure A. FIG. 2f shows the image data after layout obtained as a result, and shows the state stored in the memory.

FIG. 1 shows this in the form of a flowchart. The difference in Fig. 1 from the above is that position data such as the trimming range is imported before image data is imported, but this difference is not particularly superior to the other, but is simply a matter of Only before and after the procedure.

According to this flowchart, the first step is
In S1, the position data of the trimming range of the layout mount and the position data of the specific point are input on the tablet. Next, in step S2, the magnification ratio of the scanner is input. Inputs in steps S1 and S2 may be performed using a keyboard or the like. This position data and magnification data must be entered for each document, and if there are multiple documents to be input, enter them for all of them (step
S3).

When you have finished inputting all manuscripts, click Step
Paste the original onto the scanner's scanning drum using S4,
Read image data and store in memory. This is also done for multiple manuscripts as necessary (S5).

Next, in step S6, an image to be laid out is selected from among the plurality of images already stored in the memory, and in step S7, the instructed image data is displayed on the display. Next, position data of a specific point in the displayed image is input on the display (step S8), and further, in step S9, the position of the image, that is, the relative position between the image and the trimming figure is determined.

When the positions of the image data and the trimming figure have been determined in this way, in step S10, the apex of the first trimming figure (figure A), more precisely, the apex 12 of the circumscribed rectangle of figure A, and the vertex 11 of the image data 10 are The distance, that is, the coordinate shift between the two Δx1,
Calculate Δy1 (Figure 2c). Also step S11
The center point of each trimming figure selected by is calculated.

Thereafter, in step S12, the center points of the trimmed figure A and the untrimmed figure B are made to coincide with each other, and the relative distances X and Y of the vertices of the circumscribed rectangle are determined (FIG. 2d). Next, in step S13, the distances Δx2, Δy2 (Fig. 2 e) with respect to the image data of figure B are determined.
seek. When this operation is completed for all the trimming figures (step S14), the process moves to the layout processing from step S15 onwards.

In step S15, a trimming layout calculation is performed on each image data according to the position data of each trimming range. Then, in step S16, the layout status is displayed on the display for the worker to confirm. After this, check if there are any changes and if there are any, please proceed to the steps below.
After changing and correcting the layout information in S18, steps S15 to S17 are repeated.

3a to 3d illustrate another trimming method of the present invention. That is, this is an example of a trimming figure in which a rectangle as figure C and a circle as figure D partially overlap. In this case, the above-mentioned method is used up to the middle. For example, the above layout is performed for figure C, and the positional deviation Δx3, Δy3 of the trimming figure with respect to the image data (Fig. 3b)
seek. Next, as shown in Fig. 3c, the positional deviations X and Y between the trimming figures are determined, and with reference to this deviation, the same image data for figure D as figure C, that is, figure C and figure D are integrally obtained. Layout the image as follows.

In this case, the positional deviation between the trimming figures is accurately determined, and the layout is performed based on this deviation, so that one image can be accurately positioned and laid out with respect to the two trimming figures. Therefore, the laid out image does not look unnatural.

FIGS. 4a to 4g show how to find the center point of various trimming figures. Figure a is a rectangle, Figure b is a circle as described above, Figure c is an ellipse, Figure d is an ellipse including an anti-ellipse, Figure e is a polygon whose representative example is a hexagon, Figure f is fan-shaped, Figure g
indicates rounded corners, and the center point of each is determined using the calculation formula in the figure.

In this example, the image data is laid out using the center point as the reference point of the trimming figure, but in addition to this center point, the center point or circumcenter point found from the shape of the trimming figure can also be used. You can also do the layout using
