Abstract

PURPOSE:To attain a uniform control in case the regions of different indications of image resolving power or the scan end covers the boundary between regions during a main scan and without having a special switch control of scanning lines, by providing a small quantity of hardware to an output controller. CONSTITUTION:An output controller 2 is provided to a paper surface output control system, and a host computer 1 is connected to an interface part 3 of the controller 2. At the same time, a control computer 10 is provided to the controller 2 to perform the editing processing. Then the working indication data designating the attributes including the data indication, and address containing image resolution, etc. is stored in a buffer memory 4. Furthermore a master which converts the character part of an article indicated by said indication data into picture elements is stored in a character generator 5, and image memory 6 stores a master which converts the picture part of the article into picture elements. Then a work memory 7, an image buffer 8 and an interface part 9 are used to ensure a uniform control with no switching control of scanning lines nor switching of processings.

Description

[Detailed Description of the Invention] (A) Field The present invention is a computer-controlled nail surface creation system using automatic typesetting (so-called CTS), in particular, by changing the resolution between the text section and the insertion section. Layer surface of CTS block + L1 card to create paper surface? j Control method (b)
Conventional technology and background In place of silk printing, where the type was picked up by hand, in recent years computers have been used to paste the paper, converting the characters or η negative data that fill the area of the pasted paper into pixel images, and converting them into pixel images. CTS, which creates the actual page by scanning the pixelated image data with a plotter and outputting it to the page master, has been put into practical use, and is particularly popular in newspaper and breaking news publishing due to its speedy processing and labor-saving properties. This is starting to become popular, although depending on the cost of the system it may cost a general publication one.

However, if you consider the space of these publications, there is a part for the article and a part for illustrations or photographs, or a part for adverts with pictures and wide photographs. The resolving power (pixel density) required to depict text and the resolving power required for depicting photographs are generally more demanding for photographs, for example, in newspapers such as 0CTS, article parts are 454 dots/inch (commonly known as 454 pitch), photos and public notices are 681
The paper is created with different pixel densities (referred to as 681 pitch) as the standard, but the paper is created with different pixel densities. Divide the corresponding virtual paper into areas and divide the inside of each area into two areas filled with pixel conversion areas (J). Instead of creating the actual page by scanning in two steps with a block that can be scanned at a pixel pitch of The work of converting and creating a virtual paper surface and the professional blank scanning are performed twice (this takes time).

In addition, the latter has the disadvantage that the capacity of the memory for recording the paper as image data is large, and the amount of calculation required for processing is also large, making it necessary to increase the capacity of the device (and taking time).

(c) Objectives and Features The purpose of the present invention is to solve these drawbacks and to improve the scanning density of the plotter during scanning by changing the scanning density of the plotter across the main and secondary surface directions and the running bundle of the blocks and the ivy. Scanning output control t that supplies a scanning take with a mixed scanning pitch of
Thus, the solution is “to aim at.

The feature of the present invention is that the computer t
This paper space (this corresponds to the address attached to the paper space - this area is specified by processing the space creation instruction data that has the assigned address, resolution instruction, content specification, or content data). Pixel image creation for block output of an automatic typesetting system that converts pixel sections divided into pixel dimensions into pixel images, and sends the pixel images in blocks in the scanning order of a plotter to create a paper surface. The number of bits in the main scanning direction for the minimum number of bonds in the number of valley divisions when dividing, and the minimum number of bonds in the number of valley divisions at the scanning end of n blocks prepared so as to form the same sub-scanning width. It has a memory having a sub-scanning bit number of 1, and the basic image data on the working memory is converted into 1 basic pixels for each area, and the pixel size 1 can be scanned and scanned according to the resolution instructions for each area. The image data is enlarged in both the main and sub-scan directions at the corresponding enlargement ratios, edited and arranged in the order of the main scan according to the number of scans at the scanning end, and then the image data is It is to supply the write head to the scanning end of the block that shares the sub-scanning width.

Figure 2 is an explanatory diagram of the paper surface and the image area where the address is developed. In the figure, [P] is the page surface or the pixel corresponding to the paper surface. This is the 454 pitch that is mainly used here, so the address is developed.

Create image data. If the area is 11 times larger, it is possible to divide it at an appropriate sub-scanning address even if the attributes on the sub-scanning side do not change.

Based on the fact that the regions of β, r, and δ following α are also Yb) Yb-1 and Y a (Y b, and β and γ
The area between and δ is selected as an area for pixel transformation T by determining the j order in the main running f order, and for β and δ, image data of 454 pitches like αt+= is used, and for γ, from attribute B. Create 681 pitch image data. Next, the image data prepared in this way is transferred to the image buffer 8 for matching with the paper surface scanning of the block to be scanned with a bundle of the scanning ends of the Kirikawa Shishi block for the main scanning 4541 and sub-scanning of the block. As shown in Figure 3 created above (the image buffer 8 has 6900 pixels in 454 pixels, which fills the width from the main scanning address Xo to Xz that make up the paper surface, and the number of pixels in 681 pixels is 10350).

00 bits, sub-scanning direction l The number of sub-scanning lines at the main scanning edge of the moss metal is 2 lines at 454 pitches and 3 lines at 681 pitches.
Considering example 1 of the configuration of H during scanning, the minimum required number is 1 to 2070 in the X direction with a width of 2×3, that is, 6 bits.
0 in the Y direction (n This is the address in the basic art system that defines the area.

Then, to create image data in the image buffer for output matching prepared in this way, the image data that had been previously created for each selected area on the working memory 7 is used for both the main and sub-directions for attribute A. While enlarging this 3 times (this), enlarge each attribute B by 2 times, compare the main and secondary addresses, and give priority to the one with the younger address. (This creates the image data for the scans developed into basic pixels, so all that is left is to scan the basic pixels at the scanning end of the plotter that corresponds to the paper surface to create the paper surface.) Ru.

(E) Effect With this method, since the block gA11 is scanned by basic pixels, the scanning edge can be changed during main scanning without any particular control to switch the scanning edge, even when scanning an area with a different resolution instruction. Even when it is necessary to scan across area boundaries, it can be uniformly controlled without changing processing or scanning control, and the capacity of the image buffer is increased as a 71-code for creating output image data. At the scanning end of a block divided into n and basic pixels, it has the characteristic effect that the output page can be created extremely efficiently by simply increasing the number of steps for enlarging the image-converted pixels as arithmetic processing. be.
