Abstract

PURPOSE:To omit the trouble of joint of copies by dividing a picture data into plural grating blocks, using them as a unit and applying data conversion so as to attain a prescribed number of multiple and reading sequentially data of adjacent grating blocks in column and row directions. CONSTITUTION:A picture data is stored in a display file section 1 while being divided into plural grating clocks. A position/magnification calculating routine section 2 calculates the data of the specific grating block so as to be a prescribed number of multiple and the data is written sequentially to a bit map section 3 having a memory of a bit number corresponding to the picture element number constituting a screen of a CRT 5. The position/magnification calculating routine section 2 reads data of adjacent grating blocks sequentially in the column direction from the file 1 and obtains a consecutive hard copy 7.

Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention divides an image (picture) displayed on a 017 screen into a plurality of parts, enlarges them, continuously takes note copies,
By joining these together, the screen can be enlarged.
The present invention relates to an enlarged notebook copy making device for obtaining a notebook copy.

(Prior Art) Conventionally, an apparatus is known that obtains a hard copy that corresponds 1:1 to an image displayed on a 017 screen. With this device, when trying to obtain a hard copy of an enlarged image, the image displayed on the 017 screen is sequentially enlarged, note copies of the image are sequentially obtained, and then each note copy is spliced together. . In this case, when joining the notebook copies one by one, the contact positions of each hard copy will differ slightly depending on the actual image condition, so judge these and remove the overlapping parts before joining. There is a problem that it is indispensable and difficult to handle.

(Objective of the Present Invention) The present invention has been made in view of the problems in the prior art, and it is an object of the present invention to provide an enlargement hardware and a copying device that can be easily spliced together.

(Structure of the present invention) The method according to the present invention includes a display file section storing image data to be displayed on a CRT, and a memory having a number of bits corresponding to the number of pixels constituting the screen of the CRT. In an apparatus equipped with a bitmap section in which data read out from the display file section is stored, and a hard copy creation section that reads out the data in the bitmap section and outputs a hard copy, the image data in the display file section is adapted to be compatible with a CRT screen. means for dividing and storing the grid blocks into a plurality of (m columns x n rows) grid blocks, and reading the data of the grid blocks from this display file using the grid blocks as one unit, and converting the data so that the data becomes a predetermined multiple. and means for obtaining a hard copy and thereafter sequentially reading and repeating the same operation for the data of lattice blocks adjacent to the previously read lattice block in the column direction or row direction. shall be.

(Embodiment) FIG. 1 is a block diagram of the configuration of an apparatus according to the present invention. In this figure, 1 is a display file section, which stores image data to be displayed on a CRT. 2
3 is a position 1 magnification calculation routine section that reads out necessary pixel data from the display file section 1, calculates position 1 magnification, etc., and creates screen data corresponding to the CRT screen, and 3 is a position 0 magnification calculation routine section 2. 4 is a bitmap section (video memory) into which screen data is input and stores this screen data in correspondence with the CRT screen; 4 is a CRT control section into which data read out from the bitmap section/3 is input; 5 is a CRT control section CRT whose display is controlled by 4
It is.

Reference numeral 6 denotes a hard copy data creation routine section connected to the bitmap section 5, and 7 a hard copy creation section connected to this routine section 6 to create a hard copy. Although each routine section 2.6 is shown here as a functional block diagram, it is assumed that each of them is realized by software.

In the apparatus configured in this way, in the display file section 1, image data as shown in FIG. 2 is stored divided into a plurality of grid blocks (eight blocks in this case). Do 2. The position 1 magnification calculation routine section 2 calculates (data conversion) the data of a specific grid block to a predetermined multiple according to the position 9 magnification calculation routine from within the display file 1, and converts the data to the screen of the CRT'5. The data are sequentially written into a bitmap section 3 having a memory with a number of pits corresponding to the number of pixels constituting the image. FIG. 3 shows data written to the bitmap section 3. Here, the data of the lattice block in the first row and second column in the display file 1 shown in FIG. 2 is read and stored.

The data stored in the bitmap section 3 is displayed on the screen of the CRT 5 via the CRT control section 4, and is output as a hard copy by the hard copy production section 7 via the hard copy data production routine section 6. . position 9
When the above-described series of operations are completed, the magnification calculation routine unit 2 automatically reads data from the display file 1 in the grid block adjacent to the specific grid block, for example, the data in the first row and third column. , is calculated to be a predetermined multiple, and the data is written into the bitmap section 3. The data written here is displayed on the screen of the CRT 5, and is also output as a hard copy from the hard copy creation section 7.

Thereafter, the position 0 multiple calculation routine part 2 sequentially starts from within the display file 1, for example, 1st row, 4th column → 2nd row, 1st column → 2nd row, 2nd column → 2nd row, 3rd column → 2nd row 4th row → 3rd row
Row 1st column......The data of the lattice blocks adjacent in the column direction are sequentially read up to the 4th row and 4th column, and the same operation as described above is repeated.
A continuous hard copy 71 as shown in the figure is obtained. Here, 72 is the number indicating the row of the grid block, and 73 is the alignment mark. shall be provided.

A hard copy as shown in Figure 4 is a line feed 7
By cutting the sheets at position 4 and pasting them together horizontally in the order of the numbers indicating the 91st row so that the alignment marks 73 match, it is possible to obtain an fc hard copy that is enlarged to a desired magnification.

FIG. 5 shows data in display file 1 arranged vertically by m.
12 is a flowchart illustrating an example of the operation of the apparatus when the image is divided into n pieces horizontally. In this flowchart,
In step 1, if enlarged copying is not specified, the process moves to step 2, and a flow for reading the notes on the screen currently displayed on the CRT is executed.

When enlarged copy is specified in step 1, the process moves to step 3, and a flow of obtaining an enlarged notebook copy by repeating steps 3 to 11 is executed.

The above explanation assumes that enlarged hard copies are output in correspondence with grid blocks that are continuous in the vertical direction (column direction) and pasted together horizontally. If the data is subjected to X4+Y conversion in the copy creation routine section 6, the enlarged node -
It is also possible to output tocobees corresponding to horizontally continuous lattice blocks.

(Effects of the present invention) As explained above, according to the enlarged copy making device of the present invention, continuous hard copies can be automatically obtained in the vertical or horizontal direction, greatly reducing the trouble of splicing. can be omitted.
