Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to an image (picture) displayed on a CRT screen.
The present invention relates to an enlarged hard copy production device that obtains a hard copy with an enlarged screen by dividing and enlarging a screen into a plurality of parts, continuously taking hard copies, and splicing the hard copies.

(Prior Art) Conventionally, an apparatus is known that obtains a hard copy that corresponds 1:1 to an image displayed on a CRT screen. With this device, if you want to obtain a hard copy of an enlarged image, use the CRT
The image itself to be displayed on the screen is sequentially enlarged, hard copies of the image are sequentially obtained, and then the hard copies are stitched together. In this case, when joining the hard copies one by one, the contact positions between 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 enlarged hard copy creation device that can be easily spliced.

(Structure of the present invention) The device according to the present invention has 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 comprising a bit map section in which data read out from the display file section is stored, and a hard copy creation section using continuous paper for reading out the data in the bit map section and outputting a hard copy, the image data in the display file section is means for dividing and storing the data into a plurality of lattice blocks (m columns x n rows), reading the data of the lattice block from the display file section with each lattice block as one unit, and converting the data to a predetermined multiple. and a means for obtaining a hard copy and thereafter sequentially reading data of grid blocks adjacent to the previously read grid block in the column direction or row direction and repeating the same operation. This is a special feature of this large hard copy production device.

(Embodiment) FIG. 1 is a block diagram of the configuration of an apparatus according to the present invention. In this figure, 1 is a disk play file section, which stores image data to be displayed on a CRT. 2 is a position and magnification calculation routine section that reads the necessary image data from the display file section 1, calculates the position, magnification, etc., and creates screen data compatible with the CRT screen; 3 is a position and magnification calculation routine section that reads the necessary image data from the display file section 1; A bit map section (video memory) into which screen data is input and stores this screen data corresponding to the CRT screen; 4 a CRT control section into which data read out from the bit map section 3 is input; 5 a CRT control section 4; Therefore, it is a CRT whose display is controlled.

Reference numeral 6 denotes a hard copy data creation routine section connected to the bit map section 5, and 7 a hard copy creation section connected to this routine section 6 and using continuous paper for creating hard copies. Although each routine section 2, 6 is shown here as a functional block diagram, it is assumed that they are both realized by software.

In the apparatus configured in this way, it is assumed that image data as shown in FIG. 2 is stored in the display file section 1 divided into a plurality of grid blocks (8 blocks in this case). . The position and magnification calculation routine unit 2 calculates (data conversion) the data of a specific grid block to a predetermined multiple according to the position and 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 the bit map section 3 having a memory with a number of bits corresponding to the number of pixels constituting the image. FIG. 3 shows the 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 out and stored.

The data stored in the bitmap section 3 is
The data 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. When the above-described series of operations are completed, the position and magnification calculation routine unit 2 automatically extracts data from the display file 1 from the grid block adjacent to the specific grid block, for example, the data in the first row and third column. The data is read out, calculated to be a predetermined multiple, and the data is written into the bit map 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/multiply calculation routine section 2 sequentially moves 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 column → 3rd row, 1st column...The data of the lattice blocks adjacent in the column direction are sequentially read up to the 4th row, 4th column, and the same operation as described above is repeated, and from the hard copy creation unit 7, the data of the 4th column is read. A continuous hard copy 71 as shown in the figure is obtained. Here, 72 is a number indicating the row of the lattice block,
Reference numeral 73 indicates alignment marks, which are written on the bitmap 3 in synchronization with data reading from the display file 1.

A hard copy as shown in FIG. 4 is enlarged to the desired magnification by cutting the paper at the line feed 74 and pasting them side by side in the order of the numbers indicating the lines so that the alignment marks 73 match. You can obtain a hard copy.

FIG. 5 is a flowchart showing an example of the operation of the apparatus when the data in the display file 1 is divided into m pieces vertically and n pieces horizontally. In this flowchart, if you do not specify enlarged copy in step 1, the process moves to step 2 and the current
Execute the flow to obtain a hard copy of the screen displayed on the CRT.

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

Note that the above explanation assumes that the enlarged hard copies are output in correspondence to continuous lattice blocks in the vertical direction (column direction) and pasted together horizontally, but the hard copy creation routine If the data is subjected to X→←Y conversion in section 6, enlarged hard copies can be output corresponding to grid blocks that are continuous in the horizontal direction.

(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.
It can save you a lot of effort in splicing.
