Abstract

PURPOSE:To form effectively new image information by synthesizing partially plural image information and to obtain its display and output by transferring the image information of a designated clipping area to a work area and subsequently, converting the size of the image information. CONSTITUTION:Image information from an input device 1 is stored in a memory 3 through a bus 13. This storage is executed by bringing the contents of an address counter 4 to an increment successively from the head address in the memory 3. Also, the head address and the horizontal direction length and the vertical direction length of the image information stored in the memory 3 are stored in a register 21. The image information in the memory 3 is stored in a memory 5 though the bus 13 and thereafter, displayed by a CRT 6. In such a case, a converter 8 reduces the image information from the bus 13 based on a horizontal/vertical direction conversion factor in a register 25 and by the command of a control device 7, the reduced image information is stored in a display area 5DE and given to the CRT 6.

The feature of the present invention is to specify an arbitrary area in the human image information and cut it out, and also to specify an arbitrary inset area in the three image information, so that the cut out image information matches the size of the inset area. The purpose is to convert the size to and insert it into the inset area.

First, the image information clipping process will be explained. Note that the image information in the image memory (3) is reduced and stored in the display memory (5).

The contents of the rear (5DE) and the cursor display area (50DE) where a cutting command signal is input from the keyboard (2) are superimposed and displayed on the CRT display (6). Further, a cursor of the control device is stored and displayed on the CRT display (6). This cursor can be moved by pressing the movement key C311-1 on the keyboard. Therefore, move the cursor to the desired position by pressing the movement keys ~ (to) as appropriate, and press the execution key 5.
When you press , this position becomes the starting position of the clipping area. , the start address 0ADI indicating this start position is stored in the cursor area register. Next, move the movement key (9
) to (to) to move the cursor horizontally or vertically from the top position to form a rectangular area, then press the execution key can, the rectangular area will be moved to the cursor display area (50DE) stored in C
displayed on the RT display (6).

This rectangular area indicates a cutout area, and its horizontal length Cx1 and vertical length CY1 are stored in the cursor area register [Yes].

Furthermore, when the execution key can is pressed, the control device α4 uses each data stored in the size conversion register and the cursor area register (to) to convert the image memory (3) corresponding to the above-mentioned rectangular area. The start address PAD2, horizontal length PX2, and vertical length PY2 indicating the image information area in
Store in. Then, by giving the start address PAD2 to the address counter (4), the image memory (3)
), the image information of the cropped area is read out from the data bus (
2) is stored in the work area (5WE). At this time, this image information is not size-converted.

Figure 5 (a) to (0) are schematic diagrams showing the procedure of such clipping processing, and (a) and (0) are the display memory (
5) in the same figure indicates the image memory (3). (
51) is a rectangular area specified by the cursor as described above, and (support) is an area in the image memory (3) corresponding to the rectangular area, that is, a cutout area, with a horizontal length M and a vertical length N. be. - is an area where the image information in the cutout area □□□ is stored without size conversion.

Next, a process for inserting image information cut out in this manner will be described. The image information to be inlaid is stored in the image memory (3) as described above, and information obtained by reducing this information is stored in the display memory (5). Further, the fitting information is stored in the work area (5WE) of the display memory (5) as described above.

In the insertion process, a rectangular area is formed by pressing the movement keys (9) to 载 and the execution key on the keyboard in exactly the same manner as in the above-mentioned cutout process. This rectangular area indicates the fitting area, and the starting address 0ADi, horizontal length OX1, and vertical length CY1 of the rectangular area at this time are stored as a cursor area register.

Then, when the execution key (g) is pressed, the control device α clause uses each data stored in the size conversion register and the cursor area register (text) to create an image memory corresponding to the rectangular area mentioned above. The start address PAD3, horizontal length PX3, and vertical length PY3 indicating the image information area in (3) are calculated and stored in the inset area register date.

Furthermore, the control device α calculates the horizontal length PX2 and the vertical length PY2 of the cropped image information stored in the clipping area register (2), and the horizontal length PX3 of the inset area stored in the inset area register (2). and the vertical direction length PY3, and read out the horizontal direction conversion rate HPR (=PX2/PX3) of the cropped image information and the vertical direction f
The conversion rate VPR (: PY 2/PY RO) is calculated and stored in the size conversion Regis game.

When such storage is completed, the display control device (7) reads the cut out image information stored in the work area (5WE) and transfers it to the size conversion device (8) via the interface@ and data bus. do.

The size conversion device (8) converts the transferred image information based on the horizontal conversion rate HPR and vertical conversion rate VFR stored in the size conversion register (2), and the data bus is connected to the interface I via the data bus. give to At this time, the start address PAD3 stored in the control device's inset area register is set in the address counter (4), and therefore the image memory (3) transfers the image information given to the interface circle to the image memory (3). ) is stored in the inset area.

FIGS. 6(a) and 6(b) are schematic diagrams showing such inset processing, in which the rectangular area specified by the cursor and the area in the image memory (3) corresponding to the rectangular area are shown in FIGS. , that is, the inset area, and has a horizontal length m and a vertical length n. Therefore, the image information (support) of horizontal length M and vertical length n stored in the work area (5WE) is converted into m/M in the horizontal direction and n/N in the vertical direction by the size conversion device (8). The size is converted and stored in the inset area (transfer).

As described above, the combined image information is stored in the image memory (3). This image information is stored in the display memory (5) as needed and displayed on the CRT display (6).
and is output to the image information output device (2).
