Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a moving image processing method using a plurality of original images in which the display positions of a plurality of graphic symbols having fixed sizes can be changed.

(Technical background of development III and its problems) Previously, Fig. 4 (
As shown in A) and (B), a plurality of graphic symbols F consisting of a relatively large number of straight lines or curved lines with fixed sizes
When displaying the table/I< position of SI and FS2, for example, when displaying the graphic symbol FSI by 5 dots in the negative direction and the graphic symbol FS2 by 5 dots to the left, the 5th
In the CR7 display of the graphic dot information drawn in the video RAM as shown in the figure, it was necessary to erase the old symbols OFI and OF2 and display the new display positions NFI and NF2. In other words, in order to erase the graphic symbol at the old display position and draw the graphic symbol at the new display position, it is necessary to interpret and execute the command to erase or draw the sides of the straight line or curve that constitute the graphic symbol. was.

FIG. 6 is a block diagram showing an example of such a conventional video processing system, in which the graphic processing command unit l collects information about the individual line segments constituting the graphic symbol FS for performing the video, such as the starting point and ending point. Coordinate values, line types, etc. are read from the symbol line segment data registration unit 1O, a command for drawing the line segment or an erasure command LE in the case of erasing the symbol is generated, and this command LE is transferred to the graphic processing control unit 2. For each line segment, the graphic processing control unit 2 interprets the line segment drawing or erasing command LE generated and transferred from the graphic processing command unit 1, and calculates the CRT screen external coordinates (hereinafter referred to as device coordinates). Video RAM which is a memory element r for storing table small figures
4 and performs clipping processing on redundant areas as necessary. The command LE that has undergone these processes is then sent to the line segment drawing unit 3.
0, it is converted to jL-like dot information and stored in the video RAM.
Graphic focus information is stored in the corresponding position of 4. In addition, in the case of the line segment deletion command LE, the line segment drawing unit 30
Instead, the line segment erasing unit 31 converts it into specific rectangular dot information. It is designed to be stored on AM 4. The graphic information thus stored in the video RAM 4 is transmitted to the video signal 5) as a graphic display device in the generation unit 5.
Converts to a graphic display signal suitable for ZRT 6, CRT
6, and graphic symbols are displayed on screen 1-.

In this way, in conventional video processing methods, there are two methods, such as erasing the countryside-shaped Shinohoru and displaying the graphic symbol in a new display position.
Because it requires two steps, if colors or patterns are attached to the inside of the figure shift pole, there will be a noticeable delay in displaying the figure, making it difficult to express the smooth movement of the figure shift pole. In order to solve the problem of not being able to move, the graphic symbol FS to be moved and displayed is drawn only once at the beginning. A method has been devised to process video using

That is, in this method, as shown in FIG. 7, a non-display area NP of, for example, 5 dots is created around the graphic symbol FS to be moved and displayed.
0 Set the dot transfer area TA within the original image storage area,
The coordinates of an arbitrary point in the transfer area TA, for example, the cutting edge of a knife, are set as the reference point RP of the graphic symbol. and,
When performing video processing, the entire transfer area TA is transferred to the video RAM by instructing the transfer destination of the reference point RP of the transfer area TA to a desired address in the video RAM A.
4, and thereby the graphic symbol N at the new display position is displayed on the graphic display device from the old symbol OF to the new display position as shown in FIG.
Realize the video processing moved to F. In other words, by transferring the figure symbol p red 1 information to -1 to the new display position, the figure symbol dot information of 4. of the 111 symbol OF is changed to the new symbol NF or no display □! <Replaced with graphic dot information from any region MP, and as a result, 11.1 symbol OF is deleted. In this case, for example, 1-
5. If 1L row movement precedes. It is sufficient to repeat the video processing described in I-1 several times.

Figure 9 shows this method in action! This figure shows an example of a device that performs video processing. Graphic dot information is stored in a completed state as a symbol like the graphic symbol FS in FIG. Part l completely encompasses the graphic symbol FS, and the size of the transfer area including a small area HP in the necessary surrounding area and the coordinates 4/9 of the reference point RP during graphic symbol transfer.
The data necessary for the moving image processing is stored in the j;C7+ji data registration section 33 via the graphic processing control section 2. Then, the graphic symbol is transferred by one of the 31,712 original image transfer units from the graphic processing command unit 1 (updating of the latch point coordinates RP and video RAM 4).
Transfer of the graphic symbol FS and the entire non-display area NP, that is, the transfer area, is executed. At this time, the graphic processing control unit 2 updates the contents of the original image data recording unit 33 according to the spirit, transfers the graphic dot information in the specified area from the image storage area 32 to the video RAM 4, and The signal generator 5 generates a display signal to display graphic symbols on the CRT 6.

In order to simultaneously display a plurality of graphic symbols, for example, the two types of graphic symbols FSI and FS2 shown in FIGS. 4(A) and (B), on the CR7 screen, it is necessary to For each graphical symbol,
After sequentially registering the data in the original image storage area -() and the original image data registration 33, it is sufficient to repeat the process of executing the original image transfer command 1''PT for the graphic symbol FS.

This method I) deletes the above-mentioned III Shinhol OF,
Compared to the new method of displaying the figure S〉'pol NF,
・As mentioned earlier, the original image storage area 32 and the I! Since only one type of graphic symbol FS can be stored in the n-picture data Q recording section 33, if there are many graphic symbols FS to be processed in a moving image, the original picture can be saved and J', i pl! Since data 0 recording must be performed frequently, the disadvantage is that the video processing speed slows down.

(Object of the Invention) The present invention was made based on the above-mentioned view, and the uninvented object is to solve complex graphic symbols in which colors and patterns are old inside one figure.
