Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a picking processing circuit for a CRT display device, and particularly to a picking processing circuit for a CRT color graphic display device. This circuit relates to a binning processing circuit that specifies the specified partial figure using the input H11'X (by -).

DESCRIPTION OF THE PRIOR ART FIG. 1 is a schematic block diagram of a conventional Raster Gann) 11'' granoic display device. , 1: First, referring to FIG. 1 [), the operation of the conventional rask scan type graphic display device will be briefly explained in section 1. Data is provided to the graphic data management unit 3 via a transmission line that connects the host computer 1h and the host interface 2. The graphic data tube il1 section 3 receives data from the host computer coater 1 and can display the data as a graphic. 1. Rearrange the shapes into 1, give each figure an identification number and priority, and do not show them in the diagram.1. I remember 1" in the memory of the program.

The data analysis section 4 extracts the contents of the IZgmen l-buffer, analyzes the data, and performs a vector operation based on the starting point coordinates and the ending point coordinates. Then, the coordinate conversion clip section 5 performs the necessary multiplication of the data of 71-rix and i when enlarging, reducing, one rotation, or translating the figure. Also, when a part of a figure on the CRT display screen is surrounded by a frame, the figure that protrudes by 1L from the frame is clipped. When the figure is not filled in, the ODA control filling section 6 generates line segments decomposed into inner lines from the coordinates of the rectangular points of each vector, and fills in the filling data thereby. DD△7 is a straight line generator that generates a straight line, and based on the data from the DI) AIII n11 filling section 6, it generates a vector connecting the starting point and the ending point ((
The coordinates along the way are expanded and expanded into the image memory 8 to form a straight line. Image, mail [su8#, LD

It is something that The data stored in the image memory 8 is transferred to the video control unit 9, where it is converted into an analog signal by D7/Δ conversion and converted into a video signal based on a color conversion table, and the video signal is converted into a color It is given to seven nits and ten.

As a result, the color monitor 10 displays a graphic based on the data output from the computer 1 (small stroke=1).

Figure 2 is shown in Figure 1/, :CRr Color Gra-7-(
This is a diagram showing an example of a graphic displayed on the monitor 10 when the display is installed in color. FIG. 3 is for explaining the operation of selecting the graphic shown in FIG. FIG. Next, the picking processing operation for identifying the figure 12 displayed on the screen of the color monitor 10 will be explained. As described above with reference to FIG. 1, the segment buffer of the graphic data management section 3 stores lit graphic data, an identification number of the graphic data, and a priority order. Further, the color graphic f' display device is provided with an instruction section 11 such as a pen, etc., as shown in FIG. Then, in the microphone included in the graphic data management unit 3 [1 processor is abbreviated as the step shown in FIG. '(?Gumen) Clear the identification number area, read and save the first segment identification number from the segment buffer in step SP2, and save the priority of the segment in step SP3. Then, in step SP/'I, a dummy straight line is generated using the graphic data of the segment by I)L)7.

-〇~ At this time, it is checked in step SP6 whether or not the generated straight line passes through the area specified by the △ points on the screen of the color monitor 10 (this state is hereinafter referred to as the 111 king state).
Discrimination is reversed. If the straight line does not pass through the designated area, it is determined in step 5P10 whether or not the picking process for all the bearded men 1 to 1 has been completed. It' 7 [If j, step S

The graphic data management unit 3 recognizes that there is no graphic to be processed.

Here, in Fig. 2, if you specify point A, you can understand that you are specifying figure 12, but two figures 12 and 13 are displayed on the screen so that they intersect, and you specify the 8 points of intersection. In this case, it is not possible to identify which of the two figures 12 and 13 was specified.

In order to eliminate this inconvenience, priority is given to each figure. That is, figure 12
If the priority of the figure 13 is lower than that of the figure 13, for example, if 8 points is specified, the figure 12 is designated.

Therefore, when it is determined in step SP6 that 1li1 has been performed, Hi i' is determined in step S1]7.

Purpose of the Invention 10- Therefore, the main purpose of the present invention is to perform the picking process, which was previously performed software using a program, using a bird drawer configuration, thereby making it possible to perform high-speed processing. The purpose of the present invention is to provide a picking processing circuit for a CRI-DIB1 noise device.

Coincidence of the invention To summarize this invention, storage in segment buffer 1)

EFFECTS OF THE INVENTIONSONG As described above, this invention provides a method for sequentially reading out a plurality of graphic data stored in segment 1 to buffers, their respective identifications and priorities, and storing them in a storage means. The first read data out of the plurality of stored data is stored in the first -I1. '1 storage means, and sets a number in the second temporary storage means corresponding to this first temporary storage means.

Then, a straight line is generated in a pseudo manner based on the graphic data read from the storage means, and it is determined whether or not the straight line A passes through the designated area. Compare the priorities stored in the first row,
If the priority level of the first temporary storage level is high 1, the priority level of the first temporary storage means is stored in the second temporary storage ffi.
Since the data is transferred to the second temporary storage means, the data analysis means can perform picking processing at high speed based on the contents of the second temporary storage means. In other words, even if there is a large amount of graphical data, the data analysis means can calculate the second straight line generation without making any necessary adjustments such as whether the means has finished generating a straight line or whether it has reached l-1+. By determining the contents of the temporary storage means (), the indicated figure can be identified.
