Description

DETAILED DESCRIPTION OF THE INVENTION A color graphic display device using the raster scan method has a configuration including a linear generator, a Ta II jA memory, a color matrix, and a video circuit.

The information obtained by the de-soto expansion of the coordinate values by the linear generator is
It is written to the video plane (FIG. 1) of the image memory. The image memory consists of a video plane and a color code plane, and the video plane (Figure 1)
When this information is written to the image memory, color code plane 1 (Figure 2), color code plane 2 (Figure 3), and color hood plane 3 (Figure 4) are written to the image memory.
The color codes necessary for accessing the color map are written into N sets of planes of the color code plane N (FIG. 5) corresponding to the coordinate values. For example, in the case of a line segment that has a slope of 45 degrees and is represented by 4 dots, the video plane (N
1), dots as shown in the figure are written. In the above case, if you want to express the line segment in red, use the color code corresponding to red, for example, color code plane 1 (Figure 2).
If color code plane 3 (FIG. 4) is at high level and the others are at low level, the color code planes 1 to N are written as shown in FIGS. 2 to 5. It is determined from the output of the video plane (FIG. 1) whether or not there is a single dot (8).

The output of plane N for color food (Figure 5) is the color code (9) whose color map you are about to access.
)become.

The present invention stores arbitrary code (10) in register (2).
The comparator (3) detects whether or not the set code (11) matches the color code of the color code planes 1 to N. If a match is detected, the gate circuit (4) is turned on by a signal (13) that changes from high level to low level with a certain period.

Turn it off. The gate circuit (4) allows high level,
A signal (14) that changes to a low level is supplied to the address of the color map menu (5).

As in the above example, if a line segment with a 45 degree inclination and represented by 4 dots is written to the image memory using a color hood that illuminates red, a code corresponding to red is written in register (2) in advance. If set, when the image memory output is fed to the color map memory address,
A comparator (3) detects a match, and a signal R (14) that changes from high level to low level is supplied to a color map memory (5). The color map memory (5) uses the output from the video plane (8), the color code plane (9), and the output (14) from the gate circuit (4) to create a map corresponding to red among the three primary colors of light. The signal corresponding to the color other than red is the signal (14)
It outputs alternately according to the period of change. The output signals (15), (16), and (17) pass through the D/A conversion circuit and are supplied to the monitor. As a result, a blinking effect occurs due to the change in ton'0. In the present invention, the two-image memory has been described as having a two-class configuration of a video plane and a color code plane, but the video plane i originally stores luminance information and multiple sets of different images, e.g. , 6□□ia, -60□ say. It is clear from this description that the blinking operation can be performed even if the configuration includes only the cloud-0-plane.

Claims (1)

[Claims] Color graphic display device number and I/X,
Regarding this method of expressing any color using a color hood (information that determines a color) and a color map circuit, a means for configuring the color map circuit with a memory element and a register for storing an arbitrary code are provided. The code entered in the register is compared with the code stored in the image memory, and when they match, different angles are generated alternately from the color map depending on the gate condition with a signal that opens and closes at an arbitrary cycle. A blinking method that changes color to create a blinking effect.
