Description

Detailed Description of the Invention (1) Technical Field of the Invention The present invention relates to a character display control method for a display device that has a character display section and a graphic display section and is capable of combining the character display and the graphic display including the characters. It is something.

(2) Prior art and problems (1) A conventional display device that can superimpose a character display and a graphic display including characters has a character generating part in a character display part and a graphic display part, and - A method is used in which the generated character pattern and the generated graphic pattern are read out from the graphic memory in which the butter 7 generated from the character generating section of the graphic display section is stored and displayed.

However, this method requires an expensive character generator.

For example, there was a drawback in that two kanji generation sections had to be provided.

(3) Object of the Invention The object of the present invention is to provide an inexpensive and efficient character display control system in which a character generating section is shared by a display device that can superimpose a character display and a graphic display that includes the characters.

(4) Structure of the Invention In order to achieve the above object, the character display control system of the present invention has a character display section and a graphic display section, and is capable of superimposing a character display and a graphic display for counting characters. (2) A character generating section is provided, and control is performed so that the latter character is displayed between xA where the former character is not displayed.

(5) Embodiments of the Invention The present invention temporarily stores code data for character display given to a character generation section, displays characters in the character display section, uses a period of 4'u, and displays the characters in the graphic display section. It is designed to contain bit pattern data for displaying characters.

FIG. 1 is an explanatory diagram of the configuration of an embodiment of the present invention.

In the same figure, a display device IfilJ# section 1 controls a display tR that can superimpose a character display and a graphic display including characters, and connects a character display section 22, a graphic display section 3, and a common bus 1o, which will be described later. connected by.

The character display section 2 contains the character code memory and the character control circuit 2.
From 8, character code memo! j2xld This is to store the displayed b character data in code format 'C. The single character system # circuit 22 receives the character code data from the display device control section 1, stores it in the character code memory 21, and displays it. Control is passed to the character display control circuit 4 (3).

The graphic display unit 6 is composed of a graphic memory 31 and a graphic control circuit 32. The graphic memory 61 stores bit patterns, and the graphic control circuit 62 is composed of a graphic memory 31 and a graphic control circuit 32. A bit pattern to be inserted into the graphic memory 61 is received), inserted into the graphic memory 61, read out for display, and passed to the display control section 6.

The character display control circuit 4 controls the character display section 2 during the character display period.
The data is read out, the character generation section 5 is controlled, and the character display data is passed from the character generation section 5 to the display control section B. During the horizontal return time, the character Data is successively generated, the character generating section 5 outputs a bit pattern corresponding to the character data, and the bit pattern is passed to the graphic display section 6, where 1iflJIl is performed.

The character generator 5 generates a character bit pattern by being given code data.

The display control section 6 converts the bit pattern received from the character generation section 5 and the graphic display section 6) into display data and sends it to the display f (CRT) 7.

That is, in the present invention, a common character generation s5 is provided in the character display section 2 and the graphic display section 6, and the character display section 2 and the character generation section 5 are controlled during the character display period, and K'' is added to the character code data.
A bit pattern t-2 is sent to the display control unit 6, and between this horizontal layer aAA, the graphic display unit 6 and the character generation s5 are controlled, the character code data received from the graphic display unit 3 is read out, and the corresponding The bit pattern is passed from the character generator 5 to the graphic display section 3.

'42 (α) to (c) show examples of screen displays according to the embodiment of the present invention.

FIG. 3(α) shows an example of character display that is controlled by the character display section 2, and FIG. Figure CO) shows a screen on which the bit patterns from both of these areas are displayed by the display control section 6.

As another embodiment of the present invention, when the character display control circuit 4 shown in FIG. The characters are stored in the graphic memory 31.

By adding a small amount of structure in this way, a new effect can be obtained, such as enlarging the characters one rotation.

(6) As described in detail, according to the present invention, since the character generating section can be shared by the character display section and the graphic display section, an inexpensive and efficient display section v1k can be obtained. In this case, in addition to obtaining the same high-quality characters in the character display section and graphic display section, the characters can be enlarged as described above.

Rotation can be easily controlled with a blade.

Claims (2)

[Claims] (1) In a display device that has a character display section and a graphic display section and can superimpose a character display and a graphic display that hides the characters, a character generating section that can be shared by the character display section and the graphic display section is provided, and the former A character display control method characterized by controlling the latter character to be displayed during a period when no character is displayed. (2) The character display control system according to claim 1, characterized in that the horizontal retrace period of the description/number 1 is used as the period in which the character t in the character narrowing portion is not displayed.
