Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a graphic display control method for a raster scan type display device. Advances in processing technology have made it possible to process complex tasks or to convey complex and advanced information to humans through imaging, and also to display rounded figures to effectively communicate the results of such processing to humans. Although complex auxiliary display functions are used in the equipment, image processing is usually performed interactively, and in such cases it is especially difficult to display processing results in a timely manner. 0 (C) Prior art Tasters/Yang type display devices use a buffer memory (usually referred to as a seven-dimensional memory) that stores display data for each pixel that makes up the display screen. Normally, the contents of this backup are sequentially accessed and stored in the 0 displayed on the display, that is, the data displayed on the display and the data stored in the backup. The data are completely consistent. In order to perform some kind of temporary processing on some data on the display tiim, such as this rounding blinking or pickup, it is necessary to change the storage contents of the backup memory, which may prevent timely data display. This was a contributing factor.

(D) Object of the Invention The object of the present invention is to develop a graphic that can quickly display blinking, pickup, and temporary processing of some data on the display screen without changing the memory of the buffer memory. There is a need to obtain a display control method.

(K) Invention'II! The graphic display control method of the present invention includes: a different display section, a plurality of buffer memories provided corresponding to the display surface of the display section and storing display data, and display data stored in the plurality of buffer memories. There are multiple calculation units that perform calculation processing. 24,7a, □This is one of the plurality of buffer memories, in which the stored display data is taken out sequentially corresponding to the pixels, and the data obtained by performing arithmetic processing on each other is displayed. When performing some kind of temporary processing on some data on the display screen by using it as a memory similar to glue fresh memory and using the other memory as a memory to temporarily store the contents of other display layers, 〇(F) Embodiments of the Invention The following embodiments of the present invention are shown in the @ side. I will give a concrete explanation of the gist.

FIG. 1 shows a conceptual diagram of a tenth embodiment of the present invention.

In the figure, 1 is an interface circuit with the central CPU (CPU), 2 is a control circuit that interprets CPU0 control commands and controls the device, and 3 is a control circuit that operates the buffer memory (described later) according to control signals from control circuit 2 to display display data. 4 is a control circuit 20 which performs writing or reading 9, etc.
Calculation to be performed by the calculation section described below in response to a control signal OVTI class pipe designation page blind register, 6 and 6 CR
The buffer memory of the irises, which is provided corresponding to all the pixels constituting the display surface of the T and stores display data, and the #! 2 is a buffer memory; 7 is an arithmetic unit that performs nine operations specified by the register 4;
8 is a parallel-to-serial conversion circuit, and 9 is a CRT used as a display section.

In the above configuration, the first buffer memory 5 is used in the same manner as the leaflet memory in the conventional example, and stores basic display data, and the second buffer memory 6 stores the first buffer memory 5. It stores data corresponding to temporary display processes such as blinking, reverse pickup, superimposition, etc. applied to the basic display data stored in the memory. In addition, the operation register 4 stores operation codes such as logical sum (OR), logical product (AND), exclusive sum of disjunctions (EOR), and non-operational (NOP). We will explain various display processing examples by.

The arithmetic unit 7KMjl performs a product operation and displays the logical product of the data stored in the first buffer memory 5 and the data stored in the second buffer memory 6 on the CRT9. It can be extracted and displayed. In this case, the extracted display data may be stored in the second buffer memory 6.

The arithmetic unit 7 performs the exclusive OR operation and the first tD/

Furthermore, by disabling the calculation section 7 from performing calculations, the data stored in the first buffer 5 can be displayed on the CRT 9 as is. (a) h*

(d) shows an example of deletion or blinking of figures by exclusive OR, (.) shows an example of reverse display by exclusive OR, and (f) shows an example of non-operation.

FIG. 3 shows a conceptual diagram of the second embodiment of the present invention. ), blue (B) multi-plane forgery, and three-color display is possible, and is the same as that explained in Fig. 1 of the other code companies. The operation register 4 not only specifies the type of operation to be performed by the calculation section 7, but also specifies the color plane to be subjected to the operation. By adopting such a structure, it becomes possible to carry out various display processes, display color selection, and background color selection in the first embodiment. In addition, even if the first buffer memory 5' has a multi-plane structure in the second embodiment, there is no guarantee that all the second buffer memories 6 have a multi-plane structure.

(G) Effects of the Investigation As explained in the embodiments, the present invention allows temporary effects such as blinking, reverse pickup, superimposition, etc. to be applied to the basic display data described above. The time required for display processing is shortened, and therefore processing results can be displayed in a timely manner.

A variety of Ojii! There is no fear of destroying the basic display data in the demonstration.
