The graphic status data circuit 6, the graphic data RAM 7, and the animation control device 9 store and output the data of the moving image to be displayed in the still image. When the moving picture pattern is designated by the keyboard or the joystick 2, the input control circuit 4 secures the status area of one moving picture in the graphic status buffer 6-1 in the graphic status data circuit 6.

FIG. 2 shows a graphic status buffer 6-corresponding to one moving image.
In the memory structure of the area (second area) secured in 1, each area consists of 13 bytes, and FIG. 2 shows the second area of A13 to A25. The attribute A13 is data indicating whether the name of the moving image, that is, the character name is self (1) or non-self (2), and is data to be distinguished and controlled by the animation control device 9. Following the Attribution A13, the character name, the presence / absence of a direction, and the size (size of the moving image) are so-called attribute data, and then the direction pointer (upper, upper, right, right table,
The right side, the lower side, the lower side, the left side, and the left side), and the character information address pointer are arranged in this order.

The graphic status buffer 6-1 stores a pointer for designating a storage position of each data stored in the graphic data RAM 7 and the character information buffer 6-2 in the graphic status data circuit 6 in addition to attributes and character names. is there.

FIG. 3 shows the character information buffer 6-2 and the graphic data RAM 7 designated by each pointer of the graphic status buffer 6-1.
It is a memory block diagram showing.

The graphic data RAM 7 is a memory for storing the graphic in each table, for example, in each direction, and the top address of the area where the graphic data is stored is the graphic status buffer 6-1.
Stored in each direction pointer of. In the embodiment of the present invention, when the data stored in each of the directional pointers on the upper side to the left side of the figure status buffer 6-1 is 0, it means that there is no figure data, and when it is other than 0, the value is the figure data.
It represents the address of RAM7 of RAM6-2. Graphic data RA
The address that indicates M7 is stored in the above table to the left table (A1
7 to A24), and the address pointer of the character information buffer 6-2 in the graphic status data circuit 6 is stored in the address A25.

The character information buffer stores additional information of each character, that is, a moving image. For example,
The appearance position coordinate direction on the screen, the current display position coordinate, moving speed data, etc. are stored.

The data to be stored in the graphic status buffer 6-1, the character information buffer 6-2, and the graphic data RAM 7 in the graphic status data circuit 6 are the data input from the keyboard 1 and the joystick 2, and the data input from this input section. Is first taken into the input control circuit 4. Then, under the control of the input control circuit 4, the data is stored in the target position via the address lines Ad ₄ , Ad ₅ , and the data lines Da ₄ , Da ₃ .

FIG. 4 is a flow chart of the procedure for storing the data input from the keyboard 1 and the joystick 2 in the graphic status buffer 6-1, the character information buffer 6-2, and the graphic data RAM 7. When creating a new character, first enter attribute data (S ₁ ). Then, a newly created area is secured from the beginning of the empty area of the graphic status buffer 6-1 and the attribute data by the input (S ₁ ) is stored in the target position (S ₂ ). Note that the attributes include (0) in addition to (1) and (2) described above. When the attribute is (0), it is an empty area, and the figure status data is fixed in units of 13 bytes, for example. The contents of the attribute are sequentially determined and the area is secured in the area (0). The graphic status buffer shown in FIG. 2 represents the second area. Next, initialize the selection cursor coordinate register 10 and figure status data pointer register 11 connected to the input control circuit (S ₃ , S ₄ ).
I do. Selection cursor coordinate register 10 is a register for storing a coordinate value that specifies the selection cursor to be displayed on the display unit, displaying a selection cursor after the initialization coordinate values of the selection cursor coordinate register (S ₅₎ to. The graphic status data pointer register 11 is used for the graphic status buffer 6-
It is a register for storing a value indicating any address of the directional pointers in the front side to the left side in each area of 1. Then, to display the graphic pattern of the direction of the registered indicated by the selection cursor coordinate register 10 (S _6). The graphic pattern displayed at this time is the content of the graphic data RAM 7 indicated by the content of the graphic status buffer 6-1 designated by the selection cursor as shown in FIG. A graphic representing eight directions as shown in FIG. 5 is displayed on a part of the display screen of the CRT 13 by the input control circuit 4, and the cursor indicates the direction of the graphic to be input or being displayed. To be done. The position of this cursor is determined by the contents of the selection cursor coordinate register 10 described above. For example, when initialized, the above table is designated as shown in FIG. Incidentally, when no direction is designated, only two pairs of front and back are designated, and in this case, for example, either the front or the back will be lit. This cursor is moved by data entered by the keyboard 1 or joystick 2, then the selection cursor movement is determined whether an instruction by a keyboard 1 or joystick 2 described above (S _7).

When the selected cursor movement is instructed (YES), updates the coordinates of the selection cursor coordinate register (S _8), further updates the graphic status data pointer register value (S _9),
The selection cursor is displayed again at the position designated by the selection cursor coordinate register, that is, the coordinate value (S ₅ ). Above steps
The update process of S _{9 is} a process of updating the value of the figure status data pointer register 11 to the same value as the updated value of the selection cursor coordinate register 10 updated with the cursor movement in step S _8. By the processing, the value of the graphic status data pointer register 11 is a value corresponding to the cursor direction selected this time, that is, the address of any of the directional pointers from the upper table to the left back in each area of the graphic status buffer 6-1. It is the value to point to. Then, while the cursor is moving, the above operation is repeated.

The above-mentioned determination (S ₇ ) operates when data is input by the keyboard 1 or the joystick 2, and when it is not data for instructing the movement of the selection cursor (NO), processing for inputting graphic data is performed. First, graphic data RAM7
It is determined whether or not the area for storing the graphic data is secured (S ₁₀ ). This determination (S ₁₀ ) is performed by determining whether the stored value of the address of the graphic status buffer 6-1 designated by the graphic status pointer register 11 is 0 or not. When the area is secured, data input (S ₁₁ ) is performed and the input data is stored in the graphic data RAM area of the content of the graphic status buffer 6-1 designated by the graphic status data pointer register 11. When the area is not secured, first, the value stored in the graphic data empty area pointer register 12 connected to the input control circuit 4 is indicated by the value stored in the graphic status data pointer register 11. The data is stored in any of the directional pointers on the front side to the left side in each area of 6-1 (S ₁₂ ). Then, update the data stored in the graphic data empty area pointer register (S ₁₃₎ to. This update is performed by adding the address value of the screen data in one direction to the current data. Figure data empty area pointer register 12
Stores the start address of the empty area of the graphic data RAM 7 as shown in FIG. 3. Therefore, by simply storing the value of this graphic data empty area pointer register 12 in the graphic status buffer as described above, It has been secured.

Since the area has been secured by these processes (S ₁₂ , S ₁₃ ), the above-mentioned data input (S ₁₁ ) is performed to store the direction pointer currently designated in the area of the graphic status buffer 6-1. Store the input data in the graphic data RAM area at the address indicated by the value.

Then, the all graphic data input completion determination of whether or not (S _14). When it is completed (YES), it ends (S ₁₅ ),
When not completed performs processing selection cursor displayed on the coordinate values of the selection cursor coordinate register (S _5), and repeats the operation described above. In the figure Is a connector that indicates that processes are connected.

The processing flow described above is a newly created processing flow.
When adding or modifying the illustrated data, the same operation is performed except that the processing at the initial time is different. In this case first, input of a character name the (S _16). And to search for shapes status buffer (S _17), it is determined whether or not the entered character name exists (S _18).

If it does not exist (NO), the input process (S ₁₆ ) is performed again. When it exists, the same process as the above-described process is performed from the process of initializing the selection cursor coordinate register (S ₃ ).

The above-described process is a process of inputting graphic data of a moving image, and is not a process of displaying and moving a moving image pattern in a display image. To control these displays and movements,
The animation control device 9 and the display control unit 8 are controlled by the input control circuit 4. The animation control device 9 is a device for performing control to output display data from the graphic data RAM according to a control signal applied from the input control circuit. The display scanning data output from the refresh address control circuit of the input control circuit 4 is added to the animation control device 9, and the animation control device corresponding to the data, the appearance position coordinates stored in the information buffer 6-2, Each data of the direction and the moving speed is read out through the address line Ad ₅ and the data line Da ₅ to obtain the current display position coordinates. Then, the current display position coordinates are stored in the information buffer 6-2 via the address line Ad ₆ and the data line Da ₅ . Since the coordinates of the current display position are made in correspondence with the above-mentioned display scan data, that is, in units of one display (one screen),
The coordinates of the current display position change correspondingly.

From this data, the graphic status data circuit 6 accesses the graphic data RAM ₇ corresponding to the display scanning data, that is, the graphic data RAM ₇ corresponding to a specific position on the display screen through the address line Ad ₇ , and the graphic data is added to the display controller 8.

The respective data output from the pattern generator 5 and the graphic data RAM 7 to the display control unit 8 are dot data and color data corresponding to scanning. Display control unit 8
Has a color generation circuit and a palette circuit respectively corresponding to the above-mentioned two inputs, obtains the target display color data from the color data, color-paints the dot data in the palette circuit, and outputs the video data. create. The above-mentioned data are not displayed at the same time. For example, since the device for a moving object must be turned off, the display control unit 8 has a selection circuit, and when data such as a moving object is input from the graphic data RAM 7, It is designed to be selected and displayed.

Since the above-mentioned operations are all digital processing, the output of the selection circuit is converted into an analog signal by the D / A circuit in the display control unit 8 and added to the CRT 13 to be displayed on the screen.

〔The invention's effect〕

According to the present invention, for example, it is not necessary to individually input moving image attribute data with respect to a plurality of moving image graphic data depending on directions, and for example, by simply specifying a direction with a cursor or the like, a plurality of moving images in different directions can be displayed. It becomes possible to input graphic data easily and accurately.
