Abstract

PROBLEM TO BE SOLVED: To reduce the capacity of a memory section by storing a character image viewed from one eye for a horizontally symmetric character in a game apparatus in which a displaying of a stereo image is performed by a display with parallax between two display parts. SOLUTION: A character is viewed from the direction of a right eye is stored into a character ROM for a horizontally symmetric character. In display, the horizontally symmetric character read out by a reading section 10 is inverted by an inversion part 11. A character for right or left position is held in a buffer memory 12 and displayed at a pair of display pars through a color control section 14 and a parallax control part 15. This enables a player to view stereoscopically. It is sufficed to store a character viewed from one eye side for the horizontally symmetric character thereby curtailing the capacity of a memory circuit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game device having a right-eye display unit and a left-eye display unit for stereoscopic display by parallax display, and more specifically, it can reduce the capacity of a memory used in the game device. The present invention relates to a stereoscopic image display game device.

[0002]

2. Description of the Related Art Conventionally, when a game device such as a space inbeta game is displayed three-dimensionally, characters such as an invader as viewed from the right and a character as viewed from the left are individually stored in a character ROM or the like and are individually stored. The three-dimensional display was performed by reading out and displaying on the display units for the right eye and the left eye. Figure 4 shows the left-eye character in (a),
The characters for the right eye are shown in FIG.

[0003]

The conventional stereoscopic image display on a game machine has a drawback that the capacity of the memory becomes large because one character is stored in the memory portion, and the left and right characters are stored in the memory portion. . An object of the present invention is to store a character image viewed from one eye for a bilaterally symmetrical character in a game device that displays a stereoscopic image by providing parallax between two display units. The object is to provide a stereoscopic image display game device in which the capacity of the memory unit is reduced.

[0004]

In order to achieve the above object, a stereoscopic image display game apparatus according to the present invention is provided with a right eye display section and a left eye display section, and a right eye display apparatus for stereoscopic display by parallax display. Alternatively, a memory unit that stores the left-right symmetric characters when viewed from the left eye, an inversion unit that inverts the left-right symmetric characters read from the memory unit, and a buffer that temporarily stores the left-right symmetric characters inverted by the inversion unit. Displaying display data from a memory, a parallax control unit that gives parallax to the left-right symmetric character when viewed from the right eye and the left-right symmetric character when viewed from the left eye, and display data from the parallax control unit. It is composed of a pair of display parts.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit diagram showing an embodiment of a circuit of a stereoscopic image display game device according to the present invention, which is an example applied to a space invader game. When the game machine is activated by the player's operation, the CPU 1 reads an operation program for executing the space invader game from the program ROM 6 via the system bus 2 and starts executing the operation program. The character is read from the character ROM 7, the CPU 1 performs a process for stereoscopic viewing, the screen memory 8 stores the left and right characters, and the display unit 9 displays the left and right eyes for viewing.

Input signals from the buttons of the operating device 4 are sent to the CPU 1 via the input / output control circuit 3. Work RA
M5 is used as a work area of the CPU 1. FIG.
The control unit C of the stereoscopic image display game apparatus according to the present invention
It is a figure which shows the functional block of PU. Character ROM
In Fig. 7, for example, in the case of the letter "A", a view of "A" shown in Fig. 3C from the left side of the center, that is, Fig. 3A.
“A” such as is stored.

When "A" is displayed on the display unit 9, "A" shown in FIG.
It is read by 0 and is inverted by the inverting unit 11 as shown in FIG. 3B as viewed from the right eye. Writing / reading unit 1
3 temporarily writes “A” for the left eye and the right eye in the buffer memory 12. Then, the writing / reading unit 13 reads from the buffer memory 12 at a predetermined timing, and the color control unit 14 controls coloring. The parallax control unit 15 sets “A” at the timing of providing parallax to “A” for the left eye and “A” for the right eye.
Is displayed on the display unit 9. The player can see stereoscopically by seeing “A” from the left and right display portions of the display unit 9.

[0008]

As described above, according to the present invention, the characters seen from the right eye or the left eye are stored in the character ROM, and the right and left eyes are reversed at the time of display to create the characters for the right eye and the left eye. The display is displayed by a parallax control unit for stereoscopic viewing. Therefore, the amount of symmetrical characters stored in the character ROM can be reduced by half as compared with the conventional case, and the number of memory circuits can be reduced.
