Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic amusement machine, and more particularly, it holds information relating to a display object as three-dimensional cubic data, and performs a three-dimensional arithmetic processing on the information to display all the display objects. The present invention relates to an electronic game machine that can be visualized as an object that can be viewed from a viewpoint.

[0002]

2. Description of the Related Art In a conventional electronic game machine, image information displayed on a display device is information on a two-dimensional plane.
The so-called pictures were continuously projected to create a dynamic continuous image. According to this conventional display method, all objects drawn are based only on a two-dimensional picture, and there is no concept of the presence of a light source or the viewpoint of a camera.

By the way, recently, a method of displaying by adopting three-dimensional information as display image information has begun to spread, by developing the conventional display method as described above. That is, according to the method, since it is three-dimensional information, an object represented by image information can be regarded as a three-dimensional object and the concept of a viewpoint can be introduced. All displayed objects are three-dimensional information (X, Y,
Z), and can perform their arithmetic processing. If a certain point on the three-dimensional coordinate axis is determined as a viewpoint by introducing the concept of a viewpoint (a position where a camera is located), an image of a target object viewed from that position is displayed on a display device. In addition, by moving the coordinates of the viewpoint, the viewpoint can be changed continuously or stepwise, whereby it becomes possible to display any position in the three-dimensional space as a viewpoint on the display device. This is a technology called so-called virtual reality (virtual reality or pseudo-world, etc.).

According to this technique, an arbitrary three-dimensional world can be simulated by three-dimensional manipulation of image information, and as described above, the introduction of the concept of a viewpoint enables camera work that does not actually exist. At the same time, the concept of the viewpoint made it possible to realize an image with a light source placed at an arbitrary position. Also, gravity, pressure in three-dimensional space,
It has the potential to freely set various balances such as friction resistance. Such technology is inevitably being adopted in electronic game machines.

[0005]

By the way, in the conventional electronic game machine for displaying two-dimensional image information on the display device, for example, in a so-called driving game, the viewpoint relating to the displayed image is the viewpoint of the driving vehicle of the car. That is, it is fixed from the viewpoint of the athlete. Further, even in an electronic game machine having a plurality of such viewpoints, it is the programmer's intention at the time of creating the game program that changes the viewpoint, and the viewpoint is fixed at the time of creating the program. Is never reflected. Furthermore, changes between multiple viewpoints were also gradual.

Therefore, if the above-described three-dimensional space display technology is adopted in an electronic game machine, it is possible to display a video from any viewpoint of the three-dimensional space related to the displayed image information.

The present invention has been made under the circumstances as described above, and an object of the present invention is to change the viewpoint of an image displayed on a display device according to the competitive posture of a competitor or arbitrarily. It is to provide an electronic game device that can be used.

Embodiments of the present invention will be described below in detail with reference to the drawings.

By the way, according to the present invention, as described above, the information regarding the display object is held as three-dimensional stereoscopic data, and the three-dimensional arithmetic processing is performed on the information, so that the display object can be viewed from all viewpoints. The present invention relates to an electronic game machine that can be visualized as such an object.

FIG. 1 is a block diagram showing the configuration of an embodiment of the electronic game machine of the present invention. A driving game will be described as an example. As in the conventional case, when the athlete performs a driving operation, a signal from the driving operation device 5 is input to the image processing and arithmetic processing board 1, and the processing is performed there. After that, the display device 4 is based on the processing result.
The image displayed on changes. That is, the scenery, background, etc. change according to the driving of the athlete. By the way, according to the present invention, the viewpoint changing switch 2 for allowing the athlete to arbitrarily change the viewpoint of the display image and the photoelectric sensor for attitude detection for detecting the competition attitude for changing the viewpoint of the display image according to the competition attitude of the athlete. Sensor group 3 is established. In both cases, the output signal is input to the image processing and arithmetic processing base 1.

First, the case of using the viewpoint changing switch 2 will be described. That is, this is a case where the viewpoint of the display image is changed based on the will of the athlete. The viewpoint changing switch 2 may be provided in parallel with the game start switch, or may be provided on the steering wheel. In addition, the game start switch may also function as the viewpoint changing switch 2 after the game is started, so that the game start switch also functions as the game start switch.

Here, some viewpoints are determined and set in advance. 3 (A), (B) and FIG. 4 (A),
(B) is a diagram showing the determined viewpoint of the driving game. As shown in the figure, for example, four viewpoints are set, viewpoint 1 is “slightly behind the vehicle”, viewpoint 2 is the “competitor (driver) viewpoint”, viewpoint 3 is “low behind the vehicle”, viewpoint 3 4 is "high above the vehicle". The setting to the device is performed by giving concrete three-dimensional coordinates of those viewpoints. Therefore, in the case of using the viewpoint changing switch 2, for example, it is sequentially switched each time the switch is pressed. That is, viewpoint 1 → viewpoint 2 → viewpoint 3 → viewpoint 4 → viewpoint 1 and so on. At this time, the movement from one viewpoint to the next viewpoint is continuously performed by a method in which the viewpoint gradually moves while processing the three-dimensional data.

FIG. 2 is a flowchart showing a processing procedure in the image processing and arithmetic processing base 1 at that time.
Therefore, it is first determined whether or not the viewpoint changing switch 2 is pressed (step S21), and when it is judged that the viewpoint changing switch 2 is pressed, the viewpoint data is changed to the next viewpoint data (step S2).
2). On the other hand, if it is not pressed, step S is performed as it is.
Move to 23. In step S23, it is determined whether or not the current camera position and the camera position based on the viewpoint data match. If it is determined that they do not match,
The position of the camera is brought closer to the position based on the viewpoint data (step S24).

In the case of the viewpoint changing switch 2 as described above, the movement of the viewpoint is not limited to the sequential method as described above, and a method of arbitrarily selecting a certain viewpoint can be used.

Next, a case where the posture detecting photoelectric sensor group 3 is used will be described. FIG. 5 is a diagram showing the installation positions in the main body 90 of the individual sensors that constitute the attitude detection photoelectric sensor group 3. As shown in the figure, for example, in order to detect the left and right movements of the athlete's competition posture, two positions are placed on both shoulders.
Two sensors 31 and 32 are provided, and a sensor 33 is provided at the center of the back to detect the forward and backward movements of the athlete.
Also in this case, some viewpoints are determined and set in advance. For example, if the posture of the athlete leans to the right and the amount of light detected by the sensor 32 on the left increases, the viewpoint is set so that the displayed image also leans to the right. The viewpoint is set so that the position of the horizontal line displayed slides upward on the screen when the detected light amount increases. As a result, the video changes from a viewpoint suitable for the competition posture of the competitor. In this case also, the movement from one viewpoint to another viewpoint is performed smoothly.

FIG. 6 is a flow chart showing the processing procedure in the image processing and arithmetic processing base 1 at that time.
Therefore, first, it is determined whether or not the posture detecting photoelectric sensor group 3 has operated (step S61), and when it is determined that the attitude detecting photoelectric sensor group 3 has operated, the viewpoint data is changed to the viewpoint data corresponding to the operating condition (step S62). . On the other hand, if it has not been activated, the flow proceeds to step S63. Step S
In 63, it is determined whether or not the current camera position and the camera position based on the viewpoint data match. If it is determined that they do not match, the camera position is brought closer to the position based on the viewpoint data ( Step S64).

Incidentally, the position of the sensor is not limited to the above-mentioned form, and various kinds can be considered according to the type of game.

Incidentally, regarding the relationship between the concept of the viewpoint of the present invention and the driving operation, for example, the following two modes may be provided. That is, one is a "viewpoint of watching the game outside" mode, and the other is a "driver's viewpoint" mode. In the former case, the visual direction does not change even if the vehicle spins, and in the latter case, the visual direction changes accordingly due to the spin or the like. In the example of the viewpoints shown in FIGS. 3 and 4, it is clear that the viewpoint 4 is set to the “game external viewpoint” mode, and the viewpoint 2 is set to the “driver's viewpoint” mode. .

The above is the description of the embodiment of the present invention.
Regarding the case of using the viewpoint changing switch 2 and the case of using the posture detecting photoelectric sensor group 3, both may be used in combination, or one of them may be used alone. When merging, either one may be preferentially processed.

Although the so-called driving game has been described in this embodiment, it is obvious that the present invention is not limited to this and that it can be applied to all other games. Further, this electronic amusement device can be applied to commercial ones such as game arcades and general household ones, and in any case, the arithmetic means (arithmetic processing board) can be used as shown in FIG.
Alternatively, it is obvious that the procedure for executing the flowchart of FIG. 6 is stored in the storage medium.
