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 in particular, it retains information relating to a display object as three-dimensional stereoscopic data, and performs 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, display image information on a display device is two-dimensional plane information,
The so-called pictures were continuously projected to create a dynamic continuous image. According to this conventional display method, all objects drawn are based 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. By introducing a concept of a viewpoint (a position where the camera is located), if a certain point on the three-dimensional coordinate axis is defined as a viewpoint, an image of the target object viewed from that position will be displayed on the 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, camera work which does not actually exist can be realized by introducing the concept of viewpoint. With the concept of viewpoint, it becomes possible to realize an image with a light source 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 was fixed from the viewpoint of the athlete. Even with an electronic game machine having a plurality of such viewpoints, changing the viewpoint is intended by the programmer at the time of creating the game program and is fixed at the time of creating the program. Is never reflected. Furthermore, changes between multiple viewpoints were also gradual. Therefore, if the above-mentioned three-dimensional space display technology is adopted in an electronic game machine, it is possible to display an image from any viewpoint of the three-dimensional space related to the displayed image information.

The present invention has been made under the circumstances 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.

[0007]

According to the present invention, information relating to a display target is held as three-dimensional stereoscopic data, and a three-dimensional calculation process is performed on the information so that the display target can be viewed from all viewpoints. The present invention relates to an electronic amusement machine that can be visualized as an object, and an object of the present invention is to hold information related to a display object as three-dimensional stereoscopic data and perform a three-dimensional arithmetic processing on the information. In an electronic amusement machine having a processing means and a display means for performing a display based on the information relating to the display object which is arithmetically processed by the arithmetic processing means, information on one or a plurality of viewpoints is set in advance, and the game is played. A switching means operated by a person is provided, and the arithmetic processing means selects one of the viewpoint information based on a signal from the switching means, and selects one of the viewpoint information. It is achieved by displaying the display object on the display means based on the viewpoint.

Further, information on one or a plurality of viewpoints is set, detection means for detecting the competition posture of the athlete is provided, and the arithmetic processing means calculates the viewpoint based on the signal from the detection means. This is achieved by selecting one of the pieces of information and displaying the display target on the display means based on the selected viewpoint.

[0009]

According to the present invention, information on one or a plurality of viewpoints is stored in an electronic game machine which can hold information related to a display object as three-dimensional stereoscopic data and can be visualized as a three-dimensional stereoscopic image by a three-dimensional arithmetic processing. Is set, and switching means operated by the athlete or detection means for detecting the competition posture of the athlete is provided, and one of the viewpoint information is selected based on a signal from the switching means or the detection means. Therefore, the viewpoint when displaying the display target on the display means changes according to the operation of the athlete or the competition posture of the athlete.

[0010]

Embodiments of the present invention will now be described in detail with reference to the drawings. By the way, according to the present invention, as described above, the information about the display target is held as three-dimensional stereoscopic data, and the three-dimensional arithmetic processing is performed on the information, so that the display target can be viewed from all viewpoints. It is about an electronic game machine that can be visualized as.

FIG. 1 is a block diagram showing the configuration of an embodiment of an electronic game machine according to 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. A sensor group 3 is provided. In either case, the output signal is input to the image processing and arithmetic processing board 1.

First, the case of using the viewpoint changing switch 2 will be described. That is, the viewpoint of the display image is changed based on the intention 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, the viewpoint is "slightly behind the vehicle", the viewpoint is "the competitor (driver) 's viewpoint", the viewpoint is "low altitude behind the own vehicle, the viewpoint is" the own vehicle ". Behind the high sky. ”The setting to the device is performed by giving the specific three-dimensional coordinates of those viewpoints. Therefore, in the case of this viewpoint changing switch 2, for example, it is sequentially switched each time it is pressed. That is, viewpoint → viewpoint → viewpoint → viewpoint → viewpoint.At this time, moving from one viewpoint to the next viewpoint is performed while processing the 3D data and gradually moving the viewpoint. It is done continuously in several ways.

FIG. 2 is a flow chart showing a processing procedure in the image processing and arithmetic processing board 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 moved 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 may 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, and the athlete leans forward to bend the sensor 33. 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 image changes in accordance with the competition posture of the athlete, from the viewpoint that matches the situation. In this case also, the movement from one viewpoint to another viewpoint is performed smoothly.

FIG. 6 is a flowchart showing a processing procedure in the image processing and arithmetic processing board 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 does not operate, the process directly 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.

By the way, regarding the relationship between the concept 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 is set to the “game external viewpoint” mode and the viewpoint 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 they are used in combination, 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 can be applied to all other games. Further, it can be applied to commercial ones such as game arcades and general household ones.

[0022]

As described above, according to the electronic play apparatus of the present invention, the viewpoint at the time of displaying on the display means can be changed according to the intention of the competitor and the competitive posture of the competitor.
You can enjoy a realistic game with a wide range of operation modes.
