Description of the Related Art Conventionally, there is known a shooting game apparatus in which a player uses a light gun or the like to shoot a target displayed on a screen of a display device or the like. In such a shooting game device, as a method of setting the aiming position (landing position) on the screen, there are a light emitting type and a fixed coordinate type. The light-emitting type temporarily illuminates the screen of the display device,
The position on the screen at which the muzzle is directed is set as the aiming position according to the scanning timing when the light is provided on the gun and detected by the sensor. In the fixed coordinate type, the gun is fixed to a part of the housing of the game device, the direction of the gun can be changed around this fixed position, and the aiming position is detected by detecting the direction of the barrel portion. Set. By setting the aiming position by these methods, it is possible to determine whether or not a bullet or the like fired from a gun operated by the player hits a target displayed on the screen of the display device.

[0003]

However, in the above-mentioned conventional shooting game device, the player always uses a shooting device such as a dedicated handgun fixed directly to a housing or the like or connected via a cable. There must be. Therefore, for example, a child who cannot handle well due to a heavy shooting device may not be able to enjoy the game sufficiently. Also, in order to send a firing instruction from the shooting device to the game device body when the player triggers the shooting device, the shooting device and the game device body are usually connected with a cable, so this cable is connected during the game. There is a case where the operation of the player is restricted by being in the way. Furthermore, if the shooting device is provided with a light receiving unit or the like, it is relatively expensive, but since it is frequently handled by the player, it is more likely to break down than other parts of the shooting game device, and the replacement frequency is low. There is also a problem that the cost increases accordingly.

[0004] The present invention has been made in view of the above points, and it is an object of the present invention to enable anyone to easily enjoy the game, increase the degree of freedom of the player's operation, and reduce the cost. An object of the present invention is to provide a shooting game device capable of reducing the cost.

In order to solve the above-mentioned problems, a shooting game apparatus according to the present invention detects a player's posture photographed by photographing means by posture detecting means, and detects the detected player's posture. The aiming position included in the game screen is set in accordance with the setting, and the aiming position can be set without the player using a shooting device such as a dedicated handgun, which is conventionally provided in the game device. Children who could not handle well because of the heavy shooting device can easily enjoy the shooting game. Further, since there is no need to connect the shooting device and the game device main body with a cable, it is possible to increase the degree of freedom of the player's operation. Further, since there is no need to replace the shooting device, it is possible to reduce costs.

In particular, while photographing the player's hand simulating the shape of a shooting device, the position and direction of a finger corresponding to a barrel portion are detected, and the position and direction of the finger are detected.
It is desirable to set the position where the extension line of the finger and the screen intersect as the aiming position. Since the player can play the game with his / her own hand as a pistol, there is no need to use a special shooting device. Further, it is possible to easily set the aiming position based on the position and the direction of the finger.

[0007] In addition, while shooting the shooting device possessed by the player, the position and direction of the barrel of the shooting device may be detected to set the aiming position included in the game screen. The player can enjoy the game using a familiar model pistol or the like. In addition, since a dedicated shooting device including a light receiving unit and the like is not required, manufacturing costs and costs required for replacement are not required.

When photographing a player, it is desirable to photograph from a plurality of directions, whereby the position and direction of the finger corresponding to the barrel of the hand of the player simulating the shape of the shooting device, and the possession of the player It is possible to accurately detect the position and direction of the barrel portion of the shooting device to be performed.

It is preferable that the apparatus further comprises first firing instruction means for issuing an instruction to fire a bullet when a predetermined operation is performed by the player. By performing a predetermined operation by the player, it is possible to issue a bullet firing instruction at an arbitrary timing. In particular, by configuring the first firing instruction means including a pedal provided at the lower part of the housing of the game device, the player can instruct the firing timing of the bullet simply by depressing the pedal, and the firing can be performed. The operation of instructing becomes easy.

[0010] Further, a second bulletinstructing means may issue a bulletinjection instruction according to a predetermined sound emitted by the player. In this case, the player can issue a bullet firing instruction without performing any special operation, so that the limbs and the like can be used freely, and restrictions on the player's operation can be reduced. In particular, if an instruction to fire a bullet is issued in accordance with the result of performing the voice recognition processing on the sound collected by the microphone, an accurate firing instruction in response to only a specific sound of the player can be made.

Further, a third bulletinstructing means may issue a bulletinjection instruction according to a predetermined operation by the player. Since the rules of the game need only be determined assuming that a bullet is fired when the player performs a specific action, there is no need to provide a special configuration to issue a bullet firing instruction, and the configuration can be simplified. Will be possible. In particular, it is desirable that the movement of the player is detected based on the posture detected at regular intervals by the above-described posture detection means. In this case, since it is not necessary to add a special configuration for detecting the operation of the player, the configuration can be further simplified.

It is desirable that the above-mentioned photographing means be realized using an artificial retinal chip. In general, an artificial retinal chip includes a part for imaging and a part for performing various image processing such as edge detection in one chip, so that the configuration can be simplified and the processing speed can be increased.
