PURPOSE:To simplify the structure of a shooting game apparatus by detecting a hitting position without synchronizing a projector with imaging means when an optical beam is projected from shooting means toward a predetermined target displayed on a screen by using the projector to play a shooting game. CONSTITUTION:A video picture for shooting is projected from a projector 28 toward a screen 10, and a player shoots an optical beam toward a target of the screen 10 by using a laser gun 14. The screen 10 is projected by a video camera 30, its video signal is input to an arithmetic circuit 42 through a waveform shaper 36 and a counter 38, and the circuit 42 calculates a beam point (X, coordinates of the beam on the screen 10. Then, an on-target judging circuit 46 collates the calculated result of the beam point coordinates with a target display position to decide an on-target of the beam. In the case of the on-target, a hitting image, etc., is displayed on the screen 10 through the projector 28. |
