ABSTRACT:
In a shooting game machine, a projector projects a shooting video image, in which a target appears, on a screen. A player may fire a laser gun to emit a light beam to the target on the screen. A video camera photographs the screen, irrespective of any display scanning of the projector, and outputs its picture signal to coordinate computing means. The coordinate computing means counts clock pulses, which are output from a pulse generator, during a period from when a vertical synchronous signal of the picture signal is output until a beam point signal is output, and divides the count value by a predetermined reference pulse number to compute and output the X coordinate and the Y coordinate of the beam point on the screen.
