Visual feedback system for optical guns

Abstract

The invention provides a visual feedback system installed between a game host system and an optical gun. It is used to extract a bullet falling point signal or bullet coordinate signal sent from the optical gun to the game host. If the extracted signal is a bullet falling point signal, a control circuit then uses the horizontal synchronous signal H_sync and the vertical synchronous signal V_sync of the video frequency signal to compute the coordinates of the bullet. The coordinate data are sent to an image synthesis circuit, which combines an aiming point cursor on the corresponding coordinate data with the video signal transmitted from the game host and outputs the synthesized image on the display screen.
