TWI232769B - Visual feedback system for light gun - Google Patents

Abstract

This invention provides a visual feedback system that placed between the game engine system and the light gun. It collects the light spot signal or light spot coordinate data, and then transmits to game engine system from a light gun. If light spot signal is obtained, the control circuit uses H-sync and V-sync of the video frequency signal to calculate and obtain the light spot coordinate data of the light gun. The light spot coordinate data is transmitted to the image synthesis circuit, to set the cursor of the aiming spot of light gun to the position of the corresponding aiming point on the screen. Therefore, it synthesizes with the image signal transmitted from the game engine output to the monitor.

丄 232769 V. Description of the invention The game is not played with a stack of bombs at a time. (2) The player ’s technology is in the light equipment adjustment equipment. This point also has the photographer's limitation. This game can be used to point to the system and cannot be used. When someone places it, it will have the same function as the color point. The soft purpose of the game does not produce a cursor type that switches the light to the aim point. . In addition, a laser light is directly installed on the light grab. When playing on the screen, a red light spot will appear, and then the red light point adjustment and the light aiming point will be focused on which position on the screen. position. Therefore, the conventional light gun device itself is also unable to actively provide a visual feedback effect and is a practical design mode. Provides a visual feedback effect of the light gun aiming point in the light gun game software, especially for the cursor of the light gun aiming point. The other purpose is to provide an unrestricted light gun game software. 3. The cursor type of the light-seeking Miao punctual point can be selected to produce a variety of light gun aiming point cursor type visual feedback systems. [Summary of the Invention] There is iron in the conventional technology that cannot be generated by the light grab itself to show the light grab target. The cursor provides a visual feedback system installed between the game host system and the light gun, and the game host The system can be a TV amusement host or a computer game system. The visual feedback system is used to capture a light point signal or light point coordinate data transmitted from a light grab to the game host system. If a light point signal is obtained, the control circuit Then use the horizontal synchronization signal (H_sync) and vertical synchronization signal (v_sync) generated by the synchronization separation circuit to calculate the light spot coordinate data of the light grab, and then send the light spot coordinate data to the image synthesis
