ABSTRACT:
A shutter synchronization circuit for a stereoscopic system, which comprises a CPU, a main memory, a VGA graphic card, a monitor, a RS 232 interface circuit, an interrupt controller, a timer and an external shutter synchronizer with RS 232 interface; the circuit is to be used in personal computers; by using the RS 232 interface and the external shutter synchronizer with RS 232 interface, the switching of the LCD shutter and the vertical synchronization scanning signal of the VGA graphic card can be in synchronization. By using a hardware system of a stereoscopic image, a user can see a stereoscopic scene instead of a plane image.
