Title:
WIRELESS STEREOSCOPIC GLASSES SYSTEM
Document Type and Number:
Japanese Patent JPS6417590
Kind Code:
A
Abstract:
PURPOSE:To eliminate the shift in switching a display and to attain digital IS by generating a switching signal for a liquid crystal shutter from an analysing/composing signal. CONSTITUTION:In the coding circuit 1 of a transmission part, a single-pulse/ double-pulse coding signal is generated in synchronizing with the switching of a display screen, the signal is modulated, and is transmitted as an optical signal by an infrared light emitting diode LED. In the light receiving and amplifier circuit 13 of a light receiving part, the signal is smoothened after being subjected to a band-pass filter, and an output signal from the circuit 13 is analyzed and composed, according to the result, when the coding signal of a frame is detected, the liquid crystal shutter 16 is switched synchronizing with the detection.
