Embodiment Construction

[0024] The best way to practice the invention

[0025] figure 1 A preferred embodiment of the system for controlling shutter glasses according to the invention is shown. A stereoscopic input video signal 103 is received by a display unit 101, eg an LCD display. A left eye / right eye (L / R) selection signal may be included within the stereoscopic video signal 103 or may be transmitted as a separate L / R selection signal 102 . Most display units 101 contain a number of signal processing blocks 104 for adapting the signal for display 105 to meet user needs, eg buffering, interpolation, refresh rate and quality enhancement eg brightness and contrast control or signal sharpening. These signal processing blocks 104 introduce a delay for each frame to be displayed which typically depends on the frame content, ie the amount, content and complexity of the data to be processed. Thus, each frame to be displayed 105 is delayed by a different television device by an amount of time relative...

Abstract

A method for controlling shutter glasses in synchronization with a video signal, comprising the steps of receiving a shutter glasses driving signal, the signal indicating the opening and closing time of shutter glasses, receiving a L / R side selection signal, the signal indicating the left or the right eye for which the a video frame of the video signal is displayed, opening or closing the left of right shutter glass according to the value of shutter glasses driving signal and the L / R side selection signal, wherein the method further comprises the steps of monitoring a screen programming signal at a display unit on which the video signal is to be displayed and processing the screen programming signal to generate the shutter glasses driving signal.

Description

technical field [0001] The present invention relates to a system and method for controlling shutter glasses for viewing stereoscopic images. Background technique [0002] The most common type of shutter glasses are liquid crystal (LCD) shutter glasses. The left and right lenses are alternately darkened synchronously with the display of the frames for the left and right eyes on the external display. When this operation is repeated at a high frequency, ie above 50 Hz, a three-dimensional experience will be created for the user. [0003] A common problem with shutter glasses is proper timing synchronization between the darkening of the lenses and the display of the frame on the external monitor. [0004] U.S. Patent No. 5,796,373 discloses a computerized stereoscopic image system, which includes LCD shutter glasses, a VGA card for generating analog RGB signals, a monitor for displaying analog RGB signals, and a shutter synchronizer. card's signal and generate the signal that...
