Abstract

PURPOSE:To judge the left and right opening/closing states of a shutter spectacles automatically for a left and a right image by providing a means for switching the left and right parts of a liquid crystal spectacles in synchronism with the status of the status register of a graphic processor and a driving device for the liquid crystal spectacles. CONSTITUTION:Data on the left and right images are read in two VRAMs (memory 6) respectively and the shutter spectacles driving device 2 is initialized so as to synchronize the left and right parts of the shutter spectacles 3 with the left and right images. Then, the status of the status register 8 in the graphic processor is detected and when scanning is not in process, a bank is switched to a VRAM which is not in a display state between the two VRAMS, thereby performing the left- right switching of the shutter of the liquid crystal shutter spectacles 3. Consequently, it is judged automatically which of left and right shutters of the shutter spectacles is opened for the display of the left and right images.

、これに同期させて液晶シャッタメガネを駆動させる。(B) Prior art] The time-division method for stereoscopic viewing of computer data involves displaying right-eye and left-eye images alternately on a monitor, synchronizing them with this, and using liquid crystal shutter glasses to display right-eye and left-eye shutters. Conventionally, in order to detect the switching of the display between the right and left eyes on the monitor, the vertical synchronization signal of the monitor was used, and the liquid crystal shutter glasses were driven in synchronization with this signal.

要があり不適確である。(C) Problems to be Solved by the Invention In the conventional system that uses a vertical synchronization signal for synchronization, it is difficult for the human eye to judge whether to open the right side or the left side of the shutter glasses for the right or left image. It is necessary to make a judgment based on this and change the settings using a switch or the like. Furthermore, when viewing normal images without stereoscopic viewing, the liquid crystal shutter glasses remain activated. Furthermore, in personal computers that do not have independent terminals for vertical synchronization signals, it is necessary to newly extract the vertical synchronization signals from the computer itself or from the monitor, which is inappropriate.
