Stereoscopic television system
Abstract
Abstract PURPOSE: To eliminate a flicker phenomenon from the eyes, by elavating the display switching frequency by integer m times as high as the conventional value for the left and right pictures and at the same time reducing the time during which the left and right pictures are united to see the object stereoscopically to 1/m compared with the conventional time. CONSTITUTION: The sweep frequencies of vertical and horizontal deflecting circuits 50 and 60 are set at a level of integer m times as much as the conventional value through a timing circuit 130, and at the same time trigger signals PS' and R/W signal having the same cycle as a discriminating signal PS are sent to a signal distributor 90 and field memories -100 and 110 corresponding to the left and right pictures. On the other hand, a trigger signal PD having a cycle of 1/m times as much as the pickup cycle is sent to a signal selector 120 and a stereoscopic glasses device 80. In such way, the same picture is displayed on a display device 40, m times repetitively and in a 1/m-times cycle. Accordingly the left and right pictures are united to see the object stereoscopically through the device 80 and within a double time compared with the display cycle of the device 40.
