PURPOSE:To display a two-dimension picture or a three-dimension picture without causing flicker by providing two video signal input terminals, two signal processing means and two display means observed by a right eye only and a left eye only, sending a right eye use video image to the display means for the right eye and sending a left eye use video image to the display means for the left eye. CONSTITUTION:When switch circuits 2R, 2L are turned to the position of (a), a video signal inputted from a video signal input terminal 1R is inputted to a Y/C separation circuit 3R and a synchronizing separator circuit 7R through a switch circuit 2R, the video signal is separated into a Y signal and a C signal at the Y/C separation circuit 3R and fed to a display device 6R via a decoder 4R and a signal processing circuit 5R. Furthermore, a synchronizing separator circuit 7R separates a synchronizing signal to control a drive frequency of a drive circuit 9R. The similar processing is implemented in the system of suffix L. In this case, the display device 6R is arranged at a position observed by the right eye only and the display device 6L is arranged at a position observed by the left eye only. |
