ABSTRACT:
A graphic display unit makes it possible for a stereo display or blink operation to be implemented on a window system with each window having an arbitrary contour, and on a window by window basis. The graphic display unit of this invention comprises a frame buffer for a right eye, a frame buffer for a left eye, a window-id buffer which stores a window-id corresponding to the contour and position of windows on the frame buffer, a look-up table which stores control information related to stereo display and is accessed based on a window-id, a frame counter that issues the timing of switching frame buffers, a stereo display control circuit for switching buffers based on signals from both the look-up table and from the frame counter, and stereo viewer that controls shutters for a right eye and a left eye.
