Abstract
The display device image stabilization apparatus is utilized in a display system having a frame buffer coupled to a display device. The apparatus includes a sampling arrangement coupled to the frame buffer for sampling input video data to generate a display signal, wherein the display signal is stored temporarily in the frame buffer as buffer information. A control device is coupled to the frame buffer for comparing the buffer information with reference information to determine whether the buffer information and the reference information are similar to one another. The control device generates a gain adjustment signal when the buffer information and the reference information are different from one another. Coupled between the control device and the sampling arrangement is a phase lock loop circuit for varying the display signal in response to the gain adjustment signal. The buffer information is updated continuously until it is substantially similar to the reference information, and the display image has been stabilized.
