Patent ID: 8493298

Claim:
A video display system comprising: an image processing unit receives continuously an input video signal including input frame signals for generating an output video signal including output frame signals having a higher frame rate than the input frame signals; a display unit for displaying a video image in accordance with the output frame signals, wherein each of the input frame signals has 2^M gray scale levels for each pixel; the image processing unit further generates the output frame signals including at least a first output frame signal having 2^N gray scale levels with N<M for each pixel and a second output frame signal having [2^M-2^N] or fewer gray scale levels for each pixel wherein M and N are positive integers; and the image processing unit further generates the first output frame signal includes a first gray scale data having a same number of gray scale levels as a second gray scale data of the second output frame signal and the first output frame signal and second output frame signal having different output frame period.
