Abstract

A video processing method for a video processing circuit includes receiving a first video source corresponding to a first pixel rate and a second video source corresponding to a second pixel rate, wherein a processing data rate of a video processing path is greater than or equal to a sum of the first pixel rate and the second pixel rate. The method further includes using the processing data rate to sequentially perform an image processing to a first image of the first video source and a second image of the second video source corresponding to the same display time, to generate a first processed image and a second processed image.
