Abstract
An exemplary video processing method for processing a plurality of input frames includes storing the input frames successively, performing a frame rate conversion upon the successively stored input frames by utilizing a frame rate conversion circuit, and performing a predetermined data processing operation upon an output of the frame rate conversion. The step of performing the frame rate conversion includes generating and outputting a plurality of first output frames concurrently by referring to image data of at least one input frame. The step of performing the predetermined data processing operation includes receiving image data of the first output frames concurrently, wherein the first output frames contain image data of temporally adjacent output frames required by the predetermined data processing operation; and performing the predetermined data processing operation upon the image data of the concurrently received first output frames.
