Abstract: A synchronous image-switching device and switching method thereof are provided. The synchronous image-switching device comprises an image filter for generating target image data according to the frequency of a first clocking signal, a buffer for holding the target image and an image output control device for outputting the target image according to the frequency of a second clocking signal. Because the synchronous switching device of the present invention allows the clocking frequency of the source image to be different from that of the target image, images can be switched synchronously and power consumption of the switching operation can be reduced.

Abstract: An image processing method is provided. According to the present method, the formulas of the prediction modes of a 4*4 block in intra frame prediction are expanded and applied to 4*4 blocks or 8*8 blocks in a 16*16 block. The prediction modes of the 4*4 blocks or 8*8 blocks in the 16*16 block are determined within one pass, or the prediction modes of the 8*8 blocks in the 16*16 block are determined within three passes. Accordingly, the operation of determining the prediction mode of each 4*4 block is saved, and the time for processing intra frame prediction of the 4*4 blocks is effectively reduced. Eventually, the efficiency of image processing is improved.
