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.
