ABSTRACT:
An image processing system for processing a video signal includes an encoder and a decoder, wherein the encoder comprises a frame decimator for selecting a plurality of frames from the video signal, a unit for creating M number of candidate frames for each of the non-selected frames, i.e., skipped frames by using M number of skipped frame prediction factors, and a unit for comparing each of the N skipped frames with each of the candidate frames to transmit a skipped frame prediction factor for each of the N skipped frames to the decoder; and the decoder comprises a unit for deciding each of the N skipped frames between the previous frame and the reconstructed current frame by using the transmitted skipped frame prediction factor.
