APPARATUS FOR ENCODING AND DECODING IMAGE BY USING SKIP ENCODING AND METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for encoding and decoding an image signal by using skip encoding, and to provide an apparatus thereof.SOLUTION: In execution of intra-prediction, an image encoding method by using skip encoding comprises the steps of: performing a filtering operation on a reconstructed signal which is reconstructed prior to an encoding object signal in an encoding object image; generating a prediction signal for the encoding object signal by using the filtered reconstructed signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding a residual signal which can be generated on the basis of difference between the encoding object signal and the prediction signal, thereby performing the skip encoding on the encoding object signal.SELECTED DRAWING: Figure 1
