Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract: An inter-view frame reference method in multi-view moving picture coding and an apparatus therefor are provided to reduce a residual signal and enhance a compression rate by referring to a frame of a different viewpoint of the same time or a frame of a different viewpoint of a different time when multi-view moving picture data are encoded. A multi-view GOP(Group Of Picture) arranging unit(110) includes GOPs corresponding to at least one or more viewpoints, and arranges the respective view points between the respective GOPs to have the same coding structure. A mutual viewpoint reference unit(120) refers in the picture order within a spatially close viewpoint among pictures of different viewpoints previously encoded in the respective GOPs.
