Disclosed are an image encoding method, an image decoding method, an image data processing method and apparatus therefor. The image encoding method of the present invention comprises: determining in a current inter-frame encoding frame a current intra-frame encoding block using a limited intra-frame prediction mode; determining that an adjacent encoding block adjacent to the current intra-frame encoding block comprises an adjacent inter-frame encoding block; updating, on the basis of a fixed value or of the image data in an adjacent intra-frame encoding block comprised in the adjacent encoding block, the image data in the adjacent inter-frame encoding block; and encoding, on the basis of the updated image data in the adjacent inter-frame encoding block, the current intra-frame encoding block. The image encoding apparatus according to the present invention comprises a first determination module, a second determination module, an update module, and an encoding module. The method and apparatus according to the present invention can be used to enhance the error recovery capability of intra-frame encoding blocks and improve the decoding quality of image data. |
