ABSTRACT:
Disclosed are an image coding method and apparatus for coding digital image data in a highly efficient manner, and to an image decoding method and apparatus for decoding the data thus coded. Each image signal constituting the image data is partitioned into a plurality of pixel blocks, and coding of each of the image signals is performed in block units. A plurality of items of coded data obtained by such coding are gathered together to form a block (a re-sync block) corresponding to each image signal. A plurality of the re-sync blocks corresponding to the image signals of an image area of the original image data are sequentially combined, boundary-line information is inserted between mutually adjacent re-sync blocks, and an error correction code is attached to form a code for transmission. In the apparatus for receiving this code, the code is decoded into the original image data by partitioning the code into re-sync blocks and performing decoding and interpolation in re-sync block units.
