This invention has as its object to provide an image coding method which can efficiently encode image data by fully utilizing a two-dimensional correlation of an image. A block matching means searches for a block position corresponding to a minimum absolute value sum of differences of a pixel block to be encoded from already encoded pixel blocks. The searched block position information is encoded by an encoder, and the searched inter-block difference value is Huffman-encoded by another encoder. A code generator generates encoded data using these codes.
