In an image encoding / decoding device of the present invention, the prediction direction in a target block, i.e., a block which becomes the target of the intra-frame prediction processing, is estimated by taking advantage of pre-encoded blocks which are adjacent to the target block. First, as edge information on decoded images on the adjacent blocks, intensities and angles of the edges are calculated. Next, of the degrees of likelihood calculated with respect to each prediction direction by taking advantage of this edge information and, e.g., a neural network, the prediction direction whose degree of likelihood is the highest is employed as the prediction direction in the target block. Also, a variable-length code table is dynamically created based on the estimated result, which allows a significant reduction in the prediction-direction representing code amount.
