摘要

1. A prediction image encoding device that divides an image into a plurality of regions, generates an intra-frame prediction signal with respect to a pixel signal contained in a target region that is a processing target among regions, and encodes a difference signal between the pixel signal of the target region and the intra-frame prediction signal, moreover, the device for encoding images with prediction contains:! means for determining the first prediction method, which, based on the processed data corresponding to adjacent regions containing the reconstructed pixel signals and adjacent to the target region, obtains a prediction method that generates an intra-frame prediction signal having strong correlation with pixel signals of adjacent regions from a predetermined set prediction methods for generating an intra-frame prediction signal and determines a prediction method as a first prediction method; ! prediction signal generating means that generates an intra-frame prediction signal based on a first prediction method determined by means of determining a first prediction method; and! image encoding means that encodes a difference signal of a pixel signal of a target region based on an intra prediction signal generated by the prediction signal generating means. ! 2. A device for encoding predictive images, which divides an image into multiple regions, generates an intra-frame prediction signal for a signal of pixels containing
