Patent ID: 8315467

Claim:
An image encoding device which can encode a difference between original image data and predictive image data, and create the predictive image data based on local decode image data obtained by decode of encoded data, comprising: an intra prediction module operated to create the predictive image data by means of intra prediction in blocks of pixels resulting from division of a frame of image data; and a pseudo-local-decode-image-creation module operated to more simply encode and decode original image data in comparison to creation of the local decode image data, wherein the intra prediction module has a mode select module for selecting an intra prediction mode, and a predictive data creation module for creating the predictive image data by means of intra prediction according to the operation mode selected by the mode select module, and the mode select module can use pseudo local decode image data created by the pseudo-local-decode-image-creation module to select an intra prediction mode.
