Title:
画像処理装置及び画像処理方法
Document Type and Number:
Japanese Patent JP5285683
Kind Code:
B2
Abstract:
There is provided an image processing device that reduces influence by a compressibility error of image data generated by a previous frame on output image data. The image processing device generates a compressibility error prediction value ERR, based on an input image data DI, generates substitute image data DIA of the input image data DI, based on an emergence tendency of the compressibility error, selects the input image data DI or the substitute image data DIA, based on the compressibility error prediction value ERR to set a result as current image data DC, generates next state image data DP, based on the current image data DC and state image data DR, compresses the next state image data DP to generate compressed state image data DPC, stores the compressed state image data in a frame memory 18, generates the state image data DR by reading the compressed state image data DPC from the frame memory 18 and decompressing the same, and generates output image data DQ, based on the current image data DC and the state image data DR.
