Abstract
An image encoding device includes a dynamic range generator for outputting dynamic range data Ddof block image data Dc, an average value generator for outputting average value data Deof the block image data Dc, a number-of-pixel reducing unitfor decreasing number of pixels of the block image data by reduction-number of pixels to generate reduced-number-of-pixel block image data Dc', an encoding parameter generatorfor generating encoding parameter paspecifying a quantization bit rate and the reduction-number of pixels in accordance with the dynamic range data Dd, a quantization threshold generatorfor generating a quantization threshold value tb, and an image data quantizerfor generating quantized image data Dffrom the reduced-number-of-pixel block image data Dc′ with use of the quantization threshold value tb
