Abstract

An image data decoding device includes a determination unit, a first pixel value generating unit, and a second pixel value generating unit. The determination unit receives compressed image data including information of one DC component, information of frequency components and a block end code for each block of an image as a result of frequency analysis and determines whether the block consists of the DC component and the block end code. The first pixel value generating unit performs inverse operation to the frequency analysis to generate pixel values of the block when the block is determined as not consisting of the DC component and the block end code. The second pixel value generating unit generates one and the same pixel value for all pixels of each block based on information of the DC component when the block is determined as consisting of the DC component and block end code.
