Abstract
Block representative values are set adaptively based on the feature amount concerning the distribution state of a prepared histogram of input image data. Thus, if block truncation coding is executed based on an input image having mixed CG image and scanned image areas, efficient coding can be performed and a high-quality decomposed image can be provided. Further, when the histogram is divided into image data groups, the image data groups can be again divided to provide a high-quality decomposed image, thus efficient coding can be performed and a high-quality decomposed image can be provided more reliably.
