Abstract
A device for coding a decoded image is provided. The device performs a process of categorizing respective pixels into a plurality of types on the basis of pixel values of the decoded image, calculating a correction value for a pixel for each of the types, and correcting the pixel value of the decoded image on the basis of the correction value on the decoded image obtained by performing decoding after coding an original image, the respective types are further categorized into an edge group in which an edge direction of the original image and an edge direction of the decoded image are the same and into a noise group in which an edge direction of the original image and the edge direction of the decoded image are different, a higher priority is given so that a correction amount for the noise group becomes greater, and the correction value is calculated.
