Abstract
A decoding apparatus includes a standard predicted image generating unit which generates a standard decoded image and a standard predicted image of standard image quality; a non-standard decoded image generating unit which generates a non-standard decoded image different in image quality based on a prediction error information; a non-standard predicted image generating unit which generates a non-standard predicted image different in image quality based on the non-standard decoded image; and a correction value calculating unit which calculates correction values corresponding to differences between the standard and non-standard predicted images. The non-standard decoded image generating unit includes a predicted image reconstructing unit which corrects the non-standard predicted image, and a decoding unit which inverse-quantizes the prediction error information and adds the inverse-quantized prediction error information and the corrected non-standard predicted image to generate the non-standard decoded image.
