摘要： A decoding apparatus is provided which can perform error concealment accurately by reducing false detection of an error and detecting an error efficiently. The decoding apparatus (100) which decodes a coded image coded on a per-block basis, includes: a variable length decoding unit (101) that decodes a coded image; an error occurrence position detection unit (109) that determines a candidate block on which an error has possibly occurred, by using a quantization parameter which is obtained for each block and which is resulting from the decoding by the variable length decoding unit (101); and an error correction unit (110) that corrects blocks including and following the candidate block determined by the error occurrence position detection unit (109).

摘要： An image memory access control unit (502) judges whether or not an additional pixel required for motion compensation is necessary, the additional pixel not being included in a plurality of pixels forming an image shown by a reference block. When the additional pixel is judged to be necessary, a yet-to-be-obtained-pixel interpolating unit (503) generates at least one additional pixel, and generates a reference image to be used for motion compensation using the generated at least one additional pixel and at least a part of the image shown by the reference block. When the additional pixel is judged to be unnecessary, the yet-to-be-obtained-pixel interpolating unit (503) outputs at least a part of the image shown by the reference block as the reference image.
