摘要：
An image processing apparatus is disclosed. The image processing apparatus includes a coefficient correction unit for correcting only a high frequency coefficient situated adjacent to a tile boundary of an encoded image data divided into non-overlapping tiles. The high frequency coefficient is corrected during a process of decoding the encoded image data.
