IMAGE PROCESSING APPARATUS AND METHOD

The present disclosure relates to image processing apparatus and method that can suppress a reduction in image quality. An addition order of candidate data that is a candidate for additional data to be added to encoded data including encoded image data in blocks is set on a block-by-block basis in order to set the encoded data to a fixed length. In this case, pseudo-random numbers may be used to set the addition order of the candidate data, or table information indicating the addition order of the candidate data may be used to set the addition order of the candidate data. The present disclosure can be applied to, for example, an image processing apparatus, an image encoding apparatus, an image decoding apparatus, or the like.
