Abstract:
1. An image processing apparatus comprising: an inverse quantization section configured to carry out an inverse quantization process on compressed image information obtained as a result of a quantization process performed after an orthogonal transform process executed in block units; an inverse orthogonal transform section configured to carry out an inverse orthogonal transform process on coefficient data obtained as a result of said inverse quantization process in order to output decoded image data; a motion-vector prediction section configured to (1) carry out a hybrid motion-vector prediction process on the basis of a result of a motion-vector decoding process executed by performing a variable-length decoding process, (2) generate motion-vector data obtained as a result of said hybrid motion-vector prediction process, and (3) embed hybrid prediction information to be used to indicate whether or not it is necessary to carry out a deblocking process into said motion-vector data so as to allow the result of said hybrid motion-vector prediction process to be reutilized at said deblocking process; a motion compensation section configured to carry out a motion compensation process for said decoded image data output by said inverse orthogonal transform section by making use of said motion-vector data received from said motion-vector prediction section; a deblocking processing section configured to carry out said deblocking process on said decoded image data completing said motion compensation process in accordance with said hybrid prediction information embedded in said motion-vector data; and a memory used for storing said motion-vector data in a state of being accessible to said deblocking processing section,
