<P>PROBLEM TO BE SOLVED: To provide a moving picture encoding apparatus, capable of reducing a circuit scale and saving memory capacity, by achieving an intra-forecast mode decision corresponding to a plurality of macro-block sizes in only one structure. <P>SOLUTION: As buffers for peripheral pixels, the apparatus includes a lateral line buffer 103, a vertical line buffer 104, a lateral line temporary buffer 105, and a vertical line temporary buffer 106. An intra-forecast calculator 107 computes correlations between encoding images and forecasting images of image holders from an encoding A image holder 102a to an encoding D image holder 102d by using pixels in these buffers in accordance with an encoding macro-block size instruction from an intra-forecast control unit 101. A forecasting mode determiner 109 determines the forecasting mode in accordance with the result of computation in the intra-forecasting calculator 107 and the encoding macro-block size. <P>COPYRIGHT: (C)2011,JPO&INPIT |
