Abstract
A prediction mode determining unit of a video encoder comprises a primary evaluative value calculating unit which calculates each primary evaluative value of a plurality of primary evaluative values corresponding respectively to a plurality of 4×4 intra-prediction modes with different prediction directions, for each of a plurality of 4×4-pixel blocks, using the motion picture signal as a reference image signal, a secondary evaluative value calculating unit which calculates each of a plurality of secondary evaluative values corresponding respectively to the 4×4 intra-prediction modes, by applying to the primary evaluative value, weight summing which uses an evaluation coefficient corresponding to a position of each of the 4×4-pixel blocks, determining unit which determines a coding prediction mode for each macro-block, using the secondary evaluative values, and coding unit which codes the motion picture signal in accordance with the coding prediction mode.
