Abstract

The computational complexity when a block configuration in an encoding target region is determined is reduced while the degradation of coding efficiency is suppressed. A video encoding apparatus includes a block selecting unit which selects each of blocks obtained by recursively dividing an encoding target block as a target block in a predetermined sequence, a block size acquiring unit which acquires the smallest block size in an adjacent block for the selected target block, an evaluation value calculating unit which calculates an evaluation value of the target block if a block size of the target block matches any one of the acquired block size, the block size one level higher than the acquired block size, and the block size one level lower than the acquired block size, and a block configuration determining unit which determines a combination of the blocks constituting the region within the encoding target block based on the evaluation value.
