Abstract
To provide an intra prediction apparatus which can circumvent a hazard problem and improve the time reduction effect. An intra prediction apparatus 11 performs intra predictions of a picture. The intra predictions include: second intra predictions of respective second blocks (blocks) which are obtained by dividing a first pixel block; and a first intra prediction of the first block (macroblock) which constitutes the picture. The intra prediction apparatus 11 includes: an intra prediction unit (a prediction unit 113, an orthogonal transform and quantization unit 115, an inverse orthogonal transform and inverse quantization unit 116, and an adder 117) which performs the intra predictions; and a control unit 119 which controls the intra prediction unit to perform in parallel the intra prediction of the macroblock and the intra predictions of the respective pixel blocks.
