摘要

PROBLEM TO BE SOLVED: To provide an image encoding apparatus capable of efficiently encoding an image.

SOLUTION: The image encoding apparatus of one embodiment of the present invention comprises a coding mode determination unit, a prediction image generation unit, a storage unit, and an encoding unit. The coding mode determination unit determines a coding mode relating to which of the first image prediction processing or second image prediction processing is used for generating prediction image of a partial area of input images. The prediction image generation unit extracts the prediction assist information by the first image prediction processing and generates a prediction image based on the prediction assist information. The storage unit stores the reproduced image that is based on the prediction image. The encoding unit generates a bit stream comprising data obtained by encoding the coding mode information and prediction assist information.
