Abstract
An image encoding method for encoding an image includes: a prediction image generation step of generating a prediction image of a synthesis prediction by performing synthesis processing of synthesizing a prediction image of an in-screen block copy prediction and a prediction image of an intra prediction different from the in-screen block copy prediction, to an encoding-target block; and an encoding step of encoding a difference between the prediction image generated in the prediction image generation step and a pixel value of an image of the encoding-target block, the synthesis processing includes weighting processing performed to the prediction image of the in-screen block copy prediction and the prediction image of the intra prediction that is different from the in-screen block copy prediction, and a weighting parameter of the prediction image of the intra prediction in the weighting processing is determined by information of an adjacent block adjacent to the encoding-target block.
