Abstract
An image encoding method for encoding an image, includes: a prediction image generation step of generating a synthesis-prediction image by performing synthesis processing of synthesizing an inter-prediction image and an intra-prediction image 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, a plurality of types of intra predictions are allowed to be used as the intra prediction used for the synthesis processing, and the plurality of types of intra predictions include an in-screen block copy prediction, the synthesis processing includes weighting processing performed to the inter-prediction image and the intra-prediction image, and a weighting parameter in the weighting processing is determined in accordance with a type of the intra prediction.
