Abstract
In DBBP, there is a problem because of a large processing amount of a synthesis process in which two complement images are synthesized according to segmentation and a filtering process is executed. A predicted image generation device includes a segmentation derivation section that derives segmentation information from an image; and an image synthesis section that generates a predicted image. The image synthesis section executes a filtering process based on a partition mode and the segmentation information.
Claims3
A predicted image generation device comprising:
- a segmentation section that derives segmentation information of a target block;
- and
- an image synthesis section that generates a predicted image using the segmentation information,
- wherein the image synthesis section generates the predicted image by performing one of at least a first filtering process and a second filtering process according to a value of a partition mode of the target block, wherein one of the at least the first filtering process and the second filtering process includes a shifting process of a target pixel.
