Abstract
An image decoding device includes: a prediction signal generation unit that generates a prediction signal by intra prediction, wherein in a block to which intra sub-partitions are applied, the prediction signal generation unit refers to a pixel of a decoded block adjacent to the block when generating prediction signals of all sub-blocks in the block.
Claims3
An image decoding device comprising:
- a prediction signal generation unit that generates a prediction signal by intra prediction, wherein
- in a block to which intra sub-partitions are applied, the prediction signal generation unit refers to a pixel of a decoded block adjacent to the block when generating prediction signals of all sub-blocks in the block, in a case where sizes of the sub-blocks are less than a first threshold value.
An image decoding method comprising:
- generating a prediction signal by intra prediction, wherein
- in the generating, in a block to which intra sub-partitions are applied, a pixel of a decoded block adjacent to the block is referred to, when generating prediction signals of all sub-blocks in the block, in a case where sizes of the sub-blocks are less than a first threshold value.
A non-transitory computer readable medium with instructions thereon that when executed by a processor of an image decoding device, cause the processor to execute:
- generating a prediction signal by intra prediction, wherein
- in the generating, in a block to which intra sub-partitions are applied, a pixel of a decoded block adjacent to the block is referred to when generating prediction signals of all sub-blocks in the block, in a case where sizes of the sub-blocks are less than a first threshold value.
