Title:
IMAGE ENCODER AND IMAGE DECODER
Document Type and Number:
WIPO Patent Application WO/2020/171046
Kind Code:
A1
Abstract:
An image encoder is provided including circuitry and a memory coupled to the circuitry. The circuitry, in operation, responds to a size of a block satisfying a size condition by generating a prediction image using a prediction mode selected from a plurality of prediction modes. The plurality of prediction modes include a first prediction mode in which a prediction process uses a motion vector and a reference block in a same picture as the block. The circuitry encodes the block using the prediction image.
