Title:
DEVICE AND METHOD FOR ENCODING OR DECODING IMAGE
Document Type and Number:
WIPO Patent Application WO/2018/074812
Kind Code:
A1
Abstract:
The present invention relates to efficiently signaling an intra-prediction mode for predicting a current block in intra-prediction coding. According to an aspect of the present invention, an image-encoding device divides dozens of intra-modes into groups and selects a group to which a real intra-mode of a current block to be encoded belongs, and the image-encoding device signals a value corresponding to the group. An image-decoding device acquires, from a bitstream, information on the group to which the real intra-mode of the current block belongs, and then selects a final intra-mode by assessing intra-modes belonging to the group.
