Title:
CODING DEVICE, DECODING DEVICE, CODING METHOD, AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/054784
Kind Code:
A1
Abstract:
The present invention relates to intra-prediction and loop-filter processing for intra refresh. A coding device (100) divides one picture included in a plurality of pictures into a plurality of regions, subjects an entire region among the plurality of regions to intra-coding, and switches the region to be subjected to intra-coding for each picture included in the plurality of pictures. For at least one of generation of a reference pixel for inter-prediction and loop-filter processing, among a plurality of pixels of the pictures included in the plurality of pictures, only the pixels in the region that has been subjected to intra-coding, or only the pixels in a region which precedes the intra-coded region in coding order are used.
