Patent ID: 11871028
Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An encoder comprising:
circuitry; and
memory coupled to the circuitry, wherein
in operation, the circuitry:
generates, in an inter prediction mode, a first prediction image of a current block to be processed, based on a derived motion vector; and
generates a final prediction image of the current block by applying an update process to the first prediction image,

candidates for the update process include a first process and a second process,
the first process is a bi-directional optical flow (BDOF) process,
the second process is a process of mixing the first prediction image with a second prediction image generated in intra prediction for the current block, and
in the applying of the update process, the first process and the second process are mutually exclusively applied.
