Title:
IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/060484
Kind Code:
A1
Abstract:
The present disclosure relates to an image processing device and an image processing method which make it possible to suppress degradation of image quality and a decrease in encoding efficiency. The image processing device is provided with: a setting unit which sets identifying information identifying whether the pixels of a current prediction block of an image to be subjected to an encoding process is to be subjected to a motion compensating process in which an optical flow process is applied; and an encoding unit which encodes the image and generates a bit stream including the identifying information set by the setting unit. The present techniques are applicable to, for example, an image processing system in which encoding and decoding are performed according to a versatile video coding (VVC) scheme.
