Title:
IMAGE PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/137643
Kind Code:
A1
Abstract:
The present technology pertains to an image processing device and a method that make it possible to reduce a buffer size. The image processing device divides a unit of processing for calculating a cost used for determination of whether to perform bi-directional prediction into divided units of processing each having a size equivalent to a VPDU size or less than or equal to the VPDU size, and performs determination using the cost calculated on the basis of the divided processing unit. The present technology can be applied to an encoding device or a decoding device.
