Title:
IMAGE DECODING DEVICE, IMAGE ENCODING DEVICE, IMAGE PROCESSING SYSTEM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/044985
Kind Code:
A1
Abstract:
This image decoding device is provided with: a filter processing unit that applies a filter process to a block boundary between a target block and an adjacent block that is adjacent to the target block; and a control unit that sets the intensity of the filter process, on the basis of the result of a comparison between a threshold value and the block size of at least either one of the target block and the adjacent block. When a first condition is satisfied, the control unit sets, as the threshold value, a first threshold value. When a second condition different from the first condition is satisfied, the control unit sets, as the threshold value, a second threshold value different from the first threshold value.
