Title:
IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND IMAGE DECODING PROGRAM
Document Type and Number:
Japanese Patent JP2023099775
Kind Code:
A
Abstract:
To provide a technique for improving encoding efficiency by performing block division suitable for image encoding and decoding.SOLUTION: A block division unit includes: a four division unit that generates four blocks by dividing each of a horizontal direction and a vertical direction of a target block in half to realize four division of the target block; and a 2-3 division unit that generates two or three blocks by dividing the target block in recursive division into two or three in the horizontal direction or the vertical direction. The 2-3 division unit prohibits horizontal division of the target block in a case in which the target block is horizontally divided, when the divided target block exceeds a right side of a picture boundary, and prohibits vertical division of the target block in a case in which the target block is vertically divided when the divided target block exceeds a lower side of the picture boundary.SELECTED DRAWING: Figure 2
