Title:
IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2023023669
Kind Code:
A
Abstract:
To provide an image decoding device, an image decoding method, and a program that can improve coding performance by specifying prediction information and a method for saving prediction information when adding an intra prediction mode in GPM.SOLUTION: In an image processing system having an image encoding device and an image decoding device, the image decoding device includes an inter prediction unit 241 that derives motion information for GPM and generates motion compensation pixels, an intra prediction unit 242 that derives an intra prediction mode for GPM and generates an intra prediction pixel, and a prediction information buffer 244 that stores or outputs prediction information including motion information or an intra prediction mode of a decoding target block to which the GPM is applied and a prediction type that can determine whether either inter prediction or intra prediction is applied.SELECTED DRAWING: Figure 3
