Patent Searching and Data


Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2021/060825
Kind Code:
A1
Abstract:
Provided are an image encoding/decoding method and device. An image decoding method of the present disclosure comprises the steps of: deriving an intra prediction value by performing intra prediction for a current block; deriving an inter prediction value by performing inter prediction for the current block; deriving a combined inter and intra prediction (CIIP) value by calculating the weighted sum of the intra prediction value and inter prediction value; and generating a reconstructed block of the current block by means of the CIIP value, wherein the intra prediction can be performed in a planar mode.
