US Patent 11405607 Harmonization between local illumination compensation and inter prediction coding

A video processing method is provided to include: performing a determination, for a conversion between a current block of a video and a coded representation of the video, that a generalized bi prediction (GBI) tool or a multi-hypothesis inter prediction tool is enabled for the conversion or a local illumination compensation (LIC) tool being enabled for the conversion, and performing the conversion based on the determination. The LIC tool includes using a linear model of illumination changes in the current block during the conversion.
