MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202527099026 A) filed by Mediatek Inc. on October 14, 2025, for Methods And Apparatus Of Local Illumination Compensation Model Derivation And Inheritance For Video Coding.
Inventors include Lai, Chen-Yen; Lo, Chih-Hsuan; Chuang, Cheng-Yen; Chuang, Tzu-Der; Chen, Ching-Yeh; Hsu, Chih-Wei; and Chen, Yi-Wen.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A method and apparatus for video coding using LIC coding tool are disclosed. According to one method, initial inherited LIC parameters are determined for the current block. The initial inherited LIC parameters is modified to generate one or more sets of refined inherited LIC parameters. At least one of one or more refined candidates associated with said one or more sets of refined inherited LIC parameters is inserted into at least one of one or more merge candidate lists. According to another method, two or more merge candidate lists are determined. A merge list index for selecting one target merge list from said two or more merge candidate lists is signalled or parsed. According to the merge list index, an LIC (Local Illumination Compensation) parameter index for selecting one or more target LIC parameters is signalled or parsed.
