US Patent 11290743 Interaction of illumination compensation with inter-prediction

Systems and techniques for performing illumination compensation in processing video data include deriving one or more illumination compensation parameters for a block of a picture based on one or more tools which may be used for inter-prediction of the block. Illumination compensation can be selectively applied for the block based on whether bi-directional prediction is to be applied for the inter-prediction of the block. In some cases if it is determined that bi-directional prediction is to be applied for inter-prediction of the block, illumination compensation may be avoided for the block.
