Patent ID: 8154585

Claim:
A method for decoding a multiview video signal, with a decoder, comprising: receiving, with a Network Abstraction Layer parsing unit, a bitstream comprising encodings of multiple views of the multiview video signal, each view comprising multiple pictures segmented into multiple segments; extracting, with the Network Abstraction Layer parsing unit, first flag information associated with a slice of the multiview video signal from the bitstream indicating whether illumination compensation of the slice of the multiview video signal is enabled; and for the slice in which illumination compensation is enabled according to the first flag information, extracting, with the Network Abstraction Layer parsing unit, from the bitstream second flag information associated with a current block within the slice and determining whether illumination compensation of the current block is to be performed according to the second flag information; and for the current block associated with the second flag information that indicates that illumination compensation is to be performed, deriving, with an average pixel value prediction unit, a predictor for illumination compensation of the current block using an offset value for illumination compensation of at least one neighboring block adjacent to the block, and extracting, with a difference-value decoding unit, a residual value for illumination compensation of the current block from the multiview video signal, and obtaining, with an illumination compensation unit, an offset value for illumination compensation of the current block by forming a sum that includes the predictor for illumination compensation of the current block and the residual value for illumination compensation of the current block, wherein the offset value indicates a difference value between an average pixel value of the current block an average pixel value of a reference block, the reference block being referred by the current block.
