    Abstract: Provided is an illumination and contrast compensation method applied to the frames comprising multi-view video sequence. Relations between the values of the pixels of the reference block and the values of the pixels neighboring the reference block and relations between the restored values of the pixels neighboring the current block and the values of the pixels neighboring the reference block is determined. An illumination and contrast compensation parameters for illumination and contrast compensation of discrepancy (mismatch) compensation between reference and encoded blocks is determined on the basis of the determined relations, values of the pixels of the reference block, restored values of the pixels neighboring the current block and values of the pixels neighboring the reference block.
