Abstract
An interlayer video decoding method includes: selecting a luminance compensation model to be applied to a first layer reference block and determining a luminance compensation parameter for the selected luminance compensation model; and compensating for luminance of the first layer reference block by using the luminance compensation parameter and reconstructing a second layer image comprising a second layer current block. The determining of the luminance compensation parameter comprises determining the luminance compensation parameter based on any one of a color component of the second layer current block, information about a type of a picture comprising the second layer current block, and a prediction mode of the second layer current block.
