Method and apparatus for video encoding and decoding based on illumination compensation

An apparatus for video decoding comprising electronic circuitry adapted for:

• determining a set of parameters for illumination compensation associated with a first motion compensated reference block of a current block in a picture based on a function of samples of the first motion compensated reference block and samples of a second motion compensated reference block of the current block;
• processing a prediction of the current block based on the set of parameters, the prediction being associated with the first motion compensated reference block;
• and
• decoding the current block based on the processed prediction.
