A method for adaptive illuminance compensation based on object and an apparatus using it

摘要

A method for compensating brightness according to an embodiment of the present invention includes receiving a bitstream including an encoded image; Performing predictive decoding on the bitstream according to an intra mode or an inter mode; And compensating the brightness of the current picture to be decoded according to the previously decoded predicted picture brightness, and the compensating the brightness adaptively compensates for each pixel unit based on depth information included in the bitstream. Includes steps.
