Abstract:
An apparatus and a method generate a coded block pattern (CBP) of an alpha channel image. An apparatus and a method encode or decode the alpha channel image using the method. The alpha channel image encoding apparatus includes a CBP generator generating a CBP of a first block corresponding to an encoding unit in the alpha channel image by allocating CBPs to a plurality of second blocks that includes the first block; and a bitstream generator generating a bitstream by encoding the CBP or the CBP and pixel values of the second blocks based on the CBP of each of second blocks.
