Abstract
In one embodiment, an image encoding apparatus converts bit depth of an input image formed of a plurality of pixels each having an N bit depth into an (N+M) bit depth larger than N bit depth by M bits. An adaptive bit depth converter converts the bit depth of each pixel of the decoded image of the (N+M) bits into the N bits selectively using one of a plurality of conversion systems. The converted image of the N bit depth is stored in a frame memory as a reference image. The bit depth of each pixel of the reference image of the N bit depth read out from the frame memory is converted into the (N+M) bit depth larger than the N bit depth by M bits in accordance with the conversion system by a pixel bit depth inverse converter.
