Abstract:
1. A video encoding device comprising: a pixel bit length increasing unit which increases a pixel bit length of an input image based on pixel bit length increase information; a transform unit which transforms output data of the pixel bit length increasing unit; an entropy encoding unit which entropy-encodes output data of the transform unit; a non-compression encoding unit which non-compression-encodes input data; a multiplexed data selection unit which selects output data of the entropy encoding unit or output data of the non-compression encoding unit; and a multiplexing unit which multiplexes the pixel bit length increase information in a bitstream, wherein a pixel bit length of an image corresponding to the output data of the entropy encoding unit and a pixel bit length of an image corresponding to the output data of the non-compression encoding unit are different from each other.
