摘要

A video encoding device includes: pixel bit length increasing means for increasing a pixel bit length of an input image based on pixel bit length increase information; transform means for transforming output data of the pixel bit length increasing means; entropy encoding means for entropy-encoding output data of the transform means; non-compression encoding means for non-compression-encoding input data; multiplexed data selection means for selecting output data of the entropy encoding means or output data of the non-compression encoding means; and multiplexing means for multiplexing 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 means and a pixel bit length of an image corresponding to the output data of the non-compression encoding means are different from each other.

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.
