摘要:
The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.
