BINARY ARITHMETIC CODING DEVICE |
摘要 |
An object of the present invention is to provide a binary arithmetic coding device that allows real-time processing with a higher image quality. At a timing at which a ternary data string for a target bit is outputted, an updated coding range width and an updated range width of less probability are outputted. For that reason, while a binary conversion unit (32) and an f value retention processor (33) convert the ternary data string into a binary data string to output a coded bit, a binary arithmetic re-normalization unit (31) is allowed to perform a processing of binary arithmetic coding for the next bit. |
