Abstract
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 () and an f value retention processor () convert the ternary data string into a binary data string to output a coded bit, a binary arithmetic re-normalization unit () is allowed to perform a processing of binary arithmetic coding for the next bit.
