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.

摘要： Providing a reliable, durable external storage apparatus that is capable of disposing a sensor for fingerprint authentication on its surface of the housing with a simple structure. With respect to a memory substrate 12 to be mounted a semiconductor memory 21, an image sensor 20 on which a sensing surface 20a is provided for fingerprint authentication is mounted at a surface on the opposite side to a surface where a connector 24 is mounted so as to dispose the image sensor 20 directly under a window 31. By adapting a structure such that a protective plate 13C of the substrate holder 13 is held by a holding section 58 in a vertical direction, the memory substrate 12 is protected from damages by external force acting on the substrate holder 13.
