  • Patent number: 10412417
    Abstract: The present technique relates to an image processing device and method capable of performing an encoding process or a decoding process on an image at high speed. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to a variable length (fixed length) decoding process together. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to an arithmetic decoding process together. Accordingly, since the alternations of firmware and hardware are performed together, it is possible to improve the processing efficiency of decoding. As a result, it is possible to perform the process at high speed. The present disclosure can be applied to image processing devices, for example.

  • Patent number: 9424557
    Abstract: A communication unit connects an e-mail data transfer protocol to transfer e-mail data item via near-field wireless communications with an external device. A retrieval unit retrieves the e-mail data item transferred from the external device when the protocol is connected. A storage unit stores the retrieved e-mail data item. A control unit causes the external device to transfer the e-mail data item in each indication unit of the indication device thereby to cause the storage unit to store the retrieved e-mail data item, when the protocol is connected, and even when a user does not implement a browsing operation of an e-mail list. The control unit further causes an indication device to indicate the e-mail list of the stored e-mail data item when the user implements the browsing operation.
