Abstract: A coding device has a difference calculating unit that calculates a quantized value, which is represented by lower-order bits than a quantization bit rate allocated to a processing unit in image data in a selected coding pattern, from a quantized value obtained by quantizing a pixel value in the processing unit with a maximum quantization bit rate in the coding device, as a difference.

Abstract: A method of automatically controlling a transmission power of a wireless communication apparatus that reduces power consumption and adjusts the transmission power to enable communication to be carried out at an optimum transmission power, and a storage medium which stores the method are provided. At a start of communication, a wireless communication apparatus performs communication while setting the transmission power to the maximum value. Each time when transmission succeeds, the transmission power is reduced by a predetermined amount. When transmission fails as a result of the reduction by the predetermined amount, retransmission is carried out with increasing the transmission power by the predetermined amount. The increased power is set as an optimum transmission power. The power is maintained until transmission fails. When transmission fails after the optimum transmission power is set, transmission power is raised to the maximum value and setting of optimum transmission power is again carried out.

Abstract: A bus communication system for enabling data transfer in synchronized communication is provided, which comprises master circuits, a slave circuit, a bus, and a bus arbitration circuit. Data transfer is performed between the master circuits and the slave circuit via the bus. When a transfer request is output from the master circuits, the right to occupy the bus is given to the master circuit which continuously outputs the transfer request to the same address, not more than a predetermined number of times continuously. When receiving the transfer request from the master circuit, the slave circuit informs the master circuit of the end of bus transfer and whether or not data transfer is ready. When informed that data transfer is ready, the master circuit ends data transfer, and when informed that data transfer is not ready, the master circuit outputs a transfer request to the slave circuit again.

Abstract: A method of automatically controlling a transmission power of a wireless communication apparatus which, in order to reduce power consumption of a wireless communication apparatus, adjusts the transmission power so as to eliminate waste power consumption as much as possible, thereby enabling communication to be carried out at an optimum transmission power, and a storage medium which stores the method are provided. At a start of communication, a wireless communication apparatus performs communication while setting the transmission power to the maximum value (S101). Each time when transmission succeeds, the transmission power is reduced by a predetermined amount (S106). When transmission fails as a result of the reduction by the predetermined amount, retransmission is carried out with increasing the transmission power by the predetermined amount, i.e., returning the transmission power to the immediately previous value (S107). The increased power is set as an optimum transmission power.
