Image processing device

An image processing device comprising:

• a data processing unit operable to execute data processing of input stream data;
• a power-source-control unit operable to control power supply to the data processing unit;
• a nonvolatile memory unit which has a nonvolatile memory region, and which control information used for data processing is stored in each time of data processing;
• and
• a communication-processing section which exchanges data through a network, accepts input of a processing request for data processing from the data processing unit, and controls the data processing unit and the power-source-control unit,
• wherein the power-source-control unit controls a normal operation mode in which the data processing unit is supplied with power, and a power-saving operation mode in which the data processing unit is supplied with no power,
• the communication-processing section has an event-detection unit operable to detect the processing request, and to control the power-source-control unit based on a result of detection,
• in the power-saving operation mode, the event-detection unit controls the power-source-control unit so that the data processing unit transitions to the normal operation mode on condition that the event-detection unit detects the processing request, and
• the data processing unit acquires control information for execution of data processing corresponding to the detected processing request, from the nonvolatile memory unit, and executes data processing based on the control information.
