According to a preferable embodiment of the present invention, an image processing device firstly informs a relay device of information about detecting an event, when an event is detected. Thereby, reduced is latency required for a synchronization process between the relay device and the image processing device after detecting the event. Also, the image processing device controls whether direction power is activated or is maintained in an inactive state without an external signal received from the relay device. Thereby, the image processing device can be driven at low power. |
