Abstract
Provided is an image processing device which includes: an event detector configured to detect a first event occurring at the AP by analyzing a response signal which the AP transmits to a transceiver of a camera in response to a query signal transmitted from the transceiver to the AP; and a power controller configured to place a sensor, the transceiver and a plurality of other elements constituting the camera in an activated state, in response to the event detector detecting the first event, wherein the power controller places the other elements in a deactivated state while at least one of the sensor and the transceiver is in the activated place, unless the first event is detected by the event detector, a second event is detected by the sensor, or a predetermined setting is provided.
