Abstract: Disclosed herein is an apparatus for monitoring an image with low power including: an image sensor unit; a low compression unit encoding image data acquired by the image sensor unit with a first compression rate; an event sensor unit generating an event signal when an event is sensed; a high compression unit operated by receiving the event signal and encoding the image data of the image sensor unit and the low compression unit with a second compression rate higher than the first compression rate; and a memory unit storing the image data encoded by the low compression unit and the high compression unit.

Abstract: An event sensing method using a frequency component in a surveillance camera comprises the steps of: obtaining at least one of a plurality of frequency components for a first frame of a digital image and at least one of a plurality of frequency components for a second frame after the first frame of the digital image; and sensing whether an event occurs in a digital image corresponding to the second frame by using the at least one of the plurality of frequency components for the first frame and the at least one of the plurality of frequency components for the second frame.
