Abstract:
If a pyroelectric sensor does not detect a heat source after it is determined that the heat source has moved outside a detection region of the pyroelectric sensor, an image processing apparatus is controlled to change from a first power state to a second power state. If the pyroelectric sensor does not detect a heat source before it is determined that the heat source has moved outside the detection region of the pyroelectric sensor, the first power state is stayed in.
