Abstract:
1. An image processing apparatus, which operates in a first power state and a second power state different from the first power state, comprising: a pyroelectric sensor configured to detect a heat source within a detection region of said pyroelectric sensor; a determination unit configured to, in a case where said pyroelectric sensor does not detect the heat source after said pyroelectric sensor detected the heat source in the detection region, determine whether or not the heat source has moved outside the detection region based on a position in the detection region at which said pyroelectric sensor last detected the heat source; and a power control unit configured to control, in a case where said determination unit determines that the heat source has moved outside the detection region, the image processing apparatus to change from the first power state to the second power state, and to stay in the first power state, in a case where said determination unit determines that the heat source has not moved outside the detection region.
