IMAGE PROCESSING APPARATUS AND CONTROL METHOD

摘要

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.

主权项

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; a determination unit configured to determine whether or not the heat source has moved outside a detection region of said pyroelectric sensor; and a control unit configured to control, in a case where said pyroelectric sensor does not detect the heat source after said determination unit determines that the heat source has moved outside the detection region, said image processing apparatus to change from the first power state to the second power state, and to stay in, in a case where said pyroelectric sensor does not detect the heat source before said determination unit determines that the heat source has moved outside the detection region, the first power state.
