Image processing apparatus having plurality of power modes and method of controlling the same

摘要

An image processing apparatus includes a living body detection unit configured to detect approaching of a living body based on a detection output depending on a distance to the living body, an operation unit configured to receive an operation command from a user, a history recording unit configured to record a history of a detection output of the living body detection unit and a history of an operation performed on the operation unit, and a determination unit configured to determine a threshold value of the detection output, the threshold value being used by the living body detection unit as a determination reference value in determining whether a living body is detected, the determination of the threshold value being made based on the history recorded in the history recording unit as to the detection output of the living body detection unit and as to the operation performed on the operation unit.

主权项

1. An image forming apparatus which is capable of operating in a first power mode and in a second power mode in which less electric power is supplied than in the first power mode, the image forming apparatus comprising:
a detection unit configured to detect an object; an operation unit configured to receive user's operation for changing a power mode of the image forming apparatus; a power control unit configured to change the power mode of the image forming apparatus from the second power mode to the first power mode in a case where the detection unit detects an object or in a case where the operation unit receives the user's operation; and a determination unit configured to determine a range of detection of the detection unit, based on an operation history of the operation unit and a detection history of the detection unit.
