Abstract

An image forming apparatus includes: an accepting unit to accept user operations to transition the apparatus from a standby state to a power save state; a detecting unit to detect objects around the apparatus; and a power control unit to transition the apparatus from the power save state to the standby state according to detection of an object by the detecting unit, and to transition the image forming apparatus from the standby state to the power save state according to user operations accepted at the accepting unit. The power control unit prohibits the apparatus from transitioning from the power save state to the standby state according to the detection of the object, until a user, which performed operations accepted by the accepting unit to transition the apparatus from the standby state to the power save state, thereafter ceases to be detected by the detecting unit.

First claim

What is claimed is:

1 . An image forming apparatus, having at least a standby state, and a power save state which consumes less power than the standby state, the image forming apparatus comprising:
an accepting unit configured to accept user operations to transition the image forming apparatus from the standby state to the power save state; a detecting unit configured to detect objects around the image forming apparatus; and a power control unit configured to transition the image forming apparatus from the power save state to the standby state in accordance with detection of an object by the detecting unit, and to transition the image forming apparatus from the standby state to the power save state in accordance with user operations accepted at the accepting unit; wherein the power control unit prohibits the image forming apparatus from transitioning from the power save state to the standby state in accordance with detection of an object by the detecting unit, until a user, which has performed operations accepted by the accepting unit to transition the image forming apparatus from the standby state to the power save state, thereafter ceases to be detected by the detecting unit.
