Abstract
An image forming apparatus is operable at least in a first power state and in a second power state, in which electric power consumption in the second power state is less than electric power consumption in the first power state. The apparatus includes a detection unit formed by a plurality of elements disposed to detect the temperature of an object, and a control unit configured to control the image forming apparatus in such a way as to shift from the second power state to the first power state based on a detection result obtained by the detection unit at first timing and a detection result obtained by the detection unit at second timing.
Claims11
An image forming apparatus that is operable at least in a first power state and in a second power state, in which electric power consumption in the second power state is less than electric power consumption in the first power state, the image forming apparatus comprising:
- a sensor having a plurality of elements arranged in a two-dimensional array and configured to sense a human around the image forming apparatus;
- one or more processors;
- and
- one or more memories that store instructions to be executed by the one or more processors, the instructions including:
- instruction for outputting size of one area comprised of elements outputting a predetermined value or greater;
- instruction for shifting a power state of the image forming apparatus to the first power state from the second power state based on the output size of the one area regardless of a shape of the one area.
A method for controlling an image forming apparatus, which is operable at least in a first power state and in a second power state, in which electric power consumption in the second power state is less than electric power consumption in the first power state, and includes a sensor formed by a plurality of elements arranged in a two-dimensional array, the control method comprising:
- sensing a human around the image forming apparatus;
- outputting size of one area comprised of elements outputting a predetermined value or greater;
- and
- shifting a power state of the image forming apparatus to the first power state from the second power state based on the output size of the one area regardless of a shape of the one area.
