Abstract
An image forming apparatus provided with a sensor including a plurality of elements that detect temperature in the vicinity of the image forming apparatus includes an acquisition unit that obtains temperature data indicating the temperature detected by each of the plurality of elements, a calculation unit that calculates a feature point of a heat source region in the vicinity of the image forming apparatus based on obtained plurality of pieces of temperature data, and a recover unit that causes the image forming apparatus to recover from a power saving state based on a position of the calculated feature point.
Claims26
An image forming apparatus having a sensor including a plurality of elements and each of the plurality of elements outputs temperature data, the image forming apparatus comprising:
- one or more processors;
- and
- memory, wherein one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including:
- instruction for identifying elements that output temperature data which is higher than a reference temperature among the plurality of elements;
- instruction for identifying a heat source region where the number of elements is largest from among a plurality of heat source regions formed by the identified elements;
- instruction for determining one or more feature parameters of the identified largest heat source region;
- and
- instruction for shifting a power state of the image forming apparatus based on the one or more the determined feature parameters.
A method for controlling an image forming apparatus including a sensor including a plurality of elements and each of the plurality of elements outputs temperature data, the method comprising:
- identifying elements that output temperature data which is higher than a reference temperature among the plurality of elements;
- identifying a heat source region where the number of elements is largest from among a plurality of heat source regions formed by the identified elements;
- determining one or more feature parameters of the identified largest heat source region;
- and
- shifting a power state of the image forming apparatus based on the one or more the determined feature parameters.
