Ambient temperature reporting through infrared facial recognition
First Claim
Patent Images
1. A method of computing, comprising:
- taking an IR image of a user and a background with an IR sensor of a computing device, the computing device being in a location;
segmenting the IR image into user image data and background image data;
detecting one or more ambient temperature distorting features in the background image data;
determining an ambient temperature of the location using the background image data, wherein determining the ambient temperature includes removing the one or more ambient temperature distorting features from the background image data; and
controlling an aspect of the computing device based on the ambient temperature and a calculated skin temperature margin, wherein the calculated skin temperature margin is based on a difference between a maximum allowable computing device external temperature for user skin contact with the computing device and a current computing device external temperature.

Abstract
Various methods an apparatus to use facial recognition in a computing device are disclosed. In one aspect, a method of controlling a component of a computing device is provided. The method includes taking an IR image of a user and a background with an IR sensor of a computing device. The computing device is in a location. The IR image is segmented into user image data and background image data. An ambient temperature of the location is determined using the background image data. An aspect of the component is controlled based on the ambient temperature.
