The ambient illuminance sensor system disclosed herein includes a light sensor to generate a series of ambient illuminance values from an area surrounding a computing device, a human presence sensor configured to detect presence of a human in vicinity of the computing device, and computer implemented instructions for determining ambient illuminance level (AIL) based on at least in part on the series of ambient illuminance values, determining presence of a human in vicinity of the light sensor, and based on at least in part on determining that the AIL is below a threshold and that a human is present, applying a hysteresis filter to process the series of ambient illuminance values.

Ambient illuminance sensor system

A method of providing environmental information to an electronic device includes, at the electronic device, receiving ambient light from a surrounding environment of the electronic device with one or more camera sensors in data communication with a processor and capturing a raw pattern with the camera sensor, wherein the raw pattern includes light intensity information and light spectrum information. The method further includes deriving at least one ambient light value from the light intensity information and light spectrum information and providing the ambient light value to the processor of the electronic device.
