Ambient light sensing technique

摘要

A method for controlling characteristics of an electronic device based on ambient light levels is provided. In one embodiment, the method includes receiving light at an ambient light sensor of a device and measuring components, such as color components, of the visible light. The component levels may be weighted differently by factors that vary based on the intensity of the light received by the ambient light sensor. Also, the brightness level of a light source in the device or color output of the device may be controlled based on the weighted component levels. Additional methods, systems, and devices relating to control of an electronic device based on sensed ambient light are also disclosed.

1. A method, comprising:
measuring ambient light levels via an ambient light sensor of an electronic device including a display; detecting that the measured ambient light levels have decreased from a photopic range to a sub-photopic range; determining whether to apply dark adaptation compensation to adjust a color output of the display; gradually adjusting the color output of the display to compensate for a gradual color shift that would otherwise be perceived by a user due to dark adaptation when it is determined to apply dark adaptation compensation; and maintaining the color output of the display when it is determined not to apply dark adaptation compensation.
