Abstract
In one embodiment, a sensed dataset includes data produced by a plurality of light sensors that have been exposed to a light environment. The data of the sensed dataset corresponds to different ranges of light, and at least a portion of one of the ranges of light is outside the visible (VIS) light spectrum. The sensed dataset is compared to a plurality of known datasets representative of known light environments, and at least one known dataset that is similar to the sensed dataset is identified. In response thereto, an indication of the sensed light environment is provided. Apparatus for implementing this and related methods is also disclosed. In some embodiments, the light sensors are ultraviolet, visible and infrared sensors, and the indication of the sensed light environment is used to control the color of data acquired by an image sensor, or the color of a display backlight.
