Abstract
A method for light sensing senses the light during a sub-frame of a picture frame operated display. The sensing is performed during an adaptive observation window which is determined in dependence on the duty cycle of the operation of the display. A calculation that uses the light sensed during the observation window and the light sensed during the sub-frame delivers a value indicative of the amount of received ambient light.
