Abstract
A method of sensing a level of ambient light in an electronic device comprising sensing a combined light level of ambient light and light from the display, integrating this to determine an integrated light level, determining an integrated display light level, and compensating the integrated light level using the integrated display light level to determine the ambient light level. The device modulates the display between first and second brightness levels and determining the integrated display light level comprises sensing a combination of light from the display and ambient light when at each of the first and second brightness levels, determining a difference, and applying a calibration value to the difference to determine the integrated display light level.
