Abstract
A method is proposed for controlling a display parameter of a mobile device. The mobile device comprises a display and a first imaging unit. The method comprising the step of positioning and orienting the display with respect to a reference plane located at a reference position, such that the first imaging unit faces towards the reference plane. Then a first image is generated by means of the first imaging unit, wherein the first image depends on ambient light incident on the first imaging unit and emitted from at least one ambient light source. A first light level is calculated from the first image, wherein the first light level is indicative of a first fraction of the incident ambient light which illuminates the reference plane by means of specular reflection of the incident ambient light at the display. Finally, the display parameter is adjusted depending on the first light level.
