Abstract
The present invention relates to a system and method for real time correction of light output and/or color of an image displayed on a display device. The system comprises: The optical aperture (21) of the optical sensor unit (10) has an acceptance angle such that at least 50%, alternatively 60%, alternatively 70%, alternatively 75% of the light received by the sensor (22) comes from light travelling within 15° of the optical axis of the light sensor (22).
