Abstract (en)

[origin: WO2009018958A1] The invention relates to a device and a method for controlling the light emission (1) of at least three light sources (21, 22, 23), wherein the light emitted by the light sources (21, 22, 23) is detected in a sequence of measuring periods during a calibration phase, and calculated on the basis of the information on the brightness of each individual light source (21, 22, 23) obtained during the measuring periods. In at least one of the measuring periods, the detected light comes from a plurality of the light sources (21, 22, 23).
