Patent ID: 10663837

Abstract:
In an embodiment a method includes illuminating a scene in a first illumination by identically driving the emitters of a light source such that first exposures and/or first colour values of segments are ascertained by an image sensor, determining first illumination parameters for the segments of the scene, wherein the first illumination parameters are determined based on the first exposures and/or the first colour values, illuminating the scene in a second subsequent illumination by differently driving the emitters based on the first illumination parameters of the segments such that second exposures and/or second colour values of the segments are ascertained by the image sensor, determining second illumination parameters for the segments of the scene, wherein the second illumination parameters are determined based on the second exposures and/or the second colour values and illuminating the scene in a third subsequent illumination by differently driving the emitters based on the second illumination parameters of the segments.
