  • Publication number: 20220046157
    Abstract: A method for processing measured data of an image sensor. The method includes reading in measured data that have been recorded by light sensors in the surroundings of a reference position on the image sensor. The light sensors are situated around the reference position on the image sensor. Weighting values are read in, each of which is associated with the measured data of the light sensors in the surroundings of a reference position, the weighting values for light sensors situated at an edge area of the image sensor differing from weighting values for light sensors situated in a central area of the image sensor, and/or the weighting values being a function of a position of the light sensors on the image sensor. The method includes linking the measured data of the light sensors to the associated weighting values to obtain image data for the reference position.
