Abstract
The invention relates to a method for the correction of the brightness of a raw image generated by a sensor matrix, in which an intensity matching is carried out at picture elements defined by a line coordinate and a column coordinate and at least one intensity value. The intensity matching comprises the application to the intensity values of the picture elements to be corrected of two intensity corrections independent of one another, in dependence on the line coordinate, on the one hand, and in dependence on the column coordinate, on the other hand. The invention furthermore relates to an optoelectronic sensor comprising a correction device. This correction device is matched to carry out the initially described intensity matching.
