Abstract
A method for brightness and color correction of image data of a line camera is disclosed, wherein, for the detecting of image data with at least two line arrays of the line camera while illuminating a detection area of the line camera with an illumination module, a gray-scale image and at least two single-color images are recorded, and the image data is corrected with the help of a brightness function of the illumination module which is dependent on a line position of the line array and/or a distance of recorded objects. The brightness function is determined for the illumination module in advance and independent of the line camera and is stored in the illumination module, and the brightness function is read out by the line camera and used for the respective correction of the gray-scale image and the single-color images.
