Abstract

The image data of a camera system is corrected. The camera system includes a color camera which supplies three output signals to three separate color channels, in the form of output signal vectors. The output signal vectors, the coefficients of which represent the output signals supplied by the color camera to the three color channels in a specific position lying in the range of observation, are multiplied by a correction matrix, particularly a square one. The corrected output signal vectors are then processed further in the camera system.
