According to the invention, first and second image signals of at least the characteristic region are generated with a camera, whereby the first image signals are generated with a first and the second image signals are generated with the first and an additional, second light source having a light emission different from the first. The first and second image signals are subtracted and difference image signals are generated. These difference image signals are investigated in view of the signals generated from the characteristic region, and the location coordinates of the characteristic region are identified, and a corresponding signal is generated.
