The invention relates to a system and a method for evaluating the signals of an electronic image sensor during analysis of the position of the edge of a test piece. The image sensor has a surface that is provided with a plurality of pixels, each of which has a photosensitive area such that each pixel emits an electric output signal according to the light input signal received in the respective pixel position. The intensity of said electric output signal correlates with the light input signal and is evaluated in an evaluation unit as image information. |
