The image sensor (11) has light sensitive sensing elements and/or lighting elements which are arranged in a matrix form, to cover a detection areas (6,7) completely. A control device (12) connected with the sensor, activates or deactivates the sensing elements and/or lighting elements according to the current state of the blade system. The light exposure values are detected by the sensing elements when the sensing elements are activated, so as to form an image. An independent claim is included for method for operating blade system. |
