An array of view-dependent sprited tiles provide different views of an image texture. The invention provides for the characteristic curve to have a degressive characteristic curve profile in order to combine a high measurement sensitivity in the case of small signal charges with a large measurement range through to large signal charges. It also suppresses the change in the coefficient of friction before and after a heat history. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field.
