The major surface of the movable capacitor electrode includes a rigidity-increasing feature. The DPE store stores the image data by classifying the image data in a user directory in the server according to the ID information added to the image data. The method comprises a phase of modulating the angular setpoint value in such a way that the said setpoint value uniformly sweeps an angular span of \u03c0 radians and that a temporal derivative of the setpoint is deducted from the precession control prior to the determination of the angular measurement.
