1. A method for controlling a noise processing circuit of a touch panel, the touch panel having a plurality of first sensing axes on a first dimension and a plurality of second sensing axes on a second dimension, the method comprising:

  • selecting at least one reference axis from the plurality of first sensing axes;

    sensing the least one reference axis to generate a first sensed output when the plurality of first sensing axes and the plurality of second sensing axes are not driven;

    generating a noise detection result at least according to the first sensed output; and

    controlling the noise processing circuit according to the noise detection result.
