Abstract
A detecting method for a conductive matter on a capacitive sensor device includes obtaining a positive signal, computing a signal summation of a plurality of sensing points in at least an electrode line where the positive signal is occurred, comparing the signal summation to a predetermined value, determining a touch object inducing the positive signal is not an irregular conductive matter if the signal summation is larger than the predetermined value, and determining the touch object inducing the positive signal is the irregular conductive matter if the signal summation is not larger than the predetermined value.
