Abstract: A method and an apparatus adapted to a capacitive touch panel for drift compensation are provided, wherein the touch panel includes a plurality of sensors. In the method for drift compensation, a plurality of capacitances respectively sensed by each of the sensors are extracted. Whether the touch panel is in a proximity state is determined upon a slope of the sensed capacitances and a slope parameter. Whether each of the capacitances is drifted is determined upon the capacitance and an allowable noise range. When the touch panel is not in the proximity state and each of the capacitances is drifted, each of the capacitances is compensated according to a drift error of each of the capacitances after a first presetting time has passed.
