A detection method for detecting a touch event on a touch panel includes a plurality of first sensing axes on a first dimension, and a plurality of second sensing axes on a second dimension. The detection method includes: regarding each first sensing axis, choosing another first sensing not neighboring with the first sensing axis as a first reference axis, and utilizing the first sensing axis and the first reference axis to derive a first sensing data corresponding to the first sensing axis; utilizing the second axes to derive a second sensing data corresponding to each second sensing axis; and utilizing first sensing data respectively corresponding to the first sensing axes and second sensing data respectively corresponding to the second sensing axes to derive a touch event detection result.
