摘要： A method for detecting a touched position on a touch panel includes: acquiring a capacitance value detected in each sensing area of the touch panel; correcting each capacitance value, based on a correlation value table that stores therein a numerical influence to be exerted on the capacitance value in each sensing area by the capacitance value in the adjacent sensing areas, and calculating a correlation correction value for each sensing area; retrieving the maximum value from among the correlation correction values; and defining the sensing area for which the correlation correction value is the maximum value, as a maximum area, calculating a centroid position as to an area including the maximum area and the sensing areas adjacent to the maximum area, based on the correlation correction values, and acquiring the calculated centroid position as a touched position.
