Abstract

A method for detecting a touched position on a touch panel (100) includes: acquiring a capacitance value (S2, 3) detected in each sensing area (101) of the touch panel; correcting each capacitance value (13), based on a correlation value table (6) that stores therein a numerical influence to be exerted on the capacitance value in each sensing area by the capacitance value in the sensing area adjacent to each sensing area, and calculating a correlation correction value for each sensing area (S4); retrieving the maximum value from among the correlation correction values (S12, 14); 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 (S16), and acquiring the calculated centroid position as a touched position (S17, 15).

Description

technical field [0001] The invention relates to a touch position detection method for detecting a touch position of a touch panel, a touch panel detection method using the touch position detection method, and a touch panel detection device. Background technique [0002] In the past, the known touch panel detects the touch position by using the center of gravity method. The center of gravity method is to calculate the center of gravity position of the electrostatic capacitance value of a plurality of sensing areas by measuring the electrostatic capacitance of the sensing areas arranged in a grid shape (for example, , refer to Patent Document 1). [0003] However, as described above, the method of detecting the position of the center of gravity of the capacitance value of each sensing region as the touch position has a problem of low detection precision of the touch position.
