Abstract

A capacitive sensor-based input device for coordinate data input includes an input unit that detects the variation of capacitances at a plurality of detection points, and a control unit that calculates detection outputs from the plurality of detection points to detect the peak position in the variation of capacitances to generate coordinate data. When the maximum value detected at any one of the detection points transitions relative to the previous and following values by less than a first threshold value, the coordinate data is cancelled. When it varies by more than the first threshold value but less than a second threshold value, a corrected value to generate the coordinate data is decreased, thereby suppressing an oscillation of a cursor on a screen while a finger rests on the input device.
