Abstract: A touch panel device includes: a detection unit that detects coordinates of a pressed point on an input surface of a touch panel; and a correction unit that corrects the coordinates detected by the detection unit to obtain corrected coordinates, wherein the correction unit approximates, when a predetermined number of reference points arranged on the input surface are pressed, curves passing through coordinates of the reference points by second order or higher order polynomial equations, specifies, when an arbitrary point on the input surface is pressed, a region including coordinates of the arbitrary point from regions obtained by dividing the input surface by the curves, calculates distances from the coordinates of the arbitrary point to curves that define the specified region among the curves with the second order or higher order polynomial equations, and calculates the corrected coordinates based on a location of the specified region and the distances.
