INPUT DEVICE, COORDINATE DETECTION METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To provide an input device capable of enhancing detection accuracy of an input position.SOLUTION: An input device 100 comprises: an input operation face 15; a display element 17; a sensor part 1; and a drive part 18. The input operation face 15 includes a display area 15a. The display element 17 displays an operation screen at least a part of which includes an operation area, in the display area 15a. The sensor part 1 comprises multiple electrodes which are individually driven by a scan of an electrical signal and electrostatically detects an input position in the input operation face 15. The drive part 18 comprises a first drive mode driving all of the multiple electrodes and a second drive mode driving some of the multiple electrodes. The drive part 18 calculates a coordinate of the input position by executing the first drive mode or the second drive mode according to the operation area.
