Abstract: An input device includes a coordinate input unit including capacitance detectors, a capacitance measuring unit that measures the capacitances of the capacitance detectors and outputs them as measurement signals by performing A/D conversion, and a control unit that controls the capacitance measuring unit, obtains the signals while associating them with coordinate information of the capacitance detectors, calculates first data signals that are difference values between the measurement signals and a reference value, performs a calculation for the first data signals, outputs control signals based on the calculation result, performs a first calculation in which the first data signals obtained after performing a noise removal process are associated with the coordinate information as second data signals and a second calculation in which the second signals obtained after performing a smoothing process are associated with the coordinate information as third data signals, and calculates an operation position using the third data signals.
