PROBLEM TO BE SOLVED: To provide an input device capable of reducing the number of times of arithmetic operation, and quickly making a response to an input operation.SOLUTION: An input device includes: a coordinate input part 1 in which a plurality of capacity detection parts 1a are arranged like a matrix, and an operator performs a proximity operation; a capacity measurement part 2 for measuring the electrostatic capacity of each of the plurality of capacity detection parts 1a, and for outputting it as a measurement signal; and a control part 3 for controlling the capacity measurement part 2, acquiring a measurement signal in association with the coordinate information of the capacity detection part 2, performing the arithmetic operation of the measurement signal, and outputting a control signal on the basis of the result. The control part 3 successively determines target coordinates in accordance with the coordinate information of the capacity detection part 1a, and compares the value of the measurement signal of the determined target coordinates with the value of the measurement signal of a plurality of information adjacent to the periphery of the target coordinates, and when the value of the measurement signal of the target coordinates is equal to or more than the value of the measurement signal of the plurality of coordinate information adjacent to the periphery of the target coordinates, detects the target coordinates as an operation point where the operator performs the proximity operation. |
