INPUT DEVICE

WIPO Patent Application WO/2023/248538

A1

Provided is an input device capable of accurately determining an operation input performed by an operating body on an operating object, regardless of the size of the operating body.　The input device comprises: a plurality of electrodes respectively arranged on the back side of a plurality of operation areas corresponding to the plurality of operation areas arranged adjacent to each other; a detection unit that detects capacitance values of the plurality of electrodes; and a determination unit that determines that an operation input by an operating body has been performed on any one of the plurality of operation areas, on the basis of the plurality of capacitance values detected by the detection unit, wherein the determination unit determines that on the basis of a difference value obtained by subtracting, from a capacitance value of one electrode among the plurality of electrodes, a value obtained by multiplying a capacitance value of an electrode adjacent to the one electrode by the coefficient k (0
