Patent ID: 8884912

Claim:
An electrostatic capacitance type input device comprising: a plurality of first detection electrodes arranged in a first direction and respectively extending in a second direction intersecting the first direction; a plurality of second detection electrodes arranged in the second direction and respectively extending in the first direction; a storage unit that respectively stores values obtained through each of the first detection electrodes resulting from a change in electrostatic capacitance between a first conductor and each of the first detection electrodes as first direction detection values, and respectively stores values obtained through each of the second detection electrodes as a result of a change in electrostatic capacitance between the first conductor and each of the second detection electrodes as second direction detection values; and a calculation unit, wherein the calculation unit executes: processing for generating a plurality of first map values obtained by arithmetic processing of a first value obtained by arithmetic processing of at least any of the plurality of first direction detection values and a second value obtained by arithmetic processing of at least any of the plurality of second direction detection values, and processing for determining whether or not the first conductor has approached the plurality of first detection electrodes and the plurality of second detection electrodes by using the plurality of first map values, and each of the first map values is a value obtained by exponentiating a sum of any one of the plurality of first values and any one of the plurality of second values.
