Abstract
Provided is a touch detection device, including: a determining unit configured to determine a region of a conductive object based on measurement of a self-capacitance of each of a plurality of electrodes arranged to intersect with each other; and a detecting unit configured to detect the conductive object based on measurement of a mutual capacitance of, among the plurality of electrodes, an electrode corresponding to the region of the conductive object determined by the determining unit, without measuring a mutual capacitance of an electrode outside of the region of the conductive object determined by the determining unit.
