Abstract
A detection value acquirer acquires a plurality of detection values that are based on capacitance of each of a plurality of common electrodes arranged in a matrix. A detection value calculator calculates detection values in a plurality of block regions each containing two or more common electrodes out of the plurality of common electrodes based on the plurality of detection values. A touch detector detects a touch by a conductor on the display screen of a display device based on the detection value of each of the plurality of block regions. The detection value calculator calculates the detection value of each of the plurality of block regions in the display screen based on the detection value of each of the two or more common electrodes included in each of the plurality of block regions.
