Abstract
An input apparatus includes a sensor section configured to include a plurality of detection units, and to control positive and negative polarities of a detection signal at each detection position, a control unit configured to generate a group of combined detection signals in which polarity patterns are different from each other, and a signal reproduction unit configured to reproduce signal levels of a group of detection signals on the basis of a group of combined detection signals and a group of polarity patterns, in which at least some of the plurality of detection units differ in the number of detection positions, and the control unit selects the group of polarity patterns according to the number of detection positions so that the number of positive polarities and the number of negative polarities included in each of the polarity patterns are similar to each other.
