1. A touch detection circuit, comprising:
a touch detection section circuit configured to detect a plurality of touch points made by one or more users, based on positive data in a touch data map that includes the positive data and negative data; and
a determination section circuit configured to detect, based on the negative data in the touch data map, a plurality of negative points, and determine, based on the plurality of negative points, touch points made by same user in the plurality of touch points,
wherein the touch detection section circuit and the determination section circuit perform processing on a series of the touch data maps, and
wherein the determination section circuit corrects a most-recent result of the determination, based on a result of the determination by the determination section circuit on one or the plurality of touch data maps.
