Abstract
A position detection circuit and position detection method are provided to enable more flexible position detection even if an object is present above a touch sensor. The position detection circuit is connected to a capacitive touch sensor formed with a plurality of line electrodes that are two-dimensionally arranged. At least one memory device stores processor-readable instructions that, when executed by at least one processor device, cause the position detection circuit to: recognize an electrically conductive object located above a touch sensor based on two-dimensional data indicating detection values regarding capacitance, and detect a touch position or touch area on the touch sensor based on the two-dimensional data using different touch detection conditions for an outside and an inside of an area where the object is present.
