Abstract
A display input device includes a control unit for correcting horizontal coordinates of an object to be detected on an xy coordinate plane extending on a touch panel, which are acquired by a proximity sensor, according to an angle of elevation φ, an angle of deviation θ and a vertical distance z between the object to be detected and a surface of the touch panel, φ being the angle of a straight line OC with respect to the surface of the touch panel, the straight line OC extending between a predetermined point O positioned on the touch panel and a predetermined point C positioned outside the touch panel, and θ being the angle between a straight line which is an orthogonal projection of the line OC onto the xy coordinate plane, and an x axis on the xy coordinate plane.
