1. An input detection apparatus that detects an input position of an input operation performed via an input means with respect to a display panel including a display, a first sensor of a capacitive type, and a second sensor of an infrared type, the input detection apparatus comprising:
a first position detection pressing circuit that detects a first position of the input operation at the first sensor;
a second position detection pressing circuit that detects a second position of the input operation at the second sensor; and
an input position detection pressing circuit that detects the input position with respect to the display panel based on the first position detected by the first position detection pressing circuit and the second position detected by the second position detection pressing circuit,
wherein the input position detection pressing circuit calculates a correction amount based on a difference between a coordinate of the first position and a coordinate of the second position, and detects, as the input position, a coordinate obtained by adding the calculated correction amount to the coordinate of the first position or the coordinate of the second position.
