1. An input display device, comprising:
a display configured to display an image;
a touch sensor of a capacitive type mounted on the display;
a plurality of three-dimensional operation portions mounted over the touch sensor and capacitively coupled to the touch sensor;
a distance detector configured to detect a distance from an operation object to the touch sensor, in response to an operation by the operation object on a three-dimensional operation portion among the three-dimensional operation portions; and
a determiner configured to determine which one of the three-dimensional operation portions is operated by the operation object, based on the distance detected by the distance detector.
