1. A position detection method performed by one or more processors using a capacitive touch sensor formed with a plurality of line electrodes that are two-dimensionally arranged, the method comprising:
acquiring first two-dimensional data indicating a first distribution of detection values of capacitance on the touch sensor;
recognizing that a foreign object is present in an area on the touch sensor based on the first two-dimensional data;
in response to the recognizing that the foreign object is present in the area on the touch sensor based on the first two-dimensional data, using a first threshold that is lower than a second threshold for detecting a first touch position or touch area inside of the area on the touch sensor in which the foreign object is present; and
detecting the first touch position or touch area inside of the area on the touch sensor in which the foreign object is present based on the first two-dimensional data and the first threshold.
