摘要

Disclosed is an instructed position determination device of a touch panel for preventing problems caused by statistical processing for calculating an instructed position of a touch panel by an instructing object. A displacement direction A is assumed to be a direction in which a current measurement position, which has been acquired by measurement for detection at a predefined measurement timing related to a contact position at which an instructing object (8) is in contact with a touch panel (7), has been displaced with respect to a previous measurement position which had been acquired by the measurement at the previous measurement timing. A displacement direction B is assumed to be a direction in which the previous measurement position had been displaced with respect to the previous-previous measurement position which had been acquired by the measurement at the previous-previous measurement timing. If an intersection angle ? of the displacement direction A and the displacement direction B is less than or equal to a set angle Q, a position by way of statistical processing on the basis of the plurality of measurement positions for which the measurement timings were different is determined as an position instructed by the instructing object at the current measurement timing. If the intersection angle ? is greater than the set angle Q, the current measurement position is determined as the position instructed by the instructing object at the current measurement timing.
