Provided is to prevent problems from occurring due to statistical processing for calculating a pointed position being pointed (touched) on a touch panel by a pointer. On a touch panel (7), a touch position of a pointer (8) is measured every predetermined measurement timing. A direction in which the pointer has moved from a preceding measured position to a recent measured position is referred to as a movement direction A. A direction in which the pointer has moved from a further preceding measured position to the preceding measured position is referred to as a movement direction B. If a crossing angle ¸ formed by the movement directions A and B is smaller than or equal to a predetermined set angle, a position resulting from predetermined statistical processing is determined as a pointed position. If the crossing angle ¸ is larger than the set angle, the recent measured position is determined as a pointed position. |
