Abstract
An input apparatus that accurately determines an input operation intended by a user without erroneously determining an operation including no move as an operation including move. Touch positions in a time period from touch-down to touch-up by an input operation performed on a touch panel by the user are recorded in chronological order. A statistical variance of the touch positions is calculated based on the obtained touch positions. Whether the input operation is an operation including no move or an operation including move is determined based on the calculated variance. When the calculated variance is smaller than a threshold value, it is determined that the input operation is the operation including no move, and when the calculated variance is not smaller than the threshold value, it is determined that the input operation is the operation including move.
