INPUT DEVICE, METHOD OF CONTROLLING THE SAME, AND PROGRAM

An input device capable of reducing an error generated in a result of detection of coordinates of an object due to an influence of noise or the like is provided. Evaluation values (E1 to E3) regarding the change in velocity of an object at coordinates of a detection surface indicated by individual coordinate data 32 are calculated on the basis of a series of coordinate data 32 of the same object, and it is determined whether or not there is an error in each coordinate data 32 on the basis of the evaluation values (E1 to E3). Therefore, in a case in which an extreme change in velocity of the object apparently occurs due to the influence of noise or the like, it is possible to accurately determine the error of the coordinate data 32 on the basis of the evaluation values (E1 to E3). Further, since the coordinate data 32 in which it is determined that there is an error in time-series of coordinate data 32 of the same object is corrected with data indicating the same coordinates P as that of coordinate data 32 immediately before such coordinate data 32, the error of the detection result of the coordinates generated by the influence of noise or the like can be effectively reduced.
