Touch panel operation devices, methods, and programs set a touch-off determination time, and determine that the touch-off has occurred if the state at which the touch panel detects the user not touching the touch panel has continued for the set touch-off determination time or more after the touch-off was detected. When the user is touching the touch panel, the devices, methods, and programs acquire a touch coordinate, select an object corresponding to the acquired touch coordinate, and scroll-display the selected object based on a displacement of the acquired touch coordinate. The devices, methods, and programs determine whether the touch coordinate was acquired and displaced just before the touch-off was detected, and if the touch coordinate was acquired and displaced just before the touch-off was detected, set the touch-off determination time to be longer than if the touch coordinate was acquired and not displaced just before the touch-off was detected. |
