When a touching object has touched a touch panel, a reference point position RP, a dead zone DZ, and a scroll target position SP* are set based on a touch position TP (Sto S); when the touch position TP has moved outside the dead zone DZ, the scroll target position SP* is updated with the touch position TP (S) and unit scroll control is executed to control a display such that the reference point position RP moves toward the scroll target position SP* (a displayed image is scrolled) (S); wherein, when the touch position TP has moved outside the dead zone DZ, the dead zone DZ is updated such that the position between the touch position TP and the reference point position RP just before the unit scroll control is executed becomes the center position of the dead zone DZ (S).

Display device, control method and program thereof

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.
