Display devices, methods, and programs detect a position of a user's finger contacting a touch panel. When the user's finger lifts from the touch panel, the devices, methods, and programs detect a distance and a direction from a first position of the user's finger to a second position of the user's finger, in which the user's finger was last detected, calculate a reference moving amount and a moving direction, and update the display position of the image by moving the display position of the image in the moving direction by the reference moving amount, and then update the display position using an updated moving amount, the updated moving amount being the reference moving amount multiplied by a predetermined coefficient of less than one The devices, methods, and programs continue to newly update the display position by repeating the updating of the moving amount.
