ABSTRACT:
Provides control movement of a display area to an image displayed outside a display screen by means of a touch operation using a touch panel in such a general-purpose environment as a desk-top screen of an operating system. In an example embodiment, a data processing apparatus employs a touch panel unit as an input unit. The data processing apparatus includes an operation event detector for detecting an operation preset, to be distinguished from other normal inputs to the panel touch unit; a cursor movement information generator for generating movement information used to move a cursor positioned at the periphery of a display screen to the outside thereof; a cursor movement controller for moving the position of the cursor on a display image according to the generated movement information; and a virtual screen controller for scrolling an item displayed on the display screen according to a cursor movement.
