Abstract
A display system includes a display unit that is provided to a portable terminal and displays a larger size document image than a size of a display area, a displacement amount calculating unit that calculates a displacement direction and a displacement amount of the portable terminal on a virtual surface set along a display screen of the display unit, and a document image specifying unit that specifies, in the document image, a partial area to be displayed in place of a partial area of the document image displayed on the display unit, based on the displacement direction and the displacement amount that are calculated by the displacement amount calculating unit.
Claims12
A display system, including a processor, comprising:
- a display screen for a portable terminal that displays a larger size document image than a size of a display area;
- a calculating unit, within the processor, for calculating a displacement direction and a displacement amount of the portable terminal on a virtual surface set along the display screen;
- and
- a specifying unit, within the processor, for specifying, in the document image, a first partial area to be displayed in place of a second partial area of the document image currently displayed on the display screen, based on the displacement direction and the displacement amount that are calculated by the calculating unit.
A display method to be executed by a computer, comprising:
- calculating a displacement direction and a displacement amount of a portable terminal on a virtual surface set along a display screen provided to the portable terminal that displays a larger size document image than a size of the display area;
- and
- specifying, in the document image, a first partial area to be displayed in place of a second partial area of the document image currently displayed on the display screen, based on the calculated displacement direction and the calculated displacement amount.
(canceled)
A non-transitory computer-readable storage medium having stored thereon a program for causing a computer to:
- calculate a displacement direction and a displacement amount of a portable terminal on a virtual surface set along a display screen provided to the portable terminal that displays a larger size document image than a size of the display area;
- and
- specify, in the document image, a first partial area to be displayed in place of a second partial area of the document image currently displayed on the display screen, based on the calculated displacement direction and the calculated displacement amount.
