Patent Images
1. A display apparatus comprising:
- a display unit which displays an image;
a sensing unit which generates an infrared (IR) scan image of a surface of the display unit;
an image processing unit which detects touched areas that are touched by a user from the IR scan image, detects an unintentional touched area, from among the touched areas, that has an unintentional touch pattern, and removes the unintentional touched area from the IR scan image; and
a control unit which processes an event corresponding to a remaining touched area from among the touched areas.

10. A touch sensing method comprising:
-
generating an infrared (IR) scan image of a surface of a display unit; detecting touched areas that are touched by a user from the IR scan image; detecting an unintentional touched area, from among the touched areas, that has an unintentional touch pattern; removing the unintentional touched area from the IR scan image; and processing an event corresponding to a remaining touched area from among the touched areas. - View Dependent Claims (11, 12, 13, 14, 15)

16. A touch sensing apparatus comprising:
-
an input unit which receives an IR scan image of a surface of the display unit; an image processing unit which detects a plurality of touched areas that are touched by a user from the IR scan image, detects an unintentional touched area, from among the plurality of touched areas, that has an unintentional touch pattern, and removes the unintentional touched area from the IR scan image; and an output unit which outputs remaining touched areas from among the plurality of touched areas. - View Dependent Claims (17, 18)

19. A display apparatus comprising:
-
a display unit which displays an image; a sensing unit which generates an infrared (IR) scan image of a surface of the display unit; an image processing unit which detects a touched area that is touched by a user from the IR scan image, and determines whether the touched area is an intentional touched area or an unintentional touched area, wherein, if the image processing unit determines that the touched area is the intentional touched area, the image processing unit outputs the intentional touched area, and, if the image processing unit determines that the touched area is the unintentional touched area, the image processing unit removes the unintentional touched area from the IR scan image; and a control unit which processes an event corresponding to the intentional touched area output from the image processing unit. - View Dependent Claims (20)
