Method and system for magnifying and displaying local image of touch display device by detecting approaching object
First Claim
1. A method for magnifying and displaying a local image displayed on a touch display device, the touch display device comprising a display panel and a touch panel integrated on the display panel, the touch panel having a touch surface defining an effective touch zone, comprising the following steps:
- (a) detecting if an approaching object is approaching the touch surface in the effective touch zone;
(b) detecting an approaching object position in the effective touch zone of the touch panel where the approaching object heads for, the approaching object position being associated with at least one target graphic representation displayed on the display panel;
(c) determining an approaching altitude of the approaching object on the approaching object position in the effective touch zone of the touch panel with respect to the touch surface of the touch panel; and
(d) magnifying and displaying the target graphic representation associated with the approaching object position based on a first predefined magnification and a predefined image magnification mode setting in relation with a first predefined approaching altitude value when the approaching altitude of the approaching object with respect to the touch surface of the touch panel is detected to be less than the first predefined approaching altitude value.

Abstract
Disclosed are a method and system for magnifying and displaying local image of a touch display device. When an object is detected to be approaching an effective touch zone on a touch surface of a touch panel, the distance or altitude between the approaching object at a position on the effective touch zone of the touch panel where the approaching object heads for and the touch surface of the touch panel is determined. When the distance is less than a first predefined approaching altitude, a target graphic representation associated with the position of the approaching object on the touch panel is first enlarged and then, based on a second predefined approaching altitude, an operation of magnification of the local area or the target graphic representation displayed on a display panel corresponding to the position of the approaching object or execution of an executable object linked to the graphic representation is carried out. The second predefined approaching altitude can be defined as being in contact with the touch surface of the touch panel.

20. A system for magnifying and displaying a local image displayed on a touch display device, the touch display device comprising a display panel and a touch panel integrated on the display panel, the touch panel having a touch surface defining an effective touch zone, comprising:
-
a microprocessor connected to the touch panel and the display panel via a touch panel interface and a display panel interface respectively; an approaching object altitude detection unit connected to the microprocessor and detecting an approaching altitude of an approaching object with respect to the touch surface of the touch panel to provide a detected altitude value to the microprocessor; a program memory connected to the microprocessor and storing a proximity magnification control program; and a proximity control parameter memory connected to the microprocessor and storing at least one redefined approaching altitude and a corresponding magnification ratio; wherein when an approaching object is approaching the touch surface in the effective touch zone of the touch panel, the approaching object altitude detection unit detects if the detected value of the approaching altitude of the approaching object with respect to the touch surface of the touch panel is less than the predefined approaching altitude and the microprocessor executes the proximity magnification control program to magnify a target graphic representation displayed in a local area of the display panel corresponding to an approaching object position on the touch panel where the approaching object is heading for based on the magnification ratio corresponding to the predefined approaching altitude with the approaching object position taken as a reference point. - View Dependent Claims (21, 22, 23, 24, 25)
