Abstract:
1. An image navigation apparatus in a mobile station configured to process a plurality of applications, the image navigation apparatus comprising: a display unit configured to display an image related to one of the plurality of applications; a processing unit configured to read coordinates of a reference point and a target point on the image displayed on the display unit to calculate an angle and a distance between the target point and the reference point; and a voltage distributing unit operatively coupled to the processing unit and configured to distribute a voltage to a tilt sensor unit, the voltage distributing unit generating a new reference voltage corresponding to the one of the plurality of applications based on the calculated angle and distance, wherein the tilt sensor unit is configured to sense a tilt of the mobile station by using the new reference voltage, a sensitivity degree of the tilt sensor unit adjusted according to an application being executed such that the sensitivity degree is not the same for all of the plurality of applications, wherein navigation of the displayed image is based on motion of a virtual image on the display unit, wherein the processing unit is further configured to move the displayed image according to the tilt sensed by the tilt sensor unit, wherein the reference point and target point are determined by a position of the displayed image moved if the displayed image is moved according to the sensed tilt, and wherein the target point is generated according to the application being executed such that different reference points and target points are set for each of the plurality of applications.
