Claim 7:
8. A touch sensitive processing apparatus, coupled to a touch panel including parallel first electrodes and parallel second electrodes, each of the first electrodes intersects with the second electrodes, the touch sensitive apparatus comprising:
a driving circuit module, configured to transmit a driving signal to one of the first electrodes in a time-sharing manner;
a sensing circuit module, configured to sense the driving signal via the second electrodes of the touch panel in the time-sharing manner; and
a processor module, coupled to the driving circuit module and the sensing circuit module, configured to execute instructions stored in non-volatile memory to realize the following steps:
having the driving circuit module and the sensing circuit module perform mutual-capacitance detection to retrieve an image which comprises two dimensional sensing information;
calculating at least one touching or approximating event corresponding to at least one external conductive object according to the image;
determining whether a surrounding area corresponding to a touching or approximating position of the touching or approximating event is normal;
reporting the touching or approximating event to a host when the surrounding area is determined normal;
calculating a predicted position according to a trajectory corresponding to the touching or approximating position when the surrounding area is determined abnormal;
calculating an adjusted position according to the predicted position and the touching or approximating position; and
reporting the adjustment position to the host when the surrounding area is determined abnormal.
