Claim Text:
1. A touch device, comprising: a touch panel with a plurality of touch regions; a touch detecting unit coupled to the touch panel to detect a plurality of touch values to which the touch regions correspond; a value obtaining unit coupled to the touch detecting unit to receive a plurality of first touch values to which the touch regions correspond during a first frame period, a plurality of second touch values to which the touch regions correspond during a second frame period, and a plurality of third touch values to which the touch regions correspond during a third frame period, and to perform a value obtaining operation for each of the touch regions to output a median of the first touch value, the second touch value and the third touch value; and a touch point determining unit coupled to the value obtaining unit to determine a real touch point according to a touch threshold and the median of the first touch values, the second touch values and the third touch values outputted by the value obtaining unit, wherein the touch point determining unit determines a touch point according to the touch threshold and the medium of the first touch values, the second touch values and the third touch values outputted by the value obtaining unit, and when a first sum is equal to or greater than a touch point determining value, the touch point is determined as the real touch point by the touch point determining unit, and when the first sum is less than the touch point determining value, the touch point is determined as a false touch point, where the first sum is a sum of the touch values of a touch region to which the touch point corresponds and four adjacent touch regions thereof.
