<p>The present invention relates to a touch sensing system and a noise reduction method thereof. The noise reduction method comprises the steps of: converting signals received from touch sensors into digital data and generating data using touches; mapping, to a preset window, the data generated by using the touches and calculating local statistics parameters including an average value and a variation value of (N-2)^th to N^th data (N is a positive integer); calculating a filter coefficient of a local Gaussian filter, based on the local statistics parameters; and correcting the N^th data using the local Gaussian filter, and shifting the window to correct other data.</p> |
