Abstract: A method includes obtaining a partial frame by sampling parts of a frame from a touch panel which comprises an array of sensor areas (step S1). The method also includes generating, based on the partial frame, a new frame which comprises estimates of the un-sampled parts (step S2). The method also includes determining whether at least one touch event is present in the new frame (step S3), and upon a positive determination, for each touch event, determining a location of the touch event in the new frame and obtaining a sub-frame by sampling a region of a subsequent frame from the touch panel frame at and around the location (step S4). The method also includes outputting touch information based on one or more sub-frames (step S7).

Abstract: A method is described including receiving (S3) a first array of values obtained from measuring an array of touch panel sensor areas (Fig.4; In,m ). The method also includes generating (S4) a second array of values based on subtracting a reference array of values from the first array of values. The method also includes determining (S5) presence of at least one touch event in dependence upon the second array of value and, upon a negative determination (S8) generating a new reference array based on exponential smoothing of the reference array and the first array using a weighting factor, wherein the weighting factor is zero, and storing the new reference matrix and, upon a positive determination (S6) outputting the second array.
