A method for processing signals from a touchscreen panel includes obtaining a partial frame by sampling parts of a frame from a touch panel which comprises an array of sensor areas (step S). The method also includes generating, based on the partial frame, a new frame which comprises estimates of the un-sampled parts (step S). The method also includes determining whether at least one touch event is present in the new frame (step S), 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 S). The method also includes outputting touch information based on one or more sub-frames (step S).
