Abstract

A processing system for a capacitive sensing input device comprises a sensor module and a determination module. The sensor module acquires a plurality of capacitive resulting signals by operating a plurality of sensor electrodes for capacitive sensing. The determination module weights values of the plurality of capacitive resulting signals to achieve a plurality of weighted capacitive resulting signals, wherein a first capacitive resulting signal of the plurality of capacitive resulting signals is weighted according to a weighted noise parameter derived from a component of a variable noise associated with a respective sensor electrode used for acquisition of the first capacitive resulting signal, wherein the variable noise varies across the plurality of sensor electrodes. The determination module also determines positional information for an least input object in a sensing region of the capacitive sensing input device based on resulting signals processed from the weighted capacitive resulting signals.
