Claim Text:
1. A processing system for use with an input device of the type including a sensing region overlapping an input surface, and an array of sensor electrodes configured to form a plurality of proximity pixels and a plurality of force pixels, the processing system communicatively coupled to the array of sensor electrodes and configured to: determine a proximity image indicative of positional information for input objects in the sensing region, based on a variable capacitance associated with each of the plurality of proximity pixels; determine a force image indicative of local deflection of the input surface in response to a force applied by the input objects, based on a variable capacitance associated with each of the plurality of force pixels; determine, from the proximity image, a group of proximity pixels for each input object in the sensing region to obtain a plurality of determined groups of proximity pixels; determine, from the force image, a group of force pixels for each determined group of proximity pixels in the plurality of determined groups of proximity pixels to obtain a plurality of determined groups of force pixels; and determine the force for at least one input object based on the plurality of determined groups of force pixels.
