Abstract
A processing system for a capacitive sensing device includes a sensor module and a determination module. The sensor module is coupled to transmitter electrodes and receiver electrodes. The sensor module is configured to transmit transmitter signals with the transmitter electrodes and receive resulting signals with the receiver electrodes. The resulting signals include effects corresponding to the transmitter signals. The determination module is configured to determine response values from the resulting signals, and determine a first adjusted response value by applying a negative multiplier to a first response value of the response values. The first response value is a negative value. The determination module is further configured to determine positional information for a first input object based on at least one of the first adjusted response value and a second response value of the response values, and report the positional information. The second response value is a positive response value.
