SENSING BASELINE MANAGEMENT

摘要

A processing system for sensing includes a sensor module that includes sensor circuitry coupled to sensor electrodes, the sensor module configured to acquire a sensor frame, and a determination module connected to the sensor electrodes. The determination module is configured to determine a first delta frame from the sensor frame and a first baseline generated using a first processing mode, and determine a second delta frame from the sensor frame and a second baseline generated using a second processing mode. The second processing mode is different than the first processing mode. The determination module is further configured to determine that the first delta frame and the second delta frame are inconsistent with respect to at least one input object. The processing system copies at least a portion of the second baseline to the first baseline based on the first delta frame and the second delta frame being inconsistent.

1. A processing system for sensing, comprising:
a sensor module comprising sensor circuitry coupled to a plurality of sensor electrodes, the sensor module configured to acquire a first sensor frame; and a determination module connected to the plurality of sensor electrodes and configured to:
determine a first delta frame from the first sensor frame and a first baseline, wherein the first baseline is generated using a first processing mode,determine a second delta frame from the first sensor frame and a second baseline,
wherein the second baseline is generated using a second processing mode, andwherein the second processing mode is different than the first processing mode, anddetermine that the first delta frame and the second delta frame are inconsistent with respect to at least one input object, wherein the processing system copies at least a portion of the second baseline to the first baseline based on the first delta frame and the second delta frame being inconsistent with respect to the at least one input object.
