US 11,029,780 B1 · Dynamic rescan to reduce landing artifacts

Abstract

A method and apparatus for dynamically rescanning an array of sensor electrodes of an input device. The input device performs a first scan of the array over a plurality of iterations to acquire a frame of sensor data, where a different subframe of the sensor data is acquired from each iteration of the first scan. During each iteration of the first scan, the input device compares the subframe of sensor data acquired from the iteration with a respective subframe of sensor data acquired prior to the iteration. In some implementations, the input device may selectively repeat one or more iterations of the first scan based on the comparison.

Dependent claims

A controller for an input device, comprising:

processing circuitry;
and a memory storing instructions that, when executed by the processing circuitry, causes the controller to:
perform a first scan of an array of sensor electrodes over a plurality of iterations to acquire a frame of sensor data, wherein a different subframe of the sensor data is acquired from each iteration of the first scan;
compare, during each iteration of the first scan, the subframe of sensor data acquired from the iteration of the first scan with a respective subframe of sensor data acquired prior to the iteration of the first scan;
and selectively repeat one or more iterations of the first scan based on the comparison.
