Systems and methods for decoupling image generation rate from reporting rate in capacitive sensing

摘要

The embodiments described herein provide devices and methods that facilitate improved input device resistance to the effects of errors that may be caused by the motion of detected objects on such input devices, and in particular, to the effect of blurring and/or fragmenting. The devices and methods provide improved resistance to the effects of such errors by decoupling the image generating interval from the reporting interval. Specifically, the devices and methods enable the determination of the reporting rate independently of the period over which images of sensor values are generated. The devices and methods enable independent determination of the reporting rate by facilitating the setting of a second period, where images of sensor values are generated over a first period and the reporting interval is determined to include at least the sum of the first period and the second period.
