The embodiments described herein provide devices and methods that facilitate improved input device performance. Specifically, the devices and methods provide improved resistance to the effect of interference on input devices, and in particular, to the effect of unison noise on proximity sensors that use capacitive techniques to generate images of sensor values. The devices and methods provide improved resistance to the effects of interface by using multiple images of sensor values, where the multiple images of sensor values are captured at different times along two different axes. The multiple images of sensor values are combined to produce a modified image of sensor values, the modified image having reduced errors due to noise. This reduction in errors due to noise can improve the accuracy and performance of the input device. |
