HYBRID CAPACITIVE BASELINE MANAGEMENT |
摘要 |
In a method of managing baselines of a capacitive sensing input device, a transcapacitive baseline, a first absolute capacitive baseline, and a second absolute capacitive baseline are acquired with a plurality of sensor electrodes of the capacitive sensing input device. A transcapacitive image, a first absolute capacitive profile, and a second absolute capacitive profile are acquired with the plurality of sensor electrodes. The transcapacitive baseline, the first absolute capacitive baseline, and the second absolute capacitive baseline are managed based on a value of at least one of the first absolute capacitive profile and the second absolute capacitive profile. |

1. A method of managing baselines of a capacitive sensing input device, said method comprising:
acquiring a transcapacitive baseline, a first absolute capacitive baseline, and a second absolute capacitive baseline with a plurality of sensor electrodes of the capacitive sensing input device; acquiring a transcapacitive image, a first absolute capacitive profile, and a second absolute capacitive profile with said plurality of sensor electrodes; and managing said transcapacitive baseline, said first absolute capacitive baseline, and said second absolute capacitive baseline based on a value of at least one of said first absolute capacitive profile and said second absolute capacitive profile. |
