PROXIMITY SENSING METHOD, PROXIMITY SENSING DEVICE, AND ELECTRONIC DEVICE THEREOF

摘要

An exemplary embodiment of the present disclosure illustrates a proximity sensing method used in a controller of a proximity sensing device. Firstly, a cross talk value is initialized. After the cross talk value is initialized, whether the cross talk value should be updated is judged at least according to a first sensing value currently received from a sensing unit of the proximity sensing device. When the cross talk value is judged to be updated, the cross talk value is updated at least according to a first sensing value. Then, a compensated sensing value is obtained by subtracting the cross talk value from the first sensing value.

1. A proximity sensing method, used in a controller of a proximity sensing device, comprising:
initializing a cross talk value; after the cross talk value is initialized, judging whether the cross talk value should be updated at least according to a first sensing value currently received from a sensing unit of the proximity sensing device; when that the cross talk value should be updated is judged, updating the cross talk value at least according to the first sensing value; and obtaining a compensated sensing value by subtracting the cross talk value from the first sensing value.
