Terminal device, sensing method and apparatus with sensor for fingerprint identification

摘要

A terminal device, a sensing method, and a sensing apparatus are provided. The terminal device include a plurality of optical sensors, wherein the plurality of optical sensors are arranged in a plurality of sub-regions, and each of the plurality of sub-regions has a respective optical parameter; and a processor, configured to: control the optical sensor in each sub-region to, upon detecting a target object, sense the target object with a first optical parameter value, and obtain a first sensing signal in each sub-region; determine a target signal range according to the first sensing signal in each sub-region; determine a second optical parameter value with respect to each sub-region according to the first sensing signal in the sub-region and the target signal range; and set the optical parameter of each sub-region to the second optical parameter value.
