Abstract
An electronic device may include a finger biometric sensor that includes an array of electric field sensing pixels and image data output circuitry coupled thereto and capable of outputting image data from a plurality of sub-arrays of the array of electric field sensing pixels and processing circuitry coupled to the image data output circuitry. The processing circuitry is capable of determining movement of a user's finger across the array of electric field sensing pixels by comparing image data from borders of adjacent sub-arrays, the movement causing artifacts in the image data, and, when movement of the user's finger is determined, remove the artifacts from the image data.
