Abstract
An electronic device may include finger biometric sensing pixels and a processor capable of cooperating with the finger biometric sensing pixels to generate a series of finger images at a progressively slower capture rate as a finger settling increases over time from initial placement of a user's finger adjacent the finger biometric sensing pixels. The processor may also be capable of cooperating with the finger biometric sensing pixels to determine a quality factor for each image in the series thereof, and select at least one image from the series thereof for matching and based upon the quality factor.
Claims30
An electronic device comprising:
- a plurality of finger biometric sensing pixels;
- and
- a processor arranged to cooperate with the plurality of finger biometric sensing pixels to
- generate a series of finger images at a progressively slower rate as finger settling increases over time during static placement of a user's finger adjacent the plurality of finger biometric sensing pixels,
- determine a quality factor for each image in the series thereof, and
- select at least one image from the series thereof for matching for authentication and based upon the quality factor.
An electronic device comprising:
- a housing;
- a finger operated user input device carried by the housing;
- a plurality of finger biometric sensing pixels carried by the finger operated user input device;
- and
- a processor carried by the housing and arranged to cooperate with the plurality of finger biometric sensing pixels to
- generate a series of finger images at a progressively slower rate as a finger settling increases over time during static placement of a user's finger adjacent the plurality of finger biometric sensing pixels,
- determine a quality factor for each image in the series thereof, and
- select at least one image from the series thereof for matching for authentication and based upon the quality factor.
A method of matching a finger biometric using an electronic device that includes a plurality of finger biometric sensing pixels and a processor capable of cooperating with the plurality of finger biometric sensing pixels, the method comprising:
- using the processor to
- generate a series of finger images at a progressively slower rate as a finger settling increases over time during static placement of a user's finger adjacent the plurality of finger biometric sensing pixels,
- determine a quality factor for each image in the series thereof, and
- select at least one image from the series thereof for matching for authentication and based upon the quality factor.
