Abstract:
1. A method of optimizing performance of a fingerprint sensor, the method comprising: creating a lookup table of optimal force ranges for initiating fingerprint acquisition in a plurality of different fingerprint sensors by testing the plurality of different fingerprint sensors at a plurality of force levels and performing at least one of an image quality analysis and a performance analysis to determine the optimal force range for each different fingerprint sensor; detecting placement of at least one finger on the fingerprint sensor; determining a force applied to the sensor by the at least one finger; determining an optimal force range for the fingerprint sensor by accessing the lookup table stored in a computer memory; determining whether the force is within the optimal force range for the fingerprint sensor; providing feedback to a user to adjust the applied force if the applied force is outside the optimal force range; and capturing at least one fingerprint image with the fingerprint sensor after the applied force is in the optimal force range.
