Method and apparatus for fingerprint image reconstruction
First Claim
1. A method for obtaining a biometric image, comprising:
- providing a biometric image sensor comprising one of a one dimensional swiped sensor array, a two dimensional swiped sensor array, and a two dimensional placement sensor array, the sensor array comprising a capacitive gap sensor measuring a change in a transmitted signal received as a received signal, wherein the measured change is based upon changes in the transmitted signal passing through a biometric in the vicinity of the sensor array, the biometric image sensor being one of mounted on a host device or cooperating with the host device;
estimating an angle of the biometric;
providing a biometric placement positioning prompt on a visual display device on the host device, the prompt indicating whether a current positioning of the biometric is proper, based on at least the angle of the biometric, for initiating biometric imaging by the biometric image sensor.
