Abstract
A fingerprint recognition system in which a user's finger is scanned over a strip sensor until it is determined that sufficient image data samples have been obtained, then an indication is provided that the scanning operation is complete.
Claims16
A method for detecting biometric information in respect of a user, the method comprising acts of:
- acquiring by at least one sensor a sample of low resolution image data of a plurality of regions that together make up a unique area of a user body part;
- identifying whether the acquired low resolution image data is sufficient to construct a high resolution image in each of the plurality of regions of the unique area;
- and
- acquiring one or more further samples of low resolution image data of a given one of the plurality of regions when it is identified that the low resolution image data of the given one the plurality of regions is not sufficient to construct the high resolution image.

A system for detecting biometric information in respect of a user, the system comprising:
- at least one sensor for acquiring a sample of low resolution image data representative of the structure of a plurality of regions that together make up a unique area of a user body part when said body part is passed over said sensor;
- and
- a processor configured to
- identify whether the acquired low resolution image data is sufficient to construct a high resolution image in each of the plurality of regions of the unique area, and
- acquire one or more further samples of low resolution image data of a given one of the plurality of regions when it is identified that the low resolution image data of the given one of the plurality of regions is not sufficient to construct the high resolution image.

A method for detecting biometric information in respect of a user, the method comprising acts of:
- acquiring by at least one sensor a sample of low resolution image data representative of a plurality of regions that together make up a structure of a unique area of a user body part;
- generating data representative of at least one sub-surface parameter in respect of the body part;
- identifying whether the acquired low resolution image data is sufficient to construct a high resolution image in each of the plurality of regions representative of the structure of the unique area;
- acquiring one or more further samples of low resolution image data of a given one of the plurality of regions when it is identified that the low resolution image data of the given one of the plurality of regions is not sufficient to construct the high resolution image;
- performing user identification using in combination the high resolution image and the image data representative of at least one sub-surface parameter.
