Abstract
High quality, high contrast images of an iris and the face of a person are acquired in rapid succession in either sequence by a single sensor and one or more illuminators, preferably within less than one second of each other, by changing the data acquisition settings or illumination settings between each acquisition.
Claims20
A system for biometric acquisition, the system comprising:
- a depth measurement sensor configured to determine a distance of an image sensor from a subject;
- at least one light source;
- and
- the image sensor, the image sensor configured to:
- acquire, at a first time instant, an image of a first biometric feature of the subject, the first biometric feature illuminated by light of a first wavelength from the at least one light source set to a first intensity magnitude suitable for acquiring the image of the first biometric feature at the determined distance;
- and
- acquire, at a second time instant, an image of a second biometric feature of the subject, the second biometric feature illuminated by light of a second wavelength from the at least one light source set to a second intensity magnitude suitable for acquiring the image of the second biometric feature at the determined distance, wherein the second time instant is within a predetermined time period of the first time instant sufficient to link the image of the first biometric feature and the image of the second biometric feature to the same subject.
