Abstract: Biometric detection of a fingerprint is provided by a flexible sensor, in which one or more positioning members move at least a portion of the sensor to conform to a shape of a finger disposed along the sensor to enable capture of a rolled-equivalent fingerprint for the finger. Such one or more positioning members move the sensor causing it to curl at least along a region extending between right and left sides of a fingernail of the finger around a front of the finger in order to conform the sensor to the finger so that the sensing elements of the sensor when enabled capture images of the rolled-equivalent fingerprints without rotation or rocking of the finger with respect to the sensor. When sensing elements are optically sensitive, one or more light sources may provide light to illuminate the finger when the sensor captures rolled-equivalent fingerprint images.

Abstract: A sensor for capturing images of skin topology is provided having a platen, and a one or two-dimensional array of light sensing pixel elements for receiving light representative of skin topology when skin, such as finger(s), are present upon the platen. Such sensor being improved by structures, layers, or methods for reducing or blocking ambient light which would hinder the light sensing pixel elements from sensing the light representative of skin topology. The sensors are non-imaging contact sensors as they have platen to contact skin to be imaged, and do not require optics, such as lenses for focusing and/or magnification, to enable proper capture of light representative of skin topology on the sensor's light sensing pixel elements.

The pixel elements are sensitive to one or more selected wavelengths or wavelength ranges of the ambient light present. Optional light source(s) may be provided for use when ambient light present is inadequate for proper sensor operation.

Abstract: The invention provides an image capture system, apparatus and method for capturing a biometric image in high ambient light environments. Reflections from ambient light can introduce unwanted environmental pattern noise that can interfere with extracting information from a captured biometric image. The invention performs attenuation of ambient light without requiring employment of shielding to prevent ambient light from reflecting off of a surface being imaged. As a result, the invention can be deployed into environments with varied indoor or outdoor lighting characteristics.

At least one processor (27) which determines for each of the images captured a difference in height of at least one characteristic of the fingers in the image. Using said difference in height of the fingers in each of the images, the processor (27) verifies that the correct sequence of specific ones of finger pair was provided by the subject to the platen when images were captured. Fingerprint images acquired from the images may be stored in an electronic record along with thumb prints and subject information, and optionally the height differences for the images.

Abstract: A system and method of capturing an acceptable fingerprint image is disclosed herein. The method includes a step of capturing an initial fingerprint image at a nominal image integration time. Once this initial fingerprint image is captured, a first intermediate fingerprint image at a first intermediate image integration time is captured. Next, an image darkness test is performed followed by an image definition test. If one or more of these tests indicates that the first intermediate fingerprint image is unacceptable, a subsequent intermediate fingerprint image at a subsequent intermediate image integration time is captured. This subsequent intermediate fingerprint image can be captured before the image definition test is performed. Additional intermediate fingerprint images can be captured until an image that has an acceptable darkness level as a well as an acceptable definition level is captured. Also disclosed is a fingerprint scanner that performs this method.
