摘要： An iris recognition system may include an optical system having an intentional amount of spherical aberration that results in an extended depth of field. A raw image of an iris captured by the optical system may be normalized. In some embodiments, the normalized raw image may be processed to enhance the MTF of the normalized iris image. An iris code may be generated from the normalized raw image or the enhanced normalized raw image. The iris code may be compared to known iris codes to determine if there is a match.

An estimating unit configured to estimate cyclic noise components included in each image picked up under different exposure conditions for each image is included. The estimating unit estimates the cyclic noise components for each image through operation utilizing mutual relationship between the noise components under the exposure conditions. For example, the cyclic noise is flicker. The mutual relationship between the noise components may be expressed with a shutter function of the exposure conditions in frequency space.
