Claim One:
1. Within an image acquisition system comprising a non-linear, wide-angled lens and an imaging sensor, a method of enhancing a scene containing one or more off-center peripheral regions, the method comprising: acquiring an initial distorted image with a large field of view, including using a non-linear, wide-angled lens and imaging sensor; determining and extracting an off-center region of interest (hereinafter “ROI”) within said image; applying geometric correction to reconstruct the off-center ROI into an approximately rectangular frame of reference as a reconstructed ROI; determining a quality of reconstructed pixels within said reconstructed ROI; applying face detecting or tracking, or both, to one or more regions within the reconstructed ROI respectively adapted to one or more local reconstructed pixel qualities within the one or more regions; determining a parameter of a face within the reconstructed ROI; and performing a further action based on a value of the parameter of the face within the reconstructed ROI.
