1. A digital image acquisition device, comprising:

  • an imaging optic and detector for acquiring an image;

    a first speed-optimized red eye filter for producing a first set of candidate red-eye regions for the acquired image;

    an image encoder for encoding said acquired imagea display; and

    a first image correction module for correcting one or more of said first set of candidate red eye regions in the acquired image to produce a first speed-optimized corrected acquired image;

    a second analysis-optimized filter configured to produce a second set of candidate red-eye regions for the acquired image, wherein the second analysis-optimized filter is configured to operate on regions of said array identified as corresponding to regions of said first speed-optimized set of candidate red eye regions, and wherein the second analysis optimized filter is configured to provide a falsing analysis of said regions;

    a second image correction module for correcting a second set of candidate red eye regions in the acquired image, different than said first set, to produce a second analysis-optimized corrected acquired image; and

    an image store memory for storing therein one or more images each including a header and a main image body, said header comprising said acquired image or said first speed-optimized corrected acquired image, or both, and said main image body comprising said acquired image, said first speed-optimized corrected acquired image, or said second analysis-optimized corrected acquired image.
