1. A portable digital image acquisition device, comprising:
- (a) a lens and a sensor for acquiring a main digital image and first and second reference images;
(b) first and second light sources disposed at different distances from the lens for illuminating one or more objects within an acquired scene;
(c) a memory for storing the main digital image;
(d) one or more processor-readable media having digital code embedded therein for programming a processor to perform a method of determining and correcting a flash eye defect in the main digital image using the first and second reference images, wherein the method comprises;
(i) acquiring the first and second reference images respectively using the first and second light sources;
(ii) normalizing the first and second reference images to generate normalized first and second reference images;
(iii) analyzing one or more differences between the first and second normalized reference images;
(iv) determining and correcting the flash eye defect within the main image based on the analyzing to generate a corrected main image; and
(v) storing, transmitting, communicating, displaying, or projecting the corrected main image or a further processed version, or combinations thereof.

Abstract
A portable digital image acquisition device includes multiple lenses and/or multiple flashes. A main digital image and first and second reference images are acquired. The first and second reference images are acquired with different flash-lens combinations that have different flash-lens distances. One or more flash eye defects are detected and corrected in the main image based on analysis of the first and second reference images.
