1. A portable digital image acquisition device, comprising:

  • (a) at least one lens and at least one sensor for acquiring a main digital image and first and second reference images of approximately a same acquired scene that includes one or more luminous objects;

    (b) a memory for storing the main digital image;

    (c) one or more non-transitory processor-readable media having digital code embedded therein for programming a processor to perform a method of determining an iris region of an eye in the main digital image using the first and second reference images, wherein the method comprises;

    (i) acquiring the first and second reference images using the at least one lens and the at least one sensor;

    (ii) normalizing the first and second 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 the iris region of the eye within the main image based on the analyzing;

    (v) generating meta data based on the determining of the iris region; and

    (vi) storing, transmitting, communicating, displaying, or projecting the main image or a further processed version, or combinations thereof, along with said meta data.
