1. A method for use in a retinal image capturing system comprising:
- determining whether an individual is within a predetermined distance of the system;
automatically capturing an image of at least a portion of the individual'"'"'s retina in response to a determination that the individual is within a predetermined distance of the system;
determining whether the captured image is sufficient to provide identification data; and
capturing another image of the retina if a captured image is determined to be insufficient.

Abstract
A method and system capture an image of the interior of the eye, for example the retina and determine whether the captured image is sufficient to provide data for identifying an individual or animal before attempting to generate the identification data. If the captured image is not sufficient, the method and system automatically capture another image of the interior of the eye.

51. A system for automatically capturing an image of a retina comprising:
-
a proximity detector for detecting the proximity of an individual to the system;
an image capturing device for capturing an image of a retina;
a processor responsive to the proximity detector to control the image capturing device to capture an image of the retina, the processor determining the sufficiency of a captured image to provide identification data and if the processor determines that the image is not sufficient, the processor controlling the image capturing device to capture another image of the retina.
