Abstract:
System and Method pertaining to the modification and integration of an existing consumer digital camera, for example, with an optical imaging module to enable point and shoot fundus photography of the eye. The auto-focus macro capability of existing consumer cameras is adapted to photograph the retina over an extended diopter range, eliminating the need for manual diopter focus adjustment. The thru-the-lens (TTL) auto-exposure flash capability of existing consumer cameras is adapted to photograph the retina with automatic flash exposure eliminating the need for manual flash adjustment. The consumer camera imaging sensor and flash are modified to allow the camera sensor to perform both non-mydriatic focusing of the retina using infrared illumination and standard color flash photography of the retina without the need for additional imaging sensors or mechanical filters. These modifications and integration of existing consumer cameras for fundus photography of the eye significantly improve ease of manufacture and usability.

Claim (Index 13):
A method to remove non-retinal ophthalmic reflection from at least one retinal image amongst a plurality of retinal images and to create a blended composite of the retinal images, the method comprising:\n obtaining information comprising a plurality retinal images of a subject from a camera device; identifying a non-retinal ophthalmic reflection in at least one image amongst the plurality of retinal images by automatically determining differences in the optical properties of the non-retinal ophthalmic reflection compared to the optical properties of the retinal image that do not contain the non-retinal ophthalmic reflection; using the identified non-retinal ophthalmic reflection, automatically constructing a digital representation of a mask that corresponds to areas of the retinal image containing the non-retinal ophthalmic reflection; removing the non-retinal ophthalmic reflection by digitally applying the mask to the retinal image to provide a digitally-masked retinal image; aggregating the retinal images including the digitally-masked retinal image to generate a composite for presentation to a user.
