MAX-ENTROPY CONTROL FOR HIGH QUALITY DIGITAL IMAGING
Phone: () -
Email: EREINERS@KESTRELCORP.COM
A low-cost, high-resolution, high-contrast color digital camera optimized
for ophthalmology will be demonstrated. The maximum entropy camera
will be tested for its effectiveness in meeting the image quality requirements
for telemedicine and for remote screening of pre-proliferative and
proliferative diabetic retinopathy. The proposed device exploits recent
technological advances in high sensitivity CCD cameras and digital signal
processing electronics. Today's low cost 8-bit CCD cameras do not have the
dynamic range to image the human retina, which is characterized by regions of
high reflectivity (20-40 percent), such as the optic disc, and very low
reflectivity (<2 percent), such as the macula and fovea. Existing digital
cameras used in ophthalmology are not designed to deal with the high dynamic
range and do not consider the special re-saturated characteristics of the
retina. The proposed device will be shown to offer significant improvement over
existing digital color cameras by addressing each of the deficiencies
mentioned.
