Abstract
A system for capturing and analyzing images of body features to identify treatments has a base unit with a processor and a display and an image management software component for presenting on the display a user interface to prompt a user to capture images in preselected locations on a body and to receive captured image data. The system has at least two light sources under control of the user interface that provide light following first and second light paths from the respective light sources to the plane of an imaging station, each light path having a significant portion of its light on the plane of the imaging station at a grazing angle of about ten to about thirty degrees. The first and second light paths when projected onto the plane of the imaging station intersect at an angle of at least sixty degrees. An image sensor receives light from the light sources that is reflected from the surface of a body feature located at the imaging station and produces pixel image data representing the body feature. A rating software component receives the pixel image data from the image sensor and is configured to mimic the judgment of a dermatologist to provide a rating vector representing the…
