Imaging system and method for physical feature analysis
First Claim
1. An illumination system for use in capturing digital images of body features, where the images represent a plurality of views selected to reveal a condition of three or more attributes of those features, comprising:
- a first light source;
a light baffle for receiving at an entry of a first channel light flux from the first light source;
a first reflector element associated with the first channel for receiving light from the first light source and redirecting it to the plane of an imaging station at a grazing angle of ten to thirty degrees;
a second light source, the light baffle receiving at an entry of a second channel the light flux from the second light source; and
a second reflector element associated with the second channel for receiving light from the second light source and redirecting to the plane of the imaging station at a grazing angle of ten to thirty degrees;
whereinthe first light source, light baffle and first reflector element are configured so that the imaging station receives from the first light source substantially only a flux of light that has been reflected by the first reflector element; and
whereinthe second light source, light baffle and second reflector element are configured so that the imaging station receives from the second light source substantially only a flux of light that has been reflected by the second reflector element.

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 condition of three or more attributes of the body feature represented by the pixel image data.

35. A method for scoring a multidimensional body feature analysis for a subject, comprising using a processor to perform the steps of;
-
receiving a set of scores Ni derived from image data and representing the condition of the subject'"'"'s body feature as to three or more attributes (i); defining for a set of three or more treatment products (p) and for each of the three or more attributes a set of scoring weights Wip; computing for each set of three or more treatment products a product-adjusted set of scores ANip, by applying the scoring weights Wip for each treatment product to the set of scores Ni for the three or more attributes; mapping each of the possible scores Ni for each of the three or more attributes into a value on a rating scale ranging across at least three possible values Ci; building a table for product recommendations, by associating with at least a plurality of the possible combinations of values on the rating scale a recommendation identifying one of the three or more treatment products; and mapping the scores Ni of the subject into a set of values {C1, C2, C3 . . . } for the three or more attributes and finding the corresponding product recommendation in the table for product recommendations. - View Dependent Claims (36, 37, 38, 39, 40, 41)
