Abstract
Systems and methods are provided for analyzing conditions associated with a physical feature using digital images. The method comprises acquiring a white-light image and an ultraviolet (“UV”) image of at least a portion of a body surface, such as a person's face, each of the white-light and UV images including a plurality of pixels and each pixel in the UV image corresponding to a respective pixel in the white-light image. The method further comprises identifying feature pixels in the white-light and UV images, and obtaining results associated with at least one physical condition using information in the feature pixels in the first white light and UV images.
Claims39
A system for analyzing physical conditions associated with a subject, comprising:
- an image acquisition device including:
- an optical assembly comprising a lens;
- a source light shield extending outwardly from the lens;
- UV light source for illuminating the subject;
- and
- white light source comprising a ring-shaped configuration for illuminating the subject, wherein the while light source is positioned behind the source light shield,
- said device configured to acquire a white-light image and a UV image of a physical feature of the subject, each of the white-light and UV images having a plurality of pixels, each pixel in the UV image corresponding to a respective pixel in the white-light image;
- a computer system configured to obtain results associated with at least one physical condition using information in the pixels in the white light and UV images.

A method for analyzing at least one condition associated with a physical feature of a subject, comprising:
- acquiring a white-light image and a UV image of the physical feature of the subject via an image acquisition device including:
- an optical assembly comprising a lens;
- a source light shield extending outwardly from the lens of the optical assembly;
- a UV light source for illuminating the subject;
- and
- a white light source comprising a ring-shaped configuration for illuminating the subject, wherein the while light source is positioned behind the source light shield,
- said each of the white-light and UV images include a plurality of pixels, each pixel in the UV image corresponding to a respective pixel in the white-light image;
- examining properties of each pixel in at least the first white-light image to obtaining results associated with at least one condition using information in the pixels in at least one of the white-light and UV images.
