Claim Text:
1. An image processing system for obtaining biophysical information about a mammalian subject, said image processing system comprising: an image receiving unit, including at least one image sensor, configured to receive a video electronic color image of a first tissue of the mammalian subject, the electronic color image comprising spatial temporal per pixel information for a visible red color space, spatial temporal per pixel information for a visible green color space and spatial temporal per pixel information for a visible blue color space, the electronic color image derived from light reflected from and/or traversing the first tissue, the light incident from a light source and having a wavelength between near UV and near IR; and an image processing unit configured for (a) electronically processing said image by transforming per pixel information for the red, green and blue visible colors to transformed per pixel information for the red, green and blue visible colors, (b) using the transformed per pixel information of at least one of the red, green and blue visible colors to produce (i) a histogram of intensity for each color of the at least one of the red, green and blue visible colors or (ii) both a histogram of intensity for each color of the at least one of the red, green and blue visible colors and an averaging of spatial per pixel information for each color of the at least one of the red, green and blue visible colors, and (c) extracting measurement data from the (i) histogram or (ii) both the histogram and the averaging, to obtain the biophysical information using an iterative process, the image processing system adapted to obtain the biophysical information whether the incident light incident on the first tissue from the light source is filtered or unfiltered, continuous or discontinuous, of a natural light source or of an artificial light source.
