1. A method for establishing baseline data for a physiological monitoring system which captures images of an individual in order to monitor the well being of the individual, comprising; (a) operating a physiological monitoring system, including an image processor, a memory, and an image capture device, to automatically assess physiological conditions of a subject individual, where the physiological monitoring system is operated in a fixed capture area and the image capture device automatically acquires color images; (b) automatically acquiring color images of the individual using the image capture device during multiple image capture events; (c) automatically analyzing the color images using the image processor to identify an individual as a subject individual being monitored by the system, based on known personal data for the individual; (d) automatically analyzing the color images using the image processor to derive physiological data and image capture condition data, wherein the image capture condition data includes ambient lighting condition data; (e) automatically deriving baseline wellness parameter data for the subject individual, using the acquired physiological data and the image capture condition data; (f) automatically deriving target criteria for image capture, relative to the capture conditions, that apply during subsequent automatic image captures of the subject individual by the physiological monitoring system; and (g) automatically associating the derived baseline wellness parameter data, baseline capture condition data, and derived target criteria, for the subject individual with the individual's personal data, whereby baseline data is established for the physiological monitoring system for the subject individual.
