Abstract: A method for photoplethysmography measurement couples a color camera in optical contact against a skin surface of a subject and couples at least a first solid-state illumination source in optical contact against the skin surface, wherein the first solid-state illumination source has a first wavelength range with a first bandwidth that exceeds 50 nm. The illumination source and color camera are energized over a predetermined time interval to acquire a first sequence of image frames from the skin surface. A set of hue values is computed from each of the acquired sequence of image frames and photoplethysmography data generated according to periodic changes in an average hue per frame computation. The generated photoplethysmography data is presented on a display.
