Abstract
The present invention relates to a device and a method for extracting physiological information indicative of at least one health symptom from remotely detected electromagnetic radiation. The device comprises an interface (20) for receiving a data stream comprising remotely detected image data representing an observed region comprising at least one subject of interest (12), wherein the image data comprises wavelength-dependent image information, wherein the wavelength-dependent image information is composed of at least two color channels (96, 98, 100) representative of respective wavelength portions; an image processor (22) for detecting channel signal strength information for at least two of the at least two color channels (96, 98, 100); and a data comparison unit(24) for comparing detected channel signal strengths with respective reference values.
