remote photoplethysmographic monitoring system and method for extracting physiological information indicative of at least one health symptom from remotely detected electromagnetic radiation, and computer program

摘要

The present invention relates to a device and 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 detected image data representing an observed region comprising at least one subject (12), the image data comprising wavelength dependent image information wherein the wavelength dependent image information is composed of at least two color channels (96, 98, 100) representative of the respective wavelength portions; an image processor (22) for detecting channel signal strength information from at least two of at least two color channels (96, 98, 100); and a data comparison unit (24) for comparing detected channel signal strengths with respective reference values.
