Claim Text:
1. A device for determining a vital sign of a subject comprising: an interface configured to receive a data stream derived from detected electromagnetic radiation reflected from a region of interest including a plurality of skin areas of the subject irradiated by ambient light, said data stream comprising a data signal per skin pixel area of one or more skin pixels for each of the plurality of skin areas of said region of interest, a data signal representing the detected electromagnetic radiation reflected from the respective skin pixel area over time, an analyzer configured to analyze spatial and optical properties of the data signals in a plurality of wavelength ranges, a processor configured to differentiate between a vital sign information signal of the subject and background noise based on the data signals of skin pixel areas within the plurality of skin areas, and a post-processor configured to determine the desired vital sign from said vital sign information signal.
