摘要

summary device for obtaining vital sign information from a living being; and method of obtaining vital sign information from a living being The present invention relates to a device (1) and method of obtaining vital sign information from a living being (2). the proposed device (1) comprises a sensing unit (3) for receiving light (4) at least one wavelength range reflected in at least one region of interest (20) of a living being (2) and generating a input signal (5) from the received light (4), a processing unit (6) for processing the input signal (5) and providing the vital sign information (7) of said living being from said signal (5) using remote photoplethysmography and a lighting unit (8) to illuminate said at least one region of interest (20) during light illumination intervals, wherein said light during said illumination intervals predominates ambient light at least in the wavelength range in which the sensing unit (3) receives light (4) and is thus optimized to provide vital signal information from an input signal generated using remote photoplethysmography a pa from incoming light reflected in the said region of interest.
