The present invention relates to a device (1) and method for obtaining vital sign information of a living being (2). The proposed device (1) comprises a detection unit (3, 42, 61) for receiving light (4) in at least one wavelength interval reflected from at least a region of interest (20) of a living being (2) and for generating an input signal (5) from the received light (4), a processing unit (6) for processing the input signal (5) and deriving vital sign information (7) of said living being from said input signal (5) by use of remote photoplethysmography, an illumination unit (8, 43, 64) for illuminating at least said region of interest (20) with light, and a control unit (10) for controlling said illumination unit (8, 43, 64) based on said input signal (5) and/or said derived vital sign information (7).
