Abstract
A device for obtaining vital sign information of a living being comprises a detection unit that receives light in at least one wavelength interval reflected from at least a region of interest of a living being and that generates an input signal from the received light. A processing unit processes the input signal and derives vital sign information of the living being from the input signal by use of remote photoplethysmography. An illumination unit illuminates at least the region of interest with light, and a control unit controls the illumination unit based on the input signal and/or the derived vital sign information.
