Device and method for obtaining vital sign information of a living being
First Claim
1. A device for obtaining a sign information of a living being, comprising:
- 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 that processes the input signal and derives vital sign information of said living being from said input signal by use of remote photoplethysmography,an illumination unit that illuminates at least said region of interest with light, anda control unit that controls said illumination unit based on said input signal and/or said derived vital sign information.

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 said living being from said input signal by use of remote photoplethysmography. An illumination unit illuminates at least said region of interest with light, and a control unit controls said illumination unit based on said input signal and/or said derived vital sign information.

15. A method for obtaining vital sign information of a living being, comprising:
-
illuminating at least a region of interest of a living being with light, receiving light in at least one wavelength interval reflected from at least said region of interest, generating an input signal from the received light, processing the input signal and deriving vital sign information of said living being from said input signal by use of remote photoplethysmography, and controlling said illumination unit based on said input signal and/or said derived vital sign information.
