The present invention relates to a device and a method for determining a vital sign of a subject. The proposed device comprises an interface (32) for receiving a data stream (26) derived from detected electromagnetic radiation (16) reflected from a region of interest including a skin area of the subject (12), said data stream (26) comprising a data signal per skin pixel area of one or more skin pixels for a plurality of skin pixel areas of said region of interest, a data signal representing the detected electromagnetic radiation (16) reflected from the respective skin pixel area over time, an analyzer (34) for analyzing spatial and/or temporal properties of the skin area, a processor (36) for determining a vital sign information signal of the subject based on the data signals of skin pixel areas within the skin area, and a post-processor (38) for determining the desired vital sign from said vital sign information signal, wherein said determined spatial and/or temporal properties are used by the processor for determining the vital sign information signal and/or by the post-processor for determining the desired vital sign. |
