Abstract: In a system and method for determining vital sign information of a subject the subject is illuminated with radiation, and radiation reflected from the subject is received. A region of interest is located in a first phase. Said illumination is controlled to locally illuminate, in a second phase, the located region of interest with radiation allowing determination of vital sign information. Finally, vital sign information of the subject is determined from the radiation reflected from said region of interest and detected in said second phase.
