Abstract
A vital sign detection system comprises a camera () configured to acquire image frames from an examination zone (). A signal processor () derives vital sign information from the acquired image frames. An illumination controller () controls illumination of the examination zone, generates temporal modulations of the illumination and synchronise the camera frame rate with the modulated illumination. The vital sign detection system of the invention achieves to increase the dynamic range and hence also the signal-to-noise ratio of the vital sign signal.
