The present invention relates to fields of medical technology and camera-based vital signs monitoring using remote photoplethysmography (rPPG). A Device (10) for determining a physiological parameter of a subject (20) is presented, the device comprising: an interface (11) for receiving image data of a scene, said image data comprising a time-sequence of image frames; and a processor (12) for processing said image data, wherein the processor is configured to perform the steps of: determining, for each of said image frames, a first statistical parameter value indicative of a statistical dispersion of pixel values of said image frame (202); concatenating said first statistical parameter values over time based on the time-sequence of the corresponding image frames to obtain a first candidate signal (203); extracting a physiological parameter of the subject based on said first candidate signal (204). The present invention further relates to a corresponding system (1) and method (200).
