Abstract
The present invention relates to a device, system and method for improved non-invasive and objective detection of pulse of a subject. The device comprises an input unit (2a) configured to obtain a series of images of a skin region of the subject and a processing unit (2b) for processing said series of images by detecting pulse-related motion of the skin within the skin region from the series of images, generating a motion map of the skin region from the detected pulse-related motion, comparing the generated motion map with an expected motion map of the skin region, and determining the presence of pulse within the skin region based on the comparison.
