  • Physiology measurement device and system, and operating method of wireless single chip
    Patent number: 9517019
    Abstract: There is provided a physiological measurement device including a light source, an image sensor and a processor. The light source illuminates a skin surface with a first brightness value and a second brightness value. The image sensor receives scattered light from tissues below the skin surface, and outputs a first image frame corresponding to the first brightness value and a second image frame corresponding to the second brightness value. The processor calculates an intensity comparison index between the first image frame and the second image frame, calculates perfusion data according to the first image frame and/or the second image frame, and identifies a contact status according to the intensity comparison index.
