An embodiment of the invention provides a biological living body image monitoring system, and relates to the technical field of medical equipment. The biological living body image monitoring system comprises a display module, a processor and a CIGS chip, wherein the CIGS chip, the processor and the display module are electrically connected; the CIGS chip is used for detecting a near-infrared lightsignal of a biological living body, and generating a current signal after the near infrared light signal is detected; the processor is used for generating a first pulse signal according to the current signal; and the display module is used for carrying out image display according to the first pulse signal. The biological living body image monitoring system provided by the invention has the advantages that an image of subcutaneous blood vessels can be synchronously transmitted to the display module for display, and the image is clearer.
