  • Patent number: 10932649
    Abstract: A system may control an illuminator to illuminate a surgical site with non-white light and control a camera to capture light reflected from the surgical site. The camera may separate the captured light into a plurality of color components. The plurality of color components may be captured by the camera as a plurality of sets of pixels of a frame in a video stream, and each set of the plurality of sets of pixels may be in a different color channel of the camera. The system may further control, based on color component characteristics of the light captured by the camera, the illuminator to configure the non-white light such that each color channel of the camera has an about equal response to the light captured by the camera for a subsequently captured frame in the video stream.
