Abstract
An exemplary method of imaging tissue of a subject using a rolling shutter imager to provide a video stream comprises: sequentially resetting a plurality of rows of pixels of the rolling shutter imager from a first row to a last row; transitioning a liquid crystal shutter from a closed state to an open state; after the liquid crystal shutter is transitioned into the open state and after resetting the last row, illuminating the tissue of the subject with an illumination light for an illumination period to accumulate charge at the plurality of rows of pixels, and after the illumination period ends, sequentially reading the accumulated charge at the rows of pixels from the first row to the last row; generating an image frame from the sequentially read accumulated charge at the plurality of rows of pixels; and adding the image frame to the video stream.
