A method for modifying a video stream for display includes receiving a request to display a video stream in a display mode that facilitates viewing by visually impaired viewers. An unmodified region of interest (ROI) is identified in a current video frame of the video stream. A location of the unmodified ROI is tracked in each of the subsequent video frames. The unmodified ROI is magnified by a prescribed amount in at least some of the video frames in which the unmodified ROI is being tracked to produce a magnified ROI. For each of the video frames in which the unmodified ROI is being tracked and magnified, the magnified ROI is combined with at least a portion of the video frame in which the ROI is located to thereby produce a modified video stream.
