Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for modifying one or more parameters of graphical overlays to increase readability when arranged over a very visually noisy display screen. An example embodiment operates by determining a graphic rendering area and position within a video frame of a graphical overlay, calculating a location of video sub-blocks located in another layer of the video frame and aligned with the graphic rendering area and position, wherein the video sub-blocks at least partially obfuscate the graphical overlay during rendering, evaluating a histogram of the video sub-blocks aligned with the graphic rendering area and position and increasing, based on the histogram, an opacity of the graphical overlay, and whereby the video frame can be rendered on a display screen.
