1. A system, comprising one or more integrated circuits, wherein the one or more integrated circuits include:

  • extraction logic configured to calculate a brightness metric associated with received video image data corresponding to at least one video image;

    analysis logic configured to analyze the brightness metric to identify a first subset of the video image and a second subset of the video image, wherein the first subset of the video image includes spatially varying visual information in the video image and the second subset of the video image includes the remainder of the video image that does not include spatially varying visual information; and

    adjustment logic configured to adjust a brightness of the second subset of the video image independent from the first subset, wherein a new brightness of the second subset of the video image is greater than a minimum brightness for a display that is configured to display a visual representation of the video image data, wherein the new brightness provides additional headroom to attenuate noise associated with displaying a portion of the visual representation that corresponds to the second subset of the video image.
