1. A method for modifying a display source light illumination level, said method comprising:

  • a) determining a relative source light parameter representing the relative amount that a source light level can be reduced with adequate compensation through brightness preservation processing, where said brightness preservation processing is based upon an effectiveness of brightness preservation process that is based upon the content of an input image;

    b) determining a display power difference value;

    c) determining a previous frame peak source light illumination level; and

    d) modifying said previous frame peak source light illumination level with said relative source light parameter and said display power difference value, thereby creating a current-frame modified source light illumination level.
