A video adjustment system for processing video information is disclosed which includes a motion analyzer and an adjustment module. The motion analyzer determines a motion level metric of the video information based on at least one motion parameter. The adjustment adjusts an initial dynamic light scaling factor to provide an adjusted dynamic light scaling factor based on the motion level. The dynamic light scaling factor may be used for luminance compensation and backlight display scaling. The motion level may be based on any type of motion information, such as motion vector information or information indicating a scene change. A distortion module may perform a distortion evaluation of the video information for calculating the initial scaling factor. Alternatively, the distortion module may include a memory which stores predetermined scaling factors based on statistical distortion level characterization.
