LEAD Video Auto Contrast Filter

The LEAD Video Auto Contrast filter performs color leveling at the luminance (grayscale) level, introducing no color cast. It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream. It also maximizes the tonal range of the image and enhances the contrast and intensity using the image's histogram and a color distribution-based algorithm.
