The LEAD Video Auto Contrast filter changes the contrast without changing colors (hue). 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. The property page is shown in the figure below:
The Auto Contrast property page provides a user interface for changing the filter's attributes. Changes will be applied directly to the streaming media with the ability to set them permanently by selecting Apply or OK, or to abandon changes by selecting Cancel. Positioning the mouse pointer over a control displays general information for that control. The following table shows the controls and their descriptions:
