April 24, 2015 Views:223



BLC (Backlight Compensation) compensates for the luminance of video captured in a backlit environment, while maintaining the luminance of the overall video sequence. Simply put, BLC enables objects that appear dark to be visible against a very bright background such as in front of a window or entrance. BLC is usually effective for some specific region in the video, as the background is usually overexposed.
