automatic black balance (video) (ABB)

In classic analog video technology, automatic black balance was a color correction technique used to reduce color deviations. This technique was called Automatic Black Balance (ABB).

The color channels for red, green and blue are matched to each other so that black image details are not recorded with a color cast when recording with video cameras. This adjustment, which takes place with the aperture closed, is called Automatic Black Balance (ABB). Like white balance, black balance can be performed automatically or manually. The color components of the three primary colors are adjusted so that the sum signal is color-neutral.
