black level

The intensity of black in a TV picture -- frequently referred to as brightness -- adjusted to compensate for ambient room light. Black level is set with a TV's brightness control using a PLUGE test pattern. Setting black level correctly is critical to overall picture quality, particularly the ability to see detail in dimly lit scenes of a film. The term also refers to the ability of a display to produce an inky, deep black, which is often a problem in fixed-pixel displays.
