Meaning of BLACK LEVEL in English


strictly interpreted, denotes the light level at which a video signal representing picture black is reproduced on your TV screen. You probably already know that in terms of light output from a TV set black areas of the picture should be represented by an absence of light. Something that is black or below black in the video signal shouldn't produce any visible light from the display. VE T9-11.Some TV sets actually use Black Level as a control name. It is a far better description of the function of that control than the most commonly found name for it, which is Brightness.
