Black balance

Video cameras can possess a function called black balance which calibrates the signal for no light, just as they have a "white balance" function which gives reference to true white to the CCDs. Unlike white balance, black balance is not adjusted every time. This function is found in higher end 'professional' cameras rather than in cameras for amateurs.
