Peak dark detection (PDD) top border, bottom border, left border, right border:
These four control items define the picture area insides the peak dark detector
is enabled. The peak dark detector is storing the lowest level of the luminance
signal. If this value is higher than the clamping level the luminance signal is
stretched towards clamping level (Black stretch function). Those parts of the
picture with a luminance signal less than 50% of nominal amplitude are get-
ting more dark.
It is possible with these four control items to screen black borders of the pic-
ture (e.g. letter box format) which otherwise prevent the desired function of
black stretch.
The following figure and table show their definitions:
