SPECIFICATIOnS AnD PErFOrMAnCE
Figure A shows a typical video signal. The distance
between the white level (at the top) and the black level
(at the bottom) is the total range of contrast available.
Figure B shows that by dropping the black level, the
distance between the white and black levels gets bigger,
increasing the contrast range. By lowering the black
level the darker objects get darker without changing
the white ones. Likewise is true when the white level is
raised, the white objects get whiter without changing the
dark ones.
Shading correction is accomplished by applying
sawtooth and parabolic correction signals to the video
signal.
For example, when the video signal is combined with
the horizontal sawtooth signal, one side or the other of
the picture gets lighter while the other side darkens. The
horizontal parabolic signal lightens or darkens only the
edges of the picture. The vertical controls do the same
thing as the horizontal, only from top to bottom.
