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.
Receiver/Display Controller
Power Requirements ........................... 100/115/230 VAC, 50/60 Hz

(92mm x 191mm x 241mm)
Operating Temperature Range ............ 32 to 104° F (0 to 40° C)
Relative Humidity ................................ 95%
Video Input ........................................... Combined Pyrometer/Video from
camera on BNC connector
Video Output ........................................ Composite on BNC connector
Color Video Output .............................. Analog RGB on 9-pin D-type
Weight ................................................. 4.75 lbs. (2.15 kg)
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.
