Learning Event 1:
DESCRIBE HOW THE COLOR SEPARATION SYSTEM WORKS IN A COLOR CAMERA
1.
The block diagram, shown in figure 3-1, shows the major components of
the complete color camera chain and their relationship to the units of the
camera. Red, green and blue video outputs from the camera are fed through
the camera cable to the remote camera control panel and processing
amplifier.
a. The processing amplifier and control panel, which can be compared to
the camera control in a monochrome system, inserts blanking, shading, and
pedestal control for the three tubes, and performs other functions described
late in this section. From the processing amplifiers, red, green, and blue
video signals are encoded into the composite output color signals.
b. A monitoring console provides both picture tube and waveform
displays of various other points in the system which can be selected for
display by a switching system. A color monitor provides a composite color
picture of the encoded signal.
