New addition! 01.03.31
1976: Hitachi FP-3030B Single Tube Color
Camera.
.
This is one of the very
first single vidicon portable color cameras. This camera is rather small
by standards of the day and also produced a very high quality color picture
for a single tube system. It has a seperate 1-1/2" B/W viefinder and either
an internal battery pack or sync generator pack. Full color balance controls
are available on the back panel.
The FP-3030 uses a single
1" RGB striped target vidicon. That is to to say that the picture is divided
inot fine vertical lines of Red, Green and Blue. These signals are routed
to a circuit called the Color Matrix which translates them into three new
signals called Y, V & U. The Y signal is essentially the same as an
original black and white video signal. It conveys the brightness information
contained in the televised scene. The V and U signals are made by subtracting
the Red and Blue signals from the Y signal. This has two effects. One is
to reduce the energy contained in them and the second is to remove the
part of the color signal that is redundant with the brightness. There is
no reason to send the same information more than once. That would be inefficient.
By doing this magic with
the color signals, it became possible for B/W televisions to recieve color
broadcasts and form normal B/W pictures. Likewise, a color TV can recieve
a B/W broadcast and make a normal B/W picture as well as a color picture
during color transmission.
