Glossary

Black set
Black set means that the R, G and B signals of a video
signal are set to the memorized level to obtain the
definite black level for each R, G and B signals. When
the black set is adjusted, the black picture can be
avoided from being colored by raising the signal level.
Black balance
Black balance means to set the black level of a video
signal to that of no color when the iris is closed.
Adjust the pedestal level of each R, G or B signal so
that the signal level of each signal becomes equal.
Color temperature conversion filter
All color cameras are designed to operate on a certain
color temperature (3200K for the DXC-327B/327BP.)
However, the camera must also have the capability of
shooting under color temperatures other than 3200K.
To obtain the same color as at 3200K, a number of
selectable filters which convert color temperature are
provided on the camera.
Color temperature
The temperature to which a perfectly black body must
be heated to match the color of the source being
measured. Color temperature measurements are
expressed in kelvins (K). For example, color
temperature of 6500K means the color which is
obtained by heating a perfectly black body at 6500K.
E-E picture
The video signal input to the VTR passes through the
VTR amplifier and outputs through the video output
connector without being recorded onto the tape.
Phantom powering system
The power is supplied to a microphone overlaid on an
audio signal. This system does not require an optional
cable for supplying power.

Return video
The "return video" is the picture from a VTR during
recording, the playback picture during playback, or the
signal from a control console such as a video switcher.
Using this picture, the camera operator can check the
recording conditions.
Subcarrier
Color information that is contained within a composite
video signal. The signal amplitude is for color
saturation (chromaticity) and its phase to color burst is
for hue (color).
S-video input connector
This connector accepts and supplies the luminance and
chrominance signals separately. So no interference
occurs between the luminance and chrominance
signals which allows high resolution pictures.
White balance
The variation of color temperature due to the type of
illuminant must be compensated electrically so that a
white object picked up by a camera can been seen as
clear white. This is white balance adjustment.
