A filter that converts the color
temperature to a reference value so
the same picture tone is obtained in
different lighting conditions.

Composite video signal
A signal that consists of video
(luminance and color sub carrier),
sync (horizontal and vertical), and
color burst signals.

CTL
Abbreviation for control signal. A
signal that you can count to
determine the number of frames, and
therefore the tape's running time. It is
Abbreviation for control signal. A
signal that you can count to
determine the number of frames, and
therefore the tape's running time. It is
used mainly to adjust the tracking
position of video heads, and to
achieve time code continuity when
recording continuously. This signal is
recorded in a longitudinal tape track.

DCC
Abbreviation for dynamic contrast
control. In a high contrast
environment, this function
compresses the high light signal by
adjusting the knee point
automatically, allowing you to take
clear pictures in a dynamic range.

Drop frame mode
SMPTE time code runs at 30 frames/
second, while the NTSC color
television system runs at about 29.97
frames/second. Drop frame mode
adjusts the running of time code to
eliminate the discrepancy between
time code value and actual time by
dropping two frames from the time
code value at the beginning of each
minute except every tenth minute.

Drum
A metal cylinder to which the video
heads are attached. During recording
and playback, the drum rotates at
high speed in synchronization with a
control signal.

EBU
Abbreviation for European
Broadcasting Union. A professional
broadcasting establishment in
Europe.

EXT TC (External time code)
A time code input from external
equipment together with audio data.
It corresponds to the conventional
time code recorded on tape based
media. Instead the EXT TC is usually
used to record time codes and audio
signals that are played back by
equipment that is not synchronized
with the reference video signal.

Flange focal length
The length between the objective lens
and the surface of the imager.

and the surface of the imager.
Flare
The loss of contrast in an image
caused by unnecessary light that
strays into the image plane.
The loss of contrast in an image
caused by unnecessary light that
strays into the image plane.
Flicker
Repeated changes in screen
brightness caused by an interference
between the camera's scanning and
the lighting conditions.

GENLOCK
A state in which devices are locked to
a signal output by a sync generator.
Genlock allows multiple devices to
operate in synchronization.
A state in which devices are locked to
a signal output by a sync generator.

diode. A CCD sensor structure
designed to suppress certain types of
noise inherent to CCDs.

number of vertical lines
distinguishable when shooting a test
chart.
