Aliasing
Sampling is performed in converting an
analog signal to a digital signal. Aliasing
is a type of interference distortion which
can be introduced in the sampling process.

Auto knee
A circuit which automatically adjusts the
knee point to allow the video camera to
image with a wider dynamic range (the
range of brightnesses the imaging device
can handle).

CC filter
See Color temperature conversion filter.
Color temperature
A value which tells whether the color of
light tends towards red or towards blue,
and expresses that as a temperature in units
of K (kelvin). The value is lower as the
light tends toward red, and higher as the
light tends toward blue.

Color temperature conversion filter
(CC filter)
(CC filter)
A filter which adjusts the color
temperature so that the same color tones as
would be seen with light of a standard
color temperature can be obtained with
whatever illumination source is being
used.

Glossary
Ff
An abbreviation for Flange Focal Length.
Flange focal length
The distance from the lens mount plane to
the image forming plane.
the image forming plane.
Flare
Light which enters the lens but is not
needed for forming an image reaching the
image forming plane, and by some means
harming the contrast of the image.

image forming plane, and by some means
harming the contrast of the image.
Flicker
A phenomenon resulting in a flickering
image due to variation in the brightness of
a light source in sync with the power line
frequency.

a light source in sync with the power line
frequency.
Genlock
An abbreviation of generator lock. Used
to synchronize video equipment using a
standard sync signal.
to synchronize video equipment using a
standard sync signal.
Hunting
Repeated operation of the auto iris,
resulting in the image getting alternately
darker and lighter. A type of malfunction.
resulting in the image getting alternately
darker and lighter. A type of malfunction.
ND filter
An abbreviation for Neutral Density filter.
The ND filter allows the amount of
incident light to be decreased equally
across the entire spectrum.

incident light to be decreased equally

Pedestal level
The standard black level of a video signal
when photographing. Since there is noise
in the black region of the video signal, the
master black level is set above the
blanking level.

Return video
A video signal sent from the camera to the
VTR is sent back to the camera, or when
multiple cameras are being used, a video
signal selected by the control board is sent
back to the cameras so the camera
operator(s) can monitor the image. This
video being returned to the camera is the
return video.

Two-line image enhancer
A circuit with the function of delaying the
video signal for 2H (two horizontal scan
line times) for use in obtaining a signal
used in vertical and horizontal edge
enhancement.

Vertical smear
Bright vertical bands can appear in the
image when photographing an extremely
bright subject with a CCD camera. This is
called vertical smear. This smear is
greatly reduced with an FIT-type CCD
camera.
