GLOSSARY
Automatic Gain Control (AGC)
Amplifies existing video to help camera reproduce a video signal at
very low light levels.
Analogue backlight compensation (BLC)
Picture brightness is adjusted automatically depending on lighting
conditions. Overcomes the problem of strong backlight which often
causes the subject of the picture to be cast into shadow.
Adaptive Picture Control (APC)
Automatically detects the condition of the recording head and video
cassette tape and then sets the optimum recording head current.
Available on all SVT time lapse VCRs.
Aperture/sharp mode
Makes object outline in the picture appear sharper. Ideal for
situations where an object merges into the scene with a similar
shade of colour.
Auto Tracing White Balance (ATW)
Adjusts the white balance automatically in response to varying light
conditions.
ATW PRO
Ideal for frequently changing light conditions and applications where
the operator needs to see objects as they appear to the eye.
Effective operational colour range is 2500 to 6000K.
Auto iris
Automatically adjusts the iris element as the light level changes.
Auto White Balance (AWB)
Automatically memorises adjusted white balance values.
Backlight compensation
See Smart Control (Digital)
See Analogue backlight compensation (Analogue)
C mount
Type of camera mount which measures 17.5 mm from the lens rear
mounting surface to the camera’s CCD.
CS mount
Type of camera mount which measures 12.5 mm from the lens rear
mounting surface to the camera’s CCD. CS mount lenses can be
used with C mount cameras by adding a 5 mm spacer.
DC servo auto iris lens
Lens that relies on DC power from the camera to control the iris.
Digital Signal Processing (DSP)
Converts the analogue signal from a CCD image sensor into a digital
signal through an internal A/D converter. The signal is then broken
down into luminance and chrominance components for processing,
adjustment and feature enhancement enabling many digital features
such as backlight compensation.
Duplex
Type of multiplexer allowing simultaneous live monitoring or
playback as images are being recorded.
Exwave HAD Technology
Sony's technology with a nearly gap-less OCL (On-chip-lens) located
over each pixel on the CCD resulting in more than twice the
sensitivity and 1/50 the smear compared to the Hyper HAD
technology. Used in SSC-DC50A/DC54A/DC393/M383 cameras.
Hybrid recording
Original Sony recording method of the HSR-2, which uses both a
Hard Disk Drive and DV tape. Images are first recorded to HDD,
then transferred to DV tape.
Hyper HAD Technology
Technology with an OCL (On-chip-lens) located over each pixel on
the CCD which helps increase sensitivity and reduce smear.
Real Action recording
EP recording mode which achieves four times as many frames/s to be
recorded in 24 H mode. (SVT-RA168/RA40 only)
Sensitivity
The amount of light falling on a scene measured in lx.
Simplex
Type of multiplexer which allows the user to choose between live
monitoring, recording or playback.
Smart Control
Digital circuit within the camera providing automatic backlight
compensation by automatically adjusting iris and gain. Also see DSP.
Smear
Vertical streaks above and below a brightly lit object or light source
when observed on the monitor. Vertical lines on the screen are
caused by the leakage of unwanted light onto the vertical shift
register of the CCD.
Super HAD Technology
Improves drastically the sensitivity compared to the Hyper HAD
technology by optimizing the shape of on-chip microlenses on the
CCD in order to minimize the invalid area between microlenses of
each pixel.
Synchronisation
Used in multi-camera installations where automatic switching is
employed and allows roll-free switching from camera to camera.
Trinitron CRT
Sony CRT which allows for high resolution and the best possible
picture reproduction. The completely flat, straight vertical surface of
the Trinitron CRT provides very low purity imperfection.
Triple multiplexing
Video, sync and power transmitted over a single coaxial cable.
Turbo AGC
Powerful automatic gain control function. Increases range of video
gain compared to conventional AGC resulting in greater sensitivity.
Video servo auto iris lens
Lens that relies on video input to control the iris opening. When the
video level is high, the lens iris closes. When the video level is low, it
opens.
