Operator's Manual - LDK 5000
Introduction
The LDK 5000 is a digital camera head using 2/3-inch FT CCD
sensors. The camera is combined with the Triax adapter. This
flexible camera is equally at home in the studio or out on
location.
The sensors have a high dynamic range and high linear
sensitivity across all camera lens apertures. They are based
on Frame Transfer technology, which ensures that there is
neither lag nor smear.
Digital Processing
The advanced digital processing of the camera is based on
12-bit A/D conversion and 22-bit internal processing. Two
DSPs combine all major camera functions in the digital
domain, including knee, gamma, matrix and colour correction.
The intelligent continuous automatics facility provides
automatic control of black levels and black shading. Each
sensor provides black reference signals that are used to
monitor temperature changes. This means that continuous
automatic correction is applied without operator intervention.
Colorimetry is selected by means of a variable 6-point digital
matrix or via preset matrices. Digital gamma circuits provide
a wide range of standardized gamma curves and enable soft
contrast in black scenes to be enhanced, together with hard
contrast and saturated colour in bright scenes. The matrix
and gamma sequence is software programmable for precise
colour matching.
Film-like characteristics
The pivoting knee circuit adapts both the knee point and the
compression ratio according to the highlight content of the
picture to emulate the softly limiting S-shaped transfer
characteristics of film. Digital True Colour Knee circuitry
maintains the correct hue for compressed highlights,
reproducing colours faithfully, even overexposed skin tones.
Digital contrast circuitry provides a black stretch function for
more detail in black areas and a black press function for
improving the contrast impression by simulating the S-curve
of film.
SuperXPander
The SuperXPander large lens adapter together with the
optional 7-inch high resolution viewfinder turns the portable
triax camera into a full-featured studio camera for studio and
EFP situations.
Technology
Advanced Triax Features
Triax, which is a further development of the Emmy Award
winning triax transmission system, makes the camera
compatible with industry standard triax cables. This allows
the reuse of existing, reliable and valuable cable inventories.
Triax allows video transmission and remote control of cameras
up to a distance of 3300 ft (1000 meters) and beyond, using
industry standard 14mm triax cables. It is based on 30MHz
full-bandwidth 4:2:2 transmission (Y/Cr/Cb components).
The double side band modulation technique used in
combination with Y/Cr/Cb transmission ensures linearity,
resolution and an optimal signal-to-noise ratio over the
maximum cable length. Bandwidth efficient channel combining
and equalization techniques minimize cross-talk and
interference. Teleprompter and viewfinder signals maintain
high performance with relatively long cable lengths.
The communication facilities provide for two-wire or four-wire
high quality intercom signals. Full camera control is provided
via the existing Series 9000 Universal Camera Control system.
The Triax adapter is equipped with a rotary triax connector
which provides freedom of movement during portable use of
the camera and protects the connector from being damaged
in near-floor conditions.
Triax Base Station
The Triax Base Station, besides high definition outputs,
optionally offers simultaneous high-end SDTV outputs.
