1-2 Operator's Manual - LDK 6000 mkII Introduction
The LDK 6000 mkII is a high definition multi-standard, multi-
formatdigitalcameraheadusing2/3-inchHD-DPM+™sensors.
The camera head can be combined with the TriaxHD adapter.
This flexible camera is equally at home in the studio or out on
location.
HD Sensors
The camera head uses HD-DPM+™ CCD sensors which offer
superiorperformance and ultimateflexibility.Native wide screen
picturesin the high-definition formats 1080i,1080p(WorldCam)
and 720p are produced at the touch of a button. This unique
native multi-format capability is realized with innovative 9.2
millionpixel 2/3" CCD sensors. These allow vertically grouping
ofdifferentnumbers of pixels on the sensors themselves. There
is no need for HDTV format conversion during digital signal
processing which would lead to quality degradation.
These sensors have a high dynamic range and high linear
sensitivityacrossallcameralensapertures. They are based on
FrameTransfertechnology,whichensures that there is neither
lag nor smear.
Digital Processing
Theadvanced digital processing of the camerais based on 12-
bit A/D conversion and 22-bit internal processing. Two DSPs
combineallmajorcamerafunctionsinthedigitaldomain,including
knee, gamma, contour, matrix and colour correction.

black reference signals that are used to monitor temperature
changes. This means that continuous automatic correction is
appliedwithoutoperatorintervention.
The digital contour processing uses full amplitude video RGB
signals via an extended dynamic range contour circuit.
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
gammasequenceissoftwareprogrammable 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
characteristicsoffilm.DigitalTrue ColourKneecircuitrymaintains

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
improvingthe contrast impression by simulating theS-curve of
film.
Focus assist
WithHDTV,focusingis even more critical than before. The LDK

SuperXPander
TheSuperXPander large lensadaptertogetherwith the optional
7-inch HD high resolution viewfinder turns the portable triax
camera into a full-featured studio camera for studio and EFP
situations.
Different versions
The LDK 6000 mkII camera head is available in two versions -
StandardandWorldcam.
The Standard version supports 1080i/720p HD formats in 50,
and59.94 Hz, and simultaneously provides high-quality SDTV
outputs in either 50 Hz or 59.94 Hz.
The Worldcam version provides, in addition to the Standard
version, digital cinematography formats in 1080p and 720p,
whichgiveanimpression of motion comparable to film cameras
running at identical speeds.
The Worldcam also provides convenient built-in frame-rate
conversions for easy connection to existing HD peripherals,
offeringpossibilitiesforcost-effectivemonitoring and recording
combined with the motion portrayal of film cameras.
Thismeans that the 1080p23.98 format canbeconvertedby the
3:2pull-downmethodto1080i59.94withinthecamera.Thesame
principle is offered through frame repeats for the 720p formats
at the lower frame rates. For example, the 720p23.98 format is
available as a 720p59.94 format. For p24 production, the
Worldcam enables 2.5 times slow-motion. In the 720p59.94
format, gathered video material provides a relative 2.5 times
slow-motion when the 59.94 Hz recording is played back at
24 Hz.
