Introduction
1.1
Technology
The LDK 8000 is a high definition multi-standard, multi-format digital camera head using
three 2/3-inch HD-DPM
+
™ sensors. The camera head can be combined with the TriaxHD
adapter for a flexible camera that is equally at home in the studio or out on location.
1.1.1
HD sensors
The camera head uses HD-DPM
+
™ CCD sensors which offer superior performance and
ultimate flexibility. Native wide screen pictures in 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 million pixel 2/3" CCD sensors. These allow vertically
grouping of different numbers 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 sensitivity across all camera lens
apertures. They are based on Frame Transfer technology, which ensures that there is neither
lag nor smear.
1.1.2
Digital processing
The advanced digital processing of the camera is based on 14-bit A/D converters and more
than 22-bit internal processing. All major camera functions are processed in the digital
domain, including knee, gamma, contour, 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.
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 standardised 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.
