1.1.3 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.
1.1.4 Focus assist
With HDTV, focusing is even more critical than before. The LDK 8000 has special patented
focusing aids. A unique viewfinder zoom function enlarges the viewfinder image instantly
with a simple press-button action, thus providing improved means for focusing. A patented
crawler circuitry adds motion in the viewfinder to objects in sharp focus.
1.1.5 Different versions
The LDK 8000 camera head is available in two versions - Standard and Worldcam.
The Standard version supports 1080i/720p HD formats in 50, and 59.94 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 formats, digital
cinematography formats in 1080p and 720p, which give an impression 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, offering possibilities for cost-effective monitoring and recording
combined with the motion portrayal of film cameras. The 1080p format at 23.98 Hz, for
example, can be converted using 3:2 pull-down to 1080i at 59.94 Hz right inside the camera.
