Technology

The LDK 23HS mkII is a lightweight EFP/Studio high speed camera system which uses 2/3" frame transfer sensors with Dynamic Pixel Management (DPM).

Super Slow Motion

Unique live slow motion capability. The LDK 23 HS mkII scans at three time the normal rate. Instead of scanning at 50 Hz for PAL and 60 Hz for NTSC the LDK 23HS mkII scans at 150 Hz for PAL and 180 Hz for NTSC.

Various preset settings for artificial light conditions ensure a slow motion picture without pulsing light effects.

Sensor technique

Frame Transfer Dynamic Pixel Management allows the format of the sensors to be switched between 4:3 and 16:9 aspect ratio at the touch of a switch without loss of horizontal resolution. The 1000 pixels per line in both formats ensures that there is no loss in horizontal viewing angle.

Another aspect of the 2/3" DPM sensors is that there is no loss of vertical resolution between formats. They have a highlight compression/dynamic range of 400% and a high linear sensitivity over all camera lens apertures. The frame transfer technology ensures that there is no lag nor smear.

The Intelligent Continuous Automatics facility provides automatic control of black levels and black shading. Each DPM sensor has two lines of sensor elements that are protected from incoming light and therefore give a true indication of black. The black reference signal that they provide is used in the camera preprocessor circuits to monitor temperature changes which, if not corrected, would alter the black level. In this way continuous automatic correction is applied without operator intervention.

Film-like characteristics

To achieve film-like quality it is necessary to emulate the softly limiting S-shaped transfer characteristics of film. This is done by compressing the TV camera's near linear characteristics above a certain point, the knee. The pivoting knee circuit of the LDK 23HS mkII camera system adapts both the knee point and the compression ratio according to the highlight content of the picture. Significant highlights lower the knee point to give more room for compression, while minor highlights only affect the upper part of the transfer characteristic. Signals below the knee point remain unaffected. As a result, compression is only applied where necessary and in proportion to the highlight, and the pictures obtained have true film-like quality.

Advanced Triax Features

The Triax system allows remote control of camera up to a distance of 800 meters (1000 meter with minor performance degration). The Triax system uses YUV transmission.

The communication facilities provide for two-wire or four-wire high quality intercom signals.

The LDK 23 HS mkII is compatible with the existing Thomson Multimedia Broadcast Solutions Series 9000 UniversalCameraControlsystem.Basestationoutputs include triple and normal scan serial digital video signals.

SuperXPander

The optional LDK 4482 SuperXpander enables the camera to be used with large lenses so extending the camera's use in studio and EFP situations.
