White Paper 034 Addendum 59: Tests and Settings on a Thomson/GV LDK3000

Alan Roberts

Abstract

A short assessment was made on a sample of the LDK3000, a multi-standard HDTV camera, tested with a Canon HJ17ex7.6B HD lens.

Physically, it resembles many other system cameras, the familiar digibeta size and layout. It has 3 ⅔" CMOS sensors, good connectivity, and operates at 1080-, 720- and SDTV standards. Much of the content of this document is taken directly from the manual.

Power consumption is 40 watts and it weighs 5.3kg, both typical for a system camera. However, the power management and cooling system keep the camera cool to the touch, and acceptably quiet acoustically. The camera has both neutral and colour-temperature filter wheels. The camera is connected to its CCU via conventional Triax cable.

The LDK3000 operates at 1080i and 720p resolutions, at 50 and 59.94Hz. The menu structure and contents are both very similar to those of the LDK8000/4000, with only a few items missing (e.g. noise reduction), indicating that similar processing is used throughout.

Sensitivity is claimed to be F/9 for 2000 lux illumination at 90% reflectance, a little lower than is normal for system cameras. Noise level is claimed to be -56dB.
