Chapter 1 - Introduction
1.2 Technology
1.2.1 Xensium-FT imagers
An LDX Series camera head uses custom-designed 2/3-inch CMOS Xensium-FT imagers that
offer superior performance and ultimate flexibility. Native high-definition video formats 1080p,
1080i and 720p (available video modes are depending on the camera version) are produced at
the touch of a button.
Progressive frame sampling is the native imaging mode, providing complete frame samples.
The entire imager surface is used for image sampling—there are no interline transfer channels
which introduce aliasing artifacts.
Xensium-FT imagers have a high dynamic range and high linear sensitivity across all lens
apertures. There is no shutter and no vertical smear effect.
1.2.2 Superior digital processing
The advanced video processing of the camera is done with floating point precision while all
major camera functions are processed in the digital domain, including knee, gamma, detail,
matrix and color correction.
To make images look their best, the LDX Series cameras incorporate TrueTexture™—a unique
feature to preserve texture throughout all processing parameters.
Chromatic lens aberration correction (CLASS) offers impressive sharpness improvements on
the outer regions of the image by canceling out shifts in color registration. This algorithm
works in conjunction with lens data, using industry standard lens interface protocols.
For Première, Elite and WorldCam versions, the Dynamic Detail Equalizer provides more
control over image sharpness than ever before. Detail enhancement can be fine-adjusted for
each individual tonal range.
For Elite and WorldCam versions, video contrast adjustment offers unmachted creative control
over the luminance levels of the picture: shadows, midtones and highlights can be adjusted
individually while natural transitions between the areas are maintained.
The LDX Series provides enhanced colorimetry, -matching, and picture performance. Color
temperature and tint are just two of the parameters that can be simultaneously adjusted
across multiple cameras.
1.2.3 Designed for the operator
The LDX Series offers even more operational excellence. Button layouts as well as control
knobs are ergonomically designed to allow the operator to find the right adjustments easily.
Full control flexibility is possible thanks to well dimensioned control knobs. With the easily
accessible separated info button, operational information can de displayed in the viewfinder
instantaneously.
The user-friendliness of LDX cameras has been further improved by using a streamlined
camera menu structure that allows operators to access commonly used functions more
quickly. The camera menu is arranged around operational, video setup, creative setup and
system configuration.
Another imaging innovation is ArtTouch™, an intuitive interface between the operator and hard
wired controls, which significantly enhances artistic possibilities during live broadcast.
ArtTouch includes smart coupling of video control functions.
