LDX 86 High Frame Rate/HD/3G/4K Camera Platform User’s Guide (v2.0) 17
Chapter 1 - Introduction
1.2.4 LDX 86 Universe
With the LDX 86 Series cameras, you no longer need to choose between a higher frame rate
like 6X, or higher resolution for 4K — you can have both in a single camera: the LDX 86
Universe. You can even upgrade to LDX 86 Universe features from other LDX 86 Series
cameras when you need to.
This advanced multiformat (HD/3G/4K) and multispeed (1X/3X/6X) content acquisition system
is combined with outstanding image performance, excellent light sensitivity and the ability to
use standard HD lenses. This allows broadcasters and content creators to use the same
workflows they use for HD, while delivering the best HD/3G high-speed slow-motion or 4K
viewing experience possible
1.2.5 Xensium-FT imagers
The LDX 86 Series camera heads uses custom-designed 2/3-inch CMOS Xensium-FT imagers
that offer superior performance and ultimate flexibility. Native high-definition video formats
(available video modes are depending on the camera model and 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.
1.2.6 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 86 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.
The Dynamic Detail Equalizer provides more control over image sharpness than ever before.
Detail enhancement can be fine-adjusted for each individual tonal range.
Video contrast adjustment offers unmatched 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.
LDX 86 Series cameras provides enhanced colorimetry, color matching, and picture
performance. Color temperature and tint are just two of the parameters that can be
simultaneously adjusted across multiple cameras.
1.2.7 Designed for the operator
The LDX 86 Series cameras 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.
