GRASS VALLEY LDX 86 HS - 1.2 Camera Technology and Features

16 LDX 86 HS/XS HiSpeed/XtremeSpeed HD camera User’s Guide (v1.0)
Chapter 1 - Introduction
1.2 Technology
1.2.1 High speed acquisition
The LDX HiSpeed is the newest generation camera for 3X speed applications with improved
performance. It is also the first 3X speed camera system to offer an upgrade path to an ultra
slow-motion camera system via GV eLicenses.
The LDX XtremeSpeed 6X camera system sets a new standard for ultra slow-motion image
acquisition by introducing a workflow with instant time-to-air without a cumbersome double-
action memory buffer in the camera—so that not a single moment of the action will be missed
or lost.
Both cameras versions offer the highest sensitivity and image performance across all
acquisition speeds while the unique AnyLightXtreme flicker reduction assures that no more
irritating light flickering occurs in the replays.
Grass Valley LDX HiSpeed and LDX XtremeSpeed cameras are fully integrated with all the
LDX Series of cameras, so they share the same camera accessories and use the same camera
control system, which also includes the full support of the Connect Gateway for the best
possible integration with external control systems.
Fully integrates with Grass Valley K2 Dyno Replay Systems and includes K2 Dyno AnySpeed
technology which provides for smooth playback at any speed from 0% to 200%, dramatically
expanding the ability to tell a compelling story during replays.
1.2.2 Xensium-FT imagers
The LDX 86 HS/XS 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 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.
1.2.3 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 HS/XS 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.
