Image warping and enhanced edge-blending 4
Direct key access to the most-used major
functions and auto set-up of sources with
correct brightness, contrast and position means
operation and set-up of the Christie Mirage
Series are intuitive.
When Christie first announced their Mirage S+4K
projector, VR specialists Virtalis became an early
adopter, recommending it to the British Geological
Survey. A Christie Mirage S+4K is rear projected
with a 0.73:1 lens on a 3.1m x 2.3m screen as part
of an integrated StereoWorks 3D visualization
system at the British Geological Survey’s
headquarters in Keyworth, Nottingham, UK.
Christie TwistTM – total image control
Christie TwistTM is a dedicated, purpose-built
hardware and software solution that enables
full image warping and advanced edge-
blending through the control of a powerful
and easy-to-use Graphic User Interface.
Users can expertly control seamless, multiple
edge-blended, curved images. Images can
be warped to fit virtually any projection surface
– flat, curved or spherical screens – with perfect
pixel-to-pixel alignment.
The internal hardware module is integrated
into the 10-bit image processing module.
Latency is typically as low as 10-20 lines.
Once the warping and blending grids are set
for multiple projectors, the properties will be
stored on the projectors and on the external
PC. Multiple blend and warp properties can
be stored on the projectors – providing easy
access and immediate recall of settings.
As an additional optional software upgrade,
Christie TwistTM Pro is a single license that
supports an unlimited number of projectors
per array and an unlimited and arbitrary
number of grid lines, up to and beyond
a 10'x 10'grid. Christie TwistTM Pro features
advanced edge-blending, with rotate and flip
capabilities, a gradient preview of edge-blends
and a brightness uniformity controller.
Brightness uniformity control
Adjusts center-to-edge brightness uniformity
across the image – with the Christie Mirage
Series you can achieve up to 90% uniformity.
Dark Interval Adjustment (DIATM)
DIATM gives the user a mechanism to tune the
projector’s interaction with the LCD shutter
glasses to achieve the optimum image with a
minimum of color artifacts or cross-talk between
left and right eye images. The dark interval is
the time between left and right frames when
the projector is showing black.
Stereo sync harness
Simplifying projector set-up for the end-user,
the stereo sync harness can provide projector
control of the phase of the output through
the menu. This purpose-built function for active
stereo projection supports emitters and enables
left/right inversion.
