Overview
Designed for professionals with color-critical applications, SpectraViewIIcombines
award-winning NEC display technology with a color-measurement sensor and
sophisticated calibration software. The result is highly accurate, reliable,
repeatable, feature-rich solution for display calibration and profiling.
The SpectraViewIIsystem
uses a color sensor to take color measurements of the display screen during
calibration. The software analyzes these measurements and sends color adjustment
commands directly to the display monitor. This means that color adjustments are
made in the monitor rather than in the video graphics adapter. With
SpectraViewII,
the video graphics adapter is not used at all to make any gamma or Tone Response
Curve corrections to the display, so the fidelity of the system is
maintained.
Features
High bit depth internal Look Up Tables (LUTs)
Each LCD display monitor supported by SpectraViewIIfeatures
three internal 14, 12 or 10 bit LUTs (depending on model). These tables allow
very precise adjustments to be made to the display's Tone Response Curve without
reducing the number of displayable colors.
Monitor locking
Once calibrated the OSD (On Screen Display) controls for the display monitors
can be locked to prevent accidental or unauthorized adjustment which may
invalidate the calibrated state of the monitor.
Fully automated calibration
By making adjustments directly in the display hardware, optimal settings are
configured without any user interaction. SpectraViewIIcommunicates
with the display monitors using Display Data Channel - Command Interface
(DDC/CI) which is a two-way communications link between the video graphics
adapter and display monitor using the normal video signal cable. No extra cables
are necessary.
Colorimeter function
The software features a Colorimeter function which allows direct measurements
to be taken by the color sensor and the results displayed in a variety of
different formats.
Multiple Calibration Sets
Different display monitor calibrations can be instantly loaded allowing quick
and easy switching between different calibration settings without the need to
re-calibrate the display. Each time a calibration set is loaded, the necessary
monitor settings and ICC/ColorSync profiles are automatically updated.
Monitor Profiling
After calibration, the display is automatically profiled and highly accurate
ICC/ColorSync color profiles are generated and automatically registered with the
Color Management System. These profiles use the Bradford Chromaticity Adaptation
matrix.
Informative
At the end of each display monitor calibration, an information window is
displayed which shows the results of the calibration and includes a wealth of
information about the display such as the measured color gamut, grayscale color
tracking, Delta-E, and luminance values. Additional information about the
display monitor such as the model name, serial number and the total number of
hours that it has been in use are also displayed.
DICOM GSDF calibration and conformance test
For use in medical imaging environments SpectraViewIIcan
be used to calibrate the monitor to the DICOM GSDF gamma curve. The built in
conformance test can be used to verify accuracy of calibration and conformance
to the recommended standard for viewing grayscale images.
Calibration status validation
SpectraViewIIwill
query each calibrated monitor to see if any controls have changed since the last
calibration. If anything has changed, the previous calibrated state can be
restored automatically.
Flexible
SpectraViewIIprovides
many features and options that make it flexible enough to be used in a large
variety of applications, including full DICOM support for medical imaging. The
display luminance can be adjusted to either a specific value or to the maximum
possible that the display can achieve.
