Designed for professionals with color-critical applications, SpectraViewII combines
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 SpectraViewII system 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.

|
|
|
SpectraViewII is available on Apple Mac OS, Microsoft Windows, and some Linux distributions.

Top Features
|
|
|
|
High bit depth internal Look Up Tables (LUTs)
|
|
|
|
Each LCD display monitor supported by SpectraViewII features 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.
|
|
|
|
|
|
|
Fully automated calibration
|
|
|
|
By making adjustments directly in the display hardware, optimal settings are configured
without any user interaction. SpectraViewII communicates 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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
Calibration status validation
|
|
|
|
SpectraViewII will 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
|
|
|
SpectraViewII provides 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.
|
|
|
|
|
|
|
|
|
Network support (Windows only)
|
|
|
|
SpectraViewII integrates with the NEC NaViSet Administrator network software (available
separately from your NEC representative.) to provide remote network access and monitoring
of display monitors. NaViSet Administrator is able to read, display, and log the
current calibration settings and status of displays on a LAN. This feature is particularly
useful for large installations where central monitoring and asset management is
needed.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
DICOM GSDF calibration and conformance test
|
|
|
For use in medical imaging environments SpectraViewII can 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.
