The SpectraView II 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, resulting in full use of the number of colors
available on the graphics adapter and a much brighter
image with the maximum possible color gamut. With
SpectraView II, the video graphics adapter is
not used at all to make any gamma or Tone Response Curve
corrections to the display, so the full color resolution
and fidelity of the system is maintained.
SpectraView II is available on Apple Mac OS, Microsoft Windows, and
some Linux distributions.
Features and benefits:
High bit depth internal Look Up Tables (LUTs) - each LCD display monitor supported by SpectraView II
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. SpectraView II
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
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 -
SpectraView II 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 - SpectraView II
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
Network support (Windows only) -
SpectraView II 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 SpectraView II 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.
