Quick and easy measurements. The SpectraViewII system,
available for Mac OS and Windows, uses an ultra-sensitive,
custom-calibrated NEC/X-rite iOne Display 2 colorimeter 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
SpectraViewII, 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.
10-bit Internal Look Up Tables (LUTs) - Each LCD monitor
supported by SpectraViewII features three internal 10-bit LUTs.
These tables allow precise adjustments to be made to the
display’s tone response curve with minimal reduction to the
number of displayable colors. Since the tone response curve
correction is stored within the display and not on the host
system’s video graphics card LUT, the display can be calibrated
on one machine and then used on another and still maintain
calibration as long as a digital video signal is used.
Display Data Channel Command Interface (DDC/CI) -
SpectraViewII communicates with the monitor using DDC/CI,
which is a two-way communications link between the video
graphics adapter and display monitor using the standard video
signal cable. No extra cables are necessary. All adjustments
to the monitor settings are done automatically using this
communications link.
Multiple calibration sets - Different 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.
Calibrated display information - At the end of each 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.
Application flexibility - SpectraViewII provides many features
and options that make it exible 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
specic user-dened value or set to the maximum the display
can achieve. In addition, custom target response curves can be
created in addition to presets such as L* and SMPTE.
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 an existing network
(LAN). This feature is particularly useful for large installations
where central monitoring and asset management is needed.
Monitor locking - Once calibrated, the On Screen Display (OSD®)
controls for the display monitors can be locked to prevent
accidental or unauthorized adjustment, which may invalidate the
calibrated state of the monitor.
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 proles use the Bradford
Chromaticity Adaptation matrix.
Colorimeter function - The software features a colorimeter func-
tion, which allows direct measurements to be taken by the color
sensor and the results displayed in a variety of different formats.
