White Point - NEC SpectraView II Guia Del Usuario

42 | NEC SPECTRAVIEW II - USER'S GUIDE
SpectraView includes several industry standard targets for a variety of applications:
Target Name
Print Standard Commonly referred to as Proofing
Standard. Used widely for the
proofing of color transparencies or
press output.
Photo Editing Used for editing and previewing
images in a controlled lighting
environment. An Intensity of 140
candelas (cd/m²) is used.
Broadcast Used for editing images and
video intended to be displayed on
Video
televisions using the NTSC, PAL,
or SECAM standards.
sRGB Digital images, printing and the
Internet
Emulation
DICOM GSDF Medical Imaging using blue-base
- Blue Base film.
DICOM GSDF Medical Imaging.
- Clear Base
Digital Cinema Images and video intended for
cinematic projection using DCI.
Note 1:
• Color Gamuts other than Native (Full) and sRGB are only available on the MultiSync PA series displays.
When used on other display models that do not support color gamut control the Color Gamut setting will be
ignored.
Note 2: When using the sRGB Emulation target
• This is a special target that will switch the display into the sRGB Emulation mode which reduces the color
gamut to approximate that of sRGB.
• The Factory Preset white point is used on the following models: LCD2690WUXi, LCD3090WQXi and P221W.
It is not possible to adjust the white point of the sRGB Emulation mode on these models. The calibration will only
adjust the Intensity and generate an ICC/ColorSync profile of the display on these models. The resulting Delta-E
values may be higher than normal because the white point is not adjusted using the calibration sensor.
• On the LCD2690WUXi, the range of Intensity values that the display can be calibrated to using the sRGB
Emulation target is limited. It may not be possible to achieve low Intensity values (below roughly 120-150 cd/m²).
• SpectraView Engine equipped monitors will adjust the white point as well as the Intensity. (Refer to the
"SpectraView Engine" column in the "Features by Model" tables on page 58 and page 60.)
Note 3: When using the Broadcast Video target with SpectraView Engine equipped monitors (refer to the "SpectraView
Engine" column in the "Features by Model" tables on page 58 and page 60):
• This target preset uses the SMPTE-C color gamut primaries typically used for NTSC video.
• For applications using HDTV, the color gamut can be modified to use the sRGB preset color gamut which is
the same as ITU-R BT.709.
• For applications using PAL or SECAM, the color gamut can be modified to use the EBU/ITU (PAL/SECAM)
preset color gamut.
