Hi all,
I have performed multiple tests on portable device and this is my
impression :
The Ipad and other Apple devices try to match the sRGB standard.
Google Nexus series try to match the sRGB standard.
Samsung devices are the largest color space of portable device, the color
space is bigger than EciRgbV2 color space.
See the color gamut of iPad 3 Samsung note 2 and sRGB, EciRvbV2 here :

ring
For the measurement :
• Eizo color navigator (need Eizo monitor).
• dispcalGUI (opensource, free).
• And others….
Warning, If you use Aquafadas or Adobe DPS, all the pictures are
automatically converted to sRGB at export.
If ou develop your own application (objectiveC or JAVA code), it depends
on the device.
My opinion :
The EciRgvV2 color space is not good for working with portable device.
Maybe this can help you.
Best regards

Objet : Re: [ECI-EN] Creating a new/own Working Space, which includes the
colorspaces of mobile devices
Hello Martin,
just some additional information:
I just did some Gamut visualization in Chromic Color Think Pro and
compared eciRGB_V2 to an iPhone Display profile I found (from a
trustworthy source).
To make things short:
The gamut of mobile devices is well inside the eciRGB_V2 color space.
So I would recommend to just use eciRGB_V2 as Working Color Space.
Best regards,
Dieter

Hello guys,
I’m a student at the BU Wuppertal in Germany. I’m working on a project for
Prof. Dr. Stefan Brües, with the main goal to create a new workingspace
which includes the colorspaces of mobile devices like apple iphones/ipads.
Therefore my question, how can
i create a new/own workingspace? Which tools i need and how can i do
this. My idea is it to do it like the „PRMG“, to find the highest common
<http://www.dict.cc/englisch-deutsch/common.html> factor
<http://www.dict.cc/englisch-deutsch/factor.html> of
the colorspaces of mobile devices and to create the workingspace on this
basis. Could someone help me with more informations? Further i would to
know, how could i create a linear relation between the primary colors in
my own workingspace to get a neutral grey,
when my primary colors have the same value? And how i create a
equidistant workingspace?
Additional i would to know, why is the gamma value and the whitepoint (D50
or D65) in working spaces fixed? What are the benefits?
And what are the benefits of a workingspace with a linear relation between
the primary colors and of equidistant between the colors?
I hope someone can help me with answering these questions.
I’m looking forward to hear from you guys.
Best regards,
Martin Kytzia
