reread it and am confused about the section below? How did they
obtain the 10 degree FoV measurements? Is it in the device? I guess
they don't really reveal their "process".
I think the concept here is "calculated based on a 10 degree field of
view". Its not a measurement factor, its a calculation factor. Instead
of using a CIE Observer based on a 2 degree field of view (reading
vision) they use the one based on 10 degree (broader field of vision).
ICC is based on 2 degree; big, flat colored objects (textiles, car
paint) use 10 degree. Its just a different standard for replicating a
different component of human vision. Since a flat gray 22 inch screen
is a large object, they are looking at using that matching function.
It has nothing to do with the devices they are measuring with.
