Need to read more than just Apple propaganda, Craig. Like,

Cool!
Now tell me where I can buy a TV that supports HDR and WCG that I can connect
the new Play Station to...
It's a good bet that Sony is working on one.
But this misses the point, as the article explains. Apple has been the pioneer
of many new technologies, with the rest of the industry eventually following.
My whole point about posting stuff like this has NOTHING to do with Apple.
For more than two decades I have promoted the FACT that higher pixel counts
alone do not help deliver better quality images. We had the opportunity when
the ATSC standard was created to deal with the major issues that limited image
quality at the time:
- The use of interlace
- The use of a color gamut optimized for CRT phosphors
- The use of a limited sample space (8 bit) and the continued use of gamma
curves that limit the dynamic range of the luminance component of the TV system
So here we are only 24 years later and the CE industry is FINALLY waking up.
Interlace is almost gone, except on a few stubborn TV networks that are holding
onto 1080i.
16 bit samples are now being processed on an iPhone that can acquire and
display HD video with HDR and WCG.
But far more important, the resolution of the content is not the issue.
Progressive scan, HDR and WCG improve delivered image quality at ANY
resolution, even the 360P and 480P that you watch while streaming through your
PC with your crippled DSL "broadband."
Let's hope the industry once again follows in Apple's footsteps...
Plus, I wouldn't bet on HDR. We already went through the HDR-on-smartphones
hype and BS recently. Compressing dynamic range is the opposite of HDR. HDR
means a large difference in actual transmitted brightness, between black and
the brightest white. What they have to do in smartphones is the opposite of
HDR, and they fool people by using the wrong technical term.
That was a technique developed for still photography about 3 generation of
iPhone ago. Clearly these improvements are incremental. I honestly do not know
what the dynamic range of the new iPhones is. Apple is not promoting HDR as a
feature...yet.
My guess is that it will be included next year in the 10th anniversary iPhone.
As you are well aware, the standards are still being written...
Plus, as the other article you posted states, the dual cameras are not news,
nor are stabilized lenses. We have seen them in TV ads for quite some time.
Apple adopts technologies like a lot of other companies do, Craig. This is,
you know, how should I put it, "a well-known fact."
Sometimes Apple pioneers new technologies. Sometimes they wait until the
technology is mature enough to be viable, and then introduce products that
define the product category.
With respect to the dual cameras and image stabilization, Apple is just as
dependent on suppliers as any other manufacturer, although they often help fund
the development of new components, and get a brief advantage from those
investments.
Where Apple is breaking new ground is in the digital image processing area,
where they have the ability to create powerful image processing cores on the
chips that are at the heart of iOS devices. Dual cameras are not a new idea.
But processing the samples from these cameras to creat depth of field effects
that have only been possible on cameras with large lenses is a breakthrough.
And adding support for Wide Color Gamut from acquisition to display is a first,
which was worthy of our attention.

Craig
