Rumored resolutions of camera images leak, along with price
Nokia Oyj.'s (
) fresh flagship phone, the Lumia 1020 is set to be unveiled Thursday, but
are already trickling out, following the phone's
via Microsoft Corp. (
Here's a run-down on what we know about the phone's camera, which is expected to be the
best smartphone camera available
-- rivaling all but the best point and shoots (other than lacking an optical zoom).
1/1.2" image sensor
Dual flash: LED + Xenon
OIS (optical image stabilization) via floating lens*
38 megapixel (4:3); 32 MP (16:9); and 5 MP (16:9) (with 7 pixels per "superpixel")
F2.2 aperture (some sources say this may be adjustable)
Manual internal shutter
2 GB DRAM
32 GB NAND Flash Storage
Camera grip with built in battery ($70 USD) (capacity unknown)
Wireless charging via backplate*
*This first popped up in
the Lumia 920
, and is also found in

The onboard "Amber" skin, which is Nokia exclusive will provide:
FM radio support
Flip to silence
Pro Camera app (control ISO, white balance, shutter speed, flash, manual focus)
The Pro Camera app is expected to stand in for the more blasé standard Windows Phone Camera app, although automatic settings will be available by default.
The phone will reportedly go on sale at
on July 22, unlocked, at a price of $602 USD. The Microsoft stores reportedly will carry three varieties -- yellow, white, and black. AT&T, Inc. (
) is expected to be the initial carrier for the (locked) version of the device, which is expected to feature additional colors (
International release prices and dates are unknown, at this point.

RE: I see to recall

First, I wasn't referring specifically to the iPhone. If I recall correctly those old discussions actually started with another brand of phone, but maybe it was the iPhone.
Second, you've actually supported my point. The real pixel support of this optics is likely for a true 16 Mp (at best) not 38 Mp camera.
The purpose of a Bayer array with one blue, one red and two greens per four pixel set is that the software for the focal plane array can interpolate for the green and red over the blue pixel, similarly for the green and blue over the red pixel and finally for for the blue and green over the red pixel. This way you can get a synthetic red, green, and blue for every single pixel in the array. In order to do that the airy disk must be approximately the size of an individual pixel or smaller. Disks, as you describe, that cover all four pixels, or are larger than that, do not give independent information on each individual pixel.
I'm sure the images that are exported from this camera are the full "38 Mp" implying to the user that they have 38 Mp of independent pieces of pixel information and not the approximately 16 Mp you mention. It is *possible* to do lots of interpolations -- especially if HDR is implemented -- as I mentioned before (especially if you can play the math against the color versus quantum efficiency curves of the focal plane array), but the amount of independent information across each individual pixel is minimal at best.
In theory you can push a 1k x 1k array to about 30k x 30k, but this requires nearly a perfect set of interrelated information:
just the right amount and angular rate of motion and jitter
the optimum cross correlation between the quantum efficiencies as various color bands
the maximum number of independent frames of information observing static or nearly static targets
and so on and so on.
I doubt very much any of this is what Noka is claiming with the phone camera.
Also these calculations assume several not realistic implementations (not realistic in low cost optics):
nearly infinitely thin lenses,
fully achromatic optics,
zero coma on the FPA,
Each of these further degrades the imagery.
Finally, I wasn't talking about physical limits being broken. There are lots of fun things that can be done with multiple rapid frames, FPA jitter, inter frame interpolation (e.g., in HDR mode), multi frame super resolution effects and such. However, implementing those in a phone seems extremely unlikely. If there is a physical limit to discuss it is about the airy disk of a given optics being on the order of -- or smaller than -- a single, physical pixel. When that limit is crossed, either the number of pixels is excessive or a LOT of fancy footwork in the software must be done to recover each modicum of different information obtained.
Thus I'm still at a loss as to why a 38 Mp camera is included unless it is just for bragging rights.
