Sony CEO Lets Slip That iPhone 5 Will Have 8MP Camera 176
An anonymous reader writes "During a recent interview with Walt Mossberg, Sony CEO Sir Howard Stringer may have inadvertently let it slip that Sony plans to supply Apple with 8 megapixel cameras for the next-gen iPhone. While discussing the Japanese earthquake, Stringer noted that Sony's camera sensor plant in Sendai had been affected and that shipments of 8 megapixel camera sensors to Apple were subsequently delayed."

You do realize, that other than raw numbers, megapixels have very little to do with final quality?

You do realize that cellphone sensors are limited by diffraction so while you can resolve finer detail through unsharp masks, physics does limit the usable resolution of optical sensors. Making things worse, the need for anti-aliasing filters will further soften the photos. APS-C DSLRs have reached the point where they are diffraction limited to f/8.0 and yet while the megapixel race has slowed down a bit, it has not yet ended. If you need a 100% crop from the newest APS-C cameras, it requires minor to moderat sharpening during postprocessing. As the sensor size decreases the circle of confusion becomes relatively larger as the photo sites ("pixels") decrease.
Unless they find some way to increase the lens size (which will require bending space-time) the megapixel race is utterly pointless, because the resulting photos will either appear softer and softer, or more and more artificial due to requiring more and more sharpening.

There have been a lot of technology advancements that dramatically increase the amount of light each photosite can collect. The biggest is BSI (back side illuminated) sensors which can double the amount of light that gets captured per photosite. We are also moving to high-dynamic range, high-speed, and pixel-binning CMOS technology that can combine signal data from multiple photosites into one.

In general you will get better quality from a larger sensor, all things being equal, but technology has moved considerably forward. 1~2 micron photosites (that are common in cellphones) can easily handle 8MPs. But don't expect it to take the same quality as a dSLR (or even the larger sensored point and shoots).
