关于4s camera的扯胡该停止了 http://www.pcmag.com/article2/0,2817,2394863,00.asp#fbid=XMGj3k In terms of sharpness, the 4S captured 1,186 lines per picture height—much better than the 711 lines recorded by the iPhone 4 or the 899 lines captured by the HTC Amaze. Our Editors' Choice for budget cameras, the $130 Panasonic Lumix DMC-S3 records 1,615 lines, which is much closer to the 1, 800 lines required for an acceptably sharp image. Image noise was at 1.1 percent at ISO 100, which was the setting that the phone defaulted to under our studio lights. Under the same conditions, the iPhone 4 recorded 1.3 percent noise, approaching the 1.5 percent that denotes an image that is overly grainy. I moved the color test chart to various areas in the lab trying to get the phone to shoot at a higher ISO. I was able to push it to ISO 640, where noise crossed the 4 percent mark— which would be considered downright awful in a point-and-shoot. The Lumix S3 records 1.2 percent noise at ISO 800 and hits the 1.5 percent mark at ISO 1600.
