2.7The Apple iPhone 3G S adds some significant under-the-hood improvements, including an updated three-megapixel image sensor with autofocus and video recording. The camera performed well in color accuracy and resolution, but we disliked the shortage of controls.
The iPhone 3G S records video at standard definition (640x480) at 30fps, using the h.264 codec. As with still photography, there's almost no control over the video mode. You can tap on an area to focus there, easily trim files down, and upload them to YouTube.

Video Color(8.47)
The iPhone 3G S's color was pretty good in video mode. It had a color error of 4.72, and oversaturated the color by 110%. This is quite accurate, as you can see in the chart below. The bars represent color error, so shorter is better. There are no scores for the other two iPhones, as neither can record video.

Video Sharpness(1.79)
In terms of video sharpness, we were able to see fine detail down to 500 line widths per picture height horizontally, and 375 vertically. For standard definition video, that isn't bad, though it struggles when compared to the Sony T900, which records in HD. There are no bars below for the other two iPhones, as neither can record video.
