This is one of the reasons why I can't take most of the cameras on the cellphones seriously yet. Especially the commonly used CMOS-based ones. The image sensor scanning the landscape has takes certain time, even with sufficient lighting, as this photo I took on a day inside a car travelling around 70km/h shows. The cellphone used was CP-X501.
The image is actually quite crisp, so the shutter speed was quite fast, but the sensor scanning couldn't keep up with the fast-moving objects, resulting in a humourously warped shape for the box and the tree. Normal digital cameras, which use CCD, don't exhibit this problem. To this day I carry a separate digital camera on the belt to take quick photos and videos; my cellphone is mostly used for what it's supposed to do: make/get calls.
