Camera phones have sounded the clarion call for innovation in image performance. Camera phones have sounded the clarion call for innovation in image performance. Camera phones have undeniably become the most convenient tool for shooting emergency scenes. But even the most casual photographers are reluctant to give up their standalone digital cameras (DSCs) and rely solely on camera phones to capture those important moments. In this case, image sensor companies and camera phone designers have to fight a long road before the cameras in mobile phones can truly compete with standalone digital cameras. Technical challenges for camera phones include enabling camera phones to capture better quality photos in low-light environments and adding high-performance features such as autofocus and optical zoom without sacrificing the phone\'s ultra-thin form factor , or without increasing the cost of the phone. Indeed, compared with standalone digital cameras, \"camera phones have 20 times less available space, and they need to cost 20 times less,\" said Jess Lee, vice president of mainstream products at image chip provider OmniVision Technologies. These harsh realities have led some vendors to question whether upgrading the camera capabilities of camera phones to high-end digital cameras is worth the effort. Research shows that \"90 percent of camera phone owners never print out the photos they take with their phone,\" said Philippe Quinio, director of marketing at STMicroelectronics\' (ST) Imaging Products Group.

Specifically, 7 billion of the photos taken by camera phones worldwide have never been uploaded or printed, said Rutie Adar, director of product marketing for TransChip, a developer of CMOS imaging products. Many consumers simply don\'t bother to learn how to extract photos from their phones. Even those who did extract the photos did not print them because they felt the image quality was too poor. Kodak draws a sharp line between a camera phone and a standalone digital camera, calling the former \"a device that takes pictures\" and the latter \"a device for taking pictures.\" If current trends continue, \"camera phones are going to become a niche product,\" said Nancy Carr, vice president of marketing for Kodak\'s Strategic Relations Division. \"You have to get it right or you\'ll lose business.\"…
