Lens Drivers Focus on Performance in High-Resolution Camera Modules
An Evolution of Resolution is driving the development of cell phone camera modules. Autofocus is now standard in high-resolution cameras, and features such as optical zoom, shutter control, and image stabilization are becoming common. These require the lens to move rapidly. The lens driver powers a motor to move the lens in response to digital signals. This article discusses three types of motors and how to drive them.

Hi author. Recently i'd choose this lens drivers topic as my assignment titled accelerometer application. Fortunately, this article has provided me very useful information, its system block diagram, concept of operation and specifications. My question is, how does the system interact with users? Has it got to do with growing demands for better handphone featured camera in the market? Or something else which i cant think of? It'll be good if there are more articles on this topic. Looking forward for your reply. Thank you very much.
What about digital autofocus solutions which eliminates the mechanical elements?
