1. A digital camera system comprising:
- a lens assembly mounted for receiving an image and projecting said image on an image plane;
a micro-electromechanical (MEMS) system support mechanism for providing at least two positions of movement to a supported element, said MEMS support mechanism being fabricated integrally with said supported element; and
a semi-conductor image sensor mounted at said image plane for movement on said MEMS system support mechanism and being operatively associated with said lens assembly to generate a digital image.

Abstract
A digital camera for use in a communication device in which the image sensor is formed on a substrate and is mounted on a micro-electromechanical system for movement relative to the camera lens to provide an autofocus capability. In addition the lens may be mounted on a micro-electromechanical system for movement relative to the image sensor to provide both an autofocus and a zoom capability.
