Abstract
A compact zoomable camera device (10) for a portable digital electronic device is provided. The compact zoomable camera device includes: an optical system (100) for capturing images, an image sensor device (200) having an image sensor (220) positioned at a focal plane of the lens system for receiving the images and converting the images into electronic signals, and a microelectronic mechanism system (MEMS) micro-actuator (300). The optical system includes a lens system (110) for zooming and auto-focusing, wherein the focal plane of the lens system shifts according to the zooming or auto-focusing operation. The micro-actuator is adapted for driving the image sensor to move within a predetermined range to dynamically position the image sensor at the required focal plane of the camera device.
