Imaging Apparatus and Method Comprising Imager and Optics Actuator Means

摘要

An imaging device and method of providing an increased depth-of-field of an electronic image. The image sensor and the optical lens assembly are selectively repositionable along the optical axis of the lens using electronic actuator elements such as piezo-electric actuator elements, A plurality of images of a scene are captured while the image sensor, the optical lens assembly, or both are positioned at predetermined locations along the optical axis. Selected elements of each of the images captured using different focal planes are electronically combined to define a final image having an increased depth-of-field.
