Benefits of technology

[0011] In satisfaction of these needs and others, embodiments of the present invention provide continuous-zoom systems and methods which employ multiple optical pathways and digital zooming techniques. In addition, embodiments of the prov

Problems solved by technology

Due to these abrupt magnification changes, the field of view often crops out interesting objects, requiring time-consuming adjustments to the object's position.
Furthermore, microscopes containing optical zoom systems suffer from errors in alignment as the lenses are translated.
The moving mechanical components in the systems wear over time and motors produce unintended vibrations in the images.

Abstract

Improved methods and systems for imaging are provided. Specifically, systems and methods for extending the range of a digital zoom are provided in which an imaging system provides continuous magnification over a plurality of interleaved optical pathways and digital zooming imagers. Systems and methods of centering an image as the field of view changes, and for masking out undesirable obstacles from a magnified image are also provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 624,326 filed Nov. 2, 2004 the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to optically enhanced digital imaging systems, and specifically to improved systems and methods for multi-path optical magnification of a digitally zoomable image. BACKGROUND OF THE INVENTION [0003] Many scientific and engineering applications require individuals to be able to see and manipulate items which are not visible with the naked eye. Semiconductor manufacturers, for example, must be able to examine and probe micro and nano-scale circuits fabricated on various substrates. Similarly, biological researchers must be able to see and manipulate cells, proteins, micro-organisms and other microscopic elements within their laboratories. Microscopic and metrologic applications are as prevalent and diverse a...
