Wavefront Coding for Mobile Phone Imaging

Facebook X LinkedIn Email
Joint optimization of nontraditional, specialized optics and sophisticated signal processing improves the image formation process.

Edward R. Dowski Jr., CDM-Optics/OmniVision Technologies Inc.

Conventional imaging systems use signal processing essentially as an accessory to optics, but Wavefront Coding allows specialized optics and signal processing to be jointly optimized to form the best image. This relationship enables increased imaging quality, reduced size and overall cost reduction that follows Moore's law. Wavefront Coding is not a new concept, but it is newly being used in mobile phone cameras where requirements for close focusing low-height optics and low-tolerance assembly are combined with the need for high target yields. In these systems, the technology enables...Read full article

    image
    In optics, an image is the reconstruction of light rays from a source or object when light from that source or object is passed through a system of optics and onto an image forming plane. Light rays passing through an optical system tend to either converge (real image) or diverge (virtual image) to a plane (also called the image plane) in which a visual reproduction of the object is formed. This reconstructed pictorial representation of the object is called an image.
