Wavefront Coding for Mobile Phone Imaging
Joint optimization of nontraditional, specialized optics and sophisticated signal processing improves the image formation process.
by 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 optics, sensors and processors to be jointly optimized...
