DETERMINATE AND INDETERMINATE OPTICAL SYSTEMS

摘要

An optical system (302) has a plurality of optical surfaces (304, 305, 306, 307, 308, 309) configured to provide blurred images of objects located within a selected range of object distances. At least two of the plurality of optical surfaces are configured to contribute to the blurring. An imaging system (300) includes a blurring optical system (302), a sensor (310) which receives light directed through the optical system, and an image processor (320) which selects one or more deblurring functions and applies the deblurring functions to provide a processed image. The processor may apply different deblurring functions to different sets of the raw data representing different portions of the field of view.
