A METHOD AND A SYSTEM FOR OPTICAL DESIGN AND AN IMAGING DEVICE USING AN OPTICAL ELEMENT WITH OPTICAL ABERRATIONS

摘要

A method and a system for optical design and an imaging device using an optical element with optical aberrations are provided to apply algorithm correction to an initial image which is not corrected, thereby outputting a final image having preset mapping without respect to optical aberration's influence. A photographing apparatus(450) comprises an image sensor(453), an optical unit(451) and an optical algorithm correction module(452). The optical unit projects the initial image on the image sensor by optical aberrations. The optical algorithm correction module is connected to the image sensor. And the optical algorithm correction module compensates the influence of the optical aberrations influencing the initial image according to at least one parameter defined by the optical aberrations to output a final image having preset mapping to which any influence of the optical aberrations is not applied.
