LENS AND COLOR FILTER ARRANGEMENT, SUPER-RESOLUTION CAMERA SYSTEM AND METHOD

摘要

A lens and colour filter assembly contains lens units, and each lens unit is assigned to a single-colour colour filter unit. The lens and colour filter assembly may be combined with pixel units such that a plurality of monochromatic, low-resolution images can be obtained, and the monochromatic images refer to shifted versions of the same image object. By a super-resolution technique comprising shift-compensation a mosaicked image is obtained which is then demosaiced. In the resultant image only few artefacts appear. Simple colour filter arrays allow a simplified fabrication process and provide less chromatic aberrations at less computational effort.

1. A camera system comprising:
at least three lenses; at least three color filters, each color filter assigned to one of the at least three lenses; and at least three pixel units, each pixel unit being assigned to one of the at least three lenses, wherein the at least three pixel units capture monochromatic images of a same scene or object that are pixel shifted versions imaged from deviating positions with respect to each other, and that are to be fused to form a polychromatic image.
