Abstract

A lens and color filter assembly contains lens units, and each lens unit is assigned to a single-color color filter unit. The lens and color 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 artifacts appear. Simple color filter arrays allow a simplified fabrication process and provide less chromatic aberrations at less computational effort.
