A camera system includes lens units such that 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 that includes 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.

Lens and color filter arrangement, super-resolution camera system and method

A camera system () comprises a plurality of imaging units (), wherein each imaging unit () includes a lens unit () and an aperture unit (), and wherein the apertures () of the aperture units () have different size during an exposure period. A plurality of images of the same scene are captured at different aperture sizes during an exposure period, wherein the images are shifted versions of the scene and feature different depth-of-field and exposure value ranges. A processing unit () applies a high-dynamic resolution and/or a super-resolution method on the basis of the obtained images.
