Abstract

A camera system (100) comprises a plurality of imaging units (190), wherein each imaging unit (190) includes a lens unit (120) and an aperture unit (110), and wherein the apertures (115) of the aperture units (110) 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 (200) applies a high-dynamic resolution and/or a super-resolution method on the basis of the obtained images.
