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, and wherein
the at least three lenses pass light to the respectively assigned color filters that project the monochromatic images on pixel sensors of the respectively assigned pixel units, and corresponding pixel sensors for different monochromatic images are shifted against each other with reference to a reference point in the same scene or object imaged, so that the monochromatic images of the same scene or object captured by the pixel units are pixel shifted versions imaged from the deviating positions with respect to each other.
