ABSTRACT:
A photographic camera (1) includes a back part (8) attachment that houses a charge-coupled surface sensor (9) and an associated filter system (11 and 13-17). The filter system includes a plurality of filters (13-16) positioned on a carrier (11). A motor (20) rotates the carrier (11) about rotational axis (12) such that individual filters (13-16) or cover disk (17) are positioned in front of the charge-coupled surface sensor (9). When the back part (8) attachment is mounted on the camera, the charge-coupled surface sensor (9) and one of the filters (13-16) lie in the beam bath from lens (3). Preferably, the lens (3) is interchangeable. Preferably, the individual filters (13-16) of the filter system are selected to break down incident light into primary colors (e.g., red, green, blue, and yellow). The cover disk (17) protects the charge-coupled surface sensor (9) when the back part (8) attachment is removed from the camera body (1).
