Film scanner system for reducing scratch visibility by collecting scattered light

A film scanner, such as a telecine, includes a light source 1, collection optics 2 and one or more light sensors 7,10,12 to produce image signals representative of an image on film 3. In addition, a reflector arrangement 15 is provided which has an internally reflective cavity, such as an integrating sphere, to capture light which may have been scattered from the usual light path and provided to an additional sensor 16. Compensations can thus be made for light scattered in any direction, using adding correction circuits (see Figures 3,4 and 5). Such circuits sum a function of the scattered light received by sensor 16 with one or more of the image signals from sensors 7,10,12 to compensate the image signals.
