PHOTOGRAPHIC SYSTEM USING CHROMA-KEY PROCESSING

A photographic system 1 comprising a digital still camera 3 for producing an output signal, means 11 for processing the output signal with a pre-recorded picture signal to produce a revised image signal and means 13 for printing the revised image, wherein the means 11 for processing uses chroma-key processing 37,39 to insert a background picture signal into a key color-characterized region of a foreground picture signal The invention results in a novel application of chroma-key processing to produce good quality still photographs using a simple and robust system.
