ABSTRACT:
A device for processing color data (R, G, B) of a signal representing an image. The processing device has a mechanism which, for each color data item, consist of an analog/digital converter (12, 13, 14) and a buffer memory (MT1, MT2, MT3), a circuit (PT) for processing the digital data output by each buffer memory, and serializer circuits (SE1, SE2, SE3) which collect the signals output by the processing circuit (PT) and make it possible to generate signals (D1, D2, D3) intended to reproduce the image with a slow-motion effect. According to an improvement of the invention, the control unit includes a mechanism (MO, SE4) for generating a signal (I) making it possible to reproduce the image at normal speed. The device applies particularly to television studio cameras in the professional sector.
