摘要

The invention is related to a circuit arrangement of a single-tube colour camera with a receiving device. It is the object of the invention to achieve increased resolution in document mode compared with colour video telephony. According to the invention, the object is achieved by the fact that a branch II which is used for processing a composite video signal is connected in parallel with a known branch I for processing a composite colour video signal.
