A video processor for endoscopic camera or for videoendoscopic probe associated with a color video sensor, the video processor comprising: a signal preprocessing circuit designed to be remotely connected to the video sensor through an electrical link without any intermediate connection device, the preprocessing circuit comprising a first signal processor for generating from image signals output by the video sensor raw video signals comprising a brightness signal and a color signal, these signals being not usable directly because they are phase shifted and are noisy due to synchronization residues, and a synchronizing circuit for synchronizing the video sensor and the first signal processor; and a remote auxiliary circuit comprising a second signal processor connected to the first signal processor through a low impedance electrical link providing good immunity to interference, the second signal processor generating from said raw video brightness and color signals at least one useful video signal according to an international video standard.
