Colour video camera of the single-tube type. It includes a permanent memory 30 in which are stored, in digital form, the corrective information for the various zones of the sensitive surface of the picture pick-up tube. The address input 32 of this memory receives address signals which correspond to the various zones of the sensitive surface so that the corrections are synchronised with the scanning. These corrections are: spot corrections acting on the colour signals, the linearity signals and the static and dynamic focusing signals. <IMAGE>
