For displaying a selected zone of images belonging to a sequence of video images, each in the form of a matrix of pixels, on a display unit, a signal is generated by a fixed large-field camera having a definition that is greater than that of the display unit. A TV user or an operator at a control station selects a zone of format corresponding to that of the display unit in a field of view of the camera. The pixels of a modified image having the size and definition of the display unit are generated by interpolation from the pixels in the selected zone of the image supplied by the large-field camera. A device for implementing the method includes a module for warping the selected zone by operations of interpolation and resampling.
