Abstract
Television camera lenses cover a field which is larger than the useful field to be televised. Defects appear in the useful image as a result of diffusion of light from the portion of the image which is not intended to be televised or in other words the peripheral portion. The device for correcting peripheral diffusion comprises scanning and processing means for scanning a band located on the target around the image to be televised and for supplying a diffusion-correcting signal which is representative of a mean value of the band-scanning signals.
