ABSTRACT:
Television camera for picking-up a scene and for producing a signal for an image therefrom, a portion of which has an increased resolution. At its input the camera is provided with a lens which produces an image of the scene on the input face of an anamorphic lens which distorts the image in accordance with a predetermined law in a given direction, the lens co-operating with a bidimensional charge-transfer pick-up device. This device detects the distorted image supplied, and includes an output shift register which is read by means of a clock whose rate is programmed as a function of the predetermined law so that the signal supplied by the charge-transfer device renders it possible to recover a final image which is no longer distorted, and which has a different resolution in different portions of the image. The image may be progressively or uniformly distorted into one direction in a certain portion of the image.
