PHN. 11 401 21 ABSTRACT: A camera for recording television, photographic or cinematographic images comprises an automatic focusing device (18, 22). The information required therefor is obtained with the aid of a partial blocking arrangement (5, 6, 9) for blocking two different portions of an optical path (7) leading to an opto-electronic sensor (1), these two portions being located mutually opposite on either side of an optical central axis. After signals obtained during the partial blocking periods have been compared with each other, the focusing position is adjusted until an optimum signal correlation is obtained. To realize a camera having both an undisturbed scene recording and an automatic focusing operation, whilst using only one sensor (1), this camera is in the form of a charge transfer device comprising a pick-up member (P), a storage member (M) and a shift register member (SR) and is operative during a television field period TV in the following sequence: scene - pick-up period TVS, pick-up storage transfer period TFO, first partial block- ing pick-up period TAS, first pick-up storage transfer period TF1, second partial blocking pick-up periods TBS and second pick-up storage transfer period TF2, either the sequence TVS, TFO, TAS and TF1 or TVS, TFO, TBS and TF2, as the case may be.
