PHN 11.411 17 21-04-1986 ABSTRACT: "Camera for recording television, photographic or cinematographic images." To realise a camera with both an undisturbed scene recording and automatic adjustments which are periodically effected while using one and the same image sensor (1), this sensor is formed as a charge transfer device comprising a pick-up member (I), a storage member (S) and a shift register member (SR). To perform a black level setting (9, 11) in the scene picture signal an opaque strip (BS) is provided on the pick-up member (I). Automatic adjustments for, for example, lens focus (FC) and white balance (WB) in colour recording are accurately performed when the image sensor, beyond a scene picture information integration period and a subsequent charge transfer period between pick-up member and storage member, is operative with an adjustment action information integration period and a subsequent charge transfer period so that a signal is obtained at the sensor output terminal (R,G,B) with sequentially the adjustment action information and the associated dark current information for a separate black level control circuit (10, 12). The adjustment action information can thereby be accurately determined for the relevant adjustment as the own dark current information is automatically obtained. Fig. 1.
