Abstract
The camera has a solid-state image sensor (FTD) comprising a pick-up member (I), a storage member (M) and a shift register member (SR) having three output shift registers (SR1, SR2, SR3). The picture signals (S1, S2, S3) originating from the output registers must be combined in a monochrome camera or a color camera with several image sensors to form a balanced composite picture signal (S0). To this end, the camera comprises a control system for fixing one and the same black level in the three picture signals. Via the control system including a common differential amplifier (AM) and multiplex (MUXa, MUXb) and demultiplex circuits (DEMUX), signal reset levels are fixed in the three picture signals (S1, S2, S3) with the aid of peak rectifier circuits (PR1, PR2, PR3) in such a manner that more or less the same signal black level occurs in the picture signals.
