<p>An exchangeable connecting device between a video camera (M5) such as a CCD (Charged Couple Device) camera, area image sensor and automatic iris lens; in said video camera (M5) one of video control signals (1) amplified the output of light sensor is directly connected to an analogue switch (t), while the other is connected through a galvanometer control circuit (p) to the analogue switch (t), said analogue switch (t) being connected to one common connector (k). When VS control type automatic iris lens (L1) is connected to the connector (k), a video control signal (1) amplified the output of light sensor is directly connected to the analogue switch (t) and the common connector (k). When a DC control type automatic iris lens (L2), said analogue switch (t) is switched and a video control signal (1) is amplified by said galvanometer control circuit p, so that the output of the light sensor is connected to one common connector (k) as a control current (2) of a galvanometer (f) corresponding to a video signal (IVpp). <IMAGE></p> |
