Abstract:
1. A head separation type camera comprising: a camera head provided with an image pickup device and camera control unit to which the camera head is connected; wherein the camera control unit comprises: a CDS circuit that performs co-related double sampling on an output signal of the image pickup device in accordance with an input pulse; a phase adjusting unit that performs phase adjustment of a clock signal and outputs an adjusted clock signal being performed with the phase adjustment; a pulse output unit that generates a sample pulse being adjusted with a phase thereof in accordance with the adjusted clock signal being input from the phase adjusting unit; a peak search unit that performs a search for a peak range with respect to a signal output from the CDS circuit; and a phase control unit that controls the phase adjustment of the clock signal in the phase adjusting unit so as that the phase of the sample pulse generated by the pulse output unit becomes within the peak range being searched by the peak search unit.
