Abstract
An imaging apparatus includes: a camera head that is provided with an image pickup device that outputs an image signal; a camera control unit that is connected to the camera head with a camera cable and outputs a video signal based on the image signal; a CDS circuit that performs co-related double sampling on the image signal; a pulse generator that outputs sample pulses to the CDS circuit; a phase adjusting unit that performs phase adjustment on a clock signal and outputs the adjusted clock signal to the pulse generator; a peak search unit that searches for a peak range in the image signal being performed with the co-related double sampling by the CDS circuit; and a phase control unit that controls the phase adjustment by the phase adjusting unit based on a result of the search by the peak search unit.
