Abstract
An endoscope apparatus has a clamp circuit that clamps an image pickup signal that is obtained by picking up of an image with a CCD at timing that is specified with an optical black pulse, an image processing section that applies various kinds of signal processing to the image pickup signal that is outputted from the clamp circuit to convert the image pickup signal into a video signal, and a timing generator and a control section that change a phase of the optical black pulse in response to a kind of an endoscope or a length of an insertion portion.
