Abstract
An endoscope apparatus is disclosed in which the horizontal transfer of the charge of a solid imaging device such as a CCD and the resetting for the detection of the charge are conducted by a common drive signal. The signal transmitted from the solid imaging device is caused to contain a feed-through period by making the drive signal to be served by a multi-valued level horizontal transfer signal exceeding a trinary value. Therefore, reset noise or the like can be eliminated by processing the output signal by using a correlated double sampling circuit or the like so that a video signal exhibiting a good S/N ratio can be obtained.
