ABSTRACT:
An object of this invention is to reduce level differences and errors in a luminance signal and color difference signals. In order to achieve the above object, an image pickup apparatus has an image sensor for photoelectrically converting an object image and a plurality of delay lines for delaying a video signal by one horizontal period, so that a video signal derived from an output including a clock leakage component from the image sensor is input to the plurality of delay lines, including an adjustment unit for adjusting the signal level of the video signal at an input or output of at least one of the plurality of delay lines.
