摘要

In a video camera having an image pick-up section (22) and a signal processing section (21) to which an output signal from the image pick-up section (22) is supplied through a transmission cable (23), there are provided in the image pick-up section (22), an image pick-up device (26) and reference signal adding means (28, 29) for adding a reference signal (e.g. the horizontal transfer clock (HS min ) applied to the image pick-up device (26)) indicative of the position of a reference pixel of the image pick-up device (26) in a predetermined interval (e.g. during a line interval of the vertical blanking period (VB)) of an output video signal of the image pick-up device (26), and there is provided in the signal processing section (21) extracting means (36 to 40) for extracting the reference signal from a signal which is supplied from the image pick-up section (22). <IMAGE>
