PURPOSE:To take easily the picture of a movable subject by providing a subject- image formation part and a distance-measuring subject-image formation part to the photo detection surface of a pickup unit, by forming a subject image by object lenses and by forming a distance-measuring subject image by an optical system for measurement at the same time. CONSTITUTION:In the TV camera which obtains a video signal by forming a subject image on the photo detection surface of the pickup unit while obtaining a distance-measurment signal by forming a distance-measurement subject signal by the optical system for distance measurement, object lenses 1, 2 and 10 form the subject image at subject-image formation part 19 sectioned in the horizontal scan direction on pickup surface 18 on the surface 17 of pickup tube 9. Further, optical systems 11 to 16 for distance measurement form distance-measurement subject images at measurement subject-image formation parts A and B of pickup surface 18. In the period from the end of the 1st scan on the image formed at subject-image formation part 19 until the start of the 2nd scan on the image formed at subject-image formation part 19, images at measurement subject-image formation parts A and B are scanned. |
