ABSTRACT:
A camera unit is composed of a first camera for photochemical image reproduction and a second, electronic camera. The first camera is provided with a first lens having a first image registration region. The image which is projected onto image plane of the first camera corresponds to the first image registration region. The electronic camera is provided with a second lens whose optical axis is displaced relative to the optical axis of the lens of the first camera. The image registration region of the electronic camera, and thus also of the image projected on its image plane, differs in image content from the image content of the first camera due to the parallax which the displacement causes. A control device is provided for processing an electrical signal received from photosensitive elements contained in the electronic camera. This processing is carried out in accordance with the output of sensors, which generate signals representing the state of the lens of the first camera with respect to focal length and focussed distance, which determine the size of the parallax. The photosensor elements comprise the image lane of the electronic camera. Those photosensor elements which register the image registration region of the photochemical camera are then determined. An output signal is composed for reproduction and/or storage of an image corresponding to the image which the first camera is set to capture on its image plane.
