ABSTRACT:
The invention relates to an apparatus for viewing a scene, especially for the reproduction thereon on the screen of a video monitor. This apparatus contains as usual a lens for projecting an image of the scene on a focal plane, and a video pickup lying in this focal plane for converting the brightness, and if necessary the hue, of individual points of the picture into electrical signals. To view a section of the scene or for recording, viewing and, in some cases, following a selected subject within the scene the video pickup is mounted in accordance with the invention for displacement in the focal plane over the entire image and is smaller than the image projected in the focal plane. The video pickup is furthermore coupled with a drive mechanism which contains drives acting in different directions. Another drive can serve to rotate the video pickup.
