TL;DR: In this paper, an image processing system which receives asynchronous analog video output signals from a plurality of independently operating video cameras (preferably four) and simultaneously displays the image obtained from each camera, dimensionally reduced by a factor of two, on a non-overlapping basis on one video monitor is described.

03 Oct 1985TL;DR: In this paper, an optical switching system for generating video signals using an improved camera system is described. But the camera system includes first and second video imaging devices which are scanned at different scan rates and makes efficient use of available light from a scene being imaged.
Abstract: An apparatus and method for generating video signals using an improved camera system is disclosed. The camera system includes first and second video imaging devices which are scanned at different scan rates. An optical switching system directs light from the scene alternately in time to the first and second video imaging devices, and makes efficient use of available light from a scene being imaged. In an embodiment of the invention, the optical switching system includes a reflective shutter.

13 May 1985TL;DR: In this paper, an automatic light level control system for a video camera is described, which uses a time-variable camera clock for determining and controlling the scanning rate of the camera.
Abstract: An automatic light level control system for a video camera is disclosed which uses a time-variable camera clock for determining and controlling the scanning rate of the camera. A control means responsive to the light level of the video output of the camera controls the rate of the camera clock, and thereby the scan rate of the camera so that the light level of the video output is maintained within desired limits.

TL;DR: The electronic still camera is a new concept in cameras, which uses solid state imagers to convert the light from the object into picture information in the form of electrical signals which are stored on a video floppy inside the camera.
Abstract: The electronic still camera is a new concept in cameras, which uses solid state imagers to convert the light from the object into picture information in the form of electrical signals which then stored on a video floppy inside the camera.

TL;DR: In this paper, an approach for monitoring the field of view observed from the interior of a road vehicle consisting of a base structure 1a for support by a front seat within the vehicle, a pair of video cameras (36a) 36b carried by the base structure, and a V.D.U. (not shown) for monitoring video cameras observed by the video cameras.
Abstract: Apparatus for monitoring the field of view observed from the interior of a road vehicle comprises a base structure 1a for support by a front seat within the vehicle, a pair of video cameras (36a) 36b carried by the base structure, and a V.D.U. (not shown) for monitoring the field of view observed by the video cameras. The video cameras may be placed side by side, in a binocular-like manner or, alternatively, one above the other so as to monitor different fields of view. When placed side by side, the video cameras are movable in a substantially horizontal plane, so as to simulate eye movement of the occupant of the front seat of the vehicle, and the direction of view may be measured on a protractor 41 imaged by one or other camera via beam splitter 44. The ion displays the image from a selected camera.

TL;DR: In this paper, the arrangement for angiographic recording using a video recorder comprises a fundus camera (11) for illuminating the retina of the eye (39) to be examined and for forming an image of the illuminated retina.
Abstract: The arrangement for angiographic recording using a video recorder comprises a fundus camera (11) for illuminating the retina of the eye (39) to be examined and for forming an image of the illuminated retina. Secured rigidly to the housing of the fundus camera (11) is the housing of a video camera sensitive to low light, and inserted between the output side of the lens (41) of the fundus camera (11) and the input side of the lens (19) of the video camera (13) is a ray path connector (21) optically connecting these two lenses.
