Abstract: A document processing system including a video camera and raster scan television monitors. The apparatus comprises a document transport that sequentially passes documents by both a machine readable data reader and a video camera. The data reader reads and stores in a digital memory the machine readable data encoded on the documents. The video camera captures the entire image of each document and stores the images in a video memory. In one embodiment the images are stored as analog signals and in another embodiment as digital signals. The system further includes a plurality of video terminals at which the operators of the system can recall and display on command both the machine readable data and the video images of the documents.

Abstract: A document storage and retrieval system featuring a plurality of remotely disposed control terminals arranged in data transfer relation to a computer includes a plurality of document storage units containing documents recorded on film. These units include means for converting an optical image of such documents to video signals. A plurality of video buffer units associated with each of the terminals are coupled by switching means to any one of the document storage units so that the video signals derived therefrom and representing the documents can be stored on a video buffer unit associated with a given terminal.

Abstract: An image registration system for a video camera is used in an optical information retrieval system in a manner to accurately register a pre-recorded image relative to the target of a T.V. camera. A light responsivearray defines the outline of an area corresponding in size and shape to that of the target and the image is simultaneously projected upon both the target and the light responsive array.In the event that the image is off-center with respect to the target, the light responsive elements serve to generate control signals for operating servo motors connected to mirrors for readjusting the light path along each of two predetermined axes. This movement causes the image (which is either transmitted to a monitor or which is later scanned from the target and recorded on a magnetic recording medium or the like) to be precisely centered or otherwise disposed at a predetermined position.
