A Digital Photographic Data Processor and Display System.
Abstract
A digital picture processing system for extracting information from photographic film records was constructed and delivered. The system uses a Digital Video Converter that permits picture data transfer and display between a Digital Processor and a standard 525 line Television System. The Digital Processor has an 8000 word core memory and a Digital Tape Unit for storage and processing of digitized pictures. The Digital Video Converter stores a complete digital picture consisting of 384 x 489 picture elements on a magnetic disc. The picture elements, each having one of 256 possible shades of grey, are refreshed at standard television rates and are displayed in black and white on a television monitor or analyzed in a color television densitometer display. Television pictures of photographic transparencies are produced from a precision camera, digitized at an 8 MHz sampling rate and recorded on the disc for subsequent analysis by the Data Processor. Software for self-checking the system, transferring picture data and digitizing pictures was supplied with the equipment. (Author)
