Abstract:
An aspect ratio and scan converter system adapts signal information derived from optical scanning of a rectangular field of view having an aspect ratio of the order of 60 to 1. The signal information is converted to digital form and serially stored in a bulk storage memory which may be addressed for reading out selected sequences of the serially stored digital signals. The selected sequences are stored in a random access memory having a two dimensional format and then read out by repetitive scan in a direction orthogonally related to the direction in which the sequences were stored. The digital signals thus read out are converted to analog form and applied to a suitable display means such as a TV type monitor CRT, providing a visual display of the selected portion of the elongate field of view.
