<title>Recorder Video Processing For Image Enhancement</title>

Abstract

The overriding problem in airborne video recording is the preservation of image quality in the reproduced display. Techniques have been developed to maintain and enhance image quality for video kinescope recorders by electronic processing of the video signal. These techniques may be utilized during the recording phase in the interface between the data source and video recorder, and/or during the reproduction phase in the interface between the recorder and display. The image characteristics effected, and the methods of enhancement are described herein, including gamma correction, auto-matic contrast control, black and white level control, aperture correction and bandwidth equalization. Performance characteristics of hardware in which these techniques have been implemented are presented.© (1973) COPYRIGHT SPIE--The International Society for Optical Engineering.
