A Technique for Anticipating in-the-Field Performance of Low Light Level Television

Abstract

The basic assumptions and relationships used in converting low light level TV laboratory-measured performance data to anticipated “real-world” performance data are set forth. How visual range (distance) can be determined for specific low light level conditions, the effects of factors such as target size, requirements for recognition, scene reflectance, contrast, f/number, transmission, field of view, atmospheric effects, and by camera movement or image motion are discussed briefly in regard to the performance predictions.
