1 March 1991 Standards for image input devices: review and forecast
Author Affiliations +
Terms such as resolution, sensitivity and signal-to-noise ratio are often discussed by vendors and users without clear understanding by either party of just what they mean. These terms were already difficult enough to understand and apply when only RS-170 scanning was in broad use and when video was obviously an analog signal produced by a vidicon image tube.

Now, with a multiplicity of scanning modes in use, digital video transmission of many different formats and rates and an enormous variety of image sensing devices, both tube and monolithic, available, the need for a common vocabulary, universal test methods and a set of broadly-applicable interface specifications in the optical, mechanical and electronic domains is badly needed.

In this review, we will summarize current efforts to produce appropriate standards documents, assess the progress of these efforts, recommend priorities which might be followed to maximize early utility and identify additional standards efforts which should be undertaken.
