Image-Quality Criteria for Data Recording and Storage
Quality criteria for photographs used for the recording and storage of information are reviewed on the basis of the signal-to-noise ratio (SNR) of the image, which is defined and illustrated. Concepts discussed include the following: resolving power from the standpoint of SNR; the minimum detectable increments of both density and exposure; errors produced in the readout by film granularity; the information capacity of the emulsion; informational sensitivity; and detective quantum efficiency.
