Impairments in imaging systems are discussed in the areas of lens vignetting, camera spectral sensitivities, reproduction gamut, tone reproduction, luminance-chrominance coding, and spatial resolution. The causes of these impairments are reviewed, and their importance discussed. Means of providing corrections are considered, and the factors determining whether such means are used or not, are reviewed; the type of scene being imaged is shown to be decisive in many cases.
