Abstract

Abstract Digital still cameras, DSCs, now provide the overwhelming source of images from consumers, commercial enterprises, graphic arts, movies, scientific imaging, and medical imaging. The mobile or smart phone cameras are starting to dominate the lower end market. In any case, the vast majority of digital cameras need to produce a color image. This chapter will provide a basic understanding of the CIE (International Commission on Illumination) color system and how it is applied to digital color images. The sometimes complex relationship between the basic optics, the color filter array, CFA, the CMOS (complementary metal oxide semiconductor) or CCD (charge‐coupled device) sensor, the quantum efficiency, QE, of the sensor and a range of image processing techniques to provide a range of color renderings will be discussed in detail with many examples.
