6Impacts of Digitization by Built-In Coordinate Points on Image Information Quality

Chapter 1 described the factors that compose image information (light intensity, space [position], wavelength, time) and how all factors except light intensity are built-in coordinate points in imaging systems. Image sensors measure the number of photons entering the domain of each built-in coordinate point. This means that sensors integrate the signal charge generated when an incident photon reaches three territories of each coordinate point, that is, at each pixel area, through each color filter, and during the exposure period of each frame. This operation is known as sampling of photon numbers at each coordinate point. This chapter discusses the impacts of ...
