Abstract
The basic function of an image source is to represent the distribution of light energy in an ‘image’ as an electronic signal which may be communicated to a computer for storage and subsequent analysis or enhancement. Thus a two-dimensional light intensity function f(x,y) ultimately undergoes conversion to an array of numbers representing light amplitudes at a set of points. The output of the source is usually a unidimensional, time-varying signal v(t) which results from the process of scanning as described in Chapter 5. Application areas for image processing are very wide (ranging from microscopy to astronomy) and source types are correspondingly varied.
