How Digital Images are Created

Have you ever wondered how:
  • digital images are created?  The digital images are rectangular arrays of pixels. Each pixel is represented in regular charge coupled device (CCD) chip by recording the brightness value. 
  • black and white images are created? A black and white image, mathematically, is a single matrix of numbers from 0 to 255. 

  • color images are created? Color images are represented by three matrices of RGB (red, green and blue).
