To define a image we need to use the two dimensional method, this method is known as the f(x,y). x and y in the function represent the simple plain coordinates called spatial. Gray level of image or intensity at that point is amplitude of 'f' at any pair of coordinates (x,y). A image is called digital when fine value of coordinates x,y and the amplitude of 'f' are together. When a digital image in the digital computing processed by a digital computer this term is called the digital image processing. Finite numbers of elements composed a image, and each this element have specific values and location. These element are known as picture elements, pixels, pels and image elements. the element that is mostly used to denote the digital image is Pixel.
There are two principal application related areas that build the digital image processing methods. First is graphic information improvement for human interpretation. Second is the processing of image data for storage, transmission, and representation for autonomous perception.

Digital images was used first in newspaper industry, In earlier time the images was sent from the submarine cable from one country to another country. At that time a image take couple of hours to send across the Atlantic. Now days we send and receive images within the milliseconds across the thousands of miles. Event we can now send and receive files from the satellites place in millions of miles distance in milliseconds. Digital image first commercially used in communication in the telegraphy system. These are the telegraph half tone black and white pattern image.
