Pixel World Pixel: The minute area of illumination on display screen, one of many image is composed. Usage: Taking an example,Camera captures the data, line to line from top to bottom in a single click. In projection, cathode ray tube fires the electrons according by line to line from top to bottom on pixel elements. Each pixel elements contributes to final image.
