Definition: A pixel, short for picture element, is the smallest piece of information that makes up a digital image.
Individual pixels are tiny dots, squares, or rectangles. A digital photograph consists of millions of pixels, but the individual pixels are too small to see without magnification. The human eye naturally blends all of the pixels together to create what appears to be a seamless image.
Pixels also make up the LCD screen on the back of the digital camera. LCDs with more pixels create sharper images.
Also Known As: picture element
