This article is about the picture element. For other uses, see Pixel (disambiguation).
This example shows an image with a portion greatly enlarged, in which the individual pixels are rendered as little squares and can easily be seen.
A pixel (short for picture element,[1] using the common abbreviation "pix" for "pictures") is a single point in a graphic image. Each such information element is not really a dot, nor a square, but an abstract sample. With care, pixels in an image can be reproduced at any size without the appearance of visible dots or squares; but in many contexts, they are reproduced as dots or squares and can be visibly distinct when not fine enough. The intensity of each pixel is variable; in color systems, each pixel has typically three or four dimensions of variability such as red, green, and blue, or cyan, magenta, yellow, and black.
