Definition: A single dot on a computer display or in a digital image.
Definition: Short for Picture Element, a pixel is a single point in a graphic image. Graphics monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are so close together that they appear connected. The number of bits used to represent each pixel determines how many colours or shades of gray can be displayed. For example, in 8-bit colour mode, the colour monitor uses 8 bits for each pixel, making it possible to display 2 to the 8th power (256) different colours or shades of gray. On colour monitors, each pixel is actually composed of three dots - a red, a blue, and a green one. Ideally, the three dots should all converge at the same point, but all monitors have some convergence error that can make colour pixels appear fuzzy Also used in measuring image size and resolution, i. e. , 640 X 480 is the pixel resolution of most VGA Monitors. (Note pixels are square in computers and most digital cameras, they are rectangular in video cameras and television). The bit depth and surface size of the individual pixels on an image sensor controls its sensitivity to light. (Equivalent ISO).
Definition: Picture Element: digital photographs are comprised of thousands or millions of them; they are the building blocks of a digital photo.
Definition: Short for picture element. The smallest unit of a digital image that can be displayed, changed, or stored.
Definition: A term common in computer imaging referring to a picture element.
