What Are Megapixels?

By

Definition:

A Megapixel is a unit of measurement which represents one million pixels — those tiny dots of color which make up an image.

Practically speaking, Megapixels represent the resolution, or size and quality, of an image, or an image capturing device such as a web cam or digital camera. The higher the number of Megapixels a camera can capture, the higher quality the images it produces will be.
