megapixel

One million pixels. The measurement of the resolution of still and video cameras, monitors and scanners. For example, a 16-megapixel (MP) still camera captures a picture composed of some 15.9 million pixels, each pixel containing a red, green and blue color dot. The image resolution would be 5312x2988: 5,312 pixels across; 2,988 down.

The Megapixel Myth
Because quantity is easier to measure than quality, numbers reign supreme in the high-tech world, and megapixels are no exception. Although the number of megapixels is important, particularly if an image is going to be cropped, the quality of the camera's lens, sensor, zoom capability and processing circuitry is equally meaningful but difficult to express in writing. The only true measure is hands-on. See MPps, pixel, digital camera features and DPI.
