What is a megapixel on a camera? |
A million pixels
A megapixel is one million pixels. A pixel is a picture element. Like graphics displayed on a television or computer monitor, digital photos are made from millions of tiny colored dots, or pixels. The more pixels used to produce a photo, the less "grainy" it will appear and the better any enlargements made from it will be.
A 6-megapixel camera can produce standard 4 x 6 photos at a remarkable 500 pixels per inch and 8 x 10 photos at 273 ppi.
A megapixel (MP) is 1 million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.
