Megapixel

Megapixel is the short form of One Million Pixel (1000000 pixels). Pixel is the Unit of an image file; a single dot (with existing image information). A Megapixel image can be in any shape. It is actually counted from multiplying Image’s Width (horizontal) and Height (vertical) (e.g. 1000 x 1000, 1200 x 834 etc). More Megapixel means bigger size and more detailed image.
