Though technically inaccurate, the term resolution in the world of mobile phone displays and digital cameras refers to the number of columns and rows of pixels. A display with 240 pixel columns and 320 pixel rows would generally be said to have a resolution of 240x320. Resolution can also be used to refer to the total number of pixels in a digital camera image. For example, a camera that can create images of 1600x1200 pixels will sometimes be referred to as a 2 megapixel resolution camera since 1600 x 1200 = 1,920,000 pixels, or roughly 2 million pixels. Some display and camera resolutions have special names, such as VGA, QVGA, CIF, and QCIF.
