Our online glossary is here to help you make sense of the terminology used in the cell phone industry.

What is "resolution"?

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.
