"megapixels"
Note that it has become fashionable in camera marketing to count the red, green, and blue channels are 3 pixels. So a 15 MP sensor may be called 45 MP, even though it only has 15 million picture elements of spatial resolution. This is not the definition used by image processing and graphics experts.

 * The pixel article discusses this to some extent. Typically, in cameras, each individual photodiode is counted as a pixel.  In graphics, an RGB triple is a pixel.  In displays, it varies.  Dicklyon (talk) 23:35, 20 December 2014 (UTC)
