"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)[reply]
