In agenda imaging, a pixel, or pel,1 (picture element2) is a distinct point in a raster image, or the aboriginal addressable awning aspect in a affectation device; it is the aboriginal assemblage of account that can be represented or controlled.
Each pixel has its own address. The abode of a pixel corresponds to its coordinates. Pixels are commonly abiding in a two-dimensional grid, and are generally represented application dots or squares. Anniversary pixel is a sample of an aboriginal image; added samples about accommodate added authentic representations of the original. The acuteness of anniversary pixel is variable. In blush angel systems, a blush is about represented by three or four basic intensities such as red, green, and blue, or cyan, magenta, yellow, and black.
In some contexts (such as descriptions of camera sensors), the appellation pixel is acclimated to accredit to a distinct scalar aspect of a multi-component representation (more absolutely alleged a photosite in the camera sensor context, although the neologism sensel is sometimes acclimated to call the elements of a agenda camera's sensor),3 while in others the appellation may accredit to the absolute set of such basic intensities for a spatial position. In blush systems that use blush subsampling, the multi-component abstraction of a pixel can become difficult to apply, back the acuteness measures for the altered blush apparatus accord to altered spatial areas in a such a representation.
The chat pixel is based on a abbreviating of pix ("pictures") and el (for "element"); agnate formations with el for "element" accommodate the words voxel4 and texel.4
