![]() Software on early consumer computers was necessarily rendered at a low resolution, with large pixels visible to the naked eye graphics made under these limitations may be called pixel art, especially in reference to video games. In some contexts (such as descriptions of camera sensors), pixel refers to a single scalar element of a multi-component representation (called a photosite in the camera sensor context, although sensel is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position. ![]() In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In most digital display devices, pixels are the smallest element that can be manipulated through software.Įach pixel is a sample of an original or synthetic image more samples typically provide more accurate representations of the original. In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device. This example shows an image with a portion greatly enlarged so that individual pixels, rendered as small squares, can easily be seen. For other uses, including for the plural form "pixels", see Pixel (disambiguation). This article is about the picture element.
