In digital imaging, a pixel, pel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. The address of a pixel corresponds to its physical coordinates. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates.

Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image 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 some contexts (such as descriptions of camera sensors), the term pixel is used to refer to a single scalar element of a multi-component representation (more precisely called a photosite in the camera sensor context, although the neologism sensel is sometimes used to describe the elements of a digital camera's sensor), while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in such a representation.

A pixel is the base element of a digital image in computer graphics.

Pixels is a 2015 American science fiction action-comedy film produced by Columbia Pictures, 1492 Pictures and Happy Madison Productions. The film was directed by Chris Columbus. Its screenplay was written by Tim Herlihy and Timothy Dowling, with a screen story penned by Tim Herlihy and based on French director Patrick Jean's 2010 short film of the same name. The film features computer animated video games characters, special effects, and stars Adam Sandler, Kevin James, Josh Gad, Peter Dinklage, Michelle Monaghan, Brian Cox, Ashley Benson, and Jane Krakowski. The film's plot has extraterrestrials misinterpreting video-feeds of classic arcade games as a declaration of war, and invading Earth using technology inspired by games such as Pac-Man and Space Invaders. To counter the alien assault, the United States hire former arcade champions to lead the planet's defense.

Principal photography on the film began in 2014 in Toronto, Ontario, Canada. It was released in 2D, 3D, and IMAX 3D in 2015. The film had a production budget of $88 million, with print and marketing bringing it to a total cost of around $145 million. The worldwide gross was $244 million. Despite receiving generally negative reviews, the movie was a commercial success.
