The pillarbox effect occurs in widescreen video displays when black bars (mattes or masking) are placed on the sides of the image. It becomes necessary when film or video that was not originally designed for widescreen is shown on a widescreen display, or a narrower widescreen image is displayed within a wider aspect ratio , such as a 16:9 ...
The term "SmileBox" is a registered trademark [4] used to describe a type of letter-boxing for Cinerama films, such as on the Blu-ray release of How the West Was Won.The image is produced by using a map projection-like technique to approximate how the picture might look if projected onto a curved Cinerama screen.
These bars have been used to censor various parts of images.

A drawback of pixelization is that any differences between the large pixels can be exploited in moving images to reconstruct the original, unpixelized image; [ 3 ] squinting at a pixelized, moving image can sometimes achieve a similar result.
In letterboxing, the top of the image is slightly lower than usual, the bottom is higher, and the unused portion of the screen is covered by black bars. For video transfers, transferring a "soft matte" film to a home video format with the full frame exposed, thus removing the mattes at the top and bottom, is referred to as an "open matte transfer."
They therefore often encode content as just the active frame, without any aspect ratio adjustment bars (letterbox or pillarbox bars). Movies with a 2.39:1 aspect ratio are a natural match for 21:9 output video timings, as long as the streaming clients support such video modes, and even content with other wide aspect ratios such as 2.00:1 and 2. ...
