'''Parallax scrolling''' is a technique in [[computer graphics]] where background images move past the camera more slowly than foreground images, creating an illusion of depth in a [[2D computer graphics|2D]] scene of distance.<ref>{{cite news|title=Cap.

Parallax scrolling was popularized in [[2D computer graphics]] with its introduction to [[video games]] in the early 1980s. Some parallax scrolling was used in the [[arcade video game]] ''[[Jump Bug]]'' (1981).<ref name=purcaru>{{cite web|url=https://books.google.com/books?id=lB4PAwAAQBAJ&pg=PA181|title=Games vs. Hardware. The History of PC video games: The 80's|first=Bogdan Ion|last=Purcaru|date=13 March 2014|publisher=Purcaru Ion Bogdan|via=Google Books}}</ref> It used a limited form of parallax scrolling with the main scene scrolling while the starry night sky is fixed and clouds move slowly, adding depth to the scenery. The following year, ''[[Moon Patrol]]'' (1982) implemented a full form of parallax scrolling, with three separate background layers scrolling at different speeds, simulating the distance between them.<ref>{{cite book |last1=Uduslivii |first1=Igor |title=iPhone Game Blueprints |date=26 December 2013 |publisher=[[Packt Publishing Ltd]] |isbn=978-1-84969-027-0 |page=339 |url=https://books.google.com/books?id=C5R4AgAAQBAJ&pg=PT339}}</ref> ''Moon Patrol'' is often credited with popularizing parallax scrolling.<ref>{{cite web|title=Chronology of the History of Video Games: Golden Age|url=https://www.thocp.net/software/games/golden_age.htm|first=Ted|last=Stahl|date=2006-07-26|access-date=2009-07-06|archive-url=https://web.archive.org/web/20090716033610/http://www.thocp.net/software/games/golden_age.htm|archive-date=2009-07-16|url-status=live}}</ref><ref>{{cite web|url=https://www.gamesradar.com/f/gamings-most-important-evolutions/a-20101008102331322035/p-3|title=Gaming's Most Important Evolutions|page=3|publisher=[[GamesRadar]]|date=October 8, 2010|access-date=2011-04-27}}</ref> ''[[Jungle Hunt|Jungle King]]'' (1982), later called ''Jungle Hunt'', also had parallax scrolling,<ref>{{cite web|title=Jungle Hunt Was a Terrible Waste of Quarters|url=http://retrovolve.com/jungle-hunt-was-a-terrible-waste-of-quarters/|access-date=2015-03-27|archive-url=https://web.archive.org/web/20150402132140/http://retrovolve.com/jungle-hunt-was-a-terrible-waste-of-quarters/|archive-date=2015-04-02|url-status=live}}</ref> and was released a month after ''Moon Patrol'' in June 1982.<ref>{{cite book |last1=Akagi |first1=Masumi |title=アーケードTVゲームリスト国内•海外編(1971-2005) |trans-title=Arcade TV Game List: Domestic • Overseas Edition (1971-2005) |date=13 October 2006 |publisher=Amusement News Agency |language=ja |location=Japan |isbn=978-4990251215 |pages=13, 42 |url=https://archive.org/details/ArcadeGameList1971-2005/page/n14}}</ref>
