==History==
[[File:NHK News Kobe caravan at Aioi J09 168.jpg|thumb|Ikegami high definition video camera of NHK Kobe]]
Ikegami introduced the first portable 4 1/2-inch [[Video_camera_tube#Image_orthicon | Image Orthicon tube]] hand-held TV camera.<ref name="Friendship 7">{{cite web |last1=Ellerbee |first1=Bobby |title=February 20, 1962…Glenn Orbits Earth, CBS Debuts Mini Camera |url=https://eyesofageneration.com/february-20-1962-glenn-orbits-earth-cbs-debuts-mini-camera/ |website=Eyes of a Generation |access-date=6 February 2024 |archive-url=https://web.archive.org/web/20201013180408/https://eyesofageneration.com/february-20-1962-glenn-orbits-earth-cbs-debuts-mini-camera/ |archive-date=13 October 2020 |location=Athens, Georgia |date=20 February 2017 |url-status=live}}</ref> The camera made its debut in the United States in February 1962, when [[CBS]] used it to document the launching of NASA's [[Mercury-Atlas 6|Friendship 7]], its first crewed space mission to orbit the Earth.<ref name="Friendship 7" /> In 1972, Ikegami introduced the HL-33, the first compact hand-held color video camera for [[electronic news gathering]] (ENG). The compact ENG cameras made live shots easier and—when combined with portable videotape recorders—provided an immediate alternative to 16mm television news film, which required processing before it could be broadcast. In addition to ENG, these cameras saw some use in outside broadcasts in Britain, particularly for roaming footage that was not possible to capture using the much larger tradition OB cameras.<ref>Ellis, John; Hall, Nick (2017): ADAPT. figshare. Collection.https://doi.org/10.17637/rh.c.3925603.v1</ref> The later HL-51 was popular among broadcasters for both ENG and [[Electronic field production|EFP]] image acquisition.

Although Ikegami is known as a manufacturer of high-quality television cameras, the company does not make video recorder mechanisms ([[VTR]]s), and was a licensee of professional video formats such as [[Sony]]'s [[Betacam]] SP and [[DVCAM]], and [[Panasonic]]'s [[DVCPRO]]. In 1995, Ikegami co-operated with [[Avid Technology|Avid]] on a tapeless video acquisition format called [[Editcam]], but few were sold. Ikegami developed a tapeless camera format is called GFCAM [[Toshiba]].<ref>{{cite web |url=http://www.ikegami.com/br/products/hdtv/gf_frame1.html |title=Welcome to Ikegami USA Web Page |publisher=Ikegami.com |access-date=2011-03-31 |archive-url=https://web.archive.org/web/20110526155633/http://www.ikegami.com/br/products/hdtv/gf_frame1.html |archive-date=2011-05-26 |url-status=dead }}</ref> 

In the early 1980s, Ikegami developed [[arcade video game]]s as a subcontractor to Japanese video game companies. Among the games they developed are ''[[Computer Othello (video game)|Computer Othello]]'', ''Block Fever'', ''[[Monkey Magic (video game)|Monkey Magic]]'', ''[[Congo Bongo]]'', ''[[Popeye (arcade game)|Popeye]]'', ''[[Donkey Kong (arcade game)|Donkey Kong]]'', ''[[Radar Scope]]'', ''[[Sheriff (arcade game)|Sheriff]]'', ''[[Space Fever]]'', ''[[Space Firebird]]'', ''[[Space Firebird#Legacy|Space Demon]]'', ''[[Heli Fire]]'', ''[[Sky Skipper]]'', ''Space Launcher'', and ''[[Zaxxon]]''.<ref name="autogenerated2005">{{Nihongo|It started from Pong|それは『ポン』から始まった : アーケードTVゲームの成り立ち|sore wa pon kara hajimatta: ākēdo terebi gēmu no naritachi}}, {{Nihongo|Masumi Akagi|赤木真澄|Akagi Masumi}}, {{Nihongo|Amusement Tsūshinsha|アミューズメント通信社|Amyūzumento Tsūshinsha}}, 2005, {{ISBN|4-9902512-0-2}}.</ref> At that time, computer programs were not recognized as copyrightable material. According to these sources, Ikegami proceeded to sue Nintendo for unauthorized duplication of the ''Donkey Kong'' program code for the latter's creation of ''[[Donkey Kong Junior]]'' (1983, Tokyo District Court), but it was not until 1989 that the Tokyo High Court gave a verdict that acknowledged the originality of program code. In 1990, Ikegami and Nintendo reached a settlement, terms of which were never disclosed.<ref>[http://d.hatena.ne.jp/bn2islander/20080817/1218980061 ドンキーコング裁判についてちょこっと考えてみる] {{webarchive|url=https://web.archive.org/web/20100312191324/http://d.hatena.ne.jp/bn2islander/20080817/1218980061 |date=2010-03-12 }} Thinking a bit about Donkey Kong, accessed 2009-02-01</ref>
