Editing Still video camera (section)

===Development and prototyping===
Canon began developing a still video system as early as 1977 following a secret presentation from [[Texas Instruments]] (TI). Processing the image data from a CCD sensor into a digital file would have required a supercomputer at the time, so a strategic decision was made to use analog recording methods, and Canon recruited Sony and other manufacturers to create a standard format, resulting in the Video Floppy.<ref name=WI-77>{{cite interview |url=https://dc.watch.impress.co.jp/docs/column/165/1221882.html |title=第4回：瀧島芳之さん（元キヤノン取締役、元カメラ事業本部長、元ソフト統括-開発本部長） |trans-title=Number 4: Mr. Yoshiyuki Takishima (former Canon director, camera business division manager, software development general manager) |lang=ja |subject=Yoshiyuki Takishima |interviewer=Yasunori Ichikawa <!--|author=Keiki Toyoda--> |date=December 9, 2019 |publisher=Watch Impress |access-date=10 November 2021}}</ref> Other members included JVC, Matsushita (Panasonic), Olympus, Philips, and RCA.<ref name=PP-8310>{{cite magazine |url=https://books.google.com/books?id=fumEWqHyJqQC&pg=PA10 |title=The Gadgeteria |author=Frank, Michele A. |date=October 1983 |magazine=Popular Photography |pages=10;150 |issn=0032-4582 |volume=90 |number=10 |publisher=Ziff-Davis |location=Los Angeles |access-date=9 November 2021}}</ref>

The first still video camera was a prototype Mavica (a portmanteau of ''ma''gnetic ''vi''deo ''ca''mera), which was unveiled by Sony chair [[Akio Morita]] on August 24, 1981.<ref name=PP-8111>{{cite magazine |url=https://books.google.com/books?id=xFlUkKWm46wC&pg=PA130 |title=How will Sony's video camera affect photography? |author=Drukker, Leendert |date=November 1981 |magazine=Popular Photography |pages=130–131;198;204 |issn=0032-4582 |volume=88 |number=11 |publisher=Ziff-Davis |location=Los Angeles |access-date=9 November 2021}}</ref> The prototype Mavica was equipped with an interchangeable lens and was approximately the size and weight of a conventional 35mm SLR camera at {{cvt|5+1/8|×|3+1/2|×|2+1/16|in}} and {{cvt|28|oz}}. It offered shutter speeds ranging from {{frac|60}} to {{frac|2000}} sec; the video floppy (branded "Mavipak" by Sony) was capable of storing up to 50 images.<ref name=PP-8111/>{{rp|130}} The Mavica was equipped with a single [[Charge-coupled device|CCD]] sensor with a basic resolution of 570×490, but resolution was limited to approximately 350 horizontal lines. This was because it was designed for video playback, which is composed of interlaced [[Field (video)|video fields]] of approximately 240–280 horizontal lines; the Mavica's resolution was slightly boosted by recording color information on a separate FM channel, instead of as a subcarrier to the analog signal.<ref name=PP-8111/>{{rp|131}} At the time, Sony stated it would be 15 to 24 months before the Mavica would be marketed, at an estimated cost of {{US$|660|1981|round=-1}} for the camera and an additional {{US$|220|1981|round=-1}} for the playback unit.<ref>{{cite magazine |url=https://books.google.com/books?id=XBZpIPL1lloC&pg=PA87 |title=Amazing new world of electronic photography |author=Free, John |date=December 1981 |magazine=Popular Science |volume=218 |number=6 |issn=0161-7370 |pages=87–89;124 |publisher=Times Mirror Magazines |location=New York City |access-date=10 November 2021}}</ref>
