Sony Mavicaとは 意味・読み方・使い方

Mavica was a brand of Sony cameras which used removable disks as the main recording media. In August, 1981, Sony announced the Sony Mavica (Magnetic Video Camera) electronic still camera, the first commercial electronic still camera. It was not a digital camera, as its CCD sensor produced an analog video signal in the NTSC format at a resolution of 570 × 490 pixels. Mavipak 2.0" diskettes (later adopted industry-wide as the Video Floppy and labelled "VF") were used to write 50 still frames. The pictures were viewed on a television screen. Otherwise, this camera is positioned as the "pioneer of the digital era". The unreleased original MAVICA as well as the later ProMavica MVC-5000 and MVC-7000 were designed as single lens reflex systems with interchangeable lenses. At least the ProMavica MVC-7000 also featured lens mount adapters for Nikon and Canon lenses. The VF format soon evolved into the backward-compatible Hi-VF format, supported by the ProMavica MVC-7000 and the Hi-Band Mavica models.
