Canon ION
Canon ION is the marketing name for still video cameras of the Canon RC model series, which was on the market between around 1984 and 1992. These are the first commercially available precursors to today's digital cameras .
The compact still video cameras typically had a 1/2-inch CCD with a resolution of 230,000 to 600,000 pixels, autofocus , automatic exposure with shutter speeds between 1/500 and 1/30 second, a zoom lens with a focal length range of 8 to 24 mm (corresponding to about 43 to 103 mm for small pictures ), delivered a color PAL video signal.
The cameras were delivered together with a digitizer (so-called frame grabber ) for the PC , as there were no standardized graphic formats for digital images at that time; the magnetically stored images had to be digitized for image processing . The cameras cost from 600,000 yen (about 7,500 DM, model RC-760 in 1987) to 100,000 yen (about 1,250 DM, model RC-250 in 1989).
