It means that it is not a coarse detail sensor, like my apple Quicktake with 320x240 pixels of 8 bit colour.from wikipedia
(I suggest that anyone complaining about Canon sensors go back to that technology)
The Apple QuickTake (codenamed Venus, Mars, Neptune)
Time Magazine profiled QuickTake as ‘the first consumer digital camera’ and ranked it among its ’100 greatest and most influential gadgets from 1923 to the present' list
we've come a long way in 20 years
That is kind of funny, considering that consumer digital cameras had been around for about 4 years prior to the Quicktake being launched.
Dycam Model 1 ?
it was shooting 256 tones of gray only (320x240 later 376x284).
i would not call it a digital consumer camera. it was something for computer geeks.
it was only available in japan for a short time.
some say it actually was never sold. others say not more than a few hundred were produced.
digital backs for film cameras? not really a digital camera.
and the price was not really "consumer" friendly.
