Re: possibility for -faster- digital ?

+ Im still a little in the dark as to how [digital] cameras record
the image... but the following occurs to me, which perhaps some
of the experts here can comment on.

With my little hp-digital, I see a noteable delay when shooting
in reduced light... I still get the picture, but, for instance at
dusk,
the shutter clicks only after a one or two second delay. So... here
is my inquiry... Ive seen (but do not own) "low-lux" video recorders
which assumedly use something similar in the way of chips or
whatever...
and, I think, since these can record in candlelight or other very
low light situations, and seem to do so at video frame recording
rate, these are apparently recording almost instantaneously, rather
than the 1 or 2 second low light delay I get with my camera...
...so, finally, here is the question... could something similar be
utilized, at reasonable cost, in digital snapshot cameras ?
There may already be "faster" digital single frame cameras...
I havent seen digitals advertised this way.
In fact, maybe some of the low-lux video cams can do single
frame exposures.

Just tossing this out for replies. Thanks to any knowledgeable
in this field. Also excuse if this repeats.. I may have asked the
same some time ago.


Hi.

Very much the same as when video and TV cameras were equipped with very wide
range Zoom lenses, and still cameras were limited to 3X Zooms.

The video Cameras had, and still do have, very much poorer picture qualilty.

It is not really noticeable, when we are looking at the moving images,
because our brains are registering a number of frames, and we are averaging
out the images. So you don't notice the low quality.

If you look at a single frame from one of them, you will be very aware of
that poor quality.

If a still camera were to be made which did combine a number of frames from
that kind of sensor, the image would be much better quality, but that would
take more time to do, so there would still be a delay.
