Why not use a standard processor with camera interface?

I don't know of any processors with a camera interface unless you mean
types
like the TI OMAP. This has to be a mass market cheap solution like the
Omnivision stuff. It's just that we need to interface with 10's of
thousands
existing analog cameras...
^^^^^^^^^^^^^^^

Meindert


The AT91SAM9260 and the AP7000 has a digital camera interface
but if you have signifiant volume,then one of the digital camera chips might
work.

Ulf I expected better from you, he specifically says 'existing' analog cameras.
So this is to go into situations to connect to existing cameras. This is not
replacing cameras situations but obviously a device to hang onto existing
installations/units being sold.

How is replacing existing cameras with digital cameras going to help?

The AT76C115 can do VGA 30 fps compression.

Which if he has CCIR analog cameras (normal resolution 768x576 @ 50Hz
interlaced) is going to be of little use. CCIR was mentioned in his first
post.

Need to talk to your local Atmel representative to get NDA signed/info.

These look like standard 'multimedia' phone chips, not video chips.

Questions for Meindert

1/ Is this CCIR mono or RGB?
2/ What compression rate and delay are you looking for?
3/ Is the output to storage or a transmission link?
4/ What sort of compression are you looking for?

You might need to look at people like LogicDevices www.logicdevices.com
or more likely Averlogic www.averlogic.com.
