I've hit their web page, and signed up for their developer's program.<br>
|
|
They provide object libraries to access the camera from Wintel, Mac,<br>
|
|
and Mac PPC platforms but offer scant little documentation save for<br>
|
|
instructions on using these libraries.<br>
|
|
<p>
|
|
The most worrisome sign I've noted are referrences to the proprietary<br>
|
|
image compression format used by the dc-20. My guess is that when<br>
|
|
they say propriety they mean that the source code and algorithms are<br>
|
|
not going to be generally available.<br>
|
|
<p>
|
|
I'd expect that I could reverse-engineer the serial protocol used to<br>
|
|
transfer the imagery out of the camera, but if they're transferring<br>
|
|
compressed data using some non-standard compression method comparable<br>
|
|
in complexity to the JPEG compression used by most other cameras, I'm<br>
|
|
afraid that the conversion of the compressed data stream into a usable<br>
|
|
raster image is likely to be more difficult a task than I'm prepared<br>
|
|
to tackle.<br>
|
|

They're cheap, convienent, and offer adequate resolution for many<br>
|
|
tasks. If the need for a Wintel platform in order to get at the data<br>
|
|
could be eliminated, they'd be even better.<br>
