Acquisition of 16-bit USB CCD-Camera using JTwain

[Breukers, C (TNW)]

Hello everybody,

 

After the successful conference in Luxemburg, I have a question about
the acquisition of a 16-bit USB CCD-camera (Meade DSI).

 

Has someone already successfully interfaced this camera in ImageJ? (Now
I use LabVIEW to do this, but if ImageJ can do it this would be very
nice!!!).

 

I downloaded the JTwain plugin and installed it according to the manual,
but I get following message when I try to connect to the camera:

 

PC Camera Device Connect Error

com.asprise.util.jtwain.JTwainException: Failed to acquire imag

 

Does anyone recognizes this error and knows what to do about it?

 

Kind regards,

 

Christian Breukers

Does the camera come with a Twain driver? Does it work with Twain host
applications, such as Photoshop? If it doesn't, you will not be able to
use it with ImageJ using a Twain plugin. Another potential problem is
that, as far as I know, both the JTwain library (used by the JTwain
plugin) and the Gnome library (used by the Twain plugin) only support
8-bit grayscale and 24-bit color.

This is an old post, but for anyone who stumbles upon this topic; I've created a plugin for ImageJ that opens and controls LabVIEW VIs. Anyone facing a similar issue could simply use my plugin to control their camera with LabVIEW and have the images open directly into ImageJ. The plugin is called ImageJVI, it's free, and it's available at www.ImageJVI.org.
