Thank you very much for your reply.

Here is my current status.
I tried using both camera1394 and cameradc1394 nodes. But still rviz
does not display any images.
When camera1394 was run, rostopic echo /camera1394/image does not
display anything. So I assume there is no way rviz can display any
When cameradc1394 was run, rostopic echo /camera1394/image display data.
But still, as you mentioned, I could not find /camera/image_raw but
instead the topics 
-OriginalImage(sensor_msgs/Image) are there.
rviz gives the following warning for this case.
Discarding message from [/cameraopencv] due to empty frame_id.

Should I calibrate the camera first?
I did the svn update but still something is missing.

Thank you
