hello!

right now i am working on a webcam realtime image processor - that is motion
detection, color recognition, blob tracking etc.

i am working with JMF and a logitech usb cam (the one from the LEGO robotics
system). for the image analysis i would need a stable picture from the
webcam as to the white balance and the automatic gain. the problem: the
camera automatically adjusts itself to new light conditions etc., so that it
is not possible to compare two pictures because of the changing colors!

i happened to find a different program (commercial, windows executable),
that is able to control every single feature of the webcam including
automatic on/off, manual whitebalance, manual gain, etc. - i figured this
has to be possible in java, too.

anyone who knows about a similar project or how to use the JMF or even a JNI
(windows) to control the camera from java??

greetings and thanks in advance -
roland
