Slow drawing paintComponent when scrolling

Question

I have the following problem. I have a inteface a la Dune 2 (main map and on the upper right side a navigation map). It won't be used as a game, but just to imagine the kind of interface I'm developing. Anyway, I have a mainimage which holds the 'real' map. The user can move over the scaled mainimage map, so that on the mainscreen you will see only that part (subimage) of it rendered. Works fine. But somehow when I am using mainimages of >400x400 pixels it gets slow. Really weird. Is there a faster method available or am I doing it the wrong way? Any help would be appreciated. Here some code on how I am doing it right now:
BufferedImage mainimage = new BufferedImage(1000,1000, BufferedImage.TYPE_INT_RGB);
public void paintComponent(Graphics g) {    
super.paintComponent(g);       
Graphics2D g2context = (Graphics2D)g;
BufferedImage subimage = mainimage.getSubimage(getAbsoluteX(), getAbsoluteY(), ovp.getBlocksize(), ovp.getBlocksize());
g2context.drawImage(subimage,0,0, getSize(), getSize(), this);
g2context.dispose();
}

Do you use AutoCAD?
The AutoCAD application, when it exits, may leave the graphics subsystem in a state that has a bad effect on interface animation. The problem can be resolved, at least temporarily, by relaunching AutoCAD.
