Flicker while redrawing an Image (only one)

Question

I've made an RBGFilter for Images and Combined it with a Thread
to make an Image fade from Color to Grayscale.
I use it together with an home made JComponent. It works, but the Image flickers.
I've tried longer sleep periods (I thougt that maybe the filter was to slow) but it still flickered when changing the Image. I tried dubbel buffering, but couldn't get it to change the Image. Anyway, I suppose double buffering wouldn't help much, while it's only one Image to be drawn and it covers the entire Component.
Does anyone have a clue about how to do?? You'll get plenty of Duke Dollars!
(in the fade class)
public void run()
try{
while( !Thread.interrupted() ){
Thread.sleep( 70 );
//Change colors:
Image tmpImage = Toolkit.getDefaultToolkit().createImage(
new FilteredImageSource( colorImage.getSource(), fadeFilter ) );
ImageComponent.setImage( tmpImage ); //Home made component
//test if fading is finished...
catch( InterruptedException ie ){}
(in the home made component)
public void setImage( Image theImage )
this.theImage = theImage;
repaint();
public void paintComponent( Graphics g )
g.drawImage( theImage, 0, 0, this );
}

Create an adjustment layer then clip it to the layer you want to lighten by clicking between the two layers while holding the alt/opt key.
