Right. Good to hear some improvement is possible. The effect I was 
referring to had more to do with the noise not changing from frame
to frame. Does that mean it's a deterministic effect of the colour 
interpolation, or just the way you detect motion?

Unrelated, do you have any plans to work toward one of the two specified 
colourspaces in the spec?

Right, it obviously doens't work with the colour mosaic sensors. But for 
grayscale being able to trade off resolution for framerate without 
having to reframe the image is a nice feature.
