Hi,
When testing my DFK21 colour camera, with lens cap on (totally dark) have the gain about one quarter way up and exposure @60fps there is a reddish dot top right of frame, but if i make exposures shorter than 1/60th second the dot starts to disappear get up to about 1/80th of a second and it's gone, but as all imaging is under 1/60th then it is always there.

So my question is this a dead, stuck or hot pixel i am seeing?

It's a stuck pixel.

I have 3 on my DBK618.
