I just got an eyemodule1 and it seems to be horrible at taking pictures in any lighting I can possibly produce indoors. Anyone else have this problem? The trouble is, white specks appear all over the image in low lighting. In fact, the white specks are in the same place on every picture! (x,y coordinates for each one are the same, and there are hundreds). Just out of curiousity, does the same thing happen for other people? Cover the eyemodule lens with your hand so it should be completely black and take a picture. Does it look like a starfield (mine does!)? Is the starfield exactly the same every time (mine is...)? And does that specific "starfield" appear superimposed over almost any image taken indoors? Attached is what mine looks like...

Thanks,
Mike

Those are called hotpixels, and are the sign of a bad CCD.
Of course, it's an extremely cheap camera, so I wouldn't expect much more.

There is one solution, and that is to use a "dark frame".
Basically take a picture like your sample, and overlay it on every picture you take in Photoshop and subtract the bad pixels.
