The smaller (and cheaper) the CCD sensor, the worse it's low light performance.
There's not much you can do about that, except to turn on the lights. All those
cheap PC webcams have the same problem. The Lego camera will have the same
problem.
Look at evolution of consumer camcorders - the sensors have the same number of
pixels (or even more), but the physical size has gone from 1/2" to 1/3" and now
1/4" inch. With every generation, picture quality in perfect conditions
(outdoors in bright sunlight) gets better because of improvements in recording
technology, but low light performance gets actually worse because of the
physically smaller CCD sensor.
