I modified a Barbie digital camera about a year and a half ago to use a pinhole. I was curious to see the effect of direct rays of light on the CCD. The biggest problem I had was in getting an image at all. The optimal pinhole size was too small to allow enough light through to make an image until I enlarged it a few times. The resulting image was very blurred (but I found it interesting anyway). I assume there is a sensor used to control the duration of the exposure, but don't really have a clue about that actually works. If anyone is interested, the images are at http://www.pinhole.com/pinholer/exhibits/GK.html Gregg > As for small area sensors as in the TI offering.
