Death of a CCD: RIP SD110


About a month ago I turned on my Canon SD110 and could see that something was very wrong. This took me by surprise, as I hadn't dropped it, or even taken it anywhere since the last time I took pictures with it, in my living room. I guess it just died of old age after 3 years (and 7000 pictures). The interesting part is that it was clearly the CCD that was failing. In some ways it actually looked pretty neat.

One way you can tell it's the CCD is the streaks in the images. The way data is read from a CCD is by copying off all the pixels along one edge of the CCD, and then shifting all the pixels in the image one pixel toward that edge. The line read off "falls off" the edge, and now the next line of the image can be read in. Part of the trick with CCDs is reading off each line in this way, without causing artifacts by the repeated pixel shifting. Clearly, something is going wrong with that process in my camera.

Wierd. I have the same camera (and same paint issue) and found out today that my CCD has the same problem. I wonder if it's another defect with this model?

Could be - but it's a pretty old camera, so having it fail at this point doesn't necessarily suggest poor design, disappointing though it is.

Too bad I already took mine apart.

In case anybody was wondering, I tried to get Canon to replace the camera, even though I had taken it apart. They were unwilling. Not too surprising, but worth a shot.
