I'm not so sure that you need the 5 megapixels, and the key factor is more likely to be the configurability of the camera. If you can control its exposure, its color processing, and its resolution, that will be quite helpful in getting the data you want without noise and without the need for lots of extra processing. The other thing to keep in mind is the development tools and debugging tools. Vision systems rarely work the first time, debugging them can be tricky, and you frequently need to debug them when the environment changes. So invest in the ability to see the images and understand what the various processing steps are doing, and you will be far more productive later.

Sounds like a great project.

With this camera you can do all of that, and more! I'm very excited about it because you can also control these variables:
  • Resolution
  • Brightness
  • Rotation
  • ISO (Essentially shutter speed)
  • Sharpness
  • Contrast
  • Saturation
  • Encoding (Currently only JPEG, BMP, GIF, and PNG)
  • Exposure
  • Auto White Balance
  • Image Effects
  • Metering
  • Horizontal/Vertical/Both Mirroring

I'm trying to add more features so that it will have better debugging, etc. like you said. Any suggestions of what I could add, I would be more than happy to hear!
