I need to determine the best imaging method for my book scanning robot. Up to this point I have been thinking of using a standarddigital camera to capture the images. However I realized with the limited battery life and storage capacity of a standard camera, I would have to purchase an additional AC adapter and use a camera capture software program which usually only works with higher end cameras. All in all the cost would be at least $400 but probably closer to $500. It seems reasonable that I could probably get a decent web cam at a lower price that could give me a good enough quality image. Most of the web cams I have looked at have a 1.3 megapixel capability but with software enhancement can take a picture of about five or six megapixels. Would I be able to record a fairly good image of a page so the text is legible?
