I am just trying to find the optimum camera for the job

firstly, I was about to buy an expensive 12MP camera, but now I am quite sure its overkill, MP is not an important factor (since even my 2MP cellphone camera does the job)

megapixels myth seems to have effect in OCR as well

I wonder if a good image quality 12MP camera will do it better or worse than a 6MP best best image quality. Also I wonder which specific criteria for image quality are most important for OCR (noise, artifacts, bluriness, dark corners):

also, I am trying to make a set of rules to increase OCR rate. For example, if Finereader usually mistakes n with h in a specific document, it should ask us to train it.
