also, there is something else that must be taken into consideration:

when we are saying that Finereader needs at least a 300dpi scan, or at least a 8MP photo, I think we mean that the fonts must have a minimun size so that the OCR program will recognize them and it will be able to see the differences between the letters

so, a small font text will need more dpi/MP than a large font text

also, we must calculate as image dinemsions, not the dimensions of the paper (A4 or more), but the actual dimensions of the text column (and maybe a little bit bigger just to avoid the blurry corners than most cameras have)

so since 10MP to 12MP is a 10% increase in the font size, and at the same time a significant loss of detail and more noise, I wonder which is the golden section of MP-size sensor-font size
