Robert, Maybe you already know this, but the strength of the KNFB reader is to take a picture of a document and turn it into text. It was originally designed to be used on smart phones offering an extremely portable reading solution. It is now available in Windows, but the idea was to be able to use the cameras that are built into many laptops and tablets to allow reading of text. Although I have not used it this way, it can apparently perform Optical Character Recognition on PDF documents and other internal files which does not involve using a camera. However, I do not know if the KNFB Reader checks for a camera or not. It seems to me that back near the beginning of this thread, you asked about whether it can read PDF's. Before you buy it to read PDF's that don't contain text, check out the option in JAWS to do that now. If you are on JAWS 18 or JAWS 2018, it is possible that you already have something that will do what you need.
Also, I don't have experience using it with an external camera as some of mentioned here, but the experience has been that there is a resolution limit that will really help OCR. I have heard a number somewhat lower than Josh gave of 8MB, but his number is probably fine. The point is that it is not the case that the higher the resolution the better the results. A point is reached where there is more information provided than is useful. I hope this answers the question you were really trying to get at. Sometimes we go all around the answer and never hit it directly.

I do not have a smart phone. In order to use the KNFB program to just read PDF's on the computer, do I need a camera? Or can it be done internally within the computer? Windows 10.
