Re: WTB or Rent DIY Scanner in Southern US

It is a lot easier to buy ebooks than it is to scan them. I do that for books I can buy. But I have a lot of books that are not available as ebooks. If I check on line and can't find them I go ahead and scan them, realizing that if they do become available I am honor bound to buy the ebook. I have h...

Re: WTB or Rent DIY Scanner in Southern US

I don't think renting would be a good option for you. If you have 1000 books to scan it is going to take a significant amount of time to get them all scanned. I have been scanning books for myself for several years and so far I have scanned about 73 books. It takes me about 15 to 20 hours to complet...

Re: digitizing antique magazines

Could you use a piece of glass or plastic to flatten the page you are scanning? It would add a small bit of effort to the scan, but it might be worth the extra effort, because you might not need any extra software to flatten the image. With older books you would need to be careful not to damage the ...

Re: Raspberry PI camera?

Backing up to my reply yesterday. I tried resetting the image quality on my Elph 160 and then snapped a test shot. When I ran it through the OCR I got a much better file than either the low res or the Pi Cam. So I am recommending that people not use the Raspberry PI with a Pi Camera. The image quali...

Re: Raspberry PI camera?

Thanks, I'll have to try that. In that case the Canon may do a better job than the PI Camera. It will certainly be simpler. I have been beating my head against the wall to get some software that would do what I want. I haven't found any available that does what I want it to do. That would be to show...

Re: Raspberry PI camera?

That is a strange! I checked scans from couple of other books I have scanned and the images are all running in about the same size range. The pixel dimensions are also much lower than yours. But they are 180 dpi, the same as yours. Of course the dpi is kind of an awkward thing. dpi represents how ma...

Re: Raspberry PI camera?

I attributed the improvement of the OCR to the fact that the image from the Pi Camera has much better resolution. However the Pi Camera has 8 MPX resolution and the Canon has 20 MPX resolution. So that is backward from what I was thinking. However the image size is the other way around. The Canon im...

Re: Raspberry PI camera?

I didn't post the original files because the files are so large. I would have to run them through Photoshop to compress them down to a size that I can upload to the forum. So the differences might be lost to the compression. I want to emphasize that this book was worse than average. I spent almost 1...

Re: Raspberry PI camera?

Ok, I don't have a full setup using a Pi Camera for scanning, but I have gotten far enough to do some test scans. I had some problems coming up with a mount that (almost) satisfies me. I decided that the main item of interest was not exactly the look of the images, but what the OCR saw in the images...
