DIY Book Scanner

Are the scanner's cameras capable of capturing images at this point? If so, after having mounted the light, do you see a reflection of the light source in the camera's view? Looking at the dimensions and angles of the platen and camera configuration shown in your first video, it looks like the camer...

I'm so pissed right now! I typed up a response comprising multiple pages explaining the formulas and examples of how to use them to calculate light and camera distances based on page sizes and platen angles and when I clicked on 'Preview' to check the formatting this POS website took me to the login...

Dan's original post regarding platen angles here: https://forum.diybookscanner.org/viewtopic.php?f=17&t=1149 For some odd reason the links to the associated videos don't appear to be in that post any longer. Here they are: Part I Part II Part III I can provide the mathematical routines for determini...

The solution to reflections off the platen glass showing up in your scanned images is a well known scanner design issue involving the platen angle and the location of the camera(s) and scanner's light source. To eliminate the reflection off the adjacent platen glass you need to increase the angle be...

One of them I can set to the high resolution mode. The other one I can't.

Press 'FUNC SET' and then set the camera to PROGRAM (P) mode. You should be able to set the image resolution after making that change.

Unfortunately the Canon Elph 160 doesn't support Live View through that connector. It will only output video over the A/V cable connection when the camera is in PLAYBACK mode and not SHOOT mode. I believe that my Canon DSLRs will happily do this though. They actually have mini-HDMI connectors so it ...

There are other folks that post on this site that would know more about what it would take to capture a live preview from a point-and-shoot camera like the Elph 160 and retrieve that image over a USB connection to a PC. I'm guessing it would involve using a PTP protocol extension via CHDK and LibUSB...

Press the 'FUNC' button, not the 'MENU' button on the back of the camera, then you'll see an option to change the image resolution. I had actually had this particular camera set to 'W' which is less than the 'L' 20 megapixel size. I was playing around with this a while back as the 'W' setting's aspe...

Another data point for you, Bill. I have a Canon Elph 160 here and I took a photo of a page from a random paperback here and the resulting 5152x2896 pixel JPG image file was 5.33MB in size. This camera doesn't have CHDK installed so perhaps that has something to do with what you're seeing? elph160.p...

OK, well thanks for trying. You might be able to upload your large images to one of the free image hosting sites out there and post a link here. You have to be wary of compression artifacts though. Some of these sites will allow large image files to be uploaded but they will compress your file to to...
