Re: Sony QX10 and QX100

Half a year later, did anyone succeed to A. Connect these cameras to a laptop, rather than a smartphone? B. Connect more than one camera at the same time?

Re: Fujitsu ScanSnap SV600

I changed the default settings to 300 dpi, compression level 2, colour only, save as JPEG, and this is what I got, http://runeberg.org/varaung/0001.html Click "Next >>" to see the following pages. Click "full resolution (JPEG)" to see the full 300 dpi image. If you look carefully on some pages, e.g....

Re: HoverCam ImPress Book Scanner

Can 5 megapixels really give good pictures of a printed legal-size magazine page? Their current products all seem to be 3 (T3) or 5 (T5) megapixel cameras.

Re: Ionaudio Booksaver?

Today when I looked, it seems to be on sale again. Can anyone confirm this? Has the design changed?

Re: Platen: Theory And Practice

The second view deals with the "normal view" of the platen. http://www.youtube.com/watch?v=i5iYmLLWCEg Daniel, (sorry for commenting on an old thread) your 80° means the edge of your glass is 10° away from the camera's center, which points perpendicularly towards the center of the glass. If you mov...

Re: Sparkles on DIY Hackerspace Scanner

There is a forbidden zone, where lights should not be because they will cause reflexions. This zone is a rectangular cone that starts at the camera lens and goes to each corner of the glass, where it is mirrored, and forms a bucket shape around the camera. At the camera, this zone is always twice as...

Re: Do we actually need portable cameras ?

Someone mentioned the Logitech C910, which is a $100 webcam that takes 10 megapixel still images. I learned that there is now also a Logitech C920, which at $70 takes 15 megapixel still images. The problem with all webcams, however, is that they have a fixed optical zoom, at quite a wide angle. To g...

Re: Google open-sources a DIY page-turning scanner

I would buy one if it was available, but will not build one myself. I think the design can be improved for easier building and faster scanning. In the prototype, the book spends much time travelling, far away from the image sensors. Compare this to a sheetfed document scanner, where the next page is...
