Re: Open software Windows 10 Processing in 2020

I stick a post-it note onto the blank page for the camera auto-focus look at.
Does your camera support focus lock? If it does, you could set the focus once and it would remain set for shots of subsequent pages.

Re: glass platen construction

These will need holes in the glass to attach the hinge making it more expensive because of the holes. The glass door pivot hinge that I linked to in my previous reply doesn't require you to drill holes in the glass to attach the hinge. The metal set screws bear down on a plastic plate that is place...

Re: New project inspired from Hiroshi Yanagisawa's project

Have you seen images produced by Hiroshi's scanner? From the location of the light source in his design it will be visible as a reflection off of the platen glass.

Re: Scanner in a Briefcase

Can go at 900-1500 pages per min (see video) which is almost as fast as many 2 camera scanners and faster than some. Speed depends on skill, type of trigger and size of book.

Re: Would it be possible a video scanner?

This idea has been discussed here over the years. You can search through the forums for 'video' and probably find a half-dozen posts about it. The important point is to ask yourself how much time are you going to save by developing and using this method over the typical dual-camera V-cradle DIY scan...

Re: glass platen construction

Get a glass door pivot hinge and mount it on the side edge (rather than the back edge like in the photo). Glass Door Pivot Hinge Those brackets look similar to a shelf bracket, but most shelf brackets don't have a long slot for the screws into the wooden shelf. They are probably custom made for this...

Re: Removing chromatic aberration

Is your post spam?
