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...

CR2V seems to have been replaced by a Windows application called "VectorEye" in 2003.

Re: a small story for my scanner
You're correct. We don't know how much brighter the light is at the lower edge than the upper corners, only that it is brighter. What I wanted to make apparent is that in that image the light is brighter near the bottom of the page and that distinctive circular pattern across the various levels indi...

Put a black piece of paper (or better, a piece of black velvet fabric) over the other side of the platen glass. Photograph the white paper. Next, replace the black paper with ano...
