It seems to do a fairly decent job. The Viisan has a line showing in the live display image on the computer monitor and you place the book so the line is centered in the crease between pages. Getting that line placed exactly is a bit persnickety and as you can see on one of the first attempt images, if the line is not dead center and the printing is close to the center the image can get cut off a bit by the software algorithm as it does the flattening. As I use the system more, hopefully that placing the book part gets more routine. Even if it doesn't the image check view is fast and taking a new image is just a matter of moving something and hitting the switch again.
The other Mac OS camera I was considering in this range is made by Czur and their software and how to use videos show several lines -- one in the center and then a couple on each side horizontal across the pages. I am not sure if those are laser lines projected on the book or if they are also only on the placement image. Czur claims to have superior and proprietary flattening algorithms. I seriously considered them for a couple of other nice features and reasons but the fact their software for Mac OS 12 and the Apple M1 processor was still in beta with no estimated release date was a deciding factor.
Here is a screen capture of a raw image of the carb info as taken from a laid open book and before it was exported. The image appears nicely flattened and software gives several option of exporting in different formats.
EDIT: This Viisan camera has laser lines which do project on the book and can be turned on independently. Feature is barely mentioned in the operator manual and I found it by accident when seeing a tiny icon in the software and wondering what it did.
