I hope all of you are doing well.

Aside from hovering a webcam over a page/book and projecting over a screen (or Monitor for that matter), is there any specifically assigned device that is used for the very purpose of scanning a document and producing it on a screen in real-time.

I have never really heard of any, while my parents have suggested now and then about the existence of some 'document cameras' for this purpose.

I may not be able to land at the point accurately, but I'd be glad to receive some ideas on the same.

Teachers typically use a device called a document camera or a visualizer. There are many types and price ranges, but you can find them in a google search.
