Hi David,
Happy Holidays to You and Yours as well.
As to magnifying the screen, my first thought is to use software ,either through Windows Settings or 3rd party software.
Win7 does have its own Assistive settings - or Ease Of Access through the Control panel
Magnifier http://windows.microsoft.com/en-US/windows7/Make-items-on-the-screen-appear-bigger-Magnifier
http://windows.microsoft.com/en-US/windows7/introducing-accessibility-in-windows#
ZoomIt
http://technet.microsoft.com/en-us/sysinternals/bb897434
Quite useful ,but items are not clickable ,which is the case for a lot of magnifiers.
Can draw on screen.

Magnifier
http://magnifier.sourceforge.net/ More user settings. Use Graphics Tools setting for providing crosshairs to locate/indicate mouse pointer.
Here's a list of websites that provide Assistive software:

As to using the webcam - You may find the settings in Control panel under Cameras
I'm not sure if in your case it's using Microsoft software or 3rd party, but do a search for camera or cam.
I would not have thought to use a camera to magnify the screen, except for capturing images of external objects like a book.
But in this case ,a rectangular Fresnel lens and good lighting would be an easier solution and not involve a computer.
Plastic (vinyl or acrylic) Freshnel lenses are inexpensive and quite acceptable for reading
Eg http://www.amazon.com/FULL-PAGE-ACRYLIC-MAGNIFYING-FRESNEL/dp/B001N0D81O
Somewhat higher in price http://www.magnifyingchoices.com/store/index.php?main_page=index&cPath=2_86
Hope some of the above will be helpful.

Subject: [PCSOFT] XMAS SOS: USB Camera to Screen?
Happy Holidays All!
My wife's vision is failing. At our local low-vision center, they have
machines with a video camera and a screen for magnifying (and
brightening) things like book pages. For such apparently simple
devices, they're rather expensive....
Her big present today was a new computer with Windows 7 Home Premium
and a 23" monitor, and a USB video camera ("webcam")....
The piece of the puzzle that I think is missing is an application to
put tyhe image from the camera onto the screen. There might be some
utility for this in Win7 that I just don't know about, or I might need
to purchase some third-party application -- but I don't know where to
look or what it might be called...
So: recommendations? advice?
