Hello! I am on an Education account with a university and attempting to use a Lumens DC170 document camera as a video/camera source in Zoom. The camera has a maximum resolution of 1080p, which it is currently set to. I've also set Zoom to use 1080p in Settings > In Meeting (Advanced) > Group HD video. However, when using the DC170 as the camera for Zoom, the image is significantly reduced in quality, as if compressed -- see attachment, where the number to the left of each line indicates what point font it is. I did read that Zoom will downsample video playback of greater than 1080p resolution but this isn't greater than 1080p, so I'm unsure what's causing the issue.
Any thoughts or assistance would be greatly appreciated!

There's a big difference between how Zoom handles participant video and how it handles Screen Share video. For any account that has not been cleared for HD or Full HD, the participant videos will always be distributed no larger than 640x360 to conserve bandwidth. If you are selecting the document camera as your video image, that's what's happening. I'm guessing you're probably Spotlighting your video, or people are Pinning your video, to see it "full screen" and expecting it to come across as 1280x720 (HD) or 1920x1080 (Full HD).
What I recommend is to share your document camera using Screen Sharing. Here's how:
Here's the real secret to why this works: Zoom ALWAYS distributes Screen Share content in the native resolution that it receives it! I once facilitated a webinar where one of the presenters had a 4K monitor... and the received display was always in 4K. Some people complained of bandwidth issues at that point -- those that were on slower networks.
When you're testing this out, bring up the Zoom Settings window and select the Statistics tab on the left. The Screen Sharing sub-tab at top will show you the resolution and frames-per-second being sent or received via screen sharing. The Video sub-tab at top will show you the resolution that you are sending your video to the Zoom servers, and the resolution that ALL participant video is being received by you.
Note that there is a process to request that HD video be made available to your account -- but this only affects the participant camera video, and only under certain conditions. Pursuing Full HD is possible, but not granted to the average account.
Hopefully that's helpful!
