Taping to the camera as shown on the left would be challenging to make work at least. The cameras don’t put out light so whatever image you use would have to be on paper thin and light enough for backlighting to work. The distortion that close would also be extreme, so you’d want to keep the main part of your image in the center and small. And yeah, it’d probably be blurry, but the resolution on most of those cameras was already pretty bad up until a few years ago so you might not notice.

It’s not just (or so much) the resolution, it’s what the minimum focus distance of the lens is. I’d bet that is going to be more than a couple of cm
