Canon Patent Reveals Possible New Viewfinder System

A pair of patents published by Canon reveal a viewfinder system for DSLRs that will allow photographers to view their image without ever taking their eye off the viewfinder.
The basic idea behind the patent is that after you take a shot, a small preview of the that image is displayed in the viewfinder, right above the live image. This, in theory, would allow you check your exposure, white balance, composition etc. without taking your eye away from the viewfinder.
The technology behind it, as put by Photography Bay, is "an advanced viewfinder system that uses a small backlit LCD or OLED inside of the finder to project previously captured images onto a mirror in the pentaprism, which in turn, is reflected toward the eye of the photographer. As a result, the photographer sees two images in the viewfinder – the live optical image and the previously-captured image from the LCD."
If you want to learn more about this technology you can read the full publicly available patents at the USPTO website here and here.
Patents can be kinda dry so I suggest reading the Photography Bay article as well that does a good job of breaking it down (they do a great job of screening patents).
Of course, this is just a patent and most of the time they have underlying technology which never manifest into anything more than drawings on a paper. It's an interesting concept none-the-less.
Do you think reviewing your images in the viewfinder would be helpful underwater?

I'm most of the time trying to shoot "new" things. that means, things I never shot before, or things I already shot with new angle, composition, lightning... I think most photographers do that. I think the...
