Solution looking for a problem?
Nowadays they compensate for that kind of problem is done through software compensating for the lens distortion with generally good results.
The main problem with a slim camera is the "film" is not as far from the lens.
This means the image is projected onto a smaller area on the film.
To compensate the density of pixels increases and the pixel size decreases.
As pixel size decreases they essentially become more sensitive to light (I'm sure there is a more technical explanation). This sensitivity means higher error ratios causing more noise in the picture.
So until they solve the noise concern this seems pointless.
Sounds like a solution looking for a problem to me.
Now if he really wants a market he could turn it into a coat and include both sensors and emitters then potentially we have an invisibility cloak!
