We saw this before from Sony and now there is a new patent from Nikon that
seems to describe the very same thing: A curved image sensor! The advantages
of such a sensor would be:
You can design more compact lenses
The Sony patent said there is a 1 stop advantage in making such lens designs
No artifacts or image quality deterioration on corners
My guess is that if that patent will ever be implemented ina real products
this will happen on a fixed lens camera.
