Drawing from the patent literature

This is a very interesting Canon patent. A Canon patent application for a bunch of lenses gives reasons to think Canon is working on curved sensors technology.

Canon patent P2021-43385A (Japan) discusses various optical formulas and optical design for different lens for camera with curved sensors. The patent application was spotted by Hi Lows Note. Learn more about curved sensors here.
