Global shutter might be the most impressive feature, but also notable is that the a9 includes C2PA authentication metadata. This is a cryptographic chain of provenance on digital media, starting at the hardware camera itself.
In addition to provenance itself, C2PA allows for asserting that an image should not be used for AI training / ML mining.

- nayuki 3y agoWhat stops someone from photographing a printed picture of a deepfake?
- pkulak 3y agoNothing, but how do you make that look like a real photo? I want to know how this process survives edits. Is it like HDMI, where I can't watch cable TV on my Linux machines because I don't have some stupid chain of certs from the hardware to my eyeballs? Will I no longer be able to edit my photos on Linux?
