I truly don’t understand how in 2023 with all the digitalization we have cars with backup cameras from at best a 2015 mid range smartphone. What’s preventing a manufacturer like bmw for an example from putting a high end sony sensor like the one on the iPhone 15 into their camera modules?
A 108 megapixel phone sensor is not actually outputting anything close to a 108 megapixel stream (that would be 12000x9000 resolution, which is higher than 8K). It combines data from 9 different sensors to create 12 megapixel (4000 x 3000) images. One of it’s specialties is low light situations.
The real problem is that it’s not made to stand up to the use case of a car camera, and requires additional processing power to run which may not work with the zero-fault requirements of backup cameras (the reason the systems are almost always on separate inputs/wiring to the screen than the rest of the failure-prone infotainment).
