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?
Apple spends billions on not only the sensor but also tight integration with hardware and image processing. Even if cars use the same sensors (we’re assuming they can survive the cars operating range here), you still need a lot of hardware and integration to get close to what apple has.
Remember that modern phones with some of the most power efficient processors still overheat when recording 4k in the sun, so imagine that processor but less efficient inside a car and think about what happens then.
