According to sources of analyst firm IHS China Chief Executive Kevin Wong, the ‘iPhone 6s’ will come with a 12MP camera, though will smaller individual pixels.
Other analysts and rumors also suggest that the iPhone 6s and iPhone 6s Plus will come with a 12MP camera, but this is the first time an analyst has predicted that Apple will reduce the individual pixel size as well.
Apple stuck to an 8MP sensor on the iPhone 6 and iPhone 6 Plus with an 1.5u pixel size. The bigger pixels allow the sensor to perform better in low-light despite coming with a bigger aperture when compared to other Android smartphones.
A smaller pixel size will lead to more noise in images especially in low-light, but Apple can try to offset this by going with a F/2.0 or F/1.9 aperture lens. It can also reduce noise due to the small pixels by going with a better camera sensor and an updated ISP.
It would have been ideal if Apple would have managed to increase the resolution while keeping the individual pixel size intact, but that would lead to a substantial increase in the camera sensor size. Nevertheless, iPhones are known for their camera performance, and Apple will definitely make other upgrades to the camera system that will drastically improve the image quality.[Via Weibo]
