In the quest to build a better smartphone (and justify retail prices of over $1000), Apple is looking to improve the camera on the top-of-the-range iPhone X model for 2018.
The headline news is the schematics show iPhone X Plus will introduce triple rear camera. Huawei beat Apple to market with this technology in the excellent P20 Pro, the iPhone X Plus will be the handset to bring it to the masses.
Apple’s triple lens setup is currently unknown, but it would make sense to copy Huawei’s approach of a monochrome camera aiding the primary and telephoto modules. This produced class-leading low light photography. Low light is also an area where Apple has struggled against rivals (one in particular) over recent years.
