Yole Development has published a comparative analysis of the camera technology in the iPhone 6s
and come to the following conclusion:
“The bottom line is that Apple is offering more resolution (MP) but minimal image quality improvement. The company has finally moved on from its previous “big pixel/lower resolution” approach– a move that’s not as radical as it sounds, since Apple still has a 1.22um pixel when everyone else favors 1.12um. This is only a +20% light exposed surface difference (the 1.5um pixel was a +80% difference). The reason for not being able to further their previous approach is lack of space. The iPhone’s thickness (7.1mm) is a major barrier to increasing resolution via the “previous Apple approach” (please refer to this articles first illustration), so Apple must now do what everyone else has been doing for some time: shrink the pixel.”
With a new round of innovation happening now in image sensors, here are some possible directions for next generation Apple cameras:
1.) Hi speed capture (1000 frames/sec or better).
2.) Extended dynamic range with non-Bayer filter sensors and 3D-LUTs(?)
3.) Multi-sensor cameras (a la ‘Light’)
4.) Immersive video via multi-iPhone image sharing.
5.) Apple rolls their own proprietary sensor technology.
