While dual camera smartphones are becoming commoditized, the first few triple camera harbingers are on the horizon, starting with Huawei’s P20 Pro just launched this week. Challenges and rewards are explained, several configurations are analyzed.

In the past two years we have witnessed mass market adoption of dual camera technologies in most smartphone segments, across almost all manufacturers. We have seen dual cameras adopted both front and back, in various configurations for various end goals. Recent market reports indicate that 30% of smartphones in 2018 will use dual camera technologies, growing to 50% next year. Even though it took the smartphone market more than ten years to add a second camera, it seems that the addition of a third camera is just around the corner, within two years from the adoption of the second camera.

In this White Paper, we will discuss some motivations for adding a third camera to the smartphone imaging complex, the challenges it brings and some possible solutions.
