Qualcomm's new offering called "Clear Sight" could put dual cameras in more Android phones. It's a single module that's already equipped with two rear cameras and low light imaging algorithms, after all, and phonemakers can simply slap it onto their devices instead of developing their own. It's more similar to Huawei P9's dual cams, co-engineered with Leica, than to the iPhone 7's in that Clear Sight is comprised of a black-and-white and a color image sensor. See, black-and-white sensors can take better images in low-lighting than color sensors can. So, the tech combines the B&W photo taken by one of the cameras with the colors captured by the other to get the best of both worlds.
Since it's only compatible with phones powered by a premium Snapdragon 820 or 821 processor, expect any Clear Sight device to be on the higher end of the pricing scheme. But who knows -- it could make dual cameras so common until they become a staple even in more affordable Android devices.
