What is the benefit of applying two Photo-diodes in Samsung Galaxy S7 Edge?

Samsung Galaxy S7 Edge grasps the focus quickly like the human eye by using both the two Photodiodes of each pixel. It’s similar with principle which the eyes work to catch focus. After generating the left-right image and calculating the target position by comparing the distance, lens move to the position at a time. Since it is possible to minimize the lens moving , it’s possible to shoot without shaking at a fast speed focusing.

And since pixel area to receive light is widened due to dual photo-diode and more light lens of F1.7 is applied , it reduces noise and can take a picture with vibrant colors. By a faster shutter speed even in low-light environments, you can shoot high-quality images.
