Samsung today announced new Samsung S7 ans S7 edge smartphones, before we begin I must tell you that both the device have same camera module.
The Samsung S7 become the world first smart phone to use the Dual Pixel CMOS AF technology after Canon DSLRs, currently Canon 7D Mark II, Canon 1DX Mark II and 80D using the same technology for auto-focusing, while live view shooting
A look back to Canon Dual-pixel CMOS AF Technology
What is actually Dual-pixel AF
Canon was the first company to introduce Dual-Pixel AF technology. Canon Dual-Pixel CMOS AF system is a complete breakthrough in the field of Auto-focusing technology. The Canon 70D announced on Jul 2, 2013 was the first camera that features Dual-Pixel CMOS AF technology.
The Dual-pixel CMOS AF Sensor features two photodiodes distributed to each microlens. As a result, two parallax images are captured at once. With Dual Pixel CMOS AF, the amount of lens drive is calculated from the amount of signal difference (amount of shift) in the AF points. When the signals of two photodiode are in agreement the Focus is achieved.
The Dual Pixel CMOS AF takes very shorter focusing times and gives you exceptional tracking performance and smoother autofocusing during video shooting.
Its no doubt that by reducing pixels the smartphone is now able to give next level of low-light performance and by adding the Dual-pixel CMOS AF the autofousing speed increased dramatically.
Samsung Dual Pixel AF Tech.
As you can see from the picture same as Canon the Samsung S7 and S7 edge camera modules do the same Job as Canon, the two sub-pixel inside senor work together to calculate the lens drive and acquire AF lock on subject.
Does Canon and Samsung Sony silently signed a Deal ?
Since the AF tech Samsung using is a patent technology of Canon See Dual pixel Patents here | here], and Samsung Galaxy S7 and Galaxy S7 edge use Sony IMX260 camera sensor according to sammobile website
But the best part is the camera module will soon spread over different devices, we will soon see affordable devices by having the same module.
Take a look at the videos:
The camera comes with a bright F1.7 lens to take awesome, even in low light. It also supports a Selfie Flash feature via AMOLED display of the phone as a camera flash when taking selfies.
