Samsung introduces its own dual camera concept. Could this go in the Note 8?
So, for a while now, we've been hearing that the upcoming Galaxy Note 8 might have a dual camera sensor — a trend that has been entering the mainstream more and more. And while it's not entirely certain that Sammy's top-tier phablet will have the feature, it's quite possible that the company will dabble in the concept in the near future — either with the next Galaxy S flagships or with a special spinoff phone to test audience reaction.
In any case, one question remains — what type of dual camera would it be? Right now, manufacturers do the dual cam thing in three different ways. Apple's iPhones put a telephoto lens on the secondary sensor, providing a 2x optical zoom and more “honest” imaging for portrait shots; LG's solution is to have a super wide angle lens on the secondary camera, allowing the user to get more stuff into the frame; Huawei's method, which is also very popular among lesser-known brands who want to have a dual camera on their phone, is to have one RGB sensor to take photos with and one assistive monochrome sensor to better collect lighting and depth data.
So, if Samsung were to make a dual camera for an upcoming phone, which type would it be?
The ISOCELL Dual concept is shown in a single slide, where we can get some details about it. Much like Huawei's solution, Samsung uses an RGB sensor and a black-and-white sensor that play off of each other. What's a bit of a disappointment is that the example device shown on the board has a lens aperture of F2.0 — definitely smaller than the F1.7 found on last year's Note 7 or this year's Galaxy S8 —, and the sensors' pixels are 1.12 μm small — again, much smaller than the 1.4 μm pixels that are on Sammy's latest and greatest sensors.
So, what does this mean? Smaller pixels usually speak of poor light-collecting capabilities, but one could argue that the monochrome sensor might somehow magically offset this disadvantage. But the smaller aperture would definitely be a step back — it is not only worse at light gathering, it would also introduce a longer depth of field and reduce the phone's natural "bokeh" capabilities, which is something we believe is a generally sought-after effect.
To be exact, we don't believe that this particular concept, which we see at the MWC 2017 Shanghai slide, is the dual camera that would go inside the Galaxy Note 8. It might be a presentation of a dual cam setup, which Samsung would sell to its partners, or one that would go in a lower-tier Galaxy phone. But compared to Sammy's current cameras, what we see here just looks like too much of a downgrade for the sake of having two cameras on one's phone. At least on paper... However, it is quite possible that the Note 8 or the next Galaxy S flagships could use this ISOCELL concept, just with better sensors and lenses.
Time will tell and August is near!
