How Multiple Cameras Work On Android And iOS Smartphones 1

How multiple cameras work on smartphones have always been a question on the minds of most people and 2019 is the year of multiple cameras and many if not all smartphone brands have released phones with multiple cameras. You’ve probably seen the Nokia 9 Pureview with 5 cameras and the Huawei P30 Pro that comes with 4 cameras  (40MP + 20MP +12MP +TOF Camera) and 50x optical zoom.

How Multiple Cameras Work

These two devices come with crazy specifications but I won’t go into that right now, maybe in another post.

However, have you ever tried covering the main camera of your device with a dual camera?

If you haven’t, try doing that right now.

You’ll notice you are actually blocking the whole camera. That leaves the question – What do the secondary cameras do and how do they work.

How Multiple Cameras Work

Now I want you to understand this. Most OEMs have other uses of their secondary camera other than the ones I’m going to mention below. These are just the basic functions of the secondary camera.

The secondary camera improves the overall clarity of the image with the help of a “Monochrome” feature. The secondary camera only records the black and white version of the image. With the help of the Monochrome sensor, the primary camera measures how much light is coming from the point of focus.

Previously (with the exception of the Google Pixel 3), the primary camera in smartphones normally handled the measurement so there was a very high possibility of losing some detail while measuring light intensity since it would still need to work on the color filtering.

So this extra burden is handled by the second camera which takes care of that area. Combining the monochrome image which has detailed information about the light and sharpness with the colored image that was captured by the primary camera will produce a rich and detailed image.

In some phones, the secondary camera acts as the zoom lens. Huawei uses their cameras on the P30 Pro a bit differently but going into the entire details might end up making this post a bit lengthy and a bit boring for people who aren’t hardcore techies so I’d try to keep this balanced. However, if you’d like to see that in another post do let me know in the comments.

So that’s basically how multiple cameras work on smartphones

Tecno Phantom 9 is on its way 3

Tecno Phantom 9 is on its way 4

Just in case you still haven’t heard, Tecno Mobile posted a teaser of their next addition to the phantom series. This was posted on their Facebook page about last week Tuesday.

Tecno Phantom 9 is on its way 5

The phantom series is considered to be Tecno’s top innovations, their flagship lineup. Always incorporated with the best hardware & features from the Chinese company. The phantom 9 seems to be following the same sequence.

From the teaser, we supposedly got a few hints (not sure if this is the right word) of what to expect before it is finally revealed. And it has a couple of impressive specs I’d say.

Here are the following specifications from the teaser;

• 6.4 inch Full view AMOLED display

• Android 9 – the latest android version

• In-display Fingerprint sensor

• 6GB RAM + 128GB ROM

• AI triple camera with dual front flashlight

• 3500mAh battery

I think Tecno needs to be reminded of what a teaser mean, because at this point, you’ll have to wonder how this is a teaser. Permit me to called it a spoiler instead.

What else do they have in store? They literally listed every spec we care about in a smartphone today. Well, only time will tell.

It is still months before Apple unveil their next iPhone, but that has not done enough to avert the ton of leaks online.

The release for the iPhone 11 is set for September this year. Apart from the aesthetics and designs, not much is known about its specifications.

Although there have also been rumors of the iPhone 11 spec sheet, history has severally proven those type of speculations to be unreliable.

Here are the leaked photos. What do you think?
