Are More Cameras On A Smartphone Really Helpful?

Recently, you can see that a lot of smartphones are coming with multiple cameras on them and it makes one wonder if it really makes sense to put in so many lenses in a phone. It is exciting to notice that the very highly rated Google Pixel 3 has put in only one lens in times when the Honor Magic 2 smartphone comes with six cameras on it. But does it really matter that these phones are coming with so many camera modules?

Take the Huawei Mate 20 Pro, for instance. It has triple back camera which, surprisingly, has not been rated on the DxOMark camera benchmarking website. The reason given was that the DxOMark score for it was higher than the listed scores on the site. After several detailed tech reviews, it was concluded that the Mate 20 Pro, like the P20 Pro, processes the photo after capturing it.

With a conventional camera, taking two photos with two different lenses isn’t all that useful—you’ll just end up with two mediocre captures. But with specialized image processing, the software on which digital cameras run, you can combine the strength of both lenses and image processors. This gives a photograph that’s brighter and sharper than what the camera could have achieved otherwise.

All smartphones use different versions of Sony Exmor sensors in their cameras. The only difference is the aperture or the size of the sensor. What actually determines a good photograph is the software processing that goes behind it. Expensive smartphones such as the Apple iPhones and the Samsung Galaxy Note and S smartphones use expensive sensors to get more detailed photos. However, while both these phones do capture good photos, Google’s superior AI and machine learning algorithms gives it the edge in terms of HDR and colour accuracy.

In a nutshell, it doesn’t really matter how many cameras you put in your smartphone. Nokia’s upcoming Nokia 9 PureView smartphone is tipped to have a five-camera system while the Galaxy A9 Star already possess a quad-camera system. However, none of them will likely be able to perform against the single camera of the Pixel until they have better algorithms.

Upcoming smartphones are going to heavily rely on AI to process photos to get natural captures and will have a mountain to climb if they ever want to dethrone Google from its pedestal.
