「ColorOS Know How」 Pixel Binning In Oppo Reno 3 Pro Explained

 View:3587    Reply:11 | Posted at 3-4-2020 15:47:35 | Display all floors | Copy
Hello ColorOS SuperFans!

I recently got my hands on the Oppo Reno 3 Pro. You know what is the first thing I did? Capture some photos. The main camera sensor of the Oppo Reno 3 Pro is 64 MP. But I was surprised when I saw that the photo has the resolution of 16 MP. Upon further investigation, I found that there is a way in the camera app to capture full 64 MP photos. And not only that, we can capture even 108 MP photos. So why Oppo defaulted to 16 MP rather than 64 MP? And what exactly is Pixel Binning in Oppo Reno 3 pro, a technique that is supposed to improve image quality and how does it work?

Camera sensor is made of pixels, which are physical elements on a camera sensor that capture light during photography.

⬇️

We want more and more pixels in our sensor to get high resolution photo.

⬇️

But sensor size is limited to the phone's thickness even with camera bump. A larger sensor usually results in a big camera bump or a thicker phone. This sort of problem doesn’t arise on DSLR because the question of space is not there. In smartphones, there is not enough space to put a big sensor. So this explains the camera bump in most of the smartphones.

⬇️

So, lets keep the sensor the same size and cram all those pixels onto a small sensor. Thus pixel size gets smaller & smaller as we cram more & more megapixels in small sensor.

⬇️

The bigger the pixel size in a camera, the more light it can capture for much sharper and brighter images, which is the goal of every camera manufacturer. Small pixels gather less light than larger pixels.

⬇️

So what's the solution? Here comes the role of Pixel Binning.


Pixel Binning is the process of combining four adjacent pixels into one. So a camera sensor which has a pixel size of 0.9 microns will combine these pixels into a 2×2 grid to form a larger 1.8-micron pixel image. The effective resolution is usually one-fourth of what the sensor is capable of. Combining the pixels will result in a brighter and sharper image, without the hassles of a huge camera sensor. A binned shot on a 64 MP Reno 3 pro camera is thus 16 MP. Thus it explains the great images in low light and continuously improving ultra-dark modes.

If a manufacturer has a phone with a more than 32MP camera, then it's almost guaranteed to have Pixel Binning.

So how Reno 3 pro creates full 64MP photo?
It is explained in the figure below. The quad bayer filter with software based processing produces it. It is slightly better than simply interpolating/upscaling to 64MP.

Here's how to capture 16, 64 and 108 MP photos.

I have compared 16 MP, 64 MP and 108 MP images from Reno 3 Pro below.

Grossly all 3 looks the same when opened fit to screen.

100% zoom to examine the details. 64 MP images has only slight more information than 16 MP image. 108 MP image looks upscaled.

ADVANTAGES

• Resulting image is much brighter when Pixel Binning is used, simply because of the combination of four pixel data into one.
• Lower amounts of noise.
• Slightly better dynamic range and smoother gradation between colours.
• Small file sizes with less storage space required and easy sharing.

DISADVANTAGE


You end up with one-fourth resolution image than the camera sensor is capable of.


CONCLUSION


Pixel binning is one of the most reliable ways to get better photos on your smartphone. This process sees information from four neighbouring pixels combined into one, in order to produce a brighter overall image. Pixel Binning trades sensor resolution for better illumination in an image and truly comes in handy when shooting in low light. While you do lose 1/4th of the sensor resolution, you end up with images that are social media worthy. While it is a remarkable solution to the low light problem, there is still no substitute for a larger sensor with only a higher resolution with no need for binning. Given the space constraints within a smartphone, the use of large format sensors becoming a standard practice is my future dream.
