Xiaomi Redmi Note 7 48 Megapixel

Xiaomi recently launched its Redmi Notation 7 phone in Mainland china. The highlight of the phone is its 48MP camera sensor on the back. The company has used a 48MP Samsung GM1 sensor at the dorsum along with a secondary 5MP camera for portrait shots.

If we talk about hardware, Redmi Notation 7 packs a Snapdragon 660 chipset nether the hood. When we expect into Snapdragon 660 features, the chipset supports only up to the 25MP single photographic camera. So, how does Redmi Note 7 sport a 48MP photographic camera? Is it false? Permit us know the truth behind the 48MP sensor and how it works.

Redmi Annotation 7 48MP camera

The Redmi Annotation 7 sports a 48MP primary rear photographic camera. At nowadays, the 48-megapixel camera is offered by Samsung's GM1 and Sony's IMX586 sensors. Redmi Note 7 comes with Samsung GM1 sensor. Samsung'due south sensor is a 0.8μm-pixel sensor that is actually a 12MP sensor that results in a 48MP image by combining four pixels into ane.

And then, even if the output image from Redmi Annotation 7 is 48MP, it is actually from a 12MP sensor. The Samsung ISOCELL Bright GM1 sensor uses 4-in-i pixel binning technology to make a 12MP image into a 48MP image.

What is Pixel Binning?

The pixel binning is basically an ISP level implementation process where iv pixels combine data into 1 pixel. In Samsung GM1 sensor, pixel binning takes pixels in a 2×2 grid and combines them into one.

So, the information captured by iv private pixels is now combined into ane large pixel that is also called Super Pixel. This data collected by iv adjacent pixels combine into one "super pixel" and this is called pixel binning. Withal, the resulting epitome of this four-in-one pixel binning has an effective resolution 4x of the resolution of the sensor.

Thus by combining raw data from four pixels into i, the output image is of a higher resolution every bit it captured a larger corporeality of low-cal and as well reduced the noise. Xiaomi used this sensor and claims to offering 48MP images that are actually captured from a 12MP sensor. Notwithstanding, the resulting image is brighter and has less noise subsequently using the pixel binning because of the combination of four pixel's data into one.
