Redmi Note 7 Camera is Fake 48MP????

Xiaomi recently launched its Redmi Note 7 phone in 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 back along with a secondary 5MP camera for portrait shots. If we talk about hardware, Redmi Note 7 packs a Snapdragon 660 chipset under the hood. When we look into Snapdragon 660 features, the chipset supports only up to the 25MP single camera. So, how does Redmi Note 7 sport a 48MP camera? Is it fake? Let us know the truth behind the 48MP sensor and how it works. Redmi Note 7 48MP camera The Redmi Note 7 sports a 48MP primary rear camera. At present, the 48-megapixel camera is offered by Samsung’s GM1 and Sony’s IMX586 sensors. Redmi Note 7 comes with Samsung GM1 sensor. Samsung’s sensor is a 0.8μm-pixel sensor that is actually a 12MP sensor that results in a 48MP image by combining 4 pixels into 1.

So, even if the output image from Redmi Note 7 is 48MP, it is actually from a 12MP sensor. The Samsung ISOCELL Bright GM1 sensor uses four-in-one 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 4 pixels combine information into 1 pixel. In Samsung GM1 sensor, pixel binning takes pixels in a 2×2 grid and combines them into one.

This data collected by 4 adjacent pixels combine into one “super pixel” and this is called pixel binning. However, the resulting image of this 4-in-1 pixel binning has an effective resolution 4x of the resolution of the sensor.
