REALITY OF 48MP in REDMI NOTE 7 2019

TO Many rumors and queries about the truth behind the camera pixels of Redmi note 7 ..? 

so we have already discussed about its price and features so lets find out the secret behind the highlighted feature of redmi note 7...

Before starting let me clear this smartphone runs on Snapdragon 660 processor which can only hold the capacity to clarify the  object in image that's only 25mp  

The above image shows that snapdragon 660 can make-out 25mp under 160 ISP14-bit Qualcomm spectra.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.

The main effort of this process is of PIXEL BINNING

Pixel binning in simple way it combines 4 pixel to get 1 pixel. In Samsung GM1 sensor, pixel binning takes pixels in a 2×2 grid and combines them into one.

Thus by combining raw data from four pixels into one, the output image is of a higher resolution as it captured a larger amount of light and also reduced the noise. Xiomi used this sensor and claims to offer 48MP images that are actually captured from a 12MP sensor. However, the resulting image is brighter and has less noise after using the pixel binning because of the combination of four pixel’s data into one.
