48 MP cameras are the new trend in the smartphone industry, starting from the Redmi Note 7 Pro to Honor View 20. And there are only two major manufacturers who offer these sensors, Sony and Samsung. Samsung’s ISOCELL GM1 sensor is the only major contender for Sony’s CMOS IMX 586 sensor.
But, the Samsung GM1 sensor is less preferred when compared to Sony’s IMX 586 as Samsung’s sensor actually captures 12MP data and interpolate that through software to get 48MP data. Whereas, IMX586 is able to breakdown the 1.6μm superpixel into a 0.8μm pixel, results in a true 48MP image.
Having said that, Samsung just announced its 64MP sensor which offers amazing possibilities to take mobile photography/videography to a whole new level. Along with this, Samsung also announced a new improved version of the 48MP GM1 sensor.
64 MP Samsung ISOCELL Bright GW1
The 64 MP sensor follows the same path of its elder sibling as it captures16 MP data and through software interpolation, it can attain 64 MP data. Samsung calls this “Tetra cell technology”, which is essentially pixel binning. The new 64MP sensor also supports real-time HDR of up to 100 dB.
The 64 MP sensor is equipped with Dual Conversion Gain (DCG) that converts the received light into an electric signal according to the illumination of the environment. It helps in collecting light more efficiently, especially in bright environments. The new 64 MP sensor also has high-performance phase detection auto-focus technology, which can result in getting sharper images. It also supports full HD recording at 480 fps.
The 64MP sensor is slighly larger when compared to the 48MP sensor, however the pixel size ( 0.8 μm) remains same.
48MP Samsung ISOCELL Bright GM2
This sensor is an upgraded version of the previously launched GM1 sensor which can be seen in smartphones like Redmi Note 7. This new sensor also depends on Tetra cell technology and a remosaic algorithm for both low light and well-lit conditions.
Just like the 64MP GW1 sensor, even this sensor is equipped with a Dual Conversion Gain (DCG) which helps in better performance and faster autofocus.
When can we expect these sensors to hit the market?
Well, Samsung says that these two new sensors are currently in the sampling process and are expected to be in mass production in the second half of this year.
