Samsung Unveils 64-Megapixel Camera Sensor, Updates Existing 48-Megapixel Sensor


With the 64MP ISOCELL Bright GW1, Samsung is using pixel-merging and remosaic algorithms, in order to create bright 16MP images in low light.

The Korean company today introduced two new sensors with 0.8-micrometer (μm) pixel sizes: the 64-megapixel Samsung ISOCELL Bright GW1 and 48-megapixel ISOCELL Bright GM.

Yongin Park, Executive Vice President of Samsung's sensor business, noted that smartphones have "become the main instrument for recording and sharing our everyday moments".

The ultra-slim Isocell Slim 3T2 delivers high resolution images for both front and back cameras, and should provide the imaging backbone for the next wave of slimline smartphones, which need the smallest possible sensors for their punch-hole or notch design. Tetracell enables 4-in-1 pixel binning that merges four pixels into a single pixel to mitigate the pixel size deficit in challenging light situations.

Now that the Pixel 3a and Pixel 3a XL are out, expect Google to make more announcements. However, we're not losing hope because there is the Huawei Mate X .

The dynamic range of a conventional image sensor is around 60dB while that of the human eye is typically around 120dB. This is said to allow the sensor to optimize its full well capacity (FWC) by using collected light more efficiently especially in bright settings.

After that, the most likely suspect for a 64MP sensor is the Samsung Galaxy S11 (or S20, if Samsung decides to follow typical phone naming conventions), which we'd expect to see in February 2020.

On another hand, GM2 is a 48MP sensor that also utilizes Tetracell for low light condition and remosaic algorithm in a bright environment. Much like the 64-megapixel sensor, the new 48-megapixel sensor also gets Super PD for high-performance phase detection auto-focus. The GM2 adopts DCG for added performance and Super PD for fast autofocus just like the GW1.
