Move over 48MP cameras, Samsung brings new image sensor with 64MP resolution

Move over 48MP cameras, Samsung brings new image sensor with 64MP resolution

The 48MP GW2 sensor has the same features, and both chips are already sampling to customers, with mass production beginning in the second half of the year. The Samsung ISOCELL Bright GW1 is a 64MP image sensor which is now the highest resolution in the industry while the ISOCELL GM2 pushes 48MP resolution. On the other hand, the new ISOCELL Bright GM2 48 MP sensor is the successor of last year's ISOCELL Bright GM1 48 MP sensor.

This new image sensor for mobile devices offers a higher resolution compared to any other sensor on the market right now.

Since the pixel size is similar, the new 64-megapixel ISOCELL Bright GW1 sensor will be physically bigger in size and will be able to capture more light. It is now the industry's highest resolution mobile image sensor. Tetracell is the technology which enables 4-in-1 pixel binning that merges four pixels into a single pixel which manages the pixel size appropriately in low light conditions.

Samsung has also updated 48Mp ISOCELL Bright GM2 which has now embraced the Tetracell technology for better low-light photos and remosaic algorithm in brighter environment.

Samsung also says that the GW1 supports real-time HDR (high dynamic range) of up to 100-decibels. The dynamic range of a conventional image sensor is around 60dB while that of the human eye is typically around 120dB.

The ISOCELL GW1 will also make use of Dual Conversion Gain (DCG) which in turn will make the sensor optimize its full well capacity (FWC) by collecting light more efficiently in well-lit conditions. While the company sells its sensors to other manufacturers, it might reserve the first 64-megapixel units for its own Galaxy Note 10, which should arrive in August or September this year if past history is any guide.

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.
