Samsung's new sensor could see 64 MP smartphone cameras
The company expands its image sensor lineup with 64Mp ISOCELL Bright GW1 and 48Mp ISOCELL Bright GM2 that allow vibrant ultra-high resolution mobile photography
“Over the past few years, mobile phone cameras have become the main instrument for recording and sharing our everyday moments,” said Yongin Park, executive vice president of sensor business at Samsung Electronics. “With more pixels and advanced pixel technologies, Samsung ISOCELL Bright GW1 and GM2 will bring a new level of photography to today’s sleekest mobile devices that will enhance and help change the way we record our daily lives.”
So how will it work ? The ISOCELL Bright GW1 functions as a 16MP sensor in normal usage but it uses what Samsung calls, pixel merging Tetracell technology and remosaic algorithm which can then quadruple the effective pixel area. The GW1 can produce bright 16Mp images in low-light environments and highly-detailed 64Mp shots in brighter settings.
To take pictures resembling the way the human eye perceives its surroundings in a mixed light environment, GW1 supports real-time high dynamic range (HDR) of up to 100-decibels (dB) that provides richer hues. In comparison, the dynamic range of a conventional image sensor is at around 60dB, while that of the human eye is typically considered to be around 120dB.
Sony's IMX586 sensor has the capability to do this in bright conditions but not low light, Samsing Bright GM2 sensor has been released to compete in this line as well.
GW1 is equipped with a Dual Conversion Gain (DCG) that converts the received light into an electric signal according to the illumination of the environment. This allows the sensor to optimize its full well capacity (FWC), utilizing the collected light more efficiently especially in bright environments. Sharper results can be delivered through Super PD, a high-performance phase detection auto-focus technology, and full HD recording at 480 frames-per-second (fps) is supported for smooth cinematic slow motion videos.
Samsung says the are currently sampling ISOCELL Bright GW1 and GM2 sensors and are expected to be in mass production in the second half of this year, so we can probably expect the Galaxy Note 10 and other Samsung flagship devices to have the 64 megapixel sensor this fall.
