On Thursday (May 9), South Korean electronics giant, Samsung Electronics Co, introduced the world’s highest-resolution image sensor, with 64 megapixels for smartphones, to meet the growing demand for mobile devices with better image quality.
Samsung unveiled two new 0.8-micrometer pixel image sensors-the 64-megapixel ISOCELL Bright GW1 and the 48-megapixel ISOCELL Bright GM2, expanding its 0.8-micrometer pixel image sensor lineup, the smallest pixel size currently available in the market.
“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,” Park said.
ISOCELL Bright GW1 is a 64Mp image sensor that features the highest resolution in Samsung’s 0.8μm-pixel image sensor lineup. With pixel-merging Tetracell technology and remosaic algorithm, GW1 can produce bright 16Mp images in low-light environments and highly-detailed 64Mp shots in brighter settings.
The Tetracell technology merges four pixels into one so that users can achieve high quality images in all light conditions. In bright environments, Tetracell uses a re-mosaic algorithm to produce full resolution images.
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.
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.
ISOCELL Bright GM2 is a 48Mp image sensor that also adopts Tetracell technology in low-light environments and a remosaic algorithm in well-lit settings, bringing highly-detailed pictures with natural and vivid colors. GM2, like GW1, adopts DCG as well for added performance and Super PD for fast autofocus.
Samsung ISOCELL Bright GW1 and GM2 are currently sampling and are expected to be in mass production in the second half of this year.
Samsung first announced its ISOCELL technology in 2013, which reduces color-cross talk between pixels by placing a physical barrier, allowing small-sized pixels to achieve higher color fidelity. Based on this technology, Samsung introduced the industry’s first 1.0um-pixel image sensor in 2015 and 0.9-pixel sensor in 2017. In June 2018, Samsung introduced an upgraded pixel isolation technology, the ISOCELL Plus.
Additionally, the world’s biggest smartphone vendor is also said to be developing various sensors for automotive cameras to meet growing demands for self-driving cars.
The image sensor market is expected to grow to a level comparable to the current memory chip market through 2030 in line with advancements in artificial intelligence and 5G technologies.
