Samsung Electronics Co., Ltd. introduced the newest addition to its ISOCELL image sensor family, the 3-stack ISOCELL Fast 2L3. The 1.4-micrometer (μm) 12-megapixel (Mp) image sensor with integrated dynamic random access memory (DRAM) delivers fast data readout speeds to capture both rapid movements in super-slow motion and sharper still photographs with less noise and distortion.
 
“Samsung’s ISOCELL image sensors have made great leaps over the generations, with technologies such as ISOCELL for high color fidelity and Dual Pixel for ultra-fast autofocusing, bringing the smartphone camera ever closer to DSLR-grade photography,” said Ben K. Hur, VP of System LSI marketing at Samsung Electronics. “With an added DRAM layer, Samsung’s new 3-stack ISOCELL Fast 2L3 will enable users to create more unique and mesmerizing content.”
 
Conventional image sensors are constructed with two silicon layers; a pixel array layer that converts light information into an electric signal, and an analog logic layer that processes the electric signal into digital code. The digital code is then sent via MIPI interface to the device’s mobile processor for further image tuning before being saved to the device’s DRAM. While all these steps are done instantaneously to implement features like zero-shutter lag, capturing smooth super-slow-motion video requires image readouts at a much higher rate.
 
The sensor can capture a full-frame snapshot at 1/120 of a second and also record super-slow motion video at up to 960 frames per second (fps). With 960fps recording, which is 32 times the typical filming speed (30fps), recording moments such as a child hitting his or her first game-winning homerun, a baby taking his or her first step, or a friend doing a gazelle flip on a skateboard becomes much more dramatic.
 
The Samsung ISOCELL Fast 2L3 is currently in mass production.
