South Korean giant Samsung Electronics, today 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.
Delivering an advanced solution, Samsung’s ISOCELL Fast 2L3 is a high speed 3-stack CMOS image sensor designed with the company’s two-gigabit (Gb) LPDDR4 DRAM attached below the analog logic layer. With the integration, the image sensor can temporarily store a larger number of frames taken in high speed quickly onto the sensor’s DRAM layer before sending frames out to the mobile processor and then to the device’s DRAM. This not only allows the sensor to capture a full-frame snapshot at 1/120 of a second but also to 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.
In addition to super slow motion video, fast readout can hugely enhance the photography experience, Samsung said in a press release. Since the sensor captures an image at very high speeds, it significantly reduces the ‘jello-effect,’ or image distortion, when taking a picture of fast-moving objects. By storing multiple frames in the split of a second, the sensor can support 3-Dimensional Noise Reduction (3DNR) for clearer pictures when shooting in low-light, as well as real time high-dynamic-range (HDR) imaging, and detect even the slightest hint of movement for automatic instant slow-motion recording, Samsung said.
According to the South Korean tech titan, the image sensor is also equipped with Dual Pixel technology, which allows each and every one of the 12-million pixels of the image sensor to employ two photodiodes that respectively work as a phase detection auto-focus (PDAF) agent.
The company has said that its ISOCELL Fast 2L3 is currently in mass production.
