If you have a thing for slow motion videos, you’ll like what Samsung will be putting in their phones.
A few days ago, Samsung unveiled the 3-stack ISOCELL Fast 2L3 image sensor. The “3-stack” in the name is what makes a huge difference versus how conventional image sensors are constructed. Image sensors usually only have two silicon layers; a pixel array which takes care of converting light to an electric signal, and an analog logic layer that crunches the electrical signal to digital code. The digital code is then sent to the device’s processor to and saved to the device’s DRAM. AS you can surmise, the complicated process should only take milliseconds.
Samsung’s solution is to put a two-gigabit (Gb) LPDDR4 DRAM below the analog logic layer. This additional layer enables the digital code to temporarily save numerous images before being sent out to the processor and ultimately to the device DRAM. Being able to capture numerous images at a fraction of a second enables jaw-dropping 920fps slo-mo shots. We can now admire how those fidget spinners twirl in its slow motion glory.
For still photography, Samsung claims that devices armed with the new image sensor will be able to take better low-light images as well as real-time HDR (high dynamic range) imaging.
