Samsung's ISOCELL technology has been part of many of its smartphone cameras in recent years. It's a pixel separation technology that helps separate different colored pixels by placing barriers between the different color filters on the sensor, preventing colors from one pixel from affecting the pixels around it and resulting in more color fidelity. Today, Samsung shed some light on its ISOCELL 2.0 technology (via Android Authority), which aims to improve light sensitivity compared to previous generations of ISOCELL.
In its first generation, ISOCELL used metal barriers to separate the different color filters, which prevented colors from bleeding over, but also absorbed a portion of the incoming light, meaning each pixel would be less vivid. This was first improved with ISOCELL Plus, which replaced part of the metal grid with a new, more reflective material. Now, with ISOCELL 2.0, the lower portion of that barrier has also been replaced by this material, making it so that even more light gets through to the sensor, thus producing more vivid colors.
As noted in the video above, this is especially helpful for small pixels, which have become more and more prominent as cameras start at resolutions of over 100MP. With each pixel absorbing more light, that means that more detailed images can be created thanks to the higher resolution, while also having more vivid colors for each of the pixels.
ISOCELL 2.0 technology was already mentioned last year when Samsung introduced an array of ISOCELL-based sensors. The company said that it would start adopting ISOCELL 2.0 in sensors in late 2020, as is the case with the ISOCELL GM5.
