Samsung ISOCELL GN2 50-Megapixel Image Sensor Announced With Staggered HDR, Dual Pixel Pro Technology


Samsung has launched the brand new 50-megapixel ISOCELL GN2 sensor with giant 1.4-micrometer (micron or μm) sized pixels. This sensor succeeds the ISOCELL GN1 sensor seen on many smartphones, and integrates a brand new Twin Pixel Professional expertise. This expertise utilises 100-million phase-detecting photodiodes that understand phases each vertically and horizontally for quicker and extra correct auto-focusing. It additionally helps staggered HDR for higher element and low energy consumption. Samsung says the brand new staggered HDR function has decreased power consumption by as much as 24 %.

The South Korean electronics large says that the ISOCELL GN2 sensor is at present in mass manufacturing and there are not any actual launch plans introduced, or which telephone will combine it first. The brand new ISOCELL GN2 sensor from Samsung has a 50-megapixel picture sensor and comes with Sensible ISO Professional to supply higher ends in low mild circumstances. The 1/1.12-inch ISOCELL GN2 sensor can simulate a bigger 2.8-micron pixel with 4 pixel-binning expertise to soak up extra mild in low-light circumstances. The sensor additionally provides an choice to take footage in 100-megapixel resolutions. The 100-megapixel mode rearranges the color pixels utilizing an clever re-mosaic algorithm, creating three particular person layers of 50-megapixel frames in inexperienced, purple and blue. These frames are then up-scaled and merged to provide a single ultra-high 100-megapixel decision {photograph}.

Twin Pixel Professional expertise on the Samsung ISOCELL GN2 sensor provides correct and quick auto-focusing, Samsung claims, including that it’s the firm’s most superior phase-detection auto-focus answer but. It provides all-direction focusing by splitting the pixels not solely vertically, as with Twin Pixel, but additionally diagonally. Twin Pixel Professional allows improved low-light focusing and monitoring of shifting objects as properly, as each pixel of the sensor works as focusing brokers. Moreover, there’s a new staggered HDR function built-in that makes use of rolling shutters over the identical pixel arrays to seize a number of frames in brief, center, and lengthy exposures. By maximising the dynamic vary, staggered-HDR is ready to provide wealthy element and vivid color in highlights and darkish shadows throughout the scene, the corporate claims. Samsung says staggered HDR is ready to scale back the power consumption of a sensor by as much as 24 % when in comparison with the predecessor’s real-time HDR mode.

Samsung’s new ISOCELL GN2 sensor additionally has Sensible ISO and Sensible ISO Professional assist to raise mild delicate images. As an illustration, in excessive low-light, Sensible ISO Professional rapidly takes and processes a number of frames in excessive ISO, elevating the sunshine sensitivity near one-million ISOs. The GN2 helps full-HD movies at 480 fps or 4K at 120fps.
