Samsung unveils new image sensor with upgraded autofocus

Seoul: Samsung Electronics on Tuesday launched a brand new picture sensor boasting an upgraded autofocus answer because the South Korean tech large eyes to increase its presence within the cellular picture sensor market.

The ISOCELL GN2 is Samsung’s first picture sensor to make use of Twin Pixel Professional expertise.

Like its earlier Twin Pixel answer, it adopts two photodiodes inside each pixel, however the newest one splits the pixels not solely vertically but additionally diagonally.

“This diagonal minimize permits the focusing brokers to raised recognise the highest and backside of the body, permitting the sensor to get in focus rapidly even when there are not any sample modifications in a horizontal course,” Samsung stated.

“Low-light focusing and monitoring of transferring objects are improved as nicely, as each pixel of the sensor works as focusing brokers.”

The 1/1.12-inch ISOCELL GN2 has 50 million 1.four micrometer-sized pixels. With the pixel dimension 0.2 micrometer greater than its predecessor, the ISOCELL GN1, it might probably take in extra mild and supply brighter and sharper photos, in response to Samsung.

The brand new picture sensor additionally gives an choice to take photos in 100-megapixel (Mp) resolutions, utilizing a sophisticated re-mosaic algorithm, which creates three particular person layers of 50Mp frames in inexperienced, purple and blue, coupled with an enhanced upscaling answer.

The ISOCELL GN2 is provided with a staggered-high dynamic vary (HDR) function, which expedites picture processing by sending a readout of lengthy, medium and brief exposures of every row of pixels respectively to the cellular processor.

Samsung stated staggered-HDR can cut back the power consumption of a sensor by as much as 24 % in comparison with the predecessor’s real-time HDR mode.

The ISOCELL GN2 can also be outfitted with Good ISO Professional, which makes use of an intra-scene twin conversion acquire (iDCG) answer, and a wide range of superior pixel applied sciences to enhance cellular pictures.

Samsung’s newest 50Mp picture sensor can help full-HD movies at 480 frames-per-second (fps) or 4K at 120fps for enhanced video-shooting on cellular units.
