Samsung Electronics on Tuesday said it was launching its newest image sensor, Isocell GN2, which has upgraded autofocus features.
The new sensor comes with Dual Pixel Pro technology, which splits some of the pixels diagonally instead of just vertically. Samsung said it was the first to apply this technology.
The diagonal cut allows the focusing agents to better recognize the top and bottom of the frame, allowing the sensor to get in focus quickly even when there are no pattern changes in a horizontal direction, Samsung said.
The technology also allows for greater autofocus on objects or backgrounds with horizontal patterns, the company said.
The 1/1.12-inch Isocell GN2 packs 50 million 1.4 micrometer-sized pixels. The pixels are 0.2 micrometer larger than its predecessor GN1, a Samsung spokesperson said, which increased the surface area that can absorb light by 36%.
The image sensor also comes with Samsung’s Tetracell technology, which groups four pixels into one __ to 12 million pixels __ to absorb light better in low light environments.
It also has a re-mosaic algorithm that can upscale the resolution to 100Mp. For taking pictures in mixed-light environments, such as sunsets or indoors with daylight coming through a window, the GN2 increases its dynamic range with a staggered-HDR feature, a time-multiplexed HDR technology that uses rolling shutters over the same pixel arrays to capture multiple frames in short, middle, and long exposures. Staggered-HDR is also able to reduce the energy consumption of a sensor by up to 24% when compared to the GN1’s real-time HDR mode, as the image data is processed by the sensor before being sent to the application processor.
Isocell GN2 also has a super-slow motion feature that supports filming of Full HD videos at 480 fps or 4K at 120fps.
