On February 23, Samsung released the strongest mobile sensor ISOCELL GN2 in a low profile. Its core feature is large. The size of the sensor has soared to 1/1.12 inch. Under the condition of 50 million pixels, the unit pixel is still as high as 1.4 μ m.
The core specification of ISOCELL GN2 is 50 million pixels, 1/1.12 inch, 1.4 μ m unit pixel, which can be 4 in 1 to 2.8 μ m. 4-channel D-PHY (6.5Gbps per channel) and 3-channel C-PHY (3.5Gbps per channel) are used, and the advanced features are not lost:
First launch of Dual Pixel Pro enhanced dual core focusing technology, with a total of 100 million phase focusing points, and diagonal segmentation of green pixels to improve the performance of low light focusing and moving object focusing;
It supports staggered HDR (staggered HDR, using roller shutter on the same array, short, medium and long multi frame exposure, reducing the possibility of overlapping during HDR), and Samsung claims that it can reduce power consumption by up to 24% compared with the previous generation of real-time HDR;
Smart ISO Pro uses in scene dual conversion gain (iDCG) to intelligently adjust the conversion gain of the sensor. The maximum ISO is close to 1 million. It works with staggered HDR to improve dynamic range and color performance;
ISOCELL GN2 supports 100 million pixel mode output, rearranges red, green and blue subpixels through the algorithm, creates three independent 50 million pixel frame layers, and then magnifies and combines them into 100 million pixels;
Support 8K, 4K 120fps and 720P 240fps video recording.
The specification of ISOCELL GN2 is much higher than that of active sensors:
The previous number one is IMX700 (50MP, 1/1.28 '', 1.22 μ m), which is mainly used by Huawei Mate40/P40 series
The second place is Samsung's previous generation GN1 (50MP, 1/1.31 '', 1.2 μ m), mainly the vivo X50 Pro+, X60 Pro+, iQOO 5/5 Pro machines in use;
The third place is OV48C on Xiaomi 10 Ultra (48MP, 1/1.32 ", 1.2 μ m)
Samsung announced that ISOCELL GN2 is in mass production, and it is rumored that Xiaomi 11 Pro/Ultra will be equipped (the bulge of the camera matrix suddenly becomes forgivable. Harmful, this is a camera that can brush MIUI).
The 1/1.12-inch specification is very close to the 1-inch sensor of the card machine, and the excellent multi frame synthesis of the mobile phone has made it possible for the mobile phone to surpass the black card. The biggest cost should be the bulge of the camera brought by the bottom.
