Samsung's Galaxy S20 Ultra 108 MP Camera uses "Pixel Binning" technique for low-light photography.
Samsung recently unveiled the Galaxy S20 series and the headliner of the flagships is the Galaxy S20 Ultra. It features a 108MP wide-angle camera, which is an improved version of the sensor previously seen in the Xiaomi Mi Note 10. The South Korean giant has now detailed its 108MP ISOCELL Bright HM1 sensor which features the company’s ‘Nonacell Technology’.
There are many impressive things about the S20 Ultra: the screen, the battery, 5G networking, speed, and more. But the flagship feature is the all-new camera system, which features ultra-high megapixel counts and telephoto zoom in an attempt to kick off the next stage of mobile photography.
In addition to Nonacell Technology, the 108MP ISOCELL Bright HM1 unit also uses Smart-ISO tech to deliver high-resolution images in all kinds of lighting. It’s a 1/1.3-inch sensor with 0.8μm pixels and F/1.8 aperture, which should allow it to capture sufficient amounts of light. However, compared to phones with bigger 1.4μm pixels, noise can potentially be a concern. That’s where Samsung’s new and improved pixel binning technology that it calls Nonacell comes in, which uses a three-by-three array to replicate a 2.4μm pixel to increase light absorption.
At the same time, Samsung has broken through with new, larger sensors that enable dramatically higher pixel counts. Samsung co-developed the 108MP sensor with Xiaomi, which introduced it as part of a five-camera package in a high-end phone late last year.
For even better low-light photography, Samsung is employing a technique called pixel binning, which bundles elements together as one, to pool the light. With the S20 Ultra, Samsung is the first to combine nine pixels into a single light-quenched element. That should result in impressive low-light photos.
What is Pixel Binning?
Pixel binning is a clocking scheme used to combine the charge collected by several adjacent CCD pixels, and is designed to reduce noise and improve the signal-to-noise ratio and frame rate of digital cameras.
Pixel binning is generally made possible thanks to the use of a quad Bayer filter on camera sensors. A Bayer filter is a color filter used in all digital camera sensors, sitting atop the pixels/photo sites and capturing an image with red, green and blue colors.
Samsung is using 9 in 1 Pixel Binning Technique which allows the device to take awesome pictures in low-light conditions.
