Meet Samsung’s 200MP, 8K image sensor for your smartphone

Samsung has released a video showcasing its new 200MP image sensor, which is expected to revolutionize photography and video using your phone.

In the video (below), Minko Kwon, a member of Samsung’s sensor design team, looks at the technology behind the 200MP ISOCELL HP1 transformer sensor. First announced in early September, it promises exceptional image quality and 8K video recording – surpassing even the incredible quality of the Samsung Galaxy S21 Ultra.

Kwon explains how the sensor uses pixel binning to make each 0.64μm pixel “bigger” depending on the mode in use. Pixel clustering combines adjacent pixels to improve signal-to-noise ratio and frame rate, resulting in crisp, clear details. When aggregating pixels in a 4:1 ratio for 8K video, the equivalent pixel size is 1.28μm or 2.56μm when adopting a 16:1 mode, which is used to reduce noise in low light environments.

Samsung’s 200MP sensor lets a phone camera pick up details that the human eye struggles to see, and means you can crop an image while maintaining image quality.

Using a color filter array configured, Samsung designed the sensor so that each of the primary colors covers a 4×4 group of photodiodes – effectively a Bayer pattern. When shooting in high resolution mode, Samsung uses an algorithm called remosaicing, which means that the sensor inserts R, G and B values ​​into these regions.

Based on individual pixel size, the HP1 sensor is expected to be around 10.5 x 8mm or 1/1.22in. That’s large for a smartphone sensor, which typically measures around 6.17 x 4.55mm or 1/2.55in.

Still images and video quality from the ISOCELL HP1 will likely be hard to beat. It supports 8K video at 30 fps, 4K video at 120 fps, and has scaled HDR that will let you shoot images with more dynamic range, while Dual Super PD offers autofocus at Faster and more accurate phase detection with double AF pixel density.

Samsung has yet to announce when the sensor will be widely available, as it’s still being sampled, but according to Sam-Mobile it could be next year – and you can bet the next generation of Android phones will use it as soon as possible.
