Samsung details the cutting edge features of its 200MP ISOCELL HP1 sensor

Samsung continues to push the boundaries of mobile image sensors with its 200 MP ISOCELL HP1 sensor. This sensor is not yet on its way to retailing hardware, but Samsung posted a brief explanation and video of what to expect.

HP1 can act as several different sensors thanks to the deep learning-based remosification algorithm. It can bind 2×2 pixels, resulting in a resolution of 50 MP with an effective pixel size of 1.28 µm. In this mode, it can record 8K video (at 30 fps) with the field of view as small as possible.

Another mode is activated by the sensor’s insane resolution – 4×4 binding, ie 16 sensor pixels are used to create an image pixel. This results in a resolution of 12.5 MP with 2.56 pixelsm pixels, larger than most sensors on the market. The excellent light collection capability is enhanced by smart systems like Smart-ISO Pro, Staggered HDR and more, which we will get to in a second. First, a quick comparison with related sensors.

The 50 MP ISOCELL JN1 was groundbreaking at 0.64 µm pixel size, so there is a family relationship with the HP1. However, the JN1 is small, 1 / 2.76 ”, and the new sensor can match its 50 MP resolution with pixels that are twice as large. The 50 MP ISOCELL GN2 is huge, 1 / 1.12 ”, and its native 1.4 pixelsm pixels can be built into a resolution of 2.8 µm and 12.5 MP, which edges the HP1.

Return to the ISOCELL HP1 features. It supports multisampling, which reads each pixel several times and the average of the measurements. Offset HDR records short, medium and long exposures to increase the dynamic range to 100 dB. Smart ISO works by combining a low and high ISO shot into one. Smart ISO Pro extends this video recording feature, which allows the sensor to record HDR video with fewer motion artifacts.

Finally, to ensure that autofocus is fast and accurate, Samsung equipped the ISOCELL HP1 with Double Super PD. It does what it says at a glance, it’s Super PD with double the number of focus pixels. Focus pixels have microlenses on top of them, which distinguishes them from the other pixels. Note that Double Super PD differs from Dual Pixel autofocus, where each pixel is a focus pixel (GN2 uses Dual Pixel Pro).

When will we see the first phones with HP1? No company has yet announced official announcements, but rumors say that Xiaomi will first have dibs on Samsung’s 200 MP sensor. The company has a solid track record with Samsung’s groundbreaking sensors, such as the first 108 MP sensor (HMX inside the Mi Mix Alpha and Mi CC9 Pro) and the huge 1 / 1.12 ”GN2 (Mi 11 Ultra).
