Samsung announces the smallest image sensor for phones

Pinterest LinkedIn Tumblr

announced Samsung announced a new image sensor for smartphone cameras that it says has the smallest pixels in the industry.

The ISOCELL JN1 is a 50-megapixel sensor with a relatively small 1/2.76-inch format, which means it has a pixel size of only 0.64µm.

For comparison, Samsung broke records in 2019 with the slightly larger ISOCELL Slim GH1, another 50MP sensor with 0.7µm pixels.

It is known that smaller pixels usually result in worse image quality with higher noise. But Samsung says it’s all about the diversity of the form factor.

The sensor’s smaller size means it can be used in ultra-wide or telephoto camera modules – which are difficult to design when the size is large – or as a way to reduce the height of the primary camera bump.

As with other high-resolution camera sensors, ISOCELL JN1 takes advantage of pixel binning technology that combines multiple pixels into one for higher light sensitivity.

In this case, Samsung says the sensor captures 12.5-megapixel photos with the equivalent of 1.28 µm pixels.

The company is also claiming a 16 percent increase in light sensitivity with its ISOCELL 2.0 technology.

The ISOCELL JN1 sensor can capture more vibrant images with the industry’s smallest 50MP mobile sensor.

Unusually, Samsung held launch event It says the ISOCELL JN1 is currently in mass production, so it’s likely to appear in smartphones before too long.

“Samsung’s advanced pixel technology has once again pushed the boundaries with utmost precision to develop an image sensor with the smallest pixel size in the industry,” Samsung said. But with a strong performance.

He added: The new sensor can provide future smartphones with ultra-high-resolution images. As we lead our commitment to innovation in pixel technologies, we continue to bring a broad range of image sensor offerings to market.

For faster autofocus, ISOCELL JN1 incorporates enhanced Double Super PD technology.

Previous Super PD technology used specially designed small elliptical lenses across two adjacent pixels arranged side by side for phase detection.

Double Super PD has twice the pixel density used for phase detection compared to Super PD. This enables the same autofocus performance even in environments with 60 percent lower light levels.

The image sensor supports 4K video recording at 60 frames per second. Or in Full HD at 240 frames per second.
