Samsung ISOCELL JN1 image sensor goes official with Smart-ISO, Double Super PDAF

by Mohit

On June 10, 2021, Samsung launched the 50-megapixel (MP) ISOCELL JN1 as the world’s first 0.64-micrometer (μm)- pixel picture sensor (smallest). This new camera sensor includes the improved ISOCELL 2.0-pixel innovation, Smart-ISO, and Double Super PDAF to catch more striking pictures.

It furnishes ISOCELL 2.0 innovation with added upgrades that improve light affectability by about 16%. In low light conditions, the JN1 utilizes Samsung’s four-to-one pixel binning tech, Tetrapixel that combines four nearby 0.64μm-pixels into one major 1.28μm-pixel to fourfold light affectability for more brilliant 12.5Mp photos.’

Duckhyun Chang, executive vice president of the sensor business at Samsung said – “Samsung’s advanced pixel technologies have once again pushed boundaries with the utmost precision to develop an image sensor with the industry’s smallest pixel size, yet with powerful performance. The new ISOCELL JN1 at 0.64μm will be able to equip tomorrow’s sleekest smartphones with ultra-high resolution mobile photographs.”

Equipped with several advanced technologies in a small 1/2.76-inch optical format, the ISOCELL JN1 is the most versatile image sensor yet from Samsung. Besides, the JN1 is also compatible with existing 1/2.8-inch products that allow the sensor to be used as wide-angle and as front-facing, ultra-wide, or telephoto cameras.

Smartphones equipped with ISOCELL JN1 will allow users to take highly detailed selfies or group pictures in an amazing 50MP resolution as well as high-resolution video at up to 4K and high-zoom ratios. Aside from the features, it can also reduce the camera module’s height by around 10% for phones’ classy back design.

ISOCELL JN1, Samsung’s most versatile image sensor

To enhance the dynamic range, ISOCELL JN1 is equipped with Smart-ISO, which can change the conversion gain according to the illuminance level of the environment.

Smart-ISO uses a low ISO mode in bright settings to preserve highlights and high ISO reading in low-light environments to reduce noise and produce excellent low-light performance.

Using Smart-ISO, JN1 also provides inter-scene HDR in the mixed light setting to obtain the best exposure level derived from two separate readings of low ISO and high ISO, which are required to create the final image.

For faster autofocus, the ISOCELL JN1 integrates an improved Dual Super PD. The previous Super PD technology used specially designed elliptical microlens to perform phase detection on two adjacent pixels.

The phase-detection pixel density of Double Super PD (1/16) is twice that of Super PD (1/32), and similar autofocus performance can be achieved even in environments where illumination levels are reduced by about 60%.

For smooth, crystal-clear video, the image sensor supports recording 4K resolution video at 60 frames per second (fps) or recording Full HD video at 240fps.
