    On Thursday, June 10, 2021, Samsung unveiled a new 50-megapixel image sensor called ISOCELL JN1, which with a pixel size of only 0.64 microns, is the smallest pixel size among other Samsung image sensors. The JN1 is inferior to the newly introduced 50-megapixel ISOCELL GN2 sensor, and unlike the GN2 with its large 1.4-micron pixels, the JN1 comes with a smaller model suitable for slim and compact devices such as a selfie camera, even the Ultra-camera, and the Ultravio camera. . ISOCELL JN1 has acceptable features despite its small size.

    before introducing JN1 , The smallest pixel size among Samsung's camera sensors belonged to models such as the 108-megapixel ISOCELL HM2 sensor, the 64-megapixel ISOCELL GW3 sensor, and a little further the 43-megapixel ISOCELL Slim GH1 sensor, and to date the 0.7 micron-sized limit Was not. In the ISOCELL JN1, however, reaching a pixel size of 0.64 microns makes it possible to shrink the entire sensor to 1/2.76 inches, which Samsung calls the smallest 50-megapixel mobile sensor in the industry. To determine the small size of this sensor, it is enough to compare it with another 50 megapixels from Samsung, namely GN2, whose 1.4 micron pixels have increased the overall dimensions of the sensor to a much larger 1/1.12 inch.

    Samsung, JN1 sensor It is called "suitable for any smartphone from mid-range to flagship" and it uses some features specific to modern sensors; These include ISOCELL 2.0 technology, in which cross-talk interference is minimized by insulating the pixels. In this case, by strengthening the intercellular separators, light penetration from one pixel to another is prevented, and while increasing the sensitivity to light, the color accuracy on the paper also increases. Samsung mentions a 16% improvement in light sensitivity in this regard (without mentioning the reference point of comparison).

    Like other high-resolution mobile sensors, the JN1 supports the ability to combine pixels and form a larger software pixel where four adjacent pixels form on top of each other. They give a larger pixel of 1.28 microns, which will be available for shooting at the default resolution of 12.5 megapixels. The sensor also supports instant HDR capture, where two different images are taken at the same time with different exposures and combined to create a quality image.

    The phase-detection autofocus system in this sensor, now called Double Super PD, has been improved and, according to Samsung, it works faster. In Samsung's previous Super PD system, this mode used elliptical micro-lenses on two adjacent pixels, which were placed side by side, using the image phases for focusing. The new Double Super PD system in JN1 doubles the pixel density used for phase detection from 32.1 to 16.1, and Samsung says it will be able to achieve the same autofocus quality in environments with 60% less light.

    JN1 to increase the dynamic range Comes with Smart ISO technology in which the conversion gain ratio changes based on the ambient brightness level, and Low ISO mode for bright environments to show details in highlights and High ISO for low-light environments for better performance and noise reduction. It works.

    The maximum video resolution supported by this sensor is 4K‌ at 60fps and full HD at 240fps, and the absence of 8K indicates that the sensor is lower than the flagships.

    Samsung ISOCELL JN1 is currently in mass production, and although it has not yet been announced when it will be available on a real device, it certainly will not take long to see this sensor.
