Samsung introduces smallest 0.64 μm 50MP ISOCELL JN1 camera sensor
Samsung has finally introduced its first 0.64 μm and 50 MP camera sensor ISOCELL JN1, making it the smallest image sensor to be ever produced by the company and it has also begun its mass production which means that mobiles with this camera sensor will soon arrive in the market and it is only the matter of time.
Samsung ISOCELL JN1 is named so because it uses the enhanced ISOCELL 2.0 technology which increases the light sensitivity by 16% and also reduces the issue of cross talking. It will also help in maintaining colour fidelity by which the colours will not leak into the neighbouring pixel thus enhancing the image quality.

Other technologies present in this camera sensor are double PDAF and smart ISO which are mounted on a 1/2.76 inch optical format. It also has Tetrapixel technology which is used to bin 4 pixels at a time into a big 1.28 μm pixel. This results in bright images of 12.5 MP and enables HDR as two images are captured at a single instance. JN1 is able to capture video with up to 4K resolution with a frame rate of 60 fps as well as at 1080p at a frame rate of 240 fps depending on the type of processor the smartphone has been powered by.
The Double Super PD feature will ensure that there is no change in the auto focus level even when the illumination level is 60% less while the Smart ISO feature enables the sensor to change conversion gain according to illumination level. The Smart-ISO is further categorized into Low ISO and High ISO with the former being used for brightly illuminated environments and the latter for settings with low illumination.
Another notable feature in the ISOCELL JN1 is the introduction of micro lens over the pixels that will not only result in greater accuracy but also enhanced auto-focus speed. Also the phase detection focus feature has been improved than before and it will now be known as Double Super PD.
