Samsung Electronics, a pioneer in advanced semiconductor technology has Revealed a new 50 Megapixel camera sensor called ISOCELL GN1 which features faster Autofocus and Brighter Images. The recent Samsung's flagship smartphone Galaxy S20 Ultra was reported to have autofocus issues. This 50 Megapixel camera sensor is Samsung's first sensor to use both dual-pixel autofocus and Tetracell pixel-binning, which the company claims to offer a combination of fast performance and good low-light image quality. \u201cWith innovative pixel technologies, Samsung has been at the forefront of offering high-performance image sensors that closely cater to increasingly diversifying market needs. The ISOCELL GN1 is part of that commitment to deliver stunning images to consumers in any environment,\u201d QUOTED BY YONGIN PARK, EXECUTIVE VICE PRESIDENT OF SENSOR BUSINESS AT SAMSUNG ELECTRONICS The pixel size of 1.2\u03bcm is closer to what you can find on a conventional smartphone phone camera sensor than the high-resolution chips that become increasingly popular over the last year. The direct competitor to this 50MP Camera sensor ISOCELL GN1 will be Sony\u2019s new IMX689 sensor, featured in phones\u00a0like the Oppo Find X2 Pro, which has 48 megapixels at 1.22\u03bcm. This Samsung\u2019s 50 Megapixel Camera sensor will take 12.5-megapixel photos by default with four pixels binned into one. Moreover, this sensor has Dual Pixel technology which creates 100-million phase-detecting photodiodes for snappy auto-focusing and light information that can be translated up to 100 megapixels and Tetracell technology enables light-sensitive 2.4\u03bcm pixels for ultimate low-light photography. ISOCELL\u00a0GN1 50 Megapixel Camera sensor by Samsung Samsung made a bad choice with the Galaxy S20 Ultra by using a 108-megapixel sensor without dual-pixel technology which caused many autofocus issues. We can expect the Note 20 Ultra to have a better camera, altho there are leaks claiming that the note 20 Ultra will also be using the same 108-megapixel sensor from the Galaxy S20 Ultra.
