Samsung showed a 50-megapixel photo sensor with fast autofocus

US, WASHINGTON (ORDO NEWS) — Samsung introduced its first image sensor for smartphones, which simultaneously implements two technologies – Dual Pixel and Tetracell. The first provides faster autofocus, the second serves for better shooting in low light.

Resolution ISOCELL GN1 is 50 megapixels, pixel size – 1.2 microns. According to company representatives, the large pixel size gives higher photosensitivity, as well as the autofocus accuracy of “SLR camera level”.

The closest competitor to ISOCELL GN1 is Sony’s new IMX689 sensor, which can be found, for example, in the Oppo Find X2 Pro. Its resolution is 48 megapixels, the pixel size is 1.22 microns.

By default, the new Samsung takes 12.5-megapixel photos with four pixels, which are then combined into one, which allows you to capture and process more light. “Combining four pixel signals into one, Tetracell doubles the pixel size to 2.4 microns and quadruples the photosensitivity to create brighter frames with a resolution of 12.5 megapixels,” the company said. Video ISOCELL GN1 writes up to 8K at speeds up to 30 frames per second.

The new sensor went into serial production earlier this month. Soon it will be available on Samsung smartphones and new products from other companies.

Support for dual pixel technology Dual Pixel should help Samsung recover from a failure with the Galaxy S20 Ultra. After the release, it turned out that the autofocus operation of its 108-megapixel sensor without Dual Pixel leaves much to be desired. The company promised to release a patch that will smooth out the flaw.
