Samsung Makes Autofocus Quicker in New Image Sensor


The Isocell GN1 image sensor with 50 megapixels comes with autofocus for phase detection and absorbs light better, Samsung said.

Samsung has released a new, the company said, 50-megapixel image sensor with auto-focus phase detection (PDAF).

The Isocell GN1 comes with 1.2 micrometer-sized pixels, each pixel having two photodiodes that receive light for phase detection from different angles — a process that has been dubbed dual pixel.

This allows for quicker autofocus and image quality, as opposed to a 100-megapixel sensor, according to Samsung.

The new sensor also comes with the company’s Tetracell technology, which combines four pixel signals as one to better absorb light to take shinier pictures in dark environments.

The combination of these two technologies will allow smartphones to take brighter and sharper pictures in a faster autofocus in extreme low-light environment, the South Korean tech giant said.

Isocell GN1 also allows video recording with 8 K resolution at 30 frames per second and comes with image stabilisation and HDR in real time.

Samsung previously said it would invest 133 trillion won by 2030 in its logic chip business, which includes its business with image sensors.

Samsung has also strengthened its relations with Chinese tech giants, having introduced a 108-megapixel image sensor last year with Xiaomi.

The South Korean tech giant currently ranks second in the global image sensor market, dominated by the Japanese giant Sony who supplies sensors for the iPhone lineup of Apple.

Sony unveiled its latest image sensor last week, fitted with artificial processing intelligence. The company then revealed on Tuesday that for enterprise clients to conduct video analytics, Microsoft Azure AI will be embedded to the sensor.
