Samsung unveils new high-quit photo sensor for smartphones

Samsung Electronics on Tuesday unveiled its latest 200-megapixel image sensor, the Isocell HP2, with dramatically improved resolution and improved image quality for high-end smartphones.

The new image sensor packs 200 million 0.6 micrometer pixels into a 1/1.3-inch optical format, the sensor size widely used in flagship 108MP smartphone cameras, according to Samsung. This allows the latest high-end smartphones to produce higher resolutions while minimizing on-device camera bumps.

"Samsung ISOCELL HP2 leverages Samsung's high-resolution image sensor technologies and cutting-edge craftsmanship to create high-resolution images," said Yim Joon-seo, Executive Vice President of Samsung's Sensor Business Group. great details.

Our leadership comes from innovative pixel technologies that allow our sensors to go far beyond pixel count and size. We will continue to open up new horizons and strengthen our presence in the growing ultra-high resolution sensor market. 

Samsung says the new product facilitates Samsung's latest vertical transmission dual port technology - an industry first - which greatly reduces the washout effect in photos taken in well-lit environments. brilliant light.

In a photodiode inside each pixel, a voltage-transfer gate is placed at the bottom to transport electrons from the pixels to the logic layer. With high precision, D-VTG adds a second transmission port in the pixel, increasing the pixel's ability to perform well by more than 33%, Samsung says.

With more electrons stored and efficient signal transmission, Samsung says, this method can reduce overexposure and improve color reproduction, especially in bright lighting conditions.

The advanced pixel binning technology, Tetra2pixel, has also been applied in the HP2 to give the camera even more versatility as it simulates different pixel sizes to accommodate different light levels, the giants technology said. The company adds that the use of this technology will improve image quality when shooting in low-light environments as well as when recording 8K high-resolution video.

For superior HDR performance, Samsung first introduced the DSG function in 50MP mode, which applies two separate conversion values ​​to the analog signal received at the pixel level.

Additionally, Smart-ISO Pro, an HDR solution that combines different ISO readings from a single exposure, is used to enable the camera to capture 12.5MP and 4K images at 60 fps/ seconds in HDR. The company has begun mass production of the ISOCELL HP2, Samsung said.
