Samsung Electronics has unveiled its latest 200-megapixel (200MP) image sensor, ISOCELL HP2

     Samsung Electronics has launched its latest 200 megapixel (200MP) image sensor, ISOCELL HP2, whose advanced pixel technology and full well capacity will deliver an amazing image experience for future high-end smartphone devices. With a 0.6 micron (μm) size appearance and 1/1.3 inch optical format, it can accommodate 200 megapixels. This is the sensor configuration widely used in high-end smartphones today. And it would be easy for handset makers to go from 108 megapixels to 200 megapixels using optical sensors of the same or similar size in previous models.

     With Tetra2pixel, Samsung's advanced pixel merging technology, the HP2 can simulate different pixel sizes to suit different light levels, allowing the camera to do more work in more scenes. In low-light environments, HP2 converts the sensor into a 1.2 micron (μm) 50 megapixel (50MP) or 2.4 micron (μm) 12.5 megapixel (12.5MP) image sensor by merging four to 16 adjacent pixels.

     Thanks to Samsung's new Dual Vertical Transfer Gate (D-VTG) technology, the HP2 significantly reduces the problem of overexposure in bright light. A voltage transfer gate is placed at the bottom of the photodiode within each pixel to transfer electrons from the pixel to the logical layer. The D-VTG also accurately adds a second transfer gate to the pixel, increasing the pixel's full well capacity by more than 33 percent. By absorbing more electrons and efficiently transmitting signals, this method can reduce overexposure and enhance color reproduction, especially in bright light conditions.

     In low light environments, the Super QPD (Autofocus Solution) allows HP2 to fully invoke 200 million pixels to focus, taking autofocus performance to a new level. In addition, HP2 uses four adjacent pixels to identify horizontal and vertical pattern changes. Even in dim conditions as low as 1 lux, the new HP2 sensor can call on rich pattern data and numerous reference points to quickly autofocus on a subject.

     JoonSeo Yim, executive vice President of Samsung's Sensor business team, said :" To achieve our goal of ultra-high resolution, we designed our sensors not only to add more pixels, but also to continue to advance steadily in the industry through innovative pixel technology. Such as ISOCELL HP2's dual vertical Transfer Gate (D-VTG) technology and dual slope gain (DSG) technology, these sensors can take image quality to new levels. "Going forward, Samsung will continue to push the boundaries of technology and bring exceptional image capture capabilities to mobile devices."
