Cameras are the most coveted items for most when buying a new mobile. It is true that the processing power is important, as well as the RAM, but the vast majority of people have changed their camera for their mobile, so they hope that the replacement has been worth it.
That is why more and more research is being carried out to improve the components responsible for the ability to capture images from a mobile, an effort that continues to bring results.
In this case it is Samsung the one that advertises a new sensor that promises faster and more accurate autofocus. The sensor offers a new feature called Dual Pixel Pro on the 50-megapixel ISOCELL GN2 sensor, which will likely make its way to Samsung’s next-gen Galaxy smartphones and other devices.
Technology to split the pixel
It uses phase detection technology, something used by Canon as well. Each pixel on the sensor is divided vertically into two photodiodes, receiving light from slightly different angles, and that helps focus quickly and directly calculated based on displacement.
The ultimate goal is for you to increase the AF speed without affecting sensor performance. By using more pixels distributed around the sensor, it does not negatively impact the performance of the sensor.
The novelty presented by Samsung
The thing is, Samsung’s Dual Pixel Pro sensors split pixels diagonally rather than vertically. By doing so, each pixel can compare incoming light from top to bottom, as well as left to right as before. That allows the system to calculate the autofocus more quickly than before, even if we rotate the mobile during the capture.
Another new feature of the sensor is something Samsung calls tiered HDR technology. The idea is to be able to shoot high-contrast scenes by capturing short, medium, and long exposures, like normal HDR, but using 24 percent less energy.
The GN2 also uses a new feature called Smart ISO, to use multiple ISO settings in a single photo, reducing noise in photos in extremely low light conditions.
Another new feature is that 100 megapixel images can be produced with an intelligent mosaic algorithm, fusing three individual 50 megapixel layers in red, green and blue.
The GN2 sensor is already in production, which means it is likely to appear on upcoming Samsung Galaxy smartphones. We’ll be alert.
