Samsungs new phone sensor promises faster and more accurate autofocus – Engadget

, every sensor pixel is split vertically into 2 photodiodes. Every pixel on the sensing unit is utilized for autofocus, increasing AF speeds without impacting sensor efficiency. Samsung’s Dual Pixel Pro sensing units divided the pixels diagonally rather than vertically. Another brand-new function on the GN2 sensing unit is something Samsung calls staggered HDR technology. The GN2 sensing unit is now in production, indicating it’s likely to appear in upcoming Samsung Galaxy smartphones.

Samsung has revealed its latest mobile phone camera sensing unit with a new feature called Dual Pixel Pro that assures faster and more precise autofocus. The 50-megapixel ISOCELL GN2 sensing unit will likely pertain to Samsung’s next-generation Galaxy smartphones and other devices.

With Dual Pixel phase-detect technology, utilized both by Samsung and Canon, every sensing unit pixel is split vertically into two photodiodes. Because they get the light from a little different angles, focus is computed rapidly and straight based on the balanced out. Every pixel on the sensing unit is used for autofocus, boosting AF speeds without impacting sensor efficiency. That varies from routine phase-detect sensing units, which use far fewer AF pixels distributed around the sensor that negatively effect sensor performance.

Samsung’s Dual Pixel Pro sensing units divided the pixels diagonally instead of vertically. By doing so, each pixel can compare the light coming in from leading to bottom, in addition to from left to right as previously. That permits the system to calculate autofocus more rapidly in particular cases, like when you rotate your mobile phone, for instance. (According to a recent patent, Canon would split the pixels into four to achieve the very same thing.)

Another brand-new feature on the GN2 sensor is something Samsung calls staggered HDR technology. If you’re shooting high-contrast scenes like sundowns, it can catch multiple frames in other words, middle and long direct exposures. That means you might need to hold the camera still to record a shot, though it supposedly utilizes 24 percent less energy compared to Samsung’s real-time HDR mode.

The GN2 also utilizes a new function called Smart ISO. That effectively utilizes several ISO settings in a single picture to “develop high vibrant range images with less motion-artifacts,” according to Samsung. In extremely low light, it can rapidly take and process numerous frames in high ISO, enhancing the light level of sensitivity to nearly 1 million ISO while minimizing noise.

Finally, the GN2 can produce 100-megapixel images a smart re-mosaic algorithm, merging three individual 50-megapixel layers in red, green and blue. “These frames are then up-scaled and combined to produce a single ultra-high 100-megapixle resolution picture,” according to Samsung. As previously, it can also combine four pixels into one for improved low-light sensitivity, at the cost of lower resolution.

The GN2 sensing unit is now in production, suggesting it’s most likely to appear in upcoming Samsung Galaxy smart devices. That might be either a future Galaxy Note gadget or Samsung’s next-gen Galaxy phones (the S22?) due out next year.
