Sony’s next-generation camera sensor technology is expected to significantly improve the smartphone’s performance when shooting moving objects, as it delivers twice the focus accuracy,media reported. In short, with Sony’s just-released 2×2 OCL on-camera lens solution, image sensors on future mobile devices will be able to capture a new experience of “slapping cats without fear of paste.”

Sony is understood to have unveiled 2×2 OCL mobile camera technology for the first time on December 9, 2019, described below:
The 2×2 OCL is a new technology for high-speed focusing image sensors, with the best Sony Quad Bayer sensors having an on-chip lens on each pixel, while the new scheme is equipped with an on-chip lens on each of the four adjacent pixel groups.
Previously, this scheme has raised some questions about pixel sensitivity. But now, Sony has optimized the structure of the device and introduced a new signal processing technology.
Thanks to this, Sony has greatly improved the focus of smartphone cameras through a 2-by-2 OCL solution.
Up to now, the mobile phone camera multi-phase detection autofocus (PDAF) to separate pixels horizontally, the disadvantage is that it is difficult to deal with the horizontal direction of the lack of pattern changes in the object (such as horizontal edge).
If you keep focusing on the edge of the table, you may encounter some difficulties in actually shooting. If you try to refocus on the table legs, it will be much faster than aiming at the tabletop.
In most cases, this is not a major problem. Because most of the objects we try to shoot are not completely horizontal. But in the near future, the 2×2 OCL solution will free you from this concern altogether.
In addition to horizontal detection, Sony’s 2×2 OCL system is capable of detecting vertically. In each case, phase differences can be used for high-speed autofocus.
Old techniques limit the phase-changing areas that the camera can observe, while the 2-by-2 OCL scheme allows all pixels to be used as imaging pixels and detecting pixels — taking full advantage of the entire sensor space to determine where the focus is placed.
If all goes well, we expect to see a smart machine with a 2×2 on-camera (OCL) camera solution in the second half of 2020.
