  • Google will fix the main drawback of wide-angle smartphone cameras


    Ultra wide angle lenses allow you to capture more objects in the frame but distort the edges of the picture. This side effect is not too noticeable effect on the appearance of background objects, but significantly changes the facial features of people caught in the frame. You can correct the situation with the help of software filters, but most of them "break" the whole perspective on the photo through retouching. Google engineers managed to find a solution to this problem using a completely new algorithm for the camera smartphone.

    Google's research team has developed a special algorithm with a point perspective adjustment when shooting with wide-angle mobile optics. Unlike existing analogues, this software solution does not "bend" the whole picture, but only affects the selected area. The program independently recognizes faces in the frame and applies a correction to them, keeping the straight lines of the background when shifting faces in the future.

    The work of the algorithm engineers demonstrated in the form of a video — they argue that the technology works fast enough to be "interactive". Presumably, we are talking about adjusting the image on the fly during a video call or in preparation for saving the picture. It is possible that the new feature will debut as part of the firmware Google Pixel 4, the presentation of which is expected in October this year.
