Google Adds Lens Blur to Android Camera App
Google has added new features to the standard Android camera app. Currently available for devices running Android 4.4 Kitkat, Lens blur allows users to mimic shallow DOF and even to virtually "refocus" the photo after it's taken, quasi-Lytro style. "You can choose to make any object come into focus simply by tapping on it in the image," Google's Carlos Hernández writes in a blog post. "By changing the depth-of-field slider, you can simulate different aperture sizes, to achieve bokeh effects ranging from subtle to surreal... Instead of capturing a single photo, you move the camera in an upward sweep to capture a whole series of frames. From these photos, Lens Blur uses computer vision algorithms to create a 3D model of the world, estimating the depth (distance) to every point in the scene." The Google Camera app is available as a free download from the Google Play store.
