An example embodiment may involve capturing a sequence of images, wherein there are 4 or more images in the sequence of images, and wherein each of the sequence of images has an exposure length of 4-100 seconds; applying a sliding window over the sequence of images as downsampled, wherein at least 4 images are encompassed within the sliding window', and wherein for each position of the sliding window the applying involves: (i) aligning a set of images within the sliding window, and (ii) merging the set of images as aligned into a video frame; combining video frames generated by way of the sliding window into a video file; and storing, by the mobile device, the video file in memory of the mobile device.

The present disclosure relates to a low-light autofocus technique. One example embodiment includes a method. The method includes receiving an indication of a low-light condition for a camera system. The method also includes determining an extended exposure time for a low-light autofocus procedure of the camera system. Further, the method includes capturing, by the camera system, an extended frame for the low-light autofocus procedure. The extended frame is captured by die camera system using the determined extended exposure time. In addition, the method includes determining, based on the captured extended frame, an in-focus lens setting for a lens of the camera system.
