Optimized Exposure Temporal Smoothing For Time-Lapse Mode

Abstract:

A processor of a camera for capturing a time-lapse is configured to acquire a first frame of the time-lapse; calculate an exposure setting for a second frame of the time-lapse; and acquire the second frame of the time-lapse using the exposure setting. The exposure setting prevents a flickering effect in the time-lapse. The exposure setting is determined using one or more preview images that are previewed in a time gap between the first frame and the second frame.
