A first image frame is gathered. The first image frame, a first white balance value, and a first exposure value are stored. Information is sensed from an inertial sensor. A second image frame and intermediate image frames are gathered. A distance traversed by a camera is determined. In response to one or more of: the distance exceeding a predetermined threshold, or a new white balance value significantly differing from a previous white balance value, or a new exposure value significantly differing from a previous exposure value, a second white balance value and a second exposure value are determined for the second image frame. A smoothed white balance value and a smoothed exposure value are determined for the intermediate image frames.

Using inertial sensors to provide smoothed exposure and white balance adjustments for video and photographic applications

Systems and related methods for detecting a scene in video content are provided. In one example, a scene detection program identifies a plurality of shots in the video content and selects a target shot. The program builds a forward window including the target shot and having shots that are temporally ahead of the target shot, and a rearward window having shots that are temporally behind the target shot. For each of the shots in the forward window the program determines a dissimilarity between a selected shot in forward window and each of the other shots in the rearward window. If one or more of the dissimilarities is less than a scene boundary threshold, the program determines that the scene does not begin at the target shot. If none of the dissimilarities is less than the scene boundary threshold, the program determines that the scene begins at the target shot.
