Synchronization of a frame rate to a detected cadence includes receiving a sequence of image frames. Motion data recorded contemporaneously with a capture of the sequence of image frames are also received. At least some of the motion data are converted from time domain data to frequency domain data. A dominant frequency in the frequency domain data is determined. Frames from the sequence of image frames are sampled at a sampling frequency related to the dominant frequency. A new image sequence is created using the sampled frames.

Dynamic synchronization of frame rate to a detected cadence in a time lapse image sequence

A frame rate is synchronized to a detected cadence in order to generate an output image sequence that is substantially stabilized. In an in-camera process, a camera receives motion data of the camera while the camera captures the sequence of image frames. A dominant frequency of motion is determined and the capture frame rate is dynamically adjusted to match the frequency of detected motion so that each image frame is captured when the camera is at approximately the same position along the axis of motion. Alternatively, in a post-processing process, frames of a captured image sequence are selectively sampled at a sampling rate corresponding to the dominant frequency of motion so that each sampled frame corresponds to an image capture that occurred when the camera is at approximately the same position along the axis of motion.
