Abstract: Images with an optical field of view are captured by an image capture device. An observed trajectory of the image capture device reflects the positions of the image capture device at different moments may be determined. A capture trajectory of the image capture device reflects virtual positions of the image capture device from which video content may be generated. The capture trajectory is determined based on a subsequent portion of the observed trajectory such that a portion of the capture trajectory corresponding to a portion of the observed trajectory is determined based on a subsequent portion of the observed trajectory. Orientations of punch-outs for the images are determined based on the capture trajectory. Video content is generated based on visual content of the images within the punch-outs.

Abstract: Multiple images may be combined to obtain a composite image. Individual images may be obtained with different camera sensors and/or at different time instances. In order to obtain the composite image source images may be aligned in order to produce a seamless stitch. Source images may be characterized by a region of overlap. A disparity measure may be determined for pixels along a border region between the source images. A warp transformation may be determined using a refinement process configured to determine displacement of pixels of the border region based on the disparity. Pixel displacement at a given location may be constrained to direction configured tangential to an epipolar line corresponding to the location. The warp transformation may be propagated to pixels of the image. Spatial and/or temporal smoothing may be applied. In order to obtain refined solution, the warp transformation may be determined at multiple spatial scales.

An observed trajectory of the image capture device reflecting the positions of the image capture device at different moments may be determined. A capture trajectory of the image capture device may be determined based on a subsequent portion of the observed trajectory such that a portion of the capture trajectory corresponding to the one portion of the observed trajectory may be determined based on a subsequent portion of the observed trajectory. Orientations of a capture field of view for the images with respect to the optical field of view of the images may be determined based on the capture trajectory. Video content may be generated based on visual content of the images within the capture field of view.

Abstract: A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. Different field of view punchouts, such as wide field of view punchout and linear field of view punchout, may be used to stabilize the video. Different field of view punchouts may provide different stabilization margins to stabilize the video. The video may be stabilized by switching between different field of view punchouts based on the amount of stabilization margin needed to stabilize the video.

Abstract: An image capture device continuously generates time-lapse video frames to be included within a time-lapse video using a dynamic time-lapse video frame rate, with the value of the dynamic time-lapse video frame rate changing based on activation of a trigger to change the dynamic time-lapse video frame rate. The dynamic time-lapse video frame rate alternates between different values.

Abstract: An image capture device may capture visual content during a capture duration. The context of capture of the visual content by the image capture device may be assessed. The context of capture of the visual content by the image capture device may be used to determine values of stabilization parameters for the visual content.
