    Abstract: Dual-lens assemblies and cameras including dual lens-assemblies that include a first lens barrel securing a first lens having a first optical axis and a second lens barrel securing a second lens having a second optical axis are disclosed. In one dual-lens assembly, the first optical axis is approximately parallel to and spaced from the second optical axis by a lateral offset, axial lengths of the first lens barrel and the second lens barrel are approximately equal, and the first lens and the second lens are oriented in opposite directions at opposing ends of the first lens barrel and the second lens barrel.

    Abstract: Systems and methods for providing panoramic image and/or video content using spatially selective encoding and/or decoding. Panoramic content may include stitched spherical (360-degree) images and/or VR video. In some implementations, selective encoding functionality may be embodied in a spherical image capture device that may include two lenses configured to capture pairs of hemispherical images. Encoded source images may be decoded and stitched in order to obtain a combined image characterized by a greater field of view as compared to source images. The stitched image may be encoded using a selective encoding methodology including: partitioning a stitched image into multiple portions, determining if a portion is to be re-encoded. If the image portion is to be re-encoded, re-encoding the image portion. If an image portion is not to be re-encoded, copying previously encoded image portion in lieu of encoding.

    Abstract: Systems and methods for utilizing on-camera sensor information to improve video and/or image encoding quality are discussed herein. Specifically, the systems and methods may utilize on-camera sensor information to efficiently determine whether to encode a particular frame within a set of frames as an intra frame. When captured on video, a particular arrangement of a group of pixels within a frame may comprise a visual representation of an object within the frame. When encoding video footage, motion information characterizing motion of an image capturing device over time may be used to predict displacement of an arrangement of group of pixels between frames. These predictions may be used to efficiently determine whether to encode a particular frame as an intra frame.

    Abstract: Systems and methods for providing video content using spatially adaptive video encoding. Panoramic and/or virtual reality content may be viewed by a client device using a viewport with viewing dimension(s) configured smaller than available dimension(s) of the content. Client device may include a portable media device characterized by given energy and/or computational resources. Video content may be encoded using spatially varying encoding. For image playback, portions of panoramic image may be pre-encoded using multiple quality bands. Pre-encoded image portions, matching the viewport, may be provided and reduce computational and/or energy load on the client device during consumption of panoramic content. Quality distribution may include gradual quality transition area allowing for small movements of the viewport without triggering image re-encoding. Larger movements of the viewport may automatically trigger transition to another spatial encoding distribution.

    Abstract: Apparatus and methods for the stitch zone calculation of a generated projection of a spherical image. In one embodiment, a computing device is disclosed which includes logic configured to: obtain a plurality of images; map the plurality of images onto a spherical image; re-orient the spherical image in accordance with a desired stitch line and a desired projection for the desired stitch line; and map the spherical image to the desired projection having the desired stitch line. In a variant, the desired stitch line is mapped onto an optimal stitch zone, the optimal stitch zone characterized as a set of points that defines a single line on the desired projection in which the set of points along the desired projection lie closest to the spherical image in a mean square sense.

    Abstract: Apparatus and methods for providing a rotated spherical viewpoint (RSV). In one or more embodiments, the RSV is implemented using equirectangular projections (ERPs). The RSV methodologies described herein are particularly suitable for panning within virtual reality (VR) or 360° panoramic content as there is minimal, if any, geometric distortions at the edge of a given viewport. Moreover, the RSV methodologies described herein may reduce the bandwidth requirements of, for example, devices operating in a client-server architecture. Additionally, the computation requirements for providing RSV are minimal and can be provided using relatively simple rotation transforms.
