The movable sound element can be positioned on the club shaft so as to be selectively retained by the movable sound element assembly and can be configured to release from the movable sound element assembly when the club is swung by the user and as a function of the swing speed thereof. The adjustable grip assembly is axially and rotationally movable so as to dispose the assembly in a plurality of different grip positions.

Abstract: Apparatus and methods for enabling indexing and playback of media content before the end of a content capture. In one aspect, a method for enabling indexing of media data obtained as part of a content capture is disclosed. In one embodiment, the indexing enables playback of the media data during the capture and before cessation thereof. In one variant, the method includes generating an “SOS track” for one or more images. The SOS track does not contain the same information as a full index, but provides sufficient information to allow an index to be subsequently constructed. In one implementation, the provided information includes identifiable markers relating to video data, audio data, or white space, but it does not provide an enumerated or complete “table of contents” as in a traditional index.

Abstract: Apparatus and methods for the pre-processing of image data so as to enhance quality of subsequent encoding and rendering. In one embodiment, a capture device is disclosed that includes a processing apparatus and a non-transitory computer readable apparatus comprising a storage medium have one or more instructions stored thereon. The one or more instructions, when executed by the processing apparatus, are configured to: receive captured image data (such as that sourced from two or more separate image sensors) and pre-process the data to enable stabilization of the corresponding images prior to encoding. In some implementations, the pre-processing includes combination (e.g., stitching) of the captured image data associated with the two or more sensors to facilitates the stabilization. Advantageously, undesirable artifacts such as object “jitter” can be reduced or eliminated. Methods and non-transitory computer readable apparatus are also disclosed.

Abstract: Methods and apparatus for metadata-based cinematography, production effects, shot selection, and/or other content augmentation. Effective cinematography conveys storyline, emotion, excitement, etc. Unfortunately, most amateur filmmakers lack the knowledge and ability to create cinema quality media. Various aspects of the present disclosure are directed to, among other things, rendering media based on instantaneous metadata. Unlike traditional post-processing techniques that rely on human subjectivity, some of the various techniques described herein leverage the camera's actual experiential data to enable cinema-quality post-processing for the general consuming public. Instantaneous metadata-based cinematography and shot selection advisories and architectures are also described.

Abstract: Systems, apparatus, and methods for stabilization and blending of exposures. So-called Electronic Image Stabilization (EIS) techniques use image manipulation software to compensate for camera motion. Unfortunately, existing EIS techniques cannot compensate for artifacts introduced by low shutter speed (e.g., blurs). Various embodiments of the present disclosure generate stabilized images from multiple exposures. In one exemplary embodiment, the stabilized exposures are blended using a linear sum of the color data for each pixel of the image. By stabilizing each exposure and linearly summing the light information, the camera shake can be removed, and the scene motion blur can be controlled. The stabilization and blending techniques enable a mathematical emulation of a selected shutter angle from many high-speed exposures.

Abstract: Methods and apparatus for image processing of spherical content via hardware acceleration components. In one embodiment, an EAC image is subdivided into facets via existing software addressing and written into the memory buffers (normally used for rectilinear cubemaps) in a graphics processing unit (GPU). The EAC facets may be translated, rotated, and/or mirrored so as to align with the expected three-dimensional (3D) coordinate space. The GPU may use existing hardware accelerator logic, parallelization, and/or addressing logic to greatly improve 3D image processing effects (such as a multi-band blend using Gaussian blurs.

Abstract: Methods and apparatus for seamlessly transitioning between lens projections. In one exemplary embodiment, a piecewise lens projection is composed of three (3) functions: (i) a first polynomial-based lens projection, (ii) a second “joining” lens projection, and (iii) a trigonometric lens projection. The piecewise lens projection characterizes virtualized lens distortion as a function of FOV; image data can be dynamically projected based on the virtualized lens distortion, regardless of FOV. In this manner, a user may achieve the visually familiar effects associated with a first lens definition for a first FOV, while still smoothly animating transitions to other lens projections (e.g., a larger FOV using stereographic projections).

Abstract: Video and corresponding metadata is accessed. Events of interest within the video are identified based on the corresponding metadata, and best scenes are identified based on the identified events of interest. A video summary can be generated including one or more of the identified best scenes. The video summary can be generated using a video summary template with slots corresponding to video clips selected from among sets of candidate video clips. Best scenes can also be identified by receiving an indication of an event of interest within video from a user during the capture of the video. Metadata patterns representing activities identified within video clips can be identified within other videos, which can subsequently be associated with the identified activities.

Abstract: Methods and apparatus for shear correction in spherical projections. Embedded devices generally lack the compute and/or memory resources to implement two-dimensional (2D) stitches for spherical projections. Objects (such as a mounting fixture) within a certain distance of the camera may experience a 2D “tear” or “shear” artifact when stitched. Various embodiments of the present disclosure perform two orthogonal 1D stitches: (i) latitudinally across the meridian and (ii) longitudinally along the meridian to approximate the effect of a 2D stitch. Notably, the 1D stitch may be less precise than a true 2D stitch, however the image portion being stitched (e.g., the camera mount) is not the user's subject of interest and can be rendered much more loosely without adverse consequence. Temporal smoothing optimizations are additionally disclosed.
