Abstract: Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.

Abstract: A variable pitch propeller is designed to adjust the pitch of the propeller blade during flight to maximize the propeller efficiency. The propeller blade may comprise airfoil cross-sections. Each cross-section may be composed of different materials at the leading edge and trailing edge. In various embodiments, these materials are selected and oriented to achieve the necessary elastic moduli of the leading and trailing edge for the airfoil cross-section. During liftoff, the airfoil at the blade tip possesses a high blade pitch (e.g. 20 degrees), thereby increasing the generated lift on the propeller blades. During flight or hover conditions when maximal lift is no longer required, the trailing edge of the airfoil displaces upward and reduces the blade pitch to minimize the drag forces on the blade tip.

Abstract: A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.

Abstract: A camera is configured with multiple microphones to reduce wind noise in audio data collected by the camera. The camera receives motion data, which may comprise data indicating acceleration of the camera, a plurality of video frames received by the camera, or a background level of noise associated with one or more microphones configured on the camera. The camera determines a motion vector from the motion data. The motion vector is parallel to the direction of motion of the camera. The camera selects a subset of one or more microphones in the direction of the motion vector. By recording audio data using the one or more selected microphones, the camera reduces wind noise in the audio data.

Abstract: Images captured by multi-camera arrays with overlap regions can be stitched together using image stitching operations. An image stitching operation can be selected for use in stitching images based on a number of factors. An image stitching operation can be selected based on a view window location of a user viewing the images to be stitched together. An image stitching operation can also be selected based on a type, priority, or depth of image features located within an overlap region. Finally, an image stitching operation can be selected based on a likelihood that a particular image stitching operation will produce visible artifacts. Once a stitching operation is selected, the images corresponding to the overlap region can be stitched using the stitching operation, and the stitched image can be stored for subsequent access.

Abstract: An integrated image sensor and lens assembly may include a lens barrel, a collet, and a lens mount. The lens barrel may be coupled to the collet which is coupled to the lens mount. The lens barrel and the collet may each include a fastening structure reciprocal to each other. Alternatively, the collet and the lens mount may each include a fastening structure reciprocal to each other. The optical distance between the set of lenses and the image sensor may be tuned such that the focal plane of the lenses coincides with the image plane. The fastening structures allow the lens barrel to be adjusted relative to the lens mount in order to shift the focal plane in a direction along the optical axis to compensate for focal shifts occurring during assembly/cure and/or temperature cycling.

Abstract: A content visualization system generates visual content for a visualization device based on visual content of an event. The content visualization system collects visual content and source perspective data from visual content sources. The visualization device requests visual content from the content visualization system by providing device perspective data to the content visualization system. The content visualization system generates visual content for the visualization device based on the visual content from the visual content sources, the source perspective data, and the device perspective data. The content visualization system can determine visual content that is relevant to the device perspective by identifying source perspectives that overlap with the device perspective. The content visualization system generates visual content for the visualization device based on the identified visual content. The content visualization system can generate composited or non-composited visual content, based on the similarity of the source perspectives to the device perspective.
