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: 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: Systems and methods are disclosed that capture and compress frames of pixel data. In an implementation, an image sensor chip is configured to convert light into pixel data and generate compressed pixel data at a variable compression rate including applying a transform to pixel data associated with a pixel category from a plurality of pixel categories. The variable compression rate is within an available bandwidth of an output bus configured to output the compressed pixel data.

Abstract: A spherical content capture system captures spherical video and audio content. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest. For each sub-frame, a corresponding portion of an audio track is generated that includes a directional audio signal having a directionality based on the selected sub-frame.

Abstract: An infrared (IR) emitter projects a spherical IR pattern. The IR emitter may include one or more IR lasers to produce two IR laser beams, two beam expanders, two diffraction screens to each produce diffracted radiation, a top wide angle lens, and a bottom wide angle lens. The wide angle lenses may each receive diffracted radiation from a respective one of the diffractions screens and may emit a spherical IR pattern including a plurality of longitudinal lines, each longitudinal line including a first portion of the spherical IR pattern emitted from the top wide angle lens and a second portion of the spherical IR pattern from the bottom wide angle lens. The IR emitter may be part of an object detection system in an aerial vehicle.

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: 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 pair of cameras having an overlapping field of view is aligned based on images captured by image sensors of the pair of cameras. A pixel shift is identified between the images. Based on the identified pixel shift, a calibration is applied to one or both of the pair of cameras. To determine the pixel shift, the camera applies correlation methods including edge matching. Calibrating the pair of cameras may include adjusting a read window on an image sensor. The pixel shift can also be used to determine a time lag, which can be used to synchronize subsequent image captures.
