Abstract: An image capture device may experience motion while capturing a video. A video clip may be generated from the video. The beginning of the video clip may be identified based on acceleration of the image capture device during capture of the video, while the ending of the video clip may be identified based on speed of the image capture device during capture of the video.

Abstract: Visual content that includes spatial portions is obtained. A determination is made that one of the spatial portions includes a face. Based on the determination, encoding quality parameters for the one of the spatial portions is identified. The encoding quality parameters are obtained by combining a first distortion model related to the obtaining the visual content with a second model that emphasizes the one of the spatial portions The visual content is encoded. The encoding quality parameters are stored, in association with but separate from, the one of the spatial portions. After decoding, the one of the spatial portions are rendered based on the encoding quality parameters. The encoding quality parameters are obtained by combining a first distortion model related to the obtaining the visual content with a second model that emphasizes the one of the spatial portions.

The steps include tracking a position of the UAV with the vision-based navigation system. The steps include controlling rotors of the UAV to prevent deviations in movement from a desired flight path or position of the UAV. The steps include limiting travel or flight of the UAV to a physical region determined by the desired flight path.

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: Systems and methods are disclosed for image signal processing. For example, methods may include receiving a first image from a first image sensor; receiving a second image from a second image sensor; determining an electronic rolling shutter correction mapping for the first image and the second image; determining a parallax correction mapping based on the first image and the second image for stitching the first image and the second image; determining a warp mapping based on the parallax correction mapping and the electronic rolling shutter correction mapping, wherein the warp mapping applies the electronic rolling shutter correction mapping after the parallax correction mapping; applying the warp mapping to image data based on the first image and the second image to obtain a composite image; and storing, displaying, or transmitting an output image that is based on the composite image.

Abstract: In one aspect of the present disclosure, a digital image capturing device (DICD) is described that includes a first integrated sensor-lens assembly (ISLA) defining a first optical axis and facing in a first direction; a second ISLA defining a second optical axis offset from the first optical axis and facing in a second direction generally opposite the first direction (i.e., such that the second ISLA is rotated approximately 180 from the first ISLA); and a bridge member that is positioned between the first and second ISLAs to fixedly secure together the first and second ISLAs. The bridge member is configured as a discrete structure (i.e., as being separate from both the first ISLA and the second ISLA), and defines a longitudinal axis that is generally parallel in relation to the first and second optical axes.

Characteristics of the music may be determined and used to select the types of visual effects that are applied in the video edit. The characteristics of the music may be extracted from MIDI file/metadata track containing MIDI information for the music.

Abstract: A mounting system for an image capture device that includes three pivotably connected arms is disclosed. The first arm includes a first fastener that is lockable and unlockable to allow for connection and disconnection of the image capture device, and a second fastener that is lockable and unlockable to regulate the position of the image capture device relative to the first arm. The mounting system further includes a third fastener that is lockable and unlockable to regulate the relative positioning between the first arm and the second arm, and a fourth fastener that is lockable and unlockable to regulate the relative positioning between the second arm and the third arm. Whereas the first fastener is removable, each of the second, third, and fourth fasteners is captive to (nonremovable from) the mounting system.

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: Lens mode auto-detection includes obtaining predicate lens mode data, obtaining probable lens mode data, obtaining a lens mode score in accordance with the predicate lens mode data and the probable lens mode data, determining whether the lens mode score is greater than a defined lens mode change threshold, and, in response to determining that the lens mode score is greater than the defined lens mode change threshold, outputting lens mode data.

Abstract: An image is processed using a combination of techniques, particularly, in which low frequency information is processed using multiple tone control and high frequency information is processed using local tone mapping. An image is divided into a plurality of blocks including a given block. Low frequency information and high frequency information of the given block are separated. The low frequency information is processed using multiple tone control. The high frequency information is processed using local tone mapping. A processed image is then produced based on the processed low frequency information and based on the processed high frequency information, the processed image corresponding to the image captured using the image sensor. The processed image is then output for storage or display. Processing the low frequency information can include using a gain curve and bilinear interpolation. Processing the high frequency information can include using an edge preservation filter.

Abstract: Target value detection for an unmanned aerial vehicle is described. The unmanned aerial vehicle includes a first transducer that transmits a first ultrasonic signal and receives a first ultrasonic response and a second transducer that transmits a second ultrasonic signal and receives a second ultrasonic response. The second transducer has a wider beam pattern than the first transducer. Determinations are made as to whether either or both of the first or second ultrasonic responses includes a target value within range areas associated with the respective beam patterns of the first and second transducers. A confidence value is generated based on the determinations. The target value is reflected from an object and the confidence value indicates a likelihood of a position of the unmanned aerial vehicle with respect to the object.
