Abstract: Systems, apparatus, and methods adding post-processing motion blur to video and/or frame interpolation with occluded motion. Conventional post-processing techniques relied on the filmmaker to select and stage their shots. Different motion blur techniques were designed to fix certain types of footage. Vector blur is one technique that “smears” pixel information in the direction of movement. Frame interpolation and stacking attempts to create motion blur by stacking interpolated frames together. Each technique has its own set of limitations. Various embodiments use a combination of motion blur techniques in post-processing for better, more realistic outcomes with faster/more efficient rendering times. In some cases, this may enable adaptive quality post-processing that may be performed in mobile/embedded ecosystems. Various embodiments use a combination of video frame interpolation techniques for better interpolated frames with faster/more efficient rendering times.

Abstract: An image capture system for enhanced electronic image stabilization (EIS) includes an image capture device and an adapter lens. The image capture device includes an image sensor, a lens housing, a processor, and a lens assembly that includes a first group of optical elements disposed within the lens housing. The first group of optical elements are used project an image onto the image sensor. The processor performs EIS. The adapter lens is used to enhance EIS of the image capture device. The adapter lens has an adapter lens housing that interfaces with the lens housing. The adapter lens has a second group of optical elements disposed within the adapter lens housing. The second group of optical elements are used to project the image as an image circle on the image sensor.

Abstract: An image capture device may analyze visual content to determine a smile aggregation value. The smile aggregation value satisfying a smile aggregation criterion may indicate that people depicted in the visual content are smiling. When the smile aggregation value satisfies the smile aggregation criterion, the capture of visual content may be started. When the smile aggregation value fails to satisfy the smile aggregation criterion, the capture of visual content may be stopped.

Abstract: A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. Different field of view punchouts, such as wide field of view punchout and linear field of view punchout, may be used to stabilize the video. Different field of view punchouts may provide different stabilization margins to stabilize the video. The video may be stabilized by switching between different field of view punchouts based on the amount of stabilization margin needed to stabilize the video.

Abstract: Multiple punchouts of a video may be presented based on multiple viewing windows. The video may include visual content having a field of view. Multiple viewing windows may be determined for the video, with individual viewing window defining a set of extents of the visual content. Different punchouts of the visual content may be presented based on the different viewing windows. Individual punchout of the visual content may include the set of extents of the visual content defined by corresponding viewing window.

Abstract: Positions of an image capture device during capture of a video may be transferred to a computing device before the video is transferred to the computing device. The positions of the image capture device may be used to determine a viewing window for the video before the video is obtained. The viewing window may be used to present a stabilized view of the video when the video is obtained. For example, a stabilized view of the video may be presented as the video is streamed to the computing device.

Abstract: Systems, apparatus, and methods for “fast” wake-up using virtualized addresses. Action cameras need to conserve power most of the time, but also be immediately responsive to catch action when it happens. Unfortunately, most general-purpose operating systems (e.g., Linux-based) lock up the processor during boot-up. Empirically, an OS boot process might take between 6-7 seconds from start to finish, even in highly streamlined boot sequences. This is undesirable, especially where one device (e.g., a smart phone) triggers an action camera to capture an image. Various embodiments of the present disclosure create “virtual action addresses” that directly expose interrupts as addressable space (via a Bluetooth Low Energy (BLE) network). In one such example, the interrupts trigger a capture or other action. The action camera can immediately service the interrupts with its real-time operating system (RTOS) while the general-purpose OS is booting up.

Abstract: An image capture device with dynamic wind noise compression tuning techniques is described. A technique includes detecting of the presence of wind noise by measuring coherence between at least two microphones. For a compressor, adjusting a default compression threshold and default compression parameters based on the coherence measurements. For each microphone, applying by the compressor the adjusted compression parameters when an audio signal is above the adjusted compression threshold and applying the default compression parameters when the audio signal is below the adjusted compression threshold.

Abstract: Methods and apparatus for blending unknown pixels in overlapping images. In one embodiment, an action camera captures two hyper-hemispherical fisheye images that are stitched to a 360° panorama. In order to remove exposure differences between the two cameras, the images are pre-processed prior to multiband blending. The pre-processing leverages image information from pixels to make informed guesses about pixels that were not captured. In particular, various pixels with different knowability (e.g., known, unknown, consistent, and conflicting) may be handled differently so as to emphasize/de-emphasize their importance in pre-processing.
