    摘要： This disclosure pertains to techniques for dynamically adapting image capturing techniques, e.g., based on shutter activation frequency, to improve camera responsiveness. One such technique is a method, comprising: receiving a first capture request; in response to receiving the first capture request, using a first capturing technique to capture a first set of images based on an image capture sequence, the image capture sequence comprising one or more images; generating a first image based on the captured first set of images; receiving a second capture request within a first time window from the first capture request, wherein a duration of the first time window is based, at least in part, on a length of time needed to capture the one or more images of the image capture sequence using the first capturing technique; in response to the received second capture request, using a second capturing technique to capture a second set of images, wherein the second capturing technique is different from the first capturing technique; and generating a second image based on the captured second set of images.

    摘要： Displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). Images represented in accordance with this disclosure are referred to as a dual-target images (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space. This approach minimizes pixel clipping when rendering a wide-gamut image for a narrow-gamut display, while allowing the original wide-gamut pixel values to be recovered when rendering for a wide-gamut display.

    摘要： In general, techniques are disclosed for displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). For this reason, an image represented in accordance with this disclosure is referred to as a dual-target image (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme described herein retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space. This approach minimizes pixel clipping when rendering a wide-gamut image for a narrow-gamut display, while allowing the original wide-gamut pixel values to be recovered when rendering for a wide-gamut display.

    摘要： Devices, methods, and non-transitory program storage devices are disclosed herein to provide improved region of interest (ROI) tracking, image framing, and distortion correction for wide field of view (FOV) video image streams. The techniques disclosed may be configured, such that the image framing decisions made over the course of a captured wide FOV video image stream are able to be panned smoothly and seamlessly transition between framing a narrower portion of a wide angle camera's FOV to framing a wider portion of the wide angle camera's FOV (or vice versa), e.g., depending on the composition and movement of relevant subjects in the captured scene. The techniques disclosed herein may also be used to perform any distortion correction desired on the framed image portions in the output video image stream, e.g., based on the image portions' FOVs and/or the locations of the portions within the original wide FOV video image stream.

    摘要： The subject technology determines input parameters and an output format of algorithms for a particular functionality provided by an electronic device. The subject technology determines an order of the algorithms for performing the particular functionality based on temporal dependencies of the algorithms, and the input parameters and the output format of the algorithms. The subject technology generates a graph based on the order of the algorithms, the graph comprising a set of nodes corresponding to the algorithms, each node indicating a particular processor of the electronic device for executing an algorithm. Further, the subject technology executes the particular functionality based on performing a traversal of the graph, the traversal comprising a topological traversal of the set of nodes and the traversal being based on a score indicating whether selection of a particular node for execution over another node enables a greater number of processors to be utilized at a time.
