Abstract: An electronic device having a display and a touch-sensitive surface displays a mediate item representation corresponding to a sequence of images in a first display mode of user-selectable display modes, where the media item is part of a collection of ordered media items such that prior media item(s) precede the first media item and subsequent media item(s) follow the first media item in the order. In response to detecting touch input including movement in a direction, the device: upon determining that a subsequent media item corresponding to a second sequence of images is designated as being displayed in the first display mode, displays the subsequent media item in the first display mode, and upon determining that the subsequent media item is designated as being displayed in a second display mode different from the first display mode, displays the subsequent media item in the second display mode.

Abstract: An electronic device having a camera, while displaying a live preview for the camera, detects activation of a shutter button at a first time. In response, the electronic device acquires, by the camera, a representative image that represents a first sequence of images, and a plurality of images after acquiring the representative image, and also displays an indication in the live preview that the camera is capturing images for the first sequence of images. The electronic device groups images acquired by the camera in temporal proximity to the activation of the shutter button at the first time into the first sequence of images, such that the first sequence of images includes a plurality of images acquired by the camera prior to detecting activation of the shutter button at the first time, the representative image, and the plurality of images acquired by the camera after acquiring the representative image.

Abstract: An image editing user interface, displayed by a computer system, for editing a sequence of images (e.g., an enhanced digital image), includes an affordance for turning on, or off, animated playback of the sequence of images, while retaining the sequence of images. While animated playback is turned off, a representative image from the sequence of images is displayed.

Abstract: An electronic device having a display and a touch-sensitive surface displays, in a user interface, image(s) from a media item corresponding to a sequence of images in a display mode. In response to an input, the device displays an editing user interface that changes which images are included in the media item when the media item is displayed in the display mode, including concurrently displaying: an area display images in the sequence of images; another distinct area including representations of images in the sequence of images, a user-adjustable begin-trim affordance indicating a first boundary for playback through the sequence of images, and a user-adjustable end-trim affordance indicating a second boundary for playback through the sequence of images. The device further adjusts the media item, exits the editing user interface in response to an input, and displays the edited media item in the display mode in the user interface.

Abstract: An electronic device displays, in a first user interface, a media item that corresponds to a sequence of images in a first display mode, which is one of a plurality of user-selectable display modes for the media item. The device, responsive to detecting an input, displays a display-mode selection user interface that concurrently displays representations of the media item, including a second representation of the media item that corresponds to a second display mode. The device detects an input on the second representation in the plurality of representations of the media item. In response, the device selects a second display mode in the plurality of user-selectable display modes for the media item, which corresponds to the second representation in the plurality of representations of the media item.

Abstract: An electronic device displays a representative image. While displaying the representative image, the device detects a first input. In response to the first input, the device transitions from displaying the representative image to displaying a respective image that was acquired by a camera before acquiring the representative image. After transitioning from displaying the representative image to displaying the respective image, the device displays, in sequence starting with the respective image, at least some images acquired by the camera before acquiring the representative image and at least some of images acquired by the camera after acquiring the representative image. The device detects termination of the first input. In response to detecting termination of the first input, the device displays the representative image.

Abstract: Techniques and devices for generating multiple output video variations for an input video based on a shared resource architecture. The shared resource architecture reuses and shares computational and gating results from one or more operations to create the multiple output video variations. The shared resource architecture applies a frame-time normalization of the trimmed and stabilized video to produce a trimmed stabilized normalized video and, thereafter, uses the trimmed stabilized normalized video to precompute one or more video parameters that can be shared with multiple output video variations. The shared resource architecture can then generate multiple output video variations using the shared video parameters.

Abstract: In various implementations a method includes obtaining a plurality of source images, stabilizing the plurality of source images to generate a plurality of stabilized images, and averaging the plurality of stabilized image to generate a synthetic long exposure image. In various implementations, stabilizing the plurality of source images includes: selecting one of the plurality of source images to serve as a reference frame; and registering others of the plurality of source images to the reference frame by applying a perspective transformation to others of the plurality of the source images.

Abstract: An electronic device displays an image in a sequence of images. The sequence of images includes a representative image and images acquired by the camera before and after acquiring the representative image. While displaying the image, the device detects a first input and, in response, displays a user interface for trimming the sequence of images. The user interface includes: representations of images in the sequence of images; a begin-trim icon that delimits a beginning image in the subset of the sequence of images; and an end-trim icon that delimits an ending image in the subset of the sequence of images. The begin-trim and end-trim icons are located at positions that are automatically selected by the device. The device detects a second input and, in response, trims the sequence of images to the subset of the sequence of images based on the positions of the begin-trim and the end-trim icons.

Abstract: Techniques and devices for creating a Forward-Reverse Loop output video and other output video variations. A pipeline may include obtaining input video and determining a start frame within the input video and a frame length parameter based on a temporal discontinuity minimization. The selected start frame and the frame length parameter may provide a reversal point within the Forward-Reverse Loop output video. The Forward-Reverse Loop output video may include a forward segment that begins at the start frame and ends at the reversal point and a reverse segment that starts after the reversal point and plays back one or more frames in the forward segment in a reverse order. The pipeline for the generating Forward-Reverse Loop output video may be part of a shared resource architecture that generates other types of output video variations, such as AutoLoop output videos and Long Exposure output videos.
