An apparatus, system, and method allow a user to initiate a live stream that includes retrospectively captured images. Initiating the live stream includes providing provisional data that includes retrospectively captured images to a wireless radio.

A method for video frame analysis includes determining a first dissimilarity metric and a second dissimilarity metric. The first dissimilarity metric may correspond to a first difference between a first foreground of a first key frame in a video and a second foreground of a second key frame following the first key frame in the video. The second dissimilarity metric may correspond to a second difference between the second foreground of the second key frame and a third foreground of a third key frame following the second key frame in the video. A playback of the video may be generated based on the first dissimilarity metric and the second dissimilarity metric. Related systems and computer program products are also provided.

In one embodiment, a method includes writing a file into a data partition of a tape medium, writing a pointer of the written file in an index partition and creating a high resolution tape directory (HRTD) including detailed location information of data in a data partition. The method also includes storing the HRTD as part of end of data (EOD) of the index partition in response to a tape cartridge housing the tape medium being unloaded. The storing the HRTD as part of the EOD of the index partition includes requesting movement of the tape medium to the index partition in order to update an index file after changes have occurred to data in the data partition, writing an updated index file into the index partition concurrent to writing an updated HRTD into the EOD of the index partition, and requesting for the tape cartridge to be unloaded.

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.

A non-transitory computer-readable medium storing a data editing program causing a computer to execute data editing processing, the data editing processing includes transferring insert data between a transfer start position and a transfer end position to a transfer insertion position; the transferring the insert data including: transferring transfer-start-back-data at and after the transfer start position in a transfer start cluster to a first new cluster; transferring transfer-end-forward-data at and before the transfer end position in a transfer end cluster to a second new cluster; transferring transfer-insertion-forward-data at and before the transfer insertion position or transfer-insertion-back-data at and after the transfer insertion position to the first or the second new cluster; and editing the management data, such that a cluster next to the transfer start cluster is linked after the first new cluster, and a cluster preceding the transfer end cluster is linked before the second new cluster.

To enable an HDR image and an HDR image metadata to be stored in an MP4 file, and a reproduction device to reproduce an optimum HDR image based on metadata. In generating the MP4 file that stores HDR image data, the HDR image metadata is recorded in the MP4 file. An HDR image metadata storage box is set to a trak box or a traf box in the MP4 file, and the HDR image metadata is stored. The reproduction device acquires the HDR image metadata stored in the MP4 file, determines whether executing a conversion process of the HDR image read from. the MP4 file according to the acquired metadata and display function information of the display unit, and executes an output image generation process according to a determination result.

Disclosed is a system and method for controlling the playback speed, and user experience, of watching slow motion video content on a touch sensitive computing device such as a mobile phone, tablet or laptop with a touch sensitive screen. Key features of the disclosure are the simplicity of the user interface and the instant visual feedback given to the user.

Upon detection of a touch operation, an intensity of the touch is detected to calculate a provisional value of the touch intensity, and a video image to which a visual effect based on the provisional value is applied is displayed. Upon detection of removal of the touch, a definite value of the touch intensity is calculated and a confirmation screen for confirming whether to apply a visual effect based on the definite value is displayed.
