Embodiments of this application belong to the field of audio processing technologies and provide an audio processing method and an electronic device. The method is applicable to an electronic device including a camera. The electronic device records a plurality of channels of audio and video pictures corresponding to the audio in a video recording mode, and plays, during video playback, some video pictures and audio obtained after the plurality of channels of audio are combined. When a speaker in a video picture starts to speak, played audio is switched to audio corresponding to the video picture in which the speaker is located; thereby resolving a feeling of a sudden change of sound caused by switching required for obtaining audio content when the electronic device that does not support playback of a plurality of channels of audio plays a video.

A method of performing time-shift function and television receiver having a tuner and a personal video recorder for storing broadcast programs of at least one channel enables a broadcast program of a currently tuned channel to be continuously and efficiently stored to enable time-shifting, regardless of an interruption by switching channels or changing input sources or even in the case of an inadvertent power-off condition. The method includes steps of setting a time-shift lock function; storing in the personal video recorder the broadcast program of a first channel that is currently viewed; storing in the personal video recorder the broadcast program of a second channel and the broadcast program of the first channel, if the currently viewed first channel is switched to the second channel; and supplying power only to the tuner and the personal video recorder, if a power-off condition occurs, wherein the supply of power to the tuner and the personal video recorder causes a continuous storing of the broadcast programs of the first and second channels in the personal video recorder.

An image processing apparatus that handles RAW images efficiently performs editing for reproducing RAW images.

The apparatus compresses each of RAW images and reduced RAW images which are reduced from the RAW images, and records each in a recording medium. When editing, the image processing apparatus communicates with an external apparatus and transmits the reduced RAW images stored in the recording medium to the external apparatus, and causes the external apparatus to perform editing processing of the reduced images. Further, the image processing apparatus uses editing information representing the content of editing processing from the external apparatus to execute editing of the RAW image corresponding to the reduced RAW image on which the editing processing has been performed, by referencing the editing information.

A method for processing video data is performed by a data processing unit (DPU). The method includes identifying, by the DPU of an edge device, a contextual stitching trigger event; in response to identifying the contextual stitching trigger event: identifying video data chunks, contextual metadata, indexing metadata, and authentication and authorization (AA) metadata associated with the contextual stitching trigger event; generating a virtual blob based on the video data chunks, contextual metadata, indexing metadata, and authentication and authorization AA metadata; making a first determination that a playback request is obtained from a user, wherein the playback request comprises user authentication information; and in response to the first determination: making a second determination that the user authentication information matches the AA metadata; and in response to the second determination; encoding the video data chunks into a single stream and initiating playback for the user.

An image processing apparatus that handles RAW images favorably performs display when shooting and display when reproducing. The apparatus images a subject and generates RAW images, and reduces the RAW images and generates reduced RAW images, The RAW images and reduced RAW images are recorded in a recording medium. When shooting, the reduced RAW images are subjected to developing processing for display, and when reproducing, the reduced raw images recorded in the recording medium are acquired and subjected to developing processing in accordance with instructions to reproduce, and each is used for display.

A device and method are presently disclosed. The computer implemented method, includes at an electronic device with a touch-sensitive display, displaying a still image on the touch-sensitive display, while displaying the still image, detecting user's finger contact with the touch-sensitive display, and in response to detecting the user's finger contact, video recording the still image.

Various embodiments of the present invention relate generally to systems and processes for transforming a style of video data. In one embodiment, a neural network is used to interpolate native video data received from a camera system on a mobile device in real-time. The interpolation converts the live native video data into a particular style. For example, the style can be associated with a particular artist or a particular theme. The stylized video data can viewed on a display of the mobile device in a manner similar to which native live video data is output to the display. Thus, the stylized video data, which is viewed on the display, is consistent with a current position and orientation of the camera system on the display.

A video processing device connectable with a recorder includes a first receiver and a controller. The first receiver receives a main video signal containing two or more frames which are consecutive in time sequence, the main video signal produced by imaging two or more subjects including at least one moving subject. The controller generates one or more sub video signals produced by imaging a first subject of the plurality of subjects, from the main video signal. The controller generates main video data including the main video signal and first association information specifying the one or more sub video signals generated from the main video signal. Furthermore, the controller generates one or more sub video data including the one or more sub video signals and second association information specifying the main video signal from which the one or more sub video signals have been generated. The controller makes a recorder store the main video data and the one or more sub video data.

A method includes recording a first video stream characterized by a first value of a first quality characteristic. The method includes determining that the first video stream satisfies a trigger criterion. The trigger criterion characterizes a threshold amount of video content change information. The method includes, in response to determining that the first video stream satisfies the trigger criterion, obtaining a second video stream characterized by a second value of a second quality characteristic. The second video stream includes scene information also included in the first video stream. The second value of the second quality characteristic is indicative of a higher quality video stream than the first value of the first quality characteristic. The method includes generating a third video stream by adding information from the second video stream to the first video stream. The third video stream corresponds to a higher quality version of the first video stream.

The present technology relates to a file generation device, a file generation method, a file reproduction device, a file reproduction method, and a program capable of associating an image stored is a file with external data outside the file.

A file control unit generates an association-type high efficiency image file format (HEIF) file in which an image in an HEIF file compliant with HEIF and specific information that specifies external data outside the HEIF file, the external data to be associated with the image, are stored in association with each other. Furthermore, the file control unit reproduces the association-type HEIF file. The present technology can be applied to a case where an HEIF file is generated or a case where the HEIF file is reproduced.
