Techniques are provided for converting live presentations into electronic media and managing captured media assets for distribution. An exemplary system includes capture devices that capture media assets of live presentations comprising a session, including image data of sequentially presented visual aids accompanying the live presentations and audio data. Each capture device has an interface for real-time image data marking of the image data for identification of individual images and session marking of the image data for demarcation of individual presentations of the session. A centralized device processes the captured media assets and automatically divides the captured media assets into discrete files associated with the individual presentations based on the session markings. An administrative tool manages the processed media assets to produce modified presentations and enables modification of the visual aid images identified by the image data markings. A production device formats the modified presentations for distribution on distribution media.

A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.

An image recording apparatus includes an image capturing unit configured to capture an image of a subject, a recording unit configured to record one of still image data and video image data captured by the image capturing unit on a storage medium in the form of an image file, a generating unit configured to generate a management file used for managing the image file recorded on the storage medium, and a registering unit configured to register an identifier of the image file recorded on the storage medium in the management file on a capture date basis in the order of capture time.

An image processing apparatus includes a storage storing images received from at least one camera, an image analyzer analyzing the images received from the at least one camera, separating an object, for which an event occurred, from a background, and extracting object properties information, a database storing the object properties information extracted with respect to each of the at least one camera, a search condition setter setting a search condition, a search engine searching the database for the object properties information matching the search condition, and obtaining image frames including the object properties information found from the storage, and a file generator generating a single image file by synthesizing the image frames.

A setting regarding a dynamic range is performed before image capturing, and in a case where a setting indicating a high dynamic range (HDR) is performed, RAW image data is recorded in association with development information corresponding to an HDR, and in a case where a setting indicating a standard dynamic range (SDR) is performed, RAW image data is recorded in association with development information corresponding to an SDR.

A video scene is displayed in a either a tag mode or a tagless mode. The video scene depicts a plurality of visually perceptible items. The tag mode displays one or more visually perceptible tags in conjunction with the video scene. Each tag is associated with a visually perceptible item appearing in the video scene. The tags are categorized into a plurality of categories. In response to a request to display the video scene in the tag mode for a first one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the first one of the categories. In response to a request to display the video scene in the tag mode for a second one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the second one of the categories.

A method, an image pre-processing apparatus, and a camera system for processing large images are provided. The method includes receiving from an image sensor an image frame at an image pre-processing apparatus, the image frame having a frame pixel resolution substantially equal to a sensor pixel resolution of the image sensor, dividing the image frame into first and second image subframes to be sequentially processed by an image signal processor, each of the first and the second image subframes having a subframe pixel resolution smaller than the sensor pixel resolution and a region in which the first and second image subframes overlap with each other. The subframe pixel resolution is predetermined by a processing capacity of the image signal processor, and the first and the second image subframes are consecutively processed by the image signal processor.

A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.

A video scene is displayed in a either a tag mode or a tagless mode. The video scene depicts a plurality of visually perceptible items. The tag mode displays one or more visually perceptible tags in conjunction with the video scene. Each tag is associated with a visually perceptible item appearing in the video scene. The tags are categorized into a plurality of categories. In response to a request to display the video scene in the tag mode for a first one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the first one of the categories. In response to a request to display the video scene in the tag mode for a second one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the second one of the categories.

A method, apparatus, and computer-readable medium display a video with a set of tags selectively overlaid on the video. The method causes a display device to display a sequence of video frames. The video depicts a plurality of visually perceptible items, and the video frames as displayed do not include any tags, thereby depicting the video in a tagless mode. The method also receives a signal requesting that the video be displayed in a tag mode. In response to receipt of said signal, the method overlays one or more visually perceptible tags on the video frames at specified positions, thereby causing the display device to display the video in a tag mode. Each of the overlaid tags is associated with at least one respective visually perceptible item appearing in the video.
