Embodiment 1
[0043] In Embodiment 1, we explained the metadata editing of dividing multimedia "content" including moving images and audio into a plurality of scenes, generating a hierarchical structure description of the scenes, and metadata (index information) including feature quantities of each scene device.
[0044] A metadata editing device related to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a metadata editing apparatus according to Embodiment 1 of the present invention. In addition, in each figure, the same code|symbol represents the same or a corresponding part.
[0045] In FIG. 1, a metadata editing device 100 is equipped with a "content" reproduction / display unit 2, a scene segmentation unit 3, a thumbnail image generation unit 4, a scene description editing unit 5, a text information adding unit 6, a feature extraction unit 7, User input unit 8 and metadata description unit 9 ....
Embodiment 2
[0071] In the first embodiment above, we described the case where all scenes are divided manually, but in the second embodiment, we describe a data editing device featuring a scene change detection unit that automatically detects scene change points.
[0072] A metadata editing device related to Embodiment 2 of the present invention will be described with reference to the drawings. Fig. 6 is a block diagram showing the configuration of a metadata editing device according to Embodiment 2 of the present invention.
[0073] In FIG. 6, metadata editing device 100A is equipped with "content" reproduction / display unit 2, scene segmentation unit 3, thumbnail image generation unit 4, scene description editing unit 5, text information adding unit 6, feature extraction unit 7, A user input unit 8 , a metadata description unit 9 and a scene change detection unit 39 . Also, reference numeral 40 is automatically detected scene start position information.
[0074] Next, the operation of t...
Embodiment 3
[0103] In this embodiment, we describe a metadata reproducing device that uses the metadata generated by the metadata editing device of the above-described first and second embodiments to perform image summary reproduction, search, and the like.
[0104] A metadata reproducing apparatus according to Embodiment 3 of the present invention will be described with reference to the drawings. Fig. 8 is a block diagram showing the configuration of a metadata reproduction apparatus according to Embodiment 3 of the present invention.
[0105] In FIG. 8, metadata editing device 200 includes metadata analysis unit 19, structure display unit 20, thumbnail image display unit 21, user input unit 22, search unit 23, search result display unit 24, summary generation unit 25, A summary structure display unit 26 and a “content” reproduction unit 27 .
[0106] The metadata analysis unit 19 analyzes the metadata 28 describing the hierarchical scene structure that "content" has, information on thu...
