Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technology for supporting a presentation by displaying and outputting document images to an audience, and more particularly to a technology that makes it possible to easily search for a desired document image from among a plurality of document images.
[0002]
[Prior art]
Services for distributing various contents to browsing clients such as personal computers and mobile terminals are widely implemented as specific area or wide area services.
There are various modes in such a content distribution system, but content data including video data is also distributed due to the development of network communication technology.
[0003]
The outline of the content distribution system is that various content data is registered in the distribution server, and when the browsing client accesses the distribution server to select and request a desired content, the distribution server responds to the content. It provides data to the browsing client.
[0004]
Such a system is a video data recording conferences, lectures, briefing sessions, etc. (in the present invention, these are called presentations) such as conferences, lectures, briefing sessions, presentations, etc. Is distributed as content, and is used for educational purposes, for example.
[0005]
[Problems to be solved by the invention]
The presentation proceeds while the presenter or his / her assistant acts as an operator to switch between many material images and present these material images to the audience. When these materials are prepared as image data, the title list and reduced image list of the document images to be used are displayed on the screen of the computer (presentation support device) placed at the operator's hand, and the operator can select from these lists. Is selected and presented to the audience by displaying a document image on the screen.
[0006]
These document image data are generally displayed in a list in the order in which they are to be used in advance, and the operator sequentially switches the display by selecting the document images from the list as the presentation progresses.
However, the presentation may not proceed as planned, and in such a case, the order of the material images to be used becomes unscheduled. In addition, when a series of presentations are completed and a question and answer session with the audience is performed, it is necessary to display necessary material images retrospectively. That is, it is required to quickly find and display a necessary material image from the list.
[0007]
In response to such a need, it is relatively easy to find a necessary material image when the number of material images prepared is relatively small, such as several sheets, but dozens of material images can be obtained. It is not uncommon to prepare and use an image, and it is difficult to quickly find a necessary one from such a large number of document images from a list display. In particular, when displaying a list of document images as reduced images, each reduced image occupies a relatively large area on the screen as compared to simply displaying a list of titles. In such a list display mode, the operator may have to turn the screen to see all the list displays. Therefore, the task of finding the necessary material images was extremely complicated.
[0008]
The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to allow an operator to quickly find a necessary material image in a presentation, thereby facilitating the progress of the presentation.
Further objects of the present invention will be apparent from the following description.
[0009]
[Means for Solving the Problems]
In the present invention, the presentation support device inputs a material file containing a plurality of types of material image data with the input means, and displays the material image displayed and output to the audience in the material file with the display means. At the same time, the remaining document images are displayed in a thumbnail list, and the search means performs a process of searching the thumbnail list for document images that match the search conditions input by the operator, and displays the document images for the audience. To help.
[0010]
A presentation support apparatus that performs such processing can be configured by executing a presentation support program on a computer.
It is preferable that the presentation support apparatus includes an operation input unit that receives an operator's selection input for a thumbnail image, and switches the material image input by the thumbnail selection to an image to be displayed and output to the audience.
[0011]

[0042]
As described above, the plurality of document image data used in the presentation is given the order information (default) to be used in advance, and in principle, it is displayed and used in the order according to the order information. In this presentation, the order of document images displayed on the screen is changed by the presenter operation described above, or a certain document image is repeatedly displayed on the screen, so that this can be reproduced with content data. The association unit 84 updates the order information (default) of each document image data according to the order actually used according to the input switching instruction.
Note that the switching instruction input from the presentation support apparatus 40 includes a document ID, and the association unit 84 grasps which document image data is switched at what time (timing) and performs the association process.
[0043]
Further, as shown in FIG. 7, each document image data before being actually used in the presentation is not associated with the video data 31 in time timing. Based on this, the time position for adding the use start timing (time on the time axis of the video data) is associated with each image data.
Here, since any document image is always displayed on the screen S in the presentation of this example, the time position of each document image data with respect to the video data 31 is specified only by defining the start timing of each document image. The It should be noted that the time position correspondence may be attached in a form such as a set of start timing and end timing or a set of start timing and usage time width.
[0044]
According to the associating device 80, the video data 31 recorded by the video input means 81 is inputted, the material image input means 82 is inputted the material image data 30 used in the presentation, and the switching instruction input means 83 is inputted in the presentation. A document image switching instruction made by the presenter P is input, and the association unit 84 can switch the input timing of the switching instruction with respect to the time axis based on the video data 31 based on these inputs. The association processing is set as the data display start timing, and further, the processing is performed to update the order information of each document image data in accordance with the order actually used according to the input switching instruction. In addition, the data file and the video data 31 subjected to the update process are stored in the data holding device 90. The process of force is made.
[0045]
By such processing by the associating device 80, the recorded video data 31 and the material image data used there are associated with each other in a correspondence relationship that reproduces the actual presentation, and these are collected in the archive file 25 and distributed. It will be registered in the server 1.
Therefore, in the browsing client 2 browsing the content distributed from the distribution server 1, the scene of the presentation and the material used there are displayed and output on the screen while reproducing the actual presentation.
[0046]
Note that the associating device 80, the data holding unit 90, and the editing device 100 may be configured as separate devices, or may be configured as a single device that integrates these device functions. For example, it can be configured by causing a computer to execute a program that implements a necessary processing function. In the case of an integrated configuration, the presentation support device 40, the file creation device 50, the file holding device 60, and the viewer 70 may also be included.
[0047]
The video data 31, the material image data 30, and the additional image data 33 collected as contents in the archive file 25 as described above are configured as shown in FIGS. 14 (a), 14 (b), and 14 (c).

The document image data 30 includes, in addition to the actual data forming the document image, its own document ID, the video ID of the associated video data, its own display start timing, its own data format type, and the actual usage order It contains information (real), keywords used for search, and the like.
The additional image data 33 includes, in addition to actual data that forms an additional image such as an arrow image or an animation image, its own additional image ID, the material ID of the associated material image data, its own display start timing, and the like. .
[0048]
FIG. 15 shows an example of an association relationship between the video data 31, the material image data 30, and the additional image data 33.
The video data 31 is continuous moving image data having a time width T. With respect to the time axis of the video data 31, a material image A having a time TA as a start timing, a material image B having a time TB as a start timing, and a time A document image C having a start timing of TC and a document image D having a start timing of time TD are associated with each other, and an arrow image a and a time Tb having a start timing of time Ta are associated with each document image 30. An animation image b having the start timing, an arrow image c having the time Tc as the start timing, and an arrow image d having the time Td as the start timing are associated with each other.
[0049]
Since the document image 30 is displayed on the screen from the start timing to the start timing of the next document image, the document image data 30 is represented as data having a certain time width in FIG. Only the display interval is shown, and the material image data of a still image that is not a moving image does not have a time width by itself.
The same applies to the additional image 33. In the same figure, only the display interval is shown, and the additional image data of a still image that is not a moving image does not have a time width by itself.
[0050]
Due to the correspondence between the document image 30 and the additional image 33, the display mode of the document image changes as time passes as shown in FIG.
That is, as shown in FIGS. 4A to 4D, when the start timing of the additional image is reached while the document images A, B, C, and D are displayed, the arrow image a and the animation image b are displayed. , The arrow image c and the arrow image d are superimposed on the set positions of the respective document images.
Therefore, such a synchronous display of the material image and the additional image is performed in the presentation, and is reproduced in the reproduction of the content while maintaining the time relationship.
[0051]
FIG. 17 shows a configuration of an editing apparatus 100 operated by an operator to edit video data 31 created for content.
The editing apparatus 100 receives data input means 101 for inputting content data (video data 31, material image data 30, additional image data 33) from the data holding apparatus 90, and an operator input for specifying a deletion portion in the video data 31. The input unit 102, the determination unit 103 for determining the time position of the material image data 30 associated with the video data portion 31a designated for deletion and the additional image data 33 associated with the material image, the deletion designated Deletion combination that deletes the video data portion 31a and recombines the video data 31 and updates the correspondence time positions of the material image data 30 and the additional image data 33 corresponding to the deletion portion 31a corresponding to the deletion portion 31a. Means 104, operator interface for editing processing Display means 105 for displaying, and an output means 106 for outputting the data content edited treated as an archive file 25.
[0052]
As shown in FIG. 18, the display unit 105 includes a player 110 for reproducing and displaying the video data 31 to be edited, material image data associated with the video data, and an additional image associated with the material image data. An operator interface including an editing interface 111 that visually represents the temporal position relationship with the data is displayed on the screen, and a designated input of the deletion portion 31a in the video data 31 is performed based on an operator instruction from the operation input means 102 for the editing interface 111. Accept.
[0053]
The editing interface 111 includes a time axis 112 indicating the time width of the video data 31, a material image mark (or thumbnail) 30a indicating the time position of the associated material image, and the time position of the associated additional image. When the operator designates and inputs a video portion to be deleted on the time axis 112 by clicking or dragging the mouse of the operation input means 102, the deletion target portion 31a of the video data is displayed. Is displayed, and when the operator presses the cut button 113 by an operation from the operation input unit 102, the deletion / combination unit 104 deletes the target portion of the designated video data and recombines the remaining portion.
Such a deletion instruction operation can be performed while confirming a video image with the video player 100, and can be performed while visually confirming the time-position relationship of data, thereby reducing the burden of operator work. .
[0054]
The deletion / combination means 104 deletes / recombines the designated portion of the video data 31 in response to the operator instruction input as described above. The deletion portion 31a of the video data 31 includes the display start timing position of the additional image data 33. In this example, several processing methods are possible.
As shown in FIG. 19A, the video data 31 in which the document image data 30 and the additional image data 33 are associated will be described by taking as an example the case where the portion of the time width Tcut is deleted from the time tcut on the video time axis. To do.
[0055]
This deletion portion Tcut includes the display start timing position tc of the additional image data (arrow c), and the method shown in FIG. 19B is one method of the deletion recombination processing.
This method shortens the display time of the document image C corresponding to the deleted portion Tcut and deletes the additional image indicated by the arrow c. That is, according to this method, the time position correspondence of the part (remaining part) in which the video data and the material image C are not deleted is maintained as it is.
[0056]
In the method shown in FIG. 19B, the additional image indicated by the arrow c is deleted, and the remaining portion after the deleted portion of the material image C is also deleted, so that the display start timing of the material image D subsequent to the material image C is deleted. This is a method of changing to the preceding time position tcut corresponding to the part. This method is a deletion and recombination method that places emphasis on the display of the additional image, and deletes a video image portion in which an action of pointing a certain item in the material image C with the arrow image c is performed. After the deleted portion, neither the arrow image c nor the material image C including the matter indicated by the arrow c has any significance for the content of the remaining video image, so it is deleted, and the next material image in which the next arrow image d appears. D is displayed in advance.

In general, the additional image is meaningful because there is a video image at the time when the additional image is displayed, and the material image after the additional image is displayed is meaningful only if there is the additional image. It can be said that the method shown in (2) performs deletion and recombination processing more in line with the actual presentation act.
Note that any of the above-described deletion recombination methods can be selected by an operator input and executed by the deletion combining unit 104.
[0058]
That is, according to the editing apparatus 100, the video data 31, the material image data 30 associated with the time position of the video data, and the additional image data 33 associated with the time position of the material image data are included. For the content, the operation input means 102 receives an operator input for designating a deletion portion in the video data, and the material determination means 103 applies the material image data associated with the video data portion designated for deletion and the material image. The time position of the associated additional image data is determined, and the deletion / combination means 104 deletes the video data portion designated to be deleted, recombines the video data, and the material image data corresponding to the deleted portion and the addition Processing to update the association time position of the image data corresponding to the deleted part is performed, and the edited Content data is output as an archive file 25.
If the editing device 100 does not perform special editing processing, the content data held in the data holding device 90 is output as the archive file 25 from the archive output means 106.
