Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system diagram showing the configuration of a multimedia content generation system according to one embodiment of the present invention.

As shown in FIG. 1, a multimedia content generation system according to an embodiment of the present invention includes an edit processing server 10 and a terminal device 20 such as a personal computer (hereinafter abbreviated as personal computer) interconnected by a network 30. , and a video camera 40 .

The multimedia content generation system of this embodiment generates multimedia content by combining various contents such as moving images, still images, voices, and characters. According to the multimedia content generation system of the present embodiment, for example, moving images of lectures and explanations using presentation materials are captured in advance, and multimedia content is generated in which presentation materials are switched in synchronization with which moving images. can be generated. In addition, it is possible to generate multimedia content in which static images, arrows, descriptive images using characters, voices, etc. are played back in synchronism with moving images for explaining equipment maintenance, assembly procedures, and the like.

The editing processing server 10 is an information processing device in which editing software for editing such various contents and generating multimedia contents is installed. Then, the terminal device 20 captures moving image data captured by the video camera 40 and uses editing software operating on the editing processing server 10 to generate multimedia content.

Instead of installing such editing software on the editing processing server 10, it is also possible to install it directly on the terminal device 20 such as a personal computer and use it.

Next, FIG. 2 shows the hardware configuration of the editing processing server 10 in the image forming system of this embodiment.

As shown in FIG. 2, the editing processing server 10 exchanges data with an external device such as a terminal device 20 via a CPU 11, a memory 12, a storage device 13 such as a hard disk drive (HDD), and a network 30. It has a communication interface (IF) 14 for transmission and reception, a user interface (UI) device 15 including a touch panel or liquid crystal display, and a keyboard. These components are connected to each other via a control bus 16 .

The CPU 11 executes predetermined processing based on a control program stored in the memory 12 or storage device 13 to control the operation of the editing processing server 10 . In this embodiment, the CPU 11 reads and executes a control program stored in the memory 12 or the storage device 13. It is also possible to provide

FIG. 3 is a block diagram showing the functional configuration of the edit processing server 10 realized by executing the above control program.

The edit processing server 10 of this embodiment comprises a data communication section 31, a control section 32, and a multimedia data storage section 33, as shown in FIG.

The data communication unit 31 performs data communication with the terminal device 20 via the network 30 .

The control unit 32 controls the operation of the editing processing server 10 and includes a user operation reception unit 41, an operation mode switching unit 42, a display control unit 43, a moving image reproduction unit 44, and a confirmation unit 45. ing.

The multimedia data storage unit 33 stores various content data such as moving image data, still image data, audio data, etc. to be edited.

The user operation accepting unit 41 also accepts an instruction to set the time to change the display content of the still image in synchronization with the reproduction of the moving image. The instruction to set the time to change the display content of the still image is, more specifically, an instruction to set the switching timing for switching a still image such as a presentation material to the next page (page), or an arrow, text, etc. in the still image. is an addition timing setting instruction for adding a display object (display element).

That is, the user operation reception unit 41 issues a setting instruction (command) such as switching the still image to be displayed from page 2 to page 3 after how many minutes and seconds after the start of playback of the moving image, A setting instruction is accepted, such as where a display object such as an arrow or a character is to be added to the displayed still image after a minute and a second.

Then, when the operation mode switching unit 42 receives an instruction to set the time for changing the display content of the still image from the user operation reception unit 41, the operation mode switching unit 42 changes the operation mode (operation state) to the time for changing the display content of the still image. , to an adjustment mode (adjustment state) for adjusting the time for changing the display content of the still image.

Here, the screen displayed in the setting mode for setting the time for changing the display content of the still image is called a preview screen, and the screen displayed in the adjustment mode for adjusting the time for changing the display content of the still image is It is called the command position adjustment screen.

On this preview screen, a plurality of still images to be switched and displayed are displayed while a moving image is being played back. can be done. Also, on the preview screen, while playing back a moving image, by selecting a display object to be added to a still image and specifying the display position, it is now possible to specify the timing for adding the display object. ing.

Before the operation mode switching unit 42 switches the operation mode from the setting mode to the adjustment mode, the confirmation unit 45 confirms with the user whether or not to shift to the adjustment mode. It should be noted that when the operation mode is switched from the setting mode to the adjustment mode, the confirmation process may be always performed by the confirmation unit 45 according to preset setting contents, or such confirmation process may not be performed. You can do it.

Then, when confirmation by the confirmation unit 45 is performed in this way, the operation mode switching unit 42 operates from the setting mode to the adjustment mode when the confirmation unit 45 permits the shift to the adjustment mode by the user. Switch modes.

In the adjustment mode, the moving image reproduction unit 44 extracts and reproduces a moving image of a preset reproduction interval including the time when a setting instruction is given to change the display content of the still image.

For example, the moving image reproducing unit 44 extracts a section of several seconds before and after the time at which the setting instruction to change the display content of the still image is given as the reproduction section, and reproduces the moving image of the extracted reproduction section as a still image. Playback is repeated until the adjustment of the time to change the display content of the image is completed.

Further, the moving image reproduction unit 44 reproduces the moving image of the extracted reproduction section at a reproduction speed slower than the moving image reproduction speed in the setting mode for setting the time for changing the display content of the still image.

In addition, the moving image reproduction unit 44 reproduces the moving image of the extracted reproduction section at a plurality of different reproduction speeds.

Specifically, the moving image reproduction unit 44 reproduces the moving image of the extracted reproduction section at a slower reproduction speed as the reproduction section is closer to the time when the setting instruction to change the display content of the still image is issued.

The display control unit 43 controls screens displayed on the terminal device 20 . In the adjustment mode, the display control unit 43 displays a seek bar (playback position display image) indicating the playback position in a preset playback interval including the time when a setting instruction was given to change the display content of the still image. control so that

In addition, the display control unit 43 displays the seek bar so that the time intervals of the seek bar are different from the time when the setting instruction to change the display content of the still image is given.

Specifically, the display control unit 43 displays the seek bar so that the time interval of the seek bar becomes longer as the time interval nearer to the time at which the setting instruction to change the display content of the still image is issued.

In addition, in the adjustment mode, the display control unit 43 displays a text image (character image) of the voice in a preset reproduction section including the time at which the setting instruction to change the display content of the still image is performed. to control.

Then, the moving image reproduction unit 44 reproduces the moving image in different reproduction modes depending on whether or not the display control unit 43 controls to display the character image of the voice. Specifically, when the display control unit 43 controls to display the character image of the voice, the moving image reproduction unit 44 reproduces the moving image in a pause state. Note that the moving image reproduction unit 44 repeatedly reproduces the moving image of the extracted reproduction section when the display control unit 43 does not control the character image of the voice to be displayed.

Furthermore, in the adjustment mode, the display control unit 43 performs control so that an image indicating the audio level in a preset reproduction section including the time when a setting instruction is given to change the display content of the still image is displayed. You can do it.

The display control unit 43 determines whether the current operation mode is a setting mode for setting the time for changing the display contents of the still image in synchronization with the reproduction of the moving image or the adjustment mode described above. Control the display so that it is easy to understand.

Finally, the operation mode switching unit 42 switches the operation mode from the adjustment mode to the setting mode when the operation of the user indicates that the adjustment of the time for changing the display content of the still image has been completed.

Alternatively, the operation mode switching unit 42 may switch the operation mode from the adjustment mode to the setting mode when the reproduction of the extracted reproduction section is completed without the user's instruction.

Next, the operation of the edit processing server 10 in the multimedia content generation system of this embodiment will be described in detail with reference to the drawings.

First, the outline of moving images in the editing processing server 10 will be described with reference to the flowchart of FIG.

For example, when the edit processing server 10 displays a preview screen as shown in FIG. It is explained assuming that there is (yes in step S102).

In the display screen example of the preview screen shown in FIG. 6, the user gave a page switching instruction to switch the presentation material displayed at the playback time of the moving image of 30.0 seconds from the first page to the second page. case is shown.

When such a page switching instruction is issued, the editing processing server 10 changes the operation mode from the setting mode to the adjustment mode, and switches the screen displayed on the terminal device 20 from the preview screen to the command position adjustment screen ( step S103).

An example of such a command position adjustment screen is shown in FIG. In the command position adjustment screen shown in FIG. 7, along with the displayed still image, playback of 25.0 to 35.0 seconds, which is five seconds before and after the playback time of 30.0 seconds at which the page switching instruction was performed, is displayed. A section is extracted, and the moving image in the extracted playback section is repeatedly played back.

The command position adjustment screen shown in FIG. 7 includes a seek bar 53 for indicating the playback position in the extracted playback segment, a text image 51 that converts the voice in the playback segment into text, and the audio level of the voice in the playback segment. Image 52 is displayed (step S104).

By referring to the text image 51, the voice level image 52, and the seek bar 53 thus displayed, the user can finely adjust the switching timing for switching the first page of the presentation material to the second page.

Then, on this command position adjustment screen, reproduction of the extracted reproduction section is repeated until the command position for instructing page switching is determined (steps S105 and S106).

In the command position adjustment screen shown in FIG. 7, the characters "Command position is being adjusted." is being done.

Then, when the command position for instructing page switching is determined by the user (yes in step S106), command position addition processing is performed in the editing processing server 10 (step S107).

Then, the operation mode returns to the setting mode, the displayed screen returns to the preview screen, and the reproduction of the moving image is continued (step S101).

A setting example of the reproduction speed of the seek bar 53 on the command position adjustment screen shown in FIG. 7 will be described with reference to FIG.

In the setting example of the playback speed shown in FIG. 8, when the playback speed on the preview screen is set to 1, the playback speed in the section from -1 to +1 seconds is set to 1/5 (1/5), and -2 The playback speed for the section from -1 second and the section from +1 to +2 seconds is set to 1/3 (1/3), and the playback speed for the section from -3 to -2 seconds and the section from +2 to +3 seconds is set to 2. It is shown when set to one minute (1/2).

Since the playback speed of the seek bar 53 is set as described above, the time interval of the seek bar 53 is changed to the time (0:00:30.00) at which the setting instruction was given to change the display content of the still image. seconds) is set to be longer.

Then, as shown in FIG. 9, when the user refers to the text image 51, the sound level image 52, the seek bar 53, etc., and selects the second page of the presentation material at the playback time of 28.4 seconds, this playback Time 28.4 seconds will be selected as the position to add the page switch command.

Therefore, as shown in FIG. 10, "playback time 0:00:28.4" is added as the page switching command position. After the command position is added, the displayed screen is switched from the command position adjustment screen to the preview screen as shown in FIG. 11, and the reproduction of the moving image is continued.

In the present embodiment, the case where the extracted playback interval is repeatedly played has been described. The command addition position may be finely adjusted by referring to the image 52 .

That is, on the command position adjustment screen as shown in FIG. You can see that you can specify the command addition position between the texts "I'm going to this".

When the text image 51 of such voice is displayed, the moving image may be reproduced in a pause state instead of being repeatedly reproduced. When the audio text image 51 is displayed, the user can use only this text image 51 to determine the position at which page switching should be performed without viewing the moving image. On the contrary, it is easier to specify the position where the page switching command is added when the image is in the paused state.

If the moving image data does not include voice text data, text data is generated by performing voice recognition processing on the voice data, and the generated text data is displayed as a text image 51. You should do it like this.

Also, when an instruction to add a command is given on the preview screen, instead of immediately switching to the command position adjustment screen, it is possible to confirm with the user whether or not it is okay to transition to the command position adjustment screen. An example of the display screen is shown in FIG.

In the example of the display screen shown in FIG. 12, when the user selects the second page of the presentation material on the preview screen and specifies the page switching position, the text "Do you want to transition to the command position adjustment screen?" is displayed. The case is shown. If the user selects "yes", the command position adjustment screen is displayed, and if the user selects "no", the control returns to the original preview screen without transitioning to the command position adjustment screen. done. Such confirmation processing when transitioning to the command position adjustment screen is effective in the following cases.

For example, if the page switching timing should be approximately synchronized with the reproduction of the moving image, there is no need to bother to display the command position adjustment screen and perform fine adjustment of the command position. Therefore, in such a case, the position of the next command should be set without displaying the command position adjustment screen. Conversely, if the page switching timing needs to be strictly synchronized with the reproduction of the moving image, the command position adjustment screen can be displayed to perform fine adjustment of the command position.

In the above description, the case of adding a command for page switching has been described, but similar operation mode switching is also performed when adding a command other than page switching.

For example, as shown in FIGS. 13(A) to 13(D), when generating multimedia content in which an arrow-shaped display object 61 is sequentially moved and displayed on the presentation material. However, if the command addition timing is set, control should be performed such that the operation mode is switched from the setting mode to the adjustment mode.
