  The present invention relates to a content editing apparatus, method, and program, and more particularly, to a content editing apparatus, method, and program that enable anyone to easily perform advanced editing.

  2. Description of the Related Art Conventionally, a technology for content editing has been proposed in which a plurality of images as materials are connected to generate one moving image content. Also, due to the price reduction of camcorders and recorders, tools such as software that can easily edit video content are also becoming popular in ordinary households.

  When editing content, when displaying information related to images and sound, not only numerical values and images are displayed as they are, but also a display method that is easy to understand visually, such as timeline display, has been devised. ing.

  In content editing using the timeline display, one video is usually specified by specifying the IN point and OUT point of image data as a plurality of materials on a GUI screen or the like where the horizontal axis is time. Content is generated.

  Conventionally, an example of displaying a waveform image such as an audio signal or a change in luminance value of a pixel is known as a timeline display.

  Also, by assigning a subtitle setting box in the timeline display area, it is possible to easily determine whether or not the subtitle playback period is appropriate, so that one subtitle data can be created by multiple people. Technology has also been proposed (see, for example, Patent Document 1).

  According to the present invention, anyone can easily perform advanced editing.

It is a block diagram which shows the structural example of the content editing apparatus which concerns on one embodiment of this invention. It is a figure which shows the example of the screen of GUI displayed in the case of the edit operation process in a content editing apparatus. It is a figure explaining the example of the edit by the conventional timeline display. It is a figure explaining the example of the edit by this invention. It is a flowchart explaining the example of an edit operation process. It is a flowchart explaining the example of a content file creation process. And FIG. 16 is a block diagram illustrating a configuration example of a personal computer.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a content editing apparatus 10 according to an embodiment of the present invention.

  In the example shown in the figure, the content editing apparatus 10 is provided with a material image supply unit 21, an audio supply unit 22, an operation input unit 23, an image reproduction unit 24, an audio reproduction unit 25, an operation recording unit 26, and a timer 27. . Further, the content editing apparatus 10 is provided with a capture processing unit 31, an encoder 32, an image display unit 33, and an audio output unit 34.

  The content editing apparatus 10 is configured to generate content data (hereinafter referred to as a content file) in which images serving as materials are sequentially switched over audio or music. First, the user performs an editing operation process for performing an operation of sequentially switching images as materials while listening to voice or music using the content editing apparatus 10. Thereafter, a content file generation process for generating a content file in which audio data and image data are integrated is performed.

  The material image supply unit 21 accumulates image data arranged in the order of reproduction in advance, and supplies the image data to the image reproduction unit 24 based on the operation signal supplied from the operation input unit 23. . The image data may be, for example, still image data encoded by the JPEG method, or may be moving image data encoded by the MPEG method.

  The image data stored in the material image supply unit 21 is referred to as a material image. The material image accumulation will be described later.

  For example, when a predetermined key (not shown) connected to the operation input unit 23 is pressed, an operation signal is output to the material image supply unit 21. Thus, the material image supply unit 21 supplies the image reproduction unit 24 with the image data in the next order of the image data that has been supplied to the image reproduction unit 24 until then.

  The image reproduction unit 24 reproduces the image data supplied from the material image supply unit 21 based on the operation signal supplied from the operation input unit 23 by decoding the image data. For example, when an operation signal corresponding to a reproduction start command is supplied from the operation input unit 23, the image reproduction unit 24 starts reproduction processing of image data supplied from the material image supply unit 21. When the operation signal corresponding to the reproduction end command is supplied from the operation input unit 23, the reproduction process of the image data supplied from the material image supply unit 21 is ended.

  The audio supply unit 22 accumulates audio data that has been specified in advance and is encoded in a predetermined format (for example, mp3). Based on the operation signal supplied from the operation input unit 23, the audio supply unit 22 Data is supplied to the audio reproduction unit 25. The audio data may be, for example, a copy of a song recorded on a CD or the like, or may be reproduced according to a playlist.

  For example, when a predetermined key described above of a keyboard (not shown) connected to the operation input unit 23 is pressed, an operation signal is output to the sound supply unit 22 together with the material image supply unit 21. Thereby, the audio supply unit 22 supplies the audio data to the audio reproduction unit 25. That is, the supply of audio data is started, and the supply of image data of the first material image is started, so that the audio data and the image data are supplied synchronously. Yes.

  The audio reproduction unit 25 reproduces the audio data supplied from the audio supply unit 22 based on the operation signal supplied from the operation input unit 23 by decoding it. For example, when an operation signal corresponding to a reproduction start command is supplied from the operation input unit 23, the audio reproduction unit 25 starts reproduction processing of audio data supplied from the audio supply unit 22, When the operation signal corresponding to the reproduction end command is supplied from the operation input unit 23, the reproduction process of the audio data supplied from the audio supply unit 22 is ended.

  In the editing operation process, the image data reproduced by the image reproduction unit 24 is supplied to the image display unit 33. The image display unit 33 generates an image signal by combining the image data reproduced by the image reproduction unit 24 and the GUI image data as necessary, and outputs the image signal to a display (not shown). Yes. Thereby, the user can view the images in which the material images are sequentially reproduced.

  In the editing operation process, the audio data reproduced by the audio reproducing unit 25 is supplied to the audio output unit 34. The audio output unit 34 generates an audio signal based on the audio data reproduced by the audio reproduction unit 25 and outputs the audio signal to a speaker (not shown). Thereby, the user can listen to the reproduced voice and music.

  That is, when the editing operation process by the content editing apparatus 10 is started, the user switches the material image while viewing the reproduced material image displayed on the display while listening to the sound or music output from the speaker. Is specified via the operation input unit 23.

  When the editing operation process by the content editing apparatus 10 is started, the timer 27 starts timing, and the timed information is output to the operation recording unit 26.

  The operation recording unit 26 is an operation signal output from the operation input unit 23 and records an operation signal instructing switching of a material image as operation information in association with time. That is, switching to the second material image is instructed XX seconds after the start of the reproduction of the first material image, and switching to the third material image is instructed after ΔΔ seconds, Information such as... Will be recorded.

  When the content file generation process by the content editing apparatus 10 is started, the operation recording unit 26 outputs an operation signal corresponding to the recorded operation information. That is, the operation recording unit 26 is instructed to switch to the second material image XX seconds after the start of the reproduction of the first material image, and to the third material image △ Δ seconds later. Is switched, and an operation signal is output as shown in FIG.

  Thereby, the material image supply unit 21 sequentially supplies the image data of the material image to the image reproduction unit 24, and the image reproduction unit 24 reproduces this. Similarly, the audio supply unit 22 supplies audio data to the audio reproduction unit 25, and the audio reproduction unit 25 reproduces it.

  When the content file generation process is executed, the image reproduced by the image reproduction unit 24 is not displayed on the display, and the sound reproduced by the audio reproduction unit 25 is not output from the speaker. When the content file generation process is executed, for example, the playback rate of the image playback unit 24 and the playback rate of the audio playback unit 25 are set to be twice the normal playback rate.

  As described above, in the content editing apparatus 10, only the operation information is recorded in the editing operation process, and the content file is not generated.

  By doing so, for example, it is possible to reduce the processing load of a processor or the like built in the content editing apparatus 10, and it is possible to suppress the occurrence of noise or the like when switching images.

  In addition, after the editing operation process is completed, for example, in order to confirm the quality of the editing operation, a preview process for reproducing an image and a sound based on the operation information is performed without generating a content file. It doesn't matter.

  In the content file generation process of the content editing apparatus 10, the capture processing unit 31 captures the data output from the image playback unit 24 and the data output from the audio playback unit 25.

  The capture processing unit 31 outputs the captured data to the encoder 32, and the encoder 32 encodes (encodes) the data output from the capture processing unit 31 in a predetermined format (for example, a method such as MPEG or WMV). It is made like that. As a result, one content file composed of sound and images viewed by the user in the editing operation process is generated.

  By doing in this way, the user can produce | generate the content from which an image changes according to BGM, for example. By using the content editing apparatus 10, for example, it is also possible to create a promotion video or the like using an image taken by an amateur music group and a piece of music performed by the amateur music group.

  FIG. 2 is a diagram showing an example of a GUI screen displayed on a display (not shown) during the editing operation process in the content editing apparatus 10. The screen is configured such that display data is generated and displayed by the material image supply unit 21 based on a user operation input via the operation input unit 23, for example.

  In the screen 100 shown in the figure, a scenario window 101 for displaying a list of image data stored in the material image supply unit 21 is provided. In this example, thumbnails 111-1 to 111-6 of each image data are displayed in the scenario window 101.

  Note that, as described above, the material image supply unit 21 stores image data arranged in advance in the order of reproduction, and in the drawing, corresponds to the image data corresponding to the thumbnail 111-1 and the thumbnail 111-2. The image data to be reproduced are arranged in order of image data corresponding to the thumbnail 111-6.

  For example, the order of the image data can be rearranged by the user operating a pointing device (not shown) and dragging and dropping thumbnails. Further, by clicking a button 105 in the figure, image data recorded on a removable medium or the like can be copied and stored in the material image supply unit 21. That is, the user can add, delete, or rearrange the image data of the material image.

  As described above, the user can confirm the reproduction order of the image data as the material by the thumbnails displayed in the scenario window 101.

  The screen 100 is provided with a material window 102. The material window 102 is a window displayed when the image data stored in the material image supply unit 21 is processed. For example, when the user double-clicks one of the thumbnails displayed in the scenario window 101, the material window 102 is displayed. Then, while viewing the image of the image data displayed on the display unit 104, the user operates the GUI parts such as buttons and bars displayed on the palette 103 to trim, cut, Processing such as rotation can be performed.

  As described above, when the editing operation process by the content editing apparatus 10 is started, the audio reproduction unit 25 decodes the audio data supplied from the audio supply unit 22 and reproduces it. The image reproduction unit 24 reproduces the image data supplied from the material image supply unit 21 by decoding the image data. At this time, in the scenario window 101, for example, the thumbnail 111-1 of the image data to be reproduced first is highlighted in the center and displayed. The image obtained by reproducing the image data of the thumbnail 111-1 is displayed on the display as a part of the screen 100 or a screen different from the screen 100, for example.

  When the user presses a predetermined key (not shown) connected to the operation input unit 23, the reproduction of the image data corresponding to the thumbnail 111-2 is started. At this time, the audio data is continuously reproduced.

  Conventionally, when displaying information related to images and audio when editing content, not only numerical values and images are displayed as they are, but also a display method that is visually easy to understand, such as timeline display, for example. Has been devised.

  In content editing using the timeline display, one video is usually specified by specifying the IN point and OUT point of image data as a plurality of materials on a GUI screen or the like where the horizontal axis is time. Content is generated.

  However, as in the prior art, the method of connecting images as materials based on a timeline display with a time axis set cannot perform advanced editing like a professional editor.

  That is, editing such as switching the image as a material in accordance with BGM or the like cannot be performed well.

  For example, in a promotional video of music edited by a professional editor, images are often switched in synchronization with the progress of the music. In addition, in a particularly high part of music, the image may be switched in synchronization with the time of percussion such as a cymbal.

  For example, if the tempo of a 4/4 time tune is 120 BPM (Beats Per Minute), the length of one beat is 0.5 seconds, but if the music is played with a rhythm such as shuffle or swing, The time length of each beat is different. In addition, when a performance incorporating a technique such as syncopation is performed, it is extremely difficult to specify the timing synchronized with the music on the time axis visually displayed on the screen.

  For this reason, even if the moving image content is edited using a conventional personal editing tool or the like, when the completed moving image content is reproduced, it is often a so-called amateurish work.

  Therefore, in the present invention, the user is allowed to perform only an operation for instructing image switching while listening to music output by reproducing audio data.

  That is, the editing of the moving image content according to the conventional technique is performed while the user visually confirms the time axis and the length of the content, as shown in FIG. That is, the data of the moving image content is edited by cutting and joining the data as if it were a film based on its length.

  On the other hand, in the present invention, as shown in FIG. 4, the moving image content is edited by switching images in accordance with the rhythm while the user listens to the music. In addition, the timing at which the image switching operation is performed is indicated by a diamond symbol in the drawing. In other words, according to the present invention, it is possible for the user to make editing while consciously perceiving the time axis without being aware of the visual time axis.

  By doing in this way, for example, when producing a promotion video of music, editing that switches images in synchronization with the progress of the music can be easily performed. You can also switch the image in synchronization with the time of percussion, such as cymbals, for parts of the song that are particularly uplifting. Even can be identified easily.

  Therefore, according to the present invention, anyone can easily perform advanced editing.

  Next, an example of editing operation processing by the content editing apparatus 10 will be described with reference to the flowchart of FIG.

  In step S21, the timer 27 starts measuring time.

  In step S <b> 22, the audio supply unit 22 starts supplying audio data designated in advance to the audio reproduction unit 25.

  In step S <b> 23, the material image supply unit 21 starts supplying the image data of the material images arranged in advance in the order of reproduction to the image reproduction unit 24.

  In step S24, the audio reproduction unit 25 reproduces the audio data supplied from the audio supply unit 22 by decoding it.

  In step S25, the image reproduction unit 24 reproduces the image data supplied from the material image supply unit 21 by decoding the image data.

  In step S <b> 26, it is determined whether or not the end of the editing operation process is commanded via the operation input unit 23.

  If it is determined in step S26 that the end of the editing operation process has not been instructed yet, the process proceeds to step S27.

  In step S27, the material image supply unit 21 determines whether or not switching of the material image is instructed via the operation input unit 23, and waits until it is determined that the switching is instructed.

  If it is determined in step S27 that switching has been commanded, the process proceeds to step S28. In step S28, the material image supply unit 21 switches the image data supplied to the image reproduction unit 24 to the image data of the next material image.

  In step S29, the operation recording unit 26 records the operation signal output from the operation input unit 23 determined to have been commanded in step S27 as operation information in association with the time measured by the timer 27.

  After the process of step S29, the process returns to step S25, and the subsequent processes are repeatedly executed.

  If it is determined in step S26 that the end of the editing operation process has been commanded, the editing operation process ends.

  In this way, the editing operation process is executed.

  Next, an example of content file generation processing will be described with reference to the flowchart of FIG.

  In step S <b> 41, the audio supply unit 22 starts supplying audio data to the audio reproduction unit 25.

  In step S <b> 42, the material image supply unit 21 sequentially supplies the image data of the material image to the image reproduction unit 24 based on the operation signal corresponding to the operation information output from the operation recording unit 26.

  In step S43, the audio reproduction unit 25 reproduces audio data.

  In step S44, the image reproduction unit 24 reproduces image data.

  When the content file generation process is executed, the image reproduced by the image reproduction unit 24 is not displayed on the display, and the sound reproduced by the audio reproduction unit 25 is not output from the speaker. When the content file generation process is executed, for example, the playback rate of the image playback unit 24 and the playback rate of the audio playback unit 25 are set to be twice the normal playback rate.

  In step S <b> 45, the capture processing unit 31 captures the data output from the image playback unit 24 and the data output from the audio playback unit 25.

  In step S46, the encoder 32 encodes the data captured in step S45 in a predetermined format (for example, a method such as MPEG or WMV). As a result, one content file composed of sound and images viewed by the user in the editing operation process is generated.

  In this way, the content file generation process is executed.
