Description

  The present invention relates to a technique for editing a moving image file recorded on a recording medium.

  In recent years, digital cameras and digital video cameras using a randomly accessible recording medium such as an optical disk, a hard disk drive, and a memory card have become widespread as apparatuses for recording / reproducing / editing images such as moving images and still images. In particular, a digital video camera can record a moving image for a long time, and a large-capacity memory card can shoot for several hours or more in one shooting.

  When recording is performed for such a long time, a scene recorded by one shooting may be divided into a plurality of files and recorded on the memory card due to limitations of the file system used in the memory card. For example, when a moving image is recorded on a 32 GB memory card using the FAT 32 file system, only 4 GB per file can be recorded due to file system limitations. When recording a moving image exceeding 4 GB, it is necessary to create and record a new file. For example, when recording is performed continuously for 30 minutes at an average recording rate of 24 Mbps, the total is about 5 GB, and two files of 4 GB + 1 GB are recorded.

  When editing a movie that has been divided into files and recorded, for example, if a cutout process that spans two files is executed, the movie file that has undergone scene editing is managed because two files exist on the recording medium. Work becomes complicated.

  In view of such circumstances, Patent Document 1 proposes a technique for combining relay recorded scenes in a relay recording function in which moving image recording is performed across a plurality of recording media for one scene.

JP 2005-174391 A

  However, in the above-mentioned Patent Document 1, when a part of a relay moving image recorded on one recording medium is deleted in a relay moving image recorded on a plurality of recording media, the recording capacity freed by the deletion is already increased. It is described that when a relay moving image recorded on one recording medium can be moved, it is moved and combined into one file. However, in the above-mentioned Patent Document 1, a moving image is divided into a plurality of recording media when the recording medium has insufficient free space and recording of the moving image is impossible. There is no description about dividing into files and recording, and in such a case, editing a moving image is not assumed.

  The present invention has been made in view of the above-described problems, and its purpose is to edit a series of videos composed of a plurality of files, combining them according to the edited videos, or complicated editing work. It is to realize a moving image editing technique capable of reducing operations and easily confirming an editing result.

  In order to solve the above problems and achieve the object, a video editing apparatus according to the present invention is a video editing apparatus that edits a series of videos divided into a plurality of files and recorded on a recording medium. A cutout unit that cuts out a part of the video, a designation unit that specifies a range in which the cutout unit cuts out a part of the series of videos, and a part of the video that constitutes the cutout range is recorded across a plurality of files. And combining means for combining and recording in one file according to the capacity or time of the partial moving image.

  According to the present invention, when a series of videos composed of a plurality of files is edited, the editing results can be easily combined by combining according to the edited videos or reducing complicated operations for editing. Can be confirmed.

The control unit 10 controls each unit by developing the program recorded in the ROM 17 on the RAM 14 and executing the program, and realizes processing in a flowchart described later. The control unit may be realized by a plurality of processors.

  The ROM 17 is a non-volatile storage medium that stores a program executed by the control unit 10. The RAM 14 is a volatile storage medium used as a work memory for the control unit 10. In addition, the RAM 14 performs compression processing and expansion processing on the image data generated by the image processing unit 13 and image data from the external recording medium 19 by the compression / decompression unit 11 or displays them on the display unit 15. Used as a VRAM (video memory) for temporary storage.

  An external recording medium 19 such as a memory card for recording image data is detachable from the video camera 100, and a recording medium I / F (interface) 18 that controls reading / writing of data with respect to the external recording medium 19 is provided. Have. The recording medium I / F 18 is a slot into which a recording medium such as a memory card can be mounted. FIG. 1 illustrates a state in which the external recording medium 19 is attached to the recording medium I / F 18, but it may be configured as an internal recording medium built in the video camera 100, or may be configured as an external recording medium and an internal recording medium. Both may be provided.

  The image processing unit 13 is a dedicated circuit for performing predetermined pixel interpolation, resizing processing, and color conversion processing on the image data captured by the imaging unit 12. Further, the image processing unit 13 performs a predetermined calculation process using the captured image data, and sends the calculation result to the control unit 10. Based on the calculation result obtained from the image processing unit 13, the control unit 10 performs various types of control (automatic exposure, auto white balance, etc.) regarding the imaging processing in the imaging unit 12.

  The compression / decompression unit 11 is a dedicated circuit for performing processing for compressing image data that has been subjected to image processing by the image processing unit 13 and processing for decompressing image data read from the external recording medium 19.

  The imaging unit 12 includes an image sensor including a zoom lens, a focus lens, an optical system including a diaphragm, and a semiconductor element such as a CMOS. Under the control of the control unit 10, a subject image is captured and an image signal of a moving image or a still image is captured. Is generated. A still image may be referred to as an image, and a moving image with sound may be referred to as a video.

  The display unit 15 is controlled by the control unit 10 to display / reproduce various setting states, images captured by the imaging unit 12 (including live view images), images read from an external recording medium, and the like. It is an EL display. The display unit 15 is used as a display in a view-type finder or a vari-angle LCD monitor.

  The operation unit 16 is a push button, a rotary dial, a slide switch, a touch panel, or the like that can be operated by the user. The operation unit 16 includes, for example, a power switch for turning on / off the video camera 100, a still image shooting button, a moving image recording start button, a mode switching button for switching the operation mode of the video camera 100 to a shooting mode, a playback mode, and the like. including. When the operation unit 16 includes a touch panel, the control unit 10 can detect the following operations on the touch panel. Touching the touch panel with a finger or pen (touch down). Touching the touch panel with a finger or pen (touch-on). Moving the touch panel while touching it with your finger or pen (move). The finger or pen that was touching the touch panel is released (touch-up). A state where nothing touches the touch panel (touch-off). The control unit 10 is notified of these operations and the position coordinates where the finger or pen touches the touch panel, and the control unit 10 determines what operation has been performed on the touch panel based on the notified information. . Regarding the move, the moving direction of the finger or pen moving on the touch panel can be determined for each vertical component / horizontal component on the touch panel based on the change of the position coordinates. It is also assumed that a stroke is drawn when touch-up is performed on the touch panel through a certain move from touch-down. The operation of drawing a stroke quickly is called a flick. A flick is an operation of quickly moving a certain distance while touching a finger on the touch panel and then releasing it, in other words, an operation of quickly tracing a finger on the touch panel. If it is detected that the moving is performed at a predetermined speed or more over a predetermined distance, and a touch-up is detected as it is, it can be determined that a flick has been performed. In addition, when it is detected that the movement is performed at a predetermined distance or more and less than a predetermined speed, it is determined that the drag has been performed. The touch panel may be any of various types of touch panels such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method. .

  In this example, the file system of the external recording medium 19 is described as FAT32 and DCF (Design rule for Camera File system) standard, and the moving image file format is MP4, but other formats may be applied.

  In this example, dedicated circuits are used for the compression / decompression unit 11 and the image processing unit 13, but a programmed general-purpose processor may be used. The functions of a plurality of blocks such as the control unit 10, the compression / decompression unit 11, and the image processing unit 13 may be realized by a single circuit or processor.

  <Movie Recording Process> Next, the movie recording process by the video camera 100 of the present embodiment will be described with reference to FIGS.

  FIG. 3 exemplifies the directory and file structure inside the external recording medium 19, the display position of the file, and the group ID.

  2 is realized by the control unit 10 of the video camera 100 developing the program stored in the ROM 17 on the RAM 14 and executing it. The same applies to FIGS. 6, 8, and 12 described later.

  When the video camera 100 is set to the camera mode (shooting mode) by an operation on the operation unit 16, the flow of FIG. 2 is started.

  In step S201, the control unit 10 starts the moving image recording process when the moving image recording start button of the operation unit 16 is pressed in the camera mode. When moving image recording is started, the image signal read from the imaging unit 12 is recorded on the external recording medium 19 via the image processing unit 13, the compression / decompression unit 11, the RAM 14, and the external recording medium I / F 18. . As shown in FIG. 3, the external recording medium 19 includes, for example, BBBB0001. The MP4 ((1) -1) file is recorded.

  In step S202, the control unit 10 determines whether or not the file size exceeds the upper limit value (maximum file size) of the file system, and BBBB0001. The file size of MP4 should not exceed 4 GB per file which is the upper limit value of the file system. As a result of the determination, if the threshold value of 4GB-α (α is an arbitrary value) is exceeded, the process proceeds to step S203. If the upper limit value is not exceeded, the moving image recording start button of the operation unit 16 is pressed again in step S206. Continue writing data to the file.

  In step S203, the control unit 10 stops writing data to the file.

  In step S204, the control unit 10 writes the group ID in the header of the file for which data writing has been stopped in step S203, and closes the file. This group ID is one of divided files when one continuous scene, that is, a scene in which a series of moving images are divided into a plurality of files (hereinafter referred to as file break scenes), and is a divided file constituting the same scene. This is information indicating that the file belongs to a group. It should be noted that the group ID may be arbitrary 4-byte data that does not overlap, and a random value or data stored in the ROM 17 may be incremented and used. The same value is added to files in the same group. In this example, BBBB0001. MP4 and BBBB0002. Since MP4 constitutes the same file break scene, both group IDs are set to 0x87654321. Then, 0x00000000 is added as a group ID to the other scenes that have been recorded without exceeding the above threshold.

  In step S205, the control unit 10 generates a new divided file and resumes data writing. Here, BBBB0001. As the next divided file of MP4, BBBB0002. MP4 is generated.

  In step S206, the control unit 10 determines whether or not the moving image recording start button of the operation unit 16 has been pressed again. If not, the control unit 10 returns to step S202 to continue writing data to the file. In this case, the process proceeds to step S207.

  In step S207, the control unit 10 performs a moving image recording stop process, writes the group ID in the file generated immediately before the stop, closes the file, and ends the present process.

  FIG. 4 shows an example of a scene list screen that accepts a user operation for playing back a file recorded on the external recording medium 19 on the display unit 15 or selecting it as an editing target for the video camera 100 of the present embodiment. doing.

  On the external recording medium 19, as shown in FIG. MP4 to BBBB0007. If MP4 is recorded, BBBB0001. MP4, BBBB0002. MP4 is a file break scene. When these files are laid out on the display unit 15 and displayed on the screen, BBBB0001. MP4 and BBBB0002. Since MP4 is a group of the same scene, it is displayed so as to overlap with the display position (1) in FIG. The image displayed at position (1) is BBBB0001., Which is the first file among (1) -1 and (1) -2. It is a thumbnail of MP4. The display may be changed as shown so that a plurality of files are grouped. Other BBBB0003. MP4 to BBBB0007. MP4 is displayed at BBBB0003.MP at display positions (2) to (6) in FIG. MP4 to BBBB0007. MP4 thumbnails are displayed.

  <Movie Editing Process> Next, a movie editing process by the video camera 100 of this embodiment will be described with reference to FIGS.

  FIG. 5 illustrates a touch panel type editing screen that can accept a user's touch operation for editing a file recorded on the external recording medium 19 with respect to the video camera 100 of the present embodiment.

  An editing screen 501 shown in FIG. 5A includes a scene display 502, a mark 503 for designating a cutout start point of a file, a mark 504 for designating a cutout end point, and an edit execution for cutting out a file in a specified range. Button 505 is included. The scene display 502 displays the entire scene to be edited selected in step S602 divided by the file size for each divided file. The marks 503 and 504 can be moved in the time direction of the scene display 502 by a drag operation on the editing screen 501, and the user can arbitrarily specify the cutout start point and cutout end point of the file.

  In FIG. 6, in step S <b> 601, the control unit 10 displays a scene list screen of files recorded on the external recording medium 19 on the display unit 15 as illustrated in FIG. 4.

  In steps S602 and S603, the control unit 10 selects an editing target scene in accordance with a scene selection operation by the user via the scene list screen, and displays the editing screen 501 in FIG.

  In step S604, the control unit 10 determines whether or not the scene selected in step S602 is a file break scene. If a file break scene is selected, the control unit 10 proceeds to step S605; The process proceeds to S606.

  In step S605, the control unit 10 displays the ratio of each divided file to the total file size. Specifically, the scene display 502 on the editing screen 501 is displayed with the file size for each divided file for the entire editing target scene being divided.

  In step S606, the control unit 10 determines the position of the mark 503 arbitrarily set by the user on the editing screen 501 as a file cutout start point. FIG. 5B illustrates an editing screen after the cutout start point is determined, and the left side of the cutout start point corresponds to a portion to be deleted after editing, and can be identified by a different color or the like It is possible to visually recognize that the portion is to be deleted after execution of editing.

  In step S <b> 607, the control unit 10 determines the position of the mark 504 arbitrarily set by the user on the edit screen 501 as the file cutout end point.

  In step S608, the control unit 10 determines whether or not the sum of the file sizes in the range between the cutout start point and the cutout end point is equal to or less than an upper limit (4GB-α) that is a predetermined threshold value. As a result of the determination, if the value is equal to or less than the threshold value, the process proceeds to step S609.

  In step S609, the control unit 10 determines that the file size after execution of editing is equal to or less than the upper limit value, and that each divided file can be combined. Therefore, as shown in FIG. Hide the delimiter.

  In step S610, since the file size after execution of the edit exceeds the upper limit value and it is impossible to combine the divided files, the control unit 10 does not combine the divided files in the scene display 502 as shown in FIG. Displays the file size separator for.

  In step S611, the control unit 10 determines whether or not the edit execution button 505 is pressed on the edit screen 501. If the button is pressed, the process proceeds to step S612. If not, the control unit 10 returns to step S606, and after step S606. Repeat the process.

  In step S612, the control unit 10 deletes a data portion other than the range between the cutout start point and the cutout end point. In the editing screen of FIG. 5C, the left side of the cutout start point and the right side of the cutout end point are deleted. Also, the scene to be edited is BBBB0001. MP4 and BBBB0002. If the file break scene includes MP4, the dividing process and the deleting process are executed for the two files recorded on the external recording medium 19 as shown in FIG.

  In step S613, the control unit 10 determines whether or not the sum of the file sizes cut out in step S612 is equal to or less than an upper limit (4GB-α) that is a predetermined threshold. As a result of the determination, if the value is equal to or less than the threshold value, the process proceeds to step S614.

  In step S614, the process of combining the files extracted in step S612 is executed. FIG. 7 shows an outline of file division processing, deletion processing, and combination in steps S612 to S614.

  In the editing process described above, when one scene is composed of one file, the processes in steps S605, S608 to S610, S613, and S614 are not executed. That is, on the editing screen of FIG. 5, the file size for each divided file is not displayed in the scene display 502 of FIG. 5, and the display when the edited files can be combined and the display when they are not combined are not performed. .

  As described above, according to the present embodiment, when editing a movie of a continuous scene composed of a plurality of files, the scene after editing is executed according to the upper limit value of the file size limited by the file system. When a plurality of files constituting the file can be combined, the combined file structure is displayed in an identifiable manner. As a result, it is possible to reduce troublesome operations for editing work and easily check the editing result.

  [Embodiment 2] Next, the moving picture recording process and the moving picture editing process of the second embodiment will be described.

  The amount of data that can be recorded per file is limited by the system factors of the video camera 100 in addition to the file system limitations described in the first embodiment. For example, since the capacity of the RAM 14 is small, recording may be performed only for one hour per file.

  In the present embodiment, a case where there is a limit on the amount of data that can be recorded per file other than the limit of the file system as in the first embodiment is considered.

  FIG. 8 is a flowchart showing moving image recording processing by the video camera 100 of the present embodiment. FIG. 9 illustrates the directory and file configuration inside the external recording medium 19, the display position of the file, and the group ID.

  The apparatus configuration of the present embodiment is the same as that of FIG. 1 described in the first embodiment. 8 are the same as steps S201 and S203 to S207 in FIG. 2, the description thereof will be omitted, and the description will focus on the differences.

  When the moving image recording process is started in step S801, the external recording medium 19 includes, for example, BBBB0004. MP4 ((3) -1) is recorded.

  In steps S802 and S803, the control unit 10 determines that BBBB0004. Writing of data to the file is continued until the MP4 recording time exceeds a time limit (for example, 1 hour), and writing of data to the file is stopped when the recording time exceeds.

  Thereafter, until the moving image recording start button of the operation unit 16 is pressed again, the file closing, the generation of new files (BBBB0005.MP4, BBBB0006.MP4) and the recording restart in steps S804 to S805 are repeatedly executed, and the process is performed. Complete.

  In the present embodiment, as shown in FIG. MP4 and BBBB0002. Since MP4 is a file break scene, the group ID is set to 0x00000001 for both files. Also, BBBB0004. MP4, BBBB0005. MP4, and BBBB0006. MP4 is BBBB0001. MP4 and BBBB0002. Since this is a file break scene different from MP4, the group ID is set to 0x00000002 for all three files. For other scene files (BBBB0003.MP4) recorded without exceeding one hour, 0x00000000 is added as a group ID.

  FIG. 10 illustrates an example of a scene list screen that accepts a user operation for playing back a file recorded on the external recording medium 19 on the display unit 15 or selecting it as an editing target for the video camera 100 of the present embodiment. doing.

  On the external recording medium 19, BBBB0001. MP4 to BBBB0007. When MP4 is recorded, BBBB0001. MP4 and BBBB0002. MP4 is a grouped file break scene. Also, BBBB0004. MP4 to BBBB0006. MP4 is also a grouped file break scene. When these files are laid out on the display unit 15 and displayed on the screen, BBBB0001. MP4 and BBBB0002. Since MP4 is a group of the same scene, it is displayed so as to overlap with the display position (1) in FIG. In addition, BBBB0004. MP4 to BBBB0006. Since MP4 is also a group of the same scene, it is displayed superimposed on the display position (3) in FIG. The image displayed at position (1) is BBBB0001., Which is the first file among (1) -1 and (1) -2. It is a thumbnail of MP4. The image displayed at the position (3) is BBBB0004. Which is the first file among (3) -1, (3) -2, and (3) -3. It is a thumbnail of MP4. The display may be changed as shown so that a plurality of images are grouped. Other BBBB0003. MP4 and BBBB0007. MP4 files are displayed at the display positions (2) and (4) in FIG. MP4 and BBBB0007. MP4 thumbnails are displayed.

  <Movie Editing Process> Next, the movie editing process by the video camera 100 of this embodiment will be described with reference to FIGS.

  FIG. 11 illustrates a touch panel type editing screen that can accept a user's touch operation for editing a file recorded on the external recording medium 19 with respect to the video camera 100 of the present embodiment.

  A scene display 1102, marks 1103 and 1104, and an edit execution button 1105 on the edit screen 1101 shown in FIG. 11A correspond to the scene display 502, marks 503 and 504, and the edit execution button 505 on the edit screen 501 in FIG.

  12 are the same as steps S601 to S606 and S608 to S612 in FIG. 6, description thereof will be omitted, and differences will be mainly described.

  In this embodiment, it is assumed that the file break scene of the image (3) is selected from the scene list screen of FIG. 10 in step S1202. In this case, in step S1205, the recording display 1102 of the editing screen 1101 in FIG. 11A displays the recording times of the three files divided according to the proportion of the entire scene.

  When the cutout start point and cutout end point of the file are determined in subsequent steps S1205 and S1206, the left side of the cutout start point and the right side of the cutout end point are different as shown in FIGS. 11 (b) and 11 (c). It is possible to visually recognize that it is a part to be deleted after execution of editing.

  In step S1208, the control unit 10 determines whether or not the total recording time of the file in the range between the cutout start point and the cutout end point is equal to or less than a predetermined time limit (1 hour). As a result of the determination, if it is less than or equal to the threshold value, the process proceeds to step S1209, and if not less than the threshold value, the process proceeds to step S1210.

  In step S1209, since the file size after execution of the edit is less than the time limit and the divided files can be combined, the recording time for each divided file in the scene display 1102 as shown in FIG. 5C. Hide the delimiter.

  In step S1210, the control unit 10 has a file size after execution of editing that exceeds a predetermined time limit, and cannot combine divided files. In this case, as shown in FIG. 11D, a point A at which a predetermined time limit has elapsed from the cut start point is displayed on the scene display 1102, and it can be visually confirmed that the file after editing is divided at this point A. To display.

  Thereafter, when the edit execution button 1105 is pressed in step S1211, the control unit 10 deletes a data portion other than the range between the cutout start point and the cutout end point in step S1212. In the editing screen of FIG. 11C, the left side of the cutout start point and the right side of the cutout end point are deleted. Also, the scene to be edited is BBBB0004. MP4 to BBBB0006. If the file break scene includes MP4, as shown in FIG. 13, BBBB0004. MP4 to BBBB0006. For MP4, file division processing and deletion processing are executed.

  In step S1213, when the total recording time of the files cut out in step S1212 is equal to or less than the time limit, the control unit 10 executes file combination processing in step S1214. On the other hand, if the total recording time of the file cut out in step S1212 exceeds the predetermined time limit, the file is divided at point A where the predetermined time limit (one hour) has elapsed from the cut start point in step S1215. Then, the process of combining the files before point A divided in step S1216 is executed.

  FIG. 13 shows an overview of the editing process in steps S1212 to S1215.

  In step S1212, the control unit 10 determines that the BBBB0004. MP4 to BBBB0006. A file division process and a deletion process are executed for MP4. By these processes, as shown in FIG. 13B, BBBB0004. The left side of the cut start point of MP4 and BBBB0006. A file with a total recording time of 1 hour and 45 minutes from which the right side is deleted from the cut end point of MP4 is generated.

  Further, the file cut out as shown in FIG. 13C is subdivided at a point A that is one hour from the cut start point, and BBBB0004. MP4 and BBBB0005. MP4 combining processing and BBBB0005.
