Description

  The present invention relates to a dubbing apparatus in which highlight scenes of moving images recorded on a dubbing source recording medium are dubbed to a dubbing destination recording medium so that a recording medium in which highlight scenes are collected can be easily created.

  Conventionally, there is a dubbing apparatus capable of dubbing data from one recording medium to another recording medium. Recently, a large-capacity hard disk drive is built in as a dubbing source recording medium so that a large amount of data to be dubbed can be stored, and an optical disc such as a DVD (Digital Versatile Disk) is used as a dubbing destination recording medium. Dubbing devices with an acceptable drive device have become commonplace.

  Such a dubbing apparatus usually includes a tuner so that a television broadcast program can be acquired as dubbing original data, and data held by an external device such as a digital video camera and other dubbing apparatus is also dubbing original data. An external connection terminal to which an external device can be connected is provided so that it can be used as data.

On the other hand, Patent Document 1 discloses a recording / reproducing apparatus in which only a highlight portion included in a television broadcast program recorded on a recording medium can be efficiently viewed. The recording / reproducing apparatus disclosed in Patent Document 1 detects the position of a swelled portion (highlight scene) in a program based on the image content or audio content of a program to be reproduced, and usually sets the preceding and following sections around the detected position. Playback is performed, and the other sections are fast-forwarded.
Japanese Patent Laid-Open No. 11-55613

  The conventional dubbing apparatus can edit the dubbing contents by a user's manual operation. For example, only a highlight scene is picked up from a recorded television broadcast program and dubbed to a DVD. It is also possible to create a DVD in which However, when dubbing only the highlight scene in this way, the user must confirm the contents of the recorded television broadcast program sequentially to identify the range corresponding to the highlight scene, and to perform the editing work of dubbing the identified range. Is required. Therefore, in order to dub only the highlight scene, there is a problem that the work and operation burden for editing are very large.

  On the other hand, since the recording / reproducing apparatus according to Patent Document 1 simply aims at efficiently viewing a highlight scene, it cannot perform dubbing of the highlight scene to another recording medium automatically. Therefore, even if the dubbing of the highlight scene is attempted using the recording / reproducing apparatus according to Patent Document 1, it is still necessary for the user to actively perform editing work, and other than the highlight scene is automatically fast-forwarded and reproduced. As a result, editing work becomes difficult, and there is a problem that the user is forced to view a fast-played video regardless of the user's will during editing.

  Further, in the recording / reproducing apparatus according to Patent Document 1, when a plurality of highlight scenes are detected, when the intervals between highlight scenes that are temporally forward and backward are short, the target ranges for normal reproduction that precede and follow are partially overlapped. In this case, since the overlapping portion is reproduced twice, the user's editing work is further hindered.

The present invention has been made in view of such problems, and performs special editing work by automatically detecting and dubbing highlight scenes in a moving image recorded on a recording medium as a dubbing source. Another object of the present invention is to provide a dubbing apparatus that can easily create a recording medium in which highlight scenes are collected.
In addition, the present invention also includes the process of reaching the highlight scene and after the highlight scene has elapsed when the recording medium collecting the highlight scene is reproduced by appropriately including the highlight scene before and after the highlight scene. It is an object of the present invention to provide a dubbing apparatus that allows a user to enjoy a reverberation and the like.
It is another object of the present invention to provide a dubbing apparatus that can automatically dub highlight scenes that move back and forth at short time intervals without overlapping.

  In order to solve the above problems, a dubbing apparatus according to the present invention is a dubbing apparatus comprising dubbing means for dubbing a moving image recorded on one recording medium to another recording medium, and a portion corresponding to a highlight included in the moving image. Means for receiving a highlight dubbing instruction for dubbing, a comparison means for comparing the content of a moving picture against a reference level when a highlight dubbing instruction is received, and a moving picture exceeding a reference level based on a comparison result of the comparing means Detection means for detecting a level-exceeding scene, and specifying means for specifying a range including the level-exceeding scene detected by the detection means as a dubbing portion, wherein the dubbing means includes the dubbing portion specified by the specifying means. It is characterized by dubbing.

  In the present invention, when the highlight dubbing instruction is received from the user, the level exceeding scene in the moving image exceeding the reference level is detected and the range including the detected level exceeding scene is dubbed. Even if it is not performed, portions corresponding to highlights can be automatically dubbed, and a recording medium in which highlight scenes are collected can be easily created. In addition, if the object which can be dubbed is the moving image recorded on the recording medium of dubbing origin, the moving image acquired from external apparatuses, such as a digital video camera, can also be included in dubbing object besides the program of a television broadcast.

  In addition, as a specific example of the process of comparing the content of the moving image with respect to the reference level, a change in an image constituting the moving image (a vector amount related to movement of an object included in the image, a background change) is defined in advance For example, comparison with a reference change level of an image and comparison of a level (sound level, sound peak spectrum, sound signal level, etc.) related to sound included in a moving image with a reference sound level. In particular, when comparing the sound level with the reference sound level, various sports programs and comedy programs that are closely related to changes in sound and highlight scenes will be dubbed without being affected by the image content of the video. It becomes easy to dub the light scene accurately.

In the dubbing apparatus according to the present invention, the specifying means includes a front range temporally forward from the over-level scene and / or a rear range temporally rearward from the over-level scene in the dubbing portion. It is characterized by.
In the present invention, since either or both of the front range and the rear range of the over-level scene are included in the dubbing portion, when the front range is included, the process leading to the over-level scene can be dubbed, and the rear range is included. In such a case, the content following the over-level scene can be dubbed, and the highlight scene can be reliably dubbed within an appropriate range.

  In the dubbing apparatus according to the present invention, the detection means includes means for detecting an end point scene in a range continuously exceeding a reference level from the level excess scene, and the specifying means includes the level excess scene to the end point scene. The dubbing portion includes a range of the above and a forward range that is temporally forward from the above-exceeding level scene and / or a backward range that is temporally backward from the end-point scene.

  In the present invention, since the range from the over-level scene to the end-point scene is included in the dubbing portion, it is possible to reliably dub highlight scenes that continue for a certain period of time, and the front range of the over-level scene and the back range of the end-point scene Since either or both of these are included in the dubbing portion, the peripheral contents of the highlight scene can be dubbed. That is, when the front range is included in the dubbing portion, when the dubbing content is reproduced, the user can confirm the process leading to the highlight scene and deepen the understanding of the highlight scene. In addition, when the rear range is included in the dubbed portion, when the dubbed content is reproduced, the user can check the content after the end point range has elapsed, and can enjoy the reverberation of the highlight scene.

  The dubbing apparatus according to the present invention detects whether or not dubbing portions that are temporally overlapped when the identifying means includes a front range and / or a rear range in a dubbing portion and identifies a plurality of dubbing portions. When the duplication detection means detects that the duplication detection means overlap, the dubbing means continues from the start point of the front dubbing part in time to the end point of the rear dubbing part in time. It is characterized by dubbing.

  In the present invention, when the dubbing portions that move back and forth in time overlap, dubbing is continuously performed twice from the start point of the front dubbing portion to the end point of the rear dubbing portion. Dubbing can be eliminated, and dubbing processing can be made more efficient by combining the dubbing portions that move back and forth at short intervals.

The dubbing apparatus according to the present invention is characterized by comprising a time receiving means for receiving the time in the front range and / or the rear range.
In the present invention, since either one or both of the front range and the rear range is received, the user can freely adjust the length of the range receiving the time. Therefore, it is possible to adjust the time before and after the user's preference, for example, adjusting the dubbing amount so that it does not become excessive, adjusting the range before and after the highlight scene, etc. Various dubbing parts can be adjusted.

  The dubbing apparatus according to the present invention comprises means for fast-forwarding and playing back a moving image at a speed faster than the recording speed on the recording medium when a highlight dubbing instruction is received, and the comparing means is a reference level for the fast-forwarded moving picture. And a means for changing the moving image reproduction speed to the recording speed when the dubbing means performs dubbing.

  In the present invention, since the moving image is played back at the fast-forwarding speed in comparison, the time required for dubbing can be shortened as compared with the case where the comparison process is performed on the moving image played at the normal playback speed. On the other hand, since dubbing is changed to a normal playback speed, deterioration of the dubbing content can be avoided, and even if the dubbing process is made efficient, the dubbing quality does not deteriorate. In addition, the dubbing part specifying process with comparison and detection and the dubbing process of the specified dubbing part may be performed collectively after first performing the specifying process from the beginning to the end of the moving image. The specific process and the dubbing process may be performed alternately.

  In the present invention, since the dubbing portion including the over-level scene is dubbed in response to the reception of the highlight dubbing instruction, the portion corresponding to the highlight can be automatically dubbed without any special editing work. A recording medium in which scenes are collected can be easily created.

In the present invention, since either or both of the front range and the rear range of the over-level scene are included in the dubbing portion, the range including the highlight scene can be reliably dubbed.
In the present invention, since the range from the over-level scene to the end-point scene is included in the dubbing portion, even if the highlight scene continues for a certain period of time, it can be reliably dubbed. Since either or both of the rear range and the both are included in the dubbing portion, the user can check at least one of the process leading to the highlight scene or the situation after the highlight scene has elapsed, and can further enjoy the highlight scene.

In the present invention, when the dubbing portions that move back and forth in time overlap, dubbing is repeated continuously from the start point of the front dubbing portion to the end point of the rear dubbing portion. It is possible to improve the efficiency of the dubbing process.
In the present invention, since either one or both of the front range and the rear range is received, the user can freely adjust the time length of the range in which the time is received.

  In the present invention, since the moving image is played back at fast forward for comparison, the processing time required for dubbing can be shortened, and the dubbing quality is deteriorated because the normal playback speed is changed during dubbing. There is no need to

  The DVD drive unit 8 accepts a DVD and reads or writes (records) data. The tray on which the received DVD is placed, a pickup that reads and writes data, a pickup drive unit, a DVD rotation drive unit, and the like Have Note that the DVD drive unit 8 of the present embodiment supports DVD-RW and DVD-R as data writable discs, and applies the VR format to DVD-RW as a format for writing data for dubbing. A video format is applied to the DVD-R.

  The highlight detection unit 9 detects a scene corresponding to the highlight included in the moving image data reproduced by the data processing unit 4, and the highlight detection unit 9 of the present embodiment reproduces the scene. Detect the highlight position based on the audio of the video.

  FIG. 2 is a graph showing the change of the audio level of the reproduced moving image with respect to the reproduction time, and the set reference audio level is indicated by a horizontal broken line. The highlight detection unit 9 compares the sound level of the moving image to be reproduced with the reference sound level, and at the time when the sound level is lower than the reference sound level or higher than the reference sound level (time t1, t3, t5 in FIG. 2). ) Is detected as an over-level scene, and the time corresponding to the end-point scene in a range continuously exceeding the reference level from the over-level scene (time t2, t4, t6 in FIG. 2) is detected. Note that the highlight detection unit 9 operates when the highlight dubbing button 30b is selected in the dubbing menu 30 shown in FIG. 3A and performs the above-described processing. To notify.

  1 is provided in the main body of the dubbing apparatus 1, and includes a plurality of keys such as an up / down / left / right key and a determination key, and each key is operated by a user to give an operation instruction. Accept and communicate to CPU 10. The remote control light receiving unit 12 connected to the CPU 10 receives signal light for remote operation from a remote control device 15 separate from the apparatus main body, and transmits the received content to the CPU 10. The remote controller 15 also includes a plurality of keys such as up / down / left / right keys and an enter key, and can accept an operation instruction from the user.

  The CPU 10 controls the operation status of each unit 2 to 9 based on the user's operation instruction received by the operation unit 11 or the remote control device 15, and incorporates the first memory 10a and the second memory 10b. In the first memory 10a, a program 20 defining the control processing contents of the CPU 10a and a menu image 21 for OSD (On Screen Display) corresponding to various menus shown in FIGS. 3A and 3B are recorded and set in advance. The reference audio level value to be recorded is also recorded. In addition, data and files associated with the processing are temporarily recorded in the second memory 10b.

  Of course, the program 20 recorded in the first memory 10a also defines the dubbing process among the many processes performed by the CPU 10a, and details of the process performed by the CPU 10 in the dubbing of the highlight scene will be described in detail below.

  When activated, the dubbing apparatus 1 displays a start menu (not shown) listing selectable processing items such as a recording list, dubbing, erasure, and reservation on an external television device. When dubbing is selected by the user, the CPU 10 performs a control process for displaying the dubbing menu 30 shown in FIG. 3A on the television device.

  The dubbing menu 30 includes a normal dubbing button 30a and a highlight dubbing button 30b. When the normal dubbing button 30a is selected by a user operation, selection of a dubbing source and a dubbing destination, and selection of a dubbing target, A menu for selecting the dubbing image quality and the like is sequentially displayed on the television device, and a general dubbing process is performed based on the contents selected by the user.

  On the other hand, when the highlight dubbing button 30b is selected in the dubbing menu 30, the CPU 10 accepts the highlight dubbing instruction, and the highlight dubbing setting menu 31 shown in FIG. 3B is displayed on the television device. Perform the process. The highlight dubbing setting menu 31 includes a reference audio level adjustment field 31a, a front range adjustment field 31b, a rear range adjustment field 31c, an OK button 31d, and a cancel button 31e.

  The forward range to be adjusted in the forward range adjustment column 31b means a range corresponding to the time X1 ahead in the time advance direction from the times t1, t3, and t5 corresponding to the level excess scene in the graph shown in FIG. In the forward range adjustment field 31b, the value of the time X1 desired by the user can be received. Similarly, the backward range to be adjusted in the backward range adjustment column 31c means a range corresponding to the time X2 behind the time t2, t4 and t6 corresponding to the end point scene in the graph of FIG. Then, the value of the time X2 desired by the user is received in the rear range adjustment column 31c.

  The values received in the front range adjustment field 31b and the rear range adjustment field 31c are set as values for time X1 and time X2, respectively. The time X1 and the time X2 are set to 30 seconds by default, but can be set to 0 seconds. The reference audio level adjustment field 31a is set to standard in a default state, and the reference audio level can be appropriately increased or decreased by a user operation.

  When the OK button 31d is selected by the user after setting the adjustment fields 31a to 31c, the set content is written in the first memory 10a of the CPU 10 and proceeds to the next stage. On the other hand, when the cancel button 31e is selected by the user, the contents set in each of the adjustment fields 31a to 31c are not written to the first memory 10a, and the process proceeds to the next stage.

  After the setting in the highlight dubbing setting menu 31, the menu for selecting the dubbing source and dubbing destination, selecting the dubbing target, selecting the dubbing image quality, etc. is sequentially applied to the television device in the same manner as in the case of general dubbing. Then, the highlight scene dubbing process is started based on the contents selected by the user. In the highlight scene dubbing process, the CPU 10 first reproduces the dubbing source data (moving image) from the beginning to the end, and based on the detection result of the highlight detection unit 9, the dubbing portion (to the highlight scene including the over-level scene). The control part 6 performs dubbing using the control unit 6.

  At this time, in order to shorten the processing time required for specifying the dubbing portion, the CPU 10 has a normal speed (recording speed) when the dubbing source data is recorded within the reproduction speed at which the highlight detection unit 9 can perform the comparison detection process. ) The control unit 6 performs control so that dubbing target data (moving image) is played back at a higher speed. Note that when the dubbing portion is dubbed, the normal playback speed is changed.

  The processing relating to the specific dubbing part specification is performed by the CPU 10 based on the comparison detection result by the highlight detection unit 9 and the contents set in the highlight dubbing setting menu 31 described above. For example, in the case shown in FIG. 2, the highlight detection unit 9 notifies the CPU 10 of the detected time t1 of the over-level scene and the time t2 of the end-point scene with respect to the audio level of the fast-played moving image. A range sandwiched between time T10 (start point of the dubbing part) returned from time T1 (start point of the dubbing part) and time T11 (end point of dubbing part) advanced backward from time t2 by time X2 is specified as the dubbing part, The position of the specified dubbing portion according to the times T10 and T11 is recorded in the second memory 10b.

  Thereafter, the CPU 10 specifies the dubbing portion in the same manner. In addition, when a plurality of dubbing portions are specified, the CPU 10 detects whether or not the dubbing portions that move back and forth in time overlap. Specifically, when the CPU 10 determines whether or not the interval between the time of the end point scene of the front dubbing portion and the time of the rear level excess scene is less than the total time of the time X1 and the time X2, and is less than the total time Performs the process of combining the previous and next dubbed parts.

  For example, in FIG. 2, the time interval (t5-t4) between the time t4 of the second end scene and the time t5 of the third over-level scene, and the total time (X2 + X1) of the time X2 and the time X1 are represented by the CPU 10. Compare. In the case of FIG. 2, the CPU 10 determines that the time interval (t5−t4) is equal to or less than the total time (X2 + X1). In this case, the CPU 10 records, in the second memory 10b, the recording position at time T14 advanced backward by time X2 from time t6 corresponding to the third end scene, not at time T13 advanced backward by time X2 from time t4. Then, a range from time T12 (start point of the dubbing portion) to time T14 (end point of the dubbing portion) is continuously set as a dubbing target. When the interval between the detection scenes that move back and forth in this way is short, the dubbing apparatus 1 prevents the different dubbing parts from including overlapping scenes by combining them into one dubbing part, and the adjacent dubbing parts. Is prevented from being shredded, and the number of dubbing portions is reduced to improve the efficiency of the dubbing process.

  The CPU 10 performs the dubbing process after performing the above-described dubbing part specifying process to the end of the moving image. In this dubbing process, only the dubbing portion sandwiched between the start point (time T10, T12) and the end point (time T11, T14) recorded in the second memory 10b is sequentially read from the dubbing source and recorded in the dubbing destination. . Note that the storage medium (hard disk device 7 and DVD) used in the present embodiment can be randomly accessed, so even when the dubbing process is partially performed as described above, the dubbed portion is quickly read and dubbed. Can process.

  The first flowchart shown in FIG. 4 is an arrangement of the dubbing processing procedure of the dubbing apparatus 1 based on the control of the CPU 10 described above. The flow of the dubbing process will be described below according to the first flowchart. The following description corresponds to the case where the dubbing source recording medium is set in the hard disk device 7 and the dubbing destination recording medium is set to DVD to create a DVD in which highlight scenes are collected. It is assumed that dubbing target data (moving image) 22 acquired by the tuner unit 2 or the external device connection unit 3 has already been recorded in the hard disk device 7.

  First, when the dubbing process is started, the dubbing apparatus 1 displays a dubbing menu 30 shown in FIG. 3A, and determines whether the highlight dubbing button 30b is selected and a highlight dubbing instruction is received from the user ( S1). When the highlight dubbing instruction is not received (S1: NO), it is determined whether or not the normal dubbing instruction is received (S2). When the normal dubbing instruction is received (S2: YES), the normal dubbing process is performed. (S3), the process ends. If the normal dubbing instruction has not been received (S2: NO), the process returns to the highlight dubbing instruction reception determination step (S1).

  When a highlight dubbing instruction is accepted (S1: YES), the highlight dubbing setting menu 31 shown in FIG. 3B is displayed and various settings are made, a dubbing source and a dubbing destination are set, a dubbing target video is selected, and the like. (S4), the fast-forward playback of the moving image recorded on the dubbing source hard disk device 7 is continued from the first scene to the last scene (S5). In this fast-forward playback process, the CPU 10 performs a detection process of a part corresponding to the comparison and highlight scene to identify a dubbing part (S6). When fast-forward playback is completed up to the last scene of the moving image, a highlight dubbing process is performed in which only the specified dubbed part is recorded on the dubbing destination DVD (S7).

  The second flowchart shown in FIG. 5 shows the detailed processing flow of specifying the dubbing part (S6) in the first flowchart of FIG. Specifically, when the dubbing unit 1 starts the dubbing unit specifying process, the dubbing apparatus 1 compares and determines whether or not the sound level of the scene of the moving image that is played back in fast-forward is equal to or higher than the reference sound level (S10). If it is determined that the playback scene is equal to or higher than the reference audio level (S10: YES), the CPU 10 determines whether or not the playback scene is the first level-exceeded scene that exceeds the reference audio level (S11). If it is determined that the playback scene is the first level-exceeded scene (S11: YES), the dubbing apparatus 1 advances the process to the previous stage (S13).

  If it is determined that the playback scene is not the first level-exceeded scene, that is, the second or subsequent level-exceeded scene (S11: NO), the playback scene exceeding the reference audio level (level-exceeded scene) It is determined whether or not the total time of the time X1 in the front range and the time X2 in the rear range related to the previously detected end point scene is equal to or greater than the time interval from the previous end point scene to the current level excess scene ( S12). When the total time is not equal to or greater than the time interval (S12: NO), the start time of the front range (for example, time T12 in FIG. 2) is recorded in the second memory 10b of the CPU 10 as the start point of the dubbing portion (S13), and the dubbing unit Specify the starting point of.

  After recording of the start point of the dubbing part (S13) or when the total time is equal to or greater than the time interval (S12: YES), the dubbing device 1 has the audio level of the video scene that is continuously fast-forwarded and reproduced below the reference audio level. It is determined whether or not (S14). If the audio level of the playback scene is not less than or equal to the reference audio level (S14: NO), fast-forward playback is continued, and it is determined whether or not the audio level is below the reference audio level. When the audio level of the playback scene is equal to or lower than the reference audio level (S14: YES), an end point corresponding to the end time of the rear range X2 behind the playback scene (end scene) is stored in the second memory 10b. Recording is performed (S15), and the end point of the dubbing unit is specified.

  After the recording of the end point (S15) or when the audio level of the playback scene is not equal to or higher than the reference audio level (S10: NO), the dubbing apparatus 1 determines whether or not the moving image has been played back to the end (S16), and finally If it has not been reproduced (S16: NO), the reproduction is continued and the process returns to the step of determining whether or not the audio level of the reproduction scene is equal to or higher than the reference audio level (S10). If the moving image has been reproduced to the end (S16: YES), the dubbing part specifying process is terminated.

  By performing such a dubbing part specifying process, points indicating the range of the specified dubbing part (time T10, T12 according to the start point and time T11, T14 according to the end point shown in FIG. 2) are the first. 4 is recorded sequentially in the memory 10b, so in the highlight dubbing process (S7) in the first flowchart of FIG. 4, it is recorded in the dubbing source hard disk device 7 with the point recorded in the second memory 10b as a mark. Dubb the dubbed part of the movie to DVD. As a result, it is possible to easily create a DVD in which highlight scenes are collected without the user performing special editing work. Moreover, since the created DVD includes the range before and after the highlight scene, when this DVD is played, in addition to the process of reaching the highlight scene, you can also check the afterglow after the highlight scene. Compared to the case where only light scenes are collected, the user can enjoy highlight scenes more.

  In addition, the range before and after the highlight scene can be adjusted with the highlight dubbing setting menu 31 shown in FIG. 3B, so that it can be adjusted according to the user's preference. You can easily create a DVD with the same contents.

  In addition, the dubbing apparatus 1 which concerns on this invention is not limited to the form mentioned above, A various modification example is applicable. For example, as a dubbing source and a dubbing destination recording medium, in addition to a hard disk device and a DVD, an optical disc such as a BD or HD DVD, or a semiconductor memory can be applied. In this case, a read / write unit corresponding to them is provided in the dubbing device 1. Will be provided.

  Furthermore, in order to simplify the process related to the setting of the dubbing portion, either the front range adjustment field 31b or the rear range adjustment field 31c is omitted in the highlight dubbing setting menu 31 in FIG. Only one of the front range and the rear range may be included in the dubbing portion. Furthermore, the detection of the part corresponding to the highlight scene is performed not only by comparing the audio level of the video with the reference audio level, but also the video content of the video (for example, the motion vector amount of the object in the video, the background motion vector). It is also possible to carry out based on a comparison result between a reference video level (for example, a reference motion vector amount) and the like.

  Further, in the processing procedure of the first flowchart shown in FIG. 4, the moving image is first detected from the beginning to the end, the dubbing portion is specified, and then the highlight dubbing processing is collectively performed. When one dubbing part is specified from the above, the dubbing part specifying process and the dubbing process may be alternately performed so that the specified dubbing part is dubbed. In this case, the playback speed of fast-forward playback to identify the dubbing part is changed to the normal speed (recording speed) at the time of dubbing. When dubbing is finished, the playback speed is returned to fast-forward playback, and the playback speed of the movie to be dubbed Control is performed to alternately change.

  Furthermore, in order to simplify the dubbing part specifying process, it is possible to omit the process of detecting the end point scene (the scene corresponding to times t2, t4, and t6 in the graph of FIG. 2). In this case, as shown in the graph of FIG. 6A, when the dubbing apparatus 1 detects an over-level scene (a scene corresponding to times t20, t21, and t22 in the figure), the detected over-level scene is Whether or not to continue for a set time A (for example, 10 seconds) or longer is detected by a timer function provided in the CPU 10. If the over-level scene is equal to or greater than time A, the front range in time (range of time X10) from the start time (t20, t21, t22) of the over-level scene, and the rear range in time behind (time) The portion including X20 range) is specified as the dubbing portion.

  Even when the dubbing portion is specified as described above, when the dubbing portions that move back and forth in time overlap, a process of combining the dubbing portions that move back and forth into one continuous dubbing portion is performed. For example, in the graph of FIG. 6A, when the rear range (time X20) of the over-level scene at time t22 overlaps with the front range (time X10) of the over-level scene at time t23 (from time t22 to time t23). The time interval until the time interval is equal to or less than the total time of the time X20 and the time X10), a dubbing portion from the start point (time T34) of the front range at time t22 to the end point (time T36) of the rear range at time t23 As specified.

  Then, the start point (time T30, T32, T34) and end point (time T31, T33, T36) of each identified dubbing part are recorded in the second memory 10b of the CPU 10, and the highlight dubbing process is performed based on the recorded point. I do. As described above, when the highlight dubbing process is performed with the pattern shown in the graph of FIG. 6A, the dubbing can be efficiently performed when the moving image to be dubbed includes a highlight scene in a divided manner.

  The overall dubbing process flow for identifying the dubbing part shown in the graph of FIG. 6A is performed by first identifying all the dubbing parts as shown in the first flowchart of FIG. Further, dubbing processing may be performed every time one dubbing portion is specified. In the latter case, as shown in FIG. 6B, fast-forward playback for specifying the dubbed portion and normal playback for dubbing the specified dubbed portion are repeated.

  In addition, in the case where the dubbed portion is specified by any of the patterns shown in the graph of FIG. 2 and the graph of FIG. Of course, it is also possible to specify the dubbing portion by reproducing the moving image at a normal reproduction speed (recording speed).

It is a block diagram which shows the main internal structures of the dubbing apparatus which concerns on embodiment of this invention.
