Description

[Technical Field]

[0001] The present invention relates to an editing device for editing additional information files associated with moving image files. [Background technology]

[0002] In recent years, broadcasting stations, news agencies, and other news sites have been seeking to streamline their video editing workflows in order to quickly and accurately convey information via social networking services (SNS). To achieve this, efforts have been made to utilize additional information files, which record additional information such as the interview title and location during filming. These additional information files are used to quickly search for desired video files from among the large number of video files stored on a server, based on additional information such as the interview title. They are also used to accurately create captions based on additional information such as the interview location. By utilizing additional information files in this way, more accurate and timely reporting can be achieved.

[0003] Additional information can be set by entering text into the video camera before shooting a video, and once shooting begins, it will be recorded as an additional information file along with the video file. Additional information can also be set for the next video to be shot by sending it from an external device such as a smartphone to the video camera, and once shooting begins, it will be recorded as an additional information file along with the video file. Additional information files already recorded in the video camera can also be edited by operating the video camera or an external device such as a smartphone.

[0004] Patent Document 1 describes that the user can select which of the following content to associate with the additional information when editing: the content that was recorded immediately before recording, the content that is about to be recorded, or the content that is currently being recorded. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-98658 Summary of the Invention [Problem to be solved by the invention]

[0006] If a problem such as a power outage occurs while recording a video, the video file and additional information files may be damaged. Therefore, video cameras have a function to repair damaged parts of the video file and additional information files. Normally, if a video file needs to be repaired, you cannot edit it until you perform the repair process.

[0007] Therefore, if a video file or an additional information file attached to a video file is damaged and needs to be restored, it may be possible to confuse the user if the additional information file can be edited. Also, if a video file or an additional information file is damaged and needs to be restored, editing the additional information file before the file is restored may make it impossible to restore the restored portion.

[0008] The present invention has been made in consideration of such circumstances, and aims to provide an editing device that can perform editing processing of additional information files depending on whether the video file or additional information file needs to be repaired. [Means for solving the problem]

[0009] In order to achieve the above object, an editing device of the present invention comprises: The system includes an editing means for editing an additional information file related to a video file, and a control means for controlling not to allow editing of the additional information file when the additional information file is a file that requires repair processing or when a video file related to the additional information file is a file that requires repair processing, and the control means is characterized in that even if the video file requires repair processing, it allows editing of the additional information file if the recording length of the video data of the video file is equal to or greater than a predetermined recording length and the additional information file does not require repair processing. Alternatively, the editing device of the present invention comprises: The system includes an editing means for editing an additional information file related to a moving image file, and a control means for controlling not to allow editing of the additional information file when the additional information file is a file that requires repair processing, or when a moving image file related to the additional information file is a file that requires repair processing, and the control means controls not to allow editing of the additional information file when the moving image file requires repair processing and the recording length of the moving image data of the moving image file is less than a predetermined recording length, regardless of whether the additional information file requires repair processing or not. Alternatively, the editing device of the present invention comprises: The system includes an editing means for editing an additional information file related to a video file, and a control means for controlling not to allow editing of the additional information file when the additional information file is a file that requires repair processing, or when a video file related to the additional information file is a file that requires repair processing, and the control means is characterized in that even if the additional information file requires repair processing, it allows editing of some additional information items of the additional information file if certain conditions are met. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an editing device that can execute editing processing of an additional information file depending on whether a moving image file or an additional information file needs to be restored. [Brief explanation of the drawings]

[0011] [Figure 1] Block diagram of editing device [Figure 2] Flowchart of editing process in the first embodiment [Figure 3] Flowchart of editing process in the second embodiment DETAILED DESCRIPTION OF THE INVENTION

[0012] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0013] <Editing equipment configuration> FIG. 1 is a block diagram showing an example of the internal configuration of an editing device 100 according to this embodiment. The editing device 100 is capable of accessing a recording medium on which a video file and an additional information file are recorded and repairing or editing the video file and the additional information file. The present invention may also be applied to an imaging device such as a video camera that has a shooting unit for shooting video and records the video file and the additional information file on a recording medium. The additional information file records additional information for the video file. The additional information file records additional information, including not only additional information determined when the video file is recorded but also additional information set by the user, as an XML file (Extensible MarkUp Language file). The additional information file may be recorded in a format such as NewsML-G2, standardized by the IPTC (International Press Telecommunications Council). If the editing device 100 is an imaging device including an imaging unit, the editing device 100 has the function of recording video data captured by the imaging unit as a video file on a recording medium 105 and recording an additional information file containing additional information for the recorded video file on the recording medium.

[0014] As shown in Fig. 1, the editing device 100 includes a bus 101, a CPU (control unit) 102, a ROM 103, a RAM 104, a recording medium 105, a recording control unit 106, an associated file determination unit 107, a video file repair determination unit 108, an additional information file repair determination unit 109, an additional information file editing unit 110, a file repair unit 111, a communication unit 112, an operation unit 113, and a display unit 114. In Fig. 1, the CPU 102, the recording control unit 106, the associated file determination unit 107, the video file repair determination unit 108, the additional information file repair determination unit 109, the additional information file editing unit 110, and the file repair unit 111 are configured separately. However, these functions may be provided in the CPU 102. Furthermore, these functions may be realized by multiple processors rather than by a single CPU.

[0015] The bus 101 is made up of an address bus, a data bus, and a control bus, and is used to communicate commands and data between the components of the editing device 100.

[0016] The CPU (control unit) 102 is a processor that reads out programs stored in the ROM 103, executes the programs, performs various arithmetic processing, and controls each component of the editing device 100. Note that the flowcharts described below are realized by the CPU 102 executing the programs read out from the ROM 103 and controlling the various arithmetic processing and each component.

[0017] The ROM 103 is a non-volatile memory that stores programs, various setting information, etc. The RAM 104 is a volatile memory that is used as a work memory.

[0018] The recording medium 105 is a removable recording medium such as an SD card, and is inserted into the editing device 100 to record moving image files and additional information files related to the moving image files.

[0019] The recording control unit 106 is a control unit for writing and reading data to and from the recording medium 105. Upon receiving a read command from the CPU 102, the recording control unit 106 sequentially reads a specified area of ​​the recording medium 105 in fixed-size increments, expands the data in RAM 104, and buffers it. Furthermore, upon receiving a write command from the CPU 102, the recording control unit 106 receives data to be written that has been expanded in RAM 104, and sequentially writes the received data in fixed-size increments to the recording medium 105. Next, upon completion of the read or write, the recording control unit 106 notifies the CPU 102 of this fact. The function of the recording control unit 106 may be provided to the CPU 102.

[0020] The related file determination unit 107 identifies additional information files related to a video file or video files related to an additional information file from the file name of each file. For example, it searches for an additional information file name that matches the video file name excluding the extension, or searches for a video file name that matches the additional information file name. If a matching file name is found, it determines that the video file and additional information file with the matching file name are related to each other.

[0021] The video file repair determination unit 108 determines whether a video file is a repair-required file based on the video file extension, etc. For example, in the case of an MP4 format video file, the extension is recorded as "DMV" while the video file is being recorded, and then the extension is changed to "MP4" and recorded once the recording is complete. A video file whose recording is not completed normally, for example due to a momentary power outage while the video file is being recorded, will retain the DMV extension. In other words, the video file repair determination unit 108 determines that a video file with the DMV extension is a video file that needs to be repaired. The determination method is not limited to this, and other information may also be used for the determination.

[0022] The additional information file repair determination unit 109 determines whether the additional information file is a file that requires repair processing based on the extension of the additional information file, etc. While the additional information file is being recorded, the extension of the additional information file is recorded as "DAT," and when recording is completed, the extension is changed to XML and recorded. Therefore, the extension of an additional information file that has not been properly recorded due to a momentary power outage remains DAT. Therefore, the additional information file repair determination unit 109 determines that an additional information file with the extension DAT is an additional information file that requires repair. The determination method is not limited to this, and other information may be used for the determination.

[0023] When an editing instruction is received through an operation on the operation unit 113 of the editing device, or when an editing request is received from an external device such as a smartphone, the additional information file editing unit 110 updates the additional information file and records it on the recording medium 105. For example, when an instruction to edit additional information regarding a news coverage title or news coverage location is received, an additional information file is generated in which the additional information regarding the news coverage title or news coverage location for which editing was requested has been changed, and the file is overwritten and recorded on the recording medium 105 (the file before editing is deleted and the generated file is recorded).

[0024] The file repair unit 111 executes repair processing for video files and additional information files that require editing. When a file repair instruction is input from the operation unit 113 or an external device, the file repair unit 111 reads the file that is the target of repair processing from the recording medium 105 and executes the repair processing.

[0025] The communication unit 112 is a communication unit for wireless communication with external devices such as smartphones, and receives various data, requests, instructions, etc. from the external devices and transmits various data, requests, instructions, etc. to the external devices under the control of the control unit 102. A request to edit an additional information file from an external device is received by the communication unit.

[0026] The operation unit 113 is an operation unit that accepts operations from the user. If the operation unit 113 includes a touch panel, the control unit 102 can detect the following operations on the touch panel. The operation unit 113 notifies the control unit 102 that it has accepted an operation from the user, and the control unit 102 performs control to execute processing according to the accepted operation.

[0027] The display unit 114 is a display unit that displays images recorded on the recording medium 105, various setting screens, etc. Display data generated by the control unit 102 and stored in the RAM 104 is displayed on the display unit 114 under the display control of the control unit 102, thereby realizing display on the display unit 114.

[0028] First Embodiment The editing process of the additional information file in the editing device 100 of this embodiment will be described with reference to FIG.

[0029] First, in S200, control unit 102 determines whether or not communication unit 112 has received an edit request (edit instruction) for an additional information file from an external device.

[0030] In S201, the control unit 102 causes the related file determination unit 107 to determine, from among the video files recorded on the recording medium 105, which video files are related to the additional information file specified as the target for editing in the editing request. If there is a video file related to the additional information file for which editing was requested, the process transitions to S202, and if there is no related video file, the process transitions to S206. In S202, the control unit 102 causes the video file repair determination unit 108 to determine whether the video file determined in S201 is a target for repair. The video file repair determination unit 108 determines that the video file is a target for repair if the video file extension is DMV, which means that the file is being recorded. If it is determined that the video file is a target for repair, the process transitions to S206, and if it is determined that the video file is not a target for repair, the process transitions to S203.

[0031] In S203, the control unit 102 determines whether the additional information file for which editing has been requested is a file that needs to be repaired by using the additional information file repair determination unit 109. If the extension of the additional information file is DAT, which means that the file is being recorded, the additional information file repair determination unit 109 determines that the file needs to be repaired. Not If it is determined that the error is a repair target, the process proceeds to S204, and if it is determined that the error is a repair target, the process proceeds to S206.

[0032] In S204, the control unit 102 permits editing of the additional information file for which editing has been requested, and notifies the external device via the communication unit 112 that editing has been permitted. Then, in S205, the control unit 102 causes the additional information file editing unit 110 to execute editing processing of the additional information file in response to the editing request. The additional information file editing unit 110 reads the additional information file to be edited in response to the editing request from the recording medium 105, edits the additional information in response to the editing request, generates an edited additional information file, and records it on the recording medium 105. When the editing processing is complete, the control unit 102 notifies the external device via the communication unit 112 that the editing processing has been executed.

[0033] In S206, the control unit 102 prohibits editing of the additional information file for which editing has been requested, and notifies the external device via the communication unit 112 that editing of the additional information file for which editing has been requested is not possible.

[0034] The external device, which has been notified by the editing device whether editing is permitted or not, may display whether editing of the additional information file for which editing is requested is permitted or not, and notify the user.

[0035] In the above description, it is assumed that the editing permission of the additional information file for which an editing request has been made (specified as the editing target) is determined. However, it is also possible to determine whether or not editing is possible in the editing device for additional information files that can be the editing target, rather than the additional information file for which an editing request has been made, and notify the external device of the result. For example, the editing device determines whether or not editing is possible for an additional information file related to a video file being displayed on an external device, and notifies the external device of the result. image It is also possible to display whether the additional information can be edited together with the file. Since it is not possible to determine from an external device whether a video file or additional information file is to be repaired, by displaying whether the additional information file can be edited in this way, the user can grasp which additional information files can be edited.

[0036] As described above, in this embodiment, if there is no video file associated with the additional information file, or if at least one of the video file and the additional information file is subject to repair, editing of the additional information file is not permitted. Then, if the additional information file is not subject to repair and the video file is not subject to repair, editing is permitted. Whether or not the additional information file can be edited is determined depending on whether the video file or the additional information file is subject to repair, which prevents user confusion. Furthermore, if the video file or the additional information file is subject to repair, editing of the additional information file is prohibited, which prevents the additional information file from becoming unrepairable.

[0037] In the above description, an editing request (editing instruction) is received from an external device. However, an editing request may be received from the operation unit 113 of the editing device through a user operation, and the control unit 102 may determine whether or not editing is possible for the additional information file that is the subject of editing in the editing request. In this case, the determination result may be displayed on the display unit 114 together with the video file. In the above description, a case has been described in which the editing device determines whether or not editing is possible for the additional information file. However, when the present invention is realized in an editing system including the editing device and an external device, the editing device may determine whether or not editing is possible for the additional information file, or the external device may perform a process for determining whether or not editing is possible for the additional information file, as shown in the flowchart of FIG. 2. The determination result of whether or not editing is possible may be displayed on the display unit 114 of the editing device, or on the display unit of the external device.

[0038] <Second embodiment> The second embodiment has the same configuration of the editing device 100 as the first embodiment.

[0039] The flow of the editing process of the additional information file will be described using Figure 3. The same processes as those in the first embodiment are assigned the same numbers as those in Figure 2 of the first embodiment, and the description will be omitted. Note that the other embodiments described in the first embodiment may also be applied to the second embodiment.

[0040] First, in S200, the control unit 102 determines whether an edit request for an additional information file has been received from an external device. When an edit request for an additional information file has been received, in S201 the video file repair determination unit 108 identifies a video file related to the additional information file that is the subject of the edit request. If the video file is identified, the process proceeds to S202, and if not, the process proceeds to S206. In S202, the video file repair determination unit 108 determines whether the video file determined in S201 is a file that needs to be repaired. If it is determined that it is a file that needs to be repaired, the process proceeds to S301, and if it is determined that it is not a file that needs to be repaired, the process proceeds to S203. In S203, the additional information file repair determination unit 109 determines whether the additional information file for which an edit request has been made is a file that needs to be repaired. If it is determined that it is a file that needs to be repaired, the process proceeds to S30 4 If it is determined that the file does not need to be repaired, the process proceeds to S204. In S204, the control unit 102 permits editing of the additional information file for which an edit request has been made, and notifies the external device via the communication unit 112 that editing has been permitted. Note that in S204, editing is permitted for all additional information items (that can be specified as items to be edited) of the additional information file. Then, in S205, the control unit 102 causes the additional information file editing unit 110 to execute editing processing for the additional information file in accordance with the edit request. In S206, the control unit 102 does not permit or prohibit editing of the additional information file for which an edit request has been made, and notifies the external device via the communication unit 112 that editing has been prohibited.

[0041] In S301, the control unit 102 determines whether the recording length (number of frames, etc.) of the video data of a video file determined to need to be restored is a predetermined recording length. In this embodiment, the control unit 102 determines whether the video data is recorded for 1 GOP or more. This is because, when a video file that needs to be restored is restored by the file restoration unit 111, if the recording length is less than 1 GOP, the video data will be deleted without being restored. If it is determined that the recording length is greater than or equal to the predetermined recording length, the process proceeds to S302, and if it is determined that the recording length is less than the predetermined recording length, the process proceeds to S206. In other words, if the recording length of a video file determined to need to be restored is less than the predetermined recording length, editing of the additional information file is not permitted (prohibited), regardless of whether the additional information file needs to be restored.

[0042] In S302, similarly to S203, the additional information file repair determination unit 109 determines whether the additional information file for which editing has been requested is a file that needs to be repaired. 3 If it is determined that the item does not require repair, the process proceeds to S204.

[0043] In S303, the control unit 102 acquires version information of the video file and the additional information file and determines whether the video file and the additional information file are compatible. In this embodiment, version information is used, but other information may be used to determine compatibility between the video file and the additional information file. If it is determined that they are compatible, the process proceeds to S304, and if it is determined that they are not compatible, the process proceeds to S206.

[0044] In S304, the control unit 102 identifies items of additional information in the additional information file that are to be repaired for editing the additional information file that is requested to be repaired. The control unit 102 then prohibits editing of the items that are to be repaired and allows editing of the items that are not to be repaired. The control unit 102 then notifies the external device via the communication unit 112 that the items in the additional information file that are to be repaired are not editable, while the items that are not to be repaired are editable. The control unit 102 may also notify the external device of the names of the additional information items in the additional information file that are editable and those that are not editable. In S305, the control unit 102 executes editing of the additional information file by the additional information file editing unit 110 in response to the editing request, only for the additional information items that have become editable. When the editing process is complete, the control unit 102 notifies the external device via the communication unit 112 that the editing process has been executed. The control unit 102 may also notify the external device of the names of the items that were requested to be edited but were not editable.

[0045] According to this embodiment, even if a video file needs to be repaired, if the recording length of the video file is greater than a predetermined value and the additional information file does not need to be repaired, editing of the additional information file is permitted, as it is considered that this will not affect subsequent repair processing.

[0046] Furthermore, even if an additional information file requires restoration, if certain conditions are met (the video file is not a restoration target, or the video file and the additional information file are compatible), editing is not prohibited and editing of only some of the additional information items is permitted. By permitting editing to the extent that it does not affect the subsequent restoration process for the additional information file, usability is improved. Furthermore, if a video file requires restoration and is less than a specified recording length, editing of the additional information file is prohibited, taking into consideration that the video file will be deleted in the subsequent restoration process for the video file.

[0047] In this way, the status of the video file and the additional information file is not only determined as to whether they need to be repaired, but is also determined in detail, and editing is possible to the extent that it does not affect subsequent repair processing, thereby improving usability.

[0048] <Other embodiments> While the present invention has been described in detail above based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Parts of the above-described embodiments may be combined as appropriate.

[0049] The present invention also includes cases where a software program that realizes the functions of the above-described embodiments is supplied to a system or device having a computer that can execute the program directly from a recording medium or via wired / wireless communication, and the program is executed.

[0050] Therefore, the program code itself that is supplied to and installed on a computer to realize the functional processing of the present invention also realizes the present invention. In other words, the computer program itself for realizing the functional processing of the present invention is also included in the present invention.

[0051] In this case, as long as it has the functionality of a program, the form of the program does not matter, such as object code, a program executed by an interpreter, or script data supplied to the OS.

[0052] The recording medium for supplying the program may be, for example, a hard disk, a magnetic recording medium such as a magnetic tape, an optical / magneto-optical storage medium, or a non-volatile semiconductor memory.
