Description

  The present invention relates to a video editing technique and a user interface technique for changing the start time or end time of an arbitrary scene section among a plurality of scene sections existing in a video.

  In recent years, due to advances in digitization technology for video data, a time for defining a plurality of scene sections for video data, or for referring to scene contents in a video such as the start time and end time of a scene section once defined It is now possible to easily change the screen with a non-linear video editor. Specifically, a non-linear editing machine is composed of a computer and software having a video editing function. Conventional typical non-linear editing machines include “Media Composer” of Avid USA and “Premiere” of Adobe Corporation.

  As an example of an operation for changing time information recorded in advance in order to refer to the scene contents in the video in these nonlinear editing machines, there is an operation for changing the start time of the scene section in the video. In the conventional operation of changing the start time of a scene section in a video, first, a frame image corresponding to the start time of the scene section to be changed is displayed on a user interface such as a video player screen. On the other hand, the user can freely change the image content on the video player from a coarse granularity to a fine granularity on a frame basis by using the playback control functions of the video player such as fast forward, rewind, frame advance, and frame reverse. Then, when it matches the image content to be changed as the start image of the scene, an operation for changing the time as the start time of the scene section is performed.

  FIG. 7 is a diagram showing an example of a conventional user interface screen for explaining a conventional technique for changing the time for scene reference in video. In FIG. 7, reference numeral 20 denotes a reproduction monitor that reproduces an image, and reference numeral 21 denotes an image displayed on the reproduction monitor 20. Reference numeral 22 denotes an operation button for using functions of the video player such as playback, fast forward, rewind, frame advance, and frame reverse.

  In the prior art, the video 21 at time T (frame image F (T)) is displayed on the reproduction monitor 20, and then the user confirms the content of the frame image corresponding to the reference time of the scene to be changed. The operation buttons 22 such as playback, fast forward, rewind, frame advance, and frame return are operated to change the contents of the video 21 displayed on the playback monitor 20. When the frame image of the scene to be changed is displayed, the reference time of the scene is changed.

  As described above, in the conventional technology, in order to change the time information acquired in advance to refer to the scene contents in the video, playback, fast forward, rewind, The user interface such as frame advance and frame return is used to freely specify the scene to be confirmed in the video, while visually confirming the video content at the specified time. Video time designation operations on the video player use information input devices for computers such as mice and keyboards, or playback control buttons specific to VCRs, and jog shuttles for frame advance and rewind, especially in frame units. ing.

A method for automatically detecting and recording scene switching time information from a video is described in Patent Document 1 below.
Japanese Patent No. 2839132

  However, in the above-described conventional technique, a user screen is used because a moving image display interface such as a video player is used when changing time information acquired in advance to refer to scene contents in a video. In the above, only one frame image could be confirmed visually. For this reason, it takes time to search for a frame image corresponding to the time to be changed, and there is a problem that the efficiency of editing work is deteriorated.

  For example, when it is actually desired to set a certain time for scene reference in the video to a time before that time, a playback operation is performed in the first operation, and subsequent frame images are referred to. After the reproduction, the rework of the operation of going back and confirming the frame image display from the time again occurs.

  Also, even if you actually want to change a scene reference time in the video to a time that is one minute later than the actual time, check the frame image while performing frame-by-frame advance at the first operation. As a result, if it takes 1 second for frame advance and image confirmation of one frame, it will take 30 minutes, and the efficiency of the editing work will also deteriorate.

  In recent years, with the spread of the Internet, various data has been distributed and exchanged over the network. In video editing work, the video editing machine and the actual video data to be edited are networked. In some cases, it exists remotely. For example, video data exists as a video file on the computer of the company that shot the video, and the editing machine that edits the video data is a video editing company that exists remotely from the shooting company in terms of network. May be a computer. In such a case, it is necessary to access the video data to be edited through the network and perform video editing work.

  On the other hand, streaming technology is generally used when performing operations such as access to video data over a network and playback. The streaming technology is a technology for downloading video data in a remote place by downloading an appropriate amount of data without downloading the entire data, and smoothly reproducing the video without delay as much as possible with respect to user operations. However, the delay time for the user operation is always small in principle, and depending on the network situation, it may be several seconds if it is short, but it may be several minutes if it is too long. May not be able to be played.

  When streaming video is used to access video data over a network and video editing is performed, the operability of the operation for freely changing the image on the video player as described in the above-mentioned conventional technology is deteriorated. There is a problem that the efficiency of the entire editing work is deteriorated. Specifically, for example, when changing the start time of a changed scene section, using the conventional technology, the user starts cueing playback of the video from the start time, and performs operations such as frame advancement in the middle. However, while confirming the image contents visually, the task of searching for a suitable time as the start time of the scene section is carried out, but after issuing instructions for video playback and frame advance, Depending on the situation, you may have to wait for a few seconds to a few minutes.

  In the conventional technology, the video data to be edited does not exist remotely from the video editor, but exists as digital data residing on the hard disk on the video editor. Because it was a presupposed method, editing using a video player was effective. However, when accessing video data over a network, the above-mentioned problems occur. For example, even if the image content on the video player is to be changed in units of frames instantaneously, such as frame advance, Will have to wait for at least a few seconds, making the editing work less efficient, so this problem needs to be solved.

  In the example of the prior art shown in FIG. 7, when video data exists in a remote place, a waiting time of several seconds to several minutes occurs every time the playback button or the frame advance button is pressed once in the video player. For this reason, for example, if you want to display a frame image after 4 seconds, it takes about 3 minutes to play for about 3 seconds, and the remaining 1 second is adjusted by frame advance. The work efficiency is very bad.

  The present invention has been made in consideration of the above points, and when performing video editing work for changing time information already recorded in order to refer to the contents of a scene in the video, one frame at a time. It has already been recorded to solve the problem of reducing the work efficiency of editing work because only images can be confirmed, and to access the video data over the network and refer to the scene contents in the video An object of the present invention is to enable efficient execution of a work without waiting for a user to perform an editing operation even when a video editing work for changing time information is performed.

  In order to solve the above-described problem, a method for changing a time for scene reference in a video according to a first aspect of the present invention includes a frame image in a video corresponding to a time recorded in advance to refer to the scene contents in the video, and A plurality of frame image acquisition steps for acquiring frame images corresponding to a plurality of times separated by predetermined intervals before and after the time as image data from the video, and the plurality of frame image acquisition steps acquired in the plurality of frame image acquisition steps A plurality of frame image display steps for displaying a frame image in a video corresponding to a pre-recorded time, and a plurality of frame images corresponding to a plurality of times separated from the time by a predetermined interval; Referencing the contents of the scene for the time corresponding to the designated frame image from among the plurality of frame images displayed in the frame image display stage And having a time information changing step of changing replace the record and have time information.

  In order to solve the above-mentioned problem, the scene reference time changing method in the video of the second invention is characterized in that the multi-frame image display step includes a time interval value of a plurality of frame images in the video to be displayed. A time interval value designating step for designating the frame image, a frame image in the video corresponding to the prerecorded time, and an interval value designated in the time interval value designating step before and after the prerecorded time. And a step of displaying frame images corresponding to a plurality of separated times.

  In order to solve the above-described problem, a scene reference time changing device in a video according to a third aspect of the present invention provides a frame image in a video corresponding to a time recorded in advance to refer to the scene contents in the video. , And a plurality of frame image acquisition means for acquiring, as image data, frame images corresponding to a plurality of times separated by predetermined intervals before and after the time, and acquired by the plurality of frame image acquisition means A plurality of frame image display means for displaying a frame image in the video corresponding to the pre-recorded time, and a frame image corresponding to a plurality of times separated from the time by a predetermined interval; Refer to the contents of the scene for the time corresponding to the designated frame image from the plurality of frame images displayed by the multi-frame image display means. Time information changing means that replaces and changes the time information that has been recorded, processing control means for controlling the multiple frame image acquisition means, the multiple frame image display means, and the time information change means, video data, Data storage means for storing frame image data and time information for scene reference in video is provided.

  In order to solve the above-described problem, in the scene reference time changing device in the video of the fourth invention, the multiple frame image display means designates time interval values of the multiple frame images in the video to be displayed. The time interval value designating means is separated from the frame image in the video corresponding to the pre-recorded time and the interval value designated by the time interval value designating means before and after the pre-recorded time. And a means for displaying frame images corresponding to a plurality of times.

  In order to solve the above-mentioned problem, a program for realizing a scene reference time changing method in a video according to a fifth aspect of the invention is a program according to any one of the steps in the scene reference time changing method in a video according to the first or second aspect. Is configured as a program for causing a computer to execute.

  In order to solve the above-mentioned problem, a recording medium on which a program for realizing the method for changing the time for scene reference in a video according to the sixth invention is recorded is the time for scene reference in a video according to the first or second invention. A program for causing a computer to execute each step in the changing method is recorded on a recording medium readable by the computer.

  The operation of the present invention is as follows. In the present invention, when the time for referring to the scene contents in the video is changed, a plurality of frame images in the video corresponding to the time and the time in the vicinity thereof are displayed on the user screen. By simply selecting an image content to be changed as a reference image from a plurality of frame images arranged on the top, it is possible to change the time for referring to the scene content.

  That is, according to the present invention, the frame image corresponding to the time to be changed in the video and the images of a plurality of neighboring times before and after the time can be confirmed at the same time. Furthermore, since the time width of the plurality of neighboring times before and after the time can be set to an arbitrary value and the granularity of the neighborhood range can be changed, the frame images before and after the range of several seconds, or several minutes Even the frame images before and after the range can be confirmed with less operation time. As a result, the rework of the operation can be minimized, and the operation time required for editing can be shortened as compared with the prior art.

  In addition, according to the present invention, even when editing video data that exists at a remote location on a network, the user only needs to download a predetermined number of still image data once and then refer to the change target. You can immediately know the image content near the working time. Since the download capacity of still image data is a small amount that is one tenth or less of the download amount by streaming of video data in the prior art, the user can work efficiently without waiting time.

  For example, in the case of the prior art, it is assumed that a waiting time of 5 seconds occurs every time a single operation such as playback on a video player or frame advance is performed, depending on the network traffic situation. In this case, it takes 50 seconds (= 5 seconds × 10 frames) to advance 10 frames ahead by frame advance. On the other hand, according to the present invention, it is only necessary to download and display a frame image 10 frames ahead, and the data amount may be a few tenths of that of the prior art. With this waiting time, an image 10 frames ahead can be referred to, so that the work time can be shortened and the problems to be solved by the prior art can be solved.

  The present invention does not perform operations such as direct playback, fast forward, and frame advance on video data when changing time information for scene reference in a video, but a plurality of times corresponding to times near the change target time. This makes it possible to check the frame image to be confirmed in the video with a smaller number of operations and work time than in the prior art. Furthermore, even when the video editor and video data exist remotely over the network, it is possible to change the time information for scene reference in the video in an extremely short time and efficiently compared to the prior art. As a result, the video editing work time can be shortened compared to the conventional technique.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of a configuration of a scene reference time changing device in a video according to the present invention. In FIG. 1, reference numeral 1 denotes a scene reference time changing device in a video comprising a CPU and a memory. In the scene reference time changing device 1 in the video, 11 is a multi-frame image acquisition unit, 12 is a multi-frame image display unit, 13 is a time information change unit, 14 is a processing control unit, and 15 is a data storage unit. In the multi-frame image display unit 12, 121 is a time interval value designation means.

  The multi-frame image acquisition unit 11 includes a plurality of frame images at a time designated by a predetermined method from video data stored in the data storage unit 15 and a predetermined interval before and after the time. A frame image corresponding to the time is acquired as image data from the video. More specifically, the multiple frame image acquisition unit 11 can be realized by a software program developed on a memory of a personal computer. For example, there is a product called MP-Factory of KDDI R & D Labs as a software program that acquires a frame image corresponding to a specified time from a moving image in MPEG format.

  The multi-frame image display unit 12 displays still image data of a plurality of frame images acquired by the multi-frame image acquisition unit 11 stored in the data storage unit 15 on a user screen with a predetermined display layout. It is. The multi-frame image display unit 12 is separated from the frame image in the video corresponding to the pre-recorded time by the interval value specified by the time interval value specifying means 121 before and after the pre-recorded time. Frame images corresponding to a plurality of times can also be displayed.

  Specifically, the multi-frame image display unit 12 can be realized by a software program developed on a memory of a personal computer. For example, it can be realized as software having a graphical user interface (GUI) shown in FIGS.

  The time information changing unit 13 records the time corresponding to the frame image specified by the user from the plurality of frame images displayed on the multi-frame image display unit 12 for referring to the scene contents. To replace and change. The processing control unit 14 controls the multi-frame image acquisition unit 11, the multi-frame image display unit 12, and the time information change unit 13. The data storage unit 15 stores video data, frame image data, and time information for scene reference in the video, and can be realized by a data storage medium such as a hard disk on a computer.

  The time interval value specifying means 121 in the multi-frame image display unit 12 is means for specifying time interval values of a plurality of frame images in the video to be displayed.

  FIG. 2 shows an example of a scene reference time changing process flow in the video according to the first embodiment of the present invention. First, in the multiple frame image acquisition step S1, an arbitrary time selected by the user from among a plurality of time information recorded in advance for referring to the scene contents in the video, and before and after that time are determined in advance. Frame images corresponding to a plurality of times separated by a predetermined interval are acquired as image data from the video. Specifically, this can be realized by using software on a computer that outputs image data to be acquired when video data and time information in the video corresponding to the image data to be acquired are input.

  The time information recorded in advance for referring to the scene contents in the video, which is the premise of the present invention, is described in, for example, the video described in Patent Document 1 (video cut point detection method and apparatus). It can be acquired by applying a method of automatically detecting and recording scene switching time information. Alternatively, instead of automatically, the user may acquire the time by manually recording the scene time to be referred to while visually referring to the video data on the video player.

  In addition, when a plurality of frame image data acquired at this stage is stored in a hard disk on a computer, these images are stored on the hard disk as data when the plurality of frame image data are unnecessary. Instead, it is possible to save the amount of use of the hard disk by acquiring the necessary amount of image data only when there is an instruction from the user and storing it on the hard disk.

  Next, in the multi-frame image display step S2, a time selected by the user from a plurality of time information recorded in advance to refer to the scene contents in the video acquired in the multi-frame image acquisition step S1, A frame image corresponding to a plurality of times separated from the time by a predetermined interval is displayed.

  A specific display example in the multi-frame image display step S2 is shown in FIG. FIG. 3 shows an example of a user interface screen according to the present invention, and among the plurality of image displays 101 to 107, reference numeral 104 denotes a frame image F (corresponding to an already recorded scene reference time T ( T) is displayed. Reference numerals 101 to 103 denote frame images F (T-6 seconds), F (T-4 seconds), and F (T-2 seconds) that exist at equal intervals of 2 seconds before time T. Shows frame images F (T + 2 seconds), F (T + 4 seconds), and F (T + 6 seconds) that exist at equal intervals of 2 seconds after time T.

  It should be noted that the frame image F (T) 104 is the same image as the display image of the video 21 in FIG. 7 showing the conventional scene reference time changing technique in the video.

  For example, the user records the time T in the video to refer to the “scene of Kumamoto Castle” displayed in the frame image F (T) 104 in FIG. In the following, the embodiment of the present invention will be described in comparison with the prior art based on this assumption.

  In the prior art, as described with reference to FIG. 7, the playback button and the frame advance button are operated on the video player to display the frame image corresponding to the time to be changed, and the contents are confirmed. In the embodiment of the present invention, as shown in FIG. 3, the frame image F (T) 104 is centered on F (T-6). By displaying still images from (seconds) 101 to F (T + 6 seconds) 107, the image contents before and after the frame image F (T) 104 can be grasped instantaneously. Thereby, in the prior art, it is possible to instantaneously refer to the image after 4 seconds from the frame image F (T) 104 which took several minutes or more.

  When the frame image corresponding to the time to be changed is confirmed, the time corresponding to the frame image designated by the user from among the plurality of frame images displayed in the multiple frame image display step S2 is determined in the time information change step S3. In order to refer to the contents of the scene, the time information recorded is replaced and changed.

  In FIG. 3, reference numeral 108 denotes a time display area in which the pre-change time corresponding to the frame image F (T) 104 is displayed, and reference numeral 109 denotes a change button for changing the time displayed in the time display area 108. . In the example of FIG. 3, “00: 03: 48: 28” is displayed in the time display area 108 as time information for referring to the contents of the scene.

  When the time displayed in the time display area 108 indicating the start time of the scene is changed to a time corresponding to the frame image F (T + 4 seconds) 106, the frame image of the frame image F (T + 4 seconds) 106 is changed to a mouse or the like. Is selected with the pointing device, and the change button 109 is pressed down. By doing so, the time displayed in the time display area 108 is replaced and changed to the time corresponding to the frame image F (T + 4 seconds) 106. Therefore, according to the present invention, it is possible to change the reference time of the video scene more efficiently in a shorter time than the prior art.

  FIG. 4 is a diagram illustrating an example of a scene reference time change processing flow in a video according to the second embodiment of the present invention, and FIG. 5 illustrates a video in the video according to the second embodiment of the present invention. It is a figure which shows an example of the user interface screen utilized in the time change processing flow for scene references.

  The multi-frame image acquisition step S11 and the time information change step S14 in FIG. 4 are multi-frame images described in the scene reference time change processing flow in the video according to the first embodiment of the present invention shown in FIG. This is the same as the acquisition stage S1 and the time information change stage S3.

  In the time interval value designation step S12 in FIG. 4, the time interval values of a plurality of frame images in the video to be displayed are designated by user input. Specifically, this can be realized by using a user interface including a text input box capable of inputting a numerical value as indicated by 120 in FIG. FIG. 5 shows an example in which “4 seconds” is set as the time interval between frame images in the text input box 120. In FIG. 5, 118 is a time display area where the time corresponding to the frame image F (T) 114 is displayed, and 119 is a change button for changing the time displayed in the time display area 108.

  The multi-frame image display step S13 is a step of displaying frame images corresponding to a plurality of times separated by the interval values specified in the time interval value specifying step S12, and specific steps 111 to 117 in FIG. A user interface screen is shown.

  For example, the images 111 to 117 in FIG. 5 are obtained by displaying frame images in the vicinity of the “Kumamoto Castle scene” in the video at intervals of 4 seconds. That is, the user interface screen shown in FIG. 5 includes a frame image F (T) 114 corresponding to the existing reference time T and a frame image F (T−T) that exists at equal intervals of 4 seconds before the time T. 12 seconds) 111, F (T-8 seconds) 112, F (T-4 seconds) 113, and frame images F (T + 4 seconds) 115, F (T + 8 seconds) that exist at equal intervals of 4 seconds after time T. ) 116, F (T + 12 seconds) 117 are displayed.

  The time interval value designation step S12 and the multi-frame image display step S13 allow the user to freely set the time intervals of the plurality of frame images to be displayed. By shortening the time interval input to the text input box 120, it is possible to list images in a dense range in time, and conversely, by enlarging the time interval, list images in a wide range in time. Can do. This means that information equivalent to the image information obtained by frame advance and fast forward of the video player in the prior art can be instantly provided to the user. In the absence of the time interval value specifying step S12, the user can refer to the frame image only at a predetermined interval value.

  Depending on the editing operation, there may be a case where it is desired to refer to image contents in a fine range in time, and a case where it is desired to refer to image contents in a wide range. Therefore, according to the embodiment of the present invention, it is possible to efficiently grasp a frame image to be confirmed in a short time by changing the time interval of a plurality of frame images displayed on the user interface screen. Thus, the editing work time can be shortened.

  FIG. 6 is a diagram showing a third embodiment of the present invention. The third embodiment of the present invention shown in FIG. 6 employs a configuration in which a video editing computer 31 and a video data storage computer 33 exist remotely on a network and are connected via the Internet 32. That is, in the third embodiment of the present invention, the data storage unit 15 is mounted on the video data storage computer 33 in the scene reference time changing device 1 in the video shown in FIG. Is installed in the video editing computer 32.

  According to the present invention, the video editing computer 31 and the video data storage computer 33 are suitable for video editing stored on the video data storage computer 33 even when the video editing computer 31 and the video data storage computer 33 are remote from each other as shown in FIG. By downloading the still image data and displaying it on the video editing computer 31, it is possible to efficiently execute the video editing work without giving the user a waiting time as in the prior art.

  The above-described scene reference time changing device according to the first to third embodiments of the present invention can be realized by a computer and a software program, and the program is recorded on a computer-readable recording medium. It can be provided via a network.
