Description

  The present invention relates to a moving image reproduction device, a control method and program for the moving image reproduction device, and a recording medium, and more particularly, a moving image reproduction device that reproduces a moving image to which metadata is added, a control method and program for the moving image reproduction device, and The present invention relates to a recording medium.

  In recent years, moving image playback apparatuses have data to be added to the moving image data in addition to moving image data viewed by the user, and are used for various functions. Data accompanying the moving image data is generally called metadata.

  For example, there is an operation history and operation count for moving image data as metadata to be added to the moving image data, and the operation history and operation count can be displayed (for example, see Patent Document 1). Operation data composed of operation command IDs representing operations on moving image data is created, and operation history display means composed of operation data is provided. The display means displays the number of operations of the operation command ID.

  The display of the number of times of reproduction is generally performed by a music reproduction application or the like executed on a personal computer. As a typical example of a music playback application, iTunes (registered trademark) provided by Apple Inc. in the United States is known.

  There are various types of metadata in addition to the operation history and the number of operations described above. In the moving image data, a plurality of still images are generally continuously displayed at 24 to 60 times per second so that a moving image is shown to the user. The one-screen still image included in the moving image data is generally called a frame. That is, the moving image data is data in which a plurality of frames are continuously stored in time series. In some cases, it is desired to place a mark or mark on a specific frame among a plurality of frames stored in chronological order. Such data specifying a frame is referred to as frame specifying data.

  Since there are a plurality of frames in the moving image data, it is general that the frame specifying data can be added to the plurality of frames. As usage of the frame specifying data, there is one in which a mark is simply added to a particularly important frame in the moving image data. In that case, the user who adds the mark associates a specific meaning with the mark. For example, a mark that is frame specifying data is added to a scene where a score is obtained in a moving image that records a ball sport such as baseball or soccer. There are cases where a mark is added during shooting with a video camera or the like, and there is a case where a mark is added while confirming the shooting contents with a moving image reproducing apparatus after shooting. The scene to get a score is generally considered to be an important scene in ball sports, and the important scene is marked.

  The added mark is illustrated and displayed along with the time axis on the display screen of the moving image playback apparatus. In the case where a plurality of marks are added, it is shown and displayed so that it can be seen where on the time axis the mark is added. Then, the user who views the moving image selects an arbitrary mark from the illustrated marks. After selecting an arbitrary mark, a moving image is reproduced from the frame to which the mark is added by a specific operation. As described above, the frame specific data mark is used to search for a specific frame from a plurality of frames included in the moving image data.

JP 2002-344849 A

  In a conventional moving image reproduction apparatus, a list of reduced representative images of a plurality of moving images is displayed and a specific moving image is selected from among them in order to effectively use a limited display area. Then, the selected specific moving image is displayed in the reproduction display area, and the frame specifying data is displayed on the time axis. Frame identification data cannot be displayed for other moving images that are not selected.

  Similarly, when trying to display the frame specifying data on the time axis in the same manner for all moving images, a large amount of display area is used. However, the display becomes complicated and visibility and operability may deteriorate. This becomes more conspicuous when the display area is limited, such as a notebook personal computer using a limited display area.

  This problem is the same when displaying frame specifying data as a list in addition to displaying frame specifying data on the time axis.

  Also, if no frame specific data is displayed for a non-selected moving image, the frame search cannot be performed using the frame specific data, and therefore a specific frame cannot be reproduced immediately.

  In view of such a situation, the present invention provides a moving image reproducing apparatus, a moving image reproducing apparatus control method, and a program capable of grasping the addition status of frame specifying data even for a non-selected moving image in a list display of a plurality of moving images, The purpose is to present a recording medium.

  The present invention also provides a moving image reproducing apparatus, a moving image reproducing apparatus control method, a program, and a recording medium that can select frame specifying data for a non-selected moving image in a list display of a plurality of moving images and reproduce the corresponding frame. The purpose is to present.

  In order to achieve the above object, a moving image reproducing apparatus according to the present invention is a moving image reproducing device that reproduces a moving image to which one or more frame specifying data indicating one on a time axis is added. Acquisition means for acquiring the number of data of the frame specific data, display means for displaying the number of data, selection means for selecting one frame specific data from the one or more frame specific data, and the selection means Replaying means for replaying the moving image from the frame indicated by the frame specifying data selected by.

  According to the present invention, the number of frame specifying data added to a moving image can be grasped. If the frame specifying data is added by itself, the frame position indicated by the frame specifying data can be easily grasped, and reproduction from the desired frame position indicated by the frame specifying data can be easily realized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of an embodiment of a moving image reproducing apparatus according to the present invention. In the moving image reproducing apparatus 101 shown in FIG. 1, reference numeral 102 denotes a user operation unit, which is configured with members that detect user operations such as a keyboard and a mouse. Reference numeral 103 denotes a system control unit composed of a microcomputer or the like, which analyzes a user operation by the user operation unit 102 and controls each unit of the moving image reproduction apparatus 101 based on the analysis result.

  A reproduction control unit 104 controls reproduction processing based on a control signal from the system control unit 103. A moving image data management unit 105 performs processing related to data management in the reproduction control unit 104. A moving image reproduction processing unit 106 performs processing related to moving image reproduction in the reproduction control unit 104.

  Reference numeral 107 denotes a frame specifying data control unit, which controls the frame specifying data based on a control signal from the system control unit 103. Reference numeral 108 denotes a frame specifying data selection unit, which performs processing for selecting frame specifying data in the frame specifying data control unit 107. Reference numeral 109 denotes a frame specific data number acquisition unit, which performs processing for acquiring the number of frame specific data in the frame specific data control unit 107. Reference numeral 110 denotes a frame specifying data analysis unit, and the frame specifying data control unit 107 analyzes the frame specifying data. Specifically, the frame specifying data analysis unit 10 acquires a time code value set in the frame specifying data.

  Reference numeral 111 denotes a recording medium control unit that reads out clip data 113 including moving image data 114 and management data 115 from the recording medium 112 according to an instruction from the moving image data management unit 105, and reads the read moving image data as a moving image data management unit. 105. As the recording medium 112, a hard disk, an optical disk such as a DVD (trademark) or a BluRay (trademark), a semiconductor memory card, or the like is used. The clip data 113 is a data group serving as a unit for reproducing a series of moving images. Reference numeral 114 denotes moving image data that is actually reproduced and viewed. Reference numeral 115 denotes management data, which includes various data related to the moving image data 114. Reference numeral 116 denotes frame specifying data, which is one of the items included in the management data 115. The moving image data 114 and the management data 115 are combined and handled as clip data 113. It is assumed that one or more frame specifying data 116 is added to the moving image data 114.

  Reference numeral 117 denotes a display control unit which processes the reproduction image data supplied from the moving image reproduction processing unit 106 for display and supplies it to the monitor display circuit 118. The display control unit 117 also receives information on the number of data and the data number from the frame specifying data control unit 107, and uses it for control for display. The display control unit 117 processes the received image data and numerical data so as to match the configuration of the screen, and generates display image data constituting the entire display screen. Reference numeral 118 denotes a monitor display circuit, which converts display image data generated by the display control unit 117 for monitor display and supplies it to the monitor 119. The monitor 119 displays an image according to the signal from the monitor display circuit 118.

  FIG. 2 shows a configuration example of a screen displayed on the monitor 119. Reference numeral 201 denotes the entire screen. Reference numeral 202 denotes a clip list display area, which is an area for displaying a list of clip data recorded on the recording medium 112. Reference numerals 203, 204, and 205 denote thumbnail representative images, and frames representing the clips are displayed as still images from among the frames constituting the moving image of each clip. In the example shown in FIG. 2, three clip data are displayed in the clip list display area 202.

  Reference numerals 206, 207, and 208 denote frame specifying data icons, which are displayed when frame specifying data is recorded in the clip data. In addition, the number of data of the frame specifying data and the data number are simultaneously displayed as numerical values. The number of data and the data number are displayed in a fractional format, the denominator indicates the number of data, and the numerator indicates the data number.

  Reference numeral 209 denotes a clip selection frame. When any one of the thumbnail representative images 203, 204, and 205 is selected and operated by the user operation unit 102, the clip indicated by the thumbnail representative image is selected, but the clip selection frame 209 is selected as such. It shows that. In FIG. 2, the thumbnail representative image 205 is selected.

  Reference numeral 210 denotes a moving image reproduction area. When the user instructs the reproduction of the clip selected in the clip selection frame 209, the corresponding moving image is displayed in the moving image reproduction area 210. 211 is a slider bar, and 212 is a slider. The slider 212 can move in the left-right direction within the display range of the slider bar 211. The total length of the slider bar 211 in the left-right direction indicates the whole of the selected clip on the time axis. The left end of the slider bar 211 indicates the first frame of the clip, and the right end indicates the final frame of the clip. The position where the slider 212 is displayed on the slider bar 211 corresponds to the frame position of the clip being played on the time axis. When starting to play back the clip, the slider 212 is positioned at the left end of the slider bar 211. During playback of a clip, the frame to be played advances and the position of the slider 212 gradually moves to the right.

  The movement of the slider 212 is controlled so that the actual frame playback position is proportional to the position of the slider 212 relative to the slider bar 211. For example, in the case of a clip with a recording time of 30 minutes, when 12 minutes have elapsed since the start of playback from the first frame, 40% of the recording time has been played back. At that time, the display position of the slider 212 is 40% from the left end with respect to the total length of the slider bar 211 in the left-right direction.

  Reference numerals 213, 214, and 215 denote frame specific data marks. In this embodiment, it is assumed that the frame specifying data has been added to the face detected frame. The frame specifying data is data for specifying a specific frame, and is displayed so that the frame position and the mark position are proportional to each other as in the case of the slider 212. For example, in the case of a clip with a recording time of 30 minutes, if the frame position after 9 minutes from the first frame is specified by the frame specifying data, the position 30% from the left end with respect to the total length in the left-right direction of the slider bar 211 A frame specific data mark is displayed on the screen. In FIG. 2, frame specifying data is specified for three frames.

  Reference numeral 216 denotes a top frame button. When the system control unit 103 detects a pressing operation of the top frame button 216 by the user operation unit 102, the system control unit 103 sets the frame to be played back in the moving image playback area 210 as the top frame. Reference numeral 217 denotes a reverse frame feed button. When the system control unit 103 detects a pressing operation of the reverse frame advance button 217 by the user operation unit 102, the system control unit 103 changes the frame to be played back in the moving image playback area 210 to the previous frame from the current frame position.

  Reference numeral 218 denotes a playback stop button. When the system control unit 103 detects the pressing operation of the playback stop button 218 by the user operation unit 102, the system controller 103 starts playback if the playback stop state is before the pressing operation is detected, and stops playback if it is in the playback execution state. Perform a typical operation. Note that what is executed by pressing the playback stop button 218 is playback in real time, so-called 1 × speed playback. Hereinafter, the 1 × speed reproduction is simply referred to as “reproduction”. Further, at the time of the reproduction stop operation, the image displayed in the moving image reproduction area 210 at the time of the stop operation is continuously displayed as it is. This is a so-called pause state. Hereinafter, this is simply referred to as “stop”.

  Reference numeral 219 denotes a forward frame feed button. When the system control unit 103 detects a pressing operation of the forward frame advance button 219 by the user operation unit 102, the system control unit 103 changes the frame to be reproduced in the moving image reproduction area 210 to the next frame from the current frame position. Reference numeral 220 denotes a final frame button. When detecting that the user operation unit 102 has pressed the last frame button 220, the system control unit 103 sets the frame to be reproduced in the moving image reproduction area 210 as the last frame.

  FIG. 3 shows an example of the data structure of data recorded on the recording medium 112. On the recording medium 112, clip data 113, moving image data 114, management data 115, and frame specifying data 116 are recorded.

  Reference numeral 301 denotes clip data, which corresponds to the clip data 113 shown in FIG. Reference numeral 302 denotes moving image data, which corresponds to the moving image data 114 shown in FIG. The moving image data 302 is given a moving image data name “AA01”. Reference numeral 303 denotes management data, which corresponds to the management data 115 shown in FIG. The management data 303 stores two types of data: a moving image data name 304 and frame specifying data 305. The moving image data name 304 is recorded in order to clarify the correspondence between the moving image data 302 and the management data 303.

  The frame specifying data 305 corresponds to the frame specifying data 116 shown in FIG. Reference numeral 306 denotes a time code, and reference numeral 307 denotes a frame specifying data number. The frame specifying data 305 has a list structure, and the time code 306 and the frame specifying data number 307 are items in the list. The time code 306 indicates to which frame the frame specifying data 305 is assigned by a time code. For example, the time code “00: 03: 22: 01” indicates that frame specifying data is assigned to the position of 3 minutes 22 seconds 1 frame. The frame specifying data number 307 assigns a number to each frame specifying data in time code order, that is, in time series order. Incidentally, the list is not always sorted in chronological order. This is because the list is actually placed in memory, and if you delete an item on the list, that part will be blank, and the next time you add to the list, it may be added to that blank part. .

  FIG. 3 shows an example in which lists (or entries) 308, 309, and 310 for three lines exist. Each row corresponds to one frame specifying data. The list 309 corresponds to the frame specifying data mark 213 shown in FIG. The list 308 corresponds to the frame specifying data mark 214 shown in FIG. The list 310 corresponds to the frame specifying data mark 215 shown in FIG.

  FIG. 4 is a flowchart showing the procedure of the reproduction process executed by the system control unit 103. A control program corresponding to the flowchart shown in FIG. 4 is loaded into the system control unit 103 and executed.

  S401 indicates a starting point of the reproduction process control. In S402, the system control unit 103 sets 1 as the initial value for the frame specific data selection number. This means that the initial selection state of the frame specific data is a state in which the first frame specific data is selected in time series.

  In step S <b> 403, the system control unit 103 acquires the frame specific data number of each clip recorded on the recording medium 112. Specifically, the number of frame specific data is obtained by counting the number of rows in the list indicated by the frame specific data 305 shown in FIG.

  In step S <b> 404, the system control unit 103 assigns a data number to the frame specifying data of each clip recorded on the recording medium 112. Specifically, a data number is assigned to the frame specific data number 307 in the list indicated by the frame specific data 305 shown in FIG. When assigning, data numbers are assigned in order of time series according to the value of the time code 306.

  In step S405, the system control unit 103 displays the frame specific data icon and the number of frame specific data. In step S406, the system control unit 103 acquires a thumbnail image corresponding to the frame specifying data selection number. Specifically, the system control unit 103 searches for a frame specifying data number that matches the current frame specifying data selection number (for example, 1) from the frame specifying data 305 shown in FIG. In the example illustrated in FIG. 3, the list 309 is the second row of frame specifying data. Then, the system control unit 103 reads the corresponding time code from the column on the list corresponding to the frame specific data number. In this case, 00: 03: 22: 01. The system control unit 103 acquires a frame corresponding to the read time code as a thumbnail image from the moving image data 302 shown in FIG.

  In step S407, the system control unit 103 displays the thumbnail image acquired in step S406 on the monitor 119. In step S408, the system control unit 103 displays the frame specific data selection number on the monitor 119.

  In step S409, the system control unit 103 checks whether the user has clicked the frame specifying data icon. If “yes”, the system control unit 103 proceeds to S410, adds 1 to the frame specific data selection number, executes S408 again, and redisplays the frame specific data selection number on the monitor 119. If “No”, the system control unit 103 proceeds to S411.

  In step S411, the system control unit 103 checks whether the user has clicked on a thumbnail representative image. If “No”, the system control unit 103 proceeds to S409 again. If “yes”, the system control unit 103 proceeds to S412. In step S412, the system control unit 103 selects a frame corresponding to the frame specifying data selection number of the clip for which the thumbnail has been clicked, and causes the monitor 119 to reproduce and display the frame. Specifically, the system control unit 103 searches the frame specifying data 305 shown in FIG. 3 for a frame specifying data number that matches the current frame specifying data selection number (for example, 2). In this case, the list 308 is the first line of the frame specifying data. Then, the system control unit 103 reads the corresponding time code from the column on the list corresponding to the frame specific data number. In this case, 00: 06: 09: 22. The system control unit 103 acquires a frame corresponding to the read time code from the moving image data 302 shown in FIG. 3, and starts playback using the frame as a playback start frame.

  S410 indicates the end of the process.

  Since the number of frame specific data is displayed in the clip list display area, how many frame specific data are recorded by the user even for non-selected clips for which no frame specific data is displayed on the slider bar at the bottom of the screen Can be grasped. Also, by clicking on the frame specific data icon, the frame specific data can be selected. Furthermore, it is possible to directly select each frame specifying data of each clip and reproduce directly from the corresponding frame without going through the procedure of selecting the frame specifying data after selecting the clip. That is, reproduction of a desired scene from a desired screen can be started quickly.

  FIG. 5 shows another screen configuration example displayed on the monitor 119. Reference numerals 501, 502, and 503 denote frame specifying data icons. In the first embodiment, the data number and the number of data are displayed as fractions, but in this embodiment, only the number of data is initially displayed. Reference numerals 504, 505, and 506 denote data numbers. In this embodiment, data numbers 504, 505, and 506 are superimposed and displayed on the thumbnail representative images 203, 204, and 205, respectively. When one of the frame specifying data icons 501, 502, and 503 is clicked, the data numbers 504, 505, and 506 are updated. At the same time, the thumbnail representative images 203, 204, and 205 are updated and displayed as images acquired from the frames corresponding to the data numbers 504, 505, and 506.

  FIG. 6 is a flowchart showing the procedure of the reproduction process executed by the system control unit 103 corresponding to the screen configuration shown in FIG.

  In FIG. 4, the system control unit 103 proceeds to step S <b> 408 after executing step S <b> 410 and displays the frame specific data selection number, that is, performs display update. On the other hand, in the flow shown in FIG. 6, the system control unit 103 proceeds to S406 after executing S410, and acquires a thumbnail image corresponding to the frame specifying data selection number. Then, the system control unit 103 proceeds to S407 and displays a thumbnail image. The system control unit 103 proceeds to S408 and displays the frame specific data selection number as in FIG. That is, the float shown in FIG. 4 is different in that thumbnail images are reacquired and redisplayed.

  In the flow shown in FIG. 6, when the frame specifying data icon is clicked to select the frame specifying data, the thumbnail representative image is also updated in conjunction with it, so that the selection of the frame specifying data is further facilitated.

  FIG. 7 shows still another screen configuration example displayed on the monitor 119. In the example shown in FIG. 7, there is no display corresponding to the data numbers 504, 505, and 506 in the example shown in FIG. Instead, the functions of the clip specific data icons 701, 702, and 703 are changed. That is, the system control unit 103 displays the clip specific data selection number only within a set time (for example, 3 seconds) after the clip specific data icons 701, 702, and 703 are clicked. The system control unit 103 displays the number of clip specific data except within the set time. In other words, the content of the numerical value to be displayed is switched depending on whether or not the clip specifying data icon is clicked. Generally speaking, the clip specific data selection number is displayed during a specific selection operation, and the number of clip specific data is displayed during other than the specific selection operation.

  When the display of the clip specific data selection number and the display of the number of clip specific data are switched, the character display form is changed. For example, when the clip specific data selection number is displayed, it is displayed with characters twice as large as when the clip specific data number is displayed. In addition, it is possible to provide various character display modes that are effective for notifying the user that the display content has been changed, such as changing the color of the display character, making it italic character, or flashing the character.

  In particular, in the case of a notebook personal computer or the like, the area of the display screen region is often limited. In such a case, by switching the display mode, more information can be transmitted to the user with a smaller display screen area.

  FIG. 8 shows still another screen configuration example displayed on the monitor 119. In the example shown in FIG. 8, a frame specifying data button 801 is added to the example shown in FIG.

  The user reproduces the clip, confirms the content, and stops reproduction at the frame to which the frame specific data mark is to be added. For example, if you want to add a mark to a scoring scene with moving image data that records a soccer game pattern such as soccer, the user visually checks the contents while playing the clip, and stops playback on the screen where the scoring scene is To do. In this state, the user presses the frame specifying data button 801 by a mouse click operation of the user operation unit 102 or the like. When the frame specifying data button 801 is pressed, the system control unit 103 adds a frame specifying data mark to the frame that is currently stopped. Specifically, an entry of frame specific data is newly added to the list of frame specific data 305 shown in FIG. The time code set in the entry is a time code corresponding to the frame whose reproduction has been stopped when the frame specifying data button 801 is pressed.

  Since the user adds the frame specifying data by his / her own operation, the number of places where the frame specifying data is added can be associated with the user's own memory. Thereby, the display of the number of frame specific data becomes effective.

  There are various methods for selecting the data number of the frame specifying data by the user operation unit 102. For example, the data number is incremented by 1 each time the mouse is clicked on the frame specific data icon. Further, by dragging the mouse with the mouse clicked on the frame specific data icon, a numerical value proportional to the amount of movement of the mouse is added to or subtracted from the data number as a change amount. After the frame specific data icon is selected by mouse click or the like, a numerical value proportional to the operation amount of the scroll wheel is added to or subtracted from the data number by operation of the scroll wheel attached to the mouse. Furthermore, after the frame specific data icon is selected by mouse click or the like, the data number is designated by directly inputting a numerical value from the keyboard.

  Although this embodiment has been described with respect to a moving image playback apparatus, it can also be realized as a moving image playback program executed on a personal computer or the like. Further, the present embodiment may be implemented in a form in which the moving picture reproducing apparatus and the moving picture recording apparatus are combined, for example, a video camera.

  It goes without saying that the functions of the control units 103, 104, 107, and 117 that execute the control operations described above may be realized by a single hardware or by a plurality of hardware operating together. Nor.

  The present invention can be applied not only to a device having only a function of reproducing a moving image, but also to a moving image recording / reproducing device, a moving image reproducing program and a moving image recording / reproducing program operating on a computer.

  The present invention is also realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads the program code. It is a process to be executed. In this case, the program and the storage medium storing the program constitute the present invention.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. .
