Description

  The present invention relates to a playback device, a playback method, and a program, and more particularly to a playback device, a playback method, and a program that allow a user to easily grasp the entire contents of a moving image.

  Conventionally, external devices such as a tuner that receives a television program transmitted by a broadcast signal and a video player that reproduces moving images are connected to the personal computer, and moving images are supplied from these external devices. . The personal computer displays the moving image supplied from the external device on the display or stores it in the hard disk.

  In addition, when the video to be stored in the hard disk is composed of a plurality of scenes, the personal computer acquires thumbnails of still images corresponding to the first frame of each scene constituting the video, and these thumbnails are combined with the video. Save to hard disk. Thereafter, when the moving image is reproduced, the personal computer reads a plurality of thumbnails stored together with the moving image from the hard disk, and generates a film roll image in which the thumbnails are arranged in a row in a so-called film roll shape. And a personal computer displays a film roll image with a moving image on a display.

  In this way, the personal computer displays the film roll image corresponding to the moving image to be reproduced on the display, so that the user can refer to the thumbnail of the film roll image to grasp the content of the moving image or perform desired reproduction. You can find the location.

  For example, the personal computer displays the film roll image so that the thumbnails are arranged in a line in the horizontal direction of the display, but the number of thumbnails increases as the number of scenes included in the moving image to be reproduced increases. . If the number of thumbnails exceeds the number that can be displayed in the horizontal width of the display, for example, the personal computer displays only a part of the film roll image on the display and slides the film roll image left and right. The scroll bar used for the is displayed on the display.

  For example, the scroll bar is provided with a slider that can move in the left-right direction, and a film roll image that has been slid left and right is displayed on the display in response to an operation on the slider by the user. In this way, the user can appropriately view all the thumbnails arranged in the film roll image by sliding the film roll image. However, when the user slides the film roll image, for example, the thumbnails of the front part of the moving image and the thumbnails of the rear part are displayed on the display, and only the thumbnails for each part collected in time are displayed. , It was difficult to grasp the overall content of the video.

  In addition, in an editing apparatus that edits a moving image, a technique is disclosed in which a still image corresponding to a scene switching time of a moving image to be edited is displayed at a position corresponding to an interval of scene switching times (for example, , See Patent Document 1).

  A removable medium 22 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 21. The drive 21 reads data recorded on the removable medium 22 or records predetermined data on the removable medium 22. Further, when the removable medium 22 in which the program executed by the CPU 12 is recorded is loaded in the drive 21, the program is read out by the drive 21 and stored in the storage unit 19 via the input / output interface 16 as necessary. Installed.

  The program executed by the CPU 12 is installed in the storage unit 19 via the removable medium 22 as described above, and is downloaded to the personal computer 11 from the download site via a satellite for digital satellite broadcasting. Alternatively, it can be downloaded via a network such as a LAN or the Internet. The personal computer 11 can install the downloaded program in the storage unit 19 as necessary.

  In the personal computer 11 configured as described above, the content stored in the storage unit 19 is reproduced according to the program executed by the CPU 12, and the moving image of the content is displayed on the display 23.

  In addition to the video to be played, the display 23 includes, for example, operation buttons for accepting operations such as playback and stop by the user, and thumbnails of still images representing scenes of the video to be played in a film roll shape. A film roll image arranged in a row is also displayed.

  Next, a screen displayed on the display 23 of FIG. 1 will be described with reference to FIG.

  FIG. 2 shows a player screen 31 that displays a moving image to be reproduced. Also, below the player screen 31, a film roll image 41 is shown in which thumbnails of still images representing each scene of a moving image to be played are arranged in a line in a film roll shape.

  On the player screen 31, a moving image display unit 32, an operation unit 33, a film roll image display unit 34, a pointer 35, a scroll bar 36, and a zoom bar 37 are displayed.

  The moving image display unit 32 is an area where a moving image to be reproduced is displayed.

  The operation unit 33 is an area where buttons operated by the user are displayed. In the example of FIG. 2, a play button that is operated when playing or pausing a moving image, a stop button that is operated when stopping the moving image that is being played back, or a button that is operated when rewinding the moving image. A fast-reverse button, a fast-forward button that is operated when fast-forwarding the playback of a movie, a skip button that skips playback of the movie for each scene, and the like are displayed.

  The film roll image display unit 34 is an area where a film roll image 41 corresponding to a moving image to be reproduced is displayed. In the example of FIG. 2, a part of the film roll image 41 is displayed.

  Here, in the film roll image 41, thumbnails of still images representing each scene of the moving image to be reproduced are arranged in a line in a film roll form in the order of the reproduction times of the scenes corresponding to the respective thumbnails. For example, when the number of thumbnails is 7, thumbnails A to G are arranged as in a film roll image 41 shown in the lower part of FIG.

  In the example of FIG. 2, the film roll image 41 represents the progress of the playback time of the moving image from the left side to the right side in the horizontal direction. For example, the playback time of the moving image being played is 6 minutes. In some cases, the left end of the film roll image 41 represents the time “0:00” when the reproduction of the moving image starts, and the right end of the film roll image 41 represents the time “6:00” when the reproduction of the moving image ends. Then, the thumbnails A to G are arranged at positions corresponding to the reproduction time, which is the time at which the reproduction of the scene corresponding to each is started. That is, the positions at which the thumbnails A to G are arranged are determined based on the playback time intervals of the scenes corresponding to the thumbnails A to G.

  For example, if the playback time of the scene corresponding to the thumbnail A is “0:00”, the thumbnail A is displayed at a position where the left end is the left end of the film roll image 41. If the playback time of the scene corresponding to the thumbnail B is “2:00”, the left end of the thumbnail B is displayed at a position corresponding to the playback time “2:00” of the film roll image 41. Similarly, thumbnails D to G are displayed at positions corresponding to the respective reproduction times.

  Further, a broken-line square frame surrounding the left side of the film roll image 41 (that is, the front side as the reproduction time) is a display area 42 representing a range in which the film roll image 41 is displayed on the film roll image display unit 34, That is, the range of the display area 42 is displayed on the film roll image display unit 34.

  The pointer 35 represents the current time of the moving image that is being played back, is displayed at a position corresponding to the playback time of the image displayed on the video display unit 32, and displays a film roll image as the playback time elapses. The part 34 is moved rightward and displayed.

  The scroll bar 36 is a GUI (Graphical User Interface) operated when scrolling the display of the film roll image 41 in the left-right direction. The scroll bar 36 is provided with a slider 38 that moves in the left-right direction in accordance with a user operation. The film roll image 41 displayed on the film roll image display unit 34 is scrolled in accordance with the movement of the slider 38. To do. That is, the display area 42 of the film roll image 41 moves to the left and right in response to the movement of the slider, and the film roll image 41 within the display area 42 according to the movement moves to the film roll image display unit 34. Is displayed.

  The zoom bar 37 is a GUI operated when the display of the film roll image 41 is enlarged or reduced. The zoom bar 37 is provided with a slider 39 that moves in the left-right direction in response to a user operation. In response to the movement of the slider 39, the display of the film roll image 41 displayed on the film roll image display unit 34 is displayed. Is scaled up or down. That is, the film whose length in the left-right direction of the film roll image 41 is enlarged or reduced with respect to the display area 42 in response to the movement of the slider 39 and falls within the range of the display area 42 according to the enlargement or reduction. A roll image 41 is displayed on the film roll image display unit 34.

  For example, in the example of FIG. 2, the slider 39 is arranged at the right end, and in this state, the most enlarged film roll image 41 is displayed on the film roll image display unit 34. When the user operates the slider 39 to move leftward, the film roll image 41 reduced according to the amount of movement is displayed on the film roll image display unit 34.

  That is, FIG. 3 is a diagram illustrating an example in which a film roll image 41 reduced according to a user operation is displayed on the film roll image display unit 34.

  On the left side of FIG. 3, as in FIG. 2, a player screen 31 in which the most expanded film roll image 41 is displayed on the film roll image display unit 34 is shown. When the user operates the slider 39 to move the slider 39 to the center in the left-right direction of the zoom bar 37, the film roll image 41 is reduced and displayed as shown in the center of FIG. .

  That is, when the film roll image 41 is displayed in a reduced size, when the film roll image 41 is displayed in the largest size, a thumbnail that has not been placed at the position displayed on the film roll image display unit 34 is displayed. Is displayed on the film roll image display unit 34. Specifically, thumbnails B, C, and the like arranged on the right side of the display area 42 in FIG. 2 are arranged within the display area 42 by reducing the film roll image 41. As described above, thumbnails that are not displayed in the film roll image display unit 34 on the left side of FIG. 3 are also displayed in the film roll image display unit 34 in the center of FIG. In addition, on the right side of the film roll image display unit 34 in the center of FIG. 3, the film roll image 41 is displayed in a reduced size, so that the interval between the thumbnails is reduced and the thumbnails are displayed in an overlapping manner. .

  When the user further operates the zoom bar 37 to move the slider 39 to the left side of the center in the left-right direction of the zoom bar 37, the film roll image is displayed as in the player screen 31 shown on the right side of FIG. 41 is further reduced and displayed.

  That is, the film roll image 41 is further reduced, and the entire film roll image 41 is displayed on the film roll image display unit 34 of the player screen 31 shown on the right side of FIG. In the film roll image display unit 34 on the right side of FIG. 3, only the first and last thumbnails of the thumbnails of the film roll image 41 are displayed. In other words, the film roll image display unit 34 on the right side of FIG. 3 displays a film roll image 41 in which thumbnails other than the first and last thumbnails are thinned out.

  As described above, in the film roll image 41, the thumbnails are arranged so that the left end thereof is at a position corresponding to the scene reproduction time corresponding to each thumbnail. Then, as the film roll image 41 is reduced and displayed, the position corresponding to the playback time interval becomes narrower, and when the interval between the left ends of adjacent thumbnails becomes narrower than the horizontal width of the thumbnails, As shown in the center of FIG. 3, thumbnails are displayed in an overlapping manner.

  When the film roll image 41 is further reduced, the overlapping of the thumbnails increases, and the thumbnail display becomes narrow so that the user cannot recognize the scene even when viewing the thumbnails. Therefore, for example, by selecting one of the thumbnails displayed in a superimposed manner and thinning out the thumbnails displayed on the film roll image 41, it is possible to prevent the thumbnail display from being narrowed. It is thought that the scene can be recognized by looking at the thumbnail, and it becomes easier to grasp the moving image.

  That is, FIG. 4 is a diagram for explaining the film roll image 41 with thumbnails thinned out.

When the user operates to reduce the film roll image 41 while the film roll image 41 having a size as shown in FIG. 4 is displayed, the film roll image 41 is reduced in the horizontal direction. The film roll image 41 ₁ is shown below.

As described above, the thumbnails A to G are arranged at locations corresponding to the playback times of the scenes corresponding to the respective thumbnails, and the interval between the thumbnails A to G is reduced as the film roll image 41 is reduced. . Thereby, in the film roll image 41 ₁ , the thumbnails B to E are arranged so as to overlap each other.

Here, a section in which only one thumbnail can be displayed is set in the display area 42. In the example of FIG. 4, predetermined sections L _{1 to} L having a length approximately equal to the horizontal width of the thumbnail. _K is set. Then, for each section, it is determined whether or not a plurality of thumbnails are arranged. In a section where a plurality of thumbnails are arranged, one of the plurality of thumbnails is selected.

For example, as shown in FIG. 4, the film roll image 41 _1, the section L _k, it means that the thumbnail B to D are disposed, the thumbnail to be placed in the section L _k is selected only one. Assuming that the thumbnail to be placed in one section is set to select the first thumbnail among the plurality of thumbnails placed in that section, thumbnail B is selected. That is, the thumbnails C and D are thinned out.

Thus, by thinning out the thumbnails C and D, the entire thumbnail B is displayed like the film roll image 41 ₂ displayed below the film roll image 41 ₁ .

Thus, the user, as in the case where the film roll image 41 ₁ is displayed, but can not grasp the scene corresponding to the thumbnail C and D, different from the case of the film roll image 41 ₁ is displayed, The scene corresponding to the thumbnail B can be grasped. That is, by thinning out thumbnails, the number of scenes that the user can grasp increases.

  As shown in FIG. 4, when the pointer 35 is displayed near the left end of the film roll image 41, the left end of the film roll image 41 is not displayed inside the left end of the film roll image display unit 34. Thus, the reduction of the film roll image 41 is performed with the left end of the film roll image 41 as the center. On the other hand, for example, when the pointer 35 is displayed at the center of the film roll image 41 (other than near both ends), the reduction of the film roll image 41 is performed with the pointer 35 as the center.

  That is, FIG. 5 is a diagram for explaining a film roll image 41 that is reduced around the pointer 35.

When the user operates to reduce the film roll image 41 when the pointer 35 is displayed near the center of the film roll image 41 as shown in FIG. 5, the film shown below the film roll image 41. Like the roll image 41 _3, the image is reduced around the pointer 35.

When the user operates to further reduce the film roll image 41 ₃ , the film roll image 41 ₃ is reduced around the pointer 35 until the left end of the film roll image 41 ₃ overlaps the left end of the display area 42. Like the film roll image 41 ₄ shown below the roll image 41 _3, the image is reduced around the left end of the film roll image 41 ₄ .

  Here, processing for thinning out (selecting) thumbnails when an image displayed on the display 23 is considered in units of pixels will be described.

  For example, when the length of the film roll image display unit 34 is 300 pixels and the magnification of the film roll image 41 displayed on the film roll image display unit 34 is 1, the film roll image display unit 34 includes a film It is assumed that the length of 3600 seconds of the roll image 41 is displayed. In addition, a film roll image 41 corresponding to a portion having m thumbnails in n seconds of a moving image being displayed is displayed on the film roll image display unit 34, and corresponds to a section L in which only one thumbnail can be displayed. It is assumed that the number of pixels on the film roll image display unit 34 to be performed is Y pixels.

  Then, when the user operates to enlarge or reduce and display the film roll image 41, it is assumed that the magnification of the film roll image 41 displayed on the film roll image display unit 34 is X times.

  In this case, the length of one second of the film roll image 41 is displayed on the film roll image display unit 34 with the number of pixels of 300/3600 × X [pix]. In addition, since m thumbnails are displayed in n seconds of the moving image being played back, m / n thumbnails are displayed in one second, that is, 300/3600 × X [pix]. Therefore, 3600/300 / X × m / n [sheets] of thumbnails are displayed per pixel.

  The number of pixels in the section L is Y pixels. From the number of thumbnails per pixel described above, 3600/300 / X × m / n × Y [sheets] thumbnails are displayed on the Y pixels. . Therefore, the thumbnails are thinned out so that one thumbnail is displayed from the thumbnails of 3600/300 / X × m / n × Y [sheets].

  Next, FIG. 6 is a flowchart for explaining processing in which the personal computer 11 in FIG. 1 displays the film roll image 41.

  The storage unit 19 of the personal computer 11 stores a thumbnail of a still image corresponding to the first frame of a plurality of scenes constituting the moving image together with the moving image. Then, when the user operates to reproduce the moving image stored in the storage unit 19, the personal computer 11 performs a process of displaying the film roll image 41 in parallel with the process of reproducing the moving image. In S <b> 11, the CPU 12 reads (acquires) thumbnails corresponding to all scenes constituting the moving image to be reproduced from the storage unit 19.

  After the process of step S11, the process proceeds to step S12, and the CPU 12 arranges the thumbnails read from the storage unit 19 in step S11 at locations corresponding to the playback times at which scene playback corresponding to the respective thumbnails is started. A film roll image 41 is generated. The CPU 12 draws the film roll image 41 in a predetermined buffer secured in the RAM 14, and the process proceeds to step S13.

  In step S <b> 13, the output unit 18 reads the film roll image 41 drawn on the RAM 14 and displays the film roll image 41 on the display 23.

  After the process of step S13, the process proceeds to step S14, and the CPU 12 waits for the process until a user operation is performed. For example, when the user operates a mouse or the like (not shown) to move the slider 39 of the zoom bar 37, the input unit 17 acquires a signal indicating the moving direction and moving amount of the slider 39 based on the user's operation. . The input unit 17 supplies a signal indicating the moving direction and moving amount of the slider 39 to the CPU 12 via the input / output interface 16 and the bus 15, and the process proceeds to step S15.

  In step S15, the CPU 12 determines whether the user operation is enlargement or reduction of the film roll image 41 based on the signal indicating the moving direction of the slider 39 supplied from the input unit 17 in step S14. judge. For example, if the moving direction of the slider 39 is the right direction, the CPU 12 determines that the user's operation is an enlargement of the film roll image 41, while if the moving direction of the slider 39 is the left direction, the user's operation is Is determined to be a reduction of the film roll image 41.

  In step S15, when the CPU 12 determines that the user operation is enlargement of the film roll image 41, the process proceeds to step S16, and the CPU 12 determines the movement amount of the slider 39 supplied from the input unit 17 in step S14. Based on the signal shown, the film roll image 41 is enlarged at a magnification according to the amount of movement of the slider 39.

  On the other hand, if the CPU 12 determines in step S15 that the user operation is to reduce the film roll image 41, the process proceeds to step S17, and the CPU 12 moves the slider 39 supplied from the input unit 17 in step S14. Based on the signal indicating the amount, the film roll image 41 is reduced at a magnification according to the amount of movement of the slider 39.

  After the process of step S16 or S17, the process proceeds to step S18, and the CPU 12 adjusts the arrangement of the thumbnails so as to correspond to the length of the film roll image 41 after being enlarged or reduced. That is, as the film roll image 41 is enlarged or reduced, the position indicating the reproduction time on the film roll image 41, that is, the position where the thumbnail is arranged is moved, so the CPU 12 enlarges or reduces the film roll image 41. Based on the set magnification, the position indicating the reproduction time on the film roll image 41 is determined, and the arrangement of the thumbnails is adjusted.

  After the process of step S18, the process proceeds to step S19, and can the CPU 12 display all the thumbnails read from the storage unit 19 in step S11 on the film roll image 41 after the arrangement of the thumbnails is adjusted? Determine whether or not. That is, the CPU 12 determines whether it is necessary to thin out thumbnails.

For example, a result of adjusting the arrangement of the thumbnail in step S18, to either the thumbnails one only displayed is to section L ₁ to L _K (FIG. 4), supposed to two or more thumbnails are arranged Then, the CPU 12 determines that not all thumbnails can be displayed. On the other hand, if two or more thumbnails are not to be arranged in all the sections L _{1 to} L _K , the CPU 12 determines that all thumbnails can be displayed.

  If the CPU 12 determines in step S19 that all thumbnails cannot be displayed, the process proceeds to step S20, and thumbnail selection processing for selecting thumbnails is performed. In the thumbnail selection process, a thumbnail to be placed in the film roll image 41 is selected, the process returns to step S12, and the CPU 12 generates a film roll image 41 on which the thumbnail selected in step S20 is displayed. Is performed.

  On the other hand, if the CPU 12 determines in step S19 that all thumbnails can be displayed, the process returns to step S12. In this case, the CPU 12 generates a film roll image 41 on which all thumbnails are displayed based on the arrangement adjusted in the immediately preceding step S18, and thereafter the same processing is performed.

  Next, FIG. 7 is a flowchart illustrating the thumbnail selection process in step S20 of FIG.

  In step S <b> 31, the CPU 12 sets a variable k representing the order of the section L to, for example, 1 as an initial value.

After the processing in step S31, the process proceeds to step S32, CPU 12, as a result of adjusting the arrangement of the thumbnail in step S18 in FIG. 6, and counts the number of thumbnails is to be placed in the section L _k, step S33 Proceed to

In step S33, CPU 12 is the number of thumbnails that was to be placed in the section L _k is two or more, determines whether one, or any of 0 sheets.

In step S33, CPU 12 is, if the number of thumbnails is to be placed in the section L _k is equal to or more than two, the process proceeds to step S34, CPU 12 may, for example, are arranged in the interval L _k Of the thumbnails to be selected, the first thumbnail in time, that is, the thumbnail corresponding to the scene to be reproduced first in the section L _k is selected as the thumbnail to be arranged in the film roll image 41, and the processing is performed in steps. Proceed to S36.

On the other hand, in step S33, CPU 12 is, if the number of thumbnails is to be placed in the section L _k is determined to be one, the process proceeds to step S35, CPU 12 may, subject to the count in step S32 The resulting thumbnail is selected as a thumbnail to be placed on the film roll image 41, and the process proceeds to step S36.

On the other hand, in step S33, CPU 12 is, if the number of thumbnails is to be placed in the section L _k is determined to be 0 Like skips step S34 and S35, the process proceeds to step S36. That is, when the number of thumbnails to be arranged in the section L _k is zero, no thumbnail is selected in the section L _k because no thumbnail is arranged.

  In step S36, the CPU 12 determines whether or not the variable k is smaller than a set value K, which is the number for which the section L is set.

  If the CPU 12 determines in step S36 that the variable k is smaller than the set value K, the process proceeds to step S37, the CPU 12 increments the variable k by 1, and the process returns to step S23. Thereafter, the same processing is performed.

  On the other hand, if the CPU 12 determines in step S36 that the variable k is not smaller than the set value K (is greater than or equal to the set value K), the thumbnail selection process ends.

  As described above, since the thumbnail is selected and displayed according to the reduction or enlargement of the film roll image 41, the user can easily grasp the contents of the moving image. In other words, when the thumbnails are displayed in a superimposed manner, the user cannot easily grasp the contents of the scene, but by selecting and displaying the thumbnails, the thumbnails are displayed in a superimposed manner. Can be avoided, and it can be avoided that the user becomes difficult to grasp the contents of the scene.

  That is, when the user wants to know the overall outline of the moving image, the user can enlarge the film roll image 41, and when he wants to know the details of the moving image, the user can simply manipulate the film roll image 41 to reduce the content of the moving image. It can be easily grasped. Thereby, the user can find out a desired reproduction position.

  In the present embodiment, a plurality of thumbnails are arranged in the film roll image 41 according to the playback time of the scene corresponding to each thumbnail. May be arranged at equal intervals.

  That is, FIG. 8 is a diagram illustrating another display example of the film roll image.

  In FIG. 8, a film roll image 41 ′ in which thumbnails A to E are arranged at equal intervals is displayed on the film roll image display section 34 of the player screen 31.

  In this way, when the thumbnails are arranged at equal intervals and the zoom bar 37 is operated by the user, for example, the thumbnails arranged in the film roll image 41 ′ are equally distributed according to the magnification according to the user's operation. Selected. For example, the length of the film roll image 41 ′ when enlarged or reduced at a magnification according to the user's operation with respect to the length of the film roll image 41 ′ when the thumbnails of all scenes of the moving image to be reproduced are arranged. In proportion to the thumbnails of all scenes, specifically, the number of thumbnails of all scenes is 100, and the number of thumbnails that can be arranged in the length of the film roll image 41 ′ is When the number is 10, thumbnails are selected every 10 pages.

  In this way, by displaying thumbnails at equal intervals, the number of thumbnails displayed on the film roll image display unit 34 can be made larger than when thumbnails are arranged according to the playback time of the scene. it can.

  That is, for example, if the playback time of one scene is long, when thumbnails are arranged according to the playback time of the scene, the interval between thumbnails is widened and displayed on the film roll image display unit 34. In some cases, the number of thumbnails was reduced. On the other hand, when displaying thumbnails at equal intervals, even if the playback time of one scene is long, the interval at which the thumbnails are arranged does not increase, so that many thumbnails can be displayed.

  Note that the present invention is applied to, in addition to a personal computer, for example, a video playback device such as a hard disk recorder that stores video on a hard disk or a media player that plays video distributed from a server connected via a network. can do.

  In addition, the processes described with reference to the flowcharts described above do not necessarily have to be processed in time series in the order described in the flowcharts, but are performed in parallel or individually (for example, parallel processes or objects). Processing).

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

It is a block diagram which shows the structural example of one Embodiment of the personal computer to which this invention is applied. 4 is a diagram for explaining a screen displayed on a display 23. FIG. It is a figure explaining the example by which the film roll image 41 reduced according to a user's operation is displayed on the film roll image display part. It is a figure explaining the film roll image 41 by which the thumbnail was thinned. It is a figure explaining the film roll image 41 reduced centering on the pointer. 4 is a flowchart for explaining processing in which the personal computer 11 displays a film roll image 41. It is a flowchart explaining a thumbnail selection process. It is a figure which shows the other example of a display of a film roll image.
