  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments (embodiments) for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  The information processing apparatus according to the present embodiment is an apparatus capable of reproducing time-series data (for example, moving image data and music data), and examples thereof include a PC (Personal Computer), a mobile phone, an audio player, and a game machine.

  First, a configuration example of the information processing apparatus according to the present embodiment will be described with reference to FIG.

  As illustrated in FIG. 1, the information processing apparatus according to the present embodiment includes a control unit 1, a storage unit 2, an operation unit 3, and a display unit 4. The control unit 1 is realized by, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The storage unit 2 is realized by a nonvolatile memory such as an HDD (Hard Disk Drive). The operation unit 3 is realized by a mouse, a keyboard, a touch panel, or the like, for example. The display unit 4 is realized by, for example, a liquid crystal display.

  The control unit 1 includes a display control unit 11, an operation detection unit 12, a time series data processing unit 13, and an operation speed detection unit 14.

  The display control unit 11 is a unit that controls display on the display unit 4. For example, the display control unit 11 displays a user interface screen on the display unit 4 and controls the display of the user interface screen according to a user operation and processing related to reproduction of time series data (details will be described later). Details of the user interface screen will be described later with reference to FIG.

  The operation detection unit 12 is a unit that detects an operation performed by the user using the operation unit 3. For example, the operation detection unit 12 detects a user operation performed on the user interface screen.

  The time series data processing means 13 is a means for performing processing related to reproduction of time series data. As processing related to reproduction of time-series data, there are, for example, fast forward, rewind, stop, pause, etc. in addition to normal reproduction. The time-series data processing unit 13 performs processing related to reproduction of time-series data in accordance with a user operation.

  The operation speed calculation unit 14 is a unit that calculates a user operation speed. For example, when the user's operation is an operation of moving the cursor displayed on the display unit 4 in a predetermined direction by operating the mouse, the operation speed calculation unit 14 takes the distance of the moved cursor and the movement of the cursor. From the time, the speed of movement of the cursor (an example of the speed of user operation) is calculated. It is assumed that the operation of the user whose speed is calculated by the operation speed calculation unit 14 is predetermined.

  The storage unit 2 stores UI (User Interface) data 21, neighboring time axis data 22, and time series data 23.

  The UI data 21 is data indicating a user interface screen. The UI data 21 includes data of various GUI (Graphical User Interface) components that constitute the user interface screen. Various GUI parts will be described later with reference to FIG.

  The near time axis data 22 is data indicating a near time axis displayed on the user interface screen. On the user interface screen, an entire time axis indicating the playback time of the entire time series data is displayed (details will be described later), but the neighboring time axis is displayed on the user interface screen separately from the entire time axis. Is. The near time axis is a time axis in the vicinity of the current reproduction point of the time series data, and indicates a time width expanded from the entire time axis. The time width indicated by the neighboring time axis is fixed and does not depend on the reproduction time of the entire time series data. For example, a time axis having a predetermined time width, such as 30 seconds before and after the current playback point, is displayed as this neighboring time axis. In this embodiment, a plurality of neighboring time axes having different time widths are prepared in advance. Therefore, a plurality of neighboring time axis data 22 are prepared for each neighboring time axis having a different time width. Specific examples of the plurality of neighboring time axes will be described later.

  The time series data 23 is data reproduced by the time series data processing means 13. Examples include moving image data and music data. The time series data 23 is stored in the storage unit 2 by being ripped from a portable recording medium such as a CD (Compact Disk) or a DVD (Digital Versatile Disk) or downloaded from a server on the Internet. Is. In the example of FIG. 1, the time-series data 23 is stored in the storage unit 23 in advance, but is not limited thereto. For example, the time-series data 23 may be directly input to the information processing apparatus from the outside (for example, a server or a portable recording medium on the Internet) at the time of reproduction.

  Although not shown in FIG. 1, the storage unit 2 includes a display control unit 11, a time-series data processing unit 13, and an operation speed calculation unit 14 for each user operation detected by the operation detection unit 12. Data indicating what processing operation is performed is prepared. As a result, each of the display control unit 11, the time-series data processing unit 13, and the operation speed calculation unit 14 performs the processing operation indicated by the data according to the user operation detected by the operation detection unit 12. In addition, parameters necessary for each unit to perform processing operations are also prepared in the storage unit 2.

  Next, an example of the user interface screen of the present embodiment will be described with reference to FIG.

  The user interface screen shown in FIG. 2 is displayed as follows. First, the user performs an operation for instructing reproduction of the time-series data 23 or an operation for instructing display of a user interface screen using the operation unit 3. When the operation detection unit 12 detects the operation, the display control unit 13 reads the UI data 21 from the storage unit 2 and controls the display of the display unit 4 based on the UI data 21. Thereby, the user interface screen shown in FIG. 2 is displayed on the display unit 4.

  As shown in FIG. 2, the user interface screen displayed on the display unit 4 has an image display area 30 at the top of the screen and various GUI components (31 to 37) at the bottom of the screen. A cursor 38 shown in FIG. 2 is used when a user makes a desired designation, and can be moved on the screen of the display unit 4 (including the user interface screen) according to the user's operation.

  The image display area 30 is an area where a predetermined image is displayed. For example, when the time series data is moving image data, an image of the moving image data to be reproduced is displayed in the image display area 30. In the following description, an example of time-series data will be described as moving image data.

  Below the image display area 30, an entire time axis (seek bar) 31 is displayed. As described above, the entire time axis 31 is a time axis indicating the reproduction time of the entire moving image data. The entire time axis 31 is always displayed with the same length regardless of the length of the reproduction time of the moving image data. In the entire time axis 31, the left end is the start position S of the moving image data, and the right end is the end position E of the moving image data.

  A pointer 32 is displayed on the entire time axis 31. The pointer 32 indicates the current playback point (playback location) of the moving image data, and moves on the entire time axis 31 in conjunction with the playback of the moving image data. In the case where normal playback is performed, when the video data is played back from the beginning, the pointer 32 starts moving rightward from the start position S of the video data, and when the video data is played back to the end, The movement is stopped at the end position E of the data. The pointer 32 is moved to the changed reproduction point when a change of the reproduction point is instructed by a user operation. As an example of the operation for changing the reproduction point, the user moves the cursor 38 to the pointer 32 and moves the pointer 32 to a desired reproduction point by drag and drop, or the user moves the cursor 38 to the desired reproduction point. The operation of moving to and clicking. The display control of the pointer 32 described above is performed by the display control means 11. That is, the display control unit 11 controls the display of the pointer 32 based on the processing result of the time series data processing unit 13 and the detection result of the operation detection unit 12.

  Below the entire time axis 31, a play button 33, a fast forward button 34, a rewind button 35, a stop button 36, and a pause button 37 are displayed. When the user places the cursor 38 on a desired button and performs a determination operation (for example, click), processing (playback, fast forward, rewind, stop, pause) assigned to the determined button is performed.

  Next, an example of display of the near time axis according to the present embodiment will be described with reference to FIG. FIG. 3 shows an example in which the neighborhood time axis 20a is displayed on the user interface screen shown in FIG.

  The near time axis 20a is displayed as follows. First, the user moves the cursor 38 and performs an operation for designating a desired reproduction point on the entire time axis 31. When the operation detection unit 12 detects the operation, the display control unit 13 reads the neighborhood time axis data 22 from the storage unit 2 and controls the display of the display unit 4 based on the neighborhood time axis data 22. Thereby, the near time axis 20a shown in FIG.

  The near time axis 20a displayed on the display unit 4 is displayed at a reproduction point designated by the user on the entire time axis 31, as shown in FIG. A pointer 32 is displayed at the designated playback point. The neighborhood time axis 20a shows a time width of 30 seconds before and after the current reproduction point indicated by the pointer 32 as the center (0 seconds). In order to make it easy to understand the time width of 30 seconds before and after this, in the example of FIG. 3, a scale is displayed every 10 seconds, and characters “+30 seconds” and “−30 seconds” are displayed.

  The user can move the pointer 32 on the vicinity time axis 20a and perform an operation of designating a desired reproduction point. As a result, it is possible to specify more detailed playback points than to specify playback points on the entire time axis 31. For example, the user moves the pointer 32 to the scale indicating +10 seconds by drag and drop on the vicinity time axis 20a shown in FIG. 3, or moves to the scale indicating +10 seconds. When the cursor 38 is moved and clicked, moving image data is reproduced 10 seconds after the current reproduction point.

  In the example of FIG. 3, the neighborhood time axis 20 a is displayed on the entire time axis 31, but may be displayed on an arbitrary location on the user interface screen or outside the user interface screen. Further, the user may be able to move the displayed near time axis 20a to a desired location. Further, the vicinity time axis 20a may be moved together with the pointer 32 in conjunction with the reproduction of the moving image data.

  In the example of FIG. 3, the time before and after the current playback point is set to 0 seconds is shown as the time width of the neighborhood time axis 20a, but the present invention is not limited to this. For example, the time from the beginning of the moving image data may be indicated.

  Next, an operation example of the information processing apparatus according to the present embodiment will be described with reference to FIG. The operation shown in FIG. 4 is an operation after the user interface screen of FIG. 2 is displayed.

  The user uses the operation unit 3 to move the pointer 32 on the user interface screen of FIG. 2 and perform an operation of designating a desired reproduction point on the entire time axis 31. This operation may be performed during playback of moving image data (including fast forward and rewind), or may be performed while moving image data is stopped (including pause).

  When the operation detection unit 12 detects this operation (S1), the display control unit 11 reads the near time axis data 22 from the storage unit 22 and displays the near time axis on the user interface screen based on the read time axis data 22 (S2). The state at this time is as shown in FIG. 3, for example. As shown in FIG. 3, the neighborhood time axis 20 a is displayed on the entire time axis 31 at the playback point designated by the user. The near time axis 20a shows a time width of 30 seconds before and after the current reproduction point indicated by the pointer 32 as the center (0 seconds). As described above, in the present embodiment, a plurality of neighboring time axes having different time widths are prepared in advance. However, the neighboring time axis 20a is set in advance as the first display (default neighboring time axis). Suppose that Therefore, when a predetermined reproduction point on the entire time axis 31 is designated, the display control means 11 reads out the data on the neighboring time axis 20a among the plural neighboring time axis data 22, and displays the neighboring time axis 20a. .

  If the operation detection unit 12 detects the movement of the cursor 38 after the near time axis 20a is displayed (S3 / YES), the process proceeds to S8. S8 to S10 are processing operations that characterize the present embodiment. Details thereof will be described later.

  If the operation detection unit 12 does not detect the movement of the cursor 38 (S3 / NO), but detects a display fixing operation (S4 / YES), the process proceeds to S6. The display fixing operation is an operation for the user to fix the display of the nearby time axis that is currently being displayed, and includes, for example, a click. The user performs this display fixing operation when he / she wants to perform an operation (for example, an operation for designating a reproduction point) on the near time axis currently displayed. Details of S6 will be described later.

  If the operation detection unit 12 does not detect the movement of the cursor 38 (S3 / NO) and does not detect the display fixing operation (S4 / NO), has the display control unit 11 determined that a predetermined time has elapsed? It is determined whether or not (S5). The predetermined time is not shown in FIG. 1, but is prepared in advance in the storage unit 2 as a parameter. Further, the predetermined time is preferably about several seconds, for example.

  As a result of the determination in S5, when a predetermined time has not elapsed (S5 / NO), the process returns to S3. On the other hand, if a predetermined time has elapsed as a result of S5 (S5 / YES), the process proceeds to S6.

  The display control means 11 fixes the display of the near time axis currently being displayed (S6). For example, when the neighborhood time axis currently being displayed is the neighborhood time axis 20a in FIG. 3, the time width indicated by the neighborhood time axis 20a (30 seconds before and after the current reproduction point) is not changed by fixing this display. It becomes like this.

  The operation detection unit 12 stands by until an operation for designating a desired reproduction point on the near time axis (or on the entire time axis 31) is detected (S7). Thereafter, if the operation detecting unit 12 detects an operation for designating a predetermined reproduction point on the nearby time axis (or on the entire time axis 31) and an operation for instructing execution of reproduction of moving image data, the display control unit 11 Moves the pointer 32 to the designated reproduction point, and the time-series data processing means 13 starts reproduction of the moving image data from the designated reproduction point.

  Here, the details of the processing operations of S8 to S10, which are features of the present embodiment, will be described below.

  After the neighboring time axis 20a is displayed (S2), when the user wants to change the time width indicated by the neighboring time axis 20a to another one, the user moves the cursor 38 in an arbitrary direction by an arbitrary distance (hereinafter referred to as the time width 20a) Cursor movement operation). This cursor movement operation is predetermined in the storage unit 2 as an operation whose speed is calculated by the operation speed calculation unit 14. When this cursor movement operation is performed, the cursor 38 may be anywhere on the screen of the display unit 4 (it is not necessary to be on the user interface screen). Here, as an example, it is assumed that the cursor 38 is moved about 1 cm in the right direction parallel to the adjacent time axis 20a as indicated by an arrow a in FIG.

  The operation detection unit 12 detects the movement of the cursor 38 according to the cursor movement operation (S3 / YES). At this time, the operation detection means 12 detects the distance that the cursor 38 has moved (hereinafter referred to as the movement distance) and the time taken for the movement of the cursor 38 (hereinafter referred to as the movement time).

  The operation speed calculation means 14 moves the cursor 38 based on the movement distance and the movement time detected by the operation detection means 12 because the cursor movement operation detected by the operation detection means 12 is an operation to be calculated. The speed is calculated (S8).

  Based on the moving speed of the cursor 38 calculated by the operation speed calculating means 14, the display control means 11 searches for the nearby time axis data 22 from the storage unit 2 (S9).

  Here, a specific example of the neighborhood time axis data 22 prepared in the storage unit 2 will be described. As described above, a plurality of neighborhood time axis data 22 are prepared for each neighborhood time axis having a different time width. For example, the data of the neighborhood time axis 20a indicating the time width of 30 seconds before and after the current playback point as the center (0 seconds), the neighborhood time axis indicating the time width of 1 minute before and after the current playback point as the center (0 seconds) There are three types of data, 20b data and data on the near time axis 20c indicating the time width of 10 seconds before and after the current reproduction point as the center (0 seconds). These three types of data are respectively associated with the moving speed of the cursor 38 in the data table shown in FIG. That is, the data on the neighborhood time axis 20a is linked to the moving speed of the cursor 38 “over 150 pixels / second and 300 pixels / second or less”. The data on the neighborhood time axis 20a is set as a default. In addition, the data of the neighborhood time axis 20b is linked to the moving speed of the cursor 38 “exceeding 300 pixels / second”. In addition, the data on the neighborhood time axis 20c is associated with the moving speed of the cursor 38 “exceeding 0 pixel / second and not more than 150 pixel / second”. As described above, the plurality of adjacent time axis data 22 has a larger (wider) time width as the moving speed of the cursor 38 is faster (larger). In FIG. 5, the plurality of neighboring time axis data 22 may be linked so that the time width becomes larger (wider) as the moving speed of the cursor 38 is slower (smaller). In the present embodiment, the default example is the data on the neighborhood time axis 20a, but the data on the neighborhood time axis 20b or 20c may be used.

  The data table shown in FIG. 5A is used when the display control means 11 searches the near time axis data 22 in S9. Although not shown in FIG. 1, the data table shown in FIG. 5A is prepared in advance for each screen resolution in the storage unit 2. FIG. 5A is a data table when the screen resolution is 1600 × 1024 pixels. As another example, as shown in FIG. 5B, a data table for a screen resolution of 800 × 600 pixels may be prepared. Note that the data table shown in FIG. 5 may be prepared according to the size of the screen, or may be arbitrarily customized by the user.

  For this reason, in S9, the display control unit 11 refers to the data table shown in FIG. 5A, for example, and the vicinity associated with the moving speed of the cursor 38 calculated by the operation speed calculating unit 14 The time axis data 22 (any one of the three types) is searched.

  The display control unit 11 reads the searched near time axis data 22 from the storage unit 2 and controls display based on the read near time axis data 22. That is, the display control means 11 changes the display from the currently displayed neighborhood time axis (for example, neighborhood time axis 20a) to the neighborhood time axis indicated by the neighborhood time axis data 22 read this time (S10).

  For example, when the calculated movement speed of the cursor 38 exceeds 300 pixels / second (when the movement speed is high), the display is changed based on the data on the nearby time axis 20b, as shown in FIG. That is, the display is changed from the neighborhood time axis (for example, neighborhood time axis 20a) currently being displayed to the neighborhood time axis 20b. The neighborhood time axis 20b shows a time width of 1 minute before and after the current reproduction point indicated by the pointer 32 as the center (0 seconds). Therefore, when the user wants to change the time width of the nearby time axis to a larger (wide) time width, the user may perform the cursor movement operation with an awareness that the movement of the cursor 38 is faster. In addition, although the number of scales is displayed on the neighborhood time axis 20b shown in FIG. 6 as compared with the neighborhood time axis 20a, the same number of scales as the neighborhood time axis 20a may be displayed. That is, on the time axis before and after the change, the display of characters indicating the time (for example, display of “−30 seconds” and “+30 seconds”) may be changed without changing the number of scales. .

  Further, for example, when the calculated movement speed of the cursor 38 exceeds 0 pixel / second and is 150 pixel / second or less (when the movement speed is slow), the display is changed based on the data of the neighboring time axis 20c. As shown in FIG. In other words, the display is changed from the neighborhood time axis (for example, neighborhood time axis 20a) currently being displayed to the neighborhood time axis 20c. The neighborhood time axis 20c shows a time width of 10 seconds before and after the current reproduction point indicated by the pointer 32 as the center (0 seconds). Therefore, when the user wants to change the time width of the neighborhood time axis to a small (narrow) time width, the user may perform the cursor movement operation with the consciousness that the movement of the cursor 38 is delayed. In addition, in the vicinity time axis | shaft 20c shown in FIG. 7, it was set as the example displayed fewer numbers of scales compared with the vicinity time axis | shaft 20a, However, The number of scales same as the vicinity time axis | shaft 20a may be displayed. That is, on the time axis before and after the change, the display of characters indicating the time (for example, display of “−30 seconds” and “+30 seconds”) may be changed without changing the number of scales. .

  After the display of the near time axis is changed in S10, the process proceeds to S4. Here, the user performs the above-described display fixing operation if the changed neighborhood time axis is acceptable (S4 / YES). Examples of the display fixing operation at this time include an operation of stopping the movement of the cursor performed to change the display of the nearby time axis, or an operation of performing a click. Subsequent S6 to S7 have already been described, and a description thereof is omitted here. On the other hand, when the user wants to further change the neighborhood time axis after the change, the above-described cursor movement operation is performed again within a predetermined time (S4 / NO, S5 / NO, S3 / YES). The subsequent operation is as described above.

  In the above description, the cursor movement operation is taken as an example of the user operation detected in S3, but is not limited to this. That is, the user's operation detected in S3 may be anything that can calculate (measure) the operation speed.

  Further, in the above description, three types (20a, 20b, 20c) of the neighboring time axes having different time widths are used, but two or more types may be used. However, the larger one is preferable.

  In the above description, the display of the near time axis is changed according to the moving speed of the cursor. However, the display of the near time axis may be changed according to the moving distance of the cursor. In this case, as shown in FIG. 8, a plurality of neighboring time axis data 22 having different time widths are associated with each movement distance of the cursor. The operation is basically the same as that described with reference to FIG. 4, but S8 and S9 in FIG. 4 are different. That is, when the movement of the cursor is detected (S3 / YES), the operation speed calculation means 14 does not calculate the movement speed of the cursor 38 (S8 is omitted), and the display control means 11 performs the operation detection means. On the basis of the movement distance of the cursor 38 detected by 12, the vicinity time axis data 22 is searched with reference to the data table of FIG. 8 (S 9). In the data table of FIG. 8, the plurality of neighboring time axis data 22 is an example in which the time width becomes larger (wider) as the movement distance of the cursor 38 becomes longer (larger), but the movement distance of the cursor 38 becomes shorter. The smaller (smaller), the longer the time width may be.

  As described above, according to the present embodiment, the user can perform an intuitive operation such as movement of the cursor by changing the speed or changing the movement distance of the cursor, thereby facilitating the time width indicated by the nearby time axis. Can be selected. That is, in the present embodiment, in order to specify a desired time width after performing a stepwise operation in the invention of Patent Document 1, that is, an operation for calling (displaying) a time width option on the user interface screen. Therefore, an operation for selecting a desired time width is not complicated for the user. In particular, the present embodiment is effective when the user frequently changes the time width (because it is not necessary to repeat the stepwise operation).

  Further, for example, as shown in FIG. 3 of Patent Document 1, in the method of displaying a plurality of buttons corresponding to each time width as options, there is a limit to the number of options that can be displayed on the user interface screen. It will be limited. On the other hand, according to the present embodiment, it is not necessary to display the time width options on the user interface screen, so that time time options can be prepared in a wide range.

  Further, in the method of displaying time width options using buttons and lists as in Patent Document 1, when the number of options is wide, the displayed options increase. It becomes difficult to find out. On the other hand, according to the present embodiment, it is not necessary to display time width options on the user interface screen, so even if a wide range of time width options are prepared, it is difficult for the user to find a desired one. That's not true.

  Further, for example, as shown in FIG. 3 of Patent Document 1, in the method of displaying a plurality of buttons corresponding to each time width as options, the display of these buttons occupies a space on the user interface screen. On the other hand, according to the present embodiment, since it is not necessary to display the time width options on the user interface screen, the layout on the user interface screen is simplified or occupied by the display of the button. The space can be used for another display.

  As mentioned above, although embodiment of this invention was described, it is not limited to the said embodiment, A various deformation | transformation is possible in the range which does not deviate from the summary.

  For example, the operation in the above-described embodiment can be executed by hardware, software, or a combined configuration of both.

  When executing processing by software, a program in which a processing sequence is recorded may be installed and executed in a memory in a computer incorporated in dedicated hardware. Or you may install and run a program in the general purpose computer which can perform various processes.

  For example, the program can be recorded in advance on a hard disk or a ROM (Read Only Memory) as a recording medium. Alternatively, the program is stored on a removable recording medium such as a CD-ROM (Compact Disc Read Only Memory), an MO (Magneto Optical) disc, a DVD (Digital Versatile Disc), a USB (Universal Serial Bus) memory, a magnetic disc, and a semiconductor memory. It is possible to store (record) temporarily or permanently. Such a removable recording medium can be provided as so-called package software.

  The program may be wirelessly transferred from the download site to the computer in addition to being installed on the computer from the removable recording medium as described above. Or you may wire-transfer to a computer via networks, such as LAN (Local Area Network) and the internet. The computer can receive the transferred program and install it on a recording medium such as a built-in hard disk.

  In addition to being executed in time series in accordance with the processing operations described in the above embodiment, the processing capability of the apparatus that executes the processing, or a configuration to execute in parallel or individually as necessary Is also possible.
