  The seek bar 801 is provided with an icon 801a that moves on the seek bar 801 as the content is reproduced, and the seek bar 802 is provided with an icon 802a that moves on the seek bar 802 as the content is reproduced.

  As shown in FIGS. 15A and 15B, generally, the lengths of the seek bars 801 and 802 are fixed regardless of the length of the scale of the content. For this reason, the value per one scale of the seek bars 801 and 802 increases or decreases depending on the length of the scale of the content. As a result, the longer the content to be reproduced, the more difficult it is to move the icon and specify the position of the content in the reproduction time in detail.

  For this reason, in order to improve user operability, Patent Documents 1 and 2 disclose the following techniques.

  FIG. 16A is a diagram illustrating a seek bar disclosed in Patent Document 1. FIG. As shown in FIG. 16A, the seek bar 803 is provided with an icon 803a that moves according to the reproduction of the content.

Of the plurality of divided sections 803b, 803c, and 803d, the section 803c in which the icon 803a is arranged is enlarged and displayed. As a result, the user can finely specify the position of the time zone included in the section 803c in the content playback time by moving the icon 803a.

  FIG. 16B is a diagram illustrating a seek bar of Patent Document 2. As shown in FIG. 16B, the seek bar 804 is provided with an icon 804a that moves in accordance with the reproduction of the content.

  The seek bar 804 has the position of the current icon 804a as the origin, and the left end of the seek bar 804 (position where “0:00” is displayed), which is a position on the time axis corresponding to the playback start time of the content from the origin. And, from the origin to the right end of the seek bar 804 (the position where “60:00” is displayed), which is the position on the time axis corresponding to the playback end time of the content, is connected with an exponential curve.

  In this way, in Patent Document 2, the scale value for skipping a scene is accelerated in accordance with the distance from the origin in accordance with this curve. Thereby, in the vicinity section 804b where the icon 804a is arranged, the position of the icon 804a on the time axis can be set finely, and the moving image can be quickly skipped to a distant scene.

In addition, the length of the reproduction time of content associated with the unit length of the seek bar 10 may be referred to as granularity.

(Description of the configuration of the image display device 1)
Next, the configuration of the image display apparatus 1 will be described with reference to FIG. FIG. 1 is a functional block diagram showing the configuration of the image display device 1.

  As shown in FIG. 1, the image display apparatus 1 includes a display unit 2, an input unit 3, a speaker 4, a storage unit 20, and a control unit 30, which are connected to each other.

  The storage unit 20 includes a ROM 21 and a RAM 22.

  The ROM 21 is a storage unit that stores programs and various data necessary for operating the image display apparatus 1.

  The ROM 21 stores various programs for reproducing or recording a moving image application, a still image application, an audio application, or the like.

  The RAM 22 is a storage unit for temporarily storing information necessary for the operation of the image display device 1. The RAM 22 appropriately stores data read from the ROM 21.

  In the present embodiment, when the image display device 1 is playing back content, the RAM 22 displays content total playback time information 22a indicating the total playback time of the content being played back, and the time axis of the content. The seek bar display information 22b for displaying the seek bar 10 is stored.

  The seek bar display information 22b includes content reproduction position information 22c, magnification value information 22d, and the like.

  The content reproduction position information 22c is information for displaying the icon 10a on the seek bar 10. The content reproduction position information 22c represents the reproduction position on the time axis of the content currently being reproduced.

  In the magnification value information 22d, a plurality of predetermined times and magnification values for expanding the time axis of the content being reproduced are registered in association with each other.

  An example of the magnification value information 22d is shown in FIGS.

  FIG. 13 shows the configuration of the magnification value information 22d when the magnification on the time axis of the content is assigned as the magnification value.

  FIG. 14 shows the configuration of the magnification value information 22d when the reproduction time per division of the seek bar 10 is assigned as the magnification value.

  The predetermined time of the magnification value information 22d is a time for the input information determination unit 33 (described later) to determine whether or not the user has long pressed the icon 10a.

  In the magnification value information 22d, a plurality of predetermined times are registered so that the value increases stepwise. As an example, the predetermined time is registered as 0 seconds, 1 second, 3 seconds, 5, seconds, 7 seconds, and 9 seconds.

  The magnification value of the magnification value information 22d is a magnification for enlarging the time axis of the content being reproduced. In the magnification value information 22d, a plurality of magnification values are registered in association with each predetermined time so that the value increases stepwise.

  As an example, in FIG. 13, the magnification values are registered as 1 ×, 2 ×, 10 ×, 20 ×, 60 ×, and 120 ×. A magnification value of 1 is associated with a predetermined time of 0 seconds, a magnification value of 2 is associated with a predetermined time of 1 second, a magnification value of 10 is associated with a predetermined time of 3 seconds, and a magnification value 20 times is associated with a predetermined time of 5 seconds, a magnification value of 60 is associated with a predetermined time of 7 seconds, and a magnification value of 120 is associated with a predetermined time of 9 seconds.

  Alternatively, as shown in FIG. 14, as a magnification value, 10 minutes, 5 minutes, 1 minute, 30 seconds, 10 seconds, and 5 seconds may be registered, and for example, a fixed time may be associated with the section 10z. .

  A magnification value of 10 minutes is associated with a predetermined time of 0 seconds, a magnification value of 5 minutes is associated with a predetermined time of 1 second, a magnification value of 1 minute is associated with a predetermined time of 3 seconds, and a magnification value 30 seconds is associated with a predetermined time of 5 seconds, a magnification value of 10 seconds is associated with a predetermined time of 7 seconds, and a magnification value of 5 seconds is associated with a predetermined time of 9 seconds.

  13 and 14, the magnification value associated with the predetermined time of 0 seconds is an initial value. In some cases, the magnification value associated with the shortest predetermined time value (ie, 0 seconds) is referred to as a lower limit, and the magnification value associated with the longest predetermined time value (9 seconds) is referred to as an upper limit. is there.

  13 or 14, as shown in FIG. 13, in the method of relatively expanding the length of the content, as the length of the content is increased, the user is required to expand the axis. The long press time of the is prolonged, the convenience is impaired.

  For this reason, when the length of the scale of the content is long, the method of setting the magnification value as shown in FIG. 14 in which the reproduction time of one scale is a fixed length is preferable. This is because the long press time of the user can be reduced, leading to an improvement in convenience.

  The control unit 30 is a control unit for controlling and driving the image display apparatus 1 in an integrated manner. The control unit 30 includes one or a plurality of CPUs. The control unit 30 acquires a program from the ROM 21 or the RAM 22 and controls the driving of the image display device 1 by executing the acquired program or the like. Further, the control unit 30 appropriately stores information acquired from the ROM 21 in the RAM 22.

  The control unit 30 has a content control unit 31.

  The content control unit 31 reproduces moving image content, still image content, audio content, or the like in response to a user request.

  When the control unit 30 acquires content reproduction instruction information from the user through the input unit 3, the content control unit 31 uses the ROM 21 or RAM for content reproduction to reproduce the content indicated by the acquired reproduction instruction information. Load and execute the program. Accordingly, the content control unit 31 reproduces various contents in response to a user's reproduction request such as moving image content, still image content, or audio content.

  The content control unit 31 includes a seek bar control unit 32. The seek bar control unit 32 includes an input information determination unit 33 and a magnification value change unit 34.

  When the content control unit 31 reproduces the content, the seek bar control unit 32 causes the display unit 2 to display the seek bar 10 indicating the reproduction state of the content, the icon 10a, the content leading end value 11b, the terminal end value 11c, and the like.

  When the content control unit 31 reads a content playback program from the ROM 21 or RAM 22, the seek bar control unit 32 reads content total playback time information 22a indicating the total playback time of the content to be played back and seek bar display information 22b. The seek bar control unit 32 displays the seek bar 10, the icon 10a, the content leading value 11b, the terminal value 11c, and the like based on the total content playback time information 22a read from the RAM 22 and the seek bar display information 22b. Is output to the display unit 2. Accordingly, the display unit 2 displays the seek bar 10, the icon 10a, the content tip value 11b, the terminal value 11c, and the like.

  The input information determination unit 33 determines whether or not the position of the finger (object) detected by the input unit 3 is the display position of the icon 10a and the position of the finger is fixed for a predetermined time.

  The input information determination unit 33 determines whether or not the user has long-pressed the icon 10a at every predetermined time registered in the magnification value information 22d, or whether or not the long-pressed finger has been released for a certain time or more. To determine.

  The input information determination unit 33 acquires information indicating that the user has touched the icon 10a with the finger through the input unit 3, and when the position is fixed, the input information determination unit 33 displays the magnification value information 22d. By determining step by step whether or not each registered predetermined time has been reached, it is determined for each step whether or not the user has long pressed the icon 10a.

  The magnification value changing unit 34 acquires, from the magnification value information 22d, a magnification value associated with a predetermined time determined by the input information determining unit 33 to be held down by the user. Then, with the magnification value acquired by the magnification value changing unit 34, the seek bar control unit 32 enlarges the time axis of the content being reproduced, assigns it to the seek bar 10, and causes the display unit 2 to display it.

(Operation method and display screen of seek bar 10)
Next, the operation method and display screen of the seek bar 10 will be described.

  3A shows the seek bar 10 before the icon 10a is pressed for 1 second, and FIG. 3B shows the seek bar 10 after the icon 10a is pressed for 1 second.

  4A shows the seek bar 10 before the icon 10a is pressed for 3 seconds, and FIG. 4B shows the seek bar 10 after the icon 10a is pressed for 3 seconds.

  As an example, a case will be described in which the image display device 1 reproduces content having a total reproduction time of 60 minutes. The seek bar 10 is provided with a scale z divided into six parts, and as an initial value, the playback time of the content associated with the section 10z of one scale is 10 minutes.

  Here, it is assumed that the RAM 22 stores the magnification value information 22d shown in FIG.

  That is, it is assumed that the section 10z has a fixed time length in steps and the assigned playback time becomes shorter in correspondence with the long press time of the user icon 10a.

  When the content control unit 31 acquires content playback instruction information input from the input unit 3 from the user, for example, the content control unit 31 plays back content with a total playback time of 60 minutes.

  First, a case where the magnification value of the content reproduction time axis is changed in one stage will be described.

  As shown in FIG. 3A, the seek bar control unit 32 displays the time “0:00” as the leading value 11b of the currently played content on the display unit 2 in the vicinity of the left end 10b of the seek bar 10. In the vicinity of the right end 10c of the seek bar 10, the time “66:00” as the content end value 11c is displayed.

  Then, in order to reduce the granularity of the seek bar 10, the user long presses the icon 10a. As an example, the user presses and holds the 1-second icon 10a. Then, the input information determination unit 33 detects from the information input through the input unit 3 that the user has pressed the icon 10a for 1 second.

  Then, the magnification value changing unit 34 refers to the magnification value information 22d in the RAM 22 and acquires the magnification value 5 minutes associated with the predetermined time 1 second.

  As a result, as shown in FIG. 3B, the seek bar control unit 32 changes the allocated playback time of the section 10z from 10 minutes to 5 minutes, and displays the seek bar 10, the tip value 11b, and the end value 11c. The display unit 2 is changed and displayed.

  The display unit 2 displays the time “0:00” as the leading end value 11b of the content in the vicinity of the left end 10b after reducing the granularity of the seek bar 10, and the total playback time of the content in the vicinity of the right end 10c. The median time “30:00” is displayed.

  As described above, the seek bar control unit 32 assigns the length of the content playback time of 60 minutes from the left end 10b to the right end 10c of the seek bar 10, and the same is achieved by detecting the user's long press for 1 second. From the left end 10b to the right end 10c of the length seek bar 10, half the content playback time length of 30 minutes is assigned and displayed on the display unit 2. In this way, the seek bar control unit 32 reduces the granularity of the seek bar 10. That is, the content playback time axis is enlarged and displayed.

  Here, when the seek time control unit 32 expands or reduces the playback time axis of the content and assigns it to the seek bar 10, the icon 10a on the seek bar 10 does not move before and after the time axis is expanded or reduced. It is preferable to assign a time axis to the seek bar 10 with the position of 10a as the origin. This is because the position of the icon 10a does not move before and after the time axis is enlarged or reduced, thereby preventing usability deterioration.

  When the seek bar control unit 32 detects that the user has removed his / her finger from the icon 10a for a predetermined time (for example, 1 second), the content playback time allocation indicated by the section 10z of the seek bar 10 is set to the initial value of 10 minutes. The display of the seek bar 10, the tip value 11b, and the end value 11c is changed and displayed on the display unit 2.

  That is, the display unit 2 displays the time “0:00” as the leading end value 11b of the currently reproduced content, and the time “60: as the terminal end value 11c of the content is near the right end 10c of the seek bar 10. 00 ”is displayed.

  As described above, in the image display device 1, the input information determination unit 33 detects that the finger position detected by the input unit 3 is the display position of the icon 10a, and the finger position is fixed for a predetermined time (that is, the user selects the icon If it is determined that the user presses 10a for a long time), the seek bar control unit 32 sets the magnification value (for example, 5 minutes) registered in association with a predetermined time (for example, 1 second). The time axis is expanded and assigned to each section 10z of the seek bar 10.

  For this reason, the user can quickly move a long distance before expanding the time axis. Further, the time axis of the content assigned to the seek bar 10 can be expanded simply by bringing the user into contact with the icon 10a and fixing the touched position for a predetermined time (for example, 1 second).

  This allows the user to make fine settings for the playback position. As a result, according to the image display device 1, even if the content has a long total playback time, the playback position of the content can be set finely with a simple operation, and thus the convenience improvement effect can be obtained.

  Next, the case where the magnification value of the content reproduction time axis is changed in two steps will be described.

  As shown in FIG. 4A, the seek bar control unit 32 displays the time “0:00” as the leading value 11b of the currently played content on the display unit 2 in the vicinity of the left end 10b of the seek bar 10. In the vicinity of the right end 10c of the seek bar 10, the time “66:00” as the content end value 11c is displayed.

  Then, as shown in FIGS. 4A and 4B, it is assumed that the user presses the icon 10a and the user long presses the 3-second icon 10a in order to reduce the granularity of the seek bar 10 from the original state.

  Then, after the elapse of 1 second, the seek bar control unit 32 first sets the interval so that the magnification value is 5 minutes associated with the predetermined time 1 second, as shown in FIG. A reproduction time of 5 minutes is assigned to 10z, and the display of the seek bar 10, the tip value 11b, and the end value 11c after the assignment is changed and displayed on the display unit 2.

  Then, after 3 seconds have passed, the input information determination unit 33 detects that the icon 10a has been pressed for 3 seconds by the information input through the input unit 3.

  Then, the magnification value changing unit 34 refers to the magnification value information 22d in the RAM 22, and acquires the magnification value 1 minute associated with the predetermined time 3 seconds.

  As a result, as shown in FIG. 4B, the seek bar control unit 32 changes the allocated playback time of the section 10z from 5 minutes to 1 minute, and displays the seek bar 10, the tip value 11b, and the end value 11c. The display unit 2 is changed and displayed.

  The display unit 2 displays the time “0:00” as the leading end value 11b of the content in the vicinity of the left end 10b after reducing the granularity of the seek bar 10, and the total playback time of the content in the vicinity of the right end 10c. “6:00” which is a value of 1/10 is displayed.

  As described above, the seek bar control unit 32 detects the user's long press of 3 seconds when the content playback time length of 60 minutes is allocated from the left end 10b to the right end 10c of the seek bar 10 in the initial state. Thus, the length of the content playback time of 6 minutes, which is 1/10, is assigned to the display unit 2 from the left end 10b to the right end 10c of the seek bar 10 having the same length. In this way, the seek bar control unit 32 reduces the granularity of the seek bar 10. That is, the content playback time axis is enlarged and displayed.

  When the seek bar control unit 32 detects that the user has removed his / her finger from the icon 10a for a predetermined time (for example, 1 second), the allocation of the content playback time indicated by the section 10z of the seek bar 10 is first performed as shown in FIG. The display of the seek bar 10, the tip value 11b, and the terminal value 11c is changed to the display unit 2 and displayed.

  When the seek bar control unit 32 further detects that the user has removed his / her finger from the icon 10a for a predetermined time (for example, 1 second), the allocation of the content playback time indicated by the section 10z of the seek bar 10 is 10 in the initial state. Returning to minutes, the display of the seek bar 10, the tip value 11b, and the terminal value 11c is changed and displayed on the display unit 2.

  That is, the display unit 2 displays the time “0:00” as the leading end value 11b of the currently reproduced content, and the time “60: as the terminal end value 11c of the content is near the right end 10c of the seek bar 10. 00 ”is displayed.

  The same applies when the time axis of the content playback time is changed in three or more stages from the initial state. The content reproduction time axis is enlarged by the predetermined time registered in the magnification value information 22d and the number of magnification values (number of stages) registered in association with the predetermined time, and assigned to the seek bar 10 for display. It is possible.

  As described above, in the image display device 1, the input information determination unit 33 determines whether or not the icon 10a is pressed and held every time registered in the magnification value information 22d, and the seek bar control unit 32 For each predetermined time determined by the input information determination unit 33 that the icon 10a is pressed and held, the magnification value associated with each of the predetermined time is acquired from the magnification value information 22d of the RAM 22. Then, the seek bar control unit 32 expands the time axis of the content and assigns it to the seek bar 10 for each acquired magnification value.

  Thereby, the user can expand the allocation of the content time axis to the seek bar 10 in stages only by changing the long press time of the icon 10a. For this reason, it is possible to switch between quick movement of the content reproduction position and fine position setting with a simple operation. As a result, convenience can be improved.

  Specifically, the seek bar control unit 32 refers to the magnification value information 22d, and when the input information determination unit 33 determines that the long press time of the icon 10a by the user is 5 seconds, the seek bar control unit 32 When the input information determination unit 33 determines that the long pressing time of the icon 10a by the user is 7 seconds, the seek bar control unit 32 allocates the reproduction time of 10 seconds to the section 10z, and the user icon When the input information determination unit 33 determines that the long press time of 10a is 9 seconds, the seek bar control unit 32 allocates a playback time of 5 seconds to the section 10z. Then, the seek bar 10, the tip value 11b, and the terminal value 11c are displayed on the display unit 2, respectively.

  In this way, the seek bar control unit 32 reduces the granularity of the seek bar 10 in multiple stages in accordance with the long press time length of the user icon 10a, that is, the time axis of the content playback time is set in multiple stages. To expand and assign.

  As a result, the user can change the granularity of the seek bar 10 simply by changing the contact time of the finger with the icon 10a, so that the reproduction position of the content can be quickly moved to a distant place. At the same time, fine position setting is possible. Furthermore, the user's operation only changes the contact time of the finger to the icon 10a between the case where the content reproduction position is moved quickly and the case where the position is finely set, so that the operability is improved. Therefore, it is possible to obtain the image display device 1 that is highly convenient for the user.

  Conversely, when the seek bar control unit 32 expands the time axis of the content and assigns it to the seek bar 10, the user releases the icon 10a and the long press is released, so that the input unit 3 Is not detected for a certain period of time (for example, 1 second), the seek bar control unit 32 sets the time axis of the content that has been expanded and allocated to the passage of a certain period of time (for example, 1 second). To the seek bar 10.

  Thereby, the user can reduce the allocation of the content time axis to the seek bar 10 in stages only by changing the time for releasing the long press of the finger. For this reason, it is possible to switch between quick movement of the content reproduction position and fine position setting with a simple operation, and a highly convenient position input apparatus can be obtained.

  Alternatively, when the seek bar control unit 32 expands the time axis of the content and assigns it to the seek bar 10 instead of reducing in stages, the user releases the icon 10a and the long press is released, When the input unit 3 does not detect information indicating that the user is long-pressed for a certain period of time (for example, 1 second), the seek bar control unit 32 sets the time axis of the content that has been enlarged and assigned at once. It may be reduced and assigned to the seek bar 10.

(About the configuration for recognizing the granularity of seek bar 10)
If the allocation of the playback time to the seek bar 10 is changed in multiple stages, the user may have difficulty grasping the current stage.

  For this reason, as shown in FIGS. 5 to 7, when the display mode of the seek bar 10 is changed or the icon 10 a is moved according to the magnification factor of the time axis of the content playback time assigned to the seek bar 10. The sound may be changed.

  FIG. 5 is a diagram illustrating the seek bar 10 having different shades depending on the particle size.

  In (a) to (f) of FIG. 5, the color density of the seek bar 10 is made lighter as the level increases (the particle size becomes smaller).

  FIG. 5A shows the state of the seek bar 10 in the normal display state. The seek bar 10 in FIG. 5A has a content playback time length of 10 minutes per section 10z, displays time “0:00” near the left end 10b, and time “60:00” near the right end 10c. it's shown.

  FIG. 5B shows the state of the seek bar 10 in a display state in which the granularity is reduced by one step from the normal display state. The seek bar 10 in FIG. 5B has a content playback time length of 5 minutes per section 10z, displays time “0:00” near the left end 10b, and time “30:00” near the right end 10c. it's shown. The color density of the seek bar 10 shown in FIG. 5B is lighter than the color density of the seek bar 10 shown in FIG.

  FIG. 5C shows the state of the seek bar 10 in a display state in which the granularity is reduced by two steps from the normal display state. The seek bar 10 in FIG. 5C has a content playback time length of 1 minute per section 10z, displays the time “0:00” in the vicinity of the left end 10b, and displays the time “6:00” in the vicinity of the right end 10c. it's shown. The color density of the seek bar 10 shown in (c) of FIG. 5 is further lighter than the color density of the seek bar 10 shown in (b) of FIG.

  FIG. 5D shows the state of the seek bar 10 in a display state in which the granularity is reduced by three levels from the normal display state. The seek bar 10 in FIG. 5D has a content playback time length of 30 seconds per section 10z, displays the time “0:00” in the vicinity of the left end 10b, and displays the time “3:00” in the vicinity of the right end 10c. it's shown. The color density of the seek bar 10 shown in (d) of FIG. 5 is further lighter than the color density of the seek bar 10 shown in (c) of FIG.

  (E) of FIG. 5 represents the state of the seek bar 10 in the display state in which the granularity is reduced by four steps from the normal display state. The seek bar 10 in FIG. 5E has a content playback time length of 10 seconds per section 10z, displays the time “0:00” in the vicinity of the left end 10b, and displays the time “1:00” in the vicinity of the right end 10c. it's shown. The color density of the seek bar 10 shown in (e) of FIG. 5 is further lighter than the color density of the seek bar 10 shown in (d) of FIG.

  FIG. 5F shows the state of the seek bar 10 in a display state in which the granularity is reduced by five levels from the normal display state. The seek bar 10 in FIG. 5F has a content playback time length of 5 seconds per section 10z, displays the time “0:00” in the vicinity of the left end 10b, and displays the time “0:30” in the vicinity of the right end 10c. it's shown. The color density of the seek bar 10 shown in (f) of FIG. 5 is further lighter than the color density of the seek bar 10 shown in (e) of FIG.

  Thus, the seek bar control unit 32 converts the color density of the seek bar 10 according to the granularity (enlargement of the playback time axis of the content) and displays it on the display unit 2, so that the user can now display the seek bar 10. It is possible to visually grasp the granularity of the image, that is, the stage of the enlargement ratio. For this reason, user operability can be improved.

  FIG. 6 is a diagram illustrating an operation of sliding the content within the total playback time when the granularity of the seek bar 10 is reduced.

  As a result of reducing the granularity per section 10 z of the seek bar 10, all the scales of the content being played cannot fit within the seek bar 10. For this reason, the seek bar control unit 32 may display the following icons on the display unit 2 in the vicinity of the seek bar 10 to operate the seek bar 10.

  Further, the seek bar control unit 32 may change the color of the seek bar 10 according to the stage, not the shading of the seek bar 10.

  FIG. 6 is a diagram illustrating the seek bar 10 having different colors depending on the particle size.

  FIG. 6A shows a state of the seek bar 10 in a normal display state in which the reproduction time per section 10z is 10 minutes. As shown to (a) of FIG. 6, the seek bar control part 32 displays the seek bar 10 in red in an initial state.

As shown in FIG. 6B, the seek bar control unit 32 displays the seek bar 10 with the one-step granularity reduced in orange.

  FIG. 6C shows a state of the seek bar 10 in a display state in which the reproduction time per section 10z is 1 minute and the granularity is reduced in two steps from the normal display state. As shown in FIG. 6C, the seek bar control unit 32 displays the seek bar 10 with the two-step granularity reduced in yellow.

  FIG. 6D shows the state of the seek bar 10 in a display state in which the reproduction time per section 10z is 30 seconds and the granularity is reduced in three stages from the normal display state. As shown in FIG. 6D, the seek bar control unit 32 displays the seek bar 10 with the three-step granularity reduced in green.

  FIG. 6 (e) shows the state of the seek bar 10 in a display state in which the reproduction time per section 10z is 10 seconds and the granularity is reduced in four stages from the normal display state. As shown in FIG. 6E, the seek bar control unit 32 displays the seek bar 10 with the four-step granularity reduced in light blue.

  FIG. 6F shows the state of the seek bar 10 in the display state in which the reproduction time per section 10z is 5 seconds and the granularity is reduced in five steps from the normal display state. As shown in (f) of FIG. 6, the seek bar control unit 32 displays the seek bar 10 with the five-step granularity reduced in blue.

  Alternatively, the seek bar control unit 32 may change the thickness of the seek bar 10 in accordance with the stage, not the change in shade or color of the seek bar 10.

  FIG. 7 is a diagram illustrating the seek bar 10 having different colors depending on the particle size.

  FIG. 7A shows a state of the seek bar 10 in a normal display state in which the reproduction time per section 10z is 10 minutes. As shown in FIG. 7A, the seek bar control unit 32 displays the seek bar 10 with the narrowest width in the initial state.

  FIG. 7B shows the state of the seek bar 10 in a display state in which the reproduction time per section 10z is 5 minutes and the granularity is reduced by one step from the normal display state. As shown in FIG. 7B, the seek bar control unit 32 displays the seek bar 10 having a smaller one-step granularity with a wider width than the seek bar 10 shown in FIG.

  FIG. 7C shows a state of the seek bar 10 in a display state in which the reproduction time per section 10z is 1 minute and the granularity is reduced in two steps from the normal display state. As shown in FIG. 7C, the seek bar control unit 32 displays the seek bar 10 having a smaller two-step granularity with a wider width than the seek bar 10 shown in FIG. 7B.

  FIG. 7D shows a state of the seek bar 10 in a display state in which the reproduction time per section 10z is 30 seconds and the granularity is reduced in three stages from the normal display state. As shown in FIG. 7D, the seek bar control unit 32 displays the seek bar 10 with the three-step granularity made smaller in width than the seek bar 10 shown in FIG.

  FIG. 7E shows the state of the seek bar 10 in a display state in which the reproduction time per section 10z is 10 seconds and the granularity is reduced in four stages from the normal display state. As shown in FIG. 7E, the seek bar control unit 32 displays the seek bar 10 with the four-step granularity smaller than the seek bar 10 shown in FIG. 7D.

  FIG. 7 (f) shows the state of the seek bar 10 in a display state in which the reproduction time per section 10z is 5 seconds and the granularity is reduced by five levels from the normal display state. As shown in FIG. 7 (f), the seek bar control unit 32 displays the seek bar 10 with the five-step granularity smaller than the seek bar 10 shown in FIG. 7 (e).

  As described with reference to FIGS. 5 to 7, the user can visually recognize the currently set granularity by changing the display mode of the seek bar 10 according to the granularity of the seek bar 10. Therefore, it is possible to obtain the image display device 1 with high convenience.

  FIG. 8 illustrates the configuration of the seek bar 10 that has different sounds when moving the icon 10a according to the granularity.

  FIG. 8A shows a state of the seek bar 10 in a normal display state in which the reproduction time per section 10z is 10 minutes. As shown in FIG. 8A, in the initial state, the seek bar control unit 32 outputs a “click” sound from the speaker 4 when the icon 10 a is moved.

  FIG. 8B shows the state of the seek bar 10 in the display state in which the reproduction time per section 10z is 10 seconds and the granularity is reduced in four stages from the normal display state. As shown in FIG. 8B, the seek bar control unit 32 causes the speaker 4 to output a “beep” sound when the icon 10 a arranged on the seek bar 10 having a four-step granularity is moved.

  Similarly, at other stages, the seek bar control unit 32 causes the speaker 4 to output a different sound for each stage when the icon 10a is moved.

  In this way, the seek bar control unit 32 outputs the moving sound that is output when the icon 10a moves the position on the seek bar 10 from the speaker 4 with different granularity, so that the user can audibly hear the current sound. The set granularity can be recognized. For this reason, the image display apparatus 1 with high convenience can be obtained.

(Configuration to slide the allocation time to seek bar 10)
FIG. 9 is a diagram for explaining the operation of changing the time allocated to the seek bar 10 by sliding the content within the total playback time.

  As a result of reducing the granularity per division of the seek bar, the scale of the content does not fit in the seek bar 10. In this case, a left feed icon or a right feed icon may be arranged and displayed near the left end 10b and the right end 10c of the seek bar 10.

  As shown in (a) of FIG. 9, first, assuming that the image display device 1 is reproducing content whose total reproduction time is 60 minutes, the image display device 1 is shown in (a) of FIG. As described above, the time “0:00” as the leading end value 11b of the content is displayed in the vicinity of the left end 10b of the seek bar 10, and the time “60:00” as the end value 11c of the content is displayed at the right end 10c of the seek bar 10. indicate.

  Next, in order to reduce the granularity of the seek bar 10, the user long presses the icon 10 a at the time “30:00” position with a finger. As an example, it is assumed that the user long presses the icon 10a for 5 seconds.

  Then, as shown in FIG. 9B, the input information determination unit 33 determines that the user has pressed the icon 10a for 5 seconds, and the seek bar control unit 32 determines that the icon 10a is included in the total content playback time. The time of the left end 10b and the time of the right end 10c of the seek bar 10 are assigned so that the position of the icon 10a on the seek bar 10 is the same before and after the time axis expansion, including the position shown as the origin. . Here, the seek bar control unit 32 assigns the time position “29:30” to the left end 10 b of the seek bar 10 and assigns the time position “30:30” to the right end 10 c of the seek bar 10. The seek bar control unit 32 displays “29:30” in the vicinity of the left end 10b of the seek bar 10 and displays “30:30” in the right end 10c.

  Further, the seek bar control unit 32 displays the left feed icon 10d on the display unit 2 in the vicinity of the left end 10b, further to the left of the left end 10b of the seek bar 10, and further to the right of the right end 10c of the seek bar 10. The right-feed icon 10e is displayed on the display unit 2 in the vicinity of the right end 10c.

  Thus, since the seek bar control unit 32 assigns the time axis so that the position of the icon 10a on the seek bar 10 is the same before and after the time axis is expanded, the icon position changes before and after the time axis is expanded. It is not necessary to move the finger to the user and the usability is high.

  Next, as shown in FIG. 9 (c), when the content control unit 31 acquires information that the finger touches the right-feed icon 10e through the input unit 3, the seek bar control unit 32 displays the icon 10a. While moving to the right end 10c of the seek bar 10 and displaying it on the display unit 2, the content control unit 31 displays a moving image by skipping to the time position “30:30” indicated by the position of the icon 10a.

  Then, as shown in (d) of FIG. 9, when the content control unit 31 obtains information that the finger has touched the right-feed icon 10 e through the input unit 3 again, the seek bar control unit 32 Of the content playback time currently allocated to the seek bar 10, the next one minute time is allocated. Then, the seek bar control unit 32 displays “30:30” in the vicinity of the left end 10b of the seek bar 10, displays “31:30” in the vicinity of the right end 10c of the seek bar 10, and the content control unit 31 The moving image is displayed skipping to the time position “31:30” indicated by the position of the icon 10a.

  Then, as shown in FIG. 9 (e), when the user keeps the finger in contact with the right-feed icon 10e and the time allocated to the seek bar 10 slides until the end of the content playback time, the seek bar control unit 32 Deletes the display of the right advance icon 10e and displays “60:00”, which is the end value 11c of the content, in the vicinity of the right end 10c.

  In this way, when the time axis is slid to the end value 11c of the total content playback time, the seek bar control unit 32 turns off the display of the right-feed icon 10e, thereby allowing the user to end the end of the total content playback time. It can be visually recognized that the allocation time for the seek bar 10 has been slid to the value 11c.

  Similarly, when the user touches the left feed icon 10d with the finger, the content control unit 31 detects the contact, and the content control unit 31 detects the content playback time before the time currently assigned to the seek bar 10. Are sequentially assigned, and the playback time positions indicated by the respective ends are displayed in the vicinity of the left end 10b and the right end 10c.

  When the time axis is slid to the leading value 11b of the total content playback time, the seek bar control unit 32 turns off the display of the left feed icon 10d, so that the user can delete the leading value 11b of the total content playback time. Up to this point, it can be visually recognized that the time allocated to the seek bar 10 has been slid.

  Next, a method for finely setting a playback position away from the current playback position will be described with reference to FIG.

  FIG. 10 is a diagram for explaining an operation for finely setting a playback position far from the current playback position.

  As shown in FIG. 10A, it is assumed that the seek bar 10 has been assigned a total playback time of 60 minutes and the icon 10a is at the position “5:00”.

  At this time, if the user wants to move the icon 10a to the position “45:30”, the icon 10a at the position “5:00” is moved to “45:45” as shown in FIG. The seek bar 10 is slid to a position near 30 ”, for example, a position“ 45:40 ”.

  Then, as shown in FIG. 10C, the icon 10a slid to the position “45:40” is pressed for 3 seconds on the spot. Then, the seek bar control unit 32 sets the seek bar 10 so that the position of the icon 10a is the same with the position of “45:40” of the icon 10a as the origin, and the allocated time length is 1 minute. The time “45:00” is assigned to the left end 10b of the seek bar 10, and the time “46:00” is assigned to the right end 10c.

  Then, the seek bar control unit 32 displays “45:00” in the vicinity of the left end 10b of the seek bar 10 and displays “46:00” in the vicinity of the right end 10c.

  Then, the user slides the icon 10a to the position “45:30”. In this way, the user can make fine position settings.

In this way, the user can simply press and hold the icon 10a to display the time axis of the seek bar 10 in an enlarged manner, so that the granularity of the seek bar 10 can be changed with a simple operation, and the distance of the icon 10a can be changed. You can make long movements and fine position settings.

  In this way, the seek bar control unit 32 moves the playback time zone adjacent to the playback time zone currently assigned to the seek bar 10 out of the content time axis to the left for assigning to the seek bar 10 with a constant magnification value. Icon 10d and right-feed icon 10e are displayed on the display unit 2. This makes it possible to achieve both quick movement to a playback position away from the current playback position and fine position setting.

  In addition, when the time axis is enlarged / reduced, the seek bar control unit 32 performs the time of the icon 10a when executing the enlargement / reduction process so that the position of the icon 10a does not move before and after the time axis assigned to the seek bar 10 is enlarged. From the position and the granularity of the time axis after the enlargement / reduction processing, the position of the content playback time to be assigned to each of the left end 10b and the right end 10c of the seek bar 10 is assigned. For this reason, the position of the icon 10a does not move before and after enlargement / reduction, and it is possible to prevent usability deterioration.

  FIG. 11 is a diagram illustrating a state in which the magnification fixing icons arranged in the vicinity of the seek bar are arranged.

  Further, as shown in FIG. 11, the seek bar control unit 32 sets the magnification value near the seek bar 10, for example, further to the right of the right-feed icon 10 e, and the time axis magnification of the content currently allocated to the seek bar 10. A magnification fixing icon 10f for fixing the value may be displayed on the display unit 2.

  When the seek bar control unit 32 detects information indicating that the user's finger is in contact with the magnification fixing icon 10f through the input unit 3, next, information indicating that the user's finger is in contact with the magnification fixing icon 10f is acquired. Until now, the seek bar control unit 32 fixes the time axis with the granularity currently assigned to the seek bar 10 and fixes the seek bar 10 without changing the granularity even when the icon 10a is pressed for a long time.

  Thereby, it is possible to prevent the time axis assigned to the seek bar 10 from being changed to a magnification value not intended by the user due to an erroneous operation or the like. For this reason, operativity can be improved.

(Description of processing of image display device 1)
Next, a processing flow of the image display device 1 will be described with reference to FIGS. 1 and 12. FIG. 12 is a flowchart showing the process flow of the image display apparatus 1.

  When the content control unit 31 acquires content playback instruction information input from the user through the input unit 3, the content control unit 31 reads a content playback program from the ROM 21, executes the program, and information necessary for setting the seek bar 10. The seek bar display information 22b is stored in the RAM 22. In this way, the content control unit 31 reproduces the content instructed to be reproduced by the user (step S101).

  Further, the seek bar control unit 32 assigns the total reproduction time of the content to be reproduced to the length of the seek bar 10 by setting the magnification value to 1 which is an initial value. Then, the content control unit 31 causes the display unit 2 to display an image of the content being played back, and the seek bar control unit 32 displays the seek bar 10, the icon 10 a, the content tip value 11 b, and the display unit 2. The end value 11c and the like are displayed (step S102).

  As an example, the seek bar control unit 32 allocates the total playback time of 60 minutes to the seek bar 10 and causes the display unit 2 to display the seek bar 10 and the icon 10a. Further, the seek bar control unit 32 displays “00:00” as the tip value 111b near the left end 10b of the seek bar 10 and “60:00” as the end value 11c near the right end 10c of the seek bar 10 on the display unit 2. Let

  Next, when the user touches the icon 10a with a finger, the seek bar control unit 32 acquires information that the user is touching the icon 10a through the input unit 3 (step S103).

  Then, the input information determination unit 33 determines whether or not the user has long pressed the icon 10a. That is, when the input information determination unit 33 does not move while the position (coordinates) of the user's finger in contact with the input unit 3 is fixed, the input information determination unit 33 is registered in the magnification value information 22d. A predetermined time having the smallest value is acquired (step S104).

  Then, the input information determination unit 33 determines whether or not the elapsed time after the user has touched the icon 10a with the acquired predetermined time has passed (step 105).

  When the input information determination unit 33 determines that the elapsed time since the user has touched the icon 10a with the acquired predetermined time has not elapsed (NO in step S105), the input information determination unit 33 returns to step S103.

  In addition, when the input information determination unit 33 determines that the user is holding down for a long time, that is, the elapsed time since the user touched the icon 10a with the predetermined time acquired by the input information determination unit 33 has elapsed. If it is determined that it has been determined (YES in step S105), the magnification value changing unit 34 acquires the magnification value registered in the magnification value information 22d in association with the predetermined time determined that the input information determining unit 33 has passed ( Step S106).

  Then, the seek bar control unit 32 refers to the content reproduction position information 22c, and sets the magnification value changing unit so that the position of the icon 10a on the seek bar 10 is the same with the current reproduction position (the position of the icon 10a) as the origin. The time axis of the content being reproduced is enlarged by the magnification value acquired by 34 and assigned to the seek bar 10. The seek bar control unit 32 causes the display unit 2 to display the seek bar 10, the tip value 11b, and the end value 11c after the time axis expansion (step S107).

  Next, the input information determination unit 33 determines whether or not the user's finger has been removed from the icon 10a (step S108).

  When the input information determination unit 33 determines that the user's finger is not separated from the icon 10a (NO in step S108), the input information determination unit 33 determines that the predetermined time is larger than the predetermined time acquired from the magnification value information 22d. It is determined whether it is registered. That is, the input information determination unit 33 determines whether or not the predetermined time acquired from the magnification value information 22d is the upper limit of the predetermined time registered in the magnification value information 22d (step S109).

  When the predetermined time larger than the predetermined time acquired by the input information determination unit 33 from the magnification value information 22d is registered (NO in step S109), the input information determination unit 33 previously determines from the magnification value information 22d. A predetermined time having the next largest value after the acquired predetermined time is acquired from the magnification value information 22d (step S110).

  And the input information determination part 33 determines whether the elapsed time after a user made a finger contact the icon 10a passed the said acquired predetermined time. That is, the process returns to step S105.

  In step S109, when the predetermined time larger than the predetermined time acquired by the input information determination unit 33 from the magnification value information 22d is not registered, that is, the predetermined time acquired by the input information determination unit 33 from the magnification value information 22d. When the upper limit is reached (YES in step S109), the input information determination unit 33 determines whether or not the user's finger is released from the icon 10a. That is, the process returns to step S108.

  In step S108, when the input information determination unit 33 determines that the user's finger has been released from the icon 10a (NO in step S108), the input information determination unit 33 determines the elapsed time since the user's finger has been released from the icon 10a. Then, it is determined whether or not a predetermined time (for example, 1 second) determined in advance has elapsed (step S111).

  Then, before the predetermined time (for example, 1 second) elapses, when the user touches the icon 10a again (NO in step S111), the user touches the icon 10a through the input unit 3. The seek bar control unit 32 acquires information to that effect. That is, the process returns to step S103.

  On the other hand, when the input information determination unit 33 determines that the elapsed time after the user's finger is released from the icon 10a has passed a predetermined time (for example, 1 second) (YES in step S111), the magnification value is changed. The unit 34 determines whether or not a magnification value smaller than the magnification value acquired from the magnification value information 22d is registered. That is, the magnification value changing unit 34 determines whether or not the magnification value acquired from the magnification value information 22d is the lower limit of the magnification value registered in the magnification value information 22d (step S112).

  When a magnification value smaller than the magnification value acquired by the magnification value changing unit 34 is registered in the magnification value information 22d (NO in step S112), the magnification value changing unit 34 determines that the magnification value acquired previously is Next, the magnification value with the next smallest value is acquired from the magnification value information 22d (step S113).

  Then, the seek bar control unit 32 refers to the content reproduction position information 22c, and sets the magnification value changing unit so that the position of the icon 10a on the seek bar 10 is the same with the current reproduction position (the position of the icon 10a) as the origin. The time axis of the content being reproduced is reduced by the magnification value acquired by 34 and assigned to the seek bar 10. Then, the seek bar control unit 32 causes the display unit 2 to display the seek bar 10, the tip value 11b, and the terminal value 11c after the time axis reduction (step S104). Then, the process returns to step S111.

  In step S112, when a magnification value smaller than the magnification value acquired by the magnification value changing unit 34 is not registered in the magnification value information 22d, that is, the magnification value changing unit 34 previously acquired from the magnification value information 22d. If it is determined that the magnification value is the lower limit of the magnification value registered in the magnification value information 22d (YES in step S112), the process returns to step S103.

  In step S108, when the user lifts his / her finger from the icon 10a (YES in step S108), the time axis of the content assigned to the seek bar 10 is reduced stepwise in steps S111 to S114. As described above, after YES in step S108, the process returns to step S102, and the magnification value changing unit 34 returns the magnification value to the initial value of 1 and assigns the total playback time of the content to the length of the seek bar 10, You may display on the display part 2.
