Description

  The present invention relates to a display device and a display method.

  In recent years, for example, display devices such as liquid crystal displays, plasma displays, and field emission displays have been increasingly accepted, and these display devices can display and provide various contents to various users. For example, when the user desires to view other content while viewing one content, the display device switches the displayed video from the one content to the other content.

Japanese Patent Application Laid-Open No. 2003-224772

  However, in many cases, switching of contents in the display device is suddenly performed. That is, when another content is selected from the state in which one content is displayed, the one content is erased and the display screen becomes blank (for example, a black image), and then the other content is displayed on the display screen. Is displayed. In the blank period, preparation processing for displaying other contents is usually performed, and the other contents are often displayed when the preparation is completed.

  Such a blank display screen may give a user discomfort. That is, the user feels like waiting on the display device without displaying the content he / she wants to view. Many users feel uncomfortable with such a state.

  Even if such a blank state does not occur, if the display screen is suddenly switched from one content to another, the user's discomfort often cannot be wiped off.

  Furthermore, as a method for switching different contents, Japanese Patent Application Laid-Open No. 2004-151867 has a technique for displaying the video of the content after switching on a part of the video of the content before switching. However, such content switching is indistinguishable from the case where such small content is included in the content, and the user may feel uncomfortable. In addition, the content switching in this case is often not smooth and lacks a sense of reality.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a user with a sense of realism that facilitates switching of content and provides the user with the switching of content to be displayed. It is an object of the present invention to provide a new and improved display device and display method that can be further improved.

  In order to solve the above problems, according to an aspect of the present invention, a playback unit that plays back content including at least one of video and audio, a selection unit that selects content to be played back by the playback unit, and the selection unit A display control unit that moves the display position of at least one video of the one content and the other content being reproduced by the reproduction unit when the content selected by the player is switched from one content to another content And a sound control unit that moves a localization position where a sound image of at least one of the one content and the other content is localized in accordance with the movement of the display position by the display control unit. Provided.

  According to this configuration, the content reproduced by the reproduction unit is switched from one content to another content by the selection unit. Then, at least one display position of both contents is moved by the display control unit, and a localization position of the sound image by at least one sound of both contents is moved by the audio control unit. That is, according to this configuration, when content is switched, the content can be switched while moving at least one display position of the content before and after switching and at least one sound image localization position of the content.

  The direction in which the voice control unit moves the localization position may be the same as the direction in which the display control unit moves the display position.

  The display control unit may be capable of moving the display position in two or more directions.

  And a moving direction determination unit that determines a direction in which at least one of the display position and the localization position is moved based on at least one of the attribute information of the one content and the attribute information of the other content. Also good.

  The moving direction determination unit determines a speed of moving at least one of the display position and the localization position based on at least one of the attribute information of the one content and the attribute information of the other content. Also good.

  In addition, the display control unit moves the display position forward or backward of a user who views the displayed content from the front by changing a display magnification of at least one of the one content and the other content. May be.

  The display control unit may move the display position to the left or right of the user who views the displayed content from the front.

  The audio control unit may change the sound pressure of at least one of the one content and the other content.

  In order to solve the above problem, according to another aspect of the present invention, it is determined whether or not the content to be played back including at least one of video and audio is switched from one content to another. When it is determined in the content switching confirmation step and the content switching confirmation step that the content to be reproduced is switched from the one content to the other content, at least one of the one content and the other content And a moving step of moving a localization position where a sound image of at least one of the one content and the other content is localized in accordance with the movement of the display position. Is provided.

  As described above, according to the present invention, when the content to be displayed is switched, the switching of the content can be performed more smoothly, and the sense of presence given to the user can be further improved.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  The display device according to each embodiment of the present invention described below is based on the display position or sound of at least one video or still image of both contents when the content to be displayed is switched from one content to another. The localization position where the sound image is localized is moved.

  Here, the content before and after switching is referred to as “viewing content (an example of one content) (A)” and “switching content (an example of other content) (B)”, respectively. However, “viewing” does not mean the content that is actually viewed at a specific time point, but simply means that the content was viewed before switching. That is, after the switching, the switching content is viewed, but here, for convenience of explanation, the content viewed after the switching is referred to as switching content. The content displayed by the display device is not particularly limited in type or content, but the content includes at least one of video (including still images / moving images) and audio. It is desirable that at least one of the viewing content and the switching content includes video, and that one (which may be content that does not include video) also includes audio. However, for convenience of explanation, a case where video and audio are included in both the viewing content and the switching content will be described.

Hereinafter, the display device according to the first embodiment of the present invention will be described in detail. In order to facilitate understanding of the display device, the following description will be given in the following order.

<First Embodiment>
[1. Display system configuration]
First, the configuration of a display system including a display device according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 is an explanatory diagram for explaining a display system according to the first embodiment of the present invention.

  As shown in FIG. 1, the display system 1 includes a display device 10 and speakers SPL and SPR.

  The display device 10 reproduces content, displays video of the content, and outputs audio. Examples of such a display device include, for example, a cathode ray tube (CRT), a liquid crystal display (LCD), a plasma display (PDP), a field emission display (FED), and a field emission display (FED). Organic electroluminescence display (organic EL, OELD: Organic Electroluminescence Display), video projector, and the like. Still other display devices include various types of display devices that can display content such as general-purpose computers, notebook computers, PDAs (Personal Digital Assistants), and mobile phones. That is, the display device 10 may be any display device as long as it is a device capable of reproducing content, displaying video of the content, and outputting sound. Hereinafter, the display device according to each embodiment of the present invention is simply referred to as a “display device”.

  The display device 10 has a display screen M, and displays video included in the reproduced content on the display screen M. In addition, the display device 10 outputs the audio of the reproduced content from an audio output unit that constitutes a surround sound. Examples of the audio output unit include a speaker built in the display device 10, an external speaker, a headphone, a headset, an earphone, and the like. The surround system may be monaural (1 channel), stereo (2 channels), 3 channels or more, for example, 5.1 channels or 7.1 channels. Here, the case where the display device 10 has a multi-channel surround system including a built-in speaker (not shown) and external speakers SPL and SPR will be described.

  The speakers SPL and SPR are examples of an external audio output unit and are rear speakers. It is assumed that the user (that is, the viewer) U is viewing the display outer surface in front of the display screen M of the display device 10. In this case, the speaker SPL is a rear speaker located on the left rear side of the user U, and the speaker SPR is a rear speaker located on the right rear side of the user U.

  The speakers SPL and SPR are driven by an audio signal from an audio control unit 17 (see FIG. 2) included in the display device 10 described later and output audio as sound, in the same manner as the speaker built in the display device 10. . In the following, for convenience of explanation, the external speakers SPL and SPR and the internal speaker (not shown) are collectively referred to as “audio output unit 18 (see FIG. 2)”, and include the external speakers SPL and SPR. The audio output unit 18 will be described as one of the configurations of the display device 10.

  In the following, when the user U is viewing the display outer surface in front of the display screen M of the display device 10, the left direction of the user U (x-axis positive direction) is simply referred to as “left” or the like. The right direction of U (the negative x-axis direction) is also simply referred to as “right” or the like. The forward direction (the negative y-axis direction) of the user U is also simply referred to as “front”, and the backward direction (the positive y-axis direction) of the user U is also simply referred to as “rear”. It should be noted that the front of the display device 10 (that is, the direction in which the display screen M is formed; the y-axis positive direction) is simply referred to as “front” or the like, and the back surface of the display device 10 (the negative y-axis direction). ) Is also simply referred to as “rear surface” or “rear surface”. That is, the front direction of the user U corresponds to the rear surface direction of the display device 10, and the rear direction of the user U corresponds to the front direction of the display device 10. Further, the upward direction of the user U and the display device 10 is also simply referred to as “up”, and the downward direction of the user U and the display device 10 is also simply referred to as “down”.

[2. Configuration of display device]
Next, the configuration of the display device according to the present embodiment will be described with reference to FIG. FIG. 2 is an explanatory diagram illustrating the configuration of the display device according to the present embodiment.

  As illustrated in FIG. 2, the display device 10 includes a content acquisition unit 11, a content selection unit 12, a movement direction determination unit 13, a reproduction unit 14, a display control unit 15, a display unit 16, and a sound control unit. 17 and an audio output unit 18.

  The content acquisition unit 11 acquires content to be played back by the display device 10. The content acquisition unit 11 can acquire a plurality of contents at the same time. That is, the content acquisition unit 11 can simultaneously acquire viewing content, switching content, and other content. The acquisition source from which the content acquisition unit 11 acquires content is not particularly limited. Examples of the acquisition source include broadcast waves such as terrestrial and satellite waves, a storage device (not shown) mounted inside the display device 10, and a recording device arranged outside and connected to the display device 10. (Not shown), a content distribution server (not shown) that publishes content on a network such as the Internet, and the like. However, the acquisition source from which the content acquisition unit 11 acquires content is not limited to these examples.

  Note that the content acquired by the content acquisition unit 11 includes video information representing video and audio information representing audio as described above. This content further includes attribute information. “Attribute information” is information indicating the attribute of the content. The content attributes include, for example, the content type (genre), outline of the content, information on the performers and producers, broadcast time zone and date, broadcast channel, date and date when the content was created, and the content. This includes information / broadcast formats, acquisition methods, etc. provided to viewers in relation to the target audience segment / content. Examples of such attribute information include EPS (Electronic Program Guide).

  There is a possibility that the content acquired by the content acquisition unit 11 is in a format in which the information included in the content cannot be read normally, for example, the plurality of pieces of information are collected, compressed, or encrypted. There is also. In that case, the content acquisition unit 11 may convert the acquired content into a readable format, for example, by returning it to a plurality of pieces of information, decompressing it, or combining it. Furthermore, the content acquisition unit 11 may play a role of a tuner or the like when acquiring broadcast content. However, it goes without saying that such conversion and tuning functions may be included in the acquisition source from which the content acquisition unit 11 acquires content.

  The content selection unit 12 is an example of a selection unit, and selects content to be played back by the playback unit 14 from a plurality of contents acquired by the content acquisition unit 11. Note that switching the content selected by the content selection unit 12 from the viewing content to the switching content is called “content switching” or the like.

  Such content switching is performed by the content selection unit 12 such as an operation by a user U to an operation unit (not shown) such as a remote controller or a button, a preset timer, or the end of viewing content. It is performed at various timings (time points). At this time, for example, the time when the user U performs an operation of switching the content, the time when a preset time interval elapses or reaches the time, and the time when the viewing content ends (preferably immediately before) This is also referred to as “switching start timing (t0)”. That is, the switching start timing means a point in time when the display device 10 starts switching from the viewing content to the switching content, and various modes can be considered as to how the timing is set. For example, at the switching start timing, the display device 10 starts moving the content display position and the sound image localization position, and when the movement is completed, switching from the viewing content to the switching content is completed. The timing at which this switching is completed is also referred to herein as “switching completion timing (t1 or t2)”. A period from the switching start timing to the switching end timing is also referred to as a “switching period”. However, these timings and periods are set for convenience of explanation and do not limit the present embodiment. For example, it goes without saying that the timing error, the difference in definition, the width of the period, and the like may exist.

  That is, when content switching is performed, the content selection unit 12 selects the viewing content before the switching start timing, and selects the switching content after the switching start timing. Then, the content selection unit 12 outputs the selected content to the reproduction unit 14. However, the content selection unit 12 outputs the viewing content together with the switching content to the reproduction unit 14 at least from the switching start timing to the switching completion timing or for a while after that.

  When the content is switched, the movement direction determination unit 13 moves at least one of the display position of the video displayed on the display screen M and the localization position of the audio image output from the audio output unit 18. To decide. That is, as described above, the display device 10 according to the present embodiment moves the display position of the content video and the localization position of the sound image of the audio, and the movement direction determination unit 13 determines the movement direction. .

  The movement direction determination unit 13 can determine the movement direction from a plurality of directions such as a left direction, a right direction, a front direction, a rear direction, a rotation, and a combination of these. Specific examples of these moving directions are described in [3. [Operation of Display Device]

  The movement direction determined by the movement direction determination unit 13 may be set in advance, but here, the movement direction determination unit 13 may be one movement direction (two movement directions) from among a plurality of movement directions. ) Will be described. At this time, the moving direction determination unit 13 may determine the moving direction based on at least one of the attribute information of the viewing content and the attribute information of the switching content, for example. Further, the moving direction determination unit 13 can determine not only the moving direction but also the moving speed of the video and / or sound image in the moving direction. Also in this case, the moving speed may be set in advance, or may be determined based on at least one of the attribute information of both contents. The determination of the moving direction and moving speed based on this attribute information will be described in [3-5. [Example of determining content switching method] will be described in detail.

  The playback unit 14 plays back the content acquired from the content selection unit 12. In addition, this reproduction | regeneration part 14 can reproduce | regenerate the some content, when a some content is acquired from the content selection part 12. FIG. Further, the reproduction unit 14 can reproduce not only the content acquired from the content selection unit 12 but also a plurality of content acquired by the content acquisition unit 11. By reproducing and displaying a plurality of contents on the display screen M, the display device 10 can cause the user U to perform a content selection operation while referring to the contents.

  The display control unit 15 controls the display state (including the display position) of the video displayed on the display screen M, that is, the video of the content played back by the playback unit 14. On the other hand, the display unit 16 has a display screen M, and displays the video transmitted from the display control unit 15 on the display screen M based on the control by the display control unit 15. When the content is not switched, the display control unit 15 displays the content reproduced by the reproduction unit 14 on the display screen M. At this time, when the user U is viewing the content, the display control unit 15 can display the video of the content on the entire display screen M.

  On the other hand, at the time of content switching, the display control unit 15 moves the display position of at least one of viewing content (content before switching) and switching content (content after switching). At this time, the display control unit 15 moves the display position in the movement direction determined by the movement direction determination unit 13. On the other hand, as described above, the movement direction determination unit 13 can determine one movement direction or two movement directions from two or more directions. Therefore, the display control unit 15 can move the display position in two or more directions, and can move the viewing content and the switching content in different directions. Of course, the display control unit 15 can also move the display position of only one of the viewing content and the switching content. In the following, when both contents are moved, a case where the moving direction of the viewing content is the same as the moving direction of the switching content will be described.

  An example of movement of the display position by the display control unit 15 is also described in [3. [Operation of Display Device] will be described in detail.

  The audio control unit 17 causes the sound of the content reproduced by the reproduction unit 14 to be output to an audio output unit 18 such as an external speaker SPL, SPR or a built-in speaker (not shown). At this time, the sound control unit 17 can adjust the output sound pressure (that is, the volume, for example) of the sound output from the sound output unit 18, and can move the localization position of the sound image by the sound. In addition, the sound image in this embodiment means what the user U who listens to the audio | voice of a content recognizes as if the sound is making the image. The localization position of the sound image is, for example, a position where the user U recognizes that the sound image, that is, the sound source is located. Although the sound image and the localization position of the sound image have been described here, this description does not limit the present embodiment, and the sound image and the localization position can be understood in a broad sense.

  The sound control unit 17 has a sound pressure adjusting circuit (not shown) such as an amplifier or an amplifier in order to adjust the sound pressure. The sound control unit 17 includes, for example, a sound image localization processing circuit in order to move the localization position of the sound image. However, the sound pressure adjustment circuit that adjusts the sound pressure may be used for the localization processing of the sound image. The sound pressure adjustment circuit and the sound pressure adjustment circuit are desirably provided in the number of channels of the surround system, for example.

  Examples of the sound image localization processing circuit include, for example, an FIR filter (Finite Impulse Response Filter). When the sound image localization processing circuit is an FIR filter, as many FIR filters as the number of channels of the surround system are provided. Then, each FIR filter performs a convolution operation process on the audio information of the content reproduced by the reproduction unit 14, thereby adding a phase difference to the sound output from each channel. As a result, the sound image localization processing circuit can localize the sound image of the sound being reproduced at the determined position of the sound image. At this time, the sound pressure adjustment for each channel is performed by the sound pressure adjustment circuit, and a sound pressure difference is loaded between the channels, so that the sound image can be localized more effectively at a predetermined position. The movement of the sound image localization position by the sound image localization processing circuit is determined by a head-related transfer function (Head Related Transfer Function) corresponding to the localization position where the sound image should be localized, using coefficients of a plurality of coefficient units (not shown) included in the FIR filter. This can be done by sequentially changing to the required coefficient values. At the same time, the sound pressure difference is adjusted by the sound pressure adjusting circuit. Note that the FIR filter mentioned here is merely an example of a sound image localization processing circuit, and it goes without saying that the sound control unit 17 may include another sound image localization circuit.

  The audio control unit 17 moves the localization position of at least one of the viewing content (content before switching) and the switching content (content after switching) during content switching. At this time, the voice control unit 17 moves the display position in the movement direction determined by the movement direction determination unit 13, similarly to the display control unit 15. The moving direction determination unit 13 determines the direction in which the sound image localization position is moved according to the direction in which the display position is moved. That is, the sound control unit 17 moves the localization position of the sound image in accordance with the movement of the display position by the display control unit 15. The moving direction of the display position and the moving direction of the sound image may be different directions, but are preferably the same direction.

  Furthermore, the sound control unit 17 normally adjusts the sound pressure in accordance with the operation of the user U or the like, but may change the sound pressure of at least one of the viewing content and the switching content at the time of content switching.

  An example of the movement of the sound image localization position by the voice control unit 17 is also described in [3. [Operation of Display Device] will be described in detail.

  As described above, the audio output unit 18 is an external and / or built-in audio output unit, such as the speakers SPL and SPR and / or the built-in speaker (not shown) in FIG.

[3. Operation of display device]
Further, the operation of the display device according to the present embodiment will be described with reference to FIG. FIG. 3 is an explanatory diagram for explaining the operation of the display device according to the present embodiment.

  As shown in FIG. 3, first, when the user U is viewing the viewing content, step S01 (an example of a content switching confirmation step) is processed. In step S01, the content selection unit 12 confirms whether new content (that is, switching content) has been selected. That is, in this step S01, it is determined whether or not content switching has been performed. If the content is not switched, this step S01 is repeated. On the other hand, if the content has been switched, the process proceeds to step S03.

  In step S03, the moving direction determination unit 13 confirms at least one of the viewing content attribute information and the switching content attribute information. Then, the process proceeds to step S04.

  In step S05, the moving direction determination unit 13 determines the moving direction of the display position and the sound image localization position based on the attribute information confirmed in step S03. However, when the moving direction is determined in advance, the previous steps S03 and S05 are not necessarily required. After the process of step S05, the process proceeds to step S07.

  In step S07 (an example of a movement step), a process for moving the display position and the sound image localization position is performed. That is, the display control unit 15 moves the display position of at least one of the viewing content and the switching content in the direction determined in step S05. In addition, the sound control unit 17 moves the localization position of the sound image based on the sound of at least one of the viewing content and the switching content in the direction determined in step S05. An example of the movement in step S07 will be described later. After step S07, step S09 is processed.

  In step S09, the playback unit 14 confirms whether or not the playback of the switching content has ended. Examples of the end of reproduction include, for example, when the switching content is completed or when the power of the display device 10 is turned off. When the reproduction is finished, the operation is finished, but when the reproduction is not finished, the processes after step S01 are repeated. However, it goes without saying that when the processing after step S01 is performed again, the switching content becomes a new viewing content. In addition, this step S09 is not always necessary, and it is needless to say that steps S01 to S09 may be always processed during the operation of the display device 10.

[3-1. First example of content switching by display device]
The operation of the display device 10 according to the present embodiment has been described above. Here, an example of the content switching operation by the display device, that is, an example of a method of moving the display position and the sound image localization position in step S05 will be described. However, the content switching example described here is merely an example, and it goes without saying that various types of switching are possible. For example, in the movement example described below, a case where both the viewing content and the switching content are moved will be described, but it is of course possible to move either one.

  First, a first example of content switching by the display device 10 according to the present embodiment will be described with reference to FIGS. FIG. 4 is an explanatory diagram illustrating display positions in the first example of content switching by the display device according to the present embodiment. FIG. 5 is an explanatory diagram for explaining the sound image localization position in the first example of content switching by the display device according to the present embodiment. FIG. 6 is an explanatory diagram for explaining the sound pressure in the first example of content switching by the display device according to the present embodiment. 7 and 8 are explanatory diagrams for explaining a concept of a first example of content switching by the display device according to the present embodiment.

(Display position)
First, the movement of the display position by the display control unit 15 will be described with reference to FIG.
In this first example, the display control unit 15 moves the video display position backward. For example, when a certain video is displayed on the display screen M and the magnification of the video is increased and the image is enlarged, the user U recognizes that the display video has moved backward. On the other hand, when the image magnification is reduced and reduced, the user U recognizes that the display image has moved forward. Using this effect, the display control unit 15 moves the display position backward (it is of course possible to move it forward). This will be described more specifically.

  As shown in FIG. 4, it is assumed that the video of the viewing content A is displayed on the display screen M of the display device 10 at a magnification of 1 until the switching start timing t0. Then, it is assumed that the content switching starts at the switching start timing t0. Then, the display magnification of the video of the viewing content A is increased along the line L1, and the display position moves rearward (y-axis positive direction in FIG. 1) and gradually approaches the user U. Then, the display position of the viewing content A apparently reaches the position of the user U (timing t1). Thereafter, the viewing content A may move further backward, but it is desirable that it is not displayed after the timing t1. On the other hand, the video of the switching content B, which is the content after switching, may be displayed on the display screen M of the display device at a magnification of 1 as indicated by the lines L2 and L3 when the video of the viewing content A disappears. . The video of the switching content B may be displayed along the lines L4 and L3 by, for example, displaying at a magnification of 1 or less at the timing t1 and then increasing the magnification to 1. Then, at the switching completion timing t2, the switching content B after switching is displayed on the display screen M at a magnification of 1.

(Sound image localization position)
FIG. 5 shows an example of moving the localization position of the sound image.
As shown in FIG. 5, the localization position of the sound image is desirably moved in the same direction and at the same speed as the movement of the display position shown in FIG. However, in the movement of the display position shown in FIG. 4, the ideographic position of the video of the viewing content A before switching is not displayed after the timing t1, but the localization position of the sound image by the viewing content A is also after the timing t1. It is desirable to move in the same direction.

(Sound pressure)
FIG. 6 shows a change in sound pressure of voice.
In FIG. 6, instead of showing the sound pressure for each channel of the surround system, the average sound pressure of all the channels is representatively shown. In the first example, the video display position and the sound image localization position move backward. Therefore, it is not necessary to change the sound pressure between the left and right channels.

  It is desirable that the sound pressure of the viewing content A be gradually decreased after the switching start timing t0 as indicated by the line L5 (fade out). However, in the first example, as described above, both the display position of the video of the viewing content A and the localization position of the sound image first move backward so as to approach the user U. Therefore, as a modification, for example, as indicated by a line L6, the sound pressure of the viewing content A is not decreased until the timing t1 when the display position reaches the user U position, and the sound pressure is decreased after the timing t1. It is also possible to make it. As yet another modification, for example, as shown in a line L7, the sound pressure of the viewing content A can be temporarily increased until the timing t1, and the sound pressure can be decreased after the timing t1. In this case, since the sound pressure increases as the display position and the sound image localization position approach, a sense of reality can be added by moving the display position and the sound image localization position.

  On the other hand, the sound pressure of the switching content B may be a constant sound pressure after timing t1 as shown by lines L8 and L9, for example, but gradually increases as shown by lines L10 and L9. Good (fade in). In this case, the sound of the viewing content A and the sound of the switching content B are cross-faded, and the sense of reality can be further increased.

(concept)
By adjusting the display position / sound image localization position / sound pressure as in the first example, the user U recognizes that the display device 10 performs the following content switching.

  That is, as shown in FIG. 7, the user U recognizes as if a plurality of contents are superimposed. In FIG. 7, the viewing content A is displayed on the display screen M. However, when the content is switched, as shown in FIG. 8, the display position of the viewing content A, the sound image localization position, and the sound pressure move closer to the user U and move further in the moving direction V1. As has been done, user U recognizes. After the viewing content A is moved, the switching content B is displayed on the display screen M. Accordingly, the user U has an impression that a plurality of contents are superimposed and the superimposed contents are turned in the front-rear direction by switching the contents.

  Note that the switching period (for example, from t0 to t2) in which these content switching processes are performed is too short to make the user U recognize as if the content has moved, and if too long, the user U is uncomfortable. I could give it. Therefore, it is desirable to set the switching period to about 1 to 2 seconds, for example. However, this does not limit the invention. The same applies to the second to fourth examples described below.

[3-2. Second example of content switching by display device]
Next, a second example of content switching by the display device 10 according to the present embodiment will be described with reference to FIGS. FIG. 9 is an explanatory diagram illustrating display positions in a second example of content switching by the display device according to the present embodiment. FIG. 10 is an explanatory diagram for explaining the sound image localization position in the second example of content switching by the display device according to the present embodiment. FIG. 11 is an explanatory diagram illustrating sound pressure in a second example of content switching by the display device according to the present embodiment. 12 and 13 are explanatory diagrams for explaining the concept of the second example of content switching by the display device according to the present embodiment.

(Display position)
First, the movement of the display position by the display control unit 15 will be described with reference to FIG.
In the second example, the display control unit 15 moves the video display position to the left. For example, when a certain video is displayed on the display screen M, the center of the display position of the video is moved from the center of the display screen M to the left. Similarly, the center of the display position of another video is moved from the right side of the display screen M to the center. Then, the user U recognizes as if the display images of both images have moved to the left. Conversely, when the center of the video display position is moved to the right, the user U recognizes that the display video has moved to the right. Utilizing this effect, the display control unit 15 moves the display position to the left (it is of course possible to move it to the right). This will be described more specifically.

  As shown in FIG. 9, it is assumed that the video is displayed so that the center of the display screen M of the display device 10 matches the center of the video of the viewing content A until the switching start timing t0. Then, it is assumed that the content switching starts at the switching start timing t0. Then, the center of the video of the viewing content A is moved to the left along the line L11, and the display position is also moved to the left of the user U (the positive x-axis direction in FIG. 1). As a result, the video of the viewing content A disappears from the display range to the left, and at the timing t1, the video of the viewing content A is completely moved out of the display range. At the same time, on the other hand, at the switching start timing t0, the center of the video of the switching content B is on the right side of the display screen M such that the video does not enter the display range, but gradually moves to the left along the line L12. Moved to. As a result, at the timing t1, the center of the video of the switching content B coincides with the center of the display screen M, and the video of the switching content B is displayed on the display screen M. That is, the viewing content A before switching moves to the left and disappears, while the switching content B after switching moves from the right and is displayed.

(Sound image localization position)
FIG. 10 shows an example of moving the localization position of the sound image.
As shown in FIG. 10, it is desirable that the localization position of the sound image is moved in the same direction and at the same speed as the movement of the display position shown in FIG.

(Sound pressure)
FIG. 11 shows changes in sound pressure of voice.
In this second example, the sound image localization position is moved to the left as shown in FIG. Therefore, for the viewing content A, the audio control unit 17 gradually increases the sound pressure of the left channel of the surround system, and conversely decreases the sound pressure of the right channel. In addition, for the switching content B, the audio control unit 17 makes the sound pressures of the right channel and the left channel equal from the state in which the sound pressure of the right channel is higher than the sound pressure of the left channel. Change to Then, an impression that the movement of the sound image localization position is performed more effectively can be given to the user U. However, FIG. 11 does not show such a difference in sound pressure between the left side and the right side, but representatively shows the average sound pressure of all channels.

  It is desirable that the sound pressure of the viewing content A is gradually decreased after the switching start timing t0, for example, as indicated by a line L13 (fade out). On the other hand, it is desirable that the sound pressure of the switching content B is gradually increased after the switching start timing t0, for example, as indicated by the line L14 (fade in). In this case, the sound of the viewing content A and the sound of the switching content B are cross-faded, and the sense of reality can be further increased.

(concept)
By adjusting the display position / sound image localization position / sound pressure as in the second example, the user U recognizes that the display device 10 performs the following content switching.

  That is, as shown in FIG. 12, the user U recognizes as if a plurality of contents are arranged in the left-right direction. In FIG. 12, the viewing content A is displayed on the display screen M. However, when the content is switched, as shown in FIG. 13, the video display position of the viewing content A, the localization position of the sound image of the sound, and the sound pressure are moved in the moving direction V2 to the left of the user U. As described above, the user U recognizes. Along with the movement of the viewing content A, the switched content B after switching moves from the right to the moving direction V2 and is displayed on the display screen M. Therefore, the user U has an impression that a plurality of contents are arranged in the left-right direction, and the arranged contents are turned in the left-right direction by switching the contents.

  As a further modification of the second example, it is of course possible to move the display position / sound image localization position / sound pressure vertically. In this case, it is desirable that no difference be added between the sound pressure of the left channel and the sound pressure of the right channel of the surround system.

[3-3. Third example of content switching by display device]
As described above, two examples of content switching according to the present embodiment have been described. However, as described above, content switching according to the present embodiment is not limited to these two examples. Therefore, the third example and the fourth example will be described as further examples of content switching. Note that changes in the display position, sound image localization position, and sound pressure in content switching have been described in detail in the first and second examples, so the following description will focus on the concepts in the third and fourth examples. However, it goes without saying that the third example and the fourth example can be realized by changing the display position, the sound image localization position, and the sound pressure with some changes from the first example and the second example.

  A third example of content switching by the display device 10 according to the present embodiment will be described with reference to FIGS. 14 and 15. 14 and 15 are explanatory diagrams for explaining the concept of the third example of content switching by the display device according to the present embodiment.

(concept)
In the third example, as shown in FIG. 14, a plurality of switchable contents are arranged in a substantially circular shape. Then, as shown in FIG. 15, the content is switched by rotating the display positions of the plurality of contents in the movement direction V3. The rotation of the display position and the like is performed by changing the display magnification by the display control unit 15, adjusting the vertical and horizontal adjustments of the center position of the image, superimposing the image, changing the sound image localization position by the audio control unit 17, changing the sound pressure, and the like. Is done. As a result, the user U recognizes that the display device 10 performs the following content switching.

  That is, as shown in FIG. 14, the user U recognizes the state in which a plurality of contents are arranged in a substantially circular shape as if viewed from diagonally above. In FIG. 14, the viewing content A is displayed near the center of the display screen M. However, when the content is switched, as shown in FIG. 15, the video display position, the sound image localization position, and the sound pressure of the plurality of contents including the viewing content A are moved in the movement direction V3. In addition, the user U recognizes. As a result, the content is switched by displaying the switched content B after switching almost in the vicinity of the center of the display screen M. Therefore, the user U has an impression that the arrangement positions of the plurality of contents and the sound source are rotated, and the plurality of contents arranged in a substantially circular shape are turned in the circle direction.

[3-4. Fourth example of content switching by display device]
Next, a fourth example of content switching by the display device 10 according to the present embodiment will be described with reference to FIGS. 16 and 17. 16 and 17 are explanatory diagrams for explaining the concept of a fourth example of content switching by the display device according to the present embodiment.

(concept)
The fourth example applies the movement in the horizontal direction and the movement in the vertical direction described in the second example, and moves the content as if it is a “cross media bar (registered trademark)”. Can be switched. As a result, the user U recognizes that the display device 10 performs the following content switching.

  That is, as shown in FIG. 16, the viewing content A is displayed substantially on the left side of the center, and other content (for example, content C) is arranged on the left and right, and other content (for example, content B) is also arranged on the top and bottom. It is done. It is desirable that the contents arranged in the left-right direction or the contents arranged in the up-down direction have some relationship such as having common attribute information. As such relevance, for example, the contents arranged in the left-right direction may be contents broadcast on each channel of terrestrial digital broadcasting. In this case, for example, contents arranged in the vertical direction may be different in broadcast format and acquisition method such as terrestrial analog, BS analog, BS digital, recorded content, and content on a network. However, various modifications can be considered for the classification based on such attribute information.

  Then, the user U recognizes as if a plurality of contents are arranged like a cross media bar (registered trademark). In FIG. 16, viewing content A is displayed at the center of the cross media bar (registered trademark). However, when the content is switched, as shown in FIG. 17, the display position of the video of the plurality of contents including the viewing content A, the localization position of the sound image of the sound and the sound pressure are moved in the moving direction V4, the moving direction V5, or The user U recognizes as if moved in the opposite direction. As a result, at the center of the cross media bar (registered trademark), for example, the switching content B is displayed as the content after switching, thereby switching the content. Therefore, the user U has the impression that the video and sound source of the content arranged in the shape of the cross media bar (registered trademark) have moved along the cross media bar (registered trademark).

[3-5. Example of determining content switching method]
As exemplified above, the display device 10 according to the present embodiment can perform content switching as in the first to fourth examples. On the other hand, as described above, the moving direction determination unit 13 determines which content switching method is used to switch the content. Therefore, here, an example of determining the switching method by the moving direction determining unit 13 will be described.

  As described above, the moving direction determination unit 13 can determine one direction set in advance as the moving direction, but the moving direction determination unit 13 moves based on at least one of the viewing content attribute information and the switching content attribute information. The direction can be determined. Therefore, here, determination of the moving direction based on the attribute information of both contents will be described.

  Examples of content attributes include: content type (genre), summary of content, etc., information on performers and producers, broadcast time zone and date, broadcast channel, date and date when content was created -Viewers targeted by the content-Information provided to viewers related to the content-Broadcast format, acquisition method, etc.

The movement direction determination unit 13 determines a movement direction according to the change in the attribute information.
For example, the movement direction determination unit 13 determines the movement direction in one direction when one attribute information changes before and after switching, and determines the other direction when other attribute information changes before and after switching. It is also possible to determine the moving direction. In this case, the user can be provided with information on which attribute information has changed in the content before and after switching. This case will be described below with a more specific example. However, the example given here is merely an example, and it goes without saying that various modifications can be considered.

For example, when the content is being broadcast, switching of the content includes switching to change the broadcasting format itself and switching of a simple channel within the same broadcasting format. Therefore, the moving direction determination unit 13 determines the moving direction V1 of the first example shown in FIG. 8 or the like when switching to change the broadcast format itself, while the switching direction is simply illustrated in FIG. You may determine to the moving direction V2 of 2nd example shown to 13 grade | etc.,. As a result, the user can know whether the content switching involves a change in broadcast format or a simple channel change. Also, in this case, unlike the fourth example shown in FIG. 17 and the like, the display device 10 is a content such as a cross media bar (registered trademark) in which the content is arranged horizontally on the front, back, left, and right of the user. A switching scheme can be provided.
In addition, for example, when the content is recorded in advance in a recording device (not shown), the movement direction determination unit 13 may switch the content shown in FIG. The moving direction V3 in the example may be determined. Further, in the case of switching between the content of the recording device and the content being broadcast, the movement direction determination unit 13 may determine the movement direction V4 of the fourth example shown in FIG.
With these examples and combinations thereof, the display device 10 can indicate to the user information regarding whether or not the broadcast format or acquisition method has been changed by the moving direction.

  On the other hand, here, a case has been described in which the attribute information is changed by the moving direction, but on the contrary, it is also possible to indicate which attribute information has not been changed by the moving direction. Needless to say.

  It is of course possible to determine the moving direction according to the attribute information such as the content category. For example, if the category “drama” is common, the movement direction determination unit 13 determines the movement direction V1 in the first example shown in FIG. 8 and the like, and if the category is changed, the movement direction determination unit 13 changes to FIG. It is also possible to determine the moving direction V2 in the second example shown. In this case, the moving direction determination unit 13 can determine the moving direction based on, for example, only the category of the switching destination content (switching content B). Can propose a new information providing method such as indicating the attribute information of the content after switching by its moving direction.

  Moreover, the moving direction determination part 13 can also determine the speed of the movement with a moving direction according to attribute information, for example. For example, if the category of the switching content is “sports” or the like, it is also possible to increase the speed of movement, that is, the inclination of the lines L1, L4, etc. in FIG. . In this case, it is possible to switch to a new content that reflects the attribute information of each content more realistically.

  Here, as an example of attribute information, the broadcast format, acquisition method, and content category have been described as examples. However, of course, the determination of the moving direction and the speed thereof are determined by other attribute information. It goes without saying that may be done.

[4. Example of effect by display device]
The display device 10 according to the first embodiment of the present invention has been described above.
According to the display device 10, since the content is switched while moving at least one of the content before and after switching, the content can be switched more smoothly. At this time, since the localization position of the sound image of the content is also moved together with the movement of the display position of the content, it is possible to switch the content with a sense of reality and a stereoscopic effect.

  For example, in the first and third examples shown in FIGS. 8 and 15 and the like, the content is also moved in the front-rear direction of the user. As a result, the realism and stereoscopic effect of content switching are further enhanced.

  As described above, according to the display device 10 according to the present embodiment, it is possible to provide a new user interface by moving the video and the sound image at the same time and further switching the content with a sense of presence and a stereoscopic effect. It is. At this time, by changing the moving direction according to the attribute information of the content, the attribute information can be provided to the user with a new visual and auditory effect as well as content switching with a sense of presence and a stereoscopic effect.

  As mentioned above, although preferred embodiment of this invention was described in detail, referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.

  For example, in the said embodiment, it demonstrated, giving the 1st example-the 4th example as an example of a moving direction. However, the moving direction is not limited to these examples as described above. For example, it is possible to move an image, a sound image, and the like in an oblique direction by combining up and down, left and right, combining front and rear, left and right, or up and down, and combining up and down, front and back, and left and right.

  For example, in FIG. 4 and the like, the case where the display position and the sound image localization position move at a constant speed has been described, but this speed may be changed during the movement. In other words, for example, when moving the display position or the like, it is needless to say that it is possible to change the display position so that it is faster at the start of movement and slower as it approaches the end of movement.

  In the above embodiment, the case where the sound pressure fades in and out is described. In the first example such as FIG. 8, the case where the viewing content A disappears at the timing t <b> 1 as illustrated in FIG. 4 is described. . However, this display image may gradually disappear or appear like fade-in / fade-out in sound pressure.

  In addition, the series of processes described in the above embodiments may be executed by dedicated hardware, but may be executed by software. When the series of processes is performed by software, the above series of processes can be realized by causing a general-purpose or dedicated computer to execute the program. The computer includes a CPU (Central Processing Unit), a recording device such as a HDD (Hard Disk Drive), a ROM (Read Only Memory), a RAM (Random Access Memory), a LAN (Local Area Network), etc. Communication devices, input devices such as a mouse / keyboard, magnetic disks such as flexible disks, optical disks such as various CDs (Compact Discs), MOs (Magneto Optical) disks, DVDs (Digital Versatile Discs), semiconductor memories, etc. Drives that read and write to removable storage media, etc., and display devices such as monitors, and audio from speakers and headphones An output device such as an output device. The computer may execute the above-described series of processes by executing a program recorded in a recording device / removable storage medium or a program acquired via a network.

  In this specification, the steps described in the flowcharts are executed in parallel or individually even if they are not necessarily processed in time series, as well as processes performed in time series in the described order. Including processing to be performed. Further, it goes without saying that the order can be appropriately changed even in the steps processed in time series.
