Description

The present invention relates to a terminal device and a program capable of outputting a plurality of types of contents with different output methods using an output device.

In recent years, a portable terminal device that can be freely carried can also view contents of a stereoscopic video (3D image) in addition to a planar video (2D image), and is a technology that enables 3D (three-dimensional) display without using special glasses. Are well-known stereoscopic image display methods (parallax barrier method and lenticular method) using the parallax between the left and right eyes. In order to properly view 3D display with this stereoscopic image display method, the position of the user's eyes (normal viewing position) with respect to the display screen is an important factor. That is, if the user's position deviates from a position where the stereoscopic display can be seen, the blurred image is visually recognized. Therefore, conventionally, there is a technique in which a 3D image is switched to a 2D image and displayed in order not to see a blurred image. (See Patent Document 1).
Japanese Patent Laid-Open No. 2004-153489

However, in the above-described prior art, the above-described display switching needs to be performed by the user himself / herself. For example, even if an image (3D image) of a television broadcast (3D broadcast) is received and viewed, the image is blurred. In some cases, the user has no choice but to continue watching the 3D image or switch to the 2D image. That is, when the viewing position of the user is naturally shifted, the viewing position may be corrected. However, when the viewing position has to be shifted for some reason, the blurred 3D image is continued to be viewed as it is. I had to switch to the image to see it. In this way, if you have to look far away from the display screen for some reason, on the contrary, if you can only watch it close to the display screen, such as in a crowded train, you should watch 3D broadcasting properly. However, even if 3D broadcasting was selected, it was useless. This is the same even when listening to 3D sound and stereo sound as well as 3D images.

When displaying a 3D image on the display panel 8a, the CPU 1 recognizes a captured image obtained by capturing the user's face with the in-camera 10 so as to acquire the positions of the left and right eyes with respect to the mobile phone device as the current position of the user. I have to. Further, the CPU 1 operates the autofocus function of the in-camera 10 to acquire the measurement result obtained by measuring the distance from the mobile phone device to the user as the current position of the user.

The TV broadcast receiving unit 12 receives terrestrial digital TV broadcasts for portable receivers such as mobile phones, and can receive electronic program guides (EPG) in addition to TV video and audio data. The TV broadcast receiving unit 12 is connected to a TV antenna and receives a broadcast unit (analog circuit unit) that extracts a broadcast signal. The received broadcast signal is demodulated by OFDM (orthogonal frequency division multiplexing) or multiplexed. It has a digital circuit section that separates video, audio, and data (character data) from a signal, decodes them, and decompresses compressed data. Television video data and character data are displayed on the display unit 8, and television audio data is output from the 3D sound unit 13.

The 3D sound unit 13 is, for example, an output device (speaker device) that can reproduce sound three-dimensionally by arranging two sound speakers (not shown) close to each other. In addition to the volume, a virtual sound source that reproduces spatial information such as the direction and distance of the sound is created, and an auditory stereoscopic effect is reproduced from the time difference, phase difference, and volume difference of the sound. The 3D sound unit 13 can generate 3D sound, generate stereo sound that divides sound into left and right, and generate monaural sound. That is, the 3D sound unit 13 can output a plurality of types of contents with different output methods, and can arbitrarily switch between a 3D sound mode, a stereo sound mode, and a monaural sound mode under the control of the CPU 1. 3D sound / stereo sound / monaural sound is generated according to the 3D sound mode, stereo sound mode, and monaural sound mode. Hereinafter, the display unit 8 and the 3D sound unit 13 are collectively referred to as an output device as necessary, and 3D images and 3D sounds are collectively referred to as 3D content.

3 and 4 are diagrams for explaining whether or not the positional relationship between the output devices 8 and 13 and the user is a predetermined positional relationship suitable for viewing the content when the content is reproduced. Is a diagram for explaining whether or not the positional relationship between the display panel 8a and the user is a predetermined positional relationship suitable for stereoscopic viewing of the 3D image when the 3D image is viewed. It is the figure which showed the state which is viewing the display screen 8a with a mobile telephone apparatus, and the front part (display panel 8a side) of a mobile telephone apparatus.
In FIG. 3, “UP” indicates the current position of the user facing the display panel 8a, and “RL” is suitable for stereoscopically viewing a 3D image at a distance from the display panel 8a to the user. “RA” indicates a predetermined positional relationship (within an appropriate range) suitable for stereoscopically viewing a 3D image at an angle at which the user views the display panel 8a. .

Here, whether or not the current position UP of the user is within an appropriate range suitable for stereoscopic viewing of the 3D image depends on whether the positions of the left and right eyes obtained by image recognition are within the appropriate range RA as described above. In addition to determining whether or not there is, the determination is made based on whether or not the distance to the user obtained by the autofocus function is within the appropriate range RL. Then, the CPU 1 specifies a 3D image or a 2D image as the type of content to be output based on the determination result described above. Then, the display mode (3D display mode / 2D display mode) of the display unit 8 is controlled so that the output method corresponds to the specified content type, or the specified type of content is displayed as a list as a selection candidate. I am doing so.

FIG. 4 is a diagram for explaining whether or not the positional relationship between the 3D sound unit 13 and the user is a predetermined positional relationship suitable for listening to the 3D sound when listening to the 3D sound.
“SR” indicates a predetermined positional relationship (within an appropriate range) suitable for listening to 3D sound, and by creating a virtual sound source RS in this sound field, three-dimensionally from the sound time difference, phase difference, volume difference, etc. This shows that, when a user's current position UP is out of an appropriate range SR suitable for listening to 3D sound, such a stereoscopic effect cannot be obtained.

Here, whether or not the current position UP of the user is within the SR within the appropriate range of the 3D sound depends on the positions of the left and right eyes obtained by the image recognition as described above and the user obtained by the autofocus function. The determination is made based on whether the distance is within the appropriate range SR. Then, the CPU 1 specifies the type of content to be output (for example, 3D sound / 2D sound / monochrome sound) based on the determination result described above. Then, the output mode (3D sound mode / 2D sound mode / monochrome sound mode) of the 3D sound unit 13 is controlled so that the output method corresponds to the specified content type.

Next, the operation concept of the mobile phone device according to the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This also applies to other embodiments described later, and in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium.
5 and 6 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device. When the flow of FIG. 5 and FIG. Return to the main flow of operation (not shown).

FIG. 5 and FIG. 6 are flowcharts showing content reproduction processing that is started when content reproduction is instructed by a user operation.
First, if it is video content (image content) that is selected as a reproduction target (YES in step A1), the CPU 1 acquires the current position of the user and a predetermined position suitable for stereoscopically viewing a 3D image. It is checked whether or not there is a relationship (whether or not the position is within an appropriate range) (step A2).

That is, the in-camera 10 is activated to capture a photographed image of the user's face, and the right and left eye positions relative to the display panel 8a are acquired as the user's current position by recognizing the contents of the image. 10 is operated, and the measurement result obtained by measuring the distance from the display panel 8a to the user is acquired as the current position of the user. Then, it is checked whether or not the positional relationship between the current position UP of the user and the display panel 8a is within an appropriate range suitable for stereoscopic viewing of the 3D image. In this case, it is checked whether the left and right eye positions obtained by the above-described image recognition are within the proper range RA, and whether the distance to the user obtained by the autofocus function is within the proper range RL.

As described above, when one or both of the angle and the distance are out of the corresponding appropriate range (NO in step A3) as a result of determining whether the 3D display is within the appropriate range prior to the display of the 3D image (NO in step A3), the content After specifying the 2D content type as the output target (reproduction target) as the type (step A12), each 2D content belonging to this 2D content type is specified and its name is displayed in a list (step A13).

When a desired content is selected from the list screen by a user operation (YES in Step A14), the selected content is read (Step A16), and the display mode of the display unit 8 is switched to the 2D display mode ( Step A17). In this state, the content reproduction is started and the video content is displayed on the display unit 8 (step A10). Thereafter, until the end of the content reproduction is instructed by the user (YES in step A11), the above-described step A10 is performed. Return and continue playing the content.

As described above, if the user position is out of the appropriate range of the 3D image, 2D content is reproduced. If within the appropriate range (YES in step A3), the 2D content type is output as the content type. Specify (step A4). Then, after specifying each 3D content belonging to the 3D content type and displaying a list of the names (step A5), when a desired content is selected from the list screen by a user operation (YES in step A6). The selected content is read (step A8), and the display mode of the display unit 8 is switched to the 3D display mode (step A9). In this state, the content reproduction is started and the video content is displayed on the display unit 8 (step A10). Thereafter, until the end of the content reproduction is instructed (YES in step A11), the process returns to the above-described step A10. Continue to play the content.

In addition, when the 3D content list screen as described above is displayed (step A5), when a user operation requesting a change in content type is performed (YES in step A7), the process proceeds to step A13 described above. To display a list screen of 2D contents. In addition, when the 2D content list screen is displayed (step A13), when a user operation requesting the change of the content type is performed (YES in step A15), guide information that guides the user within the 3D appropriate range. Is displayed on the display unit 8 (step A18).

FIG. 7 exemplifies guide display in the appropriate range of 3D content, and displays a right eye guide frame that aligns the user's right eye position and a left eye guide frame that aligns the left eye position. The user moves so as to fit both eyes into the corresponding guide frame with reference to the guide display. When the position of the user falls within the appropriate 3D range (YES in step A19), the process proceeds to step A4 described above to display a 3D content list screen.

On the other hand, when reproduction of music content is instructed (NO in step A1), the flow proceeds to the flow of FIG. 5 to acquire the current position of the user, and the positional relationship between the user position UP and the 3D sound unit 13 is 3D. It is checked whether or not a predetermined positional relationship suitable for listening to the sound is present (whether or not the position is within an appropriate range) (step A20). That is, the in-camera 10 is activated to capture a captured image of the user's face, and the right and left eye positions relative to the mobile phone device are acquired as the user's current position by recognizing the contents of the image. The measurement result obtained by measuring the distance from the mobile phone device to the user is acquired as the current position of the user by operating the 10 autofocus function. Then, it is checked whether the positional relationship between the current position UP of the user and the 3D sound unit 13 is within an appropriate range suitable for listening to the 3D sound.

As a result, if both the angle and the distance are within appropriate ranges (YES in step A21), the 3D content type is specified as the output target (reproduction target) as the content type (step A22), and the 3D sound is appropriate. If it is out of range (NO in step A21), whether or not the positional relationship between the current position UP of the user and the 3D sound unit 13 is a predetermined positional relationship suitable for listening to stereo sound (within an appropriate range). (Step A23). If it is within the proper range of stereo sound (YES in step A23), the stereo content type is specified as the output target (reproduction target) as the content type (step A24), but within the proper range of 3D sound and stereo sound. If not (NO in step A23), the monaural content type is specified as the output target (reproduction target) as the content type (step A25).

After specifying the content type to be output in this way, each content belonging to this content type is designated and its name is displayed in a list (step A26), and then the desired content is selected from the list screen. When selected by operation (YES in step A27), the type of the selected content is determined. When 3D content is selected (YES in step A28), it is checked whether the 3D content type is specified (step A29). Now, when the 3D content type is specified in step A22, the output mode of the 3D sound unit 13 is switched to the 3D sound mode (step A30).

When the 3D content type is selected in a state where the 3D content type is not specified (NO in step A29), the user position is out of the appropriate range of the 3D content. Is displayed (see FIG. 7) (step A31). As a result, when the user's position falls within the appropriate 3D range (YES in step A32), the output mode of the 3D sound unit 13 is switched to the 3D sound mode (step A30). In the state of switching to the 3D sound mode in this way, content playback is started, and after 3D music content is output from the 3D sound unit 13 (step A33), hereinafter, until the end of content playback is instructed (step A33). In step A34, YES), the process returns to step A33 described above, and the content continues to be reproduced.

If the content selected by the user operation is stereo content (YES in step A35), it is checked whether the stereo type is specified (step A36). If the stereo type is specified in step A24 described above, the stereo sound mode is switched to the output mode of the 3D sound unit 13 (step A37). When the stereo content type is selected in a state where the stereo type is not specified (NO in step A36), the user position is out of the appropriate range of the stereo sound. Display is performed (step A38). As a result, when the user's position falls within the appropriate range of stereo sound (YES in step A39), the output mode of the 3D sound unit 13 is switched to the stereo sound mode (step A37). In this state, the content reproduction is started and the music content (stereo content) is output from the 3D sound unit 13 (step A33). Thereafter, the content reproduction is instructed (YES in step A34). Keep playing.

If the content selected by the user operation is monaural content (NO in step A35), the output mode of the 3D sound unit 13 is switched to the monaural sound mode (step A40). In this state, the content reproduction is started and the music content (monaural content) is output from the 3D sound unit 13 (step A33). Thereafter, the content reproduction is instructed (YES in step A34). Keep playing.

As described above, in the first embodiment, the CPU 1 has a positional relationship between the output device (display unit 8 and 3D sound unit 13) capable of outputting a plurality of types of content having different output methods and the user depending on the type of content. Since it is determined whether or not it is in a predetermined positional relationship and the type of content to be output is specified based on the determination result, content of an appropriate type is output according to the positional relationship between the output device and the user It is possible to quickly specify the target, and it is possible to output content of a type suitable for the user's situation without requiring a special operation from the user.

When selecting a content desired by the user from among a plurality of types of content as an output target, the content of the type specified according to the user's position is displayed as a list of candidates, and the user desires from the list display. Since content is selected as an output target, it is possible to easily select content that matches the user's situation.

When a change to a content type different from the content type specified according to the user's position is requested, the type of content whose output relationship between the output devices 8 and 13 and the user is requested to be changed is output. Since the positional relationship is displayed as a guide so that the positional relationship is suitable for the user, the user can adjust the position according to the guide display and can quickly change the type of content. Correspondence becomes possible.

When a content desired by a user is selected as an output target from among a plurality of types of content, if it is determined that the type of the selected content is different from the type of the specified content, this is notified. As a result, the user can adjust the position in accordance with the notification.

The display unit 8 can output a plurality of types of content (3D content / 2D content) with different output methods, and the positional relationship between the display unit 8 and the user has a positional relationship suitable for stereoscopic viewing of the 3D content. If so, the 3D content type is specified as the content type, so that the 3D content can always be viewed appropriately.

The 3D sound unit 13 is a speaker device that can output stereo sound and 3D sound. If the positional relationship with the 3D sound unit 13 is suitable for listening to stereo sound or 3D sound, the 3D sound unit 13 is a type of content. Since the content type of stereo sound or 3D sound is specified, stereo sound or 3D sound can always be heard properly.

The output devices 8 and 13 are controlled so that the output method corresponds to the type of content specified according to the position of the user, and the 2D display mode / 3D display mode, stereo sound mode / 3D sound mode / monaural sound mode are set. Since switching is performed, the modes of the output devices 8 and 13 can be controlled in conjunction with the position of the user.

Although the description is omitted in the first embodiment described above, when a content desired by the user is selected as an output target from among a plurality of types of content, the type of the selected content is determined by the position of the user. The output devices 8 and 13 are controlled so that the output method corresponds to the specified content type when it is determined that the content type is different. Then, the output mode or the like may be switched. For example, in the state where 3D content is specified as the content type, even if 2D content is selected, the mode may be switched to the 3D display mode or the 3D sound mode. As a result, even if content that does not match the user's situation is selected, it can be ignored.

In the first embodiment described above, image and music content are exemplified as the content. However, the content may be a content of a broadcast reception program or a broadcast reception channel, and the content type (2D) specified according to the position of the user. A program or channel corresponding to (broadcast, 3D broadcast) may be selected. Accordingly, it is possible to view a television broadcast that matches the user's situation.

(Embodiment 2)
A second embodiment of the present invention will be described below with reference to FIGS.

B4).

When the 2D broadcast is received (NO in step B4), the process proceeds to step B16, the display mode of the display unit 8 is switched to the 2D display mode, and then the process proceeds to the flow of FIG. 9 to display the received 2D broadcast (2D image). (Step B17). Although not shown, if the received 2D broadcast is a stereo sound, the stereo sound mode is generated and output after switching to the stereo sound mode as the output mode of the 3D sound unit 13 (hereinafter the same). When any operation is performed in the state where the broadcast content is output in this way (YES in step B18), it is examined what operation has been performed (steps B19, B21, B22). That is, it is checked whether the operation is a channel change operation (step B19), an operation for instructing viewing of the program guide (step B21), or an operation for instructing the end of reception of the television broadcast (step B22).

Now, when a channel change operation is performed (YES in step B19), after performing a channel selection process (channel change process) (step B20), the process returns to step B2 of FIG. When an operation other than the table browsing operation and the reception end operation is performed (NO in step B22), for example, a volume adjustment process, a recording process, etc. are performed as a process corresponding to the operation (step B23), and the reception end operation is performed. If it is interrupted (YES in step B22), the process returns to the main flow described above.

On the other hand, if the received broadcast is a 3D broadcast (YES in step B4 in FIG. 8), the user's current position is acquired before the display of the 3D broadcast is started, and the user position is suitable for the 3D broadcast. It is checked whether it is within the proper range (step B5). That is, the in-camera 10 is activated to capture a photographed image of the user's face, and the right and left eye positions relative to the display panel 8a are acquired as the user's current position by recognizing the contents of the image. 10 is operated, the measurement result obtained by measuring the distance from the display panel 8a to the user is acquired as the current position of the user, and it is checked whether the user position is within an appropriate range suitable for 3D broadcasting.

As a result, if it is within the appropriate range of 3D broadcasting (YES in step B6), 3D broadcasting is specified as an output target as the type of content (step B7). And after switching the display mode of the display part 8 to 3D display mode (step B12), the received 3D broadcast is displayed (step B17 of FIG. 9). Although not shown, if the received 3D broadcast is a stereo sound, the 3D sound unit 13 is switched to the 3D sound mode as the output mode, and then the 3D sound is generated and output (the same applies hereinafter). Thereafter, as in the case described above, an operation waiting state is entered.

If the user position is out of the appropriate range of 3D broadcasting (NO in step B6 in FIG. 8), guide display (see FIG. 7) to the appropriate 3D range is performed to correct it (step B8). ) Check whether a change from 3D broadcast to 2D broadcast is instructed by a user operation (step B9). If no change to 2D broadcast is instructed, whether the user's current position is acquired and within the appropriate range of 3D broadcast It is checked whether or not (step B10). If it is within the appropriate range (YES in step B11), after switching to the 3D display mode (step B12), the received 3D broadcast is displayed (step B17 in FIG. 9).

When an instruction to change to 2D broadcasting is given (YES in step B9 in FIG. 8), 2D broadcasting is specified as an output target as a content type (step B13). Then, the program table acquired in advance is accessed to search for programs whose content type is 2D broadcast (step B14), and a predetermined program is automatically selected from the corresponding 2D broadcast programs (step B15). For example, after selecting a program broadcast on a default channel or a program broadcast on a favorite channel designated in advance, the mode is switched to the 2D display mode (step B16) and the selected program is displayed (step B17 in FIG. 9). ).

On the other hand, when the program guide browsing operation is performed (YES in step B21 in FIG. 9), after displaying the program list (step B24), the current position of the user is acquired, and the user position is appropriate for 3D broadcasting. It is checked whether or not it is within the range (step B25), and if it is within the appropriate range (YES in step B26), 3D broadcast is specified as the output target as the content type (step B27) and is outside the appropriate range of 3D broadcast If so (NO in step B26), 3D broadcast is specified as the output target as the content type (step B28).

In this state, when a program desired by the user is selected from the program list screen (step B29), the content type of the selected program is acquired (step B30), and it is checked whether the selected program is a 3D broadcast ( Step B31) If the program is not a 3D broadcast program, after switching to the 2D display mode (Step B34), the received 2D broadcast is displayed (Step B17). If the selected program is a 3D broadcast program (YES in step B31), after switching to the 3D display mode on condition that the 3D broadcast is specified as an output target in step B27 described above (step B32). (Step B33) The received 3D broadcast is displayed (Step B17), but if the 3D broadcast is not specified as an output target (NO in Step B31), it is received after switching to the 2D display mode (Step B34). The 2D broadcast is displayed (step B17).

As described above, in the second embodiment, the CPU 1 acquires the positional relationship between the user and the output device (display unit 8, 3D sound unit 13) that can output a plurality of types of content with different output methods, and the plurality of types. Since the type of content selected as an output target is acquired from the types of content and predetermined processing is executed based on the positional relationship and the content type, the positional relationship between the output device and the user is determined. In addition, it is possible to output an appropriate type of content, and it is possible to output a type of content suitable for the user's situation without requiring a special operation from the user.

Since the positional relationship between the output device and the user is acquired when the type of content selected as the output target is a predetermined type (for example, 3D broadcasting), the user's position is not constantly monitored. By only acquiring the user position as necessary, it is possible to output content of a type suitable for the user's situation.

Determining whether the positional relationship between the output device and the user is suitable for outputting the predetermined type of content when the type of content selected as the output target is a predetermined type (for example, 3D broadcasting) Since the predetermined process is executed according to the result, the process can be executed only when a predetermined type of content is selected.
