Description

The present invention relates to a broadcast receiving terminal device and a program capable of receiving television broadcast data.

In recent years, as a technology capable of 3D (three-dimensional) display without using glasses, a stereoscopic image display method (parallax barrier method or lenticular method) using parallax between the left and right eyes is well known. In order to enable proper visual recognition, 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.

For example, when the telephone function (voice telephone function), the e-mail function, and the Internet connection function are operated, the telephone base unit (not shown) Is a telephone communication means for transmitting and receiving data between them, and when a voice telephone function is operated, a signal is taken in from the receiving side of the baseband unit and demodulated into a received baseband signal, and then a speaker for communication through the voice signal processing unit 6 The audio is output from the SP, and the input audio data from the call microphone MC is acquired from the audio signal processing unit 6 and encoded into a transmission baseband signal, which is then given to the transmission side of the baseband unit and output from the antenna. . The operation unit 7 performs dial input, character input, command input, and the like. When a TV broadcast reception start / end operation, channel change operation, or the like is performed, the CPU 1 performs processing according to an input signal from the operation unit 7. Execute.

The display unit 8 has a display screen (liquid crystal display panel) using a high-definition liquid crystal, and displays a television image, character information, image information, a standby image, and the like. (Dimension) display is possible. FIG. 2 is a diagram for explaining a display screen that constitutes the display unit 8, and a backlight 8 b that illuminates the display panel 8 a that constitutes the display screen is disposed on the front surface thereof. On the side, a parallax barrier 8c for displaying 3D images is provided. The parallax barrier 8c is provided with a plurality of slits 8d formed at equal intervals, and when the user's eyes are in an appropriate position (within an appropriate range) with respect to the display panel 8a, the parallax barrier 8c. By visualizing the display panel 8a through the slit 8d, stereoscopic vision is obtained by the binocular parallax, and the slit 8d of the parallax barrier 8c is electrically formed or eliminated. .

The display unit 8 is configured to be able to switch between 2D (two-dimensional) image display and 3D image display, and in response to a 2D display / 3D display switching command from the CPU 1, the slit 8d of the parallax barrier 8c.

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

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. When the television broadcast receiving unit 12 receives 3D video (3D image) as the television broadcast data, the CPU 1 displays the 3D image on the display unit 8. At this time, the current position of the user facing the display panel 8 a is displayed. It is determined whether or not the current position is within an appropriate range suitable for stereoscopic viewing of the 3D image, and display and recording of the 3D image are controlled based on the determination result.

FIG. 3 shows that when a 3D image is displayed on the display panel 8a, the current position of the user facing the display panel 8a is within an appropriate range suitable for stereoscopic viewing of the 3D image. It is a figure for demonstrating notion how image display and video recording are controlled.
In the figure, “UP” indicates the current position of the user facing the display panel 8a, and “RL” is a predetermined position suitable for stereoscopically viewing a 3D image at a distance from the display panel 8a to the user. “RA” indicates a predetermined positional relationship (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.

FIG. 3 illustrates how the user's current position is controlled depending on whether or not the user's current position is within the appropriate range RA relating to the angle, and whether or not the user's current position is within the appropriate range RL relating to the distance. Since the corresponding control is the same as that in the case of the appropriate range RA regarding the angle, it is not shown. Here, when starting the display of the 3D image and after starting the display, the CPU 1 determines whether or not the user's current position is within the appropriate range, and the user's current position (angle) is within the appropriate range. If it is within the RA, the 3D image is displayed, but if it falls outside the appropriate range RA and becomes an inappropriate range, this 3D image is converted into a 2D image and displayed, and the 3D image received thereafter is recorded. I try to let them.

When the current position of the user returns from the inappropriate range to the appropriate range RA, the 2D image is switched to the 3D image, and the recorded content is chased and reproduced while recording the 3D image. Thus, in the present embodiment, not only the response when the user position is out of the appropriate range during viewing of the 3D broadcast, but also the response when the user position is not in the appropriate range from the beginning (at the start of reception of the 3D broadcast) is considered. ing.

Next, the operation concept of the mobile phone device in this 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. That is, 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. 4 to 6 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the overall operation of the mobile phone device. When the flow of FIGS. Return to the main flow of operation (not shown).

4 to 6 are flowcharts showing a TV broadcast reception process started to be executed in response to a user operation instructing the start of television (TV) broadcast reception.
First, after activating the television broadcast receiving unit 12, the CPU 1 selects a channel (selects the previous channel as a default when reception starts) (step S1 in FIG. 4), and receives a television broadcast of the selected channel. (Step S2) Whether it is 3D broadcasting is checked (Step S3). When a 2D broadcast is received (NO in step S3), the process proceeds to 2D broadcast reception display processing, and after displaying the received 2D broadcast (2D image) (step S4), it is checked whether a channel change operation has been performed. Or (step S5), it is checked whether the end operation for instructing the end of the reception of the television broadcast has been performed (step S6). If a channel change operation is performed (YES in step S5), the process returns to step S1 to perform channel selection processing (channel change processing). When a television broadcast reception end operation is performed (YES in step S6), the TV broadcast reception process in FIGS. 4 to 6 ends.

If the received television broadcast is a 3D broadcast (YES in step S3), prior to the display of the 3D broadcast, the current position of the user facing the display panel 8a is acquired, and the user position is a stereoscopic view of the 3D image. It is checked whether it is within an appropriate range suitable for performing (step S7). 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 the appropriate range of 3D broadcasting. 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 as a result of determining whether the 3D broadcast is within the appropriate range prior to the display of the 3D broadcast (NO in step S8), FIG. Then, the flow proceeds to step 5 to start an operation of recording (including recording) the received 3D broadcast (step S14). In this case, the received 3D broadcast is sequentially captured and recorded in the 3D broadcast recording unit RM. At this time, the 3D image is converted into a 2D image and displayed on the display panel 8a (step S15). Until the channel change operation is performed (step S16) or the end operation for instructing the end of the reception of the television broadcast is performed (step S19), the CPU 1 records the 3D broadcast as a 2D image. Display converted to.

In this state, when a channel change operation is performed (YES in step S16), the recording operation is terminated (step S17), and the 3D broadcast is recorded because it is out of the proper range of the 3D broadcast. Is displayed (step S18). And it returns to step S1 of FIG. 4 and performs a channel selection process (channel change process). When an end operation for instructing the end of the reception of the television broadcast is performed (YES in step S19 in FIG. 5), the recording operation is ended (step S20), and the recording presence icon is displayed (step S20). Step S21). Thereafter, the TV broadcast reception process of FIGS.

Prior to displaying the 3D broadcast, if both the angle and the distance are within the proper range as a result of determining whether or not the 3D broadcast is within the proper range (YES in step S8 in FIG. 4), the 3D broadcast is received. The display process is started, and the received 3D broadcast (3D image) is displayed on the display panel 8a (step S9). When performing 3D display, the brightness of the backlight 8b is set higher than that of normal display (2D display) in order to make the stereoscopic view easier to see. Even after the display of the 3D image is started, the current position of the user is acquired and it is checked whether it is within an appropriate range suitable for stereoscopic viewing of the 3D image (step S10).

If it remains within the appropriate range of 3D broadcasting (YES in step S11), it is checked whether a channel change operation has been performed (step S12), or whether a termination operation instructing the end of reception of a television broadcast has been performed. (Step S13). If no channel change operation or end operation is performed (NO in step S13), the process returns to the above step S9 to continue displaying the 3D image as it is, but when the channel change operation is performed (YES in step S12). ) Returning to the above-described step S1, channel selection processing (channel change processing) is performed, and when a television broadcast reception end operation is performed (YES in step S13), the end of the TV broadcast reception processing of FIGS. Become.

Then, after starting the display of the 3D image, if the current position of the user deviates from the appropriate range of 3D broadcasting (NO in step S11), the flow proceeds to the flow of FIG. 6, and the user position is changed from the appropriate range to the inappropriate position. In addition to notifying the deviation (step S22), the received 3D broadcast is taken in and a recording operation for recording in the 3D broadcast recording unit RM is started (step S23). After the brightness of the backlight 8b is lowered (step S24), the 3D image is converted into a 2D image and displayed on the display panel 8a to switch from 3D display to 2D display (step S25).

Note that, as described above, the brightness of the backlight 8b is set higher than that during normal 2D display in order to make the stereoscopic view easier to view during 3D display. Therefore, when switching from 3D display to 2D display, the backlight 8b In addition to lowering the brightness of the display to the normal state, the user may not be looking at the display panel 8a, so the brightness is reduced to reduce power consumption, and the user is informed that it is out of the proper range. In order to arouse the brightness, the brightness is reduced.

As described above, when the 3D broadcast is shifted from an appropriate range to an inappropriate position during viewing of the 3D broadcast, the 3D image is converted into a 2D image while recording the 3D broadcast. The 3D broadcast is recorded and converted into a 2D image. Is continued until the user notices that the position is incorrect. That is, after recording of 3D broadcast is started and converted to 2D image is displayed (step S25), the current position of the user is acquired and checked whether it is within the proper range of 3D broadcast (step S26). If it remains off (NO in step S27), the process returns to the above-described step S25 to continue recording of 3D broadcast and conversion display to 2D image.

Now, when the user notices that the position is inadequate due to an alarm notification or when there is no problem in viewing in the appropriate range, when the user's position returns from the inappropriate position to the appropriate range ( YES in step S27), a message for inquiring whether to reproduce the recorded content of the 3D broadcast automatically recorded as described above is displayed on the display screen 8 (step S28). In this case, when a response operation for rejecting the reproduction is performed (NO in step S29), the process returns to step S9 in FIG. 4 to display the 3D image, but when a response operation for affirming the reproduction is performed (in step S29). (YES) The recorded content of the 3D broadcast recording unit RM is read, and chasing playback (fast forward playback) is started (step S30). This chasing playback (fast-forward playback) is to record the received 3D broadcast, for example, to play back at 1.3 times speed, or to scan and play a commercial part, and this is displayed on the display panel 8a. As a result of the fast-forward playback from the 3D recording contents when it deviates from the appropriate range to the inappropriate position, the playback position catches up with the recording position.

Even during such chasing playback, the current position of the user is acquired and it is checked whether it is within the appropriate range of 3D broadcasting (step S31). If it deviates from the appropriate range during chasing playback (NO in step S32), after stopping the playback of the 3C image (step S34), the process returns to the above-described step S31 and remains in a stopped state until it returns to the appropriate range. . If the current position of the user is within the appropriate range during chasing playback (YES in step S32), the current playback position is compared with the current recording position to check whether the playback position has caught up with the recording position (step S33). ) Until the playback position catches up with the recording position, the process returns to step S30 to continue the chasing playback. When the playback position catches up with the recording position (YES in step S33), the process returns to step S9 in FIG. To 3D display currently being broadcast.

As described above, in this embodiment, when the television broadcast receiving unit 12 receives a 3D image as the television broadcast data, the CPU 1 displays the 3D image on the display panel 8a. At this time, the display panel 8a displays the 3D image. Since it is determined whether or not the current position of the opposing user is within an appropriate range suitable for stereoscopic viewing of the 3D image, the display and recording of the 3D image are controlled based on the determination result. For example, even if the user is in a position where the 3D image cannot be satisfactorily viewed stereoscopically, the user can view the 3D image later without requiring a special operation from the user, improving the operability and overlooking the 3D image. It can be effectively prevented. For example, when the user is in a situation or position where the user cannot reliably view the 3D broadcast, the recorded content can be viewed, and when the user is in a position or situation where the user can stereoscopically view the 3D image, the received 3D broadcast is viewed. be able to.

If the user's current position is within the appropriate range, the 3D image is displayed on the display panel 8a. If the user's current position is out of the proper range, the 3D image is recorded. For example, the viewing position must be shifted for some reason. In such a case, conventionally, it is only possible to continue to view the blurred 3D image as it is or to switch to the 2D image, but in this embodiment, the 3D image can be viewed at a convenient time for the user.

If the current position of the user is within the proper range when starting the display of the 3D image, the 3D image is displayed on the display panel 8a. If the user is out of the proper range after starting the display of the 3D image, the 3D received thereafter Since the image is recorded, for example, even when the position of the user moves while viewing the 3D image, appropriate control can be performed accordingly.

If the current position of the user is within the proper range when starting the display of the 3D image, the 3D image is displayed on the display panel 8a. If the user is out of the proper range after starting the display of the 3D image, the 3D received thereafter In addition to recording an image, when the recording returns to the appropriate range after the start of recording, the recorded content is played back. For example, even if the position of the user moves while viewing a 3D image, In addition to being able to perform appropriate control, it is possible to view the recorded content while it is out of the proper range immediately after returning to the proper range.

When the current position of the user is out of the appropriate range, the 2D image obtained by 2D conversion of the 3D image is switched and displayed on the display panel 8a in place of the 3D image. In such a case, a 2D image that is clearer than the blurred 3D image can be seen, which is in accordance with the actual situation.

When switching and displaying 2D images instead of 3D images on the display panel 8a, the brightness of the backlight that illuminates the display panel 8a is reduced, so that power consumption can be reduced and the display is out of the proper range. Can be alerted to the user.

When the current position of the user returns to the appropriate range after switching the 2D image instead of the 3D image to be displayed on the display panel 8a, the 3D image is displayed instead of the 2D image. Followed 3D display is possible. As a result, when chasing playback is not desired, it is possible to view the 3D broadcast being received.

When the user's current position is out of the proper range when starting the display of the 3D image, the recording of the 3D image is started. Therefore, when the user's position moves while viewing the 3D image. Not limited to this, appropriate control is possible even at the start of display. That is, not only when the user position deviates from the appropriate range during viewing of the 3D broadcast, but also when the user position is not within the appropriate range from the beginning (at the start of reception of the 3D broadcast).

When the recording of the 3D image is started, the 2D image obtained by converting the 3D image into 2D is displayed on the display panel 8a instead of the 3D image, so that the viewing position must be shifted for some reason. Besides being effective, 3D images can be viewed freely at any time thereafter.

Since the CPU 1 determines whether or not the received television broadcast data is a 3D broadcast including a 3D image, the CPU 1 determines whether or not the current position of the user is within an appropriate range when the 3D broadcast is received. In response to receiving the 3D broadcast, it can be determined whether or not the user's position is appropriate.

Since the captured image obtained by capturing the user facing the display panel 8a is recognized and the positions of the left and right eyes are acquired as the current position of the user to determine whether they are within the appropriate range, the appropriate range is It is related to the angle viewed by the user with respect to the display panel 8a, and it can be determined whether or not the angle is appropriate.

Since 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 is determined to be within the appropriate range, the appropriate range is the distance from the display panel 8a to the user. It is possible to determine whether or not the distance is appropriate.

In the above-described embodiment, the captured image obtained by capturing the user is recognized, and the positions of the left and right eyes are acquired as the current position of the user to determine whether they are within the appropriate range. Whether or not the user is facing the panel 8a may be measured by an autofocus function to determine whether or not the user is within an appropriate range. In this case, if the user is facing directly, it can be determined that it is within the appropriate range.

In the above-described embodiment, the left and right eye positions are detected as the current position. However, the present invention is not limited to the eye position, and may be a nose position, an ear position, or the like. If the specified boundary is the position of the nose, it may be within the appropriate range.
