  A TV receiver that receives broadcasts has a videophone function added, so a TV receiver that can be placed in the living room is the best form, but only the shape is different, and the essence is the same digital tuner or It can be realized with a DVD recorder, a mobile phone, a personal computer, etc., and is not particularly specified.

  FIG. 1 is an overall block diagram of a television with a videophone function according to a first embodiment of the present invention. 1 is a TV with a videophone function, 2 is a display panel, 3 is an antenna, 4 is a broadcast tuner, 5 is a decoder, 6 is a speaker, 7 is a CPU, 8 is an HTML browser, 9 is an incoming call detection means, and 10 is externally connected through a network. NW I / F that communicates with, 11 is a remote controller, 12 is a storage, 13 is a camera, 14 is a microphone, 15 is an encoder, 16 is a network, and 17 is a remote control receiver.

  The mechanism of the TV with videophone function in FIG. 1 will be described. The standard function is to receive and display a television broadcast as a standard function. The digital television broadcast received by the antenna 3 is sent to the broadcast tuner 4, and the selected one is sent to the decoder 5. The decoder 5 extracts the video and audio data by decompressing or decoding the video wave compressed broadcast wave, and sends the video to the display panel 2 and the audio to the speaker 6 to display the video and output the audio. . When the user performs an operation using the remote controller 11, the remote control receiving unit 17 receives the instruction, the CPU 7 interprets it, and controls various parts in the TV 1 with the videophone function.

  Next, the videophone function will be described. When the videophone function is in operation, it is necessary to send the near-site video and audio to the other party. Therefore, video is input by the camera 13 and audio is input by the microphone 14, video is compressed by the encoder 15, and output to the network 16 through the NW I / F 10.

  The same operation is also performed on the TV with the videophone function of the other party, and the video compression information in which the video and audio sent through the network 16 are compressed is sent to the decoder 5, and the display panel 2 is subjected to the decoding operation. Is displayed. As a result of the above operation, the videophone function is realized by displaying and outputting the other party's video and audio on this side, and displaying and outputting the other side's video and audio on the other side. The operation at the start of use of the videophone function or the operation when an incoming call is received will be described later.

  FIG. 2 is an external view of the television 1 with a camera built-in videophone function described with reference to FIG. In each function installation location, for example, speakers 6 are installed on the left and right sides of the TV 1 with a videophone function, and a camera 13 is embedded in the middle. Further, the microphone 14 is set at the upper middle. The user uses the remote control 11 to operate the television 1 with a videophone function.

  Here, the camera was placed at the bottom, considering the total height of today's large-sized TV, with the user sitting on the sofa in the living room, as with the microphone 14, if it was placed on the top, , The video looks down on the user, and is not very suitable as video to be sent to the other party as a videophone. Therefore, the lower side was used. The reason why the microphone 14 is set to the upper side is that the vibration of the speaker 6 is picked up near the speaker 6 and the performance deteriorates.

  FIG. 3 is a system configuration diagram in the embodiment of FIG. 13, in which 21 is a videophone server, 22 is a VOD server, 23 is a TV with a videophone function, and is equivalent to the TV 1 with a videophone function.

  In FIG. 3, a system is constructed on an IP network in order to realize a videophone call, and the TV 1 with a TV phone function and the TV 23 with a TV phone function are connected through a network 16. The videophone server 21 is prepared so that the TVs 1 and 23 with a videophone function can easily find each other. The VOD server 22 schematically shows that the VOD service is provided on the same network.

FIG. 4 is an external view of the remote controller 11, 31 is a power button, 32 is a TV button, 33 is a VOD button, 34 is a videophone button, 35 is a stop button, 36 is a camera orientation setting button, and 37 is a menu shift. Direction buttons are cross keys.
The user operates the television 1 with the videophone function described with reference to FIG.

  FIG. 5 summarizes the VOD and telephone processing procedures in a table. This table shows that the processing from item numbers 1 to 7 is performed for the VOD processing and the telephone processing. First, the VOD process in FIG. 5 will be described sequentially. The operation of the remote controller will be described using the remote controller 11 described with reference to FIG. 3 for the system operation, and for the actual internal operation, the movement of the entire block diagram of FIG. This will be described with reference to individual figures.

  In FIG. 5, to perform VOD processing, in item No. 1, the user presses the power button 31 of the remote controller 11. When the power is already on, it is not necessary to press the power button 31. Subsequently, the user who wants to see the VOD presses the VOD button 33 in item number 2. The CPU 7 in FIG. 1 understands that the VOD button 33 has been pressed, and activates the HTML browser 8 through the remote control receiver 17. The HTML browser 8 receives an operation screen including a list of contents from the VOD server 22 in FIG. 3 and displays it on the display panel 2.

  In item number 3 in FIG. 5, the user selects and determines a title from the content list using the remote controller. In item number 4 of FIG. 5, the VOD server 22 of FIG. 3 performs charging and confirmation of the right to play, and if there is no problem, sends the moving image content to the television 1 with a videophone function via the network 16. In item No. 5 in FIG. 5, in order to perform the reproduction operation, the CPU 7 in FIG. 1 performs an input switching operation of the decoder 5 to start the operation of the decoder 5. The VOD content data sent through the NW I / F 16 is decompressed (decoded) by the decoder 5, displayed on the display panel 2, and reproduced.

  Thereafter, the user can use the remote controller 11 to operate the VOD content being played back. However, when the playback ends, the user presses the stop button 35 as indicated by item number 6 in FIG. The CPU 7 recognizes the user's intention to stop through the remote control reception unit, and performs the stop operation of the decoder 5 and the stop operation of the HTML browser 8. When the decoder 5 is stopped, the display of the VOD content displayed on the display panel 2 is also ended, and the reproduction of item number 7 in FIG. 5 is ended.

Next, the processing procedure of the videophone processing will be described using the telephone processing column of FIG.
In item number 1 in FIG. 5, the user presses the power button 31 of the remote controller 11. When the power is already on, it is not necessary to press the power button 31. Subsequently, in item No. 2, the user informs the user that he / she wants to use the videophone by pressing the videophone button 34. The CPU 7 in FIG. 1 activates the HTML browser 8 when confirming this via the remote control receiver 17.

  Here, for the telephone function, it connects to the videophone server of FIG. 3 and receives operation screen information, and the HTML browser 8 displays the operation screen on the display panel 2. In item number 3 in FIG. 5, the user operates the remote controller 11 to select and determine a call destination. Thereafter, in item number 4 in FIG. 5, the HTML browser 8 obtains the screen information from the videophone server in FIG. 3 and displays it in order to display the calling screen. Further, the CPU 7 operates to operate the camera 13, the microphone 14, and the encoder 15 to prepare for sending this video to the other party.

  Subsequently, in item number 5 in FIG. 5, the CPU 7 switches the input of the decoder 5 and starts the operation for the call processing. The other party's video and audio sent from the network 16 are sent to the decoder 5 through the NW I / F 10, and the decoder 5 decompresses or decodes the compressed video data and displays it on the display panel 2. .

  The other party's videophone function-equipped TV 23 in FIG. 3 performs the same operation, and when the decoder 5 starts to operate in item 5 in FIG. Information obtained by compressing the moving image of the microphone 14 with the encoder 15 is received by the other party, decoded, and displayed. In FIG. 5 item 6, the user who wishes to end the call presses the stop button 35 on the remote control.

  The CPU 7 interpreting this stops the decoder 5, stops the HTML browser 8, and stops the camera 13, microphone 14, and encoder 15. When the encoder 15 stops, the compressed data does not reach, so the counterpart decoder 5 also stops. As a result, the call is terminated at item number 7 in FIG.

  Comparing the processing procedure in the telephone with the VOD described with reference to FIG. 5, the input of the decoder is switched because the video source is different, but it can be understood that the stop process can be performed by the stop button of the remote controller. .

  For example, a common decoder is used to decode the compressed video of broadcast waves, VOD, and videophones. If so, three types of decoders are required. It can be developed and manufactured at low cost and provided to users. In addition, it is considered that the user can easily understand the stop process because it is only necessary to press the stop button.

  FIG. 6 is a table explaining the difference in processing when a videophone call arrives for each television operating state. Here, as an operation state, a power-off state, a television viewing state, a VOD viewing state, and other states are separately described.

  First, in a power-off state, the incoming call detection means 9 in FIG. 1 detects an incoming call and notifies the CPU 7. If the CPU 7 activates the HTML browser 8 and displays the incoming call screen and then the user can make an incoming call by remote control operation, it is the same as in item 4 in the telephone processing described in FIG. Then, the operation of the camera 13, the microphone 14, and the encoder 15 is started.

After that, the process proceeds according to the item numbers 5, 6, and 7 and the user operation, and the call ends. When the telephone processing is completed, the display returns to the power-off column in FIG. 6 and the television viewing screen is displayed.
As a result of the above operation, the television 1 with a videophone function can receive an incoming videophone call even when the power is off.

  Subsequently, in the case where an incoming call is received while watching the television, the CPU 7 receives notification of detection of the incoming call from the incoming call detection means 9 and if it is determined that the television is being watched, the CPU 7 The operation is performed so as to save the output in the storage 12. That is, recording is automatically started. Note that, after the start of recording, telephone processing including display of a calling screen is started for the first time. Thereafter, when the telephone processing is finished, the reproduction of the currently viewed TV program that has started automatic recording is started.

  As a result of the above operation, even if a videophone call arrives while watching TV, the TV 1 with the videophone function automatically starts recording and confirms that it has started, so the incoming call processing is started for the first time. Never miss a program you were watching.

In the incoming call process during VOD viewing in FIG. 6, when the CPU 7 detects an incoming call, when the VOD is being viewed, the CPU 7 requests the VOD server 22 in FIG. 3 to perform a pause (pause) process. After that, when the telephone processing is finished, the CPU 7 requests a bose (temporary stop) release process, and operates so that the VOD viewing content is reproduced as it is.
As a result of the above operation, even if there is an incoming call while viewing the VOD, the operation is automatically paused, and when the call ends, the original operation can be resumed. Therefore, there is no problem even if VOD viewing is temporarily interrupted.

  The columns in other cases in the table of FIG. 6 mean that the processing is other than power-off, TV viewing or VOD viewing. Since the incoming call is basically an interruption to work or operation, the CPU 7 in FIG. 1 saves the current state, starts processing the phone, and when it is finished, saves the state. Is taken out and restored.

  For example, it is possible to receive a call while watching a program guide. Even in such a case, the CPU 7 immediately saves the current state, starts the telephone process, and then retrieves the saved state. It is possible to return to the state.

Subsequently, a method for changing the camera orientation will be described in order to adjust the position of the subject on the TV screen when the above-described videophone function is used in this embodiment.
First, with reference to FIG. 7, the details of the camera 13 built in the television 1 with a videophone function will be described.
FIG. 7 shows a cross section of the camera portion built in the TV 1 with a videophone function.

  The shooting direction of the camera 13 varies depending on the camera direction 13b. Normally, the camera orientation 13b is oriented in the vertical direction of the television screen. For example, the camera 13 has a round shape like a ball so that it can be changed vertically and horizontally. Further, in order to be able to change the camera direction 13b up and down and left and right with the user's hand, for example, the camera lens unit 13a protrudes from the television housing and can be picked up by hand. The user can change the desired camera orientation 13 a by picking the camera lens unit 13 b and moving the camera 13.

Next, how to change the camera orientation 13b will be described while confirming the reflection on the screen with reference to FIGS.
When the TV 1 with the video phone function is turned on, regardless of whether the video phone function is used or not, when the camera orientation setting button 36 of the remote control 11 is pressed, the TV with the video phone function is shown in FIG. On the display panel 2 of 1, the subject moving position screen is displayed.

  As a detailed operation, when the user presses the camera direction button 36 of the remote controller 11, the CPU 7 controls to output the video captured by the camera 13 to the display panel 2 in response to the button press received by the remote control receiver 17. Do. Thus, for example, when the user becomes a subject, the user can confirm his / her reflection position on the display panel 2 screen.

FIG. 8 shows a state before the camera orientation adjustment on the subject projection position adjustment screen.
For example, when the subject projection position is too far to the right on the subject projection position adjustment screen 2a toward the TV, the user picks the camera lens portion 13a of the camera 13 and confirms the screen until the desired projection position is reached. The camera direction 13b is adjusted little by little to the left.

FIG. 9 shows a state after the camera orientation adjustment on the subject projection position adjustment screen.
As a result of adjusting the camera orientation 13b, the camera orientation 13b can be set to face the user even if the subject (user) is not actually in front of the television 1, so that the subject appears in the middle on the subject projection position adjustment screen 2a. Became.

  When the adjustment is completed, the camera direction setting button 36 of the remote controller 11 is pressed again. As a result, the display panel 2 screen returns to the screen before the first camera orientation setting button 36 is pressed.

  FIG. 10 shows how the videophone function is used. When a video is output from the camera 13 that shoots the user (subject) to the display panel 2, it is displayed as a PIP (Picture in Picture) 2 c, so that the user can receive the image from the other party and watch the video at the same time. Can be confirmed.

  In this case, since the user can confirm his / her own reflection position on the PIP2c screen, if the user determines that the moving position is not correct, he / she picks up the camera lens unit 13a of the camera 13 and confirms the PIP2c screen. The camera direction 13b is adjusted little by little to the left until the projected position.

  As described above, when the video phone function is used, the user can freely determine the location of the camera 13 by incorporating the camera 13 in the TV 1 with the video phone function so that the shooting direction of the camera 13 can be changed. It is possible to have a conversation at a desired reflection position.

Next, a second embodiment of the present invention will be described.
In this embodiment, in order to further improve the convenience for the user, the subject image position adjustment described in the first embodiment on the TV 1 with a videophone function using the remote controller 11 will be described.

  FIG. 11 is a block diagram in which the camera orientation control means 18 in the present embodiment is added to the block diagram of the television 1 with the videophone function in the first embodiment. When the user presses the camera orientation setting button 36 on the remote controller 11, a subject image position adjustment screen 2a is displayed as shown in FIG.

  In this state, when the up, down, left, or right button of the cross key 37 of the remote controller 11 is pressed, the remote controller 11 transmits a camera orientation change command corresponding to the amount or time of pressing the button. The remote control receiving unit 17 receives a camera orientation change command corresponding to the pressing operation of the remote controller 11 and sends it to the camera orientation control means 18. In response to the camera direction change command, the camera direction control means 18 generates movement information for a camera direction left / right direction adjustment unit 18b or a camera direction vertical direction adjustment unit 18a, which will be described later, and uses this movement information as the camera direction left / right direction adjustment unit 18b. Alternatively, the image is sent to the camera-facing vertical direction adjustment unit 18a. The camera direction horizontal direction adjustment unit 18b or the camera direction vertical direction adjustment unit 18a changes the camera direction 13b according to the movement information.

FIG. 12 shows an example of a diagram showing a mechanism around the camera 13 in order to adjust and adjust the camera orientation 13b using the camera orientation control means 18 in this embodiment.
Similarly to the first embodiment, the shape of the camera 13 is a round shape such as a ball so that the camera direction 13b can be changed vertically and horizontally. The camera orientation control means 18 includes a camera orientation 13b vertical adjustment unit 18a and a camera orientation horizontal adjustment unit 18b in order to perform control to change the camera orientation 13b up and down and left and right. Hereinafter, how to change the camera orientation 13b using the camera orientation changing means 18 will be described in detail.

  When the user presses the right button or the left button of the cross key 37, the remote controller 11 transmits a camera orientation change command corresponding to the button pressing amount or pressing time. The camera direction control means 18 generates movement information in the left-right direction in response to the camera direction change command and sends it to the camera direction left-right direction adjustment unit 18b. The camera direction left-right direction adjustment unit 18b changes the camera direction 13b to the right or left according to the movement information. The camera direction left and right direction adjustment unit 18b includes a gear that is rotated by a motor about the vertical axis, for example, and rotating the gear rotates the main body of the camera 13 to change the camera direction 13b to the left and right. .

  On the other hand, when the user presses the upper button or the lower button of the cross key 37, the remote controller 11 transmits a camera orientation change command corresponding to the amount or time of pressing the button. The camera direction control means 18 generates movement information in the vertical direction in response to the camera direction change command and sends it to the camera direction vertical direction adjustment unit 18a. The camera orientation up / down adjustment unit 18a changes the camera orientation 13b up or down according to the movement information. The camera up / down direction adjustment unit 18a includes, for example, a gear that is rotated by a motor around the horizontal axis. By rotating the gear, the main body of the camera 13 rotates to change the camera direction 13b up and down. .

  In addition, although it was set as operation by the up / down / left / right button 37 of the remote controller, the same processing as described above can be performed by using the up / down / left / right button on the television main body. At that time, a camera direction change command corresponding to the amount or time of pressing the button is sent from the CPU 7 to the camera direction control means 18. Instead of providing independent buttons for up / down / left / right, it is also possible to select up / down and left / right movement from a TV menu, etc., and operate within that.

  As described above, when it is determined on the subject projection position adjustment screen 2 a shown in FIG. 8 that the subject projection position is not correct, the user operates the up / down / left / right buttons of the cross key 37 of the remote controller 11 to incorporate the subject in the television 1. The camera orientation 13b can be changed, and the subject projection position as desired by the user can be adjusted as shown in FIG.

  As in the first embodiment, when it is desired to end the adjustment of the subject image position, the camera orientation setting button 36 of the remote controller 11 is pressed again. Thereby, the screen before the first pressing of the camera orientation setting button 36 is displayed on the display panel 2 screen.

  The state of camera orientation adjustment during the use of the videophone function will be described with reference to FIG. When using the videophone function, for example, an image of the user (subject) is displayed as a PIP2c screen. At this time, when the user presses the camera orientation setting button 36 of the remote controller 11, in order to inform the user that the camera orientation 13b is currently adjustable, the frame of the PIP2c screen area is thickened as shown in FIG. Displays the “Orientation” message.

  At this time, the camera orientation can be adjusted by pressing the up / down or left / right button of the cross-37 of the remote controller 11. When the adjustment of the camera orientation 13b is completed, the camera orientation setting button 36 of the remote controller 11 is pressed again. As a result, the frame of the PIP2c screen is restored and the “orientation” message is deleted.

  Thus, by providing the camera direction control means 18 in the TV 1 with the videophone function, the user can adjust the subject projection position on the screen by using the remote controller 11 of the TV1 with the videophone function.

Subsequently, a third embodiment of the present invention will be described with reference to FIG.
In this embodiment, for example, it is impossible to mount the mechanical camera orientation adjustment mechanism shown in FIG. 12 in order to reduce the thickness of the TV body or reduce the cost, and the subject when the shooting direction of the camera 13 is fixed. A reflection position adjusting method will be described.

  FIG. 13 is a block diagram in which an image processing means 19 is added to the block diagram of the television 1 with the videophone function of FIG. 1 of the first embodiment. As in the second embodiment, when the user presses the camera orientation setting button 36 of the remote controller 11 and operates the cross key 37 of the remote controller 11, the remote controller receiving unit 17 receives the operation command. The CPU 7 interprets the command as movement information and sends it to the image processing means 19. Next, a method for adjusting the subject image position using the image processing means 19 will be described.

FIG. 14 shows an example of a television cross-sectional view of a built-in camera portion in which the shooting direction is fixed.
Since the camera 13 main body is fixed, the camera orientation 13b cannot be changed. In this case, the camera direction 13b is, for example, the vertical direction of the television screen. In order to adjust the subject projection position, the resolution of the sensor imaged by the camera 13 is made larger than the resolution of the video used for the videophone function.

  For example, when the resolution of the video used for the videophone function is 1280 × 720 pixels, the resolution of the video shot by the sensor of the camera 13 is 1600 × 1400 pixels. In addition, in order for the camera 13 to widen the shooting range, a wide-angle lens is used for the camera lens unit 13a.

FIG. 15 shows an example of the processing procedure of the image processing means 19 in the subject projection position adjusting method of this embodiment.
First, a high resolution image taken by the camera 13 is input to the image processing means 19 (step S19a). Next, correction is performed to reduce distortion caused by shooting using a wide-angle lens (step S19b). Thereafter, it is determined whether or not the output image range is moved by the operation of the cross key 37 of the remote controller 11 interpreted by the CPU 7 (step 19c). If it is determined that there is movement, RAM (Random Access) is used using the movement information. The position information 19a of the output area stored in (Memory) or the like is updated (step 19d).

  If it is determined that there is no movement, the process proceeds to the next step. Next, the position information 19 is used to cut out the original image at the video resolution used in the videophone function (step S19e). Finally, the cut image is sent to the encoder 15 and the display panel 2 (step S19f).

FIG. 16 is a diagram illustrating a state in which it is determined that the subject reflection position is not correct in the present embodiment.
In the original high-resolution video 2d photographed by the camera 13, the area output on the display panel 2 screen of the TV 1 with the videophone function is the videophone operating resolution area 2e before adjustment, and the subject is directed toward the TV. Too close to the.

FIG. 17 is a diagram illustrating a state in which the user performs the procedure of FIG. 15 several times using the left button of the cross key 37 of the remote controller 11 in the state of FIG. Although the operation using the up / down / left / right button 37 of the remote controller will be described, the same processing as described above can be performed using the up / down / left / right button on the television main body. Without moving up, down, left and right independent buttons, it is also possible to select up and down and left and right movements from a TV menu, etc., and operate within them.
Since the adjusted TV screen output area 2e is centered on the subject, the image processed by the display panel 2 or the encoder 16 is an image centered on the subject.

  From the above, when it is determined that the subject projection position is not correct for the user as shown in FIG. 8, the user operates the remote controller 11 to adjust the image area to be displayed from the original image captured by the camera 13. As shown in FIG. 9, even if the user (subject) is not directly in front of the TV 1, the image area is selected from the original high-resolution image taken with the subject at the center, so that the TV with a videophone function can be used. For example, it is possible to realize that a subject appears in the middle on the screen of one display panel 2.

  When the video call function is used and the camera video of the user (subject) is displayed as the PIP2c screen, the camera orientation adjustment will be described with reference to FIG. When the user presses the camera orientation setting button 36 on the remote controller 11, the frame of the PIP2c screen area becomes thick as shown in FIG. 13, and for example, an “orientation adjustment” message is displayed in the PIP2c area. At this time, the camera orientation can be adjusted by using the up / down and left / right buttons of the cross-37 of the remote controller 11. When the adjustment is completed, when the camera orientation setting button 36 of the remote controller 11 is pressed again, the frame of the PIP2c screen is restored, and the “orientation” message disappears.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
