It is a functional block diagram which shows the structure of the television of Embodiment 2 which concerns on this invention.

  Hereinafter, a television will be described as an example of a display device remotely operated by a remote controller.

  As shown in FIG. 1, the television of this embodiment includes a television body 10 and a remote controller 20 that remotely controls the television body 10.

  The remote control 20 includes a remote control operation unit 201, a timer unit 202, a photographing signal generation unit 203, and a remote control transmission unit 204.

  The remote control operation unit 201 includes a key (not shown), and when the user operates the key, a remote control signal corresponding to the operated key (a control signal corresponding to a control command in the TV main body 10) is transmitted to the remote control transmission unit 204. Output to. Remote control operation unit 201 outputs a signal indicating that a remote control signal has been output to timer unit 202.

  When the timer unit 202 acquires a signal indicating that a remote control signal is output from the remote control operation unit 201, the timer unit 202 activates the initialized timer. The timer unit 202 outputs a timer signal to the imaging signal generation unit 203 every time it is determined that a predetermined time has elapsed by the timer.

  When the shooting signal generation unit 203 acquires the timer signal, the shooting signal generation unit 203 generates a special remote control signal (hereinafter referred to as “shooting signal”) that controls the camera 111 to perform shooting under the control of the camera control unit 110. To the remote control transmission unit 204.

  When the remote control transmission unit 204 acquires a remote control signal corresponding to the key operated by the remote control operation unit 201 or a remote control signal to be photographed by the camera 111 by the photographing signal generation unit 203, the remote control transmission unit 204 outputs the remote control signal by radio such as infrared rays.

  The TV main unit 10 includes a tuner unit 102, an audio / video processing unit 103, an audio output unit 104, a display control unit 105, a display unit 106, a main body operation unit 107, a remote control reception unit 108, a remote control signal processing unit 109, and a camera control unit 110. A camera 111, a captured image reproduction processing unit 112, a captured image storage unit 113, and a CPU (Central Processing Unit) 101 that controls these units are provided.

  The remote control signal output from the remote controller 20 is received by the remote control receiver 108. The remote control signal processing unit 109 checks the remote control reception unit 108 to determine whether a valid remote control signal has been received. Whether or not it is a valid remote control signal may be determined, for example, based on whether or not it matches a remote control code stored in advance in the remote control signal processing unit 109. If the remote control signal acquired by the remote control signal processing unit 109 is a remote control signal for controlling another electronic device or a weak remote control signal that cannot be demodulated because the remote control 20 and the TV main body 10 are separated, they are stored in advance. The remote control code does not match and is determined to be an invalid remote control signal. When the remote control signal processing unit 109 determines that the acquired remote control signal is a valid remote control signal, the remote control signal processing unit 109 causes each unit to perform processing corresponding to the remote control signal via the CPU 101.

  For example, if the remote control signal determined to be valid by the remote control signal processing unit 109 indicates a television broadcast channel number, the tuner unit 102 connects an unillustrated antenna or cable under the control of the CPU 101. The broadcast signal is acquired, the channel corresponding to the channel number is selected, the demodulation / error correction is performed, and the video / audio signal is output to the video / audio processing unit 103.

  When the video / audio processing unit 103 acquires the video / audio signal from the tuner unit 102, the video / audio processing unit 103 separates the video / audio signal into a video signal and an audio signal. The video / audio processing unit 103 performs sound quality adjustment, volume adjustment, and the like on the audio signal, and outputs audio from the audio output unit 104 such as a speaker. In addition, the video / audio processing unit 103 performs predetermined image processing, scaling, and the like on the video signal, and displays the video on the display unit 106 via the display control unit 105.

  By the way, in the remote controller 20, when the remote control operation unit 201 is operated, a shooting signal is transmitted as a remote control signal every predetermined time regardless of the command content of the remote control signal from the remote control operation unit 201. Therefore, when the remote control signal processing unit 109 acquires a remote control signal corresponding to a key operation of the remote control operation unit 201 via the remote control reception unit 108, the remote control signal processing unit 109 acquires a remote control signal that is a shooting signal multiple times at intervals. become.

  When the remote control signal processing unit 109 determines that the remote control signal that is a shooting signal is valid, the camera control unit 110 causes the camera 111 to perform shooting through the CPU 101.

  The camera control unit 110 controls the camera 111 to shoot the viewing space. When the viewing space is photographed by the camera 111, the camera control unit 110 acquires a photographed image by the camera 111 and stores it in the photographed image storage unit 113. At this time, the photographed image may be stored in association with the photographing time or remote control signal information by the remote control operation unit 201 immediately before the remote control signal processing unit 109 acquires the photographing signal. The captured image may be stored in association with the content information displayed on the display unit 106 during shooting. For example, the camera control unit 110 causes the camera 111 to shoot and simultaneously causes the display control unit 105 to capture the screen of the display unit 106 and associates the image captured by the camera 111 with the image captured by the display control unit 105. May be stored. A remote control signal that is a photographic signal is transmitted a predetermined number of times through a predetermined interval to one remote control signal output from the remote control operation unit 201. That is, the camera control unit 110 causes the camera 111 to perform interval shooting when an arbitrary remote control operation is performed on the television main body 10 by the user.

  The captured image storage unit 113 stores a captured image captured by the camera 111. The photographed image stored in the photographed image storage unit 113 is a series of photographed images each time a series of new photographing is performed by the camera 111 by a photographing signal transmitted following a remote control signal from the remote control operation unit 201. It may be updated. This is because the user's behavior after the remote controller 20 is last operated may be recorded. As a result, only a series of captured images corresponding to the last remote control operation is stored, and the main body operation unit 107 is operated to display the stored captured images on the display unit 106 via the display control unit 105. .

  The main body operation unit 107 is a dedicated operation unit provided to output an operation signal for displaying a stored captured image. The main body operation unit 107 is operated by the user when the user forgets the location of the remote controller 20, for example. When operated by the user, the main body operation unit 107 outputs an operation signal to the captured image reproduction processing unit 112.

  When the captured image reproduction processing unit 112 acquires the operation signal, the captured image reproduction processing unit 112 reads the captured image stored in the captured image storage unit 113 and causes the display unit 106 to display the captured image. FIG. 2 is an image diagram illustrating a state in which a captured image obtained by interval shooting is displayed on the display unit 106 via the display control unit 105. In FIG. 2, the state after the user's remote control operation is shown in time series in the order of (a) to (d). In FIG. 2 (a), a picture immediately after the user operates the remote control 20 is taken. In FIG. 2 (b), a picture of the user standing up with the remote controller 20 is taken. In FIG. 2 (c), the user attempts to open the door that leads to the next room with the remote controller 20. In FIG. 2D, the state where the door of the adjacent room is opened and the user disappears is photographed. Note that the shooting time of each shot image, information related to the remote control signal from the remote control operation unit 201 (for example, what operation was performed by the remote control signal), content information, and the like may be displayed together with the shot image.

  Thereby, the user can confirm what action was taken after the last operation of the remote controller 20 based on a series of captured images displayed on the display unit 106, and the place where the remote controller 20 was placed. You can get hints on clues. For example, in the case shown in FIG. 2, it is understood that the user may have moved to the next room such as the kitchen after operating the remote controller 20 and misplaced the remote controller 20. You can go looking for the remote control 20 in the kitchen without looking for a room.

  Specifically, the flow of television processing when the remote controller 20 is operated and the flow of television processing when the main body operation unit 107 is operated will be described.

  First, with reference to FIG. 3, the flow of processing of the remote controller 20 when the remote controller operation unit 201 is operated will be described.

  In step A10, the remote control operation unit 201 determines whether a key has been operated by the user. In the case of No in step A10, the remote control operation unit 201 returns the process to step A10. On the other hand, when it is determined that the key has been operated (Yes in step A10), the remote control operation unit 201 proceeds to step A11, outputs a remote control signal corresponding to the operated key, and transmits it via the remote control transmission unit 204.

  Next, in step A12, the timer unit 202 obtains a signal indicating that a remote control signal has been output from the remote control operation unit 201, and activates the timer. In step A13, the remote control operation unit 201 determines whether or not the key has been operated by the user. If yes in step A13, the process returns to step A11, and if no in step A13, the process proceeds to step A14.

  In step A14, the timer unit 202 determines whether or not a predetermined time has elapsed. If No in step A14, the timer unit 202 returns the process to step A13. On the other hand, in the case of Yes in step A14, the process proceeds to step A15, where the shooting signal generation unit 203 acquires a timer signal indicating that a predetermined time has elapsed from the timer unit 202, generates a shooting signal, and sets the remote control transmission unit 204 to Send through. In step A <b> 16, the photographing signal generation unit 203 increments a counter indicating the number of times the photographing signal is transmitted. In step A17, the imaging signal generation unit 203 determines whether or not the counter value has reached a predetermined value. In the case of No in step A17, the process returns to step A12, and the processing from step A12 to step A17 is repeated until the photographing signal corresponding to the remote control signal from the remote control operation unit 201 is transmitted a predetermined number of times. On the other hand, in the case of Yes in step A17, that is, when the photographing signal generation unit 203 determines that the value of the counter has reached a predetermined value, this processing ends. In the above processing, it is assumed that the timer and the counter are initialized in advance. Further, it is assumed that the predetermined number of times in Step A17 is set in advance to a factory setting value or a setting value set by the user.

  Next, with reference to FIG. 4, the process flow of the television main body 10 that has received the remote control signal will be described.

  In step A20, the remote control signal processing unit 109 checks whether the remote control receiving unit 108 has received a remote control signal. In the case of No in step A20, the remote control signal processing unit 109 returns the process to step A20. On the other hand, if Yes in step A20, the process proceeds to step A21, and the remote control signal processing unit 109 determines whether or not the received remote control signal is a valid remote control signal. For example, the remote control signal processing unit 109 may determine that the remote control signal is an effective remote control signal if the remote control code stored in advance matches the remote control signal. In the case of No in step A21, the remote control signal processing unit 109 ends this process. On the other hand, if Yes in step A21, in step A22, the remote control signal processing unit 109 determines whether the remote control signal is a special remote control signal, that is, a shooting signal.

  In the case of No in step A22, the remote control signal processing unit 109 proceeds to step A23, causes each unit to perform processing according to the remote control signal, and ends this processing. On the other hand, if Yes in step A24, that is, if the remote control signal processing unit 109 determines that the signal is a special remote control signal, the process proceeds to step A24. In step A <b> 24, the camera control unit 110 causes the camera 111 to perform shooting, stores the captured image in the captured image storage unit 113, and ends the present process.

  As described above, each time the remote controller 20 is operated by the user, the remote controller 20 transmits a remote control signal corresponding to the operated key, and when a predetermined time elapses after the remote controller 20 is operated, the camera control unit 110. A special remote control signal that causes the camera 111 to take a picture is transmitted a predetermined number of times via an interval. The TV main body 10 performs processing corresponding to the key operated by the remote controller 20 according to the received remote control signal, and records and records the state of the user after the remote control operation a predetermined number of times. As a result, when a predetermined time elapses after the user operates the remote controller 20, shooting is performed at predetermined intervals, and it is possible to avoid unnecessary shooting while the user frequently operates the remote controller 20. .

  Next, with reference to FIG. 5, a processing flow of the television main body 10 when the main body operation unit 107 is operated will be described.

  In step B10, the captured image reproduction processing unit 112 determines whether or not the main body operation unit 107 has been operated by the user. If No in step B10, the process returns to step B10. On the other hand, if Yes in step B10, the process advances to step B11, and the captured image reproduction processing unit 112 acquires the captured image stored in the captured image storage unit 113. In step B12, the captured image reproduction processing unit 112 causes the display control unit 105 to display the acquired captured image on the display unit 106, and ends this process.

  As a result, when the user does not know where the remote controller 20 is, the user places the remote controller 20 by operating the main body operation unit 107 and using the image after the user's remote control operation displayed on the display unit 106. Get location tips.

  In the above-described embodiment, the configuration in which the timer unit 202 and the photographing signal generation unit 203 are provided in the remote controller 20 has been described, but may be provided in the television main body 10. In the television shown in FIG. 6, the timer unit 202 and the shooting signal generation unit 203 provided in the remote control 20 shown in FIG. 1 are not connected to the remote control 21 shown in FIG. The unit 123 is provided. In FIG. 6, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  When a user operates a key (not shown), remote control operation unit 201 transmits a remote control signal corresponding to the operated key via remote control transmission unit 204.

  When receiving the remote control signal, the remote control receiving unit 108 outputs the remote control signal to the remote control signal processing unit 109. When the remote control signal processing unit 109 acquires the remote control signal from the remote control receiving unit 108, the remote control signal processing unit 109 determines whether the remote control signal is a valid one. When the remote control signal processing unit 109 determines that the remote control signal is an effective remote control signal, it causes each unit to perform processing corresponding to the remote control signal via the CPU 101. At the same time, the remote control signal processing unit 109 operates the timer by the timer unit 122.

  When the timer unit 122 determines that the predetermined time has elapsed by the timer, the timer unit 122 causes the shooting signal generation unit 123 to generate a shooting signal (special remote control signal). The shooting signal generation unit 123 generates a shooting signal every time when the timer unit 122 determines that the predetermined time has elapsed until the predetermined number of times is reached, and outputs the shooting signal to the camera control unit 110. The camera control unit 110 causes the camera 111 to shoot the viewing space each time a shooting signal is acquired, and stores the shot image in the shot image storage unit 113.

  As described above, when the TV main body 10 acquires the remote control signal from the remote control unit 201 from the remote controller 20, the TV signal generation unit 123 generates a shooting signal every predetermined time until the predetermined number of times is reached, and the camera control unit based on the shooting signal The viewing space is photographed by the camera 111 via 110, and the photographed image is stored in the photographed image storage unit 113. As a result, when the user does not know where the remote control 20 is located, the user operates the main body operation unit 107, and the hint regarding the place where the remote control 20 is placed is displayed based on the image after the remote control operation displayed on the display unit 106. Can be obtained.

  In the above embodiment, when the main body operation unit 107 is operated, an operation signal for displaying a stored captured image is output to the captured image reproduction processing unit 112. However, other predetermined operations are performed. When performed, an operation signal may be output to the captured image reproduction processing unit 112.

  For example, when a plurality of predetermined operation units are operated at the same time with respect to the operation units provided in the television main body 10 in order to realize functions equivalent to those of the remote controller 20 instead of the dedicated main unit operation unit 107, shooting is performed. An operation signal may be output to the image reproduction processing unit 112. An operation signal may be output to the captured image reproduction processing unit 112 when a power button provided on the television main body 10 is operated, that is, when the power is turned on regardless of a remote control signal. In addition, when the user performs an operation of waving near the camera 111, that is, when the camera control unit 110 detects that the video brightness in the camera 111 has suddenly changed in a short time, the captured image is reproduced. An operation signal may be output to the processing unit 112. Further, for example, when the user operates the power button provided on the television main body 10 with the camera 111 hidden by the hand, that is, the video brightness detected by the camera control unit 110 by the camera 111 is dark. In addition, when the power button of the television main body 10 is operated, an operation signal may be output to the captured image reproduction processing unit 112.

  In addition, when the television main body 10 has a network function, the operation signal may be transmitted to the television main body 10 via the network. Further, the mobile phone may transmit a dedicated remote control signal for causing the captured image reproduction processing unit 112 to reproduce the captured image to the television body 10. The dedicated remote control signal may be distributed so as to be downloadable, for example, as an application for a mobile phone.

  In the above embodiment, the camera control unit 110 may cause the camera 111 to capture a still image or a moving image. When the camera control unit 110 causes the camera 111 to shoot with a moving image, for example, every time a shooting signal is acquired, the camera control unit 110 may shoot with a moving image for a predetermined time. In addition, the camera control unit 110 may cause the camera 111 to perform shooting by mixing still images and moving images. For example, the camera control unit 110 causes the camera 111 to take a moving image for a predetermined time immediately after the remote control 20 is operated, which is likely to be released, and then stops at a predetermined time until the predetermined number of times is reached. You may make it take a picture. In this case, it may be counted as one time from the start to the end of video shooting, and may be included in the predetermined number of times, or the video shooting may not be included in the predetermined number of times. Further, the photographing signal may be output only once without being output a plurality of times.

  The captured image reproduction processing unit 112 performs image recognition processing on the captured image read from the captured image storage unit 113, and if the same remote control image as the previously stored remote control image is present in the captured image, A photographed image processed so that the remote control image portion is conspicuous may be displayed on the display unit 106 via the display control unit 105.

  In addition, when the remote controller 20 can remotely control not only the TV main body 10 but also other electronic devices, the camera control unit 110 is for an operation target apparatus whose remote control signal from the remote controller 20 is different from that of the TV main body 10. Sometimes, the camera 111 may take a picture and information related to the operation target device and the taken image may be stored in association with each other. Specifically, the remote control signal processing unit 109 may store not only a remote control code corresponding to the television main body 10 but also a remote control code corresponding to another operation target device. The remote control signal processing unit 109 determines which operation target device the remote control signal acquired via the remote control reception unit 108 is for. When it is determined by the remote control signal processing unit 109 that the remote control signal is for a device to be operated different from the television main body 10, the camera control unit 110 captures the shooting signal by the shooting signal generation unit 123 every predetermined time by the timer unit 122. To cause the camera 111 to take a photograph and store the photographed image in association with information on the operation target device corresponding to the remote control signal. For example, when the main body operation unit 107 is operated, the display control unit 105 displays information related to the operation target device corresponding to the remote control signal together with the captured image. According to this, even when an operation target device different from the television main body 10 is operated by the remote controller 20, the state of the viewing space after the remote controller 20 is operated can be recorded.

  Note that the camera control unit 110 may record the state of the viewing space after each operation of the plurality of remote controllers 20. For example, when there is a remote control 20 of the TV main body 10 and a remote control different from the remote control 20 for the AV device, the camera control unit 110 operates the remote control 20 of the TV main body 10 when the remote control 20 is operated. The state of the subsequent viewing space is recorded in association with the remote control 20 of the TV main body 10, and when the remote control of the AV device is operated, the state of the viewing space after the operation is recorded in association with the remote control of the AV device. At this time, the captured image storage unit 113 may be provided for each of the plurality of remote controllers, or the storage area may be provided separately for each of the plurality of remote controllers. According to this, even when the remote control 20 of the TV main body 10 is operated to switch to the AV device and the playback operation is performed using the remote control of the AV device, the remote control 20 of the TV main body 10 and the remote control of the AV device For each of the above, the recorded state of the viewing space after the operation can be reproduced, and it can be searched for with hints.

  Further, the remote controller 20 may be provided with an acceleration sensor. For example, when the acceleration sensor detects that the remote controller 20 has been moved by the user, the remote controller 20 causes the shooting signal generation unit 203 to generate a shooting signal every predetermined time by the timer unit 202 and the remote control transmission unit 204 The photographing signal may be transmitted through the terminal. In this case, not only when the user operates the remote control unit 201, but when the remote controller 20 is touched, a shooting signal is transmitted and shooting is performed by the camera 111. Therefore, when the remote controller 20 is finally moved. Can be taken. When both the operation of the key by the remote control operation unit 201 and the movement of the remote control 20 by the acceleration sensor are detected, a shooting signal may be generated by either one.

  The remote controller 20 may transmit a remote control signal indicating that the remote controller 20 has been moved to the television body 10 when the acceleration sensor detects that the remote controller 20 has been moved by the user. In this case, when the TV main body 10 acquires a remote control signal indicating that the remote control 20 has been moved, the shooting signal generation unit 123 generates a shooting signal every predetermined time by the timer unit 122, and the camera control unit 110 causes the camera to operate. 111 may be used for shooting. Here, it is included in the meaning of operating the remote controller 20 including that the user touches the remote controller 20.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention. Note that, in the above-described embodiment, the same reference numerals are given to configurations showing similar functions.
