  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 is a conceptual diagram showing an example of a video output system 3 in the present embodiment. FIG. 1 shows a DTV 1, shutter glasses 2, and a video output system 3.

  The DTV 1 is, for example, a digital television and is an example of an electronic device in the present embodiment. In the present embodiment, the DTV 1 is shown as an example of an electronic device. However, the present invention is not limited to this example. Various devices such as a personal computer are considered as examples of electronic devices.

  For example, the DTV 1 can decode a broadcast signal received by a broadcast wave or the like and output the decoded signal as video or audio from the display unit 120 or the speaker 110.

  The DTV 1 has a photographing unit 160, and the photographing unit 160 can photograph an image in front of the DTV 1 as photographing means. That is, the user's face facing the DTV 1 can be photographed.

  Further, the DTV 1 can provide a stereoscopic video to a user who views the video. In the present embodiment, description will be given by taking as an example the provision of stereoscopic video to the user using shutter glasses. However, the present invention is not limited to this, and a stereoscopic image may be provided to the user using, for example, polarizing filter glasses. The DTV 1 can provide a stereoscopic image to a user wearing the shutter glasses 2 by alternately displaying a left-eye image and a right-eye image having parallax with each other (frame sequential method).

  The shutter glasses 2 are provided with liquid crystal shutters that can be shielded by the left-eye lens and the right-eye lens, respectively, and these lenses and the shutter are collectively referred to as a lens unit. The shutter glasses 2 provide stereoscopic images to the user by opening and closing the shutters of the left and right lens units at different timings based on the shutter opening / closing signals received from the DTV 1. For example, when an image for the left eye is displayed on the DTV 1, the shutter glasses 2 closes the shutter of the right eye lens unit (blocked state) based on an open / close signal from the DTV 1 and opens the shutter of the lens unit for the left eye. In the open state (transparent state), the left eye image is shown only to the user's left eye. When the right-eye image is displayed, the shutter of the left-eye lens unit is closed and the shutter of the right-eye lens unit is opened, so that the right-eye image is shown only to the user's right eye. By this operation, the user can grasp the image being viewed as a three-dimensional image. Further, the shutter glasses 2 can detect the user's wearing state of the shutter glasses 2 and can send a wearing state signal indicating the wearing state information to the DTV 1 in response to a request from the DTV 1. .

  Explaining in detail the above-mentioned principle of stereoscopic vision, human beings usually see an object with the left eye and the right eye with different positions, and parallax exists in the images seen with the left eye and the right eye. To do. By synthesizing the image seen with the left eye and the image seen with the right eye in the brain where the parallax exists, a human can recognize the object being seen as a solid. Therefore, the left eye image and the right eye image having parallax can be viewed by the respective eyes, thereby allowing the user to perceive the video as a three-dimensional image. Using this principle, as described above, the shutter glasses 2 provide the user with the video of the DTV 1 as a stereoscopic video.

  The video output system 3 includes a DTV 1 and shutter glasses 2. As described above, the user can recognize this video as a stereoscopic video by wearing the shutter glasses 2 and watching the video displayed on the DTV 1.

  Next, the internal structure of the DTV 1 and the shutter glasses 2 will be described in detail.

  FIG. 2 is a block diagram showing an example of the internal structure of the DTV 1 and the shutter glasses 2 in the present embodiment.

  First, the internal structure of the DTV 1 will be described.

  The DTV 1 includes a control unit 156 that controls the operation of each unit of the apparatus. The control unit 156 includes a CPU (Central Processing Unit) and the like. The control unit 156 is a system stored in advance in a ROM (Read Only Memory) 157 according to an operation signal input from the operation unit 116 or an operation signal transmitted from the remote controller 117 and received via the light receiving unit 118. A control program and various processing programs are started. The control unit 156 controls the operation of each unit of the apparatus using a RAM (Random Access Memory) 158 as a work memory according to the activated program. Further, the control unit 156 has a processing unit for executing various functions. This processing unit will be described later with reference to FIG.

  The input terminal 144 supplies the satellite digital television broadcast signal received by the BS / CS digital broadcast reception antenna 143 to the satellite digital broadcast tuner 145. The tuner 145 tunes the received digital broadcast signal and transmits the tuned digital broadcast signal to a PSK (Phase Shift Keying) demodulator 146. The PSK demodulator 146 demodulates a TS (Transport Stream) and supplies the demodulated TS to the TS decoder 147a. The TS decoder 147a includes the TS as a digital video signal, a digital audio signal, and a data signal. After decoding into a digital signal, it is output to the signal processing unit 100. Here, the digital video signal is a digital signal related to video that the DTV 1 can output, and the audio signal is a digital signal related to audio that the DTV 1 can output. The data signal is a digital signal related to information related to a broadcast program of broadcast waves including, for example, program related information that is information used when the DTV 1 generates an EPG (Electronic Program Guide) that is an electronic program guide. The data signal also includes a flag indicating whether the received video is a stereoscopic video.

  The input terminal 149 supplies a terrestrial digital television broadcast signal received by the terrestrial digital broadcast receiving antenna 148 to the terrestrial digital broadcast tuner 150. The tuner 150 tunes the received digital broadcast signal, and transmits the tuned digital broadcast signal to each OFDM (Orthogonal Frequency Division Multiplexing) demodulator 151. The OFDM demodulator 151 demodulates the TS and supplies the demodulated TS to each TS decoder 147b. The TS decoder 147b decodes the TS into a digital video signal, an audio signal, and the like, and then the signal processing unit 100. To output this. As an example, the DTV 1 can also watch CATV by connecting a CATV (Common Antenna Television) tuner to the input terminal 149 to which the antenna 148 is connected.

  The signal processing unit 100 performs appropriate signal processing on the digital signal output from the TS decoders 147a and 147b or the control unit 156. More specifically, the signal processing unit 100 separates the digital signal into a video signal, a digital audio signal, and a data signal. The separated video signal is output to the graphic processing unit 152, and the audio signal is output to the audio processing unit 153. The data signal is output to the control unit 156 and used for various processes. The signal processing unit 100 also performs predetermined digital signal processing on the input signal from the line input terminal 137.

  An OSD (On Screen Display) signal generation unit 154 generates an OSD signal for displaying a UI (user interface) screen and the like under the control of the control unit 156. The data signal separated from the digital broadcast signal in the signal processing unit 100 is converted into an OSD signal of an appropriate format by the OSD signal generation unit 154 and output to the graphic processing unit 152.

  The graphic processing unit 152 performs a decoding process on the digital video signal output from the signal processing unit 100. The decoded video signal is combined with the OSD signal output from the OSD signal generation unit 154 to be combined and output to the video processing unit 155. The graphic processing unit 152 can also selectively output the decoded video signal or OSD signal to the video processing unit 155.

  The video processing unit 155 performs image quality correction on the signal output from the graphic processing unit 152 and converts the signal into a video signal in a format that can be displayed by the display unit processing unit 155. The video signal converted by the video processing unit 155 is displayed on the display unit 120.

  The display unit 120 is configured by an LCD (Liquid Crystal Display), and displays an image using liquid crystal.

  The audio processing unit 153 converts the input audio signal into an audio signal in a format that can be reproduced by the speaker 110. The converted audio signal is output to the speaker 110 and reproduced.

  The LAN terminal 131 is connected to the control unit 156 via the LAN I / F 164. The LAN terminal 131 is used as a general LAN-compatible port using Ethernet (registered trademark). In this embodiment, a LAN cable is connected to the LAN terminal 131 so that it can communicate with the Internet 4.

  The imaging unit 160 is provided below the display unit 120 and can capture an image in front of the camera 160. The photographing unit 160 can detect the user's face from the captured video, and further, the detected user's face information is collated with the registered user's face information to register the detected user. It is possible to determine whether or not the user is a registered user. When the user's face is present (detected) in the video imaged by the imaging unit 160, that is, when the user is viewing the DTV 1, the DTV 1 executes various processes based on this. can do. Further, when the user's face matches the registered user, the user's individual function or setting can be executed. When the user's face can be detected from the captured video, the imaging unit 160 notifies the control unit 156 of information indicating that the user's face has been detected. It has a function of notifying the controller 156 of recognition information to be shown. As a face detection method here, for example, the face may be detected based on the user's face or the contour of the shoulder, or may be recognized by a different method. In addition, as a method of the face recognition technique here, for example, the shape of the user's eyes, nose, mouth, etc. may be recognized, and the user may be recognized (recognized) based on the shape. It may be recognized based on the quantity.

  A USB (Universal Serial Bus) terminal 133 is connected to the control unit 156 via the USB I / F 166. The USB terminal 133 is used as a general USB compatible port. For example, a mobile phone, a digital camera, a card reader / writer for various memory cards, an HDD, a keyboard, and the like are connected to the USB terminal 133 via a hub. The control unit 156 can perform communication (transmission / reception) of information with a device connected via the USB terminal 133.

  The HDD 170 is a magnetic storage medium built in the DTV 1 and has a function of storing various information possessed by the DTV 1. The HDD 170 can also store recorded broadcast programs and the like as videos.

  The communication unit 162 is an infrared communication module, for example, and can perform wireless communication with the shutter glasses 2 using infrared rays. The control unit 156 detects the display state of the right-eye image and the left-eye image of the stereoscopic video, and based on the display state of the stereoscopic video, the communication unit 162 sends a shutter open / close signal to the shutter glasses 2. It has the function to transmit. When the display unit 120 displays an image for the right eye, the control unit 156 opens the shutter for the right eye of the shutter glasses 2 (transmission state), closes the shutter for the left eye (shielding state), and closes the left eye. When the image for use is displayed, the communication unit 162 transmits an open / close signal so that the right-eye shutter is closed (shielded) and the left-eye shutter is opened (transmitted). Further, the communication unit 162 can receive a wearing state signal indicating information on the wearing state of the user's shutter glasses 2 transmitted from the communication unit 22 of the shutter glasses 2. This wearing state signal will be described later.

  Next, the internal structure of the shutter glasses 2 will be described.

  The control unit 21 controls the entire shutter glasses 2 and incorporates an MPU (Micro Processing Unit). The control unit 21 can transmit / receive signals to / from each connected module.

  The communication unit 22 is an infrared communication module, for example, and can perform wireless communication with the DTV 1 using infrared rays. In the present embodiment, the communication unit 162 and the communication unit 22 are infrared communication modules, and the DTV 1 and the shutter glasses 2 are illustrated as communicating with infrared rays, but are not limited thereto. For example, the communication unit 162 and the communication unit 22 can be configured by communication modules compliant with various communication standards, including wireless standards such as Bluetooth (registered trademark) and wired and wireless. The communication unit 22 has a function of receiving an opening / closing signal to the shutter glasses 2 transmitted from the communication unit 162 of the DTV 1 and a function of transmitting a wearing state signal indicating a user wearing state of the shutter glasses 2.

  The wearing detection unit 23 is a switch having a function of detecting the wearing of the user's shutter glasses 2 as a wearing detection unit. For example, in the present embodiment, it is assumed that the wearing detection unit 23 is a press switch provided on the nose pad (corresponding position) of the shutter glasses 2. When the user wears the shutter glasses 2, the wearing detection unit 23 comes into contact with the user's nose and detects a press due to this contact. In the present embodiment, the attachment detection unit 23 is illustrated as a press switch provided on the nose pad (corresponding position), but is not limited to this, and can be realized by various other configuration modes. It is. For example, the attachment detection unit 23 may be configured by a sensor such as an electrostatic touch sensor, and the portion where the attachment detection unit 23 is provided is not a portion that contacts the user's nose but a portion that contacts the ear. It may be configured. Further, the wearing detection unit 23 is not limited to being configured to detect contact with a part of the user's face, and is, for example, a switch that is pressed by the user to notify the DTV 1 of the wearing / non-wearing state. There may be. At this time, the press detection unit 23 is provided as a switch for detecting a press on a part of the frame of the shutter glasses 2, and when the user presses the switch, information on mounting / non-mounting is toggled and output (for example, It may be a power switch for switching on / off the power of the shutter glasses 2). The attachment detection unit 23 transmits the attachment state information to the control unit 21 based on the transmission request for the attachment state information from the control unit 21.

  The shutter drive unit 24 is a liquid crystal drive device that drives a shutter unit 25 made of liquid crystal. The shutter drive unit 24 has a function of driving the left and right liquid crystal shutters of the shutter unit 25 based on an open / close signal from the DTV 1 received by the communication unit 22.

  The shutter unit 25 is provided in the lens unit of the shutter glasses 2 and is driven by the shutter driving unit 24 to switch between shielding and transmission by the right-eye lens unit and the left-eye lens unit. The shutter unit 25 of the shutter glasses 2 is in a transmissive state when it does not receive an open / close signal.

  The shutter glasses 2 receive a signal transmitted from the communication unit 162 of the DTV 1 by the communication unit 22 and perform a predetermined operation based on this signal. In the present embodiment, there are two types of signals transmitted by the DTV 1, and these two types of signals are an opening / closing signal that is a signal for controlling the shielding / transmission state of the shutter glasses 2, and a user wearing the shutter glasses 2. It is a mounting state signal request that is a request signal for transmitting a mounting state signal that is a signal of state information.

  When the communication unit 22 of the shutter glasses 2 receives the open / close signal, the control unit 21 instructs the shutter drive unit 24 to drive the shutter unit 25 based on this signal. Based on this instruction, the shutter drive unit 24 switches between shielding and transmitting the shutter unit 25. When the communication unit 22 of the shutter glasses 2 receives the mounting state signal request, the control unit 21 acquires the mounting state information from the mounting detection unit 23 and transmits the mounting state information as a mounting information signal by the communication unit 22. In the present embodiment, it is assumed that the control unit 21 acquires the mounting state information from the mounting detection unit 23 when a mounting information signal request is received. However, the present invention is not limited to this. For example, when the user wears / removes the shutter glasses 2, the wearing state detection unit 23 may detect the wearing / removal and transmit the wearing state information to the control unit 21. At this time, the control unit 21 may hold the mounting state information in its own cache and transmit this information as a mounting state signal based on the mounting state signal transmission request from the DTV 1.

  With the above-described configuration, the DTV 1 can detect whether or not the user wears the shutter glasses 2 via the communication unit 162.

  For example, when a 2D image is displayed on a broadcast wave and the image is suddenly switched to a stereoscopic image, it is assumed that the user cannot wear the shutter glasses 2, and the user wears the shutter glasses 2. While it is not, the stereoscopic video cannot be recognized (viewed) as a three-dimensional image. Further, there are cases where a stereoscopic video cannot be viewed as a proper video unless glasses for stereoscopic viewing are generally worn.

  Therefore, in the DTV 1 of this embodiment, it is determined whether or not the user wears the stereoscopic viewing glasses, and the broadcast video is automatically recorded while the stereoscopic viewing glasses are not worn. Can do. Next, a configuration for executing this will be described.

  FIG. 3 is a block diagram illustrating an example of a configuration relating to stereoscopic video recording processing in the present embodiment.

  The control unit 156 includes a video discriminating unit 31, which can discriminate whether the broadcast video currently received by the DTV 1 is a 2D video or a stereoscopic video. . As an example of the discrimination method of the video discriminating unit 31, a flag (information) indicating whether or not the video is a stereoscopic video, which is included in the data signal of the broadcast wave, is read, and the video received based on this is read. A method for determining whether a 2D image or a stereoscopic image is available. In the present embodiment, this method is adopted, and the video discriminating unit 31 receives the data signal of the video currently received from the signal processing unit 100 and discriminates based on this data signal. The method for discriminating whether the video is a 2D video or a stereoscopic video is not limited to this, and a method of discriminating by analyzing the video itself may be considered. If the video discriminating unit 31 discriminates that the received broadcast wave video is a stereoscopic video, the video discriminating unit 31 notifies the glasses wearing detection unit 32 and the recording control unit 33 to that effect.

  The glasses wearing detection unit 32 has a function of detecting whether or not the user is wearing the shutter glasses 2. In the present embodiment, there are several methods for detecting the wearing of the glasses.

  First, there is a method of detecting based on a wearing state signal received from the shutter glasses 2 and indicating whether or not the shutter glasses 2 are worn by the user. The glasses wearing detection unit 32 can transmit a wearing state signal request to the shutter glasses 2 via the communication unit 162, and can receive the wearing state signal from the shutter glasses 2.

  Another detection method is a method of detecting the wearing of the user's glasses based on the user's image captured by the imaging unit 160. The glasses wearing detection unit 32 can analyze the video shot by the shooting unit 160 and determine whether the user in the video is wearing the shutter glasses 2. In this case, the glasses wearing detection unit 32 recognizes the user's shoulder, head shape, and the like from the captured video and determines whether or not the shutter glasses 2 are present at the recognized head position. Further, for example, a marker or the like may be provided on the shutter glasses 2 so that the glasses wearing detection unit 32 can easily detect them.

  As another detection method, a method of asking the user whether or not the shutter glasses 2 are worn can be considered. In this case, the DTV 1 displays an image indicating that the user asks whether or not the user is currently wearing the shutter glasses by OSD or the like, and the user answers by remote control operation.

  The glasses wearing detection unit 32 determines whether the user is wearing the shutter glasses 2 using at least one of the methods described above (detects the user wearing the shutter glasses 2). Then, the glasses wearing detection unit 32 outputs the result of this determination to the recording control unit 33.

  The recording control unit 33 has a function of controlling recording when a stereoscopic video is displayed. The recording control unit 33 can create an image for allowing the user to select whether or not to start recording when a stereoscopic video is displayed. This selection screen is output to an OSD (On Screen Display) signal generation unit 154, and is displayed so as to be superimposed on the video. An example of this selection screen is shown in FIG. FIG. 4 shows a state where a selection screen 41 is displayed on the display unit 120 for the user to select whether or not to automatically record a video when displaying a stereoscopic video. The user can select whether or not to perform automatic recording by the remote controller 117 while the selection screen 41 is displayed.

  Further, the recording control unit 33 has a function of controlling the recording process when the automatic recording start execution is selected using the selection screen 41. In this recording, the video / audio acquired from the broadcast wave is stored in the HDD 170. In the present embodiment, the storage destination is exemplified as the HDD 170, but the storage destination is not limited to this. For example, an external storage device of the DTV 1 such as an external storage device may be used as the storage destination.

  Next, the processing flow in this embodiment will be described.

  FIG. 5 is a flowchart showing an example of processing related to automatic recording in the present embodiment.

  First, the video discriminating unit 31 acquires (receives) a broadcast wave data signal (step S51).

  When obtaining the broadcast wave data signal, the video discriminating unit 31 discriminates whether or not the currently received broadcast wave video is a stereoscopic video based on the flag of the data signal (step S52). As this determination method, it may be determined based on a data signal, or may be determined by analyzing the video itself. When a stereoscopic video is provided by a broadcast wave, the acquired stereoscopic video is often transmitted in a specific video format such as side-by-side or top-bottom. When the video discriminating unit 31 analyzes the video of the broadcast wave and detects that this video is a specific video format such as Side-by-side, Top-bottom, etc., it discriminates that this video is a stereoscopic video. The method for discriminating stereoscopic images of the present embodiment is not limited to this, and various other methods are conceivable.

  When the video discriminating unit 31 discriminates that the broadcast wave video is a stereoscopic video image in step S52 (step S52: Yes), the glasses wearing detection unit 32 then determines whether or not the user wears the shutter glasses 2. The discrimination is performed (step S53), and the discrimination result is output to the recording control unit 33. As a determination method here, as described above, there are a method of determining mounting by receiving a signal related to the mounting state from the shutter glasses 2, and a method of determining mounting based on an image photographed by the photographing unit 160. Conceivable. Here, the video discriminating unit 31 may determine the wearing by performing communication with the shutter glasses 2 and photographing the user by using the fact that the video of the broadcast wave is discriminated as a stereoscopic video. Alternatively, for example, the glasses wearing detection unit 32 determines the wearing at a predetermined timing before that, and the discrimination result of the wearing of the glasses is output to the recording control unit 33 using the discrimination of the stereoscopic video as a trigger. good.

  In step S53, when the glasses wearing detection unit 32 determines that the user does not wear the shutter glasses 2 (step S53: No), the recording control unit 33 determines that the recording setting at the start of displaying the stereoscopic video is currently valid. It is determined whether or not (step S54). Whether or not to enable this setting is selected by the user using the screen of FIG.

  When the video discriminating unit 31 discriminates that the broadcast wave video is not a stereoscopic video image in step S52 (step S52: No), the spectacle wearing detection unit 32 discriminates that the user is wearing the shutter glasses 2 in step S53. In this case (step S53: Yes), or when the recording control unit 33 determines that the recording setting at the start of displaying the stereoscopic video is invalid (step S54: No), the DTV 1 receives the received broadcast wave video. Is displayed (step S55). At this time, when the received video is a 2D video, the DTV 1 executes and displays a predetermined process for displaying as a 2D video, and displays a stereoscopic video when the received video is a stereoscopic video. Execute the process and display it.

  In step S54, when the recording control unit 33 determines that the recording setting at the start of stereoscopic video display is invalid (step S54: Yes), the recording control unit 33 starts recording broadcast waves (step S54). S56).

  Then, the DTV 1 displays the received broadcast wave video (step S57). At this time, the video of the broadcast wave is a stereoscopic video, and the DTV 1 may display this video by a stereoscopic video display method, or performs a conversion process for displaying this video as a 2D video, and 2D It may be displayed as a video.

  Next, the glasses wearing detection unit 32 determines whether or not the user has worn the shutter glasses 2 (step S58). While the user's wearing of the shutter glasses 2 is not detected (while it is determined that the user is not wearing) (step S58: No), the process returns to step S57, and the DTV 1 continues to display the video.

  In step S58, when the glasses wearing detection unit 32 detects that the user wears glasses (step S58; Yes), the recording control unit 33 automatically reproduces and displays the recorded video (step S59). The recording control unit 33 has a reproduction unit (reproduction means) for reproducing the recorded video, and the recording control unit 33 continues to record the video even after the reproduction of the video recorded by the reproduction unit is started. For example, when the playback position of the recorded video catches up with the currently broadcast video due to, for example, fast-forwarding of the recorded video, the recording control unit 33 ends the playback of the recorded video, and the DTV 1 displays a normal broadcast wave video.

  With the above processing, even when a stereoscopic video is broadcast when the glasses for stereoscopic viewing are not worn, the recorded video can be viewed, so the user can view the stereoscopic video as a stereoscopic from the beginning. Can do. In addition, by reproducing the video simultaneously with the recording of the stereoscopic video, if the reproduction catches up, the user can view the broadcast wave as it is.

  Furthermore, when the user wears the stereoscopic glasses, the reproduction of the stereoscopic video that has been recorded automatically is started, thereby saving the user from having to issue a reproduction instruction. In this case, if the user wears stereoscopic glasses when the stereoscopic video is displayed, it is considered that the user has an intention to view the currently displayed video as a stereoscopic image. In addition, since the stereoscopic video is reproduced, it is possible to save the user from having to issue a reproduction instruction.
