It is a flowchart which shows operation | movement of the television shown in FIG. It is a top view which shows the structure of the display apparatus which concerns on other embodiment of this invention.

<Embodiment 1>
An embodiment of the present invention will be described below with reference to FIGS.

[Configuration of TV]
FIG. 1 is a top view illustrating a configuration example of the television 1 according to the present embodiment. As shown in FIG. 1, the television (display device) 1 includes a display unit 10, a camera (imaging unit) 20, and a human sensor 30. In FIG. 1, H 1, H 2, and H 3 indicate users (people) who view the television 1.

  A display (not shown) is provided on the front surface of the display unit 10 to display content supplied from the outside, content stored in a storage device built in the television 1, and the like. Further, the display unit 10 incorporates a main control unit 100 described later.

  The content supplied from the outside is, for example, content supplied by an analog broadcast signal or a digital broadcast signal, supplied from a USB memory, SD card, HDD, DVD player / recorder, BD player / recorder, etc. connected to the television 1 Content, content supplied via the Internet, and the like.

  The camera 20 is a device for photographing the face of the user who views the television 1. The camera 20 is provided at the center of the upper surface of the television 1. Examples of the camera 20 include a USB camera and a CCD camera. In FIG. 1, an angle of view indicating an area (shootable area) that can be actually captured by the camera 20 as an angle is denoted by φ. As described above, USB cameras, CCD cameras and the like generally have an angle of view of less than 90 °.

  The television 1 also includes a drive unit 21 for changing the direction of the camera 20 (shown in FIG. 2 described later). By changing the direction of the camera 20 by the drive unit 21, the shootable area can be changed. Thereby, the user detected by the human sensor 30 can be photographed. Note that the camera 20 performs shooting when it acquires a shooting instruction from a camera control unit 104 described later, and transmits the obtained image information to the image processing unit 105.

  The human sensor 30 is a sensor that detects whether or not a user exists within the detectable region, and identifies the position of the user when the user exists. The human sensor 30 is provided at the center of the upper surface of the television 1. The human sensor 30 can be, for example, a human sensor that makes it possible to detect in which region a person is present by collecting a plurality of human sensor devices (for example, http://www.tapcorp.com). /ten/ten135/TME-2.pdf (searched on May 6, 2010). In FIG. 1, the detectable area angle indicating the detectable area of the human sensor 30 is indicated by θ. In addition, since the detectable area angle θ is wider than the angle of view φ of the camera 20, the human sensor 30 can detect a user who exists in a range where the camera 20 cannot photograph at a time. In general, the detectable area angle θ at which the human sensor 30 can sense the user is wider than the angle of view φ of the camera 20. As described above, in the present invention, even if an inexpensive camera with a narrow angle of view is used, a human sensor can efficiently shoot a user in a wide range. The apparatus can be provided at low cost.

  The human sensor 30 may be set so that the power can be switched on and off independently of the other members of the television 1. Switching between power ON and OFF may be performed directly by a user operation, or may be automatically performed according to an application to be executed.

  The television 1 includes both the camera 20 and the human sensor 30 so that a wide range of users can be photographed.

  For example, when the human sensor 30 and the drive unit are not provided, only the user H1 existing in the range of the field angle φ of the camera 20 can be photographed. However, since the human sensor 30 and the drive unit are provided, the human sensor 30 detects the presence of the users H2 and H3 and specifies the position, and the specified position is within the range of the field angle φ of the camera 20. Since the drive unit can change the direction of the camera 20 so as to be within the range, the camera 20 can photograph the users H2 and H3.

  Thereby, the application provided to the user can be provided not only to the user H1 but also to the users H2 and H3 using the image data of the user photographed by the camera 20.

(Configuration for identifying users)
Next, the configuration of the television 1 will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the television 1.

  As shown in FIG. 2, the television 1 includes a camera 20, a drive unit 21, a human sensor 30, a storage unit 40, and a main control unit 100.

  The drive unit 21 is a mechanism that drives the camera 20 so that the shootable area of the camera 20 changes.

  The storage unit 40 stores user information. The user information includes, for example, the name of the user who uses the television 1 (user name), the user face information indicating the features of the user's face, such as the eyes extracted from the image information of the user photographed by the camera 20 and the position of the eyebrows. Etc. are included. Note that the user face information is not limited to information indicating facial features such as the eyes and the position of the eyebrows, and may be information indicating the facial features of the user. In addition, the storage unit 40 stores applications that can be used in the television 1 in advance. The storage unit 40 stores user information and user-specific settings (setting information) uniquely set by the user to execute the application by a user registration unit (not shown) in association with each other. That is, the user face information is associated with the user-specific setting in the storage unit 40.

  The main control unit 100 comprehensively controls various configurations of the television 1. The main control unit 100 includes a user instruction acquisition unit 101, an application control unit 102, a human sensor control unit 103, a camera control unit 104 (a drive unit control unit and a photographing control unit), and an image processing unit 105.

The user instruction acquisition unit 101 receives an instruction (user instruction) from a user performed by operating a remote controller (not illustrated) or an operation unit (not illustrated) provided in the television 1, and contents of the received user instruction To determine the supply destination of the user instruction. For example, when the acquired user instruction is an application execution instruction, the user instruction acquisition unit 101 supplies an execution instruction to the application control unit 102. The user instruction acquisition unit 101 acquires user-specific settings via a remote controller or an operation unit. The user inputs user-specific settings for executing the application to the remote controller or the operation unit. The user instruction acquisition unit 101 acquires user-specific settings and supplies them to the user registration unit. On the other hand, when the user inputs user-specific settings, the user also inputs which user information the user corresponds to. The user registration unit acquires the user information, and stores the user-specific setting and the user information in the storage unit 40 in association with each other. As a result, the user-specific setting is associated with the user face information.

  The application control unit 102 is a unit that executes the application specified by the execution instruction when the application execution instruction is acquired from the user instruction acquisition unit 101. Further, the application control unit 102 performs user face authentication based on the user face information acquired from the image processing unit 105. Thereby, user face information corresponding to the user photographed by the camera is selected from the user face information stored in the storage unit 40. Note that specific processing of face authentication will be described later. That is, as a result of the face authentication, the application control unit 102 acquires a user-specific setting associated with one user face information stored in the storage unit 40, and sets the user-specific setting as the user-specific setting. Run the application based on.

  The human sensor control unit 103 turns on the human sensor 30 necessary for specifying the user's position independently of the other members of the television 1, and the human sensor 30 not required for specifying the user's position. Is a means to turn OFF. When there are a plurality of human sensors 30, the human sensor control unit 103 may be able to individually control ON and OFF for each human sensor 30.

  The camera control unit 104 allows the user present in the detectable area of the human sensor 30 to photograph the camera 20 when the user present in the detectable area of the human sensor 30 does not exist in the imageable area of the camera 20. This is means for driving the drive unit 21 so as to exist in the region. In addition, the camera control unit 104 transmits a shooting instruction to the camera 20, and also exists in a shootable region by driving the drive unit 21 in advance and a user existing in the shootable region of the camera 20. This is means for causing the camera 20 to photograph the user who has decided to do so.

  The driving of the driving unit 21 by the camera control unit 104 is repeated until all of the users detected by the human sensor 30 are photographed by the camera 20. Specifically, the camera control unit 104 temporarily determines the number of users that are detected by the human sensor 30 and that are in a region that can be detected by the human sensor 30 and outside the image capturing region of the camera 20. To remember. Next, the camera control unit 104 drives the drive unit 21 to transmit a shooting instruction to the camera 20 every time a user comes within the imageable area. The camera 20 shoots the user every time a shooting instruction is acquired. The camera control unit 104 temporarily stores the number of people photographed by the camera 20 separately. The camera control unit 104 and the camera 20 collate the number of photographed people with the number of users stored first, and repeat the operations from driving to photographing until they match. As a result, all the users detected by the human sensor 30 are detected by the camera 20. Note that the drive unit 21 always drives and shoots an image so that an area in which a person has been detected in the past is included in the imaging range of the camera 20, and a human sensor for an area in which no person has been detected in the past 30 may be detected.

  The image processing unit 105 is a means for extracting user face information indicating features of the user's face such as the user's eyes and eyebrow position from the user's image information supplied from the camera 20. Note that the user face information is not limited to information indicating the user's face characteristics such as the eyes and the position of the eyebrows, and may be information indicating the user's face characteristics.

(Face recognition)
Next, face authentication processing in the application control unit 102 will be described.

When acquiring the user image information supplied from the camera 20, the image processing unit 105 extracts the user face information from the user image information and supplies the extracted user face information to the application control unit 102.

  The application control unit 102 collates the acquired user face information with user face information included in all user information stored in the storage unit 40. In addition, since this collation method is well-known, the description is abbreviate | omitted. As a result of the collation, when the matching rate between any of the user face information stored in the storage unit 40 and the user face information acquired from the image processing unit 105 is higher than a predetermined value (the matching rate is high), The application control unit 102 reads from the storage unit 40 user-specific settings stored in association with user face information having a high matching rate. The application control unit 102 executes the application based on the read user-specific setting.

  When there are a plurality of users who are watching the television 1, the application control unit 102 reads the user-specific settings of the application associated with each user information. The user information stored in the storage unit 40 may have a priority set in advance. When the priority is set in advance, the application control unit 102 selects an application based on the user-specific setting associated with the user information having the highest priority among the plurality of user-specific settings read from the storage unit 40. Just do it.

  In the present embodiment, when there are a plurality of users who are watching the television 1, a configuration is shown in which an application is executed based on user-specific settings associated with user information having the highest priority. The invention is not limited to this.

  For example, it is good also as a structure which performs an application in order based on each of several user specific setting read from the memory | storage part 40. FIG. Further, among the plurality of user-specific settings read from the storage unit 40, a configuration may be adopted in which the application is executed based only on settings that are set in common in at least two or more user-specific settings. When a plurality of read user-specific settings are represented by numerical values or levels, a configuration in which an application is executed with an average of the setting values can be adopted.

  In addition, by displaying the user name associated with each of the user information associated with the plurality of user-specific settings read from the storage unit 40 on the display unit 10, the application is based on the user-specific settings set by which user. It is also possible to adopt a configuration in which it is possible to select whether to execute.

(Operation of camera and motion sensor)
Next, the operation of the television 1 will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the television 1.

  As shown in FIG. 3, when the user selects to execute an application that requires user shooting (step S1), the user instruction acquisition unit 101 requires the application control unit 102 to perform user shooting. The application execution instruction is supplied.

  The application control unit 102 that has acquired the execution instruction notifies the human sensor control unit 103 to turn on the human sensor 30 necessary for specifying the user, and the human sensor control unit 103 specifies the user. The human sensor 30 necessary for the operation is turned on. The human sensor 30 identifies each position of the user who is viewing the television 1 (step S2), and supplies the identified position of the user to the camera control unit 104.

The camera control unit 104 first determines that the camera 20 when the user is present in advance in the imageable area.
The shooting instruction is transmitted to the camera 20 without changing the orientation of the camera 20, and the camera 20 performs shooting. It should be noted that whether or not the user exists in advance in the shootable area may be recognized by the camera 20, or if the shootable area and the detectable area of the human sensor 30 overlap, the human sensor 30. You may recognize by. Next, when the human sensor 30 detects the user outside the range of the shootable area, the driving unit 21 is driven so that the user detected by the human sensor 30 exists in the shootable area of the camera 20. To change the direction of the camera 20. Then, by driving the drive unit 21, the camera 20 is caused to photograph the user who has existed in the photographable area. The camera 20 supplies the captured user image to the image processing unit 105 (step S3).

  The image processing unit 105 extracts user face information from the acquired user image information, and supplies the extracted user face information to the application control unit 102. The application control unit 102 performs user face authentication. Specifically, user information including user face information having a high matching rate with the supplied user face information is selected from all user information stored in the storage unit 40 (step S4).

  The camera control unit 104 determines whether or not the camera 20 has photographed all the users detected by the human sensor 30 (step S5). If it is determined that all the users detected by the human sensor 30 have not been photographed (NO in step S5), the camera control unit 104 drives the camera 20 so as to photograph a user who has not been photographed. The unit 21 is driven. The camera 20 shoots a user who is present in the shootable area by driving the drive unit 21 based on an instruction from the camera control unit 104. That is, steps S3 to S5 are repeated until all users are photographed.

  If it is determined that all users detected by the human sensor 30 have been photographed (YES in step S4), the camera control unit 104 notifies the application control unit 102 that all users have been photographed. The application control unit 102 reads the application selected by the user from the storage unit 40, and sets user-specific settings associated with user information including user face information having a high matching rate with the user face information supplied from the image processing unit 105. (Step S6).

  In the present embodiment, the configuration is shown in which the human sensor control unit 103 turns on the human sensor 30 necessary for specifying the user when an application that requires user shooting is selected. The present invention is not limited to this. For example, the information indicating the position of the user only when an application that requires the user's identification is selected while the human sensor is kept on. May be obtained from the human sensor 30. In addition, regardless of whether or not an application that requires the user's identification is selected, the information indicating the position of the user is continuously acquired from the human sensor 30 while the human sensor is turned on. It is good.

(application)
An example of an application is an application that displays a favorite image quality.

  The application for displaying the preferred image quality display stores the user information of the user who views the television 1 and the image quality setting value (setting information) for displaying the video with the image quality preferred by the user. This is an application that makes it possible to display a video with an image quality preferred by the user when the matching rate between the user face information extracted from the image information of the photographed user and the stored user face information is high.

  For example, when an application that displays a favorite image quality is selected by the user and a plurality of users are specified by face authentication, the application that displays the favorite image quality is associated with the user face information of each specified user. The image quality setting value that is the user-specific setting for the image is read from the storage unit 40. When the priority is set in the user information associated with the read image quality setting value, the application control unit 102 associates with the user face information in the user information in which the highest priority is set. The image quality is adjusted based on the existing image quality setting value. Further, a configuration may be adopted in which the image quality is adjusted based on a value obtained by averaging the image quality setting values of all the specified users regardless of whether or not the priority is set.

  Further, as another example of the application, user information of a user who views the TV 1, an image quality adjustment value (setting information) for displaying the image quality preferred by the user, and a program frequently viewed by the user An application that stores programs (setting information) and displays images reflecting the image quality settings of a plurality of users captured by the camera 20 at regular intervals, and each user frequently views An application for performing screen division display, in which a program on the television 1 is divided and displayed, respectively, can be cited.

  For example, when an application that performs split screen display is selected by the user and a plurality of users are identified by face authentication, the user related to the application that performs split screen display is associated with the user face information of each identified user. The image quality adjustment value and the regular program, which are unique settings, are read from the storage unit 40. The application control unit 102 displays the video of the regular program whose image quality is adjusted according to each read image quality adjustment value in each area of the screen of the television 1 divided by the number of users viewing the television 1. Display each one.

  Furthermore, the application described in JP2009-267445A can be given as an example.
