A viewing playback unit 17 with an order of the decoder, and has a structure in control unit 18 for controlling the above respective units.

  The control unit 18 has a face identification function for identifying a face image captured by the imaging unit 11 to identify an individual, and a viewing title acquisition function for acquiring a title such as video content being reproduced by the viewing reproduction unit 17. Although provided, a face identification unit and a viewing title acquisition unit may exist separately from the control unit 18. Note that the communication terminal 3 and the communication terminal 4 have the same configuration.

A method for registering person registration information, which is information necessary for using a communication terminal, will be described.
FIG. 3 is a specific example of a table of person registration information that is management information of users of communication terminals. The person registration information table is stored in the storage unit 12 and includes a person identifier, a person name, and face identification information. The person identifier is a unique identifier assigned to a user who uses the communication terminal, and is assigned by the communication terminal. The person name is information input by an operation of the operation input unit 13 by the user. The face information is information generated by extracting the feature points of the user's face by the control unit 18 from the video of the user photographed by the photographing unit 11.

  FIG. 4 is an example of a processing flow showing a procedure of registration processing of person registration user information. In FIG. 1, when a user uses the communication terminal 1 for the first time, the user first performs an operation of registering his / her information in the communication terminal 1. When the user performs an operation for starting registration using the operation input unit 13, the communication terminal 1 displays a message prompting the user to photograph the face of the user on the display unit 14 (step S101). Subsequently, the photographing unit 11 starts photographing (step S102).

  Whether or not a face is included in the video imaged by the imaging unit 11 is identified and determined by the control unit 18 (step S103). If the photographed video does not include a face, the photographing unit 11 performs photographing until the face is photographed.

  When the control unit 18 determines that the face is included in the captured video, the control unit 18 determines the feature point of the face video in order to determine whether the user is already registered. The extracted face information is generated, compared with the face information included in the person registration information table stored in the storage unit 12, and searched for matching face information (step S104).

  If it has already been registered, this registration process is terminated. If it is not registered, a message prompting the user to input the person's name is displayed on the display unit 14 and waits until the user inputs a person name using the operation input unit 13 (step S105). When an operation for completing the input is performed, the face information and the person name are recorded in the person registration information table stored in the storage unit 12 (step S106), and the process is terminated.

Next, a calling method and a method for acquiring telephone directory information from a communication terminal as a communication destination will be described.
FIG. 5 is a specific example of a telephone directory information table in which information for communicating with other communication terminals is described. The telephone directory information table is stored in the storage unit 12 and is composed of a user person identifier, a communication destination designation address, a communication destination person identifier, and a person name. The user person identifier is the person identifier of the user who uses the information in the corresponding row of the telephone directory information table. The communication destination designation address is information for designating a communication destination, such as a SIP (Session Initiation Protocol) URI (Uniform Resource Identifier) and a telephone number.

  The communication destination person identifier is a person identifier of a person to be called by designating the communication destination designation address. The above information is acquired by performing transmission / reception of data with a communication terminal as a communication destination in addition to being input by the operation input unit 13.

  Here, as an example, a user whose person identifier is A1 (hereinafter referred to as user A1) uses the communication terminal 1, and a user whose person identifier uses the communication terminal 3 is B1 (hereinafter referred to as user B1). The procedure for making a call is described. It is assumed that the mutual information is not recorded in the telephone directory information table stored in the storage unit 12 of the communication terminal 1 and the communication terminal 3.

  First, when the user A1 performs an operation for starting a call using the operation input unit 13 of the communication terminal 1, the photographing unit 11 starts photographing the face of the user. Next, the control unit 18 generates face information of the face of the user being photographed, searches for the face information included in the person registration information table stored in the storage unit 12, and before the communication terminal 1. Identify who the users are. When there are a plurality of users in the shooting range, the control unit 18 determines who each is.

  The display unit 14 reads the specified person name of the user from the person registration information table stored in the storage unit 12 and displays it as a user list on the calling side. When it is determined that there are a plurality of calling side users within the shooting range, and there is a user who does not intend to participate in the call, a user on the calling side using the operation input unit 13 Specify the person name from the list and delete it.

  The user A1 uses the operation input unit 13 to input the communication destination designation address of the user B1. The communication unit 10 transmits call information for calling the communication terminal 3 designated by the communication destination designation address. This call information includes the person name and person identifier of the user A1. If there are a plurality of calling users, a plurality of person identifiers are included.

  When the communication unit 10 of the communication terminal 3 receives the call information, the communication unit 10 temporarily stores the received information in the storage unit 12 of the communication terminal 3, and further reads out the telephone book information table stored in the storage unit 12. It is searched whether the identifier A1 is included in the telephone directory information table.

  When the communication unit 10 of the communication terminal 3 determines that the person identifier A1 is not included in the telephone directory information table, the communication unit 10 reads the person registration information table stored in the storage unit 12 and configures the person registration information table. Among them, all the person identifiers and person names are transmitted to the communication terminal 1 on the calling side.

  When the communication terminal 1 on the calling side receives the information transmitted from the communication terminal 3, the information and the information at the time of the call are combined and recorded in the telephone directory information table stored in the storage unit 12 of the communication terminal 1. To do. The information recorded in the telephone book information table is that the user identifier is the person identifier of the user A1, the communication destination designation address is the address input at the time of calling, and the communication destination person identifier and the person name are transmitted from the communication terminal 3. The person identifier and the person name included in the recorded information.

  Next, all the names of persons included in the information received from the communication terminal 3 are displayed on the display unit 14 in a state where they can be listed. The user A1 designates the name of the person who wants to talk from the list of person names using the operation input unit 13. At this time, a plurality of persons may be designated.

  When the name of a person who wants to talk is specified in the communication terminal 1, the communication unit 10 of the communication terminal 1 transmits the person identifier corresponding to the specified information to the communication terminal 3 on the called side as an incoming call specified person identifier. When the communication terminal 3 receives transmission information from the communication terminal 1, the person identifier included in the received information and the calling person identifier and person name included in the temporarily recorded information are stored in the storage unit 12. Recorded in the phonebook information table.

  In addition, the voice input / output unit 15 or the display unit 14 notifies the calling person name and the called person name. As described above, the call processing from the user A1 of the communication terminal 1 to the user B1 of the communication terminal 3 and the acquisition processing of the information in the telephone directory information table are completed.

  Next, a description will be given of a calling method in the case where mutual information is registered in the telephone directory information table between communicating users. Here, a procedure in which the user A1 uses the communication terminal 1 to make a call to the user B1 who uses the communication terminal 3 will be described. When the user A1 performs an operation for displaying the phone book information using the operation input unit 13 of the communication terminal 1, the photographing unit 11 of the communication terminal 1 photographs the face of a person within the photographing range.

  The control unit 18 specifies the person identifier of the user A1 from the captured video. The display unit 14 reads the phone book information table recorded in the storage unit 12, and from the information included in the phone book information table, information in which the user's person identifier is recorded in the user person identifier item. Extract only and display person name.

  When the user A1 designates the name of a person who wants to talk using the operation input unit 13, the display unit 14 displays a list of person names having the same communication destination designation address as the designated person. User A1 designates the name of the person who wants to talk from the list of displayed person names using the operation input unit 13. Multiple person names may be specified.

  When the user A1 performs a call operation using the operation input unit 13, call information for calling a communication terminal of a communication destination is transmitted from the communication unit 10. The call information includes a person identifier corresponding to the designated person name as the called party designated person identifier.

Next, a description will be given of a first embodiment of a method for determining a communication terminal that performs an incoming call notification when an incoming call is received.
FIG. 6 is a specific example of a table of home communication terminal information for managing a plurality of home communication terminals. The in-home communication terminal information is stored in the storage unit 12 and includes a communication terminal name, an IP address, and parent device information. The communication terminal name is a name for identifying each communication terminal when a plurality of communication terminals are installed in the same house, and is assigned to each communication terminal.

  The IP address is an IP address set for each communication terminal. The parent device information is information indicating whether the communication terminal operates as a parent device or a child device. Information of each item is input by the operation input unit 13 of the communication terminal.

  FIG. 7 is a specific example of a presence / absence information table including information on whether a user exists in front of a communication terminal. The presence / absence information table is stored in the storage unit 12 of the communication terminal set as the parent device in the parent device information item of the in-home communication terminal information. The presence / absence information table includes a communication terminal name, a current user identifier, and an assigned person identifier.

  As the communication terminal name, the communication terminal name of the in-home communication terminal information is recorded. In the items of current user identifier and assigned person identifier, one, a plurality of person identifiers or none are recorded. The current user identifier is information indicating which user is currently using a certain communication terminal, and is updated by the photographing unit 11, the control unit 18, and the storage unit 12. The assigned person identifier is information that associates the communication terminal with the user, and is information that the user inputs using the operation input unit 13.

  Next, a method for updating the current user identifier will be described. When the photographing unit 11 and the control unit 18 of the communication terminal identify that the user's face is present within the photographing range, the photographed usage is compared with the face information in the person registration information table recorded in the storage unit 12. Identify the person. This process is always performed regardless of the operation by the user.

  In the case of a communication terminal set as a master unit, the person identifier of the identified user is recorded and updated in the item of the current user identifier of the presence / absence information table stored in the storage unit 12. In the case of a communication terminal set as a slave unit, the communication terminal name and the identified person identifier of the user are transmitted to the master unit.

  When this information is received by the communication terminal set as the parent device, the received person identifier is recorded in the item of current user identifier of the communication terminal in the presence / absence information table stored in the storage unit 12. The presence / absence information table is updated by the above procedure.

  FIG. 8 is an example of a processing flow showing the procedure of the incoming call processing in the communication terminal having the presence / absence information table. Here, a case where a call is made from the user A1 of the communication terminal 1 of FIG. 1 to the communication terminal 3 and the user B1 of the communication terminal 4 will be described. It is assumed that the communication terminal 3 is set as a parent device and the communication terminal 4 is set as a child device.

  When the communication terminal 3 as the master unit receives the call information from the communication terminal 1, the communication terminal 3 reads the incoming call designated person identifier included in the call information, and the person identifier is stored in the storage unit 12. It is searched whether it is included in the item of the current user identifier in the presence / absence information table (step S201).

  If it is included (Y in step S202), the communication terminal name that matches the person identifier is acquired from the presence / absence information table (step S203). If not included (N in step S202), the process proceeds to the process in FIG. 10 (step S212).

  When the communication terminal name is acquired in step S203, it is determined whether the communication terminal name is that of the parent device (step S204). If the result of the determination is the parent device (Y in step S204), an incoming call notification for calling the user is performed (step S205).

  The incoming call notification is performed by extracting a corresponding person name from the person registration information table stored in the storage unit 12 based on the incoming call designated person identifier and presenting the person name as video information on the display unit 14. The user is notified by voice output by the voice input / output unit 15 or the like.

  If the result of determination in step S204 is a slave unit (N in step S204), the master unit transmits an incoming call notification request to the communication terminal (slave unit) (step S206). The incoming call notification request is information transmitted to cause the slave unit to perform incoming call notification processing.

  In step S205, as a result of the incoming call notification, if the user performs a response operation to the incoming call within the predetermined time (for example, 10 seconds) (Y in step S207), the incoming call notification process is performed. Is completed, and response processing such as connection for a call is performed (step S208). Since the response processing part is the same as the conventional technique, the description thereof is omitted.

  In step S206, when an incoming call notification request is transmitted to the communication terminal set as the slave unit, as a subsequent process, response information indicating that the user has performed a response operation on the communication terminal of the slave unit Waiting for reception (step S209). If the responded information is received within a certain time (Y in step S210), the communication terminal of the parent device ends the process.

If the response completion information cannot be received within a certain time (N in Step S210), a call notification stop request is transmitted to the communication terminal of the child device (Step S211). Thereafter, the process proceeds to the process of FIG. 10 (step S212).
When there are a plurality of person identifiers included in the call information, the above processes are performed one by one in parallel.

  FIG. 9 is an example of a processing flow showing a processing procedure when an incoming call notification request is received at the communication terminal of the slave unit. When the communication terminal (slave device) receives the incoming call notification request (step S301), the communication terminal (slave device) issues an incoming call notification (step S302). The incoming call notification method is the same as the processing method of the communication terminal set as the master unit.

  When the user who notices the incoming call notification performs a response operation using the operation input unit 13 (Y in step S303), the responded information is transmitted to the communication terminal of the base unit (step S304), and the incoming call is received. The notification process is completed, and a response process such as connection for a call is performed (step S306). Since the response processing part is the same as the conventional technique, the description thereof is omitted.

  If no response operation has been performed (N in step S303), it is determined whether an incoming call notification stop request has been received from the parent device (step S305). If an incoming call notification stop request is received (Y in step S305), the process ends. If the incoming call notification stop request has not been received (N in step S305), the incoming call notification is continued (step S302).

  FIG. 10 is an example of a processing flow showing a procedure for performing an incoming call process based on the assigned person identifier included in the presence / absence information table. This processing flow is processing that continues from step S212 in FIG. 8, and step S401 is only a step that indicates that the processing has shifted from S212.

  As a result of performing the incoming call process based on the current user identifier included in the presence / absence information table of FIG. 8, the communication terminal that has reached the steps from S212 to S401 stores in the storage unit 12 based on the incoming call designated person identifier. The assigned person identifier in the stored presence / absence information table is searched (step S402). As a result of the search, if the communication terminal (hereinafter referred to as “assigned communication terminal”) in the row in which the callee designated person identifier matches the assigned person identifier is the parent device (Y in step S403), an incoming call notification is performed (step S403). S404). If the assigned communication terminal is a child device (N in step S403), the communication terminal (parent device) transmits an incoming call notification request to the communication terminal (child device) (step S405).

  In step S404, as a result of the incoming call notification, if the user performs a response operation to the incoming call within the predetermined time (Y in step S406), the incoming call notification process is completed, Response processing such as connection is performed (step S407). Since the response processing part is the same as the conventional technique, the description thereof is omitted.

  If the user does not respond to the incoming call at the communication terminal within a predetermined time (N in step S406), the process proceeds to the incoming call notification process at all the communication terminals included in the in-home communication terminal information ( Step S410). The incoming call notification process in all the communication terminals is the same as that in the conventional technology, and thus the description thereof is omitted.

  When the incoming call notification request is transmitted to the communication terminal set as the slave unit (step S405), as the subsequent processing, the response completed information indicating that the user has performed a response operation on the communication terminal of the slave unit. Waiting for reception (step S408). If the response completion information is received within a certain time (Y in step S409), the communication terminal of the parent device ends the process.

If the response completion information cannot be received within a certain time (N in Step S409), the process proceeds to Step S410, and the incoming call notification process is performed in all the communication terminals included in the in-home communication terminal information.
As described above, the incoming call notification process according to the place where the user is present at the time of the incoming call is possible.

Next, a second embodiment which is a calling method using the presence / absence information table will be described.
FIG. 11 is a specific example of a phone book information display screen using the presence / absence information table. The screen includes a person name and a presence / absence information table of a communication terminal as a communication destination. The person name is information included in the telephone directory information table of the calling communication terminal. The presence / absence information table is information on the communication terminal of the user having the person name, and is acquired from the communication terminal of the user having the person name by the communication terminal on the calling side.

  Hereinafter, a processing procedure for displaying the phone book information using the presence / absence information table will be described. When the user A1 performs an operation of displaying the phone book information using the operation input unit 13 of the communication terminal 1, the communication terminal 1 reads the phone book information table from the storage unit 12, and stores the information contained in the phone book information table. Only information with the person identifier A1 is extracted. The communication terminal uses the communication unit 10 to transmit request information for requesting the presence / absence information table to the communication destination designation address included in the extracted telephone directory information.

  The request information includes an incoming call designated person identifier. A plurality of incoming call designated person identifiers may be included. The communication terminal 3 that has received the request information searches for the current user identifier included in the presence / absence information table stored in the storage unit 12 based on the incoming call designated person identifier included in the request information. As a result of the search, if there is a current user identifier that matches the incoming call designated person identifier, it indicates that the person indicated by the person identifier exists in front of one of the communication terminals (hereinafter referred to as presence). .

  When there is no current user identifier that matches the incoming call designated person identifier, it indicates that the person indicated by the person identifier does not exist in front of any communication terminal (hereinafter referred to as leaving). The communication terminal 3 transmits the search result to the communication terminal 1 as a table (hereinafter referred to as “acquisition presence / absence information table”) in a format that associates an incoming call designated person identifier with presence or absence.

  When the communication terminal 1 receives the acquisition presence / absence information table of the communication terminal 3, the person name extracted by the person identifier of the user A 1 from the telephone directory information table of the communication terminal 1 and the acquisition presence / absence of the communication terminal 3 are displayed on the display unit 14. The presence or absence information extracted from the rejection information table is displayed in a combination based on an incoming call designated person identifier. This process is performed for all communication destination designation addresses included in the telephone directory information table extracted by the communication terminal 1.

By the above procedure, display combining the telephone directory information and presence / absence information table shown in FIG. 11 can be performed. The user performs a call operation by designating the displayed person name using the operation input unit 13 of the communication terminal 1.
As described above, it is possible to make a call by confirming the presence / absence of the user on the called side at the calling side communication terminal without operating the called side communication terminal.

Next, an incoming call processing method using user history information will be described.
FIG. 12 is a specific example of a table of user history information indicating which communication terminal the user has used for how long. The user history information table is stored in the storage unit 12 and includes a communication terminal name, a person identifier, and an accumulated usage time. The information that enters the communication terminal name item in the user history information table is the same as the communication terminal name in the in-home communication terminal information. The information entered in the person identifier item is the same as the person identifier in the person registration information table. The accumulated use time is information indicating how much time has been used, and the information is updated by the photographing unit 11 and the control unit 18.

  Hereinafter, a method for updating the user history information table will be described. The photographing unit 11 and the control unit 18 of the communication terminal 1 perform photographing and face identification at a certain time interval (here, X seconds) to identify a user. When the user is specified, X seconds is added to the accumulated usage time of the corresponding row of the communication terminal name in the user history information table and the corresponding column of the specified person identifier of the user. As a result, the time when the user uses the communication terminal is recorded in the user history information table and updated.

  FIG. 13 is an example of a processing flow showing an incoming call processing procedure using the user history information table. This processing flow shows processing inserted between S212 of FIG. 8 and S401 of FIG. 10 which is the processing flow of the first embodiment. In this embodiment, when the process reaches step S212, the process proceeds to S501 instead of proceeding to S401.

  The process proceeds to S501 when the presence / absence information does not include the calling designated person identifier (N in S202), or when the incoming call notification is not responded within a certain time (N in S207), or from the slave unit. This is a case where the master unit has not received the responded information (N in S210).

  In FIG. 1, when a user A1 makes a call to a user B1 who uses the communication terminal 3 and the communication terminal 4 using the communication terminal 1, the call information including the incoming call designation identifier from the communication terminal 1 is stored in the parent information. The communication terminal 3 set as a machine receives. Subsequent processing is the same as the processing flow of FIG. 8 except for S212. When the process reaches S212, the process proceeds to step S501 of the process flow of FIG.

  Step S501 is only a step indicating that the process has shifted from S212. In step S502 following S501, the user history information table stored in the storage unit 12 of the communication terminal 3 is searched based on the callee designated person identifier, and the accumulated time information is extracted. The communication terminal name of the corresponding line with the longest time length is acquired from the extracted accumulated time information.

Based on the acquired communication terminal name, a communication terminal that performs call notification is determined. Since a series of subsequent processes in steps S503 to S510 are the same as steps S204 to S211 in FIG. In step S511, the process proceeds to S401, and the process proceeds to an incoming call process based on the assigned person identifier. Since the processing after S401 has already been described, a description thereof will be omitted.
By the above procedure, the incoming call notification can be performed at the communication terminal that the user has used for the longest time.

Next, a calling method using viewing history information will be described.
FIG. 14 is a specific example of a viewing history information table in which a history of video content viewed by a user is recorded. The viewing history information table is stored in the storage unit 12 and includes items including a person identifier, a title, and a viewing date, and is generated and updated when the user views the video content using the viewing playback unit 17. Is done. The item of the person identifier is the same as the person identifier in the person registration information table. The title and viewing date items are information related to video content.

  Hereinafter, a method for updating the viewing history information table will be described. The person identifier in the viewing history information table is controlled by photographing the face of the user who is being viewed by the photographing unit 11 at a certain time interval (for example, X seconds) when the viewing / reproducing unit 17 is reproducing the video content. This is obtained by specifying the user by the unit 18. The title and viewing date are acquired from the viewing title acquisition unit 19.

  Next, a procedure for making a call using the viewing history information table will be described. When the user performs a display operation of the phone book information using the operation input unit 13 of the communication terminal 1, the control unit 18 identifies and specifies the user using the photographing unit 11 and the storage unit 12.

  Next, based on the specified person identifier of the user, a user person identifier item in the telephone directory information table stored in the storage unit 12 is searched, and a communication destination designation address and a communication destination person identifier are extracted. . The communication terminal 1 transmits the request information of the viewing history information table to the extracted communication destination designation address. The request information includes the extracted communication destination person identifier.

  The communication terminal that has received the request information reads the viewing history information table from the storage unit 12 of the corresponding communication terminal, searches the person identifier item of the table by the communication destination person identifier, and extracts the corresponding row. When the extraction process ends, the extracted viewing history is transmitted to the communication terminal 1. When the communication terminal 1 receives the viewing history information table, it is temporarily recorded in the storage unit 12.

  The communication terminal 1 compares the viewing history information table of the user A1 with the received viewing history information table. The comparison process is performed by determining whether the information of the title item in the two tables matches. The comparison result is temporarily stored in the storage unit 12 of the communication terminal 1 as a viewing history comparison information table.

  FIG. 15 is a specific example of a viewing history comparison information table that is a result of comparing viewing history information tables acquired from a plurality of communication terminals. The viewing history comparison information table includes a person identifier, a viewing title match rate, and the latest title among viewing title matches. The person identifier is a person identifier of a communication destination user.

The viewing title match rate is a value calculated using the title viewed by the user A1 as a denominator and the number of matches between the titles viewed by the user A1 and the communication destination user as a numerator. The item “latest title among viewing title matches” is the title with the latest viewing date among the titles viewed by the user A1 and the titles viewed by the user of the communication destination.
The communication terminal 1 displays the person names in the phone book information table on the display unit 14 in descending order of the viewing title match rate according to the viewing history comparison information table.

FIG. 16 is a specific example of a phone book information display screen using a viewing history comparison information table. The display screen displays a person name, viewing title match rate, and recently viewed content.
The user A1 performs a call operation by designating a person name displayed on the display unit 14 using the operation input unit 13 of the communication terminal 1.
Through the above procedure, a person who matches the user's preference for video content can be easily found from the telephone directory information, and conversations can be made on the topic of video content that has been viewed recently.

  The present invention can be used for a communication terminal, a communication method, and a program.
