  In the above description, the information related to the communication partner to be acquired is personal information for uniquely identifying the communication partner, but other information such as preference information may be included. It may also be environmental information such as position information and time information.

  Furthermore, when other person information (personal information) is used in addition to the information for uniquely identifying the communication partner, the searched information can be further narrowed down in the search for the stored information.

  As personal information, instead of using information that uniquely identifies a communication partner, when using preference information or the like, the information may be searched without being limited to information related to the communication partner.

  Here, the communication partner information acquisition process (step S400) will be described in more detail.

  In the communication partner information acquisition process, the communication partner information to be acquired can acquire arbitrary information such as personal information and environment information of the communication partner. A method for specifying information to be described will be described.

  As one of the methods, the communication terminal 201 makes a request for acquiring communication partner information determined in advance. In this case, as an example, the telephone number of the communication partner terminal is used as information for uniquely identifying the communication partner. Request.

  Further, the request information may be selected using a list menu or the like.

  The communication terminal 600 shown in FIG. 6 is provided with a key information selection unit 608 for selecting request information.

  For example, it may be configured such that whether personal information is requested, whether environmental information is requested, or whether both are requested can be selected on a list menu presented from the key information selection unit 608.

  Another method is to request the target information by specifying a target (part of the video) from a pointing device such as a cursor for the video of the communication partner displayed on the display. is there. In other words, when the person video is designated by the cursor, the person information is requested, and when the background is designated, the environment information such as the position information is requested.

  Although the communication terminal 201 requests communication partner information and receives the communication partner information as a response to the request, the communication terminal 202 is configured to notify the communication partner information without making a request. You may do it.

  In addition, when the communication terminal on the receiving side uses information on the communication partner, a caller ID notification obtained in communication connection processing may be used as the communication partner information.

  The calling communication terminal may be configured to search stored information stored in the information storage unit 103 of the calling communication terminal using the calling telephone number as key information.

  Further, the communication terminal may be configured to refer to and use further personal information related to the communication partner based on user information associated with information uniquely identifying the communication partner stored in the information storage unit 103.

  The personal information (personal information) of the communication partner includes information such as date of birth, sex, wedding calendar, occupation, current address, hobby, and preferences, and these can be used as search key information (search conditions).

  Therefore, psychographic information such as hobbies and preferences, demographic information such as age and family structure can be used as search key information.

  In the first embodiment, the telephone number is used as the person information to uniquely identify the communication partner. However, the information for uniquely identifying the communication partner does not have to be a telephone number. You may make it utilize the user identifier provided based on the rule. Also, a user name or e-mail address information registered in the address information may be used.

  Further, in the first embodiment, the example in which person information is used as communication partner information (key information) has been described. However, not only person information but also environment information such as position information and time information may be used. good.

  Next, an example in which position information is acquired from a communication partner terminal as information related to the communication partner will be described.

  In the communication partner information request in step S <b> 304 of FIG. 3, the communication terminal 201 requests location information of the communication terminal 202.

  The communication terminal 202 requested for position information obtains position information by a position measurement function such as a GPS function.

  In transmitting the communication partner information in step S <b> 305, the communication terminal 202 transmits position information to the communication terminal 201.

  Then, the communication terminal 201 obtains position information of the communication terminal 202 that is a communication partner.

  The communication terminal 201 searches the stored information of the communication terminal 201 using the acquired position information of the communication partner as search key information. By this search, the communication terminal 201 gives priority to the storage information related to the position information of the communication partner. Extracted and presented to the user.

  The stored information may be searched using information that uniquely identifies the communication partner, and further narrowed down using position information that is environment information.

  In addition, the GPS function can be used to acquire the position information. However, the position measurement function may not be the GPS function, and it is sufficient if the position information can be acquired. For example, the position information may be acquired by a cellular network.

  Note that the position information may not be latitude / longitude information, but may be information regarding the position. For example, a zip code, address information, area information, landmark information, or the like may be used.

  Further, based on the obtained latitude / longitude information, it may be converted into another format of position information using a database related to the position information. For example, it may be converted into area information and landmark information based on latitude / longitude information.

  The conversion to the position information in another format may be performed on the side requesting the position information, or may be performed on the side requesting the position information.

  Further, the position information request may be made by designating which type of position information is good by the position information requesting side. In this case, the communication terminal that has requested the position information in the designated format converts it into appropriate position information and responds.

  In the search for stored information, as the search information, not only the position information regarding the communication partner but also the position information regarding the own terminal may be used, or both position information may be used together. The use of both pieces of location information means that information between two points is used as search information, that is, information related to two points is preferentially searched, for example, information about a store between two points. Search with priority.

  Furthermore, other environment information such as time information may be acquired together with the position information, and by combining it with the search key information, it becomes possible to acquire information according to the situation of the other party. .

  In the above description, the case where one piece of information (searched information) is extracted is shown, but there may be a plurality of pieces of extracted information. If there is a plurality of related information, it is presented to the user by a preset method.

  When only one piece of information is displayed from a plurality of searched pieces of target information, one method is preferentially selected in the order of shooting time.

  In addition, in order to display a plurality of searched target information, sequential switching display at a certain time interval or simultaneous display of a plurality of information may be performed. For example, the display is as shown in FIGS.

  8 and 9, reference numerals 801 and 901 are counterpart images during communication, and reference numerals 802 and 902 are a plurality of images extracted as a result of search.

  If the extracted saved information is a high-quality still image or moving image, a plurality of information is displayed by a method with a small display load and display area such as a thumbnail so that the user can select it. May be.

  In the case of a moving image, the most relevant frame or scene may be displayed based on the associated attribute information.

  Further, when a plurality of pieces of extracted information are displayed at the same time or when the user can select them, they can be arranged on the time axis.

  In the first embodiment, the telephone number is information that uniquely identifies the user who uses the communication terminal. However, a name and a user identifier may be separately assigned instead of the telephone number. In this case, it is possible to cope with a user having a plurality of telephone numbers.

  In the first embodiment, the system configuration is based on the base station and the communication network. However, the communication terminals may communicate directly with each other using the local communication interface.

  In the first embodiment, an example in which one user is used as a communication partner has been described. However, a multicall for a plurality of communication partners may be used. At that time, it is possible to use group information, hobby information, a common action schedule based on schedule information, and the like, which are information common to a plurality of users, as search key information.

(Embodiment 2)
In the first embodiment, the information for specifying the communication partner is obtained in step S404 in FIG. 4. However, in the second embodiment, the communication terminal 201 obtains the environment information from the communication terminal 202 and searches for stored information. An example where the key information (search condition) is obtained will be described.

  Specifically, it is information that uniquely identifies a communication partner that is personal information, and time information that is environmental information is used as key information for search.

  When the time information is used as key information (search condition) for search, for example, if the communication date is February 16, information related to the past February 16 is preferentially searched.

  Now, in the information storage unit 103 of the communication terminal 201, image information having the photographed date / time information as attribute information is stored. Shooting date and time information is, for example, the date and time when recording was performed during a videophone call, or the date and time when shooting was performed with a camera.

  In addition, the information storage unit 103 of the communication terminal 201 stores address information and schedule information.

  As described in the first embodiment, the communication terminal 201 makes a videophone connection request to the communication terminal 202, becomes in videophone communication, and displays an image of the communication partner.

  The communication partner information acquisition unit 104 of the communication terminal 201 acquires information for uniquely specifying the user B who is the communication partner.

  In the second embodiment, the user B is selected from the address information to make a videophone connection. Therefore, information that uniquely characterizes the communication partner is obtained from the address information. That is, the user B who is the communication partner is uniquely specified using the telephone number obtained from the address information.

  Furthermore, the communication partner information acquisition unit 104 acquires current time information (date / time information) as key information from a clock / calendar function (not shown).

  The stored information search unit 105 of the communication terminal 201 extracts information related to the user B who is the communication partner based on the telephone number which is information for uniquely specifying the communication partner. The information related to the current date and time is preferentially selected from the extracted information related to the user B. Specifically, if there is information corresponding to today's date (February 16), the information corresponding to that date is selected with priority.

  Then, the information reproduction processing unit 106 of the communication terminal 201 causes the output unit 107 to display information related to the extracted user B who is the communication partner.

  The stored information to be searched is important information related to today's date, for example, the birthday of the communication partner. In addition, if the schedule information includes information such as having acted with the communication partner on today's date (February 16) as past information, it is also possible to present information to that effect. . In addition, if information on the place where the user has acted is stored in the schedule information, it is also possible to present information to that effect by performing a search based on the location information of the communication partner. If the schedule information to be stored includes a schedule with the user B as a schedule for today, it may be displayed.

  Further, time information may be acquired from a communication partner, and the acquired time information may be used as search key information, which is effective for a communication partner having a time difference. For example, if the current time related to the communication terminal of the communication partner is 21:00 and indicates the night time zone, the search is performed with priority on the data on the night, that is, the information on the time of the communication partner. To do.

  As described above, according to the second embodiment, the communication terminal 201 searches and displays the stored information in the communication terminal 201 using the environment information acquired from the communication terminal 202 as the communication partner as key information. By automatically displaying information that the communication partner is interested in, it is possible to support more active communication, and even for elderly people who are unfamiliar with the operation of information equipment by simplifying the operation. , You can easily talk while displaying various video information, and you can promote warm communication.

  In the second embodiment, the date information is used as the time information. However, the time information may be other information such as time information, date / time information, day information, month information, time zone information decided in advance, and the like. Any information about time may be used.

  Further, the searched information (searched information) may be mail information transmitted / received in the past. In this case, for example, e-mail information sent from a person in communication is searched.

(Embodiment 3)
Embodiment 3 is a communication terminal in which information related to a communication partner is obtained by recognizing information received from the communication partner, and the recognition information is used as search key information.

  In the third embodiment, a communication method for searching and presenting stored information based on recognition information obtained by sound recognition will be described with reference to FIG.

  The information storage unit 103 of the communication terminal 201 stores both image information and person characteristic information related to the image information. Further, it is assumed that the feature information of the person includes the feature information about the voice, and the communication terminal 202 is configured to send the key information to the communication terminal 201 in response to the key information acquisition request of the communication terminal 201. ing.

  When the communication terminal 201 makes a connection request by videophone to the communication terminal 202 and receives an acceptance response from the communication terminal 202, the communication terminal 201 Videophone communication is performed by the 3G-324M protocol using 223 multiplexing (step S1001).

  The video is transmitted and received using the video channel, and the other party's video is displayed by the output unit 107 (step S1002). It also has a conversation through the audio channel.

  The communication partner information acquisition unit 104 of the communication terminal 201 extracts the other party's voice information in the conversation using the audio channel (step S1003). Further, the communication partner information acquisition unit 104 further extracts the other party's voice information. The communication partner is uniquely identified by performing analysis and referring to the voice database storing the voice characteristics stored in the information storage unit 103 (step S1004).

  The stored information search unit 105 of the communication terminal 201 searches the stored information stored in the information storage unit 103 based on the specified communication partner information, and extracts information related to the user B who is the communication partner (step S1005).

  The information reproduction processing unit 106 of the communication terminal 201 displays the image information, which is information related to the extracted user B, via the output unit 107 (step S1006).

  Of course, these steps are performed automatically in succession.

  Thus, according to the third embodiment, the communication terminal 201 searches and displays the stored information in the communication terminal 201 using the voice information acquired from the communication terminal 202 that is the communication partner as key information. By automatically displaying information that the communication partner is interested in, it is possible to support more active communication, and even for elderly people who are unfamiliar with the operation of information equipment by simplifying the operation. , You can easily talk while displaying various video information, and you can promote warm communication.

  Note that a user interface for controlling the timing for performing voice recognition may be provided.

  For example, in order to control the timing for performing voice recognition, software keys and / or hardware keys are provided, and voice recognition is performed using a predetermined key press as a trigger.

  The timing for performing voice recognition may be performed at any time determined in advance during communication.

  When voice recognition is performed as needed, even when the target user (user using the terminal) changes in the communication partner terminal, the user can quickly identify the user as the communication partner without any operation.

  Note that the use of voice recognition not only uniquely identifies a communication partner, but also may be used to obtain a keyword for searching. In this way, stored information can be searched based on the words spoken by the communication partner, and information related to the conversation can be easily extracted.

  The communication terminal can improve speech recognition by storing a term database that assists speech recognition.

  Note that the voice recognition may be performed not only for the communication partner but also for the user of the terminal itself.

  Further, the sound information to be recognized is not limited to the sound information but may be an environmental sound. For example, by recognizing the environmental sound, it is possible to obtain information such as what kind of place the communication partner is in and what situation. For example, it is possible to distinguish between indoors, outdoors, and traveling in a car, and information corresponding to them can be searched. In addition, by recognizing that it is a specific place, for example, a concert venue or a station where a sound related to a train can be heard, it becomes possible to extract information according to the environment of the communication partner. . For example, if you are in a place where you can hear the sound of a waterfall, it is possible to preferentially extract the stored information related to the waterfall. If the user is at a station, the timetable information can be preferentially extracted. The extracted timetable information can be transmitted to a communication partner terminal and displayed. With this configuration, it is possible to easily extract and provide information necessary for the communication partner.

  In the above description, the communication partner is uniquely identified by the voice information. However, the communication partner may be identified including the emotion of the communication partner. By doing in this way, it becomes possible to extract the preservation | save information according to the communication partner's emotion.

  In the third embodiment, the example in which the sound information is recognized and the information related to the communication partner is acquired has been described. However, the information to be recognized may be video information received from the communication partner. By analyzing the video information displayed by the communication partner using image recognition means, the person's feature information is extracted, and the person's feature information included in the user information is referenced to uniquely identify the communication partner. It becomes possible to do.

  In the above description, the information on the person of the communication partner is used as the search key information. However, the present invention is not limited to this, and information such as landscape information captured by the communication partner terminal may be used. For example, in the case of a building, related information can be searched using the feature information of the building as search information.

  Alternatively, the pointing device may be used to recognize the image with priority given to the image information of the indicated portion. With this configuration, it is possible to recognize an image by designating a recognition target. For example, if a plurality of persons or both a person and a building are displayed as an image, it can be designated as search key information by pointing one of them with a pointer device.

  If attribute information associated with a video object is received together, the attribute information can be used as search information. The attribute information is, for example, a person name or a building name attached to the image information as description information. Furthermore, it is also possible to use attribute information related to a target pointed by the pointing device as search information.

  Further, auxiliary designation may be prompted to narrow down the search. For example, it is designated whether information related to the position is prioritized or information related to time is prioritized.

(Embodiment 4)
The fourth embodiment will be described with reference to FIGS.

  Embodiment 4 is a communication method in which information extracted using communication partner information is shared and displayed by communication terminal 202 in communication terminal 201, and this communication method will be described with reference to FIG. I will explain.

  Also in the fourth embodiment, with respect to the videophone communication, similarly to the first embodiment, communication is performed using the 3G-324M protocol.

  The communication terminal 201 makes a videophone connection request to the communication terminal 202 (step S1101).

  The communication terminal 202 makes a connection permission response (step S1102).

  A session for making a videophone call is established and videophone communication is in progress (step S1103).

  As described in the first embodiment, the communication terminal 201 obtains information that uniquely identifies the user B who is the communication partner, and based on the information that uniquely identifies the user B, information related to the user B is obtained. Extracted from the information storage unit 103 of the communication terminal 201. Then, the communication terminal 201 transmits a confirmation request for the reproduction capability information of the extracted image to the communication terminal 202 via the data transmission channel (step S1104).

  Here, the following steps will be described by taking as an example the case where the resolution information included in the still image reproduction capability is used as the reproduction capability information.

  The communication terminal 202 extracts information related to the reproduction capability requested to be confirmed, and transmits information reproduction capability information to the communication terminal 201 (step S1105).

  The communication terminal 201 refers to the acquired reproduction capability information related to the communication terminal 202, converts the still image that is the search target information into a format that can be reproduced by the communication terminal 202, if necessary, and sends it to the communication terminal 202. On the other hand, it transmits via a data transmission channel (step S1106).

  At this time, both the communication terminal 201 and the communication terminal 202 display a still image that is information to be searched.

  FIG. 12 is a block diagram of communication terminal 1200 according to Embodiment 4, and this communication terminal 1200 includes an image conversion unit 1208 for performing the image conversion process executed in step S1106.

  Here, conversion to a format reproducible by the communication terminal 202 will be described.

  Specifically, the communication terminal 201 confirms the image reproduction capability of the communication terminal 202 of the communication partner when image data stored in the CIF (Common Interface Format) format is extracted. Assume that 202 has reproduction capability up to the QCIF (Quarter CIF) format. In this case, since the communication terminal 202 cannot be played back in the CIF format stored in the communication terminal 201, the communication terminal 201 converts the data into QCIF format data that can be played back by the communication terminal 202, and transmits the data to the communication partner terminal 202. (Step S1106).

  In this case, the communication terminal 201 displays the image as a QCIF format image in accordance with the communication partner, but may display the image data as a CIF format image that is the original storage format.

  As described above, according to the fourth embodiment, communication terminal 201 searches for and displays stored information in communication terminal 201 using communication partner information acquired from communication terminal 202 as a communication partner as key information. Because the information is shared between the communication terminal 201 and the communication terminal 202, it is possible to support the activation of communication more easily, and the operation is simplified, even for an elderly person who is unfamiliar with the operation of the information device. You can make a call while displaying various video information on the screen, and you can promote warm communication.

  In the above description, the example using the resolution is shown as the reproduction capability information of the still image. However, the information may not be the resolution and may be information regarding the reproduction capability such as the display color.

  In the above description, an example of still image reproduction capability information is shown as the reproduction capability information. However, information regarding a moving image may be used.

  The playback capability information may not be playback capability information related to images, but may be playback capability information related to sound and playback capability information related to structured data such as XML (Extensible Markup Language).

  In the above description, the stored information is converted according to the reproduction capability information of the communication partner. However, the stored information may be converted according to the communication state between the terminals. For example, when the transmission capacity for data transmission cannot be increased, the data is converted and transmitted so that the data size is reduced. For example, video data may be compressed and transmitted as a JPEG still image.

  In the stored information search process, the search may be performed using the reproduction ability information of the communication partner as a search condition.
