The sound collected by the microphone 5 is processed by the sound processing unit 6 and recorded in the recording memory 7.

  The operation notification sound creating unit 8 creates a sound for notifying the outside of the client portable terminal 100 that the user has performed an image photographing operation or a sound recording operation. For example, it is a shutter sound in the case of an image shooting operation, and some operation sound in the case of a voice recording operation, and a different notification sound is created depending on the operation content. The speaker 9 notifies the outside.

  The short-range wireless communication unit 10 has a function of any one of Bluetooth (R) communication, wireless LAN, and other short-range wireless communication. The antenna 11 transmits and receives radio waves for near field communication.

  The connection request unit 12 causes the operation notification sound generation unit 8 and the speaker 9 to notify the outside as a notification sound such as a shutter sound or a recording operation sound when an image photographing operation or a voice recording operation is performed by the user. This is to notify the user who has performed the operation, and also to the server portable terminal 200 (particularly in connection with the present invention) as a notification sound.

This notification sound is a sound in which the pattern of the notification sound is defined in advance as a notification sound between the client portable terminal 100 and the server portable terminal 200, and the client portable terminal 100 makes a response to the server portable terminal 200. Thus, a connection request for short-range wireless communication is made with this notification sound. In addition, the connection request unit 12 increases the transmission radio wave intensity of the short-range wireless communication unit 10 and the antenna 11 in accordance with the notification timing to the outside.
The content receiving unit 13 processes the content transmitted from the server portable terminal 200 and received by the short-range wireless communication unit 10.

  On the other hand, the server portable terminal 200 that supplies content includes an image file 21, a display unit 22, an audio file 23, an audio processing unit 24, a speaker 25, a microphone 26, a notification sound recognition unit 27, a short-range wireless communication unit 28, and an antenna 29. The connection response unit 30, the content transmission unit 31, and the like.

  The image file 21 stores contents such as still images and moving images including sound. The display unit 22 displays these images and other images. The audio file 23 stores contents such as music and other audio. The audio processing unit 24 processes it and outputs it from the speaker 25 to the outside.

  The microphone 26 collects ambient sounds. The notification sound recognition unit 27 recognizes whether the notification sound has a pattern defined in the specification. The technique for recognizing a specific pattern of notification sound is described in detail in, for example, paragraph numbers [0021 to 0022] and [0029] of JP-A-2005-196539, and details thereof are omitted in the embodiment of the present invention. .

  The near field communication unit 28 has a function of any one of Bluetooth (R) communication, wireless LAN, and other near field communication. The antenna 29 transmits and receives radio waves for near field communication.

  The connection response unit 30 recognizes the case where the notification sound is recognized and the received radio wave strength of the short-range wireless communication unit 28 is high as a connection request from the client portable terminal 100 and connects with the short-range wireless communication unit 28. Returns a response and establishes a connection. Then, the content transmission unit 31 transmits the content using the short-range wireless communication unit 28.

Next, the content management sequence 1 will be described in detail.
FIG. 2 is a diagram for explaining the sequence 1 of the content management system according to the first embodiment of the present invention, and shows the flowcharts of the client portable terminal 100 and the server portable terminal 200 in comparison. The client portable terminal 100 mainly shows processes such as the connection request unit 12 and the content reception unit 13 collectively. The server portable terminal 200 mainly shows processes such as the connection response unit 30 and the content transmission unit 31 collectively.

  When the user's photographing operation such as pressing the shutter button is detected (YES in step S1), the connection request unit 12 of the client portable terminal 100 notifies the shutter sound of a predetermined specification to the outside (step S2). And the arbitrary image image | photographed with imaging | photography operation is memorize | stored in a video recording memory. This is an original image storage process associated with photographing (step S3). The shutter sound with a predetermined specification is a connection request to the server portable terminal 200. In addition, the connection request unit 12 increases the transmission radio wave strength of the short-range wireless communication of the short-range wireless communication unit 10 (step S4). This is also a connection request to the server portable terminal 200.

  On the other hand, the notification sound recognition unit 27 of the server portable terminal 200 recognizes that the sound data collected by the microphone 26 and processed by the sound processing unit 24 is a shutter sound of a predetermined specification (step In step S21, the connection response unit 30 is notified. The connection response unit 30 checks whether or not the radio field intensity received by the short-range wireless communication unit 28 at this time is exceptionally high (step S22). If YES, the connection response unit 30 sends a short-range wireless communication connection response to the client portable terminal 100 by the short-range wireless communication unit 28, and a connection is established between the two (steps S23 and S5).

  Next, the content transmitting unit 31 of the server portable terminal 200 reads out from the corresponding image file or audio file based on the information indicating the content notified from the display unit or the speaker when the shutter sound is recognized in step S21. Then, the short-range wireless communication unit 28 transmits the short-range wireless communication to the client portable terminal 100 (step S24).

  The content receiving unit 13 of the client portable terminal 100 receives the content of the image file via the short-range wireless communication unit 10 (step S6), discards the captured image in the recording memory in S3, and replaces it with the received content. . This is because the user's shooting operation in step S1 is not intended for original shooting but is used as a trigger for obtaining content.

  According to the sequence 1 of the first embodiment of the present invention, the user A of the client portable terminal 100 owns the user B in the situation where the client portable terminal 100 and the server portable terminal 200 are close to each other like face-to-face. The user A of the client portable terminal 100 performs a shooting operation such as pressing the shutter button when he / she wants to easily obtain the image content by viewing the image on the display screen of the server portable terminal 200. At this time, the image captured by the user A with the camera may be anything.

  The client portable terminal 100 can make a connection request using this shooting operation as a trigger. Since the server portable terminal 200 performs simple recognition confirmation whether the radio wave intensity is exceptionally high, it is possible to prevent erroneous connection establishment with other client portable terminals. In addition, the user A of the client portable terminal 100 stores the content received from the server portable terminal 200 in a recording memory in which an image originally captured by the shooting operation is stored without performing operations such as where to store the content. be able to.

  FIG. 3 is a diagram illustrating sequence 2 of the content management system according to the first embodiment of the present invention. In sequence 2, other recognition confirmation is performed instead of recognition confirmation that the radio wave intensity is exceptionally high as in sequence 1. Steps different from FIG. 2 are suffixed with step numbers, and the differences will be mainly described.

  The client portable terminal 100 includes a plurality of types of shutter sounds having a predetermined specification. When the photographing operation is detected (YES in step S1), the connection request unit 12 notifies one of a plurality of types of shutter sounds to the outside (step S2a). Then, after a predetermined time corresponding to the type of shutter sound, the connection request unit 12 transmits a content request signal by the short-range wireless communication of the short-range wireless communication unit 10 (step S4a).

  On the other hand, the notification sound recognition unit 27 of the server portable terminal 200 recognizes that the sound data collected by the microphone 26 and processed by the sound processing unit 24 is one of shutter sounds having a predetermined specification. (YES in step S21a), the connection response unit 30 is notified. The connection response unit 30 waits for a predetermined time corresponding to the type of shutter sound, and then checks whether a content request signal is sent near that timing (step S22a). That is, a time window is provided to check before and after a predetermined time, and it is checked whether the content request signal rises within the time window. If it is within the time window (YES in step S22a), the client portable terminal 100 In response, the short-range wireless communication unit 28 sends a connection response for short-range wireless communication, and the connection is established between the two (steps S23 and S5).

  According to the sequence 2 of the first embodiment of the present invention, simple recognition confirmation can be performed by a method different from that in FIG. 2, and erroneous connection establishment with other client portable terminals can be prevented.

In addition, in common with FIGS. 2 and 3, the following processing may be performed.
The server portable terminal 200 outputs not only the image content displayed on the display unit when the shutter sound is recognized in step S21 or S21a, but also the audio content such as music notified from the speaker when the shutter sound is recognized as an audio file. May be read out and transmitted to the client portable terminal 100.

Further, although the client mobile terminal 100 uses only the shutter sound accompanying the shooting operation as a trigger, it may generate a recording operation sound accompanying the voice recording operation and use it as a trigger.
Further, the server portable terminal 200 recognizes the shutter sound and the recording operation sound separately. When the shutter sound is recognized, the server portable terminal 200 transmits the image content displayed on the display unit. You may make it transmit audio | voice contents, such as the music which was alert | reported. That is, the type of content to be transmitted may be selected according to the type of operation sound.

In the case of a recording operation sound, the received content may be stored in an audio memory in which audio that is originally recorded by the recording operation is stored.
Further, not only sounds such as shutter sounds and recording operation sounds, but also notifications may be made by means of light or magnetism that propagates in the air in accordance with user operations.

  FIG. 4 is a system diagram of content management according to the second embodiment of the present invention. A display unit 14 is added to the first embodiment. The content management system includes a client portable terminal 100 and a server portable terminal 200.
