     1. Field of the Invention 
     The present invention is related to an IP communication apparatus that is utilized in a telephone voice/moving picture recording system. 
     2. Description of the Related Art 
     Very recently, the VoIP (Voice over IP) has been rapidly popularized as extension systems of enterprises. While characteristics of IP telephones are effectively utilized, various sorts of conference systems have been conducted to enterprises. Among these conference systems, rapid development may be expected in television conference systems in the near future. Generally speaking, recording of proceedings and reproducing of the recorded proceedings are regularly carried out not only in usual conferences, but also in television conferences, Web conferences, voice conferences, and the like. To this end, such a technical idea that contents of television conferences and voice conferences are stored in the form of voice and moving pictures so as to constitute proceedings records has been proposed (refer to patent publication 1).

It should be understood that in  FIG. 3 , the same reference numerals have been given to structural elements which are commonly used in  FIG. 1  and  FIG. 2 , and therefore, descriptions of the structural elements which are commonly used in  FIG. 1  and  FIG. 2  will be omitted. 
     The operation unit  303  is employed in order that a user of the IP communication apparatus  101  selects saving of any one, or both voice data and moving picture data. The voice present/absent judging unit  201  contained in the signal judging unit  104  judges both voice data inputted from the microphone I/F  301 , and voice data received from the IP packet transmitting/receiving I/F  102 . In such a case that the signal judging unit  104  judges that voice is present in the voice data judged by the voice present/absent judging unit  201 , the judged voice data is furthermore entered to the repetition judging unit  203  in order that the repetition judging unit  203  judges whether or not the judged voice corresponds to repetition speech. The signal judging unit  104  instructs the recording control unit  106  to record only such a voice data which contains the voice and constitutes the repetition source, but not to record voice repetition portions subsequent to the repetition source. Also, the image motion judging unit  202  contained in the signal judging unit  104  judges both moving picture data inputted from the camera I/F  302 , and moving picture data received from the I/P packet transmitting/receiving I/F  102 . In such a case that the signal judging unit  104  judges that a motion is present within the moving picture judged by the image motion judging unit  202 , the judged moving picture data is furthermore entered to the repetition judging unit  203  in order that the repetition judging unit  203  judges whether or not the judged moving picture corresponds to a repetition operation. The signal judging unit  104  instructs the recording control unit  106  to record only such a motion picture data which constitutes the motion and the repetition source, but not record moving picture repetition portions subsequent to the repetition source. 
     The speech recognizing unit  304  recognizes voice data and converts the recognized voice data to character information. The converted character information is recorded in the recording unit  105  by the recording control unit  106 . The personal edge detecting unit  305  detects a boundary between a person and a background from moving picture data. With respect to the above-described moving picture data, the data about the background portion except for the person is overwritten with respect to dummy data, and the overwritten data is recorded in the recording unit  105  by the recording control unit  106 . The time instant acquiring unit  306  contained in the recording control unit  106  acquires such a time instant information when the voice data and the moving picture data are recorded in the recording unit  105 . 
     In accordance with the first embodiment mode, both the voice data and the moving picture data of the repetition portions are not recorded, but the data as to the background portion other than the person is overwritten by the dummy data. As a consequence, an amount of data to be recorded in the recording unit  105  can be furthermore reduced. Also, when the recorded data is reproduced, the speaker can be readily specified in a visual manner. Moreover, the character information is recorded in correspondence with the name of base (IP address) where the speakers participate in the IP telephone conference, the information as to the names of speakers and the recording time instants, and the voice data and the moving picture data while the proceedings are reproduced are recorded. As a result, when the recorded data are reproduced, the contents of the speakers can be readily understood in the visual manner.
