Description

The present invention is a mobile communication terminal for outputting the music data, and, regarding the program.

  In mobile communication such as a mobile phone, it is widely performed that a music is used as a ringtone when an incoming call is received (hereinafter referred to as “musical ringtone”). Music data used for such music ringtones is generally distributed to mobile communication terminals via the Internet or the like. Recently, music containing singing voices by singers and the like are also distributed as music ringtones.

  Conventionally, music data to be distributed is generally only a part of music (for example, a characteristic part of music, so-called “rust”). For this reason, even if the user desires to use a part other than the delivered music part as a ring tone, only the delivered music part can be used as a ring tone.

  On the other hand, a technique has also been realized in which music data recorded on a recording medium such as a CD (Compact Disc) is taken into a mobile communication terminal and used as a ring tone. In such a form, there has also been proposed a method in which a user-desired portion can be used as a ring tone by editing sound source data to be captured (for example, Patent Document 1).

However, in the method disclosed in Patent Document 1, it is necessary to work using a device other than the mobile communication terminal. In addition, it is necessary to prepare a recording medium as a sound source, and the user's work is complicated.

The external configuration of the mobile communication terminal 100 includes an antenna 121, a microphone 131, an operation unit 132, a speaker 141, a display unit 143, and the like as shown in FIG. The mobile communication terminal 100 is a mobile communication terminal device (telephone) such as a mobile phone or a PHS (Personal Handyphone System), and performs, for example, digital communication. The mobile communication terminal 100 according to the present embodiment can acquire music data such as music and output it as a ringtone (hereinafter referred to as “music ringtone”). The configuration of such mobile communication terminal 100 will be described with reference to FIG.

  FIG. 2 is a block diagram showing a configuration when the mobile communication terminal 100 is a mobile phone. As illustrated, the mobile communication terminal 100 includes a control unit 110, an antenna 121, a data communication unit 122, a reception unit 123, a transmission unit 124, a microphone 131, an operation unit 132, speakers 141 and 142, a display unit 143, and screen generation. Unit 144, audio data processing unit 161, D / A 162, A / D 171, encoding unit 172, ringtone control unit 180, storage unit 190, and the like.

  The control unit 110 includes, for example, a CPU (Central Processing Unit) and controls each unit of the mobile communication terminal 100.

  The antenna 121, the data communication unit 122, the reception unit 123, and the transmission unit 124 are configurations for realizing the communication operation of the mobile communication terminal 100. The data communication unit 122 performs data communication with other devices via, for example, the Internet. The reception unit 123 and the transmission unit 124 perform a voice call with other telephones via the mobile communication network. Information transmitted and received by data communication and voice call is input / output via the antenna 121.

  The microphone 131 inputs a user's uttered voice during a voice call. The operation unit 132 includes, for example, a cross cursor key, alphanumeric keys for inputting numbers and characters, buttons for designating functions, and the like, and is operated by the user of the mobile communication terminal 100. The operation analysis unit 133 recognizes an operation performed by the operation unit 132 and inputs the operation to the control unit 110. In the present embodiment, buttons (selection fields) displayed as images on the screen of the display unit 143 and physical keys constituting the operation unit 132 are interlocked at any time, so that each key of the operation unit 132 is linked. Assign multiple functions to. Therefore, it is assumed that the operation analysis unit 133 recognizes that the operation of the operation unit 132 and the image displayed on the screen are associated with each other and inputs them to the control unit 110.

  The speaker 141 outputs an incoming voice in a voice call, and the speaker 142 outputs a voice such as a ringtone.

  The display unit 143 includes, for example, a liquid crystal display (LCD) and displays an image or the like for executing various operations by the mobile communication terminal 100. The screen generation unit 144 generates an image to be displayed on the display unit 143.

  The voice data processing unit 161 acquires the incoming voice information at the time of voice call from the receiving unit 123 and decodes it. A D / A (digital-analog converter) 162 converts the decoded digital audio data into an analog audio signal and outputs the analog audio signal from the speaker 141.

  An A / D (analog-to-digital converter) 171 converts a speech voice input from the microphone 131 during a voice call into digital data. The encoding unit 172 encodes (encodes) the converted digital data and sends the encoded digital data to the transmission unit 124.

  The ring tone control unit 180 performs processing related to a ring tone that is output when the mobile communication terminal 100 receives a call. The ring tone control unit 180 includes a music editing unit 181, a playback unit 182, and a D / A 183.

  The music editing unit 181 controls the interface for the user to edit the music data indicating the music, and enables the user to edit. In the present embodiment, an image for editing music is generated and displayed on the display unit 143 in cooperation with the control unit 110 and the image generation unit 144.

  The playback unit 182 plays back the music data stored in the storage unit 190. Here, the music data (digital data) is decoded and sent to the D / A 183.

  A D / A (digital-analog converter) 183 converts the decoded music data into an analog signal and sends it to the speaker 142. Thereby, the music is reported as a ring tone.

  The storage unit 190 is composed of a storage device such as a ROM or a flash memory, for example, and mainly stores user-specific information (user data). In the present embodiment, music data used as a ringtone is stored. That is, under the control of the ring tone control unit 180, an area for storing data related to the ring tone is created in the storage unit 190.

  In the present embodiment, music data downloaded from a website that provides a music distribution service is stored. In the music data, a file composed of actual data for reproducing the music and additional information is created for each music. Two types of files are prepared: a “full music file” indicating the entire range of music and a “ringtone file” indicating a part of the music. The “ringtone file” is a file that includes music data that the playback unit 182 of the ringtone control unit 180 plays as a ringtone. In addition to the music data edited in advance by the distributor, the ring tone file includes music data edited by the user by editing processing described later in this embodiment.

  Here, the data structure of the “full music file” and the “ring tone file” will be described with reference to FIG.

  FIG. 3A is a diagram illustrating an example of a data configuration in the “full music file”. As shown in the figure, in the “full music file”, each of “attribute information”, “configuration information”, “playback range”, “actual data”, etc. is followed by a “file name” for identifying the file. An area is included.

  In the “attribute information”, information indicating the total playback time of the music is recorded in addition to the name of the music, the artist name indicating the performer or performer, the name of the album in which the music is recorded, and the like.

  In the “configuration information”, song feature information indicating a feature portion (song feature portion) of the song is recorded. Here, the “song feature part” indicates a feature part in the music composition such as “rust”, and is set by the music data distributor. In the “configuration information”, the start position and the end position of each music feature are indicated by the elapsed time when the music is reproduced from the beginning.

  In the present embodiment, for easy understanding, it is assumed that three music feature parts (Cha A, Cabi B, Cabi C) are set for one full music file. Here, for example, a frequently used music feature portion used as a ring tone is set. For example, in the case of music containing a singing voice, the “rust” part is a characteristic part of the music and is frequently used as a ringtone. Therefore, in this embodiment, it is assumed that the music distribution information indicating the rust portion in the music is set in the “configuration information” by the music distribution provider. It should be noted that which music feature part is set and the number of music feature parts that can be set can be arbitrarily set by the music distribution provider.

  In the “playback range”, information indicating a range of the music to be played as a ringtone is recorded. In the present embodiment, the reproduction range is designated by the user editing the distributed full music by an editing process described later. That is, the “reproduction range” stores information indicating a range in the music reproduced as a ringtone when a call is received at the mobile communication terminal 100. Here, the start position and end position of the characteristic portion corresponding to the reproduction range are indicated by the elapsed time when the music is reproduced from the beginning.

  In “actual data”, music data for reproducing the music is recorded. The music data is, for example, data in the SMAF (Synthetic music Mobile Application Format) format. The music data includes information indicating the playback time from the beginning of the music (hereinafter referred to as “playback time information”).

  Next, the data structure of the “ringtone file” will be described with reference to FIG. As shown in the figure, the “ringtone file” includes areas such as “attribute information” and “actual data” following the “file name” for identifying the file.

  As for “attribute information”, the same information as the attribute information in “full music file” is stored. In the “actual data”, music data indicating a part of the music is recorded. The actual data in the ring tone file is, for example, music data for reproducing only the chorus portion of the music. Here, the music data edited by the distributor in advance is recorded, and the music data edited by the user by the editing process described later is recorded.

  In the present embodiment, the “full music file” and the “ringtone file” are stored in different areas (folders). In the present embodiment, a folder in which a full music file is stored is referred to as a “full music folder”, and a folder in which a ringtone file is stored is referred to as a “ringtone folder”.

  Such music data is, for example, a mobile communication provider (that is, a communication carrier) that provides a telephone communication service using the mobile communication terminal 100, an official website approved by the mobile communication provider, or It is assumed that the mobile communication terminal 100 is provided (distributed) by a music distribution service implemented by an unofficial website that is not authorized. In this case, the mobile communication terminal 100 downloads music data from the device that provides each website and distributes music data (hereinafter referred to as “music distribution server”) via the Internet or the like.

  Each music distribution server of each website accumulates music data of various music and provides the music data to the mobile communication terminal 100 through the Internet. In this embodiment, for each music, two types of music files, a full music file and a ringtone file, are prepared in the music distribution server, and any type of music file is selected in response to a request from the mobile communication terminal 100. Select and distribute. The music distribution server stores, for each full music file stored, music characteristic information (configuration information) indicating the characteristics of each music in association with each music, and distributes the full music file. In addition, the music feature information corresponding to the music is distributed together.

  Hereinafter, the “editing process” performed by the mobile communication terminal 100 for editing the music data of the full music downloaded from the website provided by the music distribution server as an incoming call ringtone will be described.

  This editing process enables a user of the mobile communication terminal 100 to use any desired portion of the music data downloaded from the music distribution website as a music ringtone, according to the operation of the operation unit 132. It is assumed that an editing process is instructed from a predetermined menu displayed on the display unit 143 to set the music ringtone as an arbitrary part of the full music.

  First, the procedure for designating the music to be edited, which is performed prior to the editing process, will be described with reference to FIG.

  First, as shown in FIG. 4A, from the menu screen for displaying a list of folders for selecting a folder of various data stored in the storage unit 190, a “full music folder” in which full music files are stored is displayed. ”Is designated by operating the cross cursor key or the alphanumeric key of the operation unit 132 of the mobile phone, all the song names of the full song file stored in the full song folder as shown in FIG. The music selection screen is displayed. When the user designates a desired music piece by operating the cross-shaped cursor key or the alphanumeric key and then designates the “menu” button, as shown in FIG. The menu screen is displayed. Then, among the items displayed on the submenu screen, “edit” for designating editing of the music is designated by operating the cross cursor key or the alphanumeric key, and the editing process is started.

  The “editing process” executed in the mobile communication terminal 100 to edit the music specified in this way will be described with reference to the flowchart shown in FIG.

  When the editing process is started, the music editing unit 181 first acquires the music feature information of the music from the full music file of the designated music (step S101), and each piece of music feature information is shown in FIG. A “default selection screen” in the menu selection format as shown in FIG. 6 is created and displayed on the display unit 143 (step S102).

  Here, on the default selection screen shown in FIG. 9A, three music feature parts (components) shown in the full music file are shown. In the present embodiment, three types of rust A, rust B, and rust C are shown. These are candidates for parts that can be used as default ringtones set by the music distribution site in advance (hereinafter referred to as “default parts”). With such a default selection screen, the user can select a music feature portion that is desired to be included in the ringtone.

  In the default selection screen shown in FIG. 9A, music feature information indicating three default parts (Chain A, Cabi B, Cabi C) is displayed in order for the user to select a desired music characteristic part (component). It is displayed as selectable. In addition, in order to use a portion other than the default portion set by the music distribution site as a ring tone, an item “no reference” for editing without referring to these default portions is also displayed. “No reference” is selected when none of the three default parts is to be included as a ring tone.

  The user operates the cross cursor key or the alphanumeric key of the operation unit 132 to select one of the default parts (Chain A, Cabi B, Cabi C) displayed on the default selection screen shown in FIG. Select the “OK” button. By this operation, information specifying which of the selected default parts is input to the music editing unit 181. In the present embodiment, it is assumed that “rust A” is selected.

  The music editing unit 181 acquires a music feature part indicating the selected default part from the full music file of the music in the storage unit 190. The screen generation unit 144 displays an “edit position designation screen” on the display unit 143 as shown in FIG. 9B, indicating that the start position and end position indicated in the configuration information can be selected (step S103). ). Here, when the range of the chorus A of the selected music is, for example, “0: 40-0: 60”, the items “start position 0:40” and “end position 0:60” can be selected. Is displayed.

  The user operates the cross cursor key or alphanumeric key of the operation unit 132 to select and specify either “start position” or “end position”.

  Here, when the user wants to arbitrarily designate the start position (hereinafter referred to as “start point”) of the range to be used as the ring tone, the item “start position” on the edit position designation screen is selected. When the user wants to arbitrarily specify the final position (hereinafter referred to as “end point”) of the range to be used as the ring tone, the item “end position” on the edit position designation screen is selected.

  When the item “start position” is selected on the edit position designation screen (step S104: Yes), the music editing unit 181 executes “start point setting process” (step S200) for setting an arbitrary start point, When “end position” is selected (step S104: No), “end point setting process” (step S300) for setting an arbitrary end point is executed. The processing contents of each processing procedure will be described below.

  FIG. 6 is a flowchart showing the contents of the “start point setting process” (step S200) performed by the music editing unit 181. Here, since “Cho A” is selected as the desired default portion, processing for designating an arbitrary start point is performed while including the entire range of the chorus A.

  When the start point setting process is started, the music editing unit 181 first acquires the attribute information of the selected music from the storage unit 190. The music editing unit 181 displays the playback time indicated in the acquired attribute information, the start time and end time of the selected default part (Chain A), and the preset maximum playback time and minimum playback of the music ringtone. Based on the time, a start point designation screen BW as shown in FIG. 10A is generated and displayed on the display unit 143 (step S201).

  Here, the maximum reproduction time indicates the maximum time (allowable range) that can be reproduced as a ring tone, and the minimum reproduction time indicates the minimum time (allowable range) that can be reproduced as a ring tone. The maximum playback time is specified in advance by the performance of the mobile communication terminal 100, for example, and is arbitrarily specified by the user, for example. The minimum playback time is set in advance in the mobile communication terminal 100 as a minimum playback time required to function as a ring tone, for example, and is arbitrarily designated by the user, for example. In the present embodiment, the maximum playback time is 45 seconds and the minimum playback time is 5 seconds.

  That is, if the time that can be specified as the ring tone for the specified music is t, the range of “5 seconds ≦ t ≦ 45 seconds” (that is, 40 seconds) is the range (allowable range) that can be specified as the ring tone. Here, since the start time of the chorus A is 0:40 and the end time is 0:60, the reproduction time (Δt) of the chorus A is 20 seconds. Accordingly, the entire range of the chorus A is within the allowable range even if the ring tone is used. In addition, since Δt <t, the start point or the end point can be specified before and after the entire range of the selected default portion (rust A).

  Here, the start point designation screen BW will be described. As shown in FIG. 10 (a), the start point designation screen BW displays the attribute information of the selected music, as well as the position indicator IND1 that serves as a guide for designating the start point, and when the music is played back. The elapsed time is displayed. The position indicator IND1 will be described with reference to FIG.

  The time scale of the position indicator IND1 corresponds to the total playback time of the designated music piece. In this embodiment, in order to facilitate understanding, the total playback time of the designated music is 100 seconds, and the leftmost end of the position indicator IND1 is 00 and the rightmost end is 100. Therefore, the position on the position indicator IND1 corresponds to the elapsed time when the music is played from the beginning.

  As shown in FIG. 10B, on the position indicator IND1, bars B11 to B13 indicating a position to be referred to when editing the full music with reference to the designated default portion, and a cursor C1 are displayed. On the position indicator IND1 when the start point setting process is executed, the cursor C1 is displayed at the selected default portion, that is, the position 40 indicating the start time of the chorus A.

  A bar B11 indicating the end position is displayed at the position (position 60) indicating the end time of the selected default part (rust A).

  Further, at a position where the elapsed time is 15 seconds, a bar B12 indicating the foremost end that is allowed to be specified as the starting point of the ringtone is displayed. Here, since the maximum playback time that can be played back as a ringtone is 45 seconds, a 15-second position (position 15) 45 seconds before the 60-second position indicating the end position of chorus A can be specified as the start point. Displayed as the leading edge position

  Further, at the position where the elapsed time is 95 seconds (position 95), a bar B13 indicating the last end that is allowed to be specified as the start point is displayed. Here, since the minimum playback time that can be played back as a ringtone is 5 seconds, the position that is 5 seconds before the position 100 at the end of the music is displayed as the end position that can be specified as the start point. That is, even after the position indicated by the bar B13, the minimum reproduction time (allowable range) is not satisfied, and therefore it cannot be designated as a ring tone.

  As described above, the music editing unit 181 identifies the temporal position of the designated default part (Chain A) based on the configuration information (music characteristic information), and uses the identified position as a reference such as a cursor or a bar. Display visual information. In addition, these bars indicate a range (allowable range) that can be specified as the starting point. Note that the bars shown on the position indicator may be displayed in different colors, for example. By doing so, the range that can be set as the starting point can be easily recognized.

  Returning to the description of the “start point setting process” shown in FIG. When a predetermined button corresponding to the selection field “play” in the lower area of the start point designation screen BW is operated (step S202: Yes), the playing unit 182 plays the music from the beginning. That is, the music data recorded in the full music file of the music is reproduced. In addition, the music editing unit 181 resets the cursor C1 on the position indicator IND1 to a position corresponding to the head of the music, that is, the position 00, and displays it so as to move on the position indicator IND1 as the music progresses. (Step S203). Here, the cursor C1 moves in the right direction from the left end of the position indicator IND1 as the music is played. The music editing unit 181 also displays the elapsed time at the time of reproduction in units of seconds based on the reproduction time information included in the music data of the music. This elapsed time is displayed as the elapsed time from the beginning of the music.

  On the other hand, when it is determined that the predetermined button corresponding to the selection field “start point” in the lower area on the start point designation screen BW has been operated in the determination process in step S202 described above (step S202: No), The “setting process” is terminated, and the flow returns to the “editing process” flow shown in FIG. In this case, the current position of the cursor C1, that is, the start position of the chorus A is designated as the start point. In this case, since the designated starting point is not the user's arbitrary position, but the same as the default starting point (starting position of chorus A), the “end point setting process” for allowing the user to arbitrarily specify the end point (see FIG. 5: Proceed to step S300).

  When it is determined in the determination processing in step S202 described above that a predetermined button corresponding to the selection field “play” has been operated and the music starts to be played from the beginning, the user is read from the full music file. While listening to the music reproduced by the reproduction unit 182 and output from the speaker 142 via the D / A 183, the selection field “start point” in the lower area on the start point designation screen BW is displayed when the part to be used as a ring tone is reached. Operate the corresponding predetermined button.

  When the button corresponding to the selection field “starting point” is operated (step S204: Yes), the music editing unit 181 operates the button corresponding to the selection field “playing” and then the button corresponding to the selection field “starting point”. Whether the current position of the cursor C1 when the start point is designated is before the end position indicated by the end bar B13, that is, the start point Is determined to be within an allowable range (step S205).

  When it is determined in the determination process in step S205 that the start point is specified after the end position (step S205: No), the position specified as the start point is not within the allowable range. Returning to the process of step S201, the start point designation screen BW is displayed again in order to reset the start point.

  On the other hand, when it is determined in the determination processing in step S205 described above that the start point is specified before the end position (step S205: Yes), the music editing unit 181 determines that the current position of the cursor C1 is It is determined whether or not the position is after the foremost end position indicated by the foremost end bar B12 (step S206).

  When it is determined in the determination processing in step S206 that the specified position is after the frontmost position (step S206: Yes), the music editing unit 181 specifies the specified position as the starting point of the ring tone. At the same time (step S207), the end position of the designated default part (rust A) is designated as the end point (step S208). In this case, the music editing unit 181 accesses the storage unit 190 and records elapsed time information indicating the position designated by the user at the “start point” of the “reproduction range” in the full music file of the music. ”Is recorded the elapsed time information indicating the end position of the chorus A.

  That is, since the default portion desired by the user is chorus A, if the entire range of chorus A can be included as a ring tone, the end position of chorus A is set as the default end point. In this case, a range from a position arbitrarily designated by the user to the end position of the chorus A is reproduced as a ring tone.

  When the end point is designated in step S208, the flow returns to the "editing process" flow shown in FIG.

  On the other hand, if the position designated by the user is in front of the forefront position in the determination process in step S206 (step S206: No), if the position is the starting point, the designated default part (rust A) Will not be able to include all of them. In this case, the music editing unit 181 notifies the user that the entire range of the designated default part (Chain A) cannot be included in the ringtone, and a pop-up window PW1 as shown in FIG. Is displayed on the display unit 143 (step S209).

  As shown in the figure, the pop-up window PW1 displays a message indicating that the default end point, that is, the end position of the chorus A is not set as the end point, because not all of the chorus A can be included in the ringtone at the specified start point. The

  In this case, the music editing unit 181 designates the position designated by the user as the start point of the ring tone, and designates the position 5 seconds after the start point (minimum reproduction time) as the end point (step S210). Here, the music editing unit 181 accesses the storage unit 190 and records elapsed time information indicating the position designated by the user in the “start point” of the “playback range” in the full music file of the music, and this start point. Elapsed time information indicating the position 5 seconds after (minimum playback time) is recorded in the “end point”.

  That is, if the default part desired by the user is chorus A but the entire range of chorus A cannot be included as a ringtone, the end point is set at a position that has passed the minimum playback time from the position specified by the user. Here, the end point is automatically changed. In this case, a range of 5 seconds from a position arbitrarily designated by the user is reproduced as a ring tone.

  Note that the playback time when the entire range of the default part cannot be included is not limited to the minimum playback time and is arbitrary.

  When the end point is designated in step S210, the flow returns to the "editing process" flow shown in FIG.

  Next, the “end point setting process” (step S300) will be described. This end point setting process is performed when “end position” is selected on the editing position designation screen shown in FIG. 9B in the “editing process” shown in FIG. 5 (step S104: No), or “start point setting process” ”(Step S200). This “end point setting process” will be described with reference to the flowchart shown in FIG.

  When the process is started, the music editing unit 181 determines whether or not the reproduction range is not set for the selected music (step S301). That is, when the reproduction range has already been set by executing the start point setting process (step S301: No), the end point has already been set by default, and the process is ended as it is. That is, the flow returns to the “editing process” flow shown in FIG.

  On the other hand, when the reproduction range is not set (step S301: Yes), the music editing unit 181 displays the “reproduction time” of the designated music, the “configuration information” of the selected default part (Chain A), and Based on the preset “maximum reproduction time” and “minimum reproduction time”, an end point designation screen EW as shown in FIG. 11A is generated and displayed on the display unit 143 (step S302).

  Here, on the end point designation screen EW shown in FIG. 11A, a position indicator IND2 serving as a guideline for designating the end point is displayed. The position indicator IND2 will be described with reference to FIG. FIG. 11B is an enlarged view of the position indicator IND2. As with the position indicator IND1 on the start point designation screen BW, the time scale of the position indicator IND2 corresponds to the total playback time of the designated music piece.

  As illustrated, in the position indicator IND2 on the end point designation screen EW, the cursor C2 is displayed at the end position (position 60) of the selected default portion (rust A).

  In addition, a bar B21 indicating the start position is displayed at the start position (position 40) of the selected default portion (rust A).

  A bar B22 indicating the last end that can be specified as the end point is displayed at a position 45 seconds after the start position of the chorus A indicated by the bar B21 (position 85). This indicates the end position that can be specified as the end point when the start position of the chorus A is set as the start point (default start point). That is, when the entire range of chorus A is to be included in the ringtone, the end point is designated at a position before bar B22 (allowable range when the full range of chorus A is included).

  Further, a bar B23 indicating the foremost end that can be specified as the end point is displayed at a position 5 seconds after the beginning of the music (that is, the position of “00”) (that is, the position of “05”). That is, since the minimum playback time is 5 seconds, even if the position from the beginning of the music to 5 seconds later is the end point, the ring tone does not satisfy the minimum playback time (allowable range). Therefore, when specifying the end point, the position after the bar B23 is specified.

  Further, in the lower area of the end point designation screen EW, as shown in FIG. 11A, a selection field “play” for designating the reproduction of the music and a selection field for designating the position to be the end point “End” is displayed.

  Here, when a predetermined button corresponding to the selection field “play” is operated (step S303: Yes), the music editing unit 181 causes the playback unit 182 to play the music from the top. That is, the music data recorded in the full music file of the music is reproduced. In addition, the music editing unit 181 resets the cursor C2 on the position indicator to the position 00 corresponding to the head of the music and displays it so as to move on the position indicator as the music progresses (step S304). That is, the cursor C2 moves to the right from the left end of the position indicator IND2 in accordance with the progress of the reproduced music. Note that the music editing unit 181 displays the elapsed playback time from the beginning of the music as needed.

  When a song is played from the beginning, the user listens to the played song and corresponds to the selection field “end point” when the desired end point position is reached (that is, the rear end position of the range to be used as a ring tone). Operate a predetermined button.

  When a predetermined button corresponding to the selection field “end point” is operated (step S305: Yes), the music editing unit 181 determines that the designated position is based on the elapsed time when the selection field “end point” is selected. , It is determined whether or not it is after the specifiable front end position indicated by the bar B23, that is, whether or not it is within the allowable range (step S306).

  If it is specified before the foremost position (step S306: No), the specified position is not within the allowable range. Here, even if the position is set as the end point, the ringing tone that satisfies the minimum reproduction time cannot be obtained. Therefore, the process returns to step S302, and the end point designation screen EW is displayed again to designate the end point.

  On the other hand, when the designated position is after the frontmost end position (step S306: Yes), the music editing unit 181 further determines that the designated position is higher than the last position that can be designated, which is indicated by the bar B22. It is determined whether it is before, that is, whether it is within an allowable range when the entire range of rust A is included (step S307).

  When the position designated by the user is before the last position (step S307: Yes), the music editing unit 181 designates the start position of the chorus A as the start point (step S308) and is designated by the user. The designated position is designated as the end point (step S309). Here, the music editing unit 181 accesses the storage unit 190, and the elapsed time information indicating the start position of the designated default portion, that is, the chorus A, is displayed at the “start point” of the “reproduction range” in the full music file of the music. And the elapsed time information indicating the position designated by the user is recorded in the “end point”.

  When the end point is designated in step S309, the process ends, and the flow returns to the “editing process” flow shown in FIG. In this case, a range from the start position of the chorus A to a position arbitrarily designated by the user is reproduced as a ring tone.

  On the other hand, when the position designated by the user is after the last position indicated by the bar B22 (step S307: No), 45 seconds or more have elapsed from the start position of the chorus A. That is, when the position designated by the user is set as the end point, the entire range of the designated default part (Rabi A) cannot be included in the ring tone. In this case, the music editing unit 181 notifies the user that the entire range of the designated default part (Chain A) cannot be included in the ringtone, and a pop-up window PW2 as shown in FIG. Is displayed on the display unit 143 (step S310).

  As shown in the figure, the pop-up window PW2 displays a message indicating that not all of the chorus A can be included in the ringtone at the specified end point, and therefore the default start point, that is, the start position of the chorus A is not set as the start point. The

  In this case, the music editing unit 181 determines the position designated by the user as the end point of the ring tone, and sets the playback range as the playback range for the minimum playback time until this end point. That is, the music editing unit 181 accesses the storage unit 190, sets elapsed time information indicating the position specified by the user as an end point in the “playback range” in the full music file of the music, and is 5 seconds from this start point. Elapsed time information indicating the previous (minimum playback time) position is designated as a starting point (step S311).

  That is, if the default part desired by the user is chorus A, but the entire range of chorus A cannot be included as a ring tone, the position starting from the position specified by the user by the minimum playback time is set as the default start point. To do. Here, the starting point is automatically changed. In this case, a range of 5 seconds from the default start point is reproduced as a ring tone.

  Note that the playback time when the entire range of the default part cannot be included is not limited to the minimum playback time and is arbitrary.

  When the start point is designated in step S311, the process ends, and the flow returns to the “editing process” flow shown in FIG. In this case, a range from the position designated by default to the end point designated by the user is reproduced as a ring tone.

  On the end point designation screen EW, when “end point” is selected without selecting the “reproduction” column (step S303: No), the end position of the chorus A is designated as the end point. In this case, the designated position is set as the end point without playing the music. Here, since the position designated by the user is the end position of the chorus A, it is within the allowable range defined by the foremost end position and the end position (step S306: Yes, S307: Yes). Accordingly, the end position of the chorus A is designated as the end point (step S308), and the start position of the chorus A is designated as the start point (step S309). That is, the entire range of the chorus A is set as the ring tone.

  In the “editing process” shown in FIG. 5, when the range desired by the user is designated by the “start point setting process” or “end point setting process” and the playback range information is recorded in the full music file, the playback range information is included in the playback range information. Based on this, “save processing” for cutting out and storing the music data as the actual data is executed (step S400). This "save process" will be described with reference to the flowchart shown in FIG.

  First, the music editing unit 181 accesses the full music folder in the storage unit 190 and refers to the full music file of the music for which the reproduction range is set. Then, the attribute information is copied from the full music file (step S401), and the reproduction range information recorded in the “reproduction range” is acquired (step S402).

  Next, the music editing unit 181 extracts a portion corresponding to the range indicated by the acquired reproduction range information from the music data recorded in the “actual data” of the full music file (step S403). That is, the music data in the range from the start point to the end point indicated by the elapsed time information is cut out and copied. Here, the range to be cut out is specified based on the reproduction time information included in the music data.

  The music editing unit 181 accesses the ringtone folder in the storage unit 190, creates a new file including the attribute information copied in step S401 and the music data copied in step S403 (step S404), and ends the process. .

  Through the “save process”, music data in a range desired by the user is saved in the storage unit 190 as a ringtone file. That is, a portion corresponding to the reproduction range designated by the user is extracted from the music data indicating the full music and stored. Then, the playback unit 182 plays back the music data of the ringtone file stored in the ringtone folder in response to the incoming call (incoming call) of the voice call by the receiving unit 123, and outputs it as a music ringtone. That is, music data in a reproduction range designated by the user is reproduced as a ring tone.

  Thus, according to the mobile communication terminal 100 according to the above-described embodiment, a desired portion in the designated music can be used as a ring tone.

  Here, when setting the reproduction range, a screen display is performed so that the start point and the end point are designated based on the characteristic part (such as rust) of the music as a default reference based on the acquired configuration information (music characteristic information). For this reason, by designating a desired default part, an arbitrary range including the default part can be easily set as a ring tone.

  Also, it is determined whether the specified start point or end point is within the allowable range based on conditions such as playable time (maximum playback time or minimum playback time). Since the start point or the end point is changed, the ringtone of an appropriate reproduction range can be easily specified.

  In the above-described embodiment, the case where any default part is selected in the “editing process” has been described. However, when “no reference” (see FIG. 9A) is selected, the entire music piece is selected. The user designates the start point and end point at any position of. Also in this case, the same start point designation screen and end point designation screen as in the above embodiment are displayed.

  The said embodiment is an example and the application range of this invention is not restricted to this. That is, various applications are possible, and all embodiments are included in the scope of the present invention.

  For example, in the above embodiment, when “play” is selected in “start point setting process” or “end point setting process”, playback is started from the beginning of the music. However, the present invention is not limited to this. For example, the cursor at that time The music may be played from the position. In this case, for example, the user may select whether to play from the beginning of the music or from the cursor position.

  In the above embodiment, the music data of the portion corresponding to the designated reproduction range is extracted and saved as a ringtone file. However, the present invention is not limited to this. By reproducing only the indicated part, a part corresponding to the designated reproduction range may be output as a ring tone.

  Moreover, in the said embodiment, although the ringtone control part 180 identified the time position etc. of the predetermined | prescribed structural part (default part) based on the delivered structural information (music feature information), the structural part is identified. The method is not limited to this and is arbitrary. For example, the mobile communication terminal 100 may identify a predetermined component based on the reproduced music. In this case, for example, each component may be identified by detecting the pitch, tempo, key, tone color, etc. of the reproduced music. In addition, when a song includes a singing voice, each component of the song may be identified by recognizing lyrics by a technique such as voice recognition. According to such a method, the above-described editing process can be executed without distributing the configuration information. For example, music data is acquired from a sound source such as a CD that does not include the configuration information, and is used as a ring tone. Even when used, the above-described editing processing and the like can be realized.

  Moreover, in the said embodiment, although the case where the music containing a singing voice was made into a ringtone was illustrated, the form of the music made into object is not restricted to this, For example, it is a music only of performance, narration, etc. Also good. In this case, the configuration information corresponding to the music data is arbitrarily set according to the form of the target music.

  Note that the configuration of the ringtone control unit 180 and the like according to the above embodiment may be realized by software processing of the control unit 110 as well as by hardware. In this case, the control unit 110 is caused to function as the ring tone control unit 180 and the like, and a program for realizing each process described above is stored in the mobile communication terminal 100 (for example, the storage unit 190). Such a program is executed.

  In addition, the mobile communication terminal 100 according to the embodiment can be provided by applying the program to an existing mobile communication terminal as well as being able to be provided as a mobile communication terminal 100 in which such a program is incorporated in advance. It can also function.

  The method for providing such a program is arbitrary. For example, the program may be provided via a communication medium such as the Internet, or may be stored and distributed in a recording medium such as a memory card.
