  Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. The embodiment described below is an embodiment when the present application is applied to an information reproducing / recording apparatus.

  First, the configuration and function of the information reproducing / recording apparatus according to this embodiment will be described with reference to FIG. FIG. 1 is a diagram showing a schematic block example of the information reproducing / recording apparatus according to the present embodiment.

  As shown in FIG. 1, the information reproduction / recording apparatus 1 includes an information reproduction unit 11, an information output unit 12, a music feature amount extraction unit 13, an information recording / reproduction unit 14, an operation / display unit 15, a microphone 16, and a voice recognition unit 17. A communication unit 18 for performing data communication with the information distribution server 2 via the network 3 and a system control unit 19 are provided.

  Under the control of the system control unit 19, the information reproducing unit 11 is a CD (Compact Disc: a generic term for CD-DA (Digital Audio), CD-R, CD-R / W, etc.), MD (Mini Disc), DVD (Digital Versatile Disc: Generic name for DVD-Audio, DVD-Video, DVD-R, DVD-RW, etc.) or music recorded on a recording medium (recording means) such as a card-type recording medium (for example, memory stick, SD card, etc.) (An example of the presentation information of the present application) is reproduced, and the music is output to the information output unit 12, the music feature amount extraction unit 13, and the information recording / reproduction unit 14.

  For example, when the information reproducing unit 11 reproduces music recorded on a CD (for example, CD-DA), the information reproducing unit 11 irradiates the CD with a light beam to record information (not shown). Pickup that optically reads and photoelectrically converts the signal into an electrical signal, outputs an RF amplifier that generates and outputs an RF (Radio Frequency) signal from the electrical signal output from the optical pickup, and performs predetermined demodulation processing on the RF signal And a digital signal processing circuit (for example, constituted by a DSP (Digital Signal Processor) or the like) that performs error correction processing and the like to convert it into a digital signal and reproduces the music, and a servo circuit that servo-controls the spindle motor and the optical pickup, etc. Play and output the music.

  In addition, the information reproducing unit 11 includes, on a recording medium, accompanying information accompanying the music (for example, text information such as a music title, genre (eg, rock, jazz, pop, classic, hip hop, etc.)), artist name, If the production date is recorded (for example, when the recording medium is CD-TEXT or the like), the information reproducing unit 11 is connected to the system control unit 19. Under the control, the associated information is read from the recording medium and output to the information recording / reproducing unit 14. Further, in the present embodiment, the accompanying information is handled as an example of feature information representing the feature of the music.

  Note that the configuration and function for reproducing music from a recording medium other than a CD are known techniques, and thus detailed description thereof is omitted. Further, a music piece may be played from a plurality of recording media like a multimedia player.

  Although not shown, the information output unit 12 inputs music (digital audio signal) reproduced by the information reproduction unit 11 or audio guide information output from the system control unit 19 and converts it into an analog audio signal. A DAC (Digital-to-Analog Converter), an AMP (Amplifier) that amplifies and outputs the analog audio signal, a speaker that outputs the amplified analog audio signal as a sound wave, and the like are provided, and music is output from the speaker. It is like that.

  The music feature quantity extraction unit 13 is configured by, for example, a DSP, inputs the music reproduced and output by the information reproduction unit 11, extracts the music feature quantity indicating the characteristics of the music from the music data, and receives information. The data is output to the recording / reproducing unit 14 and the system control unit 19.

  Here, the music feature amount is information (for example, represented by a numerical value between 0 and 300) that quantitatively indicates the feature of the music, and is obtained from, for example, a musical tone of the music. Includes musical features. In the present embodiment, the music feature amount is also treated as an example of feature information representing the feature of the music.

The musical feature values include keys (key tones in C major, A minor, etc.), key change positions (or change patterns), chords (Minor, Major), chord change positions (or change patterns), Chord change amount (CPM: Code Per Minute) (or rate of change (HVL)), beat (beat: constant pulse signal with strength), maximum value (or minimum value, average value) of the beat, Beat change position (or change pattern), change amount of the beat (BPM: Beat Per Minute, representing tempo) (or rate of change), maximum intensity or average intensity (average volume) of musical sound, change position of volume (or Change pattern).

  Since various known methods can be applied to the extraction of these musical sound feature values, detailed description thereof is omitted. For example, the music feature value extraction unit 13 converts the music data into a fast Fourier transform (Fast Fourier Transform). ) To analyze the frequency and calculate the volume value for each frequency at a predetermined time interval along the time axis, and the key and the amount related thereto (key change position, etc.), the code and the amount related thereto (the code change position, etc. The amount of beat and the amount related to this (the maximum value of the beat (signal), etc.) are extracted by extracting the waveform or the like related to the music data at a predetermined threshold level.

  Such a musical sound feature amount (hereinafter referred to as a music feature amount) is used, for example, for the tone determination of the music by the system control unit 19. In this music tone discrimination process, for example, a music tone association table that preliminarily sets and stores a music feature amount and a music tone is used, and is performed based on the music feature amount of the music.

  FIG. 2 is a diagram illustrating an example of a music tone association table. In the example shown in FIG. 2, “bright song”, “smooth song”, “quiet song”, “sad song” are shown as the tune, and “key”, “chord of chord” are shown as the song feature amounts. “Change rate (HVL)”, “beat change amount (BPM)”, “maximum beat value”, and “average volume” are shown.

  In FIG. 2, “high”, “medium”, and “low” mean the music feature amount levels. For example, in the case of a beat change amount (BPM), “high” is 190 to 300. In the level (numerical value) range, “medium” is represented by a level range of 90 to 189, and “low” is represented by a level range of 0 to 89 (hence, “medium to high” represents 90 to 300 level range, “low to medium” represents a level range from 0 to 189). For example, in the case of an average volume, “high” is a level range of 1.2 to 2, “medium” is a level range of 0.6 to 1.19, and “low” is a range of 0 to 0.00. Represented in 59 level ranges. In FIG. 2, “C major” or “B minor” is shown as an example of “key”, and this is also expressed, for example, in a certain level range.

  When music tone discrimination processing is performed with reference to such a music tone association table, for example, whether the music feature quantity of the identified music satisfies the music feature quantity level corresponding to “bright music” (in other words, For example, whether or not it falls within the numerical range shown in FIG. 2 is determined, and if satisfied, the music is determined to match the “bright music” (the same applies to other music tones). Once the tune of the music is thus determined, information indicating the determined tune is registered in a music list described later in association with the music.

  In the present embodiment, the music tone is also treated as an example of the characteristic information representing the characteristics of the music.

  The information recording / reproducing unit 14 includes, for example, a buffer memory that temporarily stores music data, an encoder / decoder for encoding (compressing) or decoding (decompressing) music data, an HD (Hard Disc), And an HD drive for recording music data or the like on the HD or reproducing from the HD.

  The information recording / reproducing unit 14 may be configured to include a recording medium such as an MD, a DVD-RW, or a card type recording medium.

  Then, under the control of the system control unit 19, the information recording / reproducing unit 14 compresses, for example, the music data output from the information reproducing unit 11 and records it on the HD, and also outputs from the information reproducing unit 11. The accompanying information is recorded on the HD in association with the music. The information recording / reproducing unit 14 records the music feature amount output from the music feature amount extracting unit 13 in association with the music under the control of the system control unit 19.

  Further, the information recording / reproducing unit 14 is distributed from the information distribution server 2 via the network (for example, composed of the Internet, a mobile communication network, etc.) 4 under the control of the system control unit 19 and via the communication unit 18. The received music data and accompanying information associated therewith are recorded on the HD.

  Note that the musical tone feature quantity of the music acquired from the information distribution server 2 is also extracted by the music feature quantity extraction unit 13 at the time of acquisition, for example, and recorded in association with the music.

  As described above, each music recorded on the HD in the information recording / reproducing unit 14 is given a unique registration number (for example, a serial number) and is managed in a list. For example, the registration number of the music recorded on the HD, the data capacity, the recording location, the performance time, the accompanying information, the jacket image of the music (for example, the image of a single CD jacket), the title of the album and the jacket image (for example, And management information such as music feature quantities are registered in the music list. The music list data is recorded in, for example, an HD, and is appropriately read and used by the system control unit 19.

  The accompanying information attached to the music is input by the user operating the operation / display unit 15 when the music data is recorded on the HD, and is registered in the music list as the management information. good.

  In addition, the system control unit 19 reads out TOC (Table of content) information recorded on the innermost periphery of the CD, for example, and uses a server (not shown) having a known CDDB (CD database) using the TOC information as a key. ) Through the network 4 and obtain from the server the accompanying information of the music recorded on the CD and the jacket image (or the jacket image of the album if the music was recorded on the album CD), etc. The management information may be registered in the music list.

  The operation / display unit 15 includes, for example, a touch panel display panel (for example, a liquid crystal panel). Under the control of the system control unit 19, the management information included in the music list and various instructions for the user to input various instructions are displayed. Operation buttons are displayed. When such an operation button is pressed, an instruction signal corresponding to the operation button is output to the system control unit 19. Further, a music icon as an example of a display object corresponding to each music is displayed on the display panel. When the music icon is pressed (touched), the music corresponding to the music icon is displayed. For example, an instruction signal indicating a reproduction instruction is output to the system control unit 19. A remote controller provided with the operation button may be used in combination.

  For example, the microphone 16 detects (collects) voices related to various instructions uttered by the user and outputs the voice signals to the voice recognition unit 17.

  The voice recognition unit 17 performs known voice recognition processing, performs frequency analysis of the voice signal from the microphone 16, and selects the most suitable candidate from the prepared speech voice candidate group. Information included in the audio signal (for example, instruction information for selecting music) is recognized and output to the system control unit 19.

  The system control unit 19 includes a CPU having an arithmetic function, a working RAM, various processing programs (including an information processing program and a display control processing program), a ROM that stores data, and the like. It is an example of a display control apparatus. Note that the information processing program and the display control processing program may be downloaded from a predetermined server connected to the network 3, for example, or recorded on a recording medium such as a CD-ROM and stored in the recording medium. You may make it read via a drive.

  When the CPU executes a program stored in the ROM or the like, the system control unit 19 performs overall control of the information reproduction / recording apparatus 1 and performs recording and reproduction control of music.

  Furthermore, the system control unit 19 selects music to be played from music registered in the music list (that is, a plurality of music recorded on the HD) based on a predetermined selection condition. The predetermined selection condition may be a preset condition or a condition instructed by the user. For example, when the user has instructed the condition “select 20 songs from rock or jazz”, the management information of each song registered in the song list is referred to and 20 songs corresponding to rock or jazz are selected. Will be. Alternatively, when the user instructs the condition “select all songs registered in the song list”, all the songs registered in the song list are selected.

  Then, the system control unit 19 serves as a feature information acquisition unit, and includes one or a plurality of feature information (hereinafter, “ "Determined element feature information") is obtained from, for example, a music list, and overall feature information representing the characteristics of the entire selected pieces of music is determined based on each of the obtained determined element feature information as overall feature information determining means It is supposed to be. For example, if the decision element feature information is a tone such as a bright song, a song with a good score, a quiet song, etc., the most characteristic tone is the entire feature information (for example, a song with a bright song is a song with a bright tone). In most cases, the characteristics of the entire music are brightly tuned). Further, the system control unit 19 notifies the user of the overall feature information determined as described above as the overall feature information notification unit.

  Here, the notification of the overall feature information is made by displaying information including the overall feature information (for example, information that “the overall feature of the music is a bright song”) on the display screen of the operation / display unit 15. However, it is desirable that the overall characteristics of the entire song (in other words, the atmosphere and impression of the entire song) can be grasped instantaneously (for example, at a glance or in an instant). Audio corresponding to the information is output from the information output unit 12, or a predetermined area (for example, background) on the display screen is a color corresponding to the entire feature information (for example, a bright song is orange, a song with a good score) In this case, it may be displayed in red or the like), a pattern, or a picture (for example, a picture of a person or a landscape shown in a photograph, a picture drawn by a person, or the like).

  It should be noted that which feature information is determined element feature information can be arbitrarily set by the user through the operation / display unit 15, for example.

  In addition, some of the above-described feature information can represent the level. For example, the amount of beat change has a level of 1 to 300, and the average volume has a level of 1 to 2. . In addition, for example, the era has levels from 1960, 1970, 1980, 1990, and 2000 (the era may be a level from the past (for example, the 1600s) and the interval between them. Also, it may be every year (for example, 2002, 2003, 2004, etc.), every month, or every second.

  The system control unit 19 includes three pieces of feature information (first feature information representing the first feature, second feature information representing the second feature, and second feature) of the selected music pieces. Information indicating the respective levels (hereinafter referred to as first feature level information, second feature level information, and third feature level information), respectively, as display control means For each song, Y is a position corresponding to the level of the first feature information in the X (horizontal) axis (an example of the first axis) direction on the display screen of the display panel, and is orthogonal to the X-axis direction. The music icon is displayed at a position corresponding to the level of the second feature information in the (vertical) axis (an example of the second axis) with the size of the music icon corresponding to the level of the third feature information. It has become.

  Note that which feature information is used as the first feature information, the second feature information, and the third feature information can be arbitrarily set by the user through the operation / display unit 15, for example.

  FIG. 3 is a diagram illustrating a display example of music icons corresponding to music on the display screen. In the example of the music icon display screen shown in FIG. 3, four music icons 51 to 54 having different sizes are shown. On the music icons 51 to 54, for example, the title of each music (in the example of FIG. 3). , The title of the song (Track A, Track B, etc. are represented) and an image of the jacket corresponding to each song are displayed on the song icon (for example, an image of the national flag of the country of production of the song (for example, , Stored in advance) may be displayed.

  The size of the music icons 51 to 54 represents the level of the age (an example of the third characteristic information), and the music icon has a smaller size as the music is older (for example, 1950s). (In terms of image, the age is older (for example, 1950s) as it goes in the depth direction (Z axis)). In the example of FIG. 3, the X-axis direction indicates the level of average volume (an example of first feature information), and the Y-axis direction indicates the level of BPM (beat variation) (an example of second feature information). For example, the music icon 54 of a music having a large (high) average volume level is located on the right side in the X-axis direction (note that the music located in the upper right part is a music with good momentum (eg, dance music). On the other hand, the music located at the lower left is a gentle and quiet song (for example, a ballad or the like). Further, although not shown, the background screen excluding a plurality of music icon portions is displayed in a color, pattern, or picture corresponding to the above-described overall characteristic information that represents the characteristics of the entire music.

  When the music icon displayed in this way is designated (touched), the system control unit 19 performs, for example, a reproduction process of the music corresponding to the music icon. Then, a plurality of music icons displayed on the display screen are displayed in an overlapping manner.

  For example, FIG. 4A is a diagram illustrating an example of a case where a plurality of (20 songs in this example) music icons are displayed on the display screen. As described above, when a plurality of music icons are displayed so as to overlap each other, it becomes difficult for the user to grasp what music icon of the music is displayed, and further, it is difficult to specify the music icon. .

  Therefore, for example, when the number of selected music pieces is a predetermined number (for example, 15 music pieces) or more, or when music piece icons are displayed in an overlapping manner, the system control unit 19 serves as a group determining unit between each piece of music piece. The first feature information level difference is less than or equal to a first predetermined value, the second feature information level difference is less than or equal to a second predetermined value, and the third feature information level difference is a third predetermined value. A plurality of the following songs are determined as one group, and as representative presentation information determining means, one of the plurality of songs belonging to the determined group is determined as a representative song, and a music corresponding to the representative song Only icons are displayed.

  Accordingly, in the examples of FIGS. 4A and 4B, four groups of groups A to D are determined. In group A, “Track A” music is recorded, and in group B “Track L” music is The music of “Track T” in group C and the music of “Track K” in group D are determined as representative music, and music icons 54, 61, 62, and 63 corresponding to the respective representative music are displayed. Yes.

  The representative music represents, for example, the music that matches the above-described overall characteristic information from a plurality of music belonging to the group, that is, the characteristics of the entire selected music (in other words, closest to the characteristics of the entire music). A song is selected and determined. Or you may make it determine at random from the some music which belongs to a group.

  Details of the group determination process will be described later.

  Next, the operation of the information reproducing / recording apparatus 1 configured as described above will be described with reference to FIGS.

  5 and 6 are flowcharts showing music icon display processing in the system control unit 19 of the information reproducing / recording apparatus 1. FIG. In the following description, “musical tone” is set as decision element feature information, “average volume” is set as first feature information, “BPM” is set as second feature information, and “age” is set as third feature information. It is assumed that

  When the processing shown in FIG. 5 is started, the system control unit 19 reads the above-described music list and various tables from the information recording / reproducing unit 14 and waits for input from the user.

  For example, when the user utters “select 20 songs from rock or jazz” as a music selection condition, the sound is collected (input) by the microphone 16, and the selection condition is recognized by the voice recognition unit 17. Information is output to the system control unit 19. On the other hand, the system control unit 19 recognizes the selection condition indicating “select 20 songs from rock or jazz” from the voice recognition unit 17, and selects a song satisfying the selection condition from the song list (step S1). As a result, for example, a total of 20 songs corresponding to rock and music corresponding to jazz are selected.

  A plurality of selection conditions may be displayed on the display screen of the operation / display unit 15, and a music piece may be selected according to the selection conditions pressed by the user.

  Next, the system control unit 19 determines the determination element feature information “musical tone”, the first feature level information “average volume level”, the second feature level information “BPM level”, and the third feature level information for each selected song. The “age level” is acquired from the music list (step S2). The information thus obtained is stored in a table format in a predetermined area on the RAM.

  FIG. 7 is a diagram illustrating an example of feature information acquired by the system control unit 19. In the example of FIG. 7, the titles, tunes, average volume levels, BPM levels, and era levels of 20 songs are associated with each other.

  Next, the system control unit 19 determines overall feature information representing the features of the selected plurality of pieces of music based on the acquired determination element feature information “musical tone” of each piece of music (step S3). For example, in the example of FIG. 7, there are as many as 8 songs that are bright songs, so a bright song is determined as the overall feature information.

  Next, the system control unit 19 determines and stores a background color corresponding to the determined overall feature information with reference to a background color correspondence table that defines the association between the music tone and the background color, for example (step S4). In the background color correspondence table, for example, an orange color is associated with a bright song, a green color is associated with a healing song, and a red color is associated with a good song, The background color corresponding to the determined overall feature information is determined.

  Note that such association can be arbitrarily set by the user. Further, instead of the background color correspondence table, for example, a background pattern correspondence table that defines the correspondence between the tone and the background pattern may be referred to, and the background pattern corresponding to the overall feature information may be determined. In this case, for example, a pattern that can image a bright song is set for a bright song, and a pattern that can image a healed song is set for a song that is healed. Furthermore, instead of the background color correspondence table, for example, a background picture correspondence table that defines the correspondence between music tone and background picture may be referred to, and the background picture corresponding to the entire feature information may be determined. In this case, for example, a picture (for example, a landscape photograph image) that can image the music to be healed is set for the music to be healed.

  In addition, when there are two or more pieces of decision element feature information that are most common in step S3, for example, when the number of songs that are songs with bright tunes and the number of songs that are songs that are healed is the same, the number is bright. A background color (for example, a mixed color or an intermediate color) obtained from the background color corresponding to the song and the background color corresponding to the song to be healed may be determined in step S4.

  Furthermore, the audio information corresponding to the determined overall feature information may be determined. For example, when there are the most bright songs, the audio information such as “the most bright songs” is displayed. If there are the same number of bright and healing songs, the voice information such as “the most bright and healing songs” may be determined. .

  Next, the system control unit 19 identifies one piece of music from among the selected music pieces (step S5), and the first feature level information “average volume level” and second feature level information “BPM level” of the song. ”And the third feature level information“ level of age ”, the display position and size of the music icon corresponding to the specified music are determined (step S6), and stored in association with the music.

  Here, in the present embodiment, for example, the “average volume level” shown in FIG. 7 corresponds to the X coordinate, and the “BPM level” corresponds to the Y coordinate, and the display corresponding to the X and Y coordinates is shown. The position on the screen is determined as the music icon display position (that is, the position of the center point of the music icon). The size of the music icon is determined by referring to a music icon size association table that defines the association between the age level and the size of the music icon, for example. In the music icon association table, for example, the music icon size is “128 × 128 pixels (bitmap image)” for the age “2000”, and the music icon size is for the age “1980”. “96 × 96 pixels” are associated with each other, and thereby the size of the music icon corresponding to the specified music is determined.

  Next, the system control unit 19 determines whether or not all the selected music pieces have been specified in step S5, that is, whether or not the display position and size of the music icon have been determined (step S7), and for all the music pieces. If not specified (step S7: N), the process returns to step S5 to specify unspecified music (for example, specified in the order of No. shown in FIG. 7), and in the same manner as above, the specified The display position and size of the music icon that has been performed are determined.

  Thus, when the display position and size of the music icon are determined for all of the selected music (step S7: Y), the system control unit 19 determines the background color (or background pattern, background picture) determined above, In accordance with the title and jacket image of each selected song and the display position and size of the song icon, as well as the display screen configuration data prepared in advance, the song icon display screen as described above is configured and operated and displayed. The data is displayed on the display panel in the unit 15 (step S8). The user grasps the entire feature information based on the background color (or background pattern or background picture) displayed in this way.

  When the entire feature information is notified to the user by voice, the voice information determined when the music icon display screen is displayed (for example, “the brightest music is the most”) is information. Audio is output from the output unit 12. Further, at this time, among the plurality of selected music pieces, the artist name, genre, age, etc. that are most common may be determined, and the information may be output from the information output unit 12 as audio.

  Next, the system control unit 19 determines whether or not there are a predetermined number (for example, 15 songs) or more of the selected music pieces (step S9), and if there is no predetermined number or more (step S9: N), for example, FIG. When the number of music icons to be displayed is small, the process is terminated, and the selection process for music reproduction (not shown) is started while maintaining the display of the music icon display screen. For example, when a music icon on the music icon display screen is designated (selected) (touched) by the user, the system control unit 19 highlights (highlights) the designated music icon, and the music The music corresponding to the icon is reproduced from the information recording / reproducing unit 14.

  On the other hand, if there is a predetermined number or more in step S9 (step S9: Y), for example, if there are many music icons displayed as shown in FIG. 4A, the music group determination processing in step S10. It is transferred to.

  In step S9, the system control unit 19 determines whether or not the music icons overlap a predetermined number (for example, five) or more, instead of determining whether or not the selected music is a predetermined number or more. If the number overlaps more than a few, it may be configured to shift to the music group determination process in step S10.

  In the music group determination process, as shown in FIG. 6, the system control unit 19 first specifies one music from the selected music (step S11), the specified music, and the first feature information. Difference in level of “average volume” is not more than a first predetermined value, difference in level of second feature information “BPM” is not more than a second predetermined value, and difference in level “age” of third feature information It is determined whether or not there is a song whose value is equal to or less than the third predetermined value (step S12). If there is such a song (step S12: Y), the song is extracted (step S13), and so on. If there is no correct music (step S12: N), the process proceeds to step S15.

  FIG. 8 is a diagram for explaining the level difference of the first feature information “average volume” and the level difference of the second feature information “BPM”, and corresponds to each piece of music shown in FIG.

  For example, if the music (Track E) corresponding to the music icon 71 shown in FIG. 8 is specified in step S11, first, the difference between the music and the age level is a third predetermined value (for example, 9) or less. Music is searched. In the example shown in FIG. 7 and FIG. 8, there are four tracks A, Track F, Track H, and Track O that have a track level difference of 9 or less, for example. Music (that is, music having the same music icon size) is searched and extracted. Since the age level of the track “Track B” is 1980, the difference between the track level “Track E” and the age level is “20” and is not extracted.

  Subsequently, among the extracted songs, the difference between the “Track E” song and the average volume level is a first predetermined value (for example, 0.4: the width of the song icon corresponding to the song of “Track E” ( BPM corresponding to the height (H) of the music icon corresponding to the music of the second predetermined value (for example, 95: “Track E”). Music) that is less than or equal to level) is searched.

  Here, the difference in average volume level is equal to or lower than the average volume level corresponding to the width (W) of the music icon, and the difference in BPM level is equal to or lower than the BPM level corresponding to the height (H) of the music icon. This means that there is an overlapping portion (or a contact portion) between the music icons. For example, as shown in FIG. 8, the difference in the average volume level between the “Track E” music and the “Track F” music is “0.3”, and the BPM level difference is “21”. Since the condition is satisfied (there is an overlapping portion between the music icon 71 and the music icon 72), the music of “TrackF” is searched and extracted. In addition, in the example of FIG. 8, the music icons corresponding to the “Track A” and “Track H” music also satisfy the condition and overlap with the music icon 71 corresponding to the “Track E” music. So it will be searched and extracted. Note that the music icon corresponding to the “Track O” music does not satisfy the condition, and there is no overlapping portion (or a portion in contact with) the music icon 71 corresponding to the “Track E” music. Not.

  Note that the ratio (for example, A2 / A1) of the overlapping area A2 of the music icon to the area A1 of the entire music icon is small (for example, the area A2 of the overlapping area is 1 / of the area A1 of the entire music icon. In the case of 5 or less), the first and second predetermined values in the determination may be set so that the music is not extracted (that is, not grouped). In this case, in the example of FIG. 8, the first predetermined value is set smaller than the level of the average volume corresponding to the width (W) of the music icon corresponding to the specified music, and the second predetermined value is specified above. It is set to be smaller than the BPM level corresponding to the height (H) of the music icon corresponding to the music.

  In addition, when searching for a song in which the difference between the specified music and the average volume level is less than or equal to a first predetermined value and the difference in BPM level is less than or equal to a second predetermined value, the display screen to be displayed is a grid. You may comprise so that it may be divided | segmented into (grid) and performed.

  FIG. 9 is a diagram illustrating an example of a music icon display screen divided into grids. In this case, the music corresponding to the music icon whose number of grids included in the overlapping portion with the music icon corresponding to the specified music is a predetermined number (for example, one or more) is extracted. In the example of FIG. 9, the number of grids included in the overlapping portion 73 of the music icon 71 corresponding to the specified “Track E” music and the music icon 72 corresponding to the “Track F” music is a predetermined number (for example, 1 Therefore, the music of “TrackF” is extracted.

  Next, the system control unit 19 determines a music group based on the music thus extracted (step S14). For example, when the “Track E” music is specified as described above, the “Track E” music and the extracted “Track A”, “Track F”, and “Track H” music are combined into one group. For example, it is stored as “Group A”.

  Next, the system control unit 19 determines whether or not all the selected music pieces have been specified in step S11 (step S15). If all the music pieces have not been specified (step S15: N), step Returning to S11, the music that has not been specified is specified. Similarly to the above, the difference between the specified music and the level of the first feature information “average volume” is equal to or less than the first predetermined value, and the second feature information. A music piece whose level difference of “BPM” is equal to or smaller than the second predetermined value and whose level “age” of the third feature information is equal to or smaller than the third predetermined value is extracted.

  In the example of FIG. 8, when the track “Track E” is identified in step S11, the track “Track O” is not extracted (since the track icons are not overlapped), but the track “Track A” When the music is specified in the above step S11, the music of “TrackO” is extracted (because the music icons are not overlapped). As a result, the music of “TrackE” and the music of “Track O” are extracted. Belong to the same group.

  Further, in the example of FIG. 8, when the track “Track D” is identified in step S11, the difference between the “Track D” track and the average volume level is equal to or less than the first predetermined value, and the BPM The music whose level difference is equal to or smaller than the second predetermined value is searched for, and the first predetermined value is an average volume level corresponding to the width (W) of the music icon corresponding to the music of the “TrackD”, The second predetermined value is a BPM level corresponding to the height (H) of the music icon corresponding to the music of “TrackD”. That is, the first predetermined value and the second predetermined value change depending on the size of the music icon corresponding to the music specified in step S11.

  In this way, when all the selected music pieces are specified in step S11 and the determination of the group is confirmed, the system control unit 19 determines a representative music piece in each determined group (step S16).

  For example, as described above, from among a plurality of songs belonging to the group, a song that matches the overall feature information determined in step S3, that is, a song that best represents the characteristics of the entire selected song is determined as the representative song. . For example, if the overall feature information is a bright tone, a song having a bright tone is determined as the representative song. In this case, when there are a plurality of music pieces having a bright tone as the overall feature information (for example, in the example of FIG. 4A, the music pieces of Track A, Track E, and Track H that belong to the group A are applicable. ) For example, the music with the highest (larger) music tone level is determined as the representative music. For example, the level of the bright tone is obtained by multiplying each piece of music by a predetermined weighting amount such as the chord change rate, beat change amount, beat maximum value, and average volume shown in FIG. It is determined by calculating the sum of chord change rate, beat change amount, maximum value of beat, average volume, etc., and by comparing the level of bright tone of each song, the representative song is Will be decided.

  On the other hand, when there is no song having a bright tone as the overall feature information (for example, group B in the example of FIG. 4A), the song closest to the brightest tone is determined as the representative song. . For example, for each piece of music, for example, the chord change rate, beat change amount, beat maximum value, average sound volume, and the like shown in FIG. The sum of the amount of change, the maximum value of the beat, the average sound volume, and the like is calculated, and the song whose calculated value is closest to the bright tone level is determined as the representative song.

  Note that the representative music may be configured to be determined by various methods other than this, for example, considering the display positional relationship (balance) with the music icon corresponding to the representative music in another group. It may be determined (for example, not to approach more than a predetermined distance).

  When the representative music in each group is determined in this way, the system control unit 19 displays the determined background color (or background pattern, background picture), the title and jacket image of the determined representative music, and the display position of the music icon, In accordance with the size and display screen configuration data prepared in advance, for example, a music icon display screen as shown in FIG. 4B is configured and displayed on the display panel of the operation / display unit 15 (step S17), the process returns to the process shown in FIG. Then, in the same manner as described above, selection processing for music reproduction is started while maintaining the display of the music icon display screen. In the selection process in this case, for example, when a music icon corresponding to the representative music on the music icon display screen is designated by the user, for example, the system control unit 19 belongs to the music corresponding to the designated music icon. The music icons of all the music in the group are displayed. When any of the music icons is designated by the user, the music icon is highlighted (highlighted), and the music corresponding to the music icon is recorded. Reproduction is performed from the reproduction unit 14.

  In step S3, the most popular tone among the selected music pieces is determined as the overall feature information. However, the method for determining the overall feature information is not limited to this. For example, The chord change rate, beat change amount, beat maximum value, average value of each song, and the average are calculated for each song feature amount, and the calculated chord change rate and beat change amount are calculated. 2, for example, it is determined which tune tones in the tune correspondence table shown in FIG. 2 matches the respective tune features such as the maximum value of the beat and the average volume, and the tune to match is determined as the overall feature information. You may comprise as follows. In this case, in step S16, the chord change rate, beat change amount, beat maximum value, average sound volume, and other sums (sums after multiplication by a predetermined weighting amount) of each song are further selected. The music piece closest to the sum of the respective average music feature values (the sum after multiplication by a predetermined weight) may be determined as the representative music piece.

  Further, the process of step S8 may not be performed immediately after the process of step S7, and may be configured to be performed for the first time when there are not a predetermined number or more of selected songs in step S9 (step S9: N). good.

  In addition, even if the music icon does not overlap with the music icon corresponding to the specified music in the above step S12, the music icon (for example, “TrackO”) that is closely related to the music icon corresponding to the specified music It may be configured such that music corresponding to the music icon corresponding to the music of No. 2 and the music icon corresponding to the music of “Track H” are extracted in a close relationship). In this case, in the example of FIG. 8, the first predetermined value is set to be larger than the average volume level corresponding to the width (W) of the music icon corresponding to the specified music, and the second predetermined value is specified. It is set to be larger than the BPM level corresponding to the height (H) of the music icon corresponding to the music.

  As described above, according to the embodiment, for each of the selected music pieces, the position according to the level of the first feature information in the X-axis direction on the display screen, and the Y-axis direction. Since the music icon is displayed at the position corresponding to the level of the second feature information with the size of the music icon corresponding to the level of the third feature information, the user can display the feature of each selected music. It can be grasped instantly (at a glance).

  In addition, music pieces having similar characteristics are grouped, and music icons corresponding to the representative music that most represents the characteristics of the entire music in the group are displayed at a display position and size corresponding to the characteristic information. Therefore, even when a large number of music pieces are selected and music icons are displayed in an overlapping manner, the user can easily grasp the characteristics of each selected music piece.

  In addition, by determining the overall feature information representing the features of the entire plurality of songs selected based on the determination element feature information of each song and displaying it with the background color or background pattern corresponding to the overall feature information, Since the feature information is notified to the user, the user can instantly (at a glance) grasp the atmosphere, impression, and the like of the plurality of selected pieces of music.

  In addition, if audio information (for example, “the most bright songs are the most”, etc.) corresponding to the overall feature information is output as audio, the user can change the atmosphere, impression, etc. of the selected plurality of songs. Even without looking at the display screen (for example, when the information reproducing / recording apparatus 1 is mounted on a vehicle, the user can also grasp the information instantaneously).

(Other embodiment 1)
In the above embodiment, the case where the average volume level is assigned in the X-axis direction, the BPM level in the Y-axis direction, and the age level is assigned to the size of the music icon has been described as an example. What characteristic information is assigned to the direction and the size of the music icon is arbitrary. For example, FIG. 10A is a diagram showing an example of a display screen when a chord level is assigned in the X-axis direction, a BPM level is assigned in the Y-axis direction, and an age level is assigned to the size of the music icon. FIG. 10B is a diagram showing an example of a display screen when the chord level is assigned in the X-axis direction, the average volume level is assigned in the Y-axis direction, and the age level is assigned to the size of the music icon. In both the examples of FIGS. 10A and 10B, the music corresponding to the music icon located at the upper right (for example, TrackW) is a bright and fast-tempo music (music with a vibrant atmosphere), and is located at the lower left. The music corresponding to the music icon to be played (for example, Track V) is dark and slow-tempo music (sad atmosphere music).

  In addition, for example, the number of CDs sold, the time when the artist was active, and the like may be assigned to the X-axis direction, the Y-axis direction, or the size of the music icon. Further, the size of the music icon may be constant and the feature information may be assigned only in the X-axis direction and the Y-axis direction.

  Furthermore, the feature information assigned to the X-axis direction, the Y-axis direction, or the size of the music icon may be configured to be shifted and rotated in accordance with an instruction from the user, for example. For example, in the state where the average volume level in the X-axis direction, the BPM level in the Y-axis direction, the age level is assigned to the size of the music icon, and the music icon display screen is displayed, When a predetermined operation button is pressed, the system control unit 19 responds accordingly by setting the age level in the X-axis direction, the average volume level in the Y-axis direction, and the BPM level in the size of the music icon. When the user presses a predetermined operation button, the system control unit 19 changes the BPM level in the X-axis direction and the Y-axis direction accordingly. The age level is changed to assign the average volume level to the music icon size, and the music icon display screen is displayed again.

(Other embodiment 2)
In the above embodiment, when the music icons overlap each other, the group determination process is performed. However, the music icon specified by the user is highlighted (highlighted) without performing the group determination process. In addition, a music icon corresponding to a music related to the music (hereinafter referred to as “related music”) may be highlighted (highlighted).

  FIG. 11 is a diagram illustrating an example in which a music icon corresponding to a related music is highlighted (highlighted). In the example of FIG. 11A, a plurality of music icons are displayed in an overlapping manner. For example, some of the music icons corresponding to the music of “Track A”, “Track J”, and “Track M” are other music icons. When the music icon corresponding to the music of “Track T” is specified, as shown in FIG. 11B, “Track A”, which is a related music of the music of “Track T”, is hidden. ”,“ Track J ”, and“ Track M ”are displayed in the foreground (front) and highlighted (highlighted). This makes it easy to specify music icons corresponding to the music pieces “Track A”, “Track J”, and “Track M”. Then, in the state where a plurality of music icons are highlighted (highlighted) as shown in FIG. 11B, if any one of the highlighted music icons is specified, the music icon corresponds to the music icon. Will be played.

  In addition, as related music related to the music corresponding to the specified music icon, for example, the music of the same artist as the artist of the specified music, or the same genre as the genre (for example, rock) of the specified music A song or a song in the same region as the designated song (for example, a country) may be used.

  The type of related music can be arbitrarily set by the user, for example, through the operation / display unit 15 (for example, the system control unit 19 determines the artist, genre, region, artist active time, etc.). The check button corresponding to each is displayed on the display panel, and the user designates and sets it).

  Even with this configuration, even when a large number of music pieces are selected and music icons are displayed in an overlapping manner, the user can easily grasp the characteristics of the selected music pieces.

(Other embodiment 3)
In the above embodiment, the music icon corresponding to each selected music is displayed on the display screen at the display position and size corresponding to the music characteristics, so that the user can select the characteristics of each music selected at a glance. The music icon corresponding to the desired music can be quickly specified. For example, when the information reproducing / recording apparatus 1 is mounted on a vehicle, the driver who is the user is driving the vehicle. Since the display screen cannot be seen, it is difficult to grasp the display position and size of the displayed music icon.

  Therefore, the spatial position of the music corresponding to the display position and size of the music icon may be presented to the user by voice.

  FIG. 12 is a diagram illustrating an example in which a spatial position of music corresponding to the display position and size of the music icon is presented to the user by voice. For example, in the example shown in FIG. 12, the intro part or the rust part of each piece of music is several seconds (for example, 5 seconds) in the order of “Track B” → “Track D” → “Track C” → “Track A”. In addition to the transition and reproduction, the volume is adjusted from the left speaker and the right speaker so that the user can grasp the spatial position of each piece of music.

  For example, the total volume of the left speaker and the right speaker is set to increase in the order of “Track D” → “Track C” → “Track B” → “Track A”. The volume of the left speaker is significantly larger than the volume of the right speaker. In the case of “Track A” music, the volume of the right speaker is significantly larger than the volume of the left speaker, and in the case of “Track D” music, the right speaker. The volume of the left speaker is set slightly higher than the volume of the left speaker, and the volume of the right speaker is set slightly higher than the volume of the left speaker in the case of “Track C” music.

  According to such a configuration, the spatial position of the music corresponding to the display position and size of the music icon can be easily grasped by voice without looking at the display screen. The music icon corresponding to the desired music can be quickly specified.

  Note that the present invention is not limited to the volume example, and can be applied to, for example, an echo, and can also be applied to a 5.1 channel surround system without being limited to the left speaker and the right speaker.

(Other embodiment 4)
In the above embodiment, the case where a jacket image or the like is displayed on the music icon has been described as an example. However, for example, a photographic image selected by the user may be displayed on the music icon.

  FIG. 13 is a diagram illustrating an example where a photographic image is displayed on a music icon.

  In the example of FIG. 13, music data corresponding to a love song, photo data representing a love song, and background data representing a love song are managed in association with each other by the love song folder. When the music icon (for example, a music selected by the user) is displayed, the photo images (photos A, B, and C) included in the photo data are displayed on the music icon and included in the background data. A background image is displayed. The association between each music piece and each photographic image may be set in advance by the user or may be randomly assigned. As another example of the love song, the present invention can be applied to a Christmas song and various other types of songs.

  Even if comprised in this way, the user can grasp | ascertain the atmosphere, the impression, etc. of the whole music in the said folder at a glance.

  Note that the present invention is not limited to an example in which music data, photo data, and background data are managed in association with each other by a folder. For example, music data is managed as a file, and tag information, photo data, and background data associated with the file are managed. And may be managed in association with each other. By doing so, even if the music data, the photo data, and the background data are not managed in the folder, the atmosphere, impression, etc. of the entire music can be grasped at a glance by classifying them in association with the tag information of the file.

(Other embodiment 5)
In the above embodiment, music (program information) has been described as an example of presentation information of the present application, but the present invention is not limited to this. For example, movies, broadcast programs, other contents (program information), and photographic images It is applicable to the above.

  For example, when a photographic image is taken as an example of the presentation information, the feature information of the photographic image can be obtained from information (for example, shooting date, place, etc.) added to the data of the photographic image. The photographic image can be obtained by image analysis. In the image analysis of the photographic image, for example, the hue (color tone) of each photographic image included in the plurality of photographic images selected by the user is extracted, and the most frequently used hue (color tone) is a feature of the entire photographic image. Is determined as overall feature information. For example, the level of the shooting date is assigned to the size of the photographic image icon as the display object, and the level of the location (first feature information) in the X-axis direction (for example, “1” for Japan, “ 2 ”, UK is leveled to“ 3 ”, etc., a color level (second feature information) is assigned in the Y-axis direction, and the photographic image icon is assigned a display position corresponding to the feature information level and If it is configured to display in size, the same effect as in the above embodiment can be obtained.

  Moreover, in the said embodiment, although demonstrated taking the example of the music icon used as selection object (designation object) as a display object of this application, it is not limited to this, The display object corresponding to presentation information, such as each music Any character, image, etc. can be used.

  Moreover, in the said embodiment, although the example which alert | reports whole characteristic information was demonstrated as the X-axis and Y-axis of a display screen, for example, the place name represented by the world map information by making the background of a display screen into world map information You may make it alert | report using the latitude longitude information of information. That is, you may alert | report by various aspects, regardless of one aspect.

  In the above embodiment, the present application is applied to the information reproducing / recording apparatus 1. However, the present invention can be applied to, for example, an AV (audio, visual) apparatus, a personal computer, and a PDA. Furthermore, the present invention can be applied to a vehicle-mounted navigation device.

  In addition, the entire disclosure of the Japanese patent application (No. 2005-63789) including the specification, claims, drawings and abstract filed on March 8, 2005 is referred to Incorporated here.
