Description

  The present invention relates to a music playback apparatus that plays back and outputs music, and a camera equipped with the same.

  Recently, music playback devices such as portable audio players that can acquire music data from CDs, MDs, the Internet, etc., and can easily listen to music regardless of location are rapidly spreading.

  The music playback device incorporates a memory such as a flash memory and a hard disk drive for storing a large number of music data. In the music reproducing apparatus, a list of music pieces represented by music data is displayed on a display device such as an LCD provided. In addition, for example, by operating an operation unit called a touch wheel or a click wheel, music can be played, stopped, fast-forwarded, rewinded, music to be played can be selected, and various settings can be made.

  Since a large amount of music data on the scale of several hundred to several thousand is stored in the memory of the music playback device, it is very troublesome to select the music to be played back from this. Therefore, conventionally, various proposals have been made for automatically reproducing music according to the user's preference while saving the user from having to operate the operation unit to select the music.

  For example, selection conditions that reflect the user's intention obtained from input means such as a voice recognition function, and information about songs (recorded album title, artist name, number of songs recorded in the album, total performance time, released A music playback device that selects and plays music that satisfies the selection conditions from music data stored on the hard disk drive based on the date, song name, performance time, genre, image, etc. (See Patent Document 1). In this music playback apparatus, music satisfying the selection condition is played back in the order of the released date, the order of the user's preference, or at random.

  In addition, there are multiple categories that are set in advance according to the user's psychological situation estimated from the user's utterance content and the user's environment estimated from objective information such as season, time, and weather. There has been proposed a music playback device that selects (frustrated, tired, fun, etc.) and searches music data belonging to the selected category from a music database for playback (see Patent Document 2).

  A server computer connected to the user terminal via a network reads out music corresponding to music selection information (music tempo, age, genre, etc.) input from the user terminal from the database device, and creates a playlist based on the music selection information. An automatic music selection system that is created and transmitted to a user terminal together with music data has been proposed (see Patent Document 3).

  Alternatively, the index number, date, etc. of the song played by the LD player used in karaoke are recorded on the optical card as history data, and the history data is read from the optical card when playing the song. A music playback device has been proposed in which a song that has been played back or a song that has been played back in sequence is displayed in order so that the song can be selected quickly according to the user's tendency (see Patent Document 4).

Furthermore, when performing random playback in which music is randomly selected and played back, an audio playback device that selects music based on a coefficient indicating “ease of selection” set by the user according to preference (Patent Document) 5), information for specifying music data of a music piece that has been played back and skipped to the beginning of the next music piece to be played, and the media (CD or MD) on which the music piece is recorded TOC (Table Of Contents) information is stored in pairs, and the next time the media is played, the skipped music is automatically selected based on the information that specifies the music data of the skipped music. There has been proposed a media playback device that skips the playback of the media (see Patent Document 6). Depending on the issue, the music data
JP 2005-135519 A JP 2006-092430 A JP 2002-073041 A JP-A-8-031150 JP-A-9-330586 JP 2002-184158 A

  By the way, as mentioned above in the description of the prior art, the music playback device has an evaluation value numerically representing the user's preference in order to play the song according to the user's preference without taking time and effort. Some have a function of creating a playlist according to the evaluation value that is set for each evaluation. According to this function, it is possible to reproduce music that reflects the subjective evaluation of the user. It is also a very useful function that is expected to have a secondary effect of expressing the user's feelings about music. However, on the other hand, there is a problem that the setting of the evaluation value has to be relied on manually input by the user, which is bothersome as in the case of music selection.

  The present invention has been made in view of the above problems, and provides a music playback device capable of setting and changing evaluation values representing user preferences without bothering the user and a camera equipped with the same. The purpose is to do.

  In order to achieve the above object, the invention described in claim 1 is characterized in that a playback means for playing back and outputting music, rewind playback to the beginning of the currently played music, and music to be played next An operation input means for causing the playback means to perform fast-forward playback that skips to the beginning of the sound, and a first evaluation value that represents a user's preference for the music is changed according to an operation input signal from the operation input means First setting change means and first storage means for storing the first evaluation value, the first setting change means raises the first evaluation value when the rewind reproduction is executed, When the fast forward reproduction is executed, the first evaluation value is lowered.

  Preferably, the first setting change means does not change the setting when the rewind playback or the fast forward playback is executed in a preset period from the beginning or end of the music.

  Preferably, the first setting change means changes the degree of the setting change according to the playback position of the music on which the rewind playback or the fast forward playback is executed.

  The first setting change means preferably changes the setting of the first evaluation value according to the number of times the music has been played.

  A second setting changing means for changing a setting of a second evaluation value representing a user's preference for the artist of the music, and a second storage means for storing the second evaluation value in response to the setting change of the first evaluation value; It is preferable to provide. In this case, it is preferable that the second setting change unit changes the setting of the second evaluation value with a degree of setting change lower than the first evaluation value.

  A seventh aspect of the present invention is a camera, wherein the music playback device according to any one of the first to sixth aspects is mounted.

  According to the music playback device and the camera equipped with the music playback device of the present invention, when the rewind playback is executed to return to the beginning of the currently played music, the first evaluation value representing the user's preference for the music is increased. When fast-forward playback that skips to the beginning of the next song to be played is performed, the evaluation value is lowered so that the user does not have to perform an operation to set the evaluation value. The evaluation value can be automatically changed only by performing a normal reproduction operation.

  In FIG. 1, a portable audio player (hereinafter simply referred to as an audio player) 2 as a music playback device includes a substantially rectangular main body 2a. On the front surface of the main body 2a, a liquid crystal display (hereinafter abbreviated as LCD) 10 and an operation unit 11 for displaying a list of artists and music, a reproduction status of music, various setting screens, and the like are provided. Further, a lock / release switch 12 for switching the operation of the operation unit 11 to invalid / valid and an earphone jack 14 (see FIG. 2) into which the connector terminal 13a of the earphone 13 is inserted and removed are provided on the upper surface of the main body 2a. It has been.

  The operation unit 11 includes a click wheel 15 formed in an annular shape, and a determination button 16 that is arranged at the center of the ring of the click wheel 15 and is pressed when determining the selection contents. By touching the click wheel 15 with a finger, it is possible to scroll through a list of artists and music displayed on the LCD 10 and a list of setting items on various setting screens.

  By pressing the corresponding portions 15a to 15d of the click wheel 15 corresponding to the vertical and horizontal directions of the main body 2a, transition of various screens displayed on the LCD 10 (15a), playback / stop of music (15b), and current playback, respectively. It is possible to perform rewind playback (15c) to return to the beginning of the music being played and fast forward playback (15d) to skip to the beginning of the music that is scheduled to be played next. In the following description, the corresponding portions 15a to 15d are referred to as a screen transition switch, a play / stop switch, a rewind switch, and a fast forward switch, respectively. The click wheel 15 has, for example, a configuration in which mesh-like electrodes face each other with a predetermined interval in the vertical and horizontal directions of the main body 2a.

  In FIG. 2 showing the electrical configuration of the audio player 2, the CPU 20 controls the overall operation of the audio player 2. A signal processing unit 22, a memory 23, a hard disk drive (hereinafter abbreviated as HDD) 24, an LCD driver 25, and a first setting change unit 26 are connected to the CPU 20 via the bus 21 together with the operation unit 11 described above. Has been.

  The signal processing unit 22 includes a D / A converter (hereinafter abbreviated as D / A) 22a and an amplifier (hereinafter abbreviated as AMP) 22b. The D / A 22a converts the digital music data into analog data and outputs it to the AMP 22b. The AMP 22b amplifies the analog music data from the D / A 22a with a predetermined amplification factor and outputs the amplified data to the earphone jack 14. Thereby, sound waves based on the music data are output from the earphone 13 connected to the earphone jack 14.

  The HDD 24 stores various programs for operating the audio player 2 and music data. The CPU 20 reads a program from the HDD 24 and develops it in the memory 23, sequentially processes the read program, reads out music data from the HDD 24, temporarily stores it in the memory 23, and outputs it to the signal processing unit 22.

  The CPU 20 operates each unit of the audio player 2 in accordance with an operation input signal input from the operation unit 11. For example, by detecting an electrical signal such as a change in capacitance or current between the electrodes constituting the click wheel 15, the contact position, rotation direction, and rotation speed of the finger are detected, and the detection results thereof Accordingly, the LCD driver 25 is controlled to change the scroll direction and speed of the list on the display screen of the LCD 10.

  The music data stored in the HDD 24 is acquired from, for example, a CD, MD, or the Internet via a data input / output I / F (not shown). The HDD 24 includes not only music data but also information on the album in which the music data is recorded (title, artist name, number of songs recorded in the album, total performance time, label, date released, etc.), music Information on the music represented by the data (song name, performance time, genre, image, etc.) is also stored. The HDD 24 stores music data organized by artist and album based on these pieces of information. Note that information on albums and songs is stored in advance on CDs and MDs, or publicly available on the music information providing server on the Internet, so these information are automatically read out when obtaining music data. , And can be stored in the HDD 24.

  Further, the HDD 24 stores a first evaluation value that represents a user's preference for music in association with music data. The first evaluation value can be set in, for example, 10 levels from 1 to 10, and the larger the numerical value, the more the user represents the music. The first evaluation value is set to an intermediate “5” by default.

  As schematically shown in FIG. 3, when the rewind switch 15 c is operated during playback of music and the rewind playback is executed, the first setting change unit 26 selects the music (in this case, music A). The first evaluation value corresponding to the music data is increased by one level. In addition, when the fast-forward switch 15d is operated during the reproduction of the music and the fast-forward reproduction is executed, the first setting changing unit 26 sets the first evaluation value corresponding to the music data of the music (in this case, the music C). Move down one step. In addition, the vertical bar | burr which divides music A-C shows the performance start and end position of each music A-C, and the lower arrow shows the direction in which music A-C is reproduced | regenerated in order. Also, the point on the horizontal bar indicates the playback position of the music for which rewind playback or fast forward playback has been executed.

  As shown in FIG. 4, the first setting changing unit 26 performs a rewind playback or fast forward playback for a preset period from the beginning or end of a song (in this case, song B), for example, 10 seconds. If it is executed within, the setting of the first evaluation value is not changed. Note that the first setting change unit 26 detects a period of 10 seconds from the beginning or the end of the music by monitoring the playback time of the music while checking the performance time of the music stored in the HDD 24, for example. . Needless to say, in contrast to the example shown in FIG. 4, when fast-forward playback or rewind playback is executed within 10 seconds from the beginning or end of the music, the first setting change unit 26 As in the example shown in FIG. 3, the first evaluation value is changed.

  Next, the operation of the audio player 2 having the above configuration will be described with reference to the flowchart of FIG. First, the user operates the click wheel 15 while viewing a list displayed on the LCD 10 to select a music piece to be reproduced. Then, the reproduction / pause switch 15b is operated to start reproduction of the music.

  When the reproduction of the music is instructed, the music data of the corresponding music is read from the HDD 24 to the CPU 20. The music data read by the CPU 20 is temporarily stored in the memory 23 and output to the D / A 22a via the CPU 20. In the D / A 22a, D / A conversion is performed on digital music data. The analog music data D / A converted by the D / A 22a is amplified by the AMP 22b and then outputted as sound waves from the earphone 13 via the earphone jack 14.

  In FIG. 5, when the rewind switch 15c or fast-forward switch 15d is operated during music reproduction, the CPU 20 receives an operation input signal from the rewind switch 15c or fast-forward switch 15d, and the CPU 20 performs rewind reproduction or fast-forward. Playback is executed. That is, the playback is performed by returning to the head of the currently played music, or the playback is skipped to the head of the music that is scheduled to be played next.

  When rewind playback or fast forward playback is performed and the operation position is not within 10 seconds from the beginning or end of the song, the first evaluation value corresponding to the music data of the song is the first setting change unit 26. Is raised or lowered by one step. This frees the user from bothering to set the first evaluation value, and can obtain the first evaluation value that appropriately reflects the user's preferences.

  On the other hand, when the rewind playback or fast forward playback operation position is within 10 seconds from the beginning or end of the music, the first evaluation value setting is not changed. In this way, it is possible to cope with the case where it is desired to execute rewind reproduction or fast forward reproduction but does not want to change the setting of the first evaluation value.

  The above-described series of processing is repeatedly executed until the reproduction / stop switch 15b is operated to stop reproduction or all the music to be reproduced is reproduced. Using the first evaluation value thus changed, for example, a playlist in which only songs having a high first evaluation value are collected and reproduced, or songs having a low first evaluation value are collected from the HDD 24. And can be deleted.

  In the above embodiment, the setting change of the first evaluation value is uniformly raised or lowered by one step. However, even if the degree of setting change is changed according to the operation position of rewind playback or fast forward playback. Good.

  For example, if the playback start position of the music is 0% and the end position is 100%, the rewind playback operation position is 0 to 25% of the music playback time (when rewind playback is executed within 10 seconds from the beginning) When the first evaluation value setting is not changed, the first evaluation value is increased by 0.5 when the position of the period excluding 10 seconds from the head is reached, and 1 is set at the position of 26 to 50%. Steps are raised by 2 steps at positions 51 to 75%, and 3 steps by 76 to 100%.

  In addition, when the fast-forward playback operation position is at a position of 0 to 25% of the music playback time, the first evaluation value is lowered by three stages, and at a position of 26 to 50%, two stages, 51 to 75% positions. In step 1, 76 to 100% (if fast-forward playback is executed within 10 seconds from the end, if the first evaluation value setting is not changed, the period excluding 10 seconds from the end) is 0.5. Decrease each stage. Or, more simply, when fast-forward playback is executed within 10 seconds from the beginning of the music, the first evaluation value may be lowered by three stages, and may be lowered by two stages between 10 seconds and 1 minute. In this way, user preferences can be reflected more. Note that, as a method of specifying the music playback position, the music playback time is monitored while collating with the music performance time stored in the HDD 24 as in the above embodiment.

  In addition to changing the setting of the first evaluation value by executing rewind playback or fast-forward playback, the setting may be changed according to the number of times the music has been played. In this case, as shown in the flowchart of FIG. 6, when the music is played to the end without performing rewind playback or fast-forward playback, the first evaluation value is increased by one step. As a result, it is possible to change the setting of the first evaluation value even for a user who has a low execution frequency of rewind playback or fast-forward playback.

  In the above embodiment, an example of setting and changing the first evaluation value indicating the user's preference for music has been described, but in addition to this, the user's preference for an artist can be set as in the audio player 30 shown in FIG. You may provide the 2nd setting change part 31 which changes the setting of the 2nd evaluation value to represent.

  As in the case of the first evaluation value, the second evaluation value is stored in the HDD 24 in association with the music data, and can be set, for example, in 10 steps from 1 to 10. The larger the numerical value, the more the user Shows that he likes the artist. The second evaluation value is set to an intermediate “5” by default. The first evaluation value is different for each music data. However, since the second evaluation value corresponds one-to-one for each artist, the value stored for the music data of the same artist is: The same is true.

  Similar to the first setting change unit 26, the second setting change unit 31 increases the second evaluation value corresponding to the artist of the music and performs fast-forward playback when the rewind playback is executed during the music playback. If so, the second evaluation value corresponding to the artist of the song is lowered. In this way, as in the case of the first evaluation value, a playlist in which only artists with a high second evaluation value are collected and reproduced, or albums of artists with a low second evaluation value are collected together on the HDD 24. And the convenience to the user can be further enhanced.

  Here, depending on the artist, a relatively large number of music data may be stored. For such artists, if the second evaluation value is set and changed to the same degree as the first evaluation value, the variation in the second evaluation value will be too large compared to an artist with little music data, and the user's preference will be increased. It cannot be expressed properly. For this reason, the second setting change unit 31 moves the first evaluation value up and down by one step in the first setting change unit 26, whereas the degree of setting change lower than the first evaluation value, for example, 1/10 Change the setting of the second evaluation value in step 0.1.

  In addition, although the 1st setting change part 26 and the 2nd setting change part 31 were provided separately, you may integrate these processes and carry out with one setting change part. Similarly to the case of the first setting change unit 26, when the rewind playback or fast forward playback is executed in a preset period from the beginning or end of the music, the second setting change unit 31 The setting change of the second evaluation value may not be performed, or the setting change degree of the second evaluation value may be changed according to the operation position of the rewind playback or fast forward playback. Or you may change the setting of a 2nd evaluation value according to the frequency | count of reproducing | regenerating a music.

  In the above embodiment, the audio player 2 has been described as an example of a music playback device. However, the present invention is not limited to this, and for example, an on-vehicle vehicle that uses an HDD of a car navigation system as means for storing music data. The present invention may be applied to a conventional audio player, a stationary home audio component, a personal computer, or a camera such as the digital camera 40 shown in FIGS.

  8 and 9, the digital camera 40 has a substantially rectangular camera body 40a. A lens barrel 42 for holding the imaging lens 41 is provided on the front surface of the camera body 40a. On the upper surface, a release button 43 and an annular mode dial 44 surrounding the periphery are provided. In addition, an openable / closable lid 45 and an earphone jack 46 into which the connector terminal 13a of the earphone 13 is inserted and removed are provided on one side of the camera body 40a. When the lid 45 is opened, the memory card slot 48 into which the memory card 47 is detachably loaded is exposed.

  A liquid crystal display (hereinafter abbreviated as LCD) 49, an operation unit 50, and the like are provided on the back surface of the camera body 40a. The LCD 49 displays an image read from the memory card 47, a through image, and various setting screens related to shooting. In addition, the LCD 49 displays a list of artists and music, the reproduction status of music, and various setting screens related to music reproduction, like the LCD 10 of the above embodiment. The operation unit 50 includes a determination button 51 that is operated when a setting screen is displayed on the LCD 49 or when a selection content is determined, and a cross key 52 for moving the cursor within the setting screen.

  The cross key 52 corresponds to the click wheel 15 of the above embodiment. In other words, by pressing the corresponding portions 52a to 52d corresponding to the up / down / left / right directions of the camera body 40a, transition of various screens displayed on the LCD 49 (52a), playback / stop of music (52b), and current playback are performed. It is possible to perform rewind playback (52c) to return to the beginning of the music being played and fast forward playback (52d) to skip to the beginning of the music that is scheduled to be played next. In the following description, the corresponding portions 52a to 52d are referred to as a screen transition switch, a play / stop switch, a rewind switch, and a fast forward switch, respectively, as in the above embodiment.

  When the release button 43 is pressed after the framing of the subject by the optical viewfinder or the LCD 49, one shooting is performed. When the mode dial 44 is rotated, a still image shooting mode for shooting still images, a movie shooting mode for shooting movies, an image playback mode for displaying captured images on the LCD 49, and a music playback mode for playing back music , And setting modes for performing various settings are selectively switched.

  In FIG. 10, a CCD 60 is disposed behind the imaging lens 41. The CCD 60 photoelectrically converts a subject image that has passed through the lens group and formed on the imaging surface, and outputs an imaging signal. A CCD driver 62 controlled by the CPU 61 is connected to the CCD 60. The CCD driver 62 outputs a timing signal (clock pulse) for controlling the charge accumulation time and charge sweep timing of the CCD 60 to the CCD 60.

  The imaging signal output from the CCD 60 is input to the analog signal processing unit 63. The analog signal processing unit 63 performs correlated double sampling on the imaging signal, and outputs R, G, and B image signals that accurately correspond to the accumulated charge amount of each cell of the CCD 60. Then, the image signal is amplified at a predetermined amplification factor and output to an A / D converter (hereinafter abbreviated as A / D) 64.

  The A / D 64 performs A / D conversion on the image signal and outputs digital image data. The image data output from the A / D 64 is input to the SDRAM 66 via the data bus 65 and is temporarily stored in the SDRAM 66. The analog signal processing unit 63 and the A / D 64 are synchronously driven in accordance with a timing signal input from a timing generator (not shown), and output image data at a constant frame rate.

  The digital signal processing unit 67 reads image data from the SDRAM 66 and performs various image processing such as gradation conversion, white balance correction, and γ correction on the image data. The image data that has been subjected to image processing by the digital signal processing unit 67 is stored again in the SDRAM 66.

  The YC conversion processing unit 68 reads the image data from the SDRAM 66, and performs YC conversion for converting the RGB signal into the luminance signal Y and the color difference signals Cr and Cb. The compression / decompression processing unit 69 performs image compression in a predetermined compression format (for example, JPEG format) on the image data that has been subjected to full-scale YC conversion by the YC conversion processing unit 68. The image data compressed by the compression / decompression processing unit 69 is stored again in the SDRAM 66.

  The memory control unit 70 reads the compressed image data from the SDRAM 66 and records it in the memory card 47. The image data recorded in the memory card 47 is temporarily stored in the SDRAM 66 via the memory control unit 70, read out to the compression / decompression processing unit 69, and decompressed to the image data before being compressed.

  Similar to the HDD 24 of the above embodiment, the memory card 47 stores music data, information on the album in which the music data is recorded, and music information represented by the music data. Music data is stored organized by artist and album. The memory card 47 stores the first evaluation value in association with the music data.

  Connected to the LCD driver 71 is a VRAM (not shown) in which image data for two frames subjected to simple YC conversion by the YC conversion processing unit 68 is stored. The VRAM performs writing and reading of image data in parallel. The LCD driver 71 converts the image data read from the VRAM into an analog composite signal, and displays it on the LCD 49 as a through image. The LCD driver 71 displays the image data expanded by the compression / decompression processing unit 69 on the LCD 49 as a reproduced image.

  The signal processing unit 72 corresponds to the signal processing unit 22 of the above-described embodiment, and includes a D / A that converts digital music data into analog and an AMP that amplifies analog music data from the D / A. Analog music data amplified by the AMP is output as sound waves from the earphone 13 via the earphone jack 46.

  The first setting change unit 73 corresponds to the first setting change unit 26 of the above-described embodiment. When the rewind switch 52c is operated during the reproduction of the music and the rewind reproduction is executed, the first setting change unit 73 adds the music data of the music. When the corresponding first evaluation value is increased by one level and the fast forward switch 52d is operated during the reproduction of the music and the fast forward reproduction is executed, the first evaluation value corresponding to the music data of the music is decreased by one level. The first setting change unit 26 sets the first evaluation value when the rewind playback or fast forward playback is executed within a preset period from the beginning or end of the music, for example, within 10 seconds. Do not make any changes.

  The CPU 61 transmits a control signal to each unit via the control bus 74, receives a response signal from each unit, and comprehensively controls the operation of each unit. In addition to the release button 43 and the operation unit 50, the CPU 61 is connected to an EEPROM 75 in which various control programs and setting information are recorded. The CPU 61 receives a release signal from the release button 43 and causes each unit to execute a process associated therewith. Further, the CPU 61 operates each unit according to an operation input signal input from the operation unit 50, reads various information from the EEPROM 75 to the built-in RAM, and executes processing.

  Next, the operation of the digital camera 40 having the above configuration will be described. When taking a still image with the digital camera 40, the digital camera 40 is turned on and the mode dial 44 is operated to select a still image shooting mode.

  In the still image shooting mode, a subject image incident through the imaging lens 41 is formed on the imaging surface of the CCD 60, and thereby an imaging signal is output from the CCD 60. The imaging signal output from the CCD 60 is correlated double sampled and amplified by the analog signal processing unit 63, and converted to digital image data by the A / D 64.

  The image data digitized by the A / D 64 is input to the SDRAM 66 through the data bus 65 and is temporarily stored in the SDRAM 66. The image data stored in the SDRAM 66 is subjected to simple YC conversion by the YC conversion processing unit 68 and then stored in the VRAM. The image data stored in the VRAM is sequentially read out by the LCD driver 71, converted into a composite signal by the LCD driver 71, and displayed on the LCD 49 as a through image.

  When shooting is executed by pressing the release button 43 while a through image is displayed, the image data obtained at this time is stored in the SDRAM 66. The image data stored in the SDRAM 66 is subjected to full-scale YC conversion by the YC conversion processing unit 68 and then compressed by the compression / decompression processing unit 69 and stored in the SDRAM 66 again. The compressed image data stored in the SDRAM 66 is read to the memory control unit 70 and recorded on the memory card 47 under the control of the memory control unit 70.

  When the mode dial 44 is operated to select the image reproduction mode, the image data recorded on the memory card 47 is stored in the SDRAM 66. Then, the image data is read from the SDRAM 66 to the compression / decompression processing unit 69, decompressed by the compression / decompression processing unit 69, becomes the original image data, and is stored again in the SDRAM 66. The decompressed image data stored in the SDRAM 66 is read by the LCD driver 71 and reproduced and displayed on the LCD 50.

  Further, when the mode dial 44 is operated to select the music playback mode and the playback of music is instructed, the music data of the corresponding music is read from the memory card 47 to the CPU 61. The music data read by the CPU 61 is temporarily stored in the SDRAM 66 and output to the signal processing unit 72 via the CPU 61. In the signal processing unit 72, D / A conversion is performed on the digital music data by D / A to obtain analog music data, which is then amplified by AMP. Analog music data amplified by the AMP is output as sound waves from the earphone 13 via the earphone jack 46.

  When the rewind switch 52c or the fast forward switch 52d is operated during the reproduction of the music, the CPU 61 receives the operation input signal from the rewind switch 52c or the fast forward switch 52d, and the CPU 61 executes the rewind reproduction or the fast forward reproduction. The

  When rewind playback or fast forward playback is performed and the operation position is not within 10 seconds from the beginning or end of the music, the first evaluation value corresponding to the music data of the music is the first setting change unit 73. Is raised or lowered by one step. On the other hand, when the rewind playback or fast forward playback operation position is within 10 seconds from the beginning or end of the music, the first evaluation value setting is not changed. The above-described series of processing is repeatedly executed until the reproduction / stop switch 52b is operated to stop the reproduction or all the music to be reproduced is reproduced.

  As in the case of the first setting change unit 26, the degree of setting change of the first evaluation value may be changed according to the operation position of rewind playback or fast forward playback. Or you may change the setting of a 1st evaluation value according to the frequency | count of reproducing | regenerating a music. Further, like the audio player 30, a second setting changing unit for changing the setting of the second evaluation value indicating the user's preference for the artist may be provided.

  Although the digital camera 40 has been described as an example of the camera, the present invention is not limited to this, and may be applied to other cameras such as a camera-equipped mobile phone, a silver salt camera, and a lens-fitted film unit. it can.

  In the above embodiment, the first and second evaluation values are stored in association with the music data. However, it is not always necessary to associate them, and the music data is classified and stored on the basis of the first and second evaluation values. Also good. Further, it may be configured to be able to select whether or not to change the setting of the first and second evaluation values in response to execution of rewind playback or fast forward playback. Furthermore, by pressing and holding the rewind switch or fast-forward switch, it is possible to rewind and fast-forward while playing the music. Depending on these operations, the first and second evaluation values are set. Settings may be changed.

  In the above-described embodiment, the music is reproduced and output by the earphone 13, but a headphone or a speaker may be used instead. In addition, as an operation input unit for executing rewind playback and fast forward playback, a switch having several functions such as the click wheel 15 and the cross key 52 is illustrated, but a single switch may be used. . Further, the HDD 24 and the memory card 47 have been described as examples of means for storing music data. However, the present invention is also applicable to a case where a flash memory or a removable recording medium replacing the memory card is used. is there.
