For example, change of at least one of the selected image data and music data so that the performance time of music included in the selected music data and the time required to display the image included in the selected image data are substantially the same. (Ie, selecting new image data or music data).

[0083] Power! Alternatively, the user may use the input unit 353 to specify the playback order of the images included in the image data. At this time, it may be configured such that one image is reproduced a plurality of times at different timings. Similarly, the user can specify the playback order of the music included in the music data.

In FIG. 2 again, after the time display, it is determined whether or not the power to change at least one of the selected image data and music data is controlled under the control of the CPU 351 (step S 106). In other words, whether or not the user gives an instruction to change at least one of the selected image data and music data, or the performance time of the music included in the selected music data and the selected image It is determined whether the CPU 351 is automatically instructed to change at least one of the image data and the music data so that the time required to display the image included in the data is approximately the same. .

[0085] Note that, in addition to or instead of the determination in step S106, the music playing time included in the selected music data is divided by the number of images included in the selected image data. The display time may be calculated and images may be displayed continuously at the calculated display time interval. Thereby, without changing the selected image data and music data, the display of the image included in the image data can be ended simultaneously with the end of the reproduction of the music included in the music data.

[0086] As a result of the determination in step S106, when it is determined that at least one of the selected image data and music data is to be changed (step S106: No), the process returns to step S101 and step S103, At least one of image data and music data is selected again.

On the other hand, if it is determined in step S 106 that at least one of the selected image data and music data is not to be changed (step S 106: Yes), then The image data and music data selected in step S101 and step S103 are acquired (step S107).

[0088] Subsequently, the obtained image data and music data are decoded by the operations of the image decoder 303 and the music decoder 304 (step S108).

[0089] Subsequently, the music feature included in the acquired music data is analyzed by the operation of the music analysis unit 310 (step S109). Specifically, the power of what kind of tempo of each music included in the music data (or the power showing what kind of tendency or distribution, the power of what kind of phrase each music has (Or what kind of tendency or distribution is shown), what kind of aspect the other musical features are (or what kind of tendency or distribution is showing) Is done.

[0090] Subsequently, the operation of the special effect processing unit 311 causes image data (specifically, image data) based on the characteristics of the music analyzed in step S109 (that is, the analysis result of the music data). The reproduction effect of the image included in the image is defined (step S110).

[0091] Specifically, for example, the display of the image included in the image data may be switched in accordance with the tempo of the music included in the music data. Specifically, for example, when displaying an image in accordance with a fast-tempo music, the image is switched in a relatively short time (in other words, the display time per image is shortened), When displaying images in time with music with a slow tempo, the images can be switched in a relatively long time (V, in other words, the display time per image becomes longer).

[0092] Further, for example, a display effect to be added to the image included in the image data in accordance with the tempo of the music included in the music data (for example, movement of the display position of the image, rotation of the image, change in luminance of the image) Or the color change time of the image) may be set. Specifically, for example, when displaying an image in time with fast-tempo music, the display effect time may be set short. That is, for example, in a relatively short time, the display position of the image may be moved, the image may be rotated, the brightness of the image may be changed, or the color of the image may be changed. On the other hand, when displaying an image in time with music with a slow tempo, the display effect time may be set longer. In other words, for example, in a relatively long time, the display position of the image is moved, the image is rotated, the brightness of the image is changed, or the color of the image is changed. It may be changed.

Alternatively, for example, the display of the image included in the image data may be switched in accordance with a music phrase included in the music data. Specifically, for example, the image display may be switched for each phrase, the image display may be switched for several phrases, or a plurality of images may be displayed for each phrase. .

Alternatively, for example, the display effect time to be added to the image included in the image data may be set in accordance with the music phrase included in the music data. Specifically, for example, for each phrase, the display position of the image may be moved, the image may be rotated, the brightness of the image may be changed, or the color of the image may be changed. For example, the display position of the image may be moved, the image may be rotated, the brightness of the image may be changed, or the color of the image may be changed every several phrases. Alternatively, for example, the display position of the image may be moved, the image may be rotated, the luminance of the image may be changed, or the color of the image may be changed based on the time of one phrase.

[0095] After that, by the operation of the reproduction unit 313, the image included in the acquired image data is reproduced while realizing the reproduction effect defined in step S110 in accordance with the reproduction of the music included in the acquired music data. Played (step S111). That is, the acquired image data and music data are reproduced as a slide show.

[0096] Subsequently, under the control of the CPU 351, it is determined whether there is image data or music data to be acquired next (in other words, to be newly acquired) and whether or not the data is powerful (step S11). 2). For example, when the image data is also acquired for each of the memory card 101 and the hard disk 102, the above-described processing is performed on the image data acquired from the memory card 101 first, and then the image data is acquired from the hard disk 102. The above-described processing is performed on the image data. The same applies to music data.

[0097] As a result of the determination in step S112, when it is determined that there is image data or music data to be acquired next (step S112: Yes), the process returns to step S107, and a new image is obtained. Data or music data is acquired, and the processing from step S108 onward is performed on the newly acquired image data or music data.

On the other hand, as a result of the determination in step S112, the next image data or music to be acquired If it is determined that there is no data (step S112: No), the processing from step S107 to step S111 is performed on all the image data and music data selected in steps S101 and S103. It turns out that it was broken. That is, it is found that all the image data and music data selected in steps S101 and S103 are reproduced as a slide show. Therefore, in this case, the reproduction operation is terminated.

As described above, according to the information recording / reproducing apparatus 200 of the present embodiment, the information recording / reproducing apparatus 200 is acquired while realizing the specified reproduction effect in accordance with the reproduction of the music included in the acquired music data. The image included in the received image data can be reproduced.

In particular, according to the present embodiment, it is possible to acquire each of desired recording medium force image data and music data among a plurality of recording media without limiting the data source to the same recording medium. In other words, the acquisition destination of each of the image data and the music data is not limited in advance. For this reason, the user can also obtain the desired data source for each of the music data and the image data. Therefore, a wider variety of slide shows can be played. In other words, a wide variety of images can be played back while realizing a wide variety of playback effects that are specified in accordance with the playback of a wider variety of music.

[0101] Furthermore, since the playback order of images can be freely specified, a slide show more suited to the user's preference can be played.

[0102] The characteristics of the acquired music data can be analyzed in real time (that is, every time the music data is acquired), and the reproduction effect of the image data can be defined according to the analysis result. In other words, since the playback mode of the image data played back together with the music data is not limited in advance, it is possible to enjoy the great advantage that the image data can be played back in accordance with the playback of the music data in a wider variety of modes. it can.

Note that the recording operation in the information recording / reproducing apparatus 200 according to the present embodiment has been described in the description of the block diagram of FIG. However, the recording operation is almost the same as the reproducing operation. Specifically, after the processing from step S101 to step S110 in FIG. 2 is performed, image data and music data are output from the special effect processing unit 311 to the encoder 312. Thereafter, the operation of the encoder 312 is performed. In step S11, play the music included in the acquired music data. On the other hand, the acquired image data and music data are encoded so that the image included in the acquired image data can be played back while realizing the playback effect specified in 0. The As a result, slide show data for playing the images included in the acquired image data is created while realizing the playback effect specified in step S110 in accordance with the playback of the music included in the acquired music data. Is done. As a result, the created slide show data can be recorded, for example, on the optical disc 103 or the like.

At this time, the image data and the music data are converted into a format of an optical disc 103 or the like (especially a DVD in this embodiment) on which slide show data created from the image data and music data is recorded, and the slide show It is preferable to record data on the optical disk 103. As a result, the slide show data can be played back on any device that can play back the optical disc 103 on which the slide show data is recorded. In other words, a special device for executing a dedicated program for performing a slide show using image data and music data without using a dedicated program for performing a slide show using image data and music data (for example, Slideshow data can be played relatively easily by using a player for the optical disc 103 that requires a computer or the like. Of course, when the slide show data is recorded on another recording medium, the same benefits can be obtained by performing the same operation.

Incidentally, according to the information recording / reproducing apparatus 200 of this embodiment, the recording operation and the reproducing operation are performed in parallel (that is, the slide show data for reproducing the slide show is generated while reproducing the slide show). And recording). At this time, the information recording / reproducing apparatus 200 according to the present embodiment includes reproduction buffers 121, 122, and 123 and recording buffers 131, 132, and 133, respectively. For this reason, if one recording medium capable of recording and reproducing operations at a speed of 2 × or higher is used, the reproduced image data can be reproduced while reproducing at least one of the recording medium power image data and music data. In addition, slide show data created by using at least one of music data and at least one of image data and music data recorded on another recording medium is recorded on one recording medium. [0106] The present invention is not limited to the above-described embodiments, but can be appropriately modified within the scope of the claims and the entire specification without departing from the gist or the idea of the invention which can be read.
