A one-chip microcomputer for controlling each part of the digital camera 1.
In particular, the CPU 9 has a function (acquisition means) for acquiring moving image data with sound recorded in the flash memory 13, a function for slow reproduction of moving image data of the acquired moving image data with sound (slow reproduction control means), A function for recognizing the sound of the sound data of the moving image data (sound recognizing means), a function for separating the sound data of the acquired moving image data with sound based on the sound recognized by the sound recognizing means (breaking means), A function (sound reproduction control means) is provided that outputs each divided audio data from a speaker in synchronization with moving image data that is played back slowly at a normal speed (single speed).
In addition, a function for setting the playback speed of the moving image data to be played back slowly (slow playback setting means) and a function for determining whether the set playback speed is slower than a predetermined speed (speed determination means) are also provided.

The key input unit 10 includes a plurality of operation keys such as a shutter button, a power on / off key, a mode switching key, a cross key, and a SET key, and outputs an operation signal corresponding to the user's key operation to the CPU 9.
The memory 11 stores a control program and necessary data necessary for the CPU 9 to control each unit, and the CPU 9 operates according to the program.

To the CPU 9. The CPU 9 sequentially stores the transmitted audio data in the buffer memory (DRAM 12), and records the stored audio data in the flash memory 13 in association with the captured moving image data. That is, moving image data with audio is recorded.
In addition, when reproducing a moving image with sound, the sound processing unit 15 outputs sound or the like based on sound data recorded in association with the moving image data from the built-in speaker in accordance with the moving image data reproduced and displayed on the image display unit 14. Sounds out.

B. Operation of Digital Camera 1 The operation of the digital camera 1 in the embodiment will be described with reference to the flowchart of FIG. In the present embodiment, description will be made on the assumption that moving image data is played back slowly.
When an instruction to reproduce the moving image data with audio is given by the user's operation of the key input unit 10, the CPU 9 out of the moving image data with audio recorded in the flash memory 13 in step S 1. The moving image data with sound instructed to be reproduced by the operation (moving image data and sound data associated with the moving image data) is acquired by reading from the flash memory 13 (acquiring means). The read moving image data with sound is stored in the buffer memory (DRAM 12).

Next, in step S2, it is determined whether or not the currently set moving image playback speed is slower than a predetermined speed (speed determination means).
The user can arbitrarily select a moving image playback speed in advance in the setting mode or the menu mode by operating the key input unit 10, and the CPU 9 sets the selected playback speed as the moving image playback speed. (Slow playback speed setting means). That is, the CPU 9 records the reproduction speed selected by the user in the reproduction speed recording area of the memory 11. The user can set a playback speed of less than 1 × speed, such as 1 × speed (normal speed), 1/2 × speed, 1/3 × speed, and 1/4 × speed. Here, the playback speed set by the user is set to 1/3 speed, and the predetermined speed is set to 1/2 speed.

When it is determined in step S2 that the set playback speed (the playback speed recorded in the playback speed recording area) is slower than the predetermined speed recorded in advance in the memory 11, the process proceeds to step S3, and the CPU 9 acquires the acquisition speed. The voice data of the moving image data with voice stored in the buffer memory is recognized by voice recognition processing (voice recognition means).
Although the story changes here, as shown in Fig. 3 (a), the acquired moving image data with audio has a recording time of 8 seconds with the audio data recorded, and the recorded audio is "Initiate, Yay, □□ Start , Wah, Wah ".

Of these “Ichini Itai, Yoi, □□ Start, War, War”, the voice “Ichini” is recorded from 0 seconds to 1 second, and the voice “Twitte” is recorded from 1 second to 2 seconds. The sound “-” was recorded between 2 and 3 seconds, the sound “Yoi” was recorded between 3 and 4 seconds, and no sound was recorded between 4 and 5 seconds ( □□ part), “Start” sound is recorded between 5 and 6 seconds, the first “War” sound is recorded between 6 and 7 seconds, and the second “War” is called Audio is recorded between 7 and 8 seconds.
Returning to the speech recognition process, the speech recognition process here recognizes words based on the speech, thereby recognizing portions (for example, phrases) that are well-delimited by the sentence of the words. Since this voice recognition process is already a well-known technique, a description thereof will be omitted. As a result, it is possible to make it easy to hear the voice sentence to be emitted without dividing the sentence at a bad place.

  Next, in step S4, the CPU 9 divides the voice data into a plurality of parts (separating means) based on the voice recognition processing. For example, if the voice recognized as a good segment by voice recognition is "Ichiniti," "Yoi," "□□," "Start," "War," or "Wor", all recorded voices The data consists of voice data for “Initiate” (voice data for 0 to 3 seconds), voice data for “Yoi” (voice data for 3 to 4 seconds), and voice data for “□□” (4 Audio data for seconds to 5 seconds), that is, audio data for a portion without sound, “start” audio data (audio data for 5 seconds to 6 seconds), and first “war” audio data ( Audio data from 6 seconds to 7 seconds) and second “War” audio data (audio data from 7 seconds to 8 seconds).

Next, in step S5, the CPU 9 reproduces the moving image data of the acquired moving image data with audio (stored in the buffer memory) at the set reproduction speed (reproduction speed recorded in the reproduction speed recording area). Start (slow playback control means).
That is, the frame data of the moving image data is sequentially displayed on the image display unit 14 from the beginning at the set reproduction speed. The playback at the set playback speed is, for example, when the video data of the video data with audio is captured at a frame rate of 1/30 seconds, and the playback speed set is 1/3 times faster. In this case, display is performed at a frame rate interval of 1/10 second, that is, at an interval for displaying 10 frame data per second.

When the reproduction of the moving image data is started, the CPU 9 starts an operation of reproducing the divided audio data at a normal speed while synchronizing with the reproduced moving image data (audio reproduction control means). Thereby, it is possible to make it easy to hear the voice of the voice data.
Specifically, when the reproduction of the moving image data is started, the CPU 9 first starts the reproduction of the first divided audio data among the plurality of divided audio data at a normal reproduction speed (1 × speed). (Step S6).
Here, among the audio data divided into a plurality of pieces, the first divided audio data is “Initiate” audio data, and therefore an operation of reproducing the audio data at a normal reproduction speed is started. This normal playback speed is the same speed (actual speed) as the speed of the voice when recording.
The reproduced sound is emitted from the built-in speaker of the sound processing unit 15.

Next, the CPU 9 determines whether or not the reproduction of the audio data has been completed (step S7). For example, in the case where the audio data of “Infinite” is being reproduced, it is determined whether or not it has been reproduced to the end.
If it is determined in step S7 that the reproduction of the audio data has not ended, the process stays in step S7 until the end, and if it is determined that the reproduction of the audio data has ended, the CPU 9 determines the moving image data corresponding to the divided audio data. It is determined whether or not the reproduction is finished (step S8). The moving image data corresponding to the divided audio data is, for example, 0 seconds because the audio data is audio data from 0 seconds to 3 seconds when the classified audio data is “initialize”. This means that the video data corresponds to up to 3 seconds, and in the case of video data shot at a frame rate of 1/30 seconds, the playback of the video data of the first to 90th frames has been completed. It will be whether or not. Also, if the segmented audio data being played is “Yoy”, the audio data is audio data from 3 seconds to 4 seconds, so it is video data corresponding to 3 seconds to 4 seconds. In the case of moving image data shot at a frame rate of 1/30 seconds, it means whether or not the reproduction of moving image data of the 91st to 120th frames has been completed.

If it is determined in step S8 that the reproduction of the moving image data corresponding to the divided audio data being reproduced has not been completed, the process remains in step S8 until it is determined that the reproduction has been completed. At this time, since the reproduction of the divided audio data has been completed, no audio is emitted from the speaker of the audio processing unit 15, that is, a silent state is entered.
On the other hand, when it is determined in step S8 that the reproduction of the moving image data corresponding to the divided audio data being reproduced has ended, the CPU 9 determines whether or not the reproduction of the moving image has ended (step S9). That is, the determination is made based on whether or not the frames of moving image data have been reproduced to the end.

If it is determined in step S9 that the reproduction of the moving image data has not ended, the CPU 9 reproduces the divided audio data next to the divided audio data that has been reproduced among the plurality of audio data. Is started at a normal reproduction speed (step S10), and the process returns to step S7. For example, in the case where the sound data “Initiate” has been reproduced, the reproduction of the sound data “Yoy” is started. That is, the audio data divided into a plurality of pieces is reproduced at a normal reproduction speed in synchronization with the moving image data corresponding to each divided audio data.
The reproduced sound is emitted from the built-in speaker of the sound processing unit 15.

FIG. 3B shows the state of the video and audio reproduced in the embodiment.
The recorded video data time is 8 seconds, and the set playback speed is 1/3 times the speed, so when 3 seconds have elapsed, playback of the video data for 1 second is completed, and when 6 seconds have elapsed, 2 seconds. It can be seen that the reproduction time of the moving image data takes three times as much as the actual recording time so that the reproduction of the moving image data of the minute ends.

  In addition, among the audio data divided into a plurality of pieces, the first video data is “Initiate”, and this portion of the audio is recorded for 0 to 3 seconds. Since the video data is played back at a speed, the video data corresponding to the divided audio data (video data recorded during 0 to 3 seconds) is played back during 0 to 1 second. At the point of time, the reproduction of the divided audio data ends. Therefore, a waiting operation is performed until the reproduction of the moving image data corresponding to the divided audio data is completed, that is, when the reproduction of the moving image data corresponding to the divided audio data is completed. The reproduction of the received voice data (here, the voice data recorded for 3 to 4 seconds), that is, the voice data of “Yoy” is started. That is, the divided audio data is reproduced at a normal reproduction speed in synchronization with the moving image data corresponding to the audio data. When the reproduction of the “Yoy” audio data is completed, a waiting process is performed until the reproduction of the moving image data (moving image data recorded for 3 to 4 seconds) corresponding to the divided audio data is completed. When the reproduction of the moving image data is completed, the reproduction of the next divided audio data is started.

On the other hand, if it is determined in step S2 that the playback speed of the set moving image is not slower than the predetermined speed, the CPU 9 plays back the moving image data and the audio data of the acquired moving image data with audio. It starts at the speed (the playback speed recorded in the playback speed recording area) (step S11).
For example, when the set playback speed is 1 / 1.5 times speed, that is, 2/3 times speed, the playback of the movie data of the movie data with audio starts at 2/3 times speed, and the Playback of audio data is also started at 2/3 speed. That is, the reproduction of the conventional moving image data with sound is started.
The reproduced sound is emitted from the built-in speaker of the sound processing unit 15.
This is because if the set playback speed is not slower than the predetermined speed, a sound that is difficult to hear even if the audio data is played back at the playback speed is emitted.
Next, the CPU 9 determines whether or not the moving image playback process has ended (step S12), and remains in step S12 until the end.

C. As described above, in the embodiment, when the set playback speed is slower than the predetermined speed, the audio data of the video data with audio is divided into a plurality of video data and the video data of the video data with audio is set. Since the audio data is played back at a normal playback speed in synchronization with the moving image data corresponding to the audio data, it is easy to hear from the built-in speaker. Sound can be emitted.
In addition, since the voice of the voice data is recognized by a voice recognition process, a portion where the sentence is well separated is recognized, and the voice data is divided based on the recognition, so that the sentence to be emitted can be easily heard.

[Modification]
D. The above embodiment may be the following modes.
(1) In the above embodiment, the position where the divided audio data and the moving image data corresponding to each audio data are synchronized is set to the start of reproduction of the divided audio data and the divided audio data. As shown in FIG. 3C, the segmented audio data is reproduced in the middle of the segmented video data corresponding to the segmented audio data. So that the middle of the segmented audio data and the middle of the moving image data corresponding to the segmented audio data are reproduced at the same time. Alternatively, the playback end of the segmented audio data and the end of playback of the moving image data corresponding to the segmented audio data may be the same.
Further, if the segmented audio data is reproduced during the reproduction of the moving image data corresponding to the segmented audio data (if the reproduction is started and ends), at any arbitrary timing You may make it reproduce. In other words, it may be played back at an arbitrary timing within the synchronized period.

(2) In the above embodiment, the voice data is divided into a plurality of pieces based on the voice recognition process. However, the voice data may be simply divided every predetermined unit time.
FIG. 4A is a diagram showing the state of the moving image and sound reproduced at that time.
As shown in the figure, the audio data is divided every predetermined unit time (here, 1 second), and each of the divided audio data is synchronized with the moving image data corresponding to the audio data (here, the division). Thus, it can be seen that the playback of the audio data thus reproduced and the start of the reproduction of the moving image data corresponding to the divided audio data are performed simultaneously.

Further, as described in the modification (1), the synchronization position may be a position where the middle of the divided audio data and the middle of the moving image data are reproduced simultaneously, or the divided audio data The end of the playback may be the same as the end of the playback of the moving image data corresponding to the divided audio data (see FIG. 4B).
Also, if the segmented audio data is played back during the playback of the video data of the segmented audio data (if playback starts and ends), it is played back at any arbitrary timing. You may do it.

  (3) In the above embodiment, when it is determined in step S7 that the playback of the segmented audio data has been completed, in step S8, the moving image data corresponding to the segmented audio data is reproduced. The waiting process is performed until the end, but repeat playback of the segmented audio data may be performed until the reproduction of the moving image data corresponding to the segmented audio data is completed.

The operation of the digital camera 1 at this time will be described with reference to the flowchart of FIG. Steps that perform the same operations as those in the flowchart of FIG. 2 are given the same step numbers.
When the reproduction of the first audio data among the audio data divided into a plurality of parts at step S6 in FIG. 2 is started at a normal reproduction speed, the process proceeds to step S7 in FIG. 5 to reproduce the divided audio data. It is determined whether or not the process has been completed, and the process remains in step S7 until it is determined that the process has been completed.

When it is determined in step S7 that the playback of the segmented audio data has been completed, the CPU 9 determines that the segmented audio data has been reproduced again before the reproduction of the moving image data corresponding to the reproduced segmented audio data is completed. It is determined whether or not the audio data can be reproduced (step S21).
For example, when the reproduction of the audio data “Initiate” is completed, the reproduction of the “Initiate” is again performed before the reproduction of the moving image data corresponding to the audio data “0” is completed. It is determined whether or not audio data can be reproduced.

If it is determined in step S21 that the reproduced segmented audio data can be reproduced again before the reproduction of the moving image data corresponding to the reproduced segmented audio data is completed, the CPU 9 performs the reproduction. An operation of replaying the classified audio data at a lower volume than the previous time and at a normal reproduction speed is started, and the process returns to step S7. Thereby, as the number of times of repetition increases, the volume of the sound that is played back repeatedly decreases gradually.
On the other hand, if it is determined in step S21 that the reproduced segmented audio data cannot be reproduced again before the reproduction of the moving image data corresponding to the reproduced segmented audio data is completed, the step of FIG. Proceed to S8.

FIG. 6 shows the state of the video and audio reproduced at this time.
As can be seen from the figure, the segmented audio data is repeatedly reproduced until the reproduction of the moving image data corresponding to the segmented audio data is completed.
Note that the volume of repeat playback is reduced according to the number of times of repeat playback, but conversely, the volume may be increased.
Also, the volume for repeat playback (the volume played after the second time) may be set to the same volume. In this case, the volume for repeat playback may be the same as the volume played for the first time, or may be reduced or increased.

  (4) In the above embodiment, the voice data of the video data with voice is a human voice (speaking voice), or other natural sounds (sounds of animals, car sounds, It may be determined by voice recognition whether or not the sound of the waves of the sea and the sound of trees fluttering by the wind, and the present invention may be performed when it is determined that the sound is a human voice. This is because it is difficult to hear a human voice when it is played slowly, but it is not difficult to hear a natural sound even if it is played slowly (you do not know what you are saying).

The operation of the digital camera 1 will be described with reference to the flowchart of FIG.
When the moving image data with sound is acquired in step S1 of FIG. 2, the process proceeds to step S51 of FIG. 7, and the CPU 9 recognizes the sound of the acquired sound data of the moving image data with sound by a sound recognition process. Here, the voice recognition process may be a process capable of recognizing whether or not the voice is a human voice.
Next, in step S52, the CPU 9 determines whether or not the voice of the voice data is a human voice based on the voice recognition process (determination means).
If it is determined in step S52 that it is a human voice, the process proceeds to step S2 or step S3 in FIG. 2, and if it is not a human voice, the process proceeds to step S11.

  (5) Further, in the above embodiment, when each divided audio data is reproduced, the beginning of reproduction of each divided audio data may be faded in, and the end of reproduction may be faded out. .

(6) In the above embodiment, if it is determined that the set playback speed (the playback speed recorded in the playback speed recording area) is lower than the predetermined speed, the audio data is converted to the normal playback speed. However, if the audio data playback speed is faster than the video data playback speed (the set playback speed), it may be played back at a speed slower than the normal playback speed. . In other words, any speed that is faster than the set playback speed may be used. This is because if the playback speed of the audio data is higher than the set playback speed, the voice is not so difficult to hear.
In this case, the user may arbitrarily select the reproduction speed of the audio data. At this time, the CPU 9 sets the reproduction speed of the audio data according to the selection (audio reproduction speed setting means).

  (7) In the above embodiment, audio data is played back at a normal playback speed when a predetermined condition is satisfied regardless of the user's intention. It may be possible to select whether or not the audio data is to be reproduced at (the reproduction speed recorded in the reproduction speed recording area) (selection means). In this case, if audio data is selected to be played back at the set playback speed (playback speed recorded in the playback speed recording area), the process proceeds to step S11 in FIG. 2, and the audio is played at the set playback speed. If it is selected not to reproduce the data, the process proceeds to step S2 or step S3 in FIG.

(8) In the above embodiment, the moving image playback speed is set in advance in the setting mode or the menu mode. However, the setting of the moving image playback speed can be changed even during the moving image playback. It may be. The reproduction speed whose setting has been changed is overwritten on the reproduction speed recording area of the memory 11 and recorded.
At this time, when the setting is changed, it is determined again whether or not the set reproduction speed is lower than a predetermined speed. If it is slow, the audio data from now on is reproduced at the normal reproduction speed (1 × speed).
