Abstract

Storage media containing still image data, dynamic image data and audio data in respective compression schemes are inserted into an insertion opening (21). When a replay button at an operation unit (10) is operated, a processing unit (31) reads data file with file number n from the storage media to check if the retrieved data file is still image data, dynamic image data or audio data and decompresses the data based on the decompression program conforming to that data. The still image data and dynamic image data decompressed by using the corresponding decompression programs are converted by a video decoder (34) and a video RAM (35) into image information and the audio data is converted by an A/D converter (36) into audio information for output from output terminals (22, 23). At this time, operating the feed button and return button at the operation unit (10) allows the file number n of the data file read from the storage media to be changed.

Also, as shown in the functional block diagram of Fig. 2, the playback device 1 has a processing unit (CPU) 31, ROM 32, RAM 33, video decoder 34, video ram 35, and DΖΑ (digital-to-analog) conversion. A container 36 and a built-in battery 37 are provided. The processing device (CPU) 31 converts audio data including still image data, moving image data, and music stored in the storage medium inserted into the insertion port 21 based on a compression method of each data. And decompress and perform data reproduction processing to reproduce image information and audio information. The ROM32 contains a still image data decompression program that decompresses still image data, video data, and audio data stored in the storage medium using the respective compression methods, such as the JPEG (Joint Photographic Expert Group) method. A program that decompresses still image data that is compressed and stored in, a video data decompression program, such as a program that decompresses video data that is compressed and stored in the MPEG (Moving Picture Expert Group) format, an audio data decompression program, such as ADPCM (Adaptive A program that decompresses audio data that has been compressed and stored using Differential Pulse Code Modulation), and a program that converts decompressed still image data and video data to image information A program for converting the decompressed audio data into audio information is stored.

RAM 32 is for temporarily storing the processing data. The video decoder 34 and the video ram 35 are for converting the decompressed still image data and the moving image data into image information for a display device. The 0 / oct converter 36 is for converting the decompressed audio data into audio information for an audio output device. The power for each component is supplied from an internal battery 37 or an external power supply connected to an external power supply terminal 24. Video Ram 35 and RAM 33 can be used together. The video decoder 34 and the 0/8 converter 36 can be configured by hardware or software. The processing means of the present invention includes a processing device 31, a video decoder 34, a video RAM 35, a DZA converter 36, and the like.

 The storage medium stores still image data, moving image data, and audio data for each data file, and each data file has an identification indicating the data type or data storage method of the data file. Information, an index indicating the title of the file, the date and time of shooting, and the like are stored. In some cases, the audio data may be stored together with the still image data or the moving image data.

 Next, the operation of the embodiment of the present invention will be described based on the flowchart of FIG. In the present embodiment, one data file selected by the user is repeatedly played.

 When the power button 11 is operated to turn on the power, it is determined whether or not a storage medium is inserted in the entrance 21 (step S l). Whether or not a storage medium is inserted into the entrance 21 is determined, for example, based on an output signal of a detection switch that is turned on when the storage medium is inserted into the entrance 21. (4) If it is determined that the storage medium is not inserted into the entrance 21, the process of step S 1 is repeated. On the other hand, if it is determined that the storage medium is inserted in the entrance 21, the file number n is set to 1 (step S 2).

Next, it is determined whether or not the play button 12 has been operated (step S3). Whether or not the playback button 12 has been operated is determined based on, for example, an output signal of a playback switch that is turned on when the playback button 12 is operated. If it is determined that the play button 12 has not been operated, the process of step S3 is repeated. On the other hand, if it is determined that the play button 12 has been operated, it is determined whether or not the data file with the file number n stored in the storage medium is still image data (step S4). Whether or not the data is still image data is determined based on, for example, the data type or data storage method included in the index of the data file. If it is determined that the file with the file number n is still image data, the still image data is reproduced (step S5). For example, the still image data compressed by the JPEG method is decompressed using a JPEG decompression program, and the decompressed still image data is converted into image information by the video decoder 34 and the video RAM 35. At this time, since audio data may be stored together with the still image data, the audio data reproduction process is also performed at the same time. It should be noted that an index indicating that the data is still image data and audio data may be stored in the data file, and the determination may be made based on the index.

 If it is determined in step S4 that the data file with the file number n is not a still image data, it is determined whether or not the data file is moving image data (step S6). Whether or not it is moving image data is determined based on, for example, the index of the data file. If it is determined that the data file with the file number n has moving image data, the moving image data is reproduced (step S7). For example, the video data compressed by the MPEG method is decompressed by using a MPEG decompression program, and the decompressed video data is converted into image information by the video decoder 34 and the video RAM 35. At this time, since the audio data may be stored together with the video data, the audio data reproduction process is also performed at the same time.

If it is determined in step S6 that the data file of the file number n is not a moving image file, it is determined whether or not the data is audio data (step S8). Whether the data is audio data is determined based on, for example, the index of the data file. If it is determined that the data file with the file number n is audio data, the audio data is reproduced (step S9). For example, audio data compressed by the ADPCM method is decompressed by the ADPCM decompression program, and the decompressed audio data is converted into audio information by the DZA converter 36. If the audio data is not compressed and stored, the audio data is supplied to the DZA converter 36 as it is and converted to audio information. I do.

 If it is determined in step S8 that the data file of file number n is not audio data, an error message such as "This card cannot be played." Is output to the output terminals 22 and 23. (Step S10). Then, it is determined whether or not the storage medium has been discharged from the inlet 21 (step S11). If it is determined that the storage medium has been ejected from the insertion slot 21, the process returns to step S1.

 If it is determined in step S11 that the storage medium has not been ejected from the insertion slot 21, it is determined whether the power button 11 has been operated and the power has been turned off (step S12). ). If it is determined that the power has not been turned off, the process returns to step S10 to continue outputting the error message. If it is determined that the power has been turned off, the processing ends.

 In step S5, step S7, and step S9, while performing the playback processing of still image data, the playback processing of video data, and the playback processing of audio data, It is determined whether or not the operation has been performed (step S13). Whether or not the feed button 13 has been operated is determined based on, for example, an output signal of an operation switch that is turned on when the feed button 13 is operated. If it is determined that the feed button 13 has been operated, 1 is added to the file number n (step S14), and the process returns to step S4. If the file number n is N, the number of data files stored in the storage medium, and N is a value obtained by adding 1 to the file number n, the file number transfer operation may be stopped at N. Alternatively, the value obtained by adding 1 to the file number n may be set to 1 so that the file transfer operation can be performed endlessly.

If it is determined that the feed button 13 has not been operated, it is determined whether or not the return button 14 has been operated (step S15). Whether or not the return button 14 has been operated is determined, for example, based on the output signal of the return switch that is turned on when the return button 14 is operated. If it is determined that the return button 14 has been operated, 1 is subtracted from the file number n (step S16), and the process returns to step S4. If the file number n is 1, the value obtained by subtracting 1 from the file number n may be set to 1 and the operation of returning the file number may be stopped at 1, or the value obtained by subtracting 1 from the file number n may be used. Number of data files stored on the storage medium The return operation may be performed to the endless.

 If it is determined that the return button 14 has not been operated, it is determined whether or not the stop button 15 has been operated (step S17). Whether or not the stop button 15 has been operated is determined, for example, based on an output signal of a stop switch that is turned on when the stop button 15 is operated. If it is determined that the stop button 15 has not been operated, the reproduction processing in steps S5, S7 and S9 is continued. The playback processing in steps S5, S7, and S9 operates in a one-file repetition playback mode in which, when playback to the end of the selected data file has been completed, the playback returns to the beginning and repeats playback.

 If it is determined in step S17 that the stop button has been operated, the reproduction is stopped (step S18). At this time, if playback processing of still image data is being performed, the playback is stopped with the still image information corresponding to the still image data being output, and if playback processing of video data is being performed, the stop button is operated. Stops when video data is output when the audio data is output, but no audio information is output when audio data is being played back.

 While the reproduction is stopped, it is determined whether or not the stop button has been operated again (step S19). If it is determined that the stop button has been operated again, the process returns to steps S5, S7 and S9 to resume the reproduction process.

 If it is determined that the stop button has not been operated again, it is determined whether or not the storage medium has been ejected from the entrance 21 (step S20). If it is determined that the storage medium has been discharged from the insertion port 21, the process returns to step S1.

 (4) If it is determined that the storage medium has not been discharged from the entrance 21, it is determined whether the power button 11 has been operated and the power has been turned off (step S 21). If it is determined that the power has not been turned off, the process returns to step S18. If it is determined that the power has been turned off, the processing ends.

Although not shown, if it is determined in step S1 that the storage medium has not been inserted into the entrance 21, a step for determining whether the power has been turned off is provided. If it is determined in step S3 that the play button 12 has not been operated, processing is performed to determine whether the storage medium has been ejected from the insertion slot 21 and whether the power has been turned off. I do. In the embodiment shown in FIG. 3, when the reproduction is completed up to the end of the selected data file, the operation returns to the beginning and repeats the reproduction. The operation is performed in the one-file repetition reproduction mode. Terminate the playback process when the playback is completed to the end. It is also possible to configure to operate in the one-file playback mode. In this embodiment, for example, between step S15 and step S17, it is determined whether or not playback has been completed to the end of the selected data file, and it is determined that playback has not been completed to the end. If so, the process proceeds to step S17. If it is determined that the reproduction has been completed to the end, a step for ending the process is provided.

 In addition, the playback process is executed when the playback button 12 is operated after the storage medium is inserted into the insertion slot 21.However, the playback process is executed immediately after the storage medium is inserted into the entrance 21. It can also be done. In this embodiment, step S3 in FIG. 3 is unnecessary.

 In addition, when the stop button 13 is operated to stop the playback process, the playback process is restarted when the stop button 13 is operated again in step S 19, but the playback button 1 2 The playback process may be restarted when the (stop button 13) is operated, and the process may return to step S1 when the stop button 13 (or the playback button 12) is operated. .

 In the above embodiment, the selected one data file is played back, but a plurality of data files can be played back. The operation of the other embodiment of the present invention will be described with reference to the flowchart of FIG. In the present embodiment, it is assumed that a plurality of still image data files, a plurality of moving image data files, and a plurality of audio data files are repeatedly played back. The user can specify an overnight file or an audio data file. For this reason, a multiple file repeat playback mode setting means for setting a multiple still image repeat playback mode, a multiple video repeat playback mode, a multiple audio repeat playback mode, a designated playback mode for designating a file to be played, and a storage medium. A reproduction mode setting means for setting an all file reproduction mode for reproducing all still image data files, all moving image data files, and all audio data files is provided.

After executing the processing of step S2 shown in the flowchart of FIG. It is determined whether or not the image repeat playback mode is set (step Pl). If it is determined that the multiple still image repetitive playback mode is set, it is determined whether or not the designated playback mode is set in the playback mode setting means (step Q1). If it is determined that the designated playback mode is not set, that is, if the all file playback mode for playing all still image data files stored in the storage medium is set, the playback button 12 is operated. (Step Q 2 If it is determined that the reproduction button 12 has not been operated, the process of Step Q 2 is repeated.

 When it is determined that the play button 12 has been operated, it is determined whether or not the data file of the file number n is a still image file (step Q3). If it is determined that the data file with the file number n is still image data, the still image data is reproduced (step Q4). At this time, since audio data may be stored together with the still image data, the audio data is reproduced at the same time.

 It is determined whether or not the stop button 13 has been operated while performing the playback processing of the still image data (step Q5). If it is determined that the stop button 13 has not been operated, it is determined whether or not playback has been completed to the end of the data file (step Q6). Whether or not the reproduction has been completed up to the end of the data file is determined by, for example, whether or not the last end signal of the data file has been detected.

 If it is determined that the reproduction has not been completed to the end of the file, the process returns to step Q4 to continue the reproduction process. If it is determined that the reproduction has been completed to the end of the data file, 1 is added to the file number n (step Q7), and the process returns to step Q3. Here, when the file number n is equal to the number N of data files stored in the storage medium, the value obtained by adding 1 to the file number n is set to 1. If it is determined in step Q3 that the data file having the file number n is not a still image file, the process proceeds to step Q7 to select the next file.

If it is determined in step Q5 that the stop button 13 has been operated, the reproduction process is stopped (step Q8). Then, it is determined whether or not the stop button 13 has been operated again (step Q). If it is determined that the stop button 13 has been operated again, the process returns to step Q4 to resume the reproduction process. If it is determined that the stop button 13 has not been operated again, it is determined whether or not the storage medium has been ejected from the insertion port 21 (step Q10). If it is determined that the storage medium has been ejected from the insertion slot 21, the process returns to step S1 in FIG.

 場合 If it is determined that the storage medium has not been ejected from the entrance 21, it is determined whether the power button 11 has been operated and the power has been turned off (step Q 11). If it is determined that the power is not turned off, return to step Q8. If it is determined that the power has been turned off, the processing ends.

 On the other hand, if it is determined in step Q1 that the designated playback mode has been set, the process waits until a file to be played is designated (step Rl). The file can be specified by, for example, a method of inputting a file number using an input button or the like, or a method of operating a specification button by selecting a file by using a forward button 14 or a return button 15. Then, it is determined whether or not the reproduction button 12 has been operated (step R 2). If it is determined that the play button 12 has not been operated, the process of step R2 is repeated.

 If it is determined that the reproduction button 12 has been operated, it is determined whether or not the data file of the file number n is still image data (step R3). If the data file with file number n is still image data, it is determined whether the data file with file number n is the data file specified in step R1 (step R4). Whether the file with the file number n is the specified data file is determined by, for example, whether or not the file number n matches the specified file number.

 If it is determined that the data file with the file number n is the specified data, the reproduction processing of the still image data is executed (step R5). At this time, since audio data may be stored together with the still image data, the reproduction processing of the audio data is also performed at the same time.

It is determined whether or not the stop button 13 has been operated while performing the playback process of the still image data (step R6). If it is determined that the stop button 13 has not been operated, it is determined whether or not playback has been completed to the end of the data file (step R 7) ₀ If it is determined that the reproduction has not been completed to the end of the data file, the process returns to step R5 to continue the reproduction process. If it is determined that the reproduction has been completed to the end of the data file, 1 is added to the file number n (step R8), and the process returns to step R3. Here, when the file number n is equal to the number N of data files stored in the storage medium, the value obtained by adding 1 to the file number n is set to 1.

 When it is determined in step R3 that the data file with the file number n is not a still image file, and when it is determined in step R4 that the data file with the file number n is not the specified data file. To proceed to step R8, select the next file.

 If it is determined in step P1 that the multiple still image repetitive playback mode is not set, then it is determined whether the multiple video repetitive playback mode is set (step P2). If it is determined that the multiple video repeat playback mode is not set, it is determined whether the multiple audio repeat playback mode is set (step P3). If the multiple sound repetitive playback mode is not set, the process proceeds to step S3 in FIG. 3 to execute the playback process of one file.

 If it is determined in step P2 that the multiple video repeat playback mode is set, or if it is determined in step P3 that the multiple audio repeat playback mode is set, the process is as follows. Except for the data file or the audio data file, the processing is the same as the processing from step Q1 onward, and therefore will not be described.

 Although not shown, if it is determined in step Q2 or step R2 that the play button has not been operated, it is determined whether the storage medium has been ejected from the entrance 21 and whether the power has been turned off. A process is performed to determine whether

In the above, all or specified still image data files or moving image data files are played repeatedly, but all or specified still image data files or moving image data files are played back. It is also possible to configure so that the playback processing is terminated when the playback of the overnight file or the audio file is completed. In this embodiment, for example, between step Q6 and step Q7 and between step R7 and step R8, the file number n is equal to the number N of files stored in the storage medium. File number n is equal to the data file number N. If not, a step for ending the processing is provided.

 In addition, all or specified still image data files, moving image data files, or audio data files are reproduced, but all data files stored in the storage medium are sequentially read and reproduced. You can do it. Further, the same changes as in the embodiment of FIG. 3 are possible.

 Various methods other than JPEG, MPEG, and ADPCM can be used for storing still image data, moving image data, and audio data.

 As described above, the playback device of the present invention is small and lightweight, and is easy to carry. In addition, a single device can reproduce data stored in various storage formats. Further, since it is only necessary to operate the power button, the play button, the stop button, the forward button, the return button, and the like, the data stored in the storage medium can be reproduced by a simple operation. Also, since the configuration is simple, it can be manufactured at low cost. Also, by simply connecting a display device, an audio output device, and a printing device to the output terminal, image information and audio information can be easily confirmed.
