2. Description of the Related Art When a subject is photographed and recorded by a digital still camera or a video camera, a user appropriately adjusts photographing conditions such as white balance, focus, exposure and zoom magnification before recording. However, recording of image information is not always performed under proper shooting conditions, and many failed shooting records occur when shooting conditions are unsuitable.

In the conventional camera device as described above, when an image is reproduced, it is a so-called out-of-focus image because of a failed photographing record, and it is too bright or too dark to see what is in the image. Even an image that cannot be understood is usually played back as it is.

[0004]

However, in many cases, the above-described failure-captured images need not be reproduced by the user, but conventionally, all of those failure-captured images are also reproduced. Since it is like this,
As a result, the user is forced to spend an unnecessary reproduction time (reproduction time of an image captured in failure).

Video cameras that improve this point are also provided. In this improved video camera, when recording an image, the user selects and inputs whether the captured image is “OK” or “NG”, and the corresponding OK / N
The G identification signal is recorded as a digital signal on the tape together with the image data. Then, at the time of edit recording, the control unit of the video camera skips (skips) an unnecessary image portion based on the OK / NG identification signal and reproduces the image to perform edit recording. Is.

According to this video camera, the one designated as "NG" by the user is skipped and is not included in the data after being edited and recorded, so that only the necessary image which the user has designated as "OK" is reproduced. become able to.

However, in the method adopted in this video camera, the user needs to select and input whether the captured image is "OK" or "NG" when recording the image, and the operation is performed. It is troublesome. Further, since the data after the editing and recording does not include the data of the image marked as “NG”, even if there is a case in which the image marked as “NG” is desired to be reproduced later, it can be reproduced. There is a problem that you cannot do it.

In view of the above points, the present invention aims to provide an apparatus and method for skipping images that the user does not want and extracting and reproducing only the image that the user desires. And

Next, the photographing and recording operation and the reproducing operation of the digital camera apparatus as the first embodiment of the image recording / reproducing apparatus configured as described above will be explained. Figure 2
3 is a flow chart for explaining a shooting / recording operation and a reproducing operation of the digital camera device according to the first embodiment. Referring to the flowchart of FIG. 2,
The shooting / recording operation and the reproducing operation will be described.

The operation of the flow chart of FIG. 2 is a processing operation in the control device 10 which is activated when the user performs any input operation through the operation input unit 21. Then, in the reproduction operation, as described above, every time the reproduction button K2 is turned on, one image is displayed on the display unit 6.
This is the case when it is displayed on the screen.

When an input operation is performed by the user, first, in step S1, it is determined whether or not it is a recording instruction operation. In this case, since the recording instruction operation is the operation of the shutter button K1 of the operation input unit 21, it is determined in step S1 whether or not the shutter button is pressed by the photographer.

When it is determined in step S1 that the shutter button has been pressed, the process proceeds to step S2, and the captured image data is compressed and recorded on the disc. further,
In step S3, the camera control data is recorded in association with the recorded image data as the shooting condition data at that time.

That is, in recording a photograph, the photographer presses the shutter button K1 of the operation input unit 21 while confirming the image displayed on the display screen of the display unit 6, so that the control device 10 causes that. The shutter mechanism of the camera block 1 is driven at a preset shutter speed according to the operation input of the shutter button K1.

Then, the CC of the camera block 1 at that time
The image pickup signal from D is supplied to the image pickup signal processing circuit 3,
The image data in the component format for recording is sent to the control device 10, so that the control device 10 compresses the image data in the image signal compression encoding / decoding unit 24.
Supply to. Image signal compression encoding / decoding unit 24
Returns the compression-encoded image data to the control device 10. The control device 10 supplies this compression-encoded image data to the disc drive 22 to drive the disc 2
Control to write in 3. The above is the processing operation from step S1 to step S2.

Next, the control device 10 supplies the camera control data at that time to the camera control data recording encoding / decoding section 25. The camera control data recording encoding / decoding unit 25 performs recording encoding processing on the received camera control data and returns it to the control device 10. The control device 10 supplies the received record-encoded camera control data to the disc drive 22 and associates it with the image data recorded immediately before and stores it in the disc medium 23.
Control to write to. The above is the processing operation of step S3. This completes the shooting / recording operation in the first embodiment.

Next, when it is determined in step S1 that the input operation is not the recording instruction, the process proceeds to step S4, and it is determined whether or not the input operation is the reproduction instruction operation.
If it is determined that it is not the reproduction instruction operation, step S
Then, the process proceeds to step 5 to perform a process according to the instruction operation.

If it is determined in step S4 that the reproduction instruction operation has been performed, the flow advances to step S6 to check the state of the reproduction mode changeover switch K3 to determine whether the reproduction mode is the skip reproduction mode. When it is determined in step S6 that the normal reproduction mode is selected instead of the skip reproduction mode, step S11
Then, the image data to be reproduced recorded on the disk medium 23 is read out, decoded by the image data compression encoding / decoding unit 24 and decompressed, and the reproduced image is displayed on the screen of the display unit 6 for normal reproduction. Do.

On the other hand, if it is decided at step S6 that the reproduction mode is the skip reproduction mode, then the processing advances to step S7, at which the camera control data, which is the information of the photographing conditions for the image data to be reproduced, is stored in the disk medium 23. And is decoded by the camera control data recording encoding / decoding unit 25.

Then, in step S8, it is determined whether the focus data of the decoded camera control data is within the proper range. When it is determined to be appropriate,
In step S9, it is determined whether or not the exposure condition is within the proper range, based on the exposure data in the decoded camera control data. When it is determined that the exposure is within the proper range, the process proceeds to step S10, and it is determined whether or not the white balance is proper from the white balance adjustment data in the decoded camera control data.

When it is determined in step S10 that the white balance is appropriate, that is, when the image capturing conditions are appropriate and the image capturing is not a failure image capturing, the process proceeds to step S11 and is recorded on the disk medium 23. The image data to be reproduced is read out, decoded by the image data compression encoding / decoding unit 24 and decompressed, and the reproduced image is displayed on the screen of the display unit 6 for normal reproduction.

On the other hand, when it is determined in step S8 that the focus data is not in the proper range, or in step S8.
When it is determined in step 9 that the exposure is not within the proper range, or when it is determined in step S10 that the white balance is not appropriate, the process proceeds to step S12, and the image that was the reproduction target is skipped without being reproduced. In the next step S13, the camera control data for the next image data is read from the disk medium 23.

After step S13, the process returns to step S8, and the processes after step S8 are repeated.
That is, the camera control data (shooting condition data) for the next image read in step S13 is analyzed in the same manner as described above to check whether the shooting is unsuccessful. S1
In 1, the normal reproduction is performed as described above. If it is determined that the shooting has failed, in step S12,
Further, the image is skipped, and further, step S13
Then, the camera control data for the next image is read out, and then the process returns to step S8 to repeat the above-described processing operation in the same manner.

As described above, in the first embodiment, when the still image is photographed and recorded, the camera control data together with the image data is used as the information of the photographing condition in the photographing. The data is recorded in the disc recording medium 23 in association with the data, and at the time of reproduction, the information on the photographing condition recorded in the disc medium 23 is analyzed to determine whether or not the still image is an image of failure photographing.

That is, if the recorded image is out of focus, too bright, or too dark,
It is determined whether or not it is a shooting failure scene in which it is not possible to know what is in the image. If it is not a failure shooting, the still image is played back as usual, and if it is a failure shooting, the still image is skipped without being played back and the next recorded image portion is played back. To Therefore, it is possible to automatically extract only good-looking images that are not unsuccessful shots and quickly reproduce them.

Note that the above is the case of shooting and recording still images, but in this embodiment, since the disk medium 23 has a relatively large capacity, not only still images (still images) but also several seconds to several minutes. It is also possible to record and record the moving image.

For example, pressing and holding the shutter button,
Further, by providing a recording mode selection button, setting the moving image recording mode with the recording mode selection button, and setting the shutter button as a recording start button, it is possible to shoot and record a moving image of several seconds to several minutes. . However, the image data of a moving image is compressed and recorded. As a compression method in that case, for example, MP
EG (Moving Picture Experts)
Group) method can be used.

In that case, similar to the above, the camera control data is also recorded, but the camera control data is changed not only at the start of recording the moving image but also during the recording of the moving image for several seconds to several minutes. If so, the changed camera control data is also recorded.

In the case where the still image and the moving image can be recorded together, when the reproduction button K3 is pressed, if the next image is the moving image, that moving image portion is reproduced. In addition, when the playback mode is skip playback mode, the camera control data is read in parallel with the reading of the moving image data or prior to the reading of the moving image data. In the same manner as described above, it is analyzed and determined whether or not the proper shooting conditions are satisfied, and a scene with poor image quality is skipped and reproduced.

[Second Embodiment] In the second embodiment, the image is out of focus, too bright or too dark, and it is difficult to know what is in the image. The determination as to whether or not the scene has failed is made by analyzing the image data read from the disk medium 23. Therefore, as in the first embodiment,
At the time of recording, it is not necessary to record the camera control data on the disk medium 23 together with the image data. Other configurations are similar to those of the above-described first embodiment.

FIG. 3 is a block diagram showing a configuration example of a digital camera device in the case of the second embodiment. As can be seen from a comparison between FIG. 3 and FIG. 1, in the second embodiment, instead of the camera control data recording / encoding / decoding unit 25, the image data read from the disk medium 23 is attached to the image data. An image feature analysis unit 26 is provided which extracts and analyzes the features and supplies the analysis result to the control device 10. Other configurations are shown in FIG.
The configuration is exactly the same as that of the first embodiment shown in FIG.

In the second embodiment, the image feature analysis unit 26 performs feature extraction on the image data read from the disk medium 23 and analyzes the extracted features. In this case, the characteristic items to be extracted are the frequency distribution for the focus and the signal level distribution for the image that is too bright or too dark.

The control device 10 determines whether or not to skip an image based on the analysis result from the image feature analysis unit 26 in the skip reproduction mode during reproduction.

Next, the photographing / recording operation and the reproducing operation of the digital camera device as the second embodiment configured as described above will be explained. FIG. 4 is a flow chart for explaining the shooting / recording operation and the reproducing operation of the digital camera device according to the second embodiment. This Figure 4
The shooting / recording operation and the reproducing operation will be described with reference to the flowchart of FIG.

As in the case of FIG. 2 described above, the operation of the flowchart of FIG.
This is a processing operation in the control device 10 that is activated when any input operation is performed through. And the playback operation is
As described above, 1 is set every time the play button K2 is turned on.
This is a case where a single image is displayed on the screen of the display unit 6.

When an input operation is performed by the user, first, in step S21, it is determined whether or not it is a recording instruction operation. In this case, since the recording instruction operation is the operation of the shutter button K1 of the operation input unit 21, in this step S21, it is determined whether or not the shutter button is pressed by the photographer.

If it is decided at step S21 that the shutter button is pressed, then the processing advances to step S22, at which the photographed image data is compressed and recorded on the disc. That is, in recording a photograph, the photographer presses the shutter button K1 of the operation input unit 21 while checking the image displayed on the display screen of the display unit 6, so that the control device 1
0 corresponds to the operation input of the shutter button K1
The shutter mechanism of the camera block 1 is driven at a preset shutter speed.

Then, the CC of the camera block 1 at that time
The image pickup signal from D is supplied to the image pickup signal processing circuit 3,
The image data in the component format for recording is sent to the control device 10, so that the control device 10 compresses the image data in the image signal compression encoding / decoding unit 24.
Supply to. Image signal compression encoding / decoding unit 24
Returns the compression-encoded image data to the control device 10. The control device 10 supplies this compression-encoded image data to the disc drive 22 to drive the disc 2
Control to write in 3. The above is step S21.
It is the processing operation from to S22. Thus, the shooting / recording operation in the second embodiment is completed.

Next, when it is determined in step S21 that the input operation is not the recording instruction, step S23.
Then, it is determined whether or not the input operation is a reproduction instructing operation. When it is determined that the input operation is not a reproduction instructing operation, the process proceeds to step S24, and processing according to the instructed operation is performed.

If it is determined in step S23 that the reproduction instruction operation has been performed, the flow advances to step S25 to check the state of the reproduction mode changeover switch K3 to determine whether or not the reproduction mode is the skip reproduction mode. If it is determined in step S25 that the normal reproduction mode is selected instead of the skip reproduction mode, step S25
In step 30, the image data to be reproduced recorded on the disk medium 23 is read out, decoded by the image data compression encoding / decoding unit 24 to decompress, and the reproduced image is displayed on the screen of the display unit 6 to display the normal image. Play back.

On the other hand, if it is decided at step S25 that the reproduction mode is the skip reproduction mode, then the processing advances to step S26, at which the image data to be reproduced is
It is read from the disk medium 23 and passed to the image feature analysis unit 26. The image feature analysis unit 26 extracts and analyzes the above-mentioned feature items from the received image data, and returns the analysis result to the control device 10.

Based on the received analysis result, the control device 10 determines whether or not the image has a good image quality, and when it determines that the image quality is poor, the image is skipped. That is, first, in step S27, it is determined whether there are many low-frequency components by referring to the frequency distribution of the received analysis result. The fact that there are many low-frequency components means that the image is out of focus.

The threshold value of the ratio regarding whether or not the low frequency component is large in step S27 may be a predetermined fixed value or may be selected by the user. good.

If it is determined in step S27 that there are many low-frequency components, the process proceeds to step S31, the image to be reproduced is skipped without being reproduced, and in the next step S32, the next image data is transferred to the disk medium 23. Read out and return to step S27.

When it is determined in step S27 that the low frequency component is not large and the image is not out of focus, the process proceeds to step S28, the signal level distribution in the analysis data received from the image feature analysis unit 26 is referred to, and the signal level distribution is referred to. Determines whether 90% or more of bright parts are too bright to understand what is in the image.

The threshold value for the proportion occupied by the bright portion of 90% or more in step S28 may be a predetermined fixed value, or may be a fixed value.
The user may select it.

When it is determined in this step S28 that the signal level distribution has many bright portions of 90% or more, the process proceeds to step S31, the image to be reproduced is skipped without being reproduced, and the next image is reproduced. Step S32
At, the next image data is read from the disk medium 23, and the process returns to step S27.

When it is determined in step S28 that the signal level distribution does not include many bright portions of 90% or more, the process proceeds to step S29, where the signal level distribution is 1
It is determined whether or not the dark portion of 0% or less is so large that the image is too dark and the user cannot know what is in the image. The threshold value for the proportion occupied by the dark portion of 10% or less in step S29 may be a predetermined fixed value, or may be selectable by the user.

When it is determined in step S29 that the signal level distribution has many dark portions of 10% or less, the process proceeds to step S31, and the image to be reproduced is skipped without being reproduced, and the next image is reproduced. In step S32, the next image data is read from the disk medium 23, and the process returns to step S27.

Then, when it is determined in step S29 that there are not many dark areas where the signal level distribution is 10% or less, that is, it is not out of focus, and it is neither too bright nor too dark. In some cases, the process proceeds to step S30, and the image data read from the disk medium 23 is image data compressed / encoded.
Decoding is performed by the decoding unit 24 to decompress the compressed image, a reproduced image is displayed on the screen of the display unit 6, and normal reproduction is performed.

As described above, according to the second embodiment, at the time of reproduction, the image data recorded on the disk medium 23 is subjected to a characteristic analysis, and the still image is detected as a failed image on the basis of the analysis result. Determine if it is an image. That is, it is determined whether the recorded image is out of focus, is too bright, or is too dark, and the shooting failure scene is such that it is not possible to know what is in the image.

Then, when it is determined that the shooting is not a failure shooting, the still image is reproduced normally, and when it is determined that the shooting is a failure shooting, the still image is skipped without being played and the next image is skipped. The recorded image portion is reproduced. Therefore, it is possible to automatically extract only good-looking images that are not unsuccessful shots and quickly reproduce them.

Although the above is the case of shooting and recording still images, this second embodiment also shows still images (still images).
It can be applied not only to playback of captured and recorded moving images.

In this case, the image data is read from the disk medium 23 at a high speed, stored in the buffer memory, and the display image data is sequentially output from the buffer memory to the display controller 4 and the display memory 5.
By supplying the image data to the display unit 6 via the, a margin time is provided for reading the image data from the disk medium 23.
Then, the skip reproduction can be realized by pre-reading the image data of the moving image in the margin time and performing the above-described analysis and determination.

It should be noted that in relation to the moving image data, the first
Similar to the embodiment of the present invention, the camera control data is recorded as the shooting condition, and the image analysis as described above is performed only on the image portion where the camera control data largely changes in the skip playback mode in the case of playing back this moving image. You may decide to skip and skip an image. In an image group in which camera control data such as zoom information and focus information has not changed significantly, if you analyze a part of the image such as the beginning, you can use the analysis result as it is as the analysis information of the group of images. This is because it is considered safe.

[Third Embodiment] The third embodiment is a development of the present invention. In the third embodiment, rather than skipping and playing back the failed shooting portion,
Only the image including the image portion of interest to the user is automatically extracted, and the other images can be skipped and reproduced.

For example, the third embodiment will be described by taking as an example the case where only an image showing a specific person is automatically extracted and reproduced.

In the third embodiment, prior to reproduction, the user designates an image portion that he or she is interested in. For example, in an image including a plurality of persons as shown in FIG. 5 (A), when an image including a leftmost person is to be extracted and reproduced, the user does as shown in FIG. 5 (B). Then, the area of the image portion of interest is designated with reference to the cursor CS on the screen through the operation input unit 21. At this time, as shown in FIG. 5B, the area of the image portion of interest designated by the user is shown on the screen as an area AR surrounded by a dotted line so that the user can confirm it. .

In this way, the information of the designated image portion is stored in the predetermined memory in advance. Then, in the third embodiment, when the skip reproduction is instructed, only the image including the designated image portion is reproduced.

FIG. 6 is a block diagram showing a configuration example of a digital camera device in the case of the third embodiment. As can be seen from the comparison with FIG. 1, the camera control data recording encoder / decoder 25 is not provided in the third embodiment, and the area designated with reference to the cursor CS is set as described above. A designated image partial memory 27 for storing data of the image part of the AR, and the disk medium 2
An image comparison / analysis unit 28 is provided for performing comparison analysis of the image data read from the image data No. 3 with the image portion written in the designated image portion memory 27 and supplying the analysis result to the control device 10. Other configurations are shown in FIG.
The configuration is exactly the same as that of the first embodiment shown in FIG.

In the third embodiment, the control device 10
Cooperates with the image comparison / analysis unit 28 to detect an image having an image portion similar to the image portion stored in the designated image portion memory 27, and reproduce only the detected image. When the designated image portion is a person as shown in FIG. 5, the photographing / recording operation and the reproducing operation of the digital camera device according to the third embodiment will be described with reference to the flowchart of FIG. 7.

Similar to the case of FIG. 2 described above, the operation of the flowchart of FIG.
This is a processing operation in the control device 10 that is activated when any input operation is performed through. And the playback operation is
Similar to the above, one image is displayed on the screen of the display unit 6 every time the reproduction button K2 is turned on.

When an input operation is performed by the user, first, in step S41, it is determined whether or not it is a recording instruction operation. In this case, since the recording instruction operation is the operation of the shutter button K1 of the operation input unit 21, in this step S41, it is determined whether or not the shutter button is pressed by the photographer.

If it is decided at step S41 that the shutter button is pressed, then the processing advances to step S42, at which the photographed image data is compressed and recorded on the disc. That is, in recording a photograph, the photographer presses the shutter button K1 of the operation input unit 21 while checking the image displayed on the display screen of the display unit 6, so that the control device 1
0 corresponds to the operation input of the shutter button K1
The shutter mechanism of the camera block 1 is driven at a preset shutter speed.

Then, at that time, CC of the camera block 1
The image pickup signal from D is supplied to the image pickup signal processing circuit 3,
The image data in the component format for recording is sent to the control device 10, so that the control device 10 compresses the image data in the image signal compression encoding / decoding unit 24.
Supply to. Image signal compression encoding / decoding unit 24
Returns the compression-encoded image data to the control device 10. The control device 10 supplies this compression-encoded image data to the disc drive 22 to drive the disc 2
Control to write in 3. The above is step S41.
It is the processing operation from to S42. This completes the shooting and recording operation in the third embodiment.

Next, when it is determined in step S41 that the input operation is not the recording instruction, step S43.
Then, it is determined whether or not the input operation is a reproduction instructing operation. When it is determined that the input operation is not a reproduction instructing operation, the process proceeds to step S44, and processing according to the instructed operation is performed.

If it is determined in step S43 that the reproduction instruction operation has been performed, the flow advances to step S45 to check the state of the reproduction mode changeover switch K3 to determine whether the reproduction mode is the skip reproduction mode. When it is determined in step S45 that the normal reproduction mode is selected instead of the skip reproduction mode, step S45
Proceeding to 51, the image data to be reproduced recorded on the disk medium 23 is read out, decoded by the image data compression encoding / decoding unit 24 to decompress the compressed image, and the reproduced image is displayed on the screen of the display unit 6 to display the normal Play back.

On the other hand, if it is decided at step S45 that the reproduction mode is the skip reproduction mode, then the processing advances to step S46, at which the image data to be reproduced is
It is read from the disk medium 23 and passed to the image comparison / analysis unit 28. Then, in step S47, the image data of the designated image portion stored in the designated image portion memory 27 is also passed to the image comparison / analysis unit 28 to instruct comparison and comparison.

The image comparison / analysis unit 28 analyzes whether or not the received image data includes an image portion similar to the designated image portion, and returns the analysis result to the control device 10. Based on the received analysis result, the control device 10
It is determined whether or not the image to be reproduced is an image including an image portion similar to the designated image portion, and normal reproduction or skip is performed according to the determination result.

That is, first, in step S48, it is determined whether or not there is an image portion similar to the skin color distribution of the person in the designated image portion in the image to be reproduced. If it is determined that there is no such image portion, step S52.
In step S53, the next image data is read out from the disk medium 23, and the process returns to step S47.

When it is determined in step S48 that there is an image portion having a similar skin color distribution, step S4
In step 9, it is determined whether the image to be reproduced has an image portion similar to the hairstyle of the person in the designated image portion.
When it is determined that there is no such image portion, the process proceeds to step S52, the image that was the reproduction target is skipped without being reproduced, and in the next step S53, the next image data is read from the disk medium 23, and the step S47
Return to.

When it is determined in this step S49 that there is an image portion having a similar hairstyle, the process proceeds to step S50, and the image to be reproduced has an image portion similar to the figure of the person in the designated image portion. Determine whether or not. If it is determined that there is no such image portion, the process proceeds to step S52, the image that is the reproduction target is skipped without being reproduced, and in the next step S53,
The next image data is read from the disk medium 23, and the process returns to step S47.

When it is determined in step S50 that there is an image portion having a similar body type, the process proceeds to step S51, and the image data read from the disk medium 23 is
The image data compression encoding / decoding unit 24 decodes and decompresses the compressed data, displays a reproduced image on the screen of the display unit 6, and performs normal reproduction.

As described above, in the third embodiment, at the time of reproduction, the image portion of interest to the user is designated from the image based on the image data recorded on the disk medium 23, and the designated image portion is designated. Only the provided images can be automatically extracted and reproduced, which is very convenient.

The example of FIG. 7 is an example of a method of searching for a similar image part when a person is assumed as the specified image part. As a method of searching for an image part similar to the specified image part, the search image is used. It goes without saying that it is determined according to the object and is not limited to the example of FIG. 7. For example, when searching for an image including a building such as a specific building, the color, shape, or pattern of the building can be used for the search.

Although the above is the case of shooting and recording still images, the third embodiment is not limited to still images (still images) as in the second embodiment described above.
It can also be applied to the reproduction of a moving image recorded and recorded.

[Fourth Embodiment] In the above embodiments, the case where only the image data is recorded and reproduced has been described, but the data of the captured image and the audio information at the time of the recording are recorded in the recording medium. In some cases. In that case, for example, specify a specific audio information part, and during playback,
By searching for a voice portion similar to the designated voice information portion, it is possible to extract and reproduce only the image including the image portion corresponding to the designated voice information portion.

For example, in the above-described third embodiment, instead of designating the person image portion with the cursor, the speech portion spoken by the person is designated as the voice of interest. Then, the voice portion is stored in the memory. At the time of reproduction, in the skip reproduction mode, the audio part stored in the memory is compared with the audio read from the disk medium to search for an approximate audio part. Then, when a similar voice portion is searched, only the image corresponding to the voice portion is reproduced.

As a result, as in the case of the third embodiment, it is possible to reproduce the image of interest to the user by extracting the audio information as a clue.

[Other Modifications] Although the above embodiment has been described as a case of a digital still camera,
Of course, the present invention can be applied to a video camera capable of recording not only moving images but also still images.

Further, the method of the present invention is not limited to the camera device as described above, but can be applied to the case of reproducing the image from the recording medium on which the image information is recorded.

Moreover, the recording medium is not limited to the above-mentioned disk medium. However, when a disk medium is used, the effect of the present invention is effectively exhibited due to the ease of access.
