Description

The present invention relates to an information processing apparatus .

  Conventionally, large-capacity memory cards, optical disks, and the like using a semiconductor flash memory or a magneto-optical medium as a recording medium are known. These recording media, unlike magnetic tapes and magnetic disks, do not cause physical destruction when the detection head and the medium are not in contact with each other, so that reproduced data is not deteriorated even if it is repeatedly reproduced. Therefore, it is used for many purposes for recording and reproducing image data and audio data. In particular, in the field of digital cameras, almost all models announced by various companies employ memory cards using flash memory as their recording media. This flash memory card is becoming smaller and larger capacity year by year, and the price is drastically decreasing. The unit price per bit is approaching that of magnetic media such as magnetic tape and hard disk.

  On the other hand, a digital camera using a small MO disk as a recording medium has been announced, and the bit unit price is even lower than that of the flash memory described above. In recent years, a small memory card in which semiconductor memory cells are stacked in a three-dimensional structure has been announced. In this card, the number of times of writing is limited to one time, but it is said that the recording density will be increased and the price will be equivalent to that of film in the future. In this way, the price can be reduced if the guaranteed number of rewrites is reduced to a certain small value, even if it is not possible to record only once. If such a medium is used, it is possible to supply a memory card or a camera that can be used by the user in a disposable manner.

  The above-mentioned flash memory has a considerably large number of endurances for rewriting due to the progress of semiconductor technology, and can be used by the user as having almost endless endurance. . The above-mentioned MO disk has a very small number of endurances compared to this, and the endurance number is said to be about 300 in the CD-RW used in the above-mentioned camera.

In this way, since the maximum number of rewrites differs depending on the storage medium, the user may select a different storage medium according to the purpose of use.

However, as the number of storage media used by users increases, there is a problem that it is difficult to reliably grasp the usage status of each storage medium.

  As a method for solving such a problem, Japanese Patent Application Laid-Open No. 6-223240 discloses an invention in which a memory card itself has a function of managing the number of rewrites. In this case, the memory card is provided with a counter and a warning signal generating means, and the remaining number of times that can be rewritten by the light emitting element provided on the memory card when the camera is mounted is roughly displayed. However, as described above, since this method is provided with warning display means, counting means, etc. in the card, the structure becomes complicated and as a result, the price is not low. Further, since the card is usually stored in the camera, it is difficult to confirm the warning signal when the camera is mounted.

  Japanese Patent Laid-Open No. 5-73433 discloses that the number of times of rewriting is stored for each block, and rewriting is prohibited for a block that has reached a predetermined number of times and averaged over rewriting. That is, the idea is to increase the number of rewrites in recording a normal data file by using a plurality of blocks on average.

  Japanese Laid-Open Patent Publication No. 11-250675 discloses that the rewriting life is determined based on the phenomenon that the erase time of the flash memory increases as the endurance of rewriting approaches, and a warning is issued when it is determined that the rewriting life has been reached. Has been. However, with this method, it is impossible to determine the lifetime unless it is recorded once. Further, similar to the above-mentioned disclosure, it is a disclosure about processing at the time of recording a normal data file, and a display or warning related to the formatting operation. It is not a disclosure.

An object of the present invention, Ru der to provide an information processing apparatus which the user can reliably grasp the usage status of the storage medium.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a digital camera according to an embodiment of the present invention, FIG. 2 is a block diagram mainly showing signal flow inside the camera of operations and functional blocks shown in FIG. 1, and FIG. Shows the internal configuration block of a memory card composed of a finite storage medium. The operation procedure when this card is mounted on the digital camera shown in FIGS. 1 and 2 is shown in the flowcharts of FIGS. However, functions and operation members that are not related to the present invention are omitted in any of the drawings.

  First, in FIG. 1, when the user inserts the memory card shown in FIG. 3 into the card slot 101, the memory card type information and captured image information are displayed on the LCD monitor 102. The user reproduces an image with the selection button 103, and after selecting an image to be deleted, presses the delete button 104 to delete the image. This operation can be performed any number of times. On the other hand, all images recorded on the memory card can be erased at once by pressing the format button 105. At the time of these erasures, a predetermined warning is displayed on the monitor 102. Further, a buzzer 106 is also used as a warning by voice to prevent erroneous erasure by the user.

  When the preparation for shooting is completed in this way, the process moves to the actual shooting operation of the subject. When the shutter button 107 is pressed, the subject is imaged on the CCD (not shown) in the camera through the shooting lens 108, and predetermined signal processing is performed. The applied shooting data is recorded on the memory card. Although not described here, the digital camera can of course record not only still images but also moving images and audio data. Further, the above-described deletion or formatting of the image and sound data recorded on the memory card may be performed at any time before and after the photographing. FIG. 2 shows the flow of signals between the above-described display and operation units in the camera. Here, in FIG. 2, the same functional units as those in FIG. 1 use the same numbers.

  First, when a power switch (not shown) is turned on and power is supplied to the camera, the CPU 201 reads card information and image data from a memory card installed in the card slot 101. Here, the memory card may be attached to the camera either before or after the power switch is turned on. The read image data is displayed on the LCD monitor 102 after being subjected to predetermined reproduction signal processing. Here, the card information is, for example, the maximum rewritable number information of the memory card. Based on this information, the CPU performs a predetermined display on the LCD monitor 102 or the buzzer 106 has attached a finite rewritable medium. To the user. Further, the CPU 201 controls writing and erasing of images on the memory card based on the card information. Based on the signal from the selection button 103, the CPU 201 reads the selection screen from the memory card and displays it on the monitor 102.

  When the delete button 104 is pressed, the CPU 201 receiving the information creates new FAT information by deleting only the arrangement information of the image data currently selected and displayed from the FAT area in the memory card, and stores it in the memory card. Write. At this time, the image data itself is not deleted. On the other hand, when the format button 105 is pressed, the CPU 201 erases all the data in the memory card including the image data itself recorded on the memory card and the above-described FAT information. When the shutter button 107 is pressed for shooting, the CPU 201 performs predetermined recording signal processing on the shooting data and then records it on the memory card.

  Next, the internal configuration of the memory card will be described with reference to FIG. In FIG. 3, digital data of images and sounds sent through the card slot of the digital camera is sequentially recorded in the data file recording area 302 through the writing / reading control unit 301. An information recording area 303 surrounded by a large wavy line is an area in which arrangement information of a plurality of images and audio digital data recorded in the data file recording area 302, the number of rewrites of the arrangement information, and the like are recorded. The information recording area 303 is further divided into a plurality of small blocks described below. The first information recording area 304 is an area for recording the number of times that the memory card has been formatted. When the memory card is formatted, all data in the data file recording area 302 is erased.

  When the memory card is attached to the digital camera, the CPU 201 first checks the presence or absence of the first information recording area and the second information recording area described later. If the presence of these areas is confirmed, the memory card is read based on the contents read from the area. Is displayed on the LCD monitor 102 or warned by voice. If the format button 105 is pressed after that, the CPU 201 deletes all data in the memory card, and then creates new number data by adding 1 to the above-mentioned read format number so far. Data is written to the first information recording area 304 via the read / write controller 301. In the second information recording area 305, information indicating the type of the storage medium in the data file recording area 305, the maximum number of rewritable times of the storage medium, and the like are recorded. The CPU 201 compares and displays a warning or a warning that no more formatting is possible if they match.

  Note that the second information area 305 can be omitted if the remaining number of times that can be formatted is recorded in the first information area 304 instead of the number of times of formatting described above. However, in that case, since the total number of formats that can be formatted is not known, it is difficult to display the number of times on the LCD monitor 102 as a bar. If the second information recording area contains information indicating the type of storage medium instead of the maximum number of rewrites, for example, information indicating CD-RW, the CPU 201 sets the maximum number of rewrites on the camera side as, for example, 300. Set the number of times.

In the third information recording area 306, the number of rewrites of the fourth information area 307 is recorded. In the fourth information recording area 307, FAT information indicating the arrangement information when the above-described image and audio data is recorded in the data file recording area 302 is recorded. This FAT information is updated each time image or audio file data is newly added to the memory card, and is frequently updated. Therefore, the number of rewrites is also frequently updated, so that the third information recording area 306 is rewritten. The number of times reaches the rewrite limit number earlier than other areas. The fourth information recording area 307 also reaches the FAT rewrite limit number at the same time. Upon detecting this, the CPU 201 initializes the number of times of writing to 1, and newly creates new FAT information in the fifth information recording area 308 and the sixth information recording area 309 indicated by fine wavy lines in FIG. Each is recorded, and in the future, the same writing process as in the third information recording area 306 and the fourth information recording area 307 described so far will be performed on this area. When the number of times of the fifth record information area 308 also reaches the maximum number of rewrites, new seventh information record areas and eighth information record areas (not shown) are created again as before. As in the case of the previous number of formatting, the remaining number of rewrites may be written in the fifth information recording area instead of the number of rewritten times in the fifth information area.

  The FAT information is updated not only when an image or audio data is written but also when an image or audio data selected by the selection button 103 described above is deleted by a deletion button 104. In other words, when this deletion operation is performed, new FAT information is created in which the data relating to the recording location of the selected image data is deleted from the existing FAT information. For this reason, once deleted image and audio information cannot normally be reproduced. However, since the image and audio data itself remains in the data file recording area 302 as described above, it is not impossible to reproduce this data unless new data is written on the data. On the other hand, in the case of the format described above, the entire data recording area 302 is erased, so that it is impossible to reproduce all the image and sound data recorded so far. In this format, there are a method of erasing all data in the data file recording area 302 and the information recording area 303, and a method of erasing only the data file recording area and not erasing the information recording area. May be adopted.

  The creation of FAT information in the information recording area 303 and the update of the number of rewrites described so far may be performed by the read / write control unit 301 in the memory card or the CPU 201 of the digital camera. Also good.

  In addition, since the information recording area 303 described so far only records the number of times information, the address of the image and audio data array, etc., even if the individual information recording areas 306, 307, 308, 309,. And so on, the capacity required for that is much smaller than the data file recording area 302 for storing image and audio data, and is almost infinite in the memory card. It can be considered that there is a small area for each individual information record.

  Next, the operation of the camera will be described in detail based on the flowchart of FIG. When the camera is turned on in step S401, the camera determines in step S402 whether a memory card is attached to the camera. If it is confirmed that the memory card is attached, the camera checks in step S403 whether the first information recording area 304 and the second information recording area 305 described above exist in the memory card that has been installed. . If these information recording areas are not confirmed, in step S404, the CPU 201 determines that a memory card made of a normal medium with no limit on the number of rewrites is loaded, and performs processing such as shooting / recording / playback / erasing. I do. If the power is not turned off in step S405, it is confirmed in step S406 whether the memory card has been pulled out. If the memory card has not been pulled out, the process returns to step S404 to continue normal memory card processing. If the memory card has been pulled out, the process returns to step S402 to wait for the installation of the memory card, and the power is turned off in step S405. This operation is continued until confirmation.

  On the other hand, if it is confirmed that the memory card inserted in step S403 is a finite rewrite card, the information written in the first, second, third and fourth information recording areas is read in step S407. Here, in step S409 in FIG. 4, the third information recording area is represented as the Kth area, and the fourth information recording area is represented as the (K + 1) th area. As described above, the third information recording area 306, the fourth information recording area, and the like. 307 is frequently rewritten, and as a result, these areas are successively new areas such as a fifth information recording area 308, a sixth information recording area 309, and a seventh information recording area and an eighth information recording area (not shown). Therefore, the area in which the latest FAT information rewrite count is recorded is represented as the Kth area, and the latest FAT information recording area is represented as the (K + 1) th area.

  In step S408, the maximum number of rewrites is set in the CPU 201 based on the card type information or the maximum number of rewrites written in the second information area. Here, it may be set to a value smaller than the number of times of reading from the card with a margin. In step S409, based on the information written in the first and second information recording areas, the LCD monitor 102 displays that the memory card currently installed is a finite rewritable card and the remaining number of rewritable times. An example of this display screen is shown in FIGS. FIG. 8A shows that the card is a finite rewritable card, FIG. 8B shows an example in which the remaining number of formats that can be formatted is displayed as a numerical value, and FIG. 8C shows an example in which the approximate number of remaining formats that can be formatted is displayed as a bar. Is shown. The display in FIG. 8A may be omitted if the display in FIG. 8B or FIG. 8C is present. Furthermore, if the buzzer 106 is sounded for a short period of time in addition to these displays, it is effective because the user can be further cautioned when using the memory card.

In step S410, the number of formatted times recorded in the first information recording area 304 is confirmed. If the predetermined number of rewrites set in the CPU 201 has not yet been reached, the process proceeds to step S411. If it is determined in step S409 that the predetermined number of rewrites has been reached, the process proceeds to step S413 in FIG. In step S411, it is confirmed whether there is a format instruction. If the format button 105 is pressed, the CPU 201 performs format processing corresponding to the finite write medium card as described above in step S412. Details of this formatting process are shown in FIG. In FIG. 6, the CPU 201 erases all the data written in the data file recording area 302 in step S411, and adds 1 to the number of formats written in the first information recording area 304 in the next step S4122. When a numerical value is written in the first information recording area 304 and the formatting process is completed, the process returns to step S410 in FIG. If there is no format instruction in step S411, the process proceeds to step S414 in FIG.

  Next, description will be made based on FIG. If the number of rewrites reaches the predetermined number in step S410 of FIG. 4 described above, a display indicating that the memory card cannot be formatted any more is displayed in step S413. FIG. 8D shows an example of the LCD display in this case. Also in this case, as in the case of step S409, if the buzzer 106 is sounded for a short period in addition to the monitor display, the user can be alerted when using the memory card, which is effective. Furthermore, a configuration may be adopted in which the operation itself is not accepted so that a format instruction cannot be issued by pressing the format button 105. Alternatively, if the camera is configured such that various operations can be selected in a menu format on the LCD monitor, the format instruction display itself may be eliminated.

  In step S414, the presence / absence of a deletion instruction from the user is detected. If there is no deletion instruction in this step S414, the operation and display related to the data erasure are completed here, and the subject photographing sequence from step S415 is entered. If the release button 107 is pressed in step S415, a normal photographing operation is performed in step S416, and the image data photographed in step S417 is written in the data file recording area 302 and information related to FAT shown in step S418 is also rewritten. . The process in step S418 is performed in the same manner when a deletion instruction is issued in step S414 described above.

The process of step S418 will be described with reference to FIG. It is checked in step S4181 if the number of times of the third information recording area 306 read in step S407 of FIG. 4 has reached the predetermined number of rewrites. Again, as described above, the latest information recording area is described as the Kth area. When newly recording image data and erasing the selected image, the newly created FAT information and the number of FAT information rewrites are the same information recording area as before, for example, the FAT information is rewritten in the area 307. It is confirmed whether or not it can be written in the area 306. If the number of rewrites in these areas has reached the predetermined number, the process proceeds to step S4182, where the number of rewrites is set to an initial value, for example, 1, and this value is written in the new fifth information recording area 308, and in step S4183. New FAT information is written in the sixth information recording area 309. Then step S4184
The fifth information recording area is set as the latest information area.

  On the other hand, if it is confirmed in step S4181 that the number of rewrites has not reached the predetermined number, the process proceeds to step S4185, and a value obtained by increasing the number of rewrites by 1 in the same third information recording area 306 as before is obtained in step S4186. 4 In the information recording area 307, new FAT information is recorded. Up to this point, step S418, which is a process for new image recording and image deletion, is completed, and it is confirmed in step S419 in FIG. Even if the release is not performed in step S415, the process proceeds to step S419. In this step S419, as long as the power of the camera is not turned off, the process returns to step S411 in FIG. 4 and repeats a loop waiting for a format instruction in step S411, a deletion instruction in step S414, and a release instruction in step S415.

Next, the predetermined number of rewrites set by the CPU 201 described so far will be described. For example, there is almost no need to rewrite the image that you want to keep for a long time, so it is sufficient for the storage medium to have several times of rewriting, but conversely it is used as a buffer memory to temporarily record the image For example, when it is desired to use a storage medium, tens of thousands of rewrites are necessary. Therefore, the user may select a different storage medium according to the purpose of use. Even in such a case, as described above, the information for identifying the type of the recording medium or the maximum number of rewrites of the recording medium and the remaining number of rewritable times are detected, and the optimum predetermined number of times of writing is determined accordingly. Because there is a setting on the side, even if a different memory card is installed in the camera, there will be no problem. In this way, the present invention can be applied to all devices that count the number of rewrites regardless of the number of rewrites possible.

  Up to now, the case where the writing / reading control unit 301 is built in the memory card has been described. However, as described above, if the CPU 201 of the camera body is assigned the function of this control unit, the memory card can be used. Furthermore, it can be supplied at a low cost. Also, in the flowcharts of FIGS. 4 and 5, it has been described that the number of rewritable times, formatting impossible, etc. and warnings are displayed only once, but since these information are written in the information recording area, the user confirms You can check it at any time you wish.

  Further, the image and audio data recording unit has been described as a memory card that can be attached to and detached from the camera so far. However, a configuration in which a finite rewritable medium is fixed in the camera body is also possible. In that case, it is possible to supply a very inexpensive digital camera to the user by limiting the shooting function to the minimum.

  Furthermore, the present invention can be applied not only to a semiconductor storage medium as a storage medium but also to an optical disk such as a CD-RW, DVD-RAM, or MO, a magneto-optical disk, or other cameras that use a recording medium with a limited number of rewrites. Easy. Of course, the present invention can be easily applied to a general information processing apparatus other than a camera.
