Description

  The present invention relates to an information processing apparatus, method, and program, and more particularly to a technique for deleting and restoring information used in an information processing apparatus such as a printer apparatus that supports a plurality of external storage media of different standards.

  With the widespread use of camera-equipped mobile phones and digital cameras, there are many opportunities to store image data in small storage media such as SD (Secure Digital) cards, CF (Compact Flash (registered trademark)) cards, and memory sticks. In addition, the capacity of the storage medium is increasing year by year.

  In the past, these storage media have been used as temporary data storage means, but with the increase in capacity, the number of users who operate the storage media as master storage has increased. Previously, it was a common operation to store necessary image data in a personal computer with a larger storage capacity, but the situation that the user group has become popular with non-computer users also has an effect. is doing.

  On the other hand, in a mobile phone with a camera and a digital camera, various storage media as described above have been used depending on the release date and the intention of the manufacturer. Accordingly, printer apparatuses that print these images have been required to support a plurality of storage media of different standards, and have been manufactured to cope with them. In addition, many current printer apparatuses are equipped with a liquid crystal display device with a high pixel in the main body, and a user can refer to an image in a storage medium by using the liquid crystal display apparatus. Some products can also delete the image.

  By the way, a user with little computer use experience may be ambiguous about the concept of a file. In view of such a case, in many camera-equipped mobile phones and digital cameras, handling of image files, particularly deletion of files, is generally performed through some confirmation operation for the user. Along with this, in the printer apparatus, when deleting a file, it is adopted that the user deletes after confirming some confirmation to the user.

To do.

<Displaying image data>
The user first presses the power button 202 to activate the system. In this case, the input member control unit 101 notifies the CPU 102 that there has been an activation instruction. The CPU 102 sequentially executes system programs in the internal storage device (flash memory) 107 to initialize a series of systems. After that, the system program mounts only the external storage medium having the highest priority in the priority order of the SD card 161, the memory stick 162, and the CF card 163 from the currently mounted external storage media through the external storage medium control unit 106. Here, the mount means an electrical connection.

  After mounting the external storage medium, the system program scans the files in the mounted external storage medium and finds data recognized as image data, and then reads the image data read through the external storage medium control unit 106. The data is expanded on the main storage device 103. Further, after being converted into image data for display, the image data is developed on a display VRAM disposed on the main storage device 103, and an image is displayed on the liquid crystal display device 209.

<Erase image data>
The DELETE button 210 is currently displayed on the liquid crystal display device 209 by an operation from the user, and erases an image in the currently mounted external storage medium through the external storage medium control unit 106. As described above, the printer apparatus according to the present embodiment has slots corresponding to three different types of external storage media under the control of the external storage medium control unit 106. Here, when a plurality of external storage media are loaded in the slot at the same time, the highest priority external storage media is mounted based on a predetermined priority order. In the case of such an aspect, there is a possibility that deletion is performed on an unintended external storage medium due to erroneous recognition by the user. Therefore, in the printer device according to the present embodiment, a deletion file saving buffer is provided in the internal storage device 108 for each standard format of the external storage medium, and a mechanism for reducing the possibility of unintentional deletion of an image file due to a user's erroneous operation is provided. ing. The details will be described below.

  FIG. 4 is a diagram showing a state of the deleted file saving buffer in the internal storage device 108. In the internal storage device 108 shown in FIG. 4, reference numerals 402, 403, and 404 are deletion file save buffers, which are constructed in a part of the storage area of the internal storage device 108. The deleted file saving buffer corresponds to a configuration example of the internal storage area in the present invention.

  In the printer apparatus according to the present embodiment, the deletion file saving buffers 402 to 404 are prepared for each standard format of the external storage medium. This is to reduce the possibility that the automatic restoration operation of the image file to be deleted, which will be described later, will cause confusion to the user by ensuring the relevance with the external storage medium to be deleted. In this embodiment, as shown in FIG. 4, 402 is a deletion file saving buffer for SD, 403 for memory stick (MS), and 404 for CF.

  Here, FIG. 4 shows a state in which the SD card 161, the memory stick 162, and the CF card 163 are inserted into the printer device. Further, as described above, it is assumed that the system program mounts the SD card 161 according to the mount priority of the external storage medium. In the SD card 161, 406 is an image file, and an image corresponding to the image file 406 is currently displayed on the liquid crystal display device 209. In this embodiment, when pressing of the DELETE button 210 is detected in this state, the image file 406 is copied (copied) to the deletion file saving buffer 402 for the SD card 161 as shown in FIG. A corresponding image file 409 is temporarily stored. After that, the image file 406 in the SD card 161 is deleted.

<About image forward / back display>
Here, image advance and return display will be described. When a plurality of image data is stored in the mounted external storage medium, the system program reads the next image data from the external storage medium control unit 106 when it detects that the image feed button 205 is pressed, and is described above. Then, the data is output to the liquid crystal display device 209. On the other hand, when the system program detects that the image return button 206 is pressed, the system program selects the image in the opposite direction to the image advance button 205 and performs the same operation. Further, when an image file is copied in the deleted file saving buffer described above, the image in the deleted file saving buffer is also selected as an image selection target. Specifically, when the image in the external storage medium reaches the last image with the image advance button 205, the image in the deletion file save buffer corresponding to the currently mounted external storage medium standard is selected as the selection target. To be.

  This image feeding operation will be described in more detail with reference to FIG. It is assumed that immediately after mounting, the first image 501 in the external storage medium is read and displayed on the liquid crystal display device 209 as described above. In this state, when the system program detects that the image feed button 205 is pressed, the second detected image 502 in the external storage medium is displayed. Thereafter, the same operation is repeated every time the image feed button 205 is pressed. . Then, after the last image 503 in the external storage medium becomes the display target, if the pressing of the image advance button 205 is further detected, the first detected first in the deleted file save buffer of the mounted external storage medium described above. The image 504 is set as a display target. Thereafter, the image in the deletion file saving buffer is repeated in order of the image 505 and then the next time every time the image feed button 205 is detected. When the display target image becomes the final image 506 in the deletion file saving buffer, the first image on the external storage medium is set as the display target again. That is, in the present embodiment, when displaying an image, it is possible to refer to an image file copied to a deletion file saving buffer corresponding to the mounted external storage medium.

  In addition, when the image return button 206 is operated, except for the image 501 being the first display image immediately after mounting, the deletion in the external storage medium and in accordance with the mounted external storage medium is performed in the reverse order of the above operation. Select an image in the file save buffer.

<About the number of prints>
Next, the print number setting buttons 203 and 207 set the number of prints of an image currently displayed on the liquid crystal display device 209 in accordance with a user operation. That is, the system program increases the number of prints by one when detecting the press of the print number setting button 203, and conversely decreases the print number by one when detecting the press of the print number setting button 207.

<Editing the displayed image>
The STAMP button 208 sets the stamp image to be superimposed on the image displayed on the liquid crystal display device 209. That is, when the system program detects that the STAMP button 208 is pressed, the system program shifts to the stamp editing mode and simultaneously operates the display storage area arranged in the main storage device 103. Then, as shown by 301 in FIG. 3, an overlay display is performed on the image on which the stamp image has already been displayed on the liquid crystal display device 209.

  Further, in the stamp editing mode, the system program detects that the image return button 206 is detected, the displayed stamp image is on the left, the image advance button 205 is detected on the right, and the number of print setting buttons 203 and 207 are detected on the top and bottom. The display position can be moved.

<About printing the selected image>
The print button 204 executes printing of an image currently displayed on the liquid crystal display device 209 in accordance with a user operation. That is, when the system program detects that the print button 204 has been pressed, if it is in the stamp edit mode, the system program cancels this and expands the currently displayed image into print format data on the main storage device 103. Then, the printing control unit 105 is activated for printing operation.

<Automatic restoration of deleted data>
Next, the automatic restoration operation of the deleted file of the printer apparatus according to this embodiment will be described. In the above, the stamp editing operation and the print execution operation have been described. Here, in the printer device according to the present embodiment, an image file exists in the deleted file saving buffer corresponding to the currently mounted external storage medium, and the user can display the image file by the user's image sending / returning operation. When the stamp editing operation or printing execution operation is performed, the image is restored to the currently mounted external storage medium. This is because even if the file is a deletion target, it may be a file useful for the user when there is an act of performing the stamp editing and printing execution by the user. This operation will be further described with reference to FIG.

  When the user performs a printing operation or stamp editing processing, the system program restores the deleted image data to the storage medium if necessary according to the flowchart shown in FIG.

  First, in step S601, the system program determines whether the currently selected image, that is, the image displayed on the liquid crystal display device 209 is from an external storage medium or a deletion / saving buffer. If the image is based on the image file on the external storage medium, the process advances to step S605 to execute stamp editing processing or printing processing. On the other hand, if the selected image is an image file derived from the deletion file saving buffer, the process proceeds to step S602.

  In step S602, the system program reads the target file from the deleted file saving buffer, restores it to the currently mounted external storage medium in step S603, and deletes the image file in the selected deleted file saving buffer in step S604. Then, the process proceeds to step S605, and stamp edit processing or print processing is executed.

  The printer device according to the present embodiment has been described above. In other words, in the printer device according to the present embodiment, when a file in the external storage medium is designated for deletion, the file is temporarily stored in the deletion file save buffer, and the file designated for deletion is printed. When an instruction is given, the data is restored to the external storage medium. With such a configuration, even when there is an erroneous operation by the user regarding file deletion, the file can be easily restored, and useful files can be protected. In other words, if a file once deleted is considered a useful file for the user, it will be restored without any special operations, so that the useful file will be protected. Can reduce the possibility of unintended file deletion.

  In the embodiment of the present invention described above, the restoration from the deleted file saving buffer is performed when printing is designated for the image in the deleted file saving buffer with respect to the printing operation. As another aspect, a method of performing the restoration operation when the image is designated to be printed more than a certain number in order to avoid the restoration operation not intended by the user can be considered.

  In the present embodiment described above, the deletion processing data saving operation and the automatic restoration operation of the printer apparatus can be invalidated by user settings. In this case, the deletion process by pressing the DELETE button 210 does not perform the saving operation to the deletion file saving buffer.

  In the embodiment described above, the deletion file saving buffer is typically secured on the NVRAM of the internal storage device 108. Alternatively, any hardware configuration that does not employ NVRAM can be applied by using the main storage device 103. In particular, when the main storage device 103 is used, care should be taken not to compress the storage area by compressing and copying the save file. Even if the image is compressed, the image is compressed so as not to affect the print quality of the printer.

  In this embodiment, an example in which the present invention is applied to a printer apparatus has been described. However, the present invention can also be applied to an information processing apparatus such as a personal computer. In this case, file protection can be achieved not only for image files but also for files related to documents and graphics, for example.

  In addition, a recording medium in which a program code of software for realizing the functions of the present invention is recorded may be supplied to a system or apparatus, and the system may read and execute the program code stored in the recording medium.

  In this case, the program code itself read from the recording medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.

  As a storage medium for supplying the program code, for example, a magneto-optical disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, ROM, DVD, or the like can be used.

  Further, it is also included that the OS or the like running on the computer performs part or all of the actual processing based on the instruction of the program code, and the functions of the above-described embodiments are realized by the processing. Needless to say.

  Furthermore, it goes without saying that the CPU of the function expansion board or the like performs part or all of the actual processing based on the instruction of the program code, and the functions of the above-described embodiments are realized by the processing. Yes.
