  The present invention relates to an information processing apparatus, and more particularly to an information processing apparatus that displays a list of files in a format including images and displays a file selection screen that allows a user to select a file.

  In the information processing apparatus, various functions are realized, and with the realized functions, various processes are performed on the files held by the information processing apparatus. For example, a process of deleting a file designated by the user or displaying a plurality of still image files designated by the user as a slide show is performed. To determine which file is processed, it is necessary to display a list of files on the file selection screen and allow the user to select a file.

  When displaying a list of files on the file selection screen, the file may be displayed in a format including an image so that the user can easily understand the contents of the file. For example, when the file is a still image file, a thumbnail image obtained by reducing the still image is displayed. When the file is a moving image file, a title image held in advance may be displayed.

However, if the number of files displayed in a list format including images increases, it will not be possible to display on one screen, so a scroll bar is displayed on the screen, and there are files that cannot be displayed on one screen to the user. In addition, it is necessary to be able to scroll the file list screen (see, for example, JP-A-2005-275034).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments described below do not limit the technical scope of the present invention.

[First Embodiment]
FIG. 1 is a block diagram for explaining the internal configuration of the information processing apparatus 10 according to the present embodiment. As shown in FIG. 1, an information processing apparatus 10 according to this embodiment includes a CPU (Central Processing Unit) 20, a RAM (Random Access Memory) 22, a hard disk drive 24, a memory card interface 26, and a speaker output. A circuit 28 is provided, which are connected to each other via an internal bus 30. The speaker output circuit 28 is a circuit for outputting music and sound. In the present embodiment, BGM at the time of still image display and sound at the time of moving image reproduction are output.

  The CPU 20 includes a ROM (Read Only Memory) 40 and a DSP (Digital Signal Processor) 42. The DSP 42 performs processing for compressing data files such as still images, moving images, and music, and decompressing the compressed data files.

  Further, the CPU 20 is connected to a display controller 52 via a dedicated bus 50, and this display controller 52 is further connected to a display screen 54. That is, when the CPU 20 transmits image data to be displayed to the display controller 52 via the dedicated bus 50, the display controller 52 controls the display screen 54 based on the image data, and displays the display screen 54. indicate. In the present embodiment, the display screen 54 is configured by an LCD. For example, a still image display or a moving image playback is performed, and a file selection screen described later is displayed.

  In addition, the information processing apparatus 10 according to the present embodiment includes a television output circuit 60 connected to the CPU 20. For this reason, if a user connects a television image output cable to a connector (not shown) of the information processing apparatus 10, the user can view still images, moving images, and sounds output by the CPU 20 on a home television.

  In addition, a memory card 70 is appropriately attached to the information processing apparatus 10. Various types of files stored in the memory card 70 attached to the information processing apparatus 10 can be captured by the information processing apparatus 10 via the memory card interface 26. Specifically, the file stored in the memory card 70 is captured by the CPU 20 via the memory card interface 26 and stored in the hard disk drive 24. Particularly in the present embodiment, the hard disk drive 24 stores, for example, still image files and moving image files.

  In this embodiment, the information processing apparatus 10 is assumed to be a photo viewer that is a portable storage device. However, the information processing apparatus 10 is connected to a desktop personal computer, a notebook personal computer, a mobile phone, or the like. It can also be configured.

  FIG. 2 is a plan view of the information processing apparatus 10 according to the present embodiment as viewed from the display screen 54 side. As shown in FIG. 2, on the right side of the display screen 54, there are provided a menu button B10, an enter button B12, and a cancel button B14 that the user operates with a finger. In addition, an upper movement button B20, a left movement button B22, a right movement button B24, and a lower movement button B26 that are operated by the user with a finger are also provided.

  The menu button B <b> 10 is an operation button for displaying various menu screens on the display screen 54. The decision button B12 is an operation button that is pressed when finalizing the operation content when various operations are performed. In the present embodiment, this determination button B12 is pressed particularly when the user moves the cursor on the file selection screen and selects the file on which the cursor is located from the plurality of displayed files. Button.

  The cancel button B14 is an operation button that is pressed when various settings are performed on the menu screen or the file selection screen, and the instruction content is not reflected in the end. The upper movement button B20, the left movement button B22, the right movement button B24, and the lower movement button B26 are operation buttons for moving the cursor to the upper side, the left side, the right side, and the lower side, respectively, on the file selection screen. .

  FIG. 3 is a flowchart for explaining the contents of the file selection process executed by the information processing apparatus 10 according to the present embodiment. This file selection process is realized by the CPU 20 reading and executing a file selection program stored in the ROM 40 in the CPU 20.

  This file selection process is a process that is started when a file needs to be selected by a user operation. For example, the process is executed when the user selects the file to be deleted after selecting the operation of deleting the file on the menu screen.

  As shown in FIG. 3, when this file selection process is started, the information processing apparatus 10 acquires the number of files to be displayed (step S100). That is, the number of files when a user selectable file is displayed in a list format is acquired. Normally, this number of files is the same as the number of files stored in the folder specified by the user.

  Next, the information processing apparatus 10 calculates the number of screens X by dividing the number of files acquired in step S100 by the number that can be displayed on one screen (step S102). In the present embodiment, for example, the number that can be displayed on one screen is “15”.

  Next, the information processing apparatus 10 determines whether the screen number X calculated in step S102 is greater than 1 (step S104). That is, when the number of screens X is larger than 1, it means that not all files can be displayed on one screen, so that all the files can be displayed on one screen according to the value of the number of screens X. I know if it is.

  Therefore, the information processing apparatus 10 next determines whether or not the screen number X is greater than 1 (step S104). If the screen number X is greater than 1, the information processing apparatus 10 calculates the length and position of the scroll box displayed on the scroll bar (step S106). That is, since the screen number X is larger than 1, the scroll bar SBR is displayed on the file selection screen W10. Therefore, the length and position of the scroll box SBX displayed on the scroll bar SBR are calculated.

  In the present embodiment, the length of the scroll box SBX is inversely proportional to the number of files to be displayed on the file selection screen W10. That is, when the number of files to be displayed is large, the length of the scroll box SBX is shortened. Conversely, when the number of files to be displayed is small, the length of the scroll box SBX is increased. In the present embodiment, when the maximum length of the scroll box SBX (that is, the length of the scroll bar SBR) is 1, the length of the scroll box SBX is determined by 1 / number of screens X.

  The position of the scroll box SBX in the scroll bar SBR indicates where the currently displayed screen is located in the entire file list on the file selection screen W10. Therefore, the length and position of these scroll boxes SBX are calculated in this step S106.

  Next, the information processing apparatus 10 displays the file selection screen W10 on the display screen 54 and allows the user to select a file (step S108). FIG. 4 is a diagram showing an example of the file selection screen W10 displayed on the display screen 54 at this time. As shown in FIG. 4, in this embodiment, a list of files is displayed in a format including images. That is, one file is displayed by one thumbnail image and file name. In the example of FIG. 4, since 5 × 3 = 15 files can be displayed on one screen, the displayable number on one screen is “15”. Here, the display position of each file is based on F (1,1) to F (5,3), with the X coordinate being 1 to 5, the Y coordinate being 1 to 3, with the coordinate position at the upper left as a reference. I will express it.

  In the example of FIG. 4, not all files can be displayed on one screen, so a scroll bar SBR is displayed along the right end of the file selection screen W10. A scroll box SBX is displayed inside the scroll bar SBR. As described above, by displaying the scroll bar SBR, the user can know that there is a file that can be selected in addition to the files displayed on the one screen, and the entire file can be selected. You can also find out where the currently displayed file list is located.

  In the present embodiment, the scroll bar SBR is displayed so as to partially overlap the image of the rightmost file. That is, the scroll bar SBR is displayed over the image and the file name of the file at the position of F (5,1), F (5,2), F (5,3). By doing so, in the present embodiment, a list of files can be displayed using the display screen 54 effectively. In other words, the display of thumbnail images and file names of each file is made as large as possible.

  In addition, a cursor CR for pointing to a file is displayed on the file selection screen W10. The cursor CR can be freely moved to the upper side, the left side, the right side, and the lower side by pressing the upper movement button B20, the left movement button B22, the right movement button B24, and the lower movement button B26, respectively. Therefore, the user operates the movement buttons B20, B22, B24, and B26 to move the cursor CR to the target file. Then, when the cursor CR is positioned on the target file, for example, when the determination button is pressed, the file can be selected.

  In addition, when the user presses the upper movement button B20 in a state where the cursor CR is positioned on the top line, the file list can be scrolled upward. In other words, when the cursor CR is on F (1,1) to F (5,1), the upper movement button B20 is pressed to display at the position of F (1,1) to F (5,1). The image and file name of the file that has been moved to the position of F (1,2) to F (5,2) one line down, and to the position of F (1,1) to F (5,1). Displays the image and file name of the previous line that was not displayed so far. Note that the same operation is performed when the user presses the left movement button B22 while the cursor CR is positioned at F (1, 1).

  On the other hand, when the user presses the lower movement button B26 in a state where the cursor CR is positioned on the bottom line, the file list can be scrolled downward. That is, when the cursor CR is on F (1, 3) to F (5, 3), the lower movement button B26 is pressed to move to the position of F (1, 3) to F (5, 3). The displayed file image and file name move to the position of F (1,2) to F (5,2) on the first line, and the position of F (1,3) to F (5,3). Displays the image and file name of the file one line after that has not been displayed so far. Note that the same operation is performed when the user presses the right movement button B24 while the cursor CR is positioned at F (5, 3).

  Here, in the present embodiment, it is assumed that files are arranged in ascending or descending order of file names. Therefore, by scrolling the file list, when the file names are arranged in ascending order or descending order, the file in the earlier order and the file in the later order are newly displayed in the file list. In the present embodiment, when the file selection screen W10 is first displayed, the cursor CR is set to be at the position of the file F (1, 1).

  Next, as illustrated in FIG. 3, the information processing apparatus 10 determines whether or not the user has moved the cursor CR by pressing these movement buttons B20, B22, B24, and B26 (step S110). If the user has not moved the cursor CR (step S110: NO), the information processing apparatus 10 waits by repeating this step S110.

  On the other hand, if the user moves the cursor CR (step S110: YES), it is determined whether or not the position of the cursor CR has been moved to the position of the file that overlaps the scroll bar SBR (step S112). In the example of FIG. 4, it is determined whether or not the cursor CR has moved to the file at the position of F (5,1), F (5,2), F (5,3).

  If it is determined that the position of the cursor CR does not overlap with the scroll bar SBR (step S112: NO), the process returns to step S106 described above.

  On the other hand, when it is determined that the position of the cursor CR overlaps the scroll bar SBR (step S112: YES), the scroll bar SBR is deleted (step S114). Specifically, as shown in FIG. 5, the scroll bar SBR is displayed above the image or file name of the file at the position of F (5,1), F (5,2), F (5,3). Therefore, the scroll bar SBR is deleted, and the images and file names of the files F (5,1), F (5,2) and F (5,3) below the scroll bar SBR are displayed. Can be confirmed. And it returns to step S110 mentioned above.

  On the other hand, when it is determined in step S104 described above that the number of screens X is not greater than 1 (step S104: NO), that is, when it is determined that the number of screens X is 1 or less, the information processing apparatus 10 displays a normal file selection screen without the scroll bar SBR and allows the user to select a file (step S120).

  In the present embodiment, when the user finishes selecting a file, the user presses the menu button B10 to complete the file selection process, and the process designated by the user is executed for the selected file. It is going to be done.

  As described above, according to the information processing apparatus 10 according to the present embodiment, the scroll bar SBR is partially overlapped and displayed on the file image and the file name on the file selection screen W10. By effectively utilizing the screen 54, a large area for displaying information about the file can be secured. Further, since the scroll bar SBR and the image of the file are only partially overlapped, the existence of the file itself can be confirmed by the user on the file selection screen W10.

  Furthermore, in the present embodiment, when the cursor CR moves to a file that overlaps the scroll bar SBR, the scroll bar SBR is deleted, so that it has not been seen below the scroll bar SBR so far. The image and file name of the file become visible, and the user can confirm accurate information about the file.

  In the example described above, the scroll bar SBR is erased in step S114. However, as shown in FIG. 6, the scroll bar SBR may be translucent. That is, when the cursor CR moves to a file that overlaps the scroll bar SBR, the image and file name of the file under the scroll bar SBR may be confirmed to the user in some form.

[Second Embodiment]
In the first embodiment described above, when all the files cannot be displayed on one screen, the scroll bar SBR is displayed to notify the user that there are files that cannot be displayed. In the second embodiment, instead of the scroll bar SBR, a continuous display indicating that a file exists continuously is displayed to notify the user that there are files that cannot be displayed. . Hereinafter, a different part from 1st Embodiment mentioned above is demonstrated.

  FIG. 7 is a diagram illustrating a flowchart for explaining the contents of the file selection process according to the present embodiment, and corresponds to FIG. 3 in the first embodiment described above. As shown in FIG. 7, in the file selection process according to the present embodiment, the process when it is determined in step S104 that the screen number X is greater than 1 is different from the first embodiment described above.

  That is, if it is determined that the screen number X is greater than 1 (step S104: YES), a file selection screen with continuous display is displayed on the display screen 54, and the user is allowed to select a file (step S200). FIG. 8 is a diagram showing an example of the file selection screen W20 displayed on the display screen 54 according to the present embodiment. As shown in FIG. 8, when all the files cannot be displayed on one screen, the continuous display MRK is displayed.

  When this continuous display MRK is displayed on the image of the file at the position of F (1, 1), it indicates that there is a subsequent file before this. Further, when the continuous display MRK is displayed on the image of the file at the position of F (5, 3), it indicates that there is a subsequent file. Therefore, even when there are files that cannot be displayed on one screen, if the file is the first file in the file list, the continuous display MRK is not displayed on the file at the position of F (1, 1). If it is the last file in the file list, the continuous display MRK is not displayed on the file at the position of F (5, 3). These continuous displays MRK are displayed so as to overlap a part of the image of the file.

  Next, the information processing apparatus 10 determines whether the user has moved the cursor CR (step S202). The method of moving the cursor CR is the same as in the first embodiment described above.

  If the user has not moved the cursor CR (step S202: NO), the information processing apparatus 10 repeats this step S202 and waits.

  On the other hand, when the user moves the cursor CR (step S202: YES), it is determined whether or not the position of the moved cursor CR is the position of the file on which the continuous display MRK is displayed (step S204). Specifically, it is determined whether or not the cursor CR is the position of the file of F (1, 1) or the position of F (5, 3).

  If the cursor CR is at the position of the file that does not overlap the continuous display MRK (step S204: NO), the process returns to step S200 described above.

  On the other hand, when CR is the position of the file overlapping the continuous display MRK (step S204: YES), the continuous display MRK is erased (step S206). Specifically, as shown in FIG. 9, when the cursor CR is at the position F (5, 3), the continuous display MRK displayed on the upper side of the image of the file F (5, 3) is displayed. Erasing is performed so that the image of the file of F (5, 3) under the continuous display MRK can be confirmed. Similarly, when the cursor CR is at the position of F (1, 1), the continuous display MRK displayed above the image of the file of F (1, 1) is deleted, and the bottom of the continuous display MRK. The image of the file of F (1,1) in can be confirmed. And it returns to step S110 mentioned above.

  As described above, according to the information processing apparatus 10 according to the present embodiment, in the file selection screen W20, when all the files cannot be displayed on one screen, the continuous display means that there are subsequent files. The MRK is displayed superimposed on the image of the first and / or last file to notify the user that there is a subsequent file. Therefore, it is possible to effectively use the small display screen 54 and secure a large area for displaying information related to the file.

  In addition, when the cursor CR moves to a file that is displayed with the continuous display MRK overlapped, the continuous display MRK is erased. The part of the image can be confirmed, and the user can be informed of accurate information about the file.

  In the above example, the continuous display MRK is erased in step S206. However, as shown in FIG. 10, the continuous display MRK may be made translucent. That is, when the cursor CR moves to a file displayed with the continuous display MRK overlapped, the image of the file under the continuous display MRK may be confirmed to the user in some form.

[Third Embodiment]
In the first and second embodiments described above, a list of files is displayed on a single screen for the user by displaying a control display such as a scroll bar SBR or continuous display MRK on a part of the image of the file. In the third embodiment, by changing the color of the image frame of the first and / or last file image, a list of files is displayed on one screen and is beautiful. It is to notify that there is no. Hereinafter, a different part from 1st Embodiment mentioned above is demonstrated.

  FIG. 11 is a diagram illustrating a flowchart for explaining the contents of the file selection process according to the present embodiment, and corresponds to FIG. 3 in the first embodiment described above. As shown in FIG. 11, in the file selection process according to the present embodiment, the process in the case where it is determined in step S104 that the screen number X is larger than 1 is different from the first embodiment described above.

  That is, when it is determined that the screen number X is greater than 1 (step S104: YES), a file selection screen W30 as shown in FIG. 12, for example, is displayed on the display screen 54 (step S300).

  Next, the information processing apparatus 10 determines whether a file exists before the first file currently displayed on the display screen 54 (step S302). That is, it is determined whether the file exists before the file at the position of F (1,1).

  If the file exists before the first file currently displayed on the display screen 54 (step S302: YES), the color of the image frame of the image of the first file is changed (step S304). For example, in this embodiment, since the color of the image frame displayed in step S302 is white, the color of the image frame of the first file is changed to red in step S304.

  On the other hand, if the file does not exist before the first file currently displayed on the display screen 54 (step S302: NO), the process of step S304 is passed.

  Next, the information processing apparatus 10 determines whether a file exists after the last file currently displayed on the display screen 54 (step S306). That is, it is determined whether the file exists after the file at the position F (5, 3).

  If the file exists after the last file currently displayed on the display screen 54 (step S306: YES), the color of the image frame of the image of the last file is changed (step S308). For example, in the present embodiment, the color of the last image frame is changed from white to red as in step S304 described above. Here, the color of the last image frame and the color of the first image frame are set to the same red, but the colors of both may be different.

  On the other hand, if the file does not exist after the last file currently displayed on the display screen 54 (step S306: NO), the process of step S308 is passed.

  Next, the information processing apparatus 10 determines whether the user has moved the cursor CR (step S310). The method of moving the cursor CR is the same as in the first embodiment described above.

  If the user has not moved the cursor CR (step S310: NO), this step S310 is repeated to wait.

  On the other hand, when the user moves the cursor CR (step S310: YES), the process returns to step S300 described above, and the file selection screen W30 is displayed again based on the position of the moved cursor CR.

  As described above, according to the information processing apparatus 10 according to the present embodiment, when all the files cannot be displayed on one screen in the file selection screen W30, the user is informed that there are files that cannot be displayed. As can be seen, the image frame of the first and / or last file is displayed in a different color from the image frames of the other files. Therefore, it is possible to effectively use the small display screen 54 and secure a large area for displaying information related to the file.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in the above-described embodiment, the example in which the cursor CR is used as the instruction unit for the user to point to the file has been described. However, the instruction unit is not limited to the cursor CR. For example, a pointing device such as a mouse may be used as the instruction means.

  In addition, the files displayed in a list including images are not limited to still image files and moving image files, and can be applied to various types of files.

  The triangular continuous display shown in the third embodiment is merely an example of the form of continuous display, and the continuous display can be realized in various forms such as an arrow or a star. Furthermore, the control display is not limited to the scroll bar SBR and the continuous display MRK described above, and it is possible to notify the user that there are files that cannot be displayed in various ways.

  Further, regarding the file selection process described in the above-described embodiment, a program for executing this process is recorded on a recording medium such as a flexible disk, a CD-ROM (Compact Disc-Read Only Memory), a ROM, a memory card, or the like. Thus, it can be distributed in the form of a recording medium. In this case, the above-described embodiment can be realized by causing the information processing apparatus 10 to read and execute the program recorded on the recording medium.

  Further, the information processing apparatus 10 may include other programs such as an operating system and another application program.
