Description

  The present invention relates to an information display device, an information display method, an information display program, and an endoscope system that display electronic files and folders or directories, and in particular, display electronic files in the same folder or directory simultaneously in different formats. Regarding technology.

  2. Description of the Related Art Conventionally, in an information display device as a device incorporating image browsing software in a personal computer or the like, to classify and organize electronic files such as electronic document files and electronic image files on a storage medium (storage device) such as a hard disk or a flexible disk. A folder (or directory) is created and each electronic file is stored in the folder. In this folder, not only each electronic file but also another folder can be stored as a subfolder. These folders, subfolders (or subdirectories), and electronic files are usually classified and managed hierarchically.

  These hierarchically classified and managed folders and subfolders are hierarchically displayed in a predetermined area so that the hierarchical structure can be easily recognized visually, or stored in any specified folder or subfolder. The subfolders or electronic files that have been displayed are displayed in a list within a predetermined area (for example, see Patent Document 1).

FIG. 8 is a diagram showing a display example of a conventional information display device displaying thumbnail images.
As shown in FIG. 8, the conventional information display device displays a main window 11 as a display window on its display screen 10. The main window 11 includes a folder tree area 13 and a content area 90 in addition to the various toolbars 12, and displays the folder tree area 13 and the content area 90 simultaneously.

  In FIG. 8, the folder tree area 13 displays the hierarchically managed folders in a hierarchical manner. The folder name “100IV7R1” is highlighted with a folder name for clearly indicating that the folder is designated.

  In the content area 90, a limited number of nine electronic files among the electronic files in the folder designated in the folder displayed hierarchically in the folder tree area 13 are listed in thumbnail format.

FIG. 9 is a diagram showing a display example of a conventional information display device displaying file names.
The user can switch the display in the content area 90 to a list display of a large number of file names as shown in FIG. 9 by performing a specific operation using the toolbar 12.

  The display in the thumbnail format displayed in the content area 90 of FIG. 8 is convenient because the user can know what image each file is. However, since the thumbnail format occupies a certain area for each file, the number of thumbnails that can be displayed in the limited content area 90 is very limited. It is often impossible to display all electronic files in a specified folder. In such a case, thumbnails of all electronic files are sequentially displayed by operating the scroll bar. Further, although the performance of personal computers has improved today, thumbnails are images, and a certain amount of processing time is required to display a plurality of thumbnails. Therefore, if the user wants to execute a specific electronic file and the thumbnail is not currently displayed in the content area 90, the user must first scroll the thumbnail to display the desired electronic file. . In this operation, the user must wait for the time required for processing by the personal computer.

On the other hand, when switching to the file name list display as shown in FIG. 9, the file name is displayed almost instantaneously. Even if there are a large number of electronic files in the designated folder, the area occupied by each file name is small, so a large number of file names can be displayed at once. Even if all the electronic files in the specified folder cannot be displayed at once, and the scroll bar must be displayed and scrolled, the operation is performed at a very high speed. Therefore, when the file name list display as shown in FIG. 9 is used, the user cannot know what image each file is, but when the user wants to execute a specific electronic file, the operation is as follows. It can be executed in a very short time.

  However, in the information display device as described above, when displaying a list of subfolders or electronic files stored in a specified folder or subfolder within a predetermined area, the information display device is limited depending on the purpose of use of the user. Either thumbnails of a reduced number of images or icons are displayed as a list, or many file names without thumbnails are displayed as a list, and thumbnail list display and file name list display are displayed simultaneously. There was a problem that it was not possible.

  The present invention has been made in view of the above circumstances, and when displaying a list of subfolders or electronic files stored in a designated folder or subfolder, a limited number of thumbnails in a predetermined area are displayed. An object is to provide an information display device, an information display method, and an information display program capable of simultaneously displaying a list display and a list display of a large number of file names without thumbnails in a predetermined area.

The present invention employs the following configuration in order to solve the above problems.
That is, according to one aspect of the present invention, the information display device of the present invention displays an electronic file that can be processed by a computer or a folder that indicates a folder where the electronic file is conceptually recorded on a recording medium. A folder display means for hierarchically displaying the folders managed hierarchically in a first display area; and thumbnails of electronic files in the designated folder among the folders displayed hierarchically by the folder display means. Thumbnail display means for displaying a list in the second area in a format, and a file for displaying a list of electronic files in a designated folder among the folders displayed hierarchically by the folder display means in a third area in a file name format Name display means.

In the information display device of the present invention, it is preferable that a boundary between the second display area and the third display area is variable.
In addition, the information display device of the present invention designates an arbitrary electronic file listed in either the second display area or the third display area, and the corresponding electronic file is displayed in the second display area. It is desirable to display in the other of the area or the third display area.

  In the information display device of the present invention, when the corresponding electronic file is displayed in the other of the second display area or the third display area, it is clearly indicated that the corresponding file is designated. It is desirable.

  In the information display device of the present invention, it is desirable that when an execution instruction is given for an arbitrary electronic file displayed in the second display area or the third display area, the execution-instructed electronic file is executed. .

  According to another aspect of the present invention, the information display method of the present invention is an information display device that displays a computer-processable electronic file or a folder indicating a location where the electronic file is conceptually recorded on a recording medium. The hierarchically managed folder is hierarchically displayed in a first display area, and the electronic files in the designated folder among the hierarchically displayed folders are displayed in a thumbnail format in the second format. And a list of electronic files in a designated folder among the folders displayed in the hierarchy are displayed in a third area in a file name format.

  According to another aspect of the present invention, an information display program according to the present invention displays an electronic file that can be processed by a computer or a folder that indicates a folder where the electronic file is conceptually recorded on a recording medium. A folder display means for hierarchically displaying the folders managed hierarchically in a first display area, and thumbnails of electronic files in the designated folder among the folders displayed hierarchically by the folder display means Thumbnail display means for displaying a list in the second area in a format, and a file for displaying a list of electronic files in a designated folder among the folders displayed hierarchically by the folder display means in a third area in a file name format An information display program for functioning as name display means.

  According to the present invention, when displaying a list of subfolders or electronic files stored in a designated folder or subfolder, a list of a limited number of thumbnails in a predetermined area and thumbnails in the predetermined area are displayed. It is possible to display a list of a large number of file names that are not present at the same time.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining the outline of the present invention.
An information display device to which the present invention is applied displays an electronic file or a folder indicating a location where the electronic file is conceptually recorded on a recording medium. Here, the electronic file refers to an electronic document file or an electronic image file that can be processed by a computer such as a personal computer.

  And this information display apparatus displays the main window 11 as a display window on the display screen 10, as shown in FIG. In addition to the toolbar 12, the main window 11 includes a folder tree area 13, a thumbnail area 14, and a file area 15, and these folder tree area 13, thumbnail area 14, and file area 15 are displayed simultaneously.

  In FIG. 1, the folder tree area 13 displays the hierarchically managed folders. The folder name “100IV7R1” is highlighted to clearly indicate that it has been designated.

  In the thumbnail area 14, the electronic files in the designated folder among the folders displayed hierarchically in the folder tree area 13 are listed and displayed in a thumbnail format.

  In the file area 15, the electronic files in the designated folder among the folders displayed hierarchically in the folder tree area 13, that is, the electronic files listed in the thumbnail format in the thumbnail area 14 are filed. Listed in name format.

  The boundaries among the folder tree area 13, the thumbnail area 14, and the file area 15 can be moved using, for example, a mouse device. Due to the movement of the boundary, the shape or size of the folder tree area 13, the thumbnail area 14, or the file area 15 changes, and an optimal layout can be achieved.

  For example, when the folder hierarchy displayed in the folder tree area 13 is deep, there is a request to enlarge the folder tree area 13, and when the folder hierarchy displayed in the folder tree area 13 is not deep, etc. There is no need to enlarge the folder tree area 13. Further, when there are a large number of electronic files to be displayed in the thumbnail area 14 or the file area 15, there is a demand to enlarge the thumbnail area 14 or the file area 15, and the thumbnail area 14 or the file area 15 should be displayed. When the number of electronic files is small, there is no need to enlarge the thumbnail area 14 or the file area 15. Therefore, not only the boundary between the folder tree area 13 and the thumbnail area 14 and the boundary between the folder tree area 13 and the file area 15, but also the boundary between the thumbnail area 14 and the file area 15 can be changed.

  As described above, since the boundaries between the folder tree area 13, the thumbnail area 14, and the file area 15 are variable, for example, as shown in the thumbnail area 14 of FIG. 1, they are stored in a folder having the folder name “100IV7R1”. You may not be able to display all of your electronic files. In such a case, any electronic file stored in the folder with the folder name “100IV7R1” can be displayed in the thumbnail area 14 using the scroll bar.

  Incidentally, the thumbnail area 14 and the file area 15 are independent of each other. Therefore, the electronic file displayed in the thumbnail area 14 is not always displayed in the file area 15. For example, a thumbnail image with the file name “IV7I1033.JPG” is displayed in the thumbnail area 14 shown in FIG. 1, but the file name “IV7I1033.JPG” is not displayed in the file area 15.

  Even in such a case, when an arbitrary electronic file listed in either the thumbnail area 14 or the file area 15 (for example, the thumbnail area 14) is designated (for example, a single click with a mouse device), the corresponding electronic file is displayed. The file is displayed in the other of the thumbnail area 14 or the file area 15 (in this example, the file area 15). For example, a thumbnail image with a file name “IV7I1027.JPG” is displayed in the thumbnail area 14 shown in FIG. 1, and the thumbnail image is surrounded by a frame to clearly indicate that the electronic file has been designated. The file name “IV7I1027.JPG” is also displayed in the file area 15, and the file name is surrounded by a frame to clearly indicate that this electronic file has been designated.

FIG. 2 is a diagram illustrating an operation state of the electronic file.
The information display device to which the present invention is applied, when instructed to execute an arbitrary electronic file displayed in either the thumbnail area 14 or the file area 15 in the state shown in FIG. The file is executed. For example, when a thumbnail image of the file name “IV7I1027.JPG” displayed in the thumbnail area 14 is instructed to be executed by double-clicking with a mouse device or the like, “IV7I1027.JPG” is an electronic file of a still image. As shown in FIG. 2, the image window 21 is opened, and a still image “IV7I1027.JPG” is displayed in the image window 21. The same applies when the file name “IV7I1027.JPG” displayed in the file area 15 is double-clicked by the mouse device. That is, the user can comfortably instruct execution without wondering which of the thumbnail area 14 or the file area 15 should be instructed to execute.

FIG. 3 is a diagram for explaining the usability of the information display device to which the present invention is applied.
In the state as shown in FIG. 2, that is, in a state where the main window 11 is displayed over the image window 21 by executing an electronic image file or the like, You may want to perform this operation. In such a case, the main window 11 may be switched so that it is displayed on the image window 21, but by changing the size of the main window 11, both the main window 11 and the image window 21 are changed. Can be viewed.

  Even in such a case, as described above, since the boundaries among the folder tree area 13, the thumbnail area 14, and the file area 15 are variable, the usability is very good.

Next, the flow of “information display processing” executed in the information display apparatus to which the present invention is applied will be described.
FIG. 4 is a flowchart showing a flow of “information display processing” executed in the information display apparatus to which the present invention is applied, and FIG. 5 shows a flow of subroutine “window operation processing” in “information display processing”. FIG. 6 is a flowchart showing the flow of a subroutine “file execution process” in the “window operation process”.

First, in step 401 of FIG. 4, it is determined whether or not there is an instruction to open a window according to an instruction from the user.
If it is determined that there is an instruction to open the window (step S401: Yes), the main window 11 to be displayed on the display screen 10 is created in step S402. On the other hand, if it is determined that there is no instruction to open the window (step S401: No), a loop for waiting for an instruction to open the window is entered (return to step S401).

  In step S403, the folder tree area 13 provided in the main window 11 is created. In step S404, the thumbnail area 14 provided in the main window 11 is created. In step S405, the file area 15 provided in the main window 11 is created. .

  Subsequently, in step S406, the main window 11 including the folder tree area 13, thumbnail area 14, and file area 15 created in steps S403 to S405 is opened.

  In step S407, the folder tree area 13 displays the hierarchically managed folders (folder tree display). In step S408, the designated folder is highlighted. As a designated folder, for example, “My Documents” is generally used as an initial value.

  In step S409, the thumbnail area 14 displays a list of electronic files in the designated folder among the folders displayed hierarchically in the folder tree area 13 in a thumbnail format. If the electronic file displayed as a list is not an electronic image file, an icon is displayed instead of the thumbnail image. When all the electronic files cannot be displayed as a list in the thumbnail area 14, a scroll bar is displayed to display only a part of the electronic files.

  In step S410, the file area 15 displays a list of electronic files in the designated folder among the folders hierarchically displayed in the folder tree area 13 in a file name format. When all the electronic files cannot be displayed in a list in the file area 15, a scroll bar is displayed to display only a part of the electronic files.

  As a result, folders are hierarchically displayed in the folder tree area 13, electronic files are listed in thumbnail format in the thumbnail area 14, and electronic files are listed in file name format in the file area 15.

Next, in step S411, it is determined whether or not there is an instruction to close the window according to an instruction from the user.
If it is determined that there is an instruction to close the window (step S411: Yes), the main window 11 is closed in step S412. On the other hand, if it is determined that there is no instruction to close the window (step S411: No), whether or not there has been any operation from the user other than an instruction to close the window on the main window 11 in step S413. Judgment is made.

  If it is determined that any operation has been performed (step S413: Yes), in step S414, a subroutine "window operation process" for executing a process according to the operation from the user is executed. This subroutine “window operation process” will be described in detail with reference to FIG. On the other hand, if it is determined that there is no operation (step S413: No), the process returns to step S411 to wait for an instruction from the user.

Next, the subroutine “window operation process” will be described with reference to FIG.
First, in step S501 in FIG. 5, the instruction from the user includes not only the size of the main window 11 itself but also the sizes of the folder tree area 13, the thumbnail area 14, and the file area 15 included in the main window 11. It is determined whether or not the operation is for changing the size. For example, when the outer frame of the main window 11 is dragged using the mouse device, or the boundary between the folder tree area 13, the thumbnail area 14, and the file area 15 is dragged, the size of the main window 11 is changed. Judged to be an operation.

  If it is determined that the operation is for changing the size of the main window 11 (step S501: Yes), in step S502, the main window 11, the folder tree area 13, and the thumbnail area according to the operation for changing the size. 14 or the size of the file area 15 is changed, and in step S503, the display content is changed according to the changed size.

  If it is determined in step S501 that the operation is not an operation for changing the size of the main window 11 (step S501: No), or after the display content is changed in step S503, an instruction from the user is displayed in step S504. It is determined whether or not this is a change in designation.

  If it is determined that the designation of the folder has been changed (step S504: Yes), the folder whose designation has been changed is highlighted in step S505, and the thumbnail area 14 is highlighted in step S506 in step S505. The displayed electronic files in the changed folder are listed in thumbnail format, and in step S507, the electronic files in the changed folder highlighted in step S505 are listed in the file area 15 in file name format. indicate.

  If it is determined in step S504 that the folder designation has not been changed (step S504: No), or after the list is displayed in step S507, the instruction from the user is an instruction to execute the electronic file in step S508. It is determined whether or not.

  If it is determined that the instruction is for executing the electronic file (step S508: Yes), a subroutine “file execution process” described with reference to FIG. 6 is executed in step S509.

  After that, or when it is determined in step S508 that the instruction is not for file execution processing (step S508: No), in step S510, the instruction from the user is not an operation for closing the main window 11, It is determined whether it is an operation for other processing that is neither an operation for changing a size, an operation for changing a folder, nor an operation for executing a file.

  And when it is judged that it is other operation (step S511: Yes), in step S511, other processing is performed, it returns to step S411 of FIG. 4, and it is judged that it is not other operation ( Step S511: No) also returns to step S411 in FIG. 4 and waits for an instruction from the user.

Next, the subroutine “file execution process” will be described with reference to FIG.
First, in step S601 of FIG. 6, whether or not the instruction from the user has performed a predetermined operation on the electronic files listed in the thumbnail format in the thumbnail area 14, for example, a single click with a mouse device or the like Judge whether or not.

  If it is determined that the operation is a single click (step S601: Yes), in step S602, the single-clicked electronic file (thumbnail image) is explicitly displayed by surrounding it with a rectangle or the like. In step S603, it is determined whether the file name corresponding to the single-clicked electronic file is displayed in the file area 15.

  If it is determined that the file is not displayed (step S603: No), the corresponding file name is displayed by scrolling the file area 15 in step S604. On the other hand, when it is determined that the file is displayed (step S603: Yes), or after displaying the corresponding file name in step S604, in step S605, the corresponding file name is clearly displayed by surrounding it with a rectangle or the like. .

  Next, after the file name is explicitly displayed in step S605, or when it is determined in step S601 that the operation is not a single click operation of the thumbnail image (step S601: No), an instruction from the user is received in step S606. It is determined whether or not a predetermined operation has been performed on the electronic files listed in the file name format in the area 15, for example, whether or not a single click has been performed with a mouse device or the like.

  When it is determined that the operation is a single click (step S606: Yes), in step S607, the single clicked electronic file (file name) is explicitly displayed by surrounding it with a rectangle or the like. In step S608, it is determined whether a thumbnail image corresponding to the single-clicked electronic file is displayed in the thumbnail area 14.

  If it is determined that it is not displayed (step S608: No), in step S609, the corresponding thumbnail image is displayed by scrolling the thumbnail area 14 or the like. On the other hand, if it is determined that it is displayed (step S608: Yes), or after displaying the corresponding thumbnail image in step S609, in step S610, the corresponding thumbnail image is explicitly displayed by surrounding it with a rectangle or the like. .

  Next, after the thumbnail image is explicitly displayed in step S610, or when it is determined in step S606 that the file name is not a single click operation (step S606: No), in step S611, the instruction from the user is a thumbnail. Whether or not a predetermined operation has been performed on the electronic files listed in the thumbnail format in the area 14 or the electronic files listed in the file name format in the file area 15, for example, double-clicked with a mouse device or the like Determine whether or not.

  If it is determined that the operation is a double click (step S611: Yes), in step S612, the double clicked electronic file is activated. For example, if the electronic file is a still image, a still image is displayed. If the electronic file is a moving image, a moving image is reproduced. If the electronic file is an audio image, sound is reproduced.

  Then, after the electronic file is activated in step S612 or when it is determined in step S11 that the operation is not a double click operation (step S611: No), the process proceeds to step S510 of FIG. 5 described above.

FIG. 7 is a diagram for explaining an application example of the information display device to which the present invention is applied.
In one of the toolbars 12 provided in the main window 11 of the information display apparatus to which the present invention is applied (the toolbar 12 displayed under the address bar which is the other one of the toolbars 12), a folder currently designated Alternatively, the modification date of the electronic file is displayed. If a folder is specified and no electronic file is specified, the modification date and time of that folder is displayed. On the other hand, when an electronic file is designated, the modification date and time of the electronic file is displayed. In FIG. 7, “Modified: 10/28/2006” is displayed, which indicates that the modification was made on October 28, 2006. Of course, the time can also be displayed.

  When the electronic file recorded in the folder is an electronic moving image file, an image obtained by reducing the first frame of the electronic moving image file is displayed as a thumbnail image. As described above, when a thumbnail image or a file name is double-clicked, a moving image is reproduced.

  Further, when the electronic file recorded in the folder is an electronic image file having a history of performing stereo measurement by the endoscope apparatus, a measurement icon 71 is displayed, for example, near the lower right corner of the thumbnail image. Thereby, the user can easily find an electronic image file having a result of stereo measurement.

  If the electronic file recorded in the folder is not an electronic image file, a predetermined icon is displayed instead of the thumbnail image. When the icon is double-clicked, the same software as that started when the file name is double-clicked is started, and the electronic file is played back. For example, when the electronic file is an electronic audio file, an icon indicating that the electronic file is an electronic audio file is displayed. When the electronic file is double-clicked, the reproduction software is activated and the audio is reproduced.

  Further, when playing back an electronic audio file, if an electronic still image file having the same file name as the electronic audio file exists, the electronic still image file is displayed on the image window 21 at the same time. For example, when the electronic still image file “IV7I0030.JPG” having the same file name as the electronic audio file “IV7I0030.WAV” is in the same folder, the image window 21 is displayed along with the reproduction of the electronic audio file “IV7I0030.WAV”.
