Description

  The present invention relates to a content display device, a content display method, and a content display program that display a list of a large amount of content.

  2. Description of the Related Art Conventionally, an information processing apparatus that manages and displays content such as a large number of images taken with a digital camera or the like has been proposed (for example, Patent Document 1). The information processing apparatus disclosed in Patent Document 1 is configured as a general personal computer to which a hard disk, a keyboard, a display, and the like are connected, and is shot with a folder list screen that displays a folder in the hard disk in a tree structure, a digital camera, and the like. A thumbnail image list screen for displaying a list of thumbnail images with reduced images is displayed on the display. Then, when one folder is selected on the folder list screen, the information processing apparatus of Patent Literature 1 displays a list of thumbnail images of images stored in the selected folder on the thumbnail image list screen. Further, the information processing apparatus of Patent Literature 1 narrows down thumbnail images to be displayed as a list by searching for an image file based on information such as a shooting date added to the image file in order to make it easier for a user to search for a desired image. .

JP 2006-53871 A

  However, in the information processing apparatus of Patent Document 1, there are two cases where the number of images stored in the folder is 0 and when the search result for narrowing down the thumbnail images to be displayed in a list is 0. As a result, the number of thumbnail images displayed as a list becomes zero, and nothing is displayed on the thumbnail image list screen. If nothing is displayed on the thumbnail image list screen, the user knows whether nothing is displayed because the number of images stored in the folder is 0, or nothing is displayed because the thumbnail images to be displayed in the list are narrowed down. Not only that, but it also becomes anxious whether the information processing device itself is operating normally. Thus, if nothing is displayed on the thumbnail image list screen, the user is confused.

  The present invention has been made paying attention to such a conventional problem. The purpose of the present invention is to reduce the number of thumbnail images displayed in a list to zero even when the thumbnail images displayed in a list are narrowed down. An object is to provide a content display device, a content display method, and a content display program that do not cause confusion.

  In order to solve the above problems, a content display device according to the present invention basically includes a content acquisition unit that acquires a plurality of display contents that are contents to be displayed in a list, and a list display that displays the plurality of display contents as a list. Means for classifying the display content, button display means for displaying a display release button associated with the classification, and the display release button when the display release button is operated. Display cancellation means for canceling the display so that the display contents of the classification are not displayed in a list by the list display means, and the display cancellation means is displayed as a result even if the display cancellation button is operated. The gist is not to cancel the display when there is no display content.

  The content display apparatus according to the present invention displays a list of a plurality of display contents acquired by the content acquisition unit. When the display cancel button associated with the classification for which the classification means classifies the display content is operated, the display cancellation means displays a list of display contents of the classification associated with the display cancel button among the plurality of display contents. Cancel the display so that it will not be. At this time, the display canceling unit does not cancel the display when there is no display content to be displayed as a result of the display canceling.

  In this way, even if the number of display contents to be displayed in a list is narrowed down by operating the display cancel button, it is possible to prevent the number of display contents to be displayed in a list from becoming zero.

  The content display device of the present invention described above further includes mark adding means for adding a mark to the display content, and mark deleting means for deleting the mark from the display content, and the classification is combined with the display content. The mark is displayed and designated by the mark added or deleted by the mark adding means and the mark deleting means.

  In this way, the classifying unit classifies the display content based on the mark added or deleted to the display content by the mark adding unit and the mark deleting unit and displayed together with the display content. Therefore, it is easy to understand the correspondence between the classification and the display content only by looking at the classification displayed in the list, and the mark added to the display content can be changed by the mark addition means and the mark deletion means. For this reason, the display content of the classification associated with the display release button is easy to understand, and the classification can be changed, so that it is easier to narrow down the display content displayed in a list.

  In the content display device of the present invention described above, a folder designating unit that designates a folder in which the plurality of display contents are stored, and a classification storage that stores at least the classification of the display content other than the designated folder. The content acquisition unit acquires the plurality of display contents from the folder designated by the folder designation unit according to the classification stored in the classification storage unit.

  In this way, the display content acquired by the content acquisition unit can be narrowed down by the folder specified by the folder specification unit and the classification stored for each folder.

  In the content display device of the present invention described above, the display cancellation unit sets the number of display contents to be not displayed in a list when the folder designation unit changes the designation of the folder to zero.

  After the display release button is operated, if the list of contents stored in the display content is changed and the list is displayed, the user cannot display the list when the display release button is enabled or the list display when the display release button is disabled. Is likely to be confused. If the number of display contents that are not displayed in a list by the display canceling means is reduced to 0 and the operation of the display cancel button is disabled when the folder is changed, the possibility of causing confusion to the user is reduced. can do.

  In the content display device of the present invention described above, the display cancellation unit has a predetermined priority order for the classification, and the priority order so that the number of display contents displayed as a list is not zero. The display contents of a predetermined category are displayed in a list based on the above.

  In this way, when the display release button is operated, the number of display contents displayed in a list does not become zero, and the user will not misunderstand that the display contents are not stored in the folder.

  In the content display device of the present invention described above, the folder designating unit records an extraction condition for each folder, and the display canceling unit is configured to display the plurality of display contents based on the extraction condition corresponding to the folder. The same display content as when the folder was selected before is not displayed in a list.

  In this way, based on the extraction conditions stored for each folder, it is possible to prevent the display contents displayed in the list when the folder was previously selected from being displayed when the same folder is specified next time. .

  In the content display device of the present invention described above, the display canceling unit may change the designation of the folder by the folder designating unit so that the number of display contents displayed as a list based on the extraction condition is zero. In this case, the extraction condition is not used.

  In this way, even when the extraction condition is specified, it is possible to avoid having zero display contents when the folder specification is changed.

  The content display device of the present invention described above displays an error when the folder designating unit changes the designation of the folder and the number of display contents displayed in a list is zero.

  After the display release button is operated, if the folder in which the display content is stored is changed and the list is displayed while the operation by the display release button is enabled, it is used if the number of displayed contents is 0. May misunderstand that the folder does not contain any content. By displaying the error, it is possible to make the user recognize that the number of contents to be displayed is 0 because the operation by the display cancel button is effective.

  In the content display device of the present invention described above, the list display means displays the list so as to be distinguished from the display contents that display the display contents that are not displayed as a list by the display release means.

  In this way, after the display cancel button is operated, when the folder in which the display content is stored is changed and displayed in a list, the user can immediately know that the display cancel button is valid.

  In the content display device of the present invention described above, the list display means changes the color of the display contents that are not displayed as a list by the display cancellation means or displays the list by shading.

  In this way, it becomes easy to understand that the display content is not displayed as a list by the display cancellation unit.

  In the content display device of the present invention described above, the display cancellation unit is configured not to display the list when a predetermined operation is performed for the first time after the folder designation unit changes the designation of the folder. The display content is switched between display and non-display.

  In this way, after the folder is changed, if a predetermined operation such as clicking a screen displayed in a list is performed, the display content that is not displayed in the list is switched between display and non-display. Does not confuse whether the cancel button is enabled or disabled.

  Further, the content display method corresponding to the content display device of the present invention described above includes a content acquisition step of acquiring a plurality of display contents that are contents to be displayed as a list, and a list display step of displaying the list of the plurality of display contents as a list. , A classification step for classifying the display content, a button display step for displaying a display release button associated with the classification, and when the display release button is operated, the classification of the classification corresponding to the display release button A display cancellation step of canceling display so that the display content is not displayed in a list by the list display step, and the display cancellation step is displayed as a result even when the display cancellation button is operated. The gist is not to cancel the display when there is no display content.

  The content display program corresponding to the content display device of the present invention described above includes a content acquisition function for acquiring a plurality of display contents that are contents to be displayed in a list, and a list display function for displaying a list of the plurality of display contents. A classification function for classifying the display content; a button display function for displaying a display cancellation button associated with the classification; and when the display cancellation button is operated, the classification of the classification corresponding to the display cancellation button A display cancellation function for canceling display so that the display content is not displayed in a list by the list display function. The display cancellation function displays the result even if the display cancellation button is operated. If there is no display content to be displayed, the gist is not to cancel the display. That.

  According to the content display method and the content display program described above, the same effects as the content display device of the present invention can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an explanatory diagram illustrating a schematic configuration of a content display apparatus 100 that stores a plurality of image files and displays a list of the plurality of image files.

  The content display apparatus 100 includes a folder designation unit 125, a classification unit 122, a classification storage unit 123, a button display unit 127 that displays a plurality of display release buttons 130, a content acquisition unit 105, a display release unit 120, a list display unit 110, a mark An adding unit 115 and a mark deleting unit 116 are included.

  The folder designation unit 125 designates a folder in which images to be displayed in a list are stored.

  The classifying unit 122 classifies the images according to the mark state. In the first embodiment, the state of the mark is represented by the type of mark added to the image and the fact that no mark is added.

  The classification storage unit 123 stores the state of the mark of the image to be displayed as a list for each folder.

  The button display unit 127 displays the display release button 130 associated with the mark state. In the first embodiment, since the state of the mark is represented by the type of mark added to the image and the mark not added, the button display means 127 has (number of mark types + 1) display release buttons 130. Is displayed.

  The content acquisition unit 105 acquires an image that matches the mark state stored in the classification storage unit 123 among the images in the folder specified by the folder specification unit.

  The display cancellation unit 120 does not display a list of images that are not displayed as a list, that is, a mark that is not displayed as a list. Further, the display cancellation unit 120 sets the classification of the images not displayed as a list to the state of the mark stored in the classification storage unit 123 or the state of the mark associated with the display cancellation button 130.

  The list display unit 110 displays a list of images obtained by removing images that the display cancellation unit 120 does not display in a list from the images acquired by the content acquisition unit 120.

  The mark adding means 115 adds a mark to the image. The mark deletion unit 116 deletes the mark from the image.

  The hard disk 140 stores a plurality of image files such as images taken with a digital still camera. In addition, a mark to be added or deleted by the mark adding unit 115 or the mark deleting unit 116 may be added to the plurality of image files in advance as necessary. As the mark, a mark of a preset type is used for identifying an image file for various purposes.

  The content display device 100 configured as described above is configured by a computer that implements the processing of each unit by a software program and installs the content display program that is the processing program. This computer (not shown) includes a CPU, ROM, RAM, hard disk 140, interface, and the like, and is a general computer connected to a keyboard, a display, and the like. A content display program is stored in the ROM of this computer, and functions as the content display device 100 when the CPU executes the content display program.

  FIG. 2 is an explanatory diagram for explaining a screen displayed on the display of the computer by the content display device 100. This screen is a folder list screen 200 that displays a list of folders, an image list screen 210 that displays a list of images in the folder specified on the folder list screen 200 as thumbnail images 220, and an image that is displayed on the image list screen 210. It consists of a narrowing condition setting screen 230.

  On the folder list screen 200, a list of folders on the hard disk 140 is displayed with an indent so that the hierarchy can be understood. When the user of the content display apparatus 100 selects one folder in the folder list and clicks it with the mouse, the folder designation unit 125 designates the folder clicked with the mouse as the designated folder 205 for displaying a list. In addition, the designated folder 205 clicked with the mouse is displayed with a frame and is distinguished from other folders.

  On the image list screen 210, a list of thumbnail images 220 obtained by reducing the images stored in the designated folder 205 is displayed. Each thumbnail image 220 displays a file name below and a mark added above.

  The condition setting screen 230 narrows down the conditions of the display cancel button group 235 for selecting a mark added to an image that should not be displayed among the thumbnail images 220 displayed on the image list screen 210 and the thumbnail image 220 to be displayed in a list. The search button 240, the display cancel button group 235, and the display setting save button 245 for saving the setting by the search button 240 as the display setting of the designated folder 205 are displayed.

  The five buttons in the display release button group 235 are associated with five types of mark states in total from the left, that is, the mark type (four types) and the unmarked state.

  The five buttons of the display cancel button group 235 are assigned values “10000”, “01000”, “00100”, “00010”, and “00001” in binary numbers from the left, and are displayed as display cancel marks. The display cancellation mark is indicated by a logical sum of values assigned to the pressed button in the display cancellation button group 235. For example, when the ○ and □ buttons in the display release button group 235 are pressed, the display release mark is “01010”.

  In addition, the display cancel button group 235 according to the first embodiment represents marks of images that are not displayed as a list, but may conversely represent marks of images that are displayed as a list. In this case, a display button group including the same number of buttons as the display release button group 235 is provided, and a display mark indicating a pressed button in the display button group is used. Similar to the display release mark, the display mark represents a pressed button in the display button group in binary.

  For example, when the display mark is “01010”, that is, when the buttons ◯ and □ are pressed, the images with the marks ◯ and □ are displayed as a list of images that are suitable for the display mark. When the display mark is “00001”, that is, when the “none” button is pressed, only an image without the mark is an image that matches the display mark.

  In the following, the processing of each unit executed by the CPU in this computer will be described with reference to the flowcharts of FIG. 3, FIG. 5, and FIG.

  When the process starts, in step S100 in FIG. 3, the CPU acquires an image file from the designated folder 205 and creates a display list.

  FIG. 4 is an explanatory diagram for explaining the structure of the display list. The display list includes the image file name, image data, display flag, display release flag, search flag, added mark, and other information obtained from the metadata added to the image file from the left. Each table is recorded in tabular form. The display flag, display release flag, and search flag are set to 1 when set, and set to 0 when reset. The mark is represented by setting the column corresponding to the mark added to each image to 1. In the display list of FIG. 4, the display flag, the display release flag, the search flag, and the column in which the added mark is 0 are represented by blanks.

  In step S100, the CPU writes data to the file name, image data, added mark, and other information in the display list, and sets all search flags. The display flag and the display release flag are reset to 0.

  A display flag, a display release flag, and a search flag indicate whether the image is a list display image. The list display means 110 displays a list of images for which the display flag and the search flag are set and the display release flag is 0.

  In addition, when the designated folder 205 is not designated by the folder designation unit 125, a predetermined folder becomes the designated folder 205.

  In step S105, the CPU acquires the display classification and extraction conditions of the designated folder 205. The display classification is a state of marks to be displayed as a list, which is saved for each folder by the display setting save button 245. The extraction condition is a condition of images displayed as a list when the display setting save button 245 is pressed, and includes the display classification and the search condition set by the search button 240.

  In step S110, the CPU sets a display flag from an image in the display list to an image that matches the display classification. FIG. 4 shows an example in which the states of four marks, ie, a round mark, a triangular mark, a square mark, and no mark are stored as display classifications. Therefore, an image having a round mark, a triangular mark, and a square mark, and an image with no mark added, such as an image. jpeg, Imgbb. Display flags are set for 13 images excluding jpeg.

  Next, in step 115, the CPU checks whether the number of images in which a display flag that is a displayable image is set is zero. If the number of images for which the display flag is set is 0, the process proceeds to step S120. On the other hand, if the number of images for which the display flag is set is not 0, the process proceeds to step S125.

  In step S120, the CPU sets a display flag for all images in the display list.

  At this time, an error message may be issued. By doing this, it is possible to make the user recognize that there is no image to be displayed because the designated folder 205 has been changed.

  In step S125, the CPU resets a search flag for an image that satisfies the extraction condition among the images in the display list. By doing so, the images that were previously displayed in the list when the display setting button 245 was pressed in the same folder are not displayed again, so that the same image is not viewed many times.

  In step S130, the CPU checks whether or not the number of images that can be displayed, that is, the number of images in which the display flag is 1, the display release flag is 0, and the search flag is 1 is 0. If the number of images that can be displayed is zero, the process proceeds to step S135. On the other hand, if the number of images that can be displayed is not zero, the process proceeds to step S140.

  In step S135, the CPU sets search flags for all images, and returns to a state where no extraction condition is used.

  In step S140, the CPU sets a display cancellation flag for an image that matches the display cancellation mark.

  An image suitable for the display release mark is an image to which a mark associated with the display release button indicated by the display release mark is added. For example, when the display release mark is “01010”, that is, when the buttons ◯ and □ are pressed, an image to which the mark ◯ or □ is added becomes an image suitable for the display release mark. When the display release mark is “00001”, that is, when the “None” button is pressed, an image without the mark is an image suitable for the display release mark. In FIG. 4, the display cancellation mark is “01000”, the circle mark is designated, and the Imgcc. In this example, the display cancellation flag is set in jpeg.

  In step S145, the CPU checks whether or not the number of images that can be displayed, that is, the number of images in which the display flag is 1, the display release flag is 0, and the search flag is 1 is 0. If the number of images that can be displayed is zero, the process proceeds to step S150. On the other hand, if the number of images that can be displayed is not zero, the process proceeds to step S200 (FIG. 5).

  In step S150, the display release flags of all images are reset.

  At this time, an error message may be issued. By doing this, it is possible to make the user recognize that there is no image to be displayed because the designated folder 205 has been changed.

  In step S200 (FIG. 5), the CPU displays a list of the thumbnail images 220 of the images in the display list in which the display flag and the search flag are set and the display release flag is not set together with the added mark. To do. A folder list and buttons are also displayed.

  In step S210, the CPU checks whether any button of display cancel button group 235 has been operated. If any button in the display cancel button group 235 is operated, the process proceeds to step S212, and the display cancel mark is updated. On the other hand, if any button in the display cancel button group 235 is not operated, the process proceeds to step S235.

  FIG. 6 is a flowchart for explaining the display cancellation mark update processing. When the display release mark update process starts, it is checked in step S300 whether the button has been pressed or released. The buttons are operated with a mouse or the like. If the button is not pressed, clicking the button with the mouse determines that the button has been pressed. On the other hand, when the button is already pressed, if the button is clicked with the mouse, it is determined that the button is released. If the button has been pressed, the process proceeds to step S310. On the other hand, if the button is released, the process proceeds to step S350.

  In step S310, the CPU calculates the number of images that are not in the mark state corresponding to the pressed display release button among the images currently displayed in a list.

  In step S320, the CPU checks whether the calculated number of images is zero. If the calculated number of images is 0, the process proceeds to step S340. On the other hand, if the calculated number of images is not 0, the process proceeds to step S330.

  In step S330, the CPU adds a mark corresponding to the pressed display release button to the display release mark, and ends the display release mark update process. For example, if a display cancel button associated with no mark is pressed, no mark is added to the display cancel mark.

  In step S340, the CPU returns the pressed display release button to the non-pressed state, and ends the display release mark update process. In this way, when the number of images that can be displayed is zero, an image in the state of the mark associated with the display release button that was pressed last in the display release button group 235 that was pressed is displayed. Can be displayed.

  In step S350, the CPU deletes the mark state corresponding to the released display release button from the display release mark, and ends the display release mark update process.

  In step S235, the CPU checks whether the thumbnail image 220 on the image list screen 210 has been clicked. If the thumbnail image 220 on the image list screen 210 is clicked, the process proceeds to step S240. On the other hand, if the thumbnail image 220 on the image list screen 210 has not been clicked, the process proceeds to step S245.

  In step S240, the CPU displays a menu and adds or deletes a mark. FIG. 7 shows a menu displayed at this time. This menu has marks from the top. When a mark not added to the image is selected from this menu, the mark is added to the image. Conversely, when a mark already added to the image is selected, the mark is deleted from the image. Then, the result of this operation is reflected in the mark column of the display list.

  In step S245, the CPU checks whether search button 240 has been pressed. If the search button 240 is pressed, the process proceeds to step S250. On the other hand, if the search button 240 has not been pressed, the process proceeds to step S255.

  In step S250, the CPU displays a dialog box in which an image can be searched using items in metadata previously added to the image file, such as the creation date and time, and the image file name. A search condition for searching for metadata is acquired, a search is executed under this search condition, a search flag for an image as a search result is set, and a search flag for an image that has not been searched is reset. If the number of search result images is 0, the search flag is restored. Note that search of an image file with metadata such as creation date and time, image file name, and the like has been performed well so far, and details thereof will not be described.

  Next, in step S255, the CPU checks whether the display setting save button 245 has been pressed. If the display setting save button 245 is pressed, the process proceeds to step S260. On the other hand, if the display setting save button 245 has not been pressed, the process proceeds to step S265.

  In step S260, the CPU stores display classification and extraction conditions for each folder. The display classification is a mark state that does not conform to the display release mark. For example, when the mark “01000” is designated as the display release mark, the display classification is “10111”. The extraction conditions are display classification and search conditions stored in step S250, and indicate the conditions of the images currently displayed in a list. In this way, the mark state and search conditions of the images displayed as a list when the display setting save button 245 is pressed can be saved for each folder.

  In step S265, the CPU checks whether the folder is clicked on folder list screen 200 and the designation of the folder is changed. If the folder is clicked on the folder list screen 200 and the folder designation is changed, the process proceeds to step S270. On the other hand, if the folder is clicked on the folder list screen 200 and the designation of the folder has not been changed, the process proceeds to step S275.

  In step S270, the CPU changes the designated folder 205 to the designated folder 205 as the clicked folder. Then, the process returns to step S100 to display a list of images in the changed folder.

  Next, in step S275, the CPU sets a display cancel flag for an image that matches the display cancel mark, resets a display cancel flag for an image that does not match the display cancel mark, returns to step S200, and releases a new display cancel. Display a list with marks and search conditions.

  In this way, the images to be displayed in a list can be narrowed down simply by operating the display cancel button group 235. Therefore, since the number of thumbnail images 220 displayed in a list can be reduced, the user can easily find a desired image. Further, as a result of operating the display cancel button group 235 in step S320 (FIG. 6), it is determined whether or not the number of thumbnail images 220 displayed as a list is zero, and if so, step S340 ( In FIG. 6), the operation of the display cancel button group 235 is invalidated. Therefore, even if the thumbnail images 220 to be displayed in a list are narrowed down by operating the display cancel button group 235, it is possible to prevent that none of the thumbnail images 220 displayed in the list are displayed, resulting in confusion for the user. I won't let you.

  In addition, since the end of the processing of the content display device varies depending on the purpose of use of the content display device and the processing to be combined, the flowchart for explaining the processing of the content display device described with reference to FIGS. Processing termination conditions are not described. For example, when the content processing apparatus is used in combination with an image printing apparatus (not shown) that selects an image and prints the selected image, the following two image printing apparatus processes are performed in steps S265 and S275. Inserted between.

(1) A process for allowing a user to select an image from images displayed in a list by the content display device.
(2) Processing for acquiring an instruction to end selection of an image by the user and executing printing processing of the selected image.

  In this way, an image is selected from the images that are narrowed down by the content display device and displayed as a list by the processing (1) of the image printing device, and an instruction to end the selection of the image by the processing (2) of the image printing device. Is acquired, the processing of the content display device ends.

  Further, since the folder storing the images to be displayed in a list can be specified on the folder list screen 200, the thumbnail images 220 to be displayed in a list can be narrowed down.

  Further, since the folder storing the images to be displayed in a list can be specified on the folder list screen 200, the thumbnail images 220 to be displayed in a list can be narrowed down.

  When the designated folder 205 is changed, it is checked in step S115 and step S135 whether or not the number of images to be displayed is 0. If it is 0, the display classification and extraction conditions are not used. . for that reason. By changing the folder, it can be prevented that no image is displayed, and the possibility of causing confusion to the user can be reduced.

Hereinafter, modified examples related to the content display device 100 according to the first embodiment will be described.
(Modification 1)
In step S200 (FIG. 5), shading is displayed on an image that is not displayed as a list. In this way, the user can immediately recognize that the image is not displayed by the display cancel button group 235, and the user will not be confused.

(Modification 2)
In the case of the list display immediately after the folder is changed in step S200 (FIG. 5), the operation of the user is awaited after displaying the list of images. Then, when operated by the user, the display release mark is invalidated and the process is repeated from step S100. In this way, when the folder is changed, the display release mark specified in the previous folder is valid, and the image corresponding to the display release mark is not displayed. The specified display release mark becomes invalid and all images are displayed. Therefore, the user can easily understand that the designation of the display release mark designated in the previous folder becomes invalid in the changed folder.

  In step S200 (FIG. 5), in the list display immediately after the folder is changed, the display release mark is invalidated and all images are displayed, and a user operation is waited for. Then, when operated by the user, the display release mark may be validated and the process may be repeated from step S100. In this way, when the folder is changed, the display release mark specified in the previous folder is invalid, and the image corresponding to the display release mark is also displayed. The designated display release mark becomes valid, and only the image corresponding to the display release mark is displayed. Therefore, the user can easily understand that the designation of the display release mark designated in the previous folder is effective even in the changed folder.
