JP4419060B2 - Information processing apparatus and method, and program - Google Patents

Description

  The present invention relates to an information processing apparatus and method, and a program, and more particularly, to an information processing apparatus and method, and a program that make it possible to easily find target content.

  As can be seen with the Explorer function of Windows (registered trademark), which is popular as an operating system (OS) for personal computers, most content data (hereinafter simply referred to as content) has its creation date as its attribute information. Etc. date information is added.

  Therefore, for example, the user can search for the target content by using the creation date as a key by using an explorer function such as sorting the content stored in a certain folder in the order of creation date.

  By the way, depending on the type of content, even when rearranged in order of creation date, there is a content that cannot easily find the target content from the rearranged result.

  For example, in the case of content created by the user, such as content of materials required for a meeting held on a certain day, if it is prepared the day before the meeting date, a date different from the meeting date is set as the creation date. The In addition, when a correction is made to a typo or the like after the date of the meeting, the correction date is set as the creation date.

  Therefore, since the creation date added as attribute information is set to a date different from the conference date to be used as a key when searching for content, the content is searched for using the conference date as a key before and after the conference. If you are trying to do it, you may not be able to do what you think.

  In the case of content such as a still image that does not change the creation date (shooting date) once set unless editing is performed, the content can be searched for using the creation date as a key. However, in the case of content created by the user, this may be difficult.

  Therefore, in order to eliminate such a poor operability, a technology has been proposed in which content is associated with a conference day as described above so that the required content can be reliably found from the conference date. (For example, Patent Document 1).

  Patent Document 1 describes a technique in which image data is stored in association with a schedule input by a user, and an image associated with that date is displayed when a predetermined date is reached.

Patent Document 2 describes a technique for classifying stored photographed images for each predetermined photographing period and displaying a list of classified images.

  FIG. 6 is a diagram illustrating an example of a main screen displayed on the LCD 28.

  Various operations performed using the PDA 1 are basically started from this main screen. The main screen includes a standard display area 201, a silk area 202, and a status area 203.

  In the standard display area 201, when an application program (software) is being executed, a screen of the application program being executed is displayed. When the application program is not executed, application icons 204 corresponding to each of the installed application programs are displayed as shown in FIG. 6 (however, strictly speaking, the application icon 204 is also displayed at this time. The program is not executed at all, and an application program for displaying the application icon 204 and allowing the user to select is executed).

  In FIG. 6, as an application icon 204, a notepad icon 204 </ b> A that is tapped when the application for creating a memo is executed (the surface of the LCD 28 is pressed at the tip of the stylus 2). A schedule icon 204B to be tapped is displayed.

  In the silk area 202, a user interface (area for user input) corresponding to the silk plug-in being executed is displayed. Depending on the application to be executed, the display of the silk area 202 may disappear, and one screen may be displayed on the entire standard display area 201 and the silk area 202.

  In the status area 203, for example, a status icon 205 indicating the state of the PDA 1 such as the battery capacity, the presence / absence of the MS3 in the MS slot 41, the presence / absence of the CF4 in the CF slot 42, and the volume setting are displayed. Is done.

  FIG. 7 is a diagram showing an example of a screen displayed when the memo pad icon 204A in FIG. 6 is tapped.

  The memo creation screen shown in FIG. 7 is displayed by software (database processing software described later) that manages the creation of memos, which is activated when the memo pad icon 204A is tapped.

  In addition to the status area 203, the memo creation screen includes a memo creation area 211 and a tool button area 212 in which various buttons operated when selecting a tool for creating a memo are displayed.

  The user can input arbitrary characters, symbols, and the like to the memo creation area 211 by moving the stylus 2 while keeping the tip of the stylus 2 against the memo creation area 211. For example, the curved image 231 in FIG. 8 represents a trajectory of the movement of the tip of the stylus 2, and thus the user can take a memo in the memo creation area 211 using the stylus 2.

  Further, as will be described in detail later, the user not only inputs characters and symbols with the stylus 2 but also displays images representing various contents such as still images and moving images taken with the camera unit 21 or recorded audio. You can also create a note by pasting it (you can associate content with the note).

  In the tool button area 212 of FIG. 7, a list display button 221 that is operated (tapped) when displaying a list of contents to be pasted on a memo or closing a list of contents already displayed, a memo creation area 211 A pen button 222 to be operated when inputting handwritten characters or the like is prepared. When the pen button 222 is operated by the user, the pen mode is set. While the pen mode is set, handwritten input as shown in FIG. 8 can be performed on the memo creation area 211.

  The tool button area 212 also displays buttons operated when selecting various tools, in addition to an eraser button 223 operated when erasing characters once entered in the memo creating area 211.

  FIG. 9 is a diagram illustrating an example of a screen displayed when the list display button 221 is tapped in the state of FIG. 8 (a state where the content list is not displayed).

  When the list display button 221 is tapped, as shown in FIG. 9, it is an area including an area between the tool button area 212 and the status area 203 that has previously formed a part of the memo creation area 211. A thumbnail display area 241 is formed, and a list of contents (thumbnail images representing the contents) that can be pasted on a memo created using the memo creation area 211 is displayed.

  The thumbnail image displayed in the thumbnail display area 241 is generated from the data of the content body. For example, the thumbnail image of the still image content is generated by reducing the still image of the content body, and the thumbnail image of the moving image content is selected from continuous images. For example, the first frame (MPEG ( In the case of moving image content compressed by the Moving Picture Experts Group) method, the image is generated by reducing the first I (Intra) picture. Note that a balloon image is used as the thumbnail image of the audio content.

  In the example of FIG. 9, from the left, a thumbnail image 251 representing a moving image content set with a file name “MOV000...”, A thumbnail image 252 representing an audio content set with a file name “031030. A thumbnail image 253 representing a still image (landscape image) content set with a file name “” and a thumbnail image 254 representing a still image (person image) content set with a file name “DSC0002” are displayed.

  The contents represented by these thumbnail images are stored in the storage unit 139 which is the internal memory of the PDA 1 or in the MS 3 mounted on the PDA 1.

For example, as indicated by the dotted arrow in FIG. 9, the stylus 2 is pressed against the thumbnail image 253 of the third still image content from the left and moved to the position P ₁ on the memo creation area 211 in that state, where it is moved. By moving the tip of the stylus 2 away from the surface of the LCD 28 (by dragging and dropping), the user can paste the thumbnail image 253 at the position P ₁ .

FIG. 10 is a diagram illustrating an example of a screen in a state where the thumbnail image 253 is pasted at the position P ₁ . In this way, the user can paste thumbnail images of various categories of contents such as still images into the memo being created by dragging and dropping from the list displayed. Note that the user can further move the thumbnail image 253 pasted at the position P ₁ to another position on the memo creation area 211 in a state where the pen mode is set.

  For example, the user inputs handwritten characters such as “photo taken when” in the memo creation area 211 and pastes a thumbnail image of a photo (still image content) in the memo. Photos in the PDA 1 can be easily classified. This operation is more intuitive than creating a new folder and storing it by storing content such as photos, and it is a PDA1 that can be easily operated in a short time while away from home. From the nature of

  Further, the user can start playback of the content represented by the thumbnail image by tapping the thumbnail image pasted on the memo.

  FIG. 11 is a diagram illustrating an example of a screen when the thumbnail image 253 in FIG. 10 is tapped to reproduce (preview) the still image content represented by the thumbnail image 253.

  When the thumbnail image 253 is tapped, software having a still image content viewer function (content processing software to be described later) is activated, and based on the data of the still image content main body represented by the thumbnail image 253 The image is displayed using the entire area other than the status area 203. Thereby, the user can easily confirm the details of the still image content.

  Note that when the thumbnail image 251 of the moving image content pasted on the memo is tapped, the moving image content is similarly reproduced, and the image is displayed using an area other than the status area 203 as shown in FIG. . When the thumbnail image 252 of the audio content pasted on the memo is tapped, the audio content is played back.

  12A to 12D are diagrams showing the hierarchical structure of the display of memos created as described above.

  FIG. 12A is a diagram showing a screen displayed in the memo creation area 211 of FIG. 10 (a portion excluding the numbers and characters (“Unfiled”) displayed above).

  The screen of FIG. 12A is composed of a plurality of layers, and nothing is input to the bottom layer of the plurality of layers as shown in FIG. 12B (a blank layer as in the memo creation area 211 of FIG. 7). Not layer) is placed.

  A layer for displaying the image 231 of the handwritten curve input by the stylus 2 is arranged on the plain layer in FIG. 12B, and a thumbnail image 253 is disposed on the layer (the uppermost layer constituting the screen in FIG. 12A). Is displayed. When a plurality of thumbnail images are pasted on a memo, the layers for displaying the thumbnail images are virtually arranged in the number pasted.

  As described above, the screen displayed in the memo creation area 211 by the software for managing the creation of the memo is composed of three layers shown in FIGS. 12B to 12D. The number of layers is different from the number of layers constituting a screen displayed in an area corresponding to the memo creation area 211 by software for managing creation of a schedule, which will be described later.

  Here, details of the display of the thumbnail display area 241 will be described.

  FIG. 13A is a diagram showing only the thumbnail display area 241 of FIG.

  On the upper right of the thumbnail display area 241, category selection buttons 261 to 264 for filtering the thumbnail image displayed on the thumbnail image display unit 271 according to the category of the content represented by the thumbnail image are displayed.

  That is, when the list display button 221 is operated, thumbnail images of all categories of content that can be pasted on a memo being created in the memo creation area 211 are displayed on the thumbnail image display unit 271. By operating the category selection buttons 261 to 264, the thumbnail images displayed on the thumbnail image display unit 271 can be limited.

  For example, when the category selection button 261 with a camera picture is operated, the thumbnail image of the still image content is removed from the thumbnail images displayed on the thumbnail image display unit 271 (the display disappears), and the film is displayed. When the category selection button 262 with the picture is operated, the thumbnail image of the moving image content is removed.

  Also, when the category selection button 263 with a pen and paper picture (memo) is operated, the thumbnail image representing the content of the memo is removed from the thumbnail images displayed on the thumbnail image display unit 271.

  In PDA1, during the creation of a memo (while the software that manages the creation of the memo is being executed), other pre-created memos cannot be pasted as content in the memo being created. It is said that. Therefore, while the memo is being created, the thumbnail image of the memo is not displayed on the thumbnail image display unit 271, so that the category selection button 263 cannot be operated.

  When software for managing the creation of a schedule to be described later is being executed, it is possible to paste a previously created memo as content in the schedule being created and the category selection button 263 is operated Then, the thumbnail image of the memo is removed from the thumbnail images displayed on the thumbnail image display unit 271.

  On the right side of the category selection button 263, a category selection button 264 with a balloon picture is prepared. When the category selection button 264 is operated, the thumbnail image of the audio content is removed from the thumbnail images displayed on the thumbnail image display unit 271.

  FIG. 13B shows a category selection button 262 (button for deleting the display of thumbnail images of moving image contents) and a category selection button from the state of FIG. 13A in which thumbnail images of content categories of still images, moving images, and audio are displayed. FIG. 26 is a diagram illustrating a display in a state where H.264 (a button for deleting the display of a thumbnail image of audio content) is operated.

  As shown in FIG. 13B, among the thumbnail images displayed on the thumbnail image display unit 271, thumbnail images representing moving image and audio content are cut by filtering, and the display is erased.

  In this way, the thumbnail image displayed on the thumbnail image display unit 271 can be filtered based on the category, so that the user can quickly find the thumbnail image of the content to be pasted.

  For example, when a certain still image content is to be pasted on a memo, the user can search for a still image content to be pasted by searching after removing thumbnail images of content in other categories as shown in FIG. 13B. Can quickly find thumbnail images.

  In the same manner as described above, the content represented by the thumbnail image can be reproduced from the thumbnail image displayed on the thumbnail image display unit 271 from the thumbnail image pasted on the memo. Can be started.

  For example, as shown in FIG. 13A, when the thumbnail image 253 of the still image content is further tapped with the cursor 281 selected, the still image content is displayed on the LCD 28 as described with reference to FIG. Is displayed enlarged. That is, software that provides a viewer function is executed, and still image content is displayed.

  A scroll bar 272 that is operated in the horizontal direction when switching the range of thumbnail images to be displayed on the thumbnail image display unit 271 is displayed below the thumbnail image display unit 271, and below that is selected by the cursor 281. A content information display unit 273 that displays the name of the content that is being displayed is displayed.

  In FIG. 13A, an image 251A representing the appearance of the MS3 displayed on the thumbnail image 251 of the moving image content indicates that the moving image content is stored in the external memory MS3. . Further, an image 251B representing a picture of a film represents that the thumbnail image 251 to which the image is attached is of a moving image content (can be distinguished from a thumbnail image of still image content).

  FIG. 14 is a diagram illustrating an example of a screen displayed when the schedule icon 204B in FIG. 6 is tapped. 14, the same parts as those in FIG. 7 are denoted by the same reference numerals.

  When the schedule icon 204B is tapped, software for managing the creation of the schedule is activated, and a schedule creation screen as shown in FIG. 14 is displayed.

  In addition to the status area 203, the schedule creation screen displays the schedule input area 301 in which time is displayed at predetermined intervals, and the display format of the schedule input area 301 (display format in units of weeks and months). A display switching area 302 where buttons to be operated and the like are prepared, and a tool button area 303 where buttons to be operated when selecting a tool for creating a schedule are prepared.

  The tool button area 303 is operated when a list display button 221 operated when displaying a list of thumbnail images of contents to be pasted on the schedule, and is operated when handwritten characters or symbols are input in the schedule input area 301. The same buttons as those prepared in the tool button area 212 of FIG. 7 such as the pen button 222 and the eraser button 223 operated when erasing a handwritten character once inputted are prepared.

  In addition to these buttons, the tool button area 303 selects one item scheduled in the schedule input area 301 and moves the selected item or selects a hand mode for changing the contents. A hand button 311 to be operated is displayed. This hand button 311 is a button that is not prepared when creating the memo described above.

  FIG. 15 is a diagram illustrating an example of a screen in a state where a certain schedule is input with respect to the screen of FIG.

  For the schedule 321 (schedule in which “conference” is input) entered in the 9 o'clock (9:00) field of the schedule input area 301, for example, the hand button 311 is operated by the user, and the hand mode is set. It is input after being done. When the 9 o'clock time zone is selected by the stylus 2 as a time zone for inputting the schedule, the silk area 202 of FIG. 6 is displayed at the bottom of the screen, and the user inputs the schedule using that area. Yes (enter “Meeting”).

  The button to the right of the list display button 221 is a button that is operated when creating a new schedule. Even when this button is operated, the time zone is specified with the hand mode set. It is possible to input a new schedule in the same manner as when the new schedule is made.

  FIG. 16 is a diagram illustrating a screen in a state where an image 331 including a handwritten character “important!” And an arrow image pointing to the schedule 321 is input to the screen in the state in FIG. 15.

  By operating the pen button 222 and setting the pen mode, the user can input handwritten characters or the like in the schedule input area 301.

  In this way, even when creating a schedule, the user can input handwritten characters in the same manner as when creating a memo, as well as inputting scheduled items during a predetermined time period.

  FIG. 17 is a diagram illustrating an example of a screen displayed when the list display button 221 is tapped in the state of FIG. 16 (a state where the list of thumbnail images is not displayed).

  When the list display button 221 is tapped, as shown in FIG. 17, it is an area including an area between the tool button area 303 and the status area 203 that previously formed a part of the scheduled input area 301. A thumbnail display area 241 is formed, and a list of thumbnail images of contents that can be pasted in the schedule input area 301 is displayed there.

For example, the thumbnail image 352 of the audio content is selected with the stylus 2 and moved to the position P ₂ on the planned input area 301 as shown by the dotted arrow in FIG. by releasing from the surface, the user can paste a thumbnail image 352 to the position P _2.

Figure 18 is a diagram showing an example of a screen in a state where the thumbnail image 352 is pasted audio content to the position P _2.

  Thus, the user can paste thumbnail images of various categories of content on the schedule by dragging and dropping from the list displayed (contents can be associated with the schedule). .

  Since the thumbnail image can be pasted on the schedule as described above, for example, when the meeting from 9 o'clock (“meeting” of the schedule 321 in FIG. 18) ends, the user records it at that time. By pasting the thumbnail image 351 of the audio content that has been placed around the schedule 321, it is possible to easily find the audio content recorded at the meeting later.

  The pasting of the thumbnail image is also a very intuitive operation by simply dragging and dropping from those displayed in the thumbnail display area 241.

  Further, by tapping the thumbnail image 351 pasted on the schedule, it is possible to start playback of the audio content represented by the thumbnail image 351, so that the user can easily record the audio recorded at the conference from the schedule. Can be played.

  In FIGS. 17 and 18, thumbnail images 353 and 354 are memo thumbnail images created in advance. As described above, when a schedule is created, a memo created in advance can be associated as a content with the schedule, so that a thumbnail image of the memo is also displayed in the thumbnail display area 241.

  19A to 19E are diagrams showing the hierarchical structure of the schedule table created as described above.

  FIG. 19A shows a screen displayed in the scheduled input area 301 of FIG. 18 (the part excluding the year, month, day, and day of the week (S, M, T, W, T, F, S) displayed at the top of FIG. 18). FIG.

  The screen in FIG. 19A is also composed of a plurality of layers, and in the lowermost layer, a layer for displaying a time zone as shown in FIG. 19B (any schedule is input as in the schedule input area 301 in FIG. 14). Not the calendar layer).

  On the layer in FIG. 19B, as shown in FIG. 19C, a layer for displaying the schedule 321 input by the user (schedule input in the 9 o'clock time zone in FIG. 19B) is arranged. As shown in FIG. 19D, a layer for displaying the handwritten “important!” Character input by the stylus 2 and an arrow image 331 indicating the schedule 321 is arranged.

  As shown in FIG. 19E, a layer for displaying the thumbnail image 352 is arranged at the top layer of the screen in FIG. 19A.

  As described above, the screen displayed in the schedule input area 301 by the software for managing the creation of the schedule is composed of four layers shown in FIGS. 19B to 19E. The number of layers (four layers) is different from the number of layers (three layers) constituting the screen displayed by the software for managing creation of a memo described above.

  That is, the paste destination of the thumbnail image displayed in the thumbnail display area 241 differs depending on the category of data created using the screen displayed simultaneously with the list of thumbnail images, and can be said to be plural.

  Next, a software configuration for realizing the above screen display will be described.

  In the following, one memo file created by software for managing creation of a memo and one schedule file created by software for managing creation of a schedule are also referred to as a database. Therefore, the content paste destination and handwritten character input destination are the database.

  FIG. 20 is a block diagram illustrating an example of software prepared in the PDA 1.

  These software are stored in a storage unit 139 (FIG. 5) which is a built-in memory. The PDA 1 is provided with a database processing software group 361 composed of a plurality of database processing softwares, a content processing software group 362 composed of a plurality of content processing softwares, and a thumbnail display software 363.

  The database processing software group 361 includes memo database processing software 371-1 for managing creation of a memo database and schedule table database processing software 371-2 for managing creation of a schedule database. Hereinafter, when it is not necessary to individually distinguish the memo database processing software 371-1 and the schedule table database processing software 371-2, they are collectively referred to as the database processing software 371.

  In FIG. 20, only two pieces of database processing software are prepared. However, in actuality, the application icon 204 is prepared on the screen of FIG. Database processing software is prepared for each.

  The database processing software 371 provides a database creation function to the user, and accepts input of handwritten characters by the stylus 2 and pasting of thumbnail images, for example, and creates a database.

  The database processing software 371 manages the creation of each database using database configuration information representing the configuration of the database as shown in FIG.

  In the example of FIG. 21, the type of content or the like represented by the thumbnail image pasted in the database, the link destination of the thumbnail image (the storage location of the content main body data), and the position on the database where the thumbnail image is pasted Coordinates representing information and other information related to the contents are represented by database configuration information.

Each time a thumbnail image is pasted or a handwritten character is input, these pieces of information are registered in the database configuration information. In the example of FIG. 21, in the second stage of the database configuration information, the link destination of the handwritten character input to a certain database is the link information # 1, and the input position is the coordinates (x ₁ , y ₁ ). It is registered. In addition to the width W ₁ and the height h ₁ of the handwritten character, the color of the handwritten character, the thickness of the pen, and the like are registered as other information.

  Similarly, link information, position, width, height, and other information of thumbnail images of moving image content, still image content, text, and audio content pasted in the same database are also registered. The “text” shown as being input to the database in FIG. 21 is, for example, a schedule input to the schedule database. The “coordinates” registered in the database configuration information is, for example, the coordinates of the upper left corner of the thumbnail image.

  Returning to the description of FIG. 20, contents # 1 to # 3 are associated with the database 391 managed by the database processing software 371 (the thumbnail images of the contents # 1 to # 3 are pasted to the database 391). Is).

  That is, in this case, the database processing software 371 uses the database configuration information to determine the content type of the content # 1 to # 3 associated with the database 391, the link information of the thumbnail image, the pasting position, and other information. Is managing.

  When the thumbnail image pasted on the database 391 is tapped and the reproduction of the content is instructed, the database processing software 371 reproduces the content to one of the content processing software constituting the content processing software group 362. Request.

  In addition, when the list display button 221 is operated by the user and the display of a list of thumbnail images to be pasted to the database 391 being created is instructed, the database processing software 371 notifies the thumbnail display software 363 of that. , Display a list of thumbnail images.

  The content processing software group 362 includes still image content processing software 381-1 that manages reproduction (preview) of still image content, moving image content processing software 381-2 that manages reproduction of moving image content, and reproduction of audio content. Audio content processing software 381-3 to be managed and memo content processing software 381-4 to manage reproduction (preview) of a memo prepared as content. Hereinafter, when it is not necessary to individually distinguish the still image content processing software 381-1 to the memo content processing software 381-4, they are collectively referred to as content processing software 381.

  The content processing software 381 manages all the content 392 stored in the storage unit 139 and the MS 3 and provides a content viewer function. When the reproduction of the still image content is requested from the database processing software 371, the still image content is reproduced by the still image content processing software 381-1. When the reproduction of the moving image content is requested, the moving image content processing software The moving image content is reproduced by the wear 381-2. When the reproduction of the audio content is requested, the audio content is reproduced by the audio content processing software 381-3. When the reproduction of the memo is requested, the reproduction of the memo is performed by the memo content processing software 381-4. Is done.

  Note that the memo may be reproduced by the database processing software 371 (memo database processing software 371-1) that created the memo.

  As described above, the user can also play back the content by tapping the thumbnail images displayed in the thumbnail display area 241 as a list. When a thumbnail image displayed in the thumbnail display area 241 is tapped, the content is notified from the thumbnail display software 363, and the content is played back by the content processing software 381 in accordance with the content category instructed to be played back. Is done.

  When the thumbnail display software 363 requests display of a list of thumbnail images from the database processing software 371, the thumbnail display software 363 refers to the content 392, generates thumbnail images representing the respective contents, and displays the thumbnail images in the thumbnail display area 241. To display a list. When the thumbnail display software 363 is requested to limit the category of content to be displayed as a list of thumbnail images (when one of the category selection buttons 261 to 264 is operated), the thumbnail display software 363 responds to the request with the thumbnail. Update the image display.

  Furthermore, when the thumbnail image displayed in the thumbnail display area 241 is tapped, the thumbnail display software 363 requests the content processing software 381 to reproduce the content.

  FIG. 22 is a block diagram illustrating an example of a functional configuration of the PDA 1 realized by executing the software illustrated in FIG.

  The database configuration information management unit 401 realized by the database processing software 371 manages the database configuration information as shown in FIG. 21 based on the input from the user detected on the touch panel 36, and the database as necessary. The configuration information is provided to the database display control unit 402.

  In addition, when the thumbnail image pasted in the database is tapped and the reproduction of the content is instructed based on the output from the touch panel 36, the database configuration information management unit 401 detects this, based on the output from the touch panel 36. Notify

  The database display control unit 402 controls the display of the memo creation area 211 in FIG. 7 and the scheduled input area 301 in FIG. 14 according to the information provided from the database configuration information management unit 401.

  For example, when the database configuration information management unit 401 provides the database configuration information of FIG. 21, the database display control unit 402 represents handwritten characters (information registered in the second row) with other information. In addition to displaying the color and thickness at a position represented by coordinates (x1, y1), thumbnail images and the like are also displayed at a predetermined size on the database at a predetermined size for other contents. The information indicating the size of the thumbnail image is described as, for example, other information in FIG.

  When the thumbnail image of the still image content is tapped, the reproduction request unit 403 requests the still image content reproduction unit 421-1 realized by the still image content processing software 381-1 to reproduce the still image content, and When the thumbnail image of the content is tapped, the moving image content reproduction unit 421-2 realized by the moving image content processing software 381-2 is requested to reproduce the moving image content.

  Further, when the thumbnail image of the audio content is tapped, the reproduction request unit 403 requests the audio content reproduction unit 421-3 realized by the audio content processing software 381-3 to reproduce the audio content, and the thumbnail of the memo. When the image is tapped, the memo content playback unit 421-4 realized by the memo content processing software 381-4 is requested to play back the memo.

  When the display request unit 404 detects a user operation on the list display button 221 and is instructed to display a list of thumbnail images, the display request unit 404 requests the search unit 411 realized by the thumbnail display software 363, On the other hand, when it is instructed to close the list of thumbnail images, the thumbnail image display control unit 413 is requested to do so.

  The search unit 411 realized by the thumbnail display software 363 includes a still image content search unit 411-1 that searches for still image content, a moving image content search unit 411-2 that searches for moving image content, and a search for audio content. A music content search unit 411-3 and a memo content search unit 411-4 for searching for memos are included. As described above, the PDA 1 is provided with a function unit for searching for content for each category of content.

  Each of the still image content search unit 411-1 to the memo content search unit 411-4 searches for content in response to a request from the display request unit 404 of the database processing software 371 to display a list of thumbnail images. And the search result is output to the thumbnail image generation unit 412. The content search by the still image content search unit 411-1 to the memo content search unit 411-4 is performed on the MS3, CF4, and the storage unit 139 when the PDA 1 is equipped with the MS3 or CF4. When the MS 3 or the CF 4 is not attached, only the storage unit 139 is performed.

  The thumbnail image generation unit 412 generates a thumbnail image of each content based on the search result supplied from the search unit 411 (still image content search unit 411-1 to memo content search unit 411-4). As described above, for example, an image obtained by reducing a still image is generated as a thumbnail image of still image content, and an image obtained by reducing the image of the first frame is generated as a thumbnail image of moving image content. The thumbnail image generated by the thumbnail image generation unit 412 is output to the thumbnail image display control unit 413.

  Note that the thumbnail image generation unit 412 that generates the thumbnail image may be realized by the content processing software 381. In this case, the search result of the content by the search unit 411 is notified to the thumbnail image generation unit 412 of the content processing software 381, and a thumbnail image is generated in response to the notification. The generated thumbnail image is supplied to the thumbnail image display control unit 413 of the thumbnail display software 363 and displayed on the LCD 28.

  The thumbnail image display control unit 413 displays a list of thumbnail images supplied from the thumbnail image generation unit 412 in the thumbnail display area 241. When the thumbnail image display control unit 413 detects that any of the category selection buttons 261 to 264 is operated based on the output from the touch panel 36, the thumbnail of the content of the category corresponding to the operated button. Update the list display to exclude images.

  Further, the thumbnail image display control unit 413 taps the thumbnail image displayed in the thumbnail display area 241 based on the output from the touch panel 36, and when the user gives an instruction to reproduce the content, The reproduction request unit 414 is notified.

  Similar to the playback request unit 403 of the database processing software 371, the playback request unit 414 selects one of the still image content playback unit 421-1 to the memo content playback unit 421-4 according to the category of the content for which playback has been instructed. Requests to play content.

  Next, the operation of the PDA 1 will be described with reference to a flowchart.

  First, the database creation process executed by the data processing software 371 will be described with reference to the flowchart of FIG.

  In step S <b> 1, the database configuration information management unit 401 determines, based on the output from the touch panel 36, whether there is an input by the user, such as input of handwritten characters or pasting of a thumbnail image.

  If it is determined in step S1 that there is an input by the user, the process proceeds to step S2, and the database configuration information management unit 401 updates the database configuration information managed by itself according to the input. In step S <b> 2, with the update of the database configuration information by the database configuration information management unit 401, the update is reflected in the database display by the database display control unit 402.

  Thus, for example, when a curved handwritten character is input by the user, the coordinates, color, and pen thickness representing the input position of the handwritten character are registered in the database configuration information. Also, the newly registered information is reflected in the database display, and an image 231 as shown in FIG. 8 is displayed on the LCD 28.

  If it is determined in step S1 that there is no input from the user, the process in step S2 is skipped.

  In step S3, the display request unit 404 determines whether a list of thumbnail images has been displayed. If it is determined that the thumbnail image list has not yet been displayed, the process proceeds to step S4.

  In step S <b> 4, the display request unit 404 determines whether or not an instruction to display a list of thumbnail images has been given based on the output from the touch panel 36.

  If it is determined in step S4 that display of a list of thumbnail images has been instructed because the list display button 221 has been operated, the display request unit 404 proceeds to step S5 to display the list of thumbnail images in the thumbnail display software 363. Request to (search unit 411).

  In response to this request, the thumbnail display software 363 displays a list of thumbnail images. Details of the processing by the thumbnail display software 363 will be described later with reference to the flowchart of FIG.

  In step S <b> 6, the database configuration information management unit 401 determines whether the thumbnail image pasting to the database is notified from the thumbnail image display control unit 413 of the thumbnail display software 363. When a thumbnail image selected from the list of thumbnail images displayed in the thumbnail display area 241 is pasted in, for example, the memo creation area 211 by drag and drop, the thumbnail image display control unit 413 notifies that fact. (Step S31 in FIG. 24).

  If the database configuration information management unit 401 determines in step S6 that a thumbnail image has been pasted to the database, the database configuration information management unit 401 proceeds to step S7 and updates the database configuration information. Also at this time, the update of the database configuration information is reflected on the database display by the database display control unit 402.

Thus, for example, as shown in FIG. 9, when the thumbnail image 253 is pasted from the thumbnail display area 241 to the position P ₁ by drag and drop, the data of the content main body represented by the thumbnail image 253 is recorded. Link information representing a place, coordinates of the position P ₁ , etc. are registered in the database configuration information and reflected in the display (FIG. 10).

  If it is determined in step S4 that display of a list of thumbnail images is not instructed, the processes in steps S5 to S7 are skipped. If it is determined in step S6 that the thumbnail image is not pasted, the process in step S7 is skipped.

  On the other hand, if it is determined in step S3 that the list of thumbnail images has been displayed, the display request unit 404 proceeds to step S8 and determines whether or not an instruction to close the list of displayed thumbnail images has been issued. To do. By operating the list display button 221 when the list of thumbnail images is displayed, the user can close the list of thumbnail images.

  In step S8, if the display request unit 404 determines that it is not instructed to close the list of thumbnail images being displayed, the process proceeds to step S6 and executes the subsequent processing.

  If the display request unit 404 determines in step S8 that an instruction to close the list has been given, the process proceeds to step S9 and requests the thumbnail image display control unit 413 of the thumbnail display software 363 to close the list of thumbnail images. . In response to this request, the thumbnail display software 363 erases the list of thumbnail images. Thereafter, the process proceeds to step S10.

  In step S10, the database configuration information management unit 401 determines whether or not the user has instructed the reproduction of the content pasted in the database, and the thumbnail image pasted in the database has been tapped. If it is determined that the reproduction of the represented content has been instructed, the reproduction request unit 403 is notified of this.

  In step S11, the reproduction request unit 403 requests the content processing software 381 to reproduce the content. When the thumbnail image of the still image content is tapped, the reproduction request unit 403 requests the still image content reproduction unit 421-1 to reproduce the still image content. When the thumbnail image of the moving image content is tapped, the reproduction request unit 403 reproduces the moving image content. Requests playback of moving image content to the unit 421-2. When the thumbnail image of the audio content is tapped, the reproduction request unit 403 requests the audio content reproduction unit 421-3 to reproduce the audio content. When the thumbnail image of the memo is tapped, the reproduction request unit 403 -4 requests the playback of a memo.

  In step S12, the database configuration information management unit 401 determines whether or not to end the creation of the database. If it is determined not to end the process, the database configuration information management unit 401 returns to step S1 and repeats the subsequent processing.

  On the other hand, in step S12, the database configuration information management unit 401 is instructed to return to the main screen in FIG. 6, for example. The data is stored in the storage unit 139 and the process is terminated.

  Next, a thumbnail image display control process executed by the thumbnail display software 363 will be described with reference to a flowchart of FIG.

  This process is started when there is a request from the display request unit 404 of the database processing software 371 (step S5 in FIG. 23).

  In step S <b> 21, the search unit 411 searches for content in all categories that can be pasted to the database, with content stored in the storage unit 139, MS 3, or the like as a target.

  Specifically, the still image content search unit 411-1 searches for still image content, and the moving image content search unit 411-2 searches for moving image content. The audio content search unit 411-3 searches for audio content, and the memo content search unit 411-4 searches for memo content. The respective search results by the still image content search unit 411-1 to the memo content search unit 411-4 are output to the thumbnail image generation unit 412.

  In step S <b> 22, the thumbnail image generation unit 412 generates thumbnail images of the contents of the respective categories, and outputs the generated thumbnail images to the thumbnail image display control unit 413. As described above, when the thumbnail image generation unit 412 is realized by the content processing software 381, the search result in step S21 is notified to the thumbnail image generation unit 412 and a thumbnail image is generated.

  In step S23, the thumbnail image display control unit 413 displays a list of thumbnail images. Thereby, as shown in FIG. 9, a thumbnail display area 241 is formed on the LCD 28, and a list of thumbnail images is displayed there.

  In step S24, the thumbnail image display control unit 413 determines whether a thumbnail image category has been selected based on the output from the touch panel 36, and any of the category selection buttons 261 to 264 is operated. If it is determined that the category has been selected, the process proceeds to step S25.

  In step S <b> 25, the thumbnail image display control unit 413 updates the display of the thumbnail image according to the input by the user. For example, when the category selection button 261 is operated, the thumbnail image display control unit 413 updates the display by removing the thumbnail image of the still image content from the already displayed thumbnail images, and the category selection button 262. When is operated, the display is updated by removing the thumbnail image of the video content. Similarly, when the category selection buttons 263 and 264 are operated, the display is updated by removing the thumbnail images of the memo and the audio content.

  If it is determined in step S24 that no category has been selected, the process in step S25 is skipped.

  In step S <b> 26, the thumbnail image display control unit 413 determines, based on the output from the touch panel 36, whether or not the reproduction of the content displaying the thumbnail image in the thumbnail display area 241 has been instructed.

  If the thumbnail image has been tapped, if it is determined in step S26 that reproduction of the content represented by the thumbnail image has been instructed, the thumbnail image display control unit 413 notifies the reproduction request unit 414 of this.

  In step S27, the reproduction request unit 414 requests the content processing software 381 to reproduce the content. When the thumbnail image of the still image content is tapped, the reproduction request unit 414 requests the still image content reproduction unit 421-1 to reproduce the still image content. When the thumbnail image of the moving image content is tapped, the reproduction request unit 414 reproduces the moving image content. Requests playback of moving image content to the unit 421-2. When the thumbnail image of the audio content is tapped, the reproduction request unit 414 requests the audio content reproduction unit 421-3 to reproduce the audio content. When the thumbnail image of the memo is tapped, the reproduction request unit 414 -4 requests the playback of a memo.

  If it is determined in step S26 that content reproduction has not been instructed, the process of step S27 is skipped.

  In step S28, the thumbnail image display control unit 413 determines whether or not the tip of the stylus 2 is pressed on the thumbnail image displayed in the thumbnail display area 241. In S29, the display position of the thumbnail image is moved in conjunction with the movement of the stylus 2.

  In step S30, the thumbnail image display control unit 413 determines whether or not the tip of the stylus 2 has been pressed against the thumbnail image, that is, whether or not the tip of the stylus 2 has been separated from the surface of the LCD 28, and the stylus 2 If it is determined that the tip of the display is not separated from the surface of the LCD 28, the process returns to step S29, and the movement of the display position is repeated.

  On the other hand, if the thumbnail image display control unit 413 determines in step S30 that the tip of the stylus 2 has been moved away from the surface of the LCD 28 and the thumbnail image has been moved onto the database being created, the process proceeds to step S31, where database processing is performed. It requests the database configuration information management unit 401 of the software 371 to paste a thumbnail image.

  At this time, the thumbnail image display control unit 413 notifies the database configuration information management unit 401 of various information such as information indicating the position of the thumbnail image destination and link information of the thumbnail image.

  After such a thumbnail image pasting notification has been made, or when it is determined in step S28 that the tip of the stylus 2 is not pressed against the thumbnail image, the process proceeds to step S32.

  In step S32, the thumbnail image display control unit 413 determines whether or not it is requested to close the list of thumbnail images. If it is determined that the thumbnail image list is not requested, the process returns to step S26 and repeats the subsequent processing.

  If the thumbnail image display control unit 413 determines in step S32 that it is requested to close the list of thumbnail images, the thumbnail image display control unit 413 closes the list and ends the processing. This request is notified from the display request unit 404 of the database processing software 371 (step S9 in FIG. 23).

  Next, content reproduction processing executed by the content processing software 381 will be described with reference to the flowchart of FIG.

  For example, when this process is executed by the still image content processing software 381-1, the still image content reproduction unit 421-1 determines whether reproduction (preview) of the still image content is requested in step S41. And wait until it is determined that it has been requested.

  When the thumbnail image of the still image content pasted in the database is tapped, or when the thumbnail image of the still image content displayed in the thumbnail display area 241 is tapped, the playback request unit of the database processing software 371 403, the playback request unit 414 of the thumbnail display software 363 requests the playback of the still image content (step S11 in FIG. 23 and step S27 in FIG. 24). The request from the reproduction request unit 403 and the reproduction request unit 414 includes information indicating the storage position of the content body.

  When a thumbnail image is tapped, content playback does not start immediately, but when the thumbnail image is tapped, there is a menu indicating the contents of operations that can be selected by the user for the tapped content. The content may be displayed after the operation is displayed and a certain operation is selected from the menu. In the menu displayed when the thumbnail image is tapped, for example, playback / peel / enlargement / reduction / deletion of the content is prepared as an operation that can be selected by the user.

  If the still image content reproduction unit 421-1 determines in step S41 that reproduction of the still image content has been requested, the process proceeds to step S42 and is based on information included in the requests from the reproduction request unit 403 and the reproduction request unit 414. The data of the content body is acquired and the playback is started.

  Thereby, a preview of a still image as shown in FIG. 11 is displayed on the LCD 28, for example. The still image content reproduction unit 421-1 repeats the above processing to reproduce the still image content.

  Similar processing is performed on the content of each category by the moving image content playback unit 421-2, the audio content playback unit 421-3, and the memo content playback unit 421-4.

  In the above, the content pasted on the database is the content of a still image, a moving image, sound, and a memo (when creating a schedule), but the content that can be pasted is not limited to these. For example, various kinds of information such as the application icon 204 of FIG. 6 and a pasting image (for example, a star image) prepared in advance may be pasted as content. For example, the application icon 204 can be pasted on a memo and the software can be directly activated from the displayed memo by using it.

  Further, so-called PIM (Personal Information Manager) information such as one schedule item registered in the schedule table and one address information registered in the address book may be pasted into the database as content.

  Next, switching of the display of the thumbnail display area 241 will be described.

  As described above, a thumbnail image representing the searched content is displayed in the thumbnail display area 241. The display of the thumbnail display area 241 is switched in conjunction with the database screen display displayed above it. It has come to be able to.

  For example, when the calendar is displayed on a monthly basis and the user moves the cursor displayed on the calendar date, the cursor is selected by the cursor in conjunction with the movement of the cursor. The display of the thumbnail display area 241 is switched so that thumbnail images of content whose date is the creation date are displayed.

  In other words, information such as a memo, a still image, and audio is added with attribute information as creation date (“shooting date” for still images and “recording date” for audio). The display is switched with reference to the information.

  Thereby, for example, when the user registers that there is a meeting as a schedule for a certain day, and the voice recorded at the meeting is recorded in the PDA 1, the user selects the meeting date with the cursor, A thumbnail image of the audio of the conference can be displayed in the thumbnail display area 241 below it. That is, the user can easily find and play the target content from the “meeting” schedule displayed on the schedule.

  In addition, when the user selects a predetermined date from the calendar displayed in units of months, a certain date, so that a thumbnail image of content that does not have that date as the creation date can also be displayed, Content can also be associated (note that pasting the above-described thumbnail image to the schedule is associating the content with the database of the schedule).

  Therefore, when the user selects a certain date with the cursor, thumbnail images are arranged and displayed centering on the thumbnail image of the content associated with the date or the thumbnail image of the content having the date as the creation date. .

  Hereinafter, switching of the display of the thumbnail display area 241 will be described with reference to the drawings.

  FIG. 26 is a diagram showing an example of a daily schedule table display screen.

  The number “2004 01 04” displayed at the upper left indicates that the schedule displayed below is for January 4, 2004. Note that the screen in FIG. 26 is the same as the screen described with reference to FIG. 17 and the like, and redundant description is omitted.

  As shown in FIG. 26, “Meeting” is registered as a schedule 501 in the column from 13:00 to 14:00 on January 4, 2004. This is input in the same manner as the schedule 321 in FIG.

  In addition, a thumbnail display area 241 is displayed on the screen of FIG. 26, and five thumbnail images 511 to 515 are displayed there.

  Of the thumbnail images 511 to 515, the center thumbnail image 513 is selected by the cursor 521, and half of the left thumbnail image 511 and the right thumbnail image 515 are cut off. In addition to the five images shown in FIG. 26, a larger number of thumbnail images are virtually arranged in a band shape, and only those within the thumbnail display area 241 are actually displayed.

  The user can switch the display range of the thumbnail images arranged in this way by operating the scroll bar displayed under the cursor 521. For example, the entire thumbnail image 511 or the thumbnail image 515 is displayed. You can make it.

In the state of FIG. 26, when the thumbnail image 513 is moved to the position P ₃ on the scheduled input area 301, the thumbnail image 513 is pasted to the position P ₃ as shown in FIG. 27 (January 4, 2004). The content represented by the thumbnail image 513 is associated with the schedule of the day).

  The thumbnail image 513 is an image representing a database of memos, and as shown in FIG. 27, the thumbnail image 513 pasted in a schedule is selected, or the thumbnail image 513 displayed in the thumbnail display area 241 is selected. By doing so, the user can enlarge the memo.

  FIG. 28 is a diagram illustrating an example of a screen in which a memo whose contents are represented by a thumbnail image 513 is enlarged and displayed. In this way, the user can display the content in an enlarged manner, confirm the details, and add an edit. Note that the screen of FIG. 28 corresponds to, for example, the screen of FIG.

  In the thumbnail display area 241, the thumbnail images are basically arranged in order of creation date from the left to the right. As described above, the user associates a certain date with the content and customizes the display of the thumbnail image. can do.

  This date association is performed, for example, when the user sets the detailed information of the content in a state where the content is enlarged and displayed as shown in FIG.

  FIG. 29 is an example of a screen that displays detailed information of content.

  When a predetermined operation is performed in the state of the screen of FIG. 28, as shown in FIG. 29, a window 531 for displaying the details of the page (contents) is superimposed on the content of the handwritten map displayed at that time. Is displayed.

  By operating the OK button 541 displayed below the window 531, the user can reflect the setting of the contents described in the window 531 on the display, and cancel the setting by operating the cancel button 542. can do. When the OK button 541 and the cancel button 542 are operated, the window 531 is closed and the screen returns to the screen of FIG.

  In the example of FIG. 29, the window 531 has a title (title of the memo in FIG. 28) “0401040000” and a creation date “January 4, 2004” (04/01/04) “10:28”. "28 seconds" (10:28:28), "10:57:11" (10:57:11) with update date and time of "January 4, 2004" (04/01/04), amount of content data Is displayed as “10 KB”. As described above, date information such as a creation date and an update date is added to each content including a memo.

  Further, the user can set the date and time of the schedule table to which the content is associated with the background color of the memo (the color of the ground in FIG. 12B), the alarm on / off, and the details of the content being displayed. Has been made. In the example of FIG. 29, “January 26, 2004” is entered in the date field 551, and “9:28” (09:28) is entered in the time field 552.

  That is, in this case, the content in FIG. 28 is associated with “January 26, 2004”, and when the user selects, for example, the January 26 column from the schedule displayed on a monthly basis, In the thumbnail display area 241 below the table, a thumbnail image representing the content of FIG. 28 is displayed regardless of the creation date of “January 4”.

  FIG. 30 shows a screen that is displayed when the date field 551 in FIG. 29 is tapped with the stylus 2, and a window 561 is displayed over the contents instead of the window 531 that has been displayed so far.

  When the date for associating the content is selected from the window 561 or when the cancel button 571 is operated, the window 561 is closed and the display returns to the display of FIG. The today button 572 is operated when associating with the date on which the date and time is set.

  As shown in FIG. 30, 12 buttons operated when selecting each month from January to December are displayed above the window 561, and one month selected therefrom is displayed. A calendar is displayed below the 12 buttons.

  In the example of FIG. 30, January is selected, and the 26th (January 26) is selected by the cursor 581 as the date for associating the content. The cursor 581 is displayed on the date selected by the user by tapping with the stylus 2 or the like.

  Thus, the user can easily associate the date with the content simply by selecting the date from the displayed calendar. Hereinafter, the date and time associated with the content are also referred to as a schedule date and a schedule time as appropriate.

  FIG. 31 is a diagram showing an example of a monthly schedule table screen.

  In the schedule input area 301 of FIG. 31, a schedule table for January is mainly displayed. “Meet ...” (meeting) is displayed in the 4th day column, and “Kaimono” is displayed in the 15th column. However, “Meet ...” (meeting) is displayed in the 26th column.

  In the case of displaying the schedule on a monthly basis, the contents of the schedule are displayed in the date column where the schedule is input. In addition, an icon representing the date is displayed in the date column where there is content whose creation date is the date and the date column where the schedule date is set.

  Icons 601 to 604 in FIG. 31 represent them. For example, the icon 601 displayed in the January 1st column, the icon 602 displayed in the January 4th column, and the icon 603 displayed in the January 24th column create respective dates. Indicates that there is content for the day. Further, the icon 604 displayed in the January 26 column indicates that there is content with the 26th as a schedule date.

  The icon indicating the creation date of the content (for example, icons 601 to 603) and the icon indicating the schedule date (for example, icon 603) may be the same, or the content can be visually identified by the user. As such, the colors and shapes may be different.

  From the monthly schedule of FIG. 31, the user can confirm a schedule registered on the date or newly register a schedule by selecting a predetermined date column. For example, when the 4th day column in FIG. 31 is tapped with the stylus 2, the display of the schedule input area 301 is switched to the display shown in FIG.

  Further, the user can move the cursor 591 displayed on one date by rotating the jog dial 25 (FIG. 3), and press the jog dial 25 in the direction inside the housing of the PDA 1. Thus, the schedule of the date selected by the cursor 591 can be displayed in the schedule input area 301 in the same manner as when the date is tapped.

  For example, when the jog dial 25 is rotated, the cursor 591 in the 26th day column of FIG. 31 moves on the 25th, 24th, 23rd,... ), Or 27th, 28th, 29th,... (Downward rotation).

  In conjunction with the movement of the cursor 591, the thumbnail images displayed in the thumbnail display area 241 are also switched.

  Here, switching of the display of the thumbnail display area 241 will be described.

  FIG. 32 is a diagram showing only the thumbnail display area 241.

  Thumbnail images 631 and 632 are thumbnail images of content whose creation date is January 1st, and thumbnail images 633, 634 and 635 are thumbnail images of content whose creation date is January 4th.

  Basically (when there is no thumbnail image of content for which a schedule date is set), the thumbnail images displayed in the thumbnail display area 241 are arranged in this order of content creation. If there are multiple contents with the same date as the creation date, the order of arrangement is determined before and after the creation time.

  When January 1st is selected from the schedule table displayed above the thumbnail display area 241 with the cursor 591 (FIG. 31), the top of the thumbnail images of the content having the creation date as 1st ( The thumbnail image 631 on the left side is displayed at the center of the five thumbnail images (the contents having January 1 as the creation date are only two contents represented by the thumbnail images 631 and 632 in FIG. 32). If there is, the thumbnail images 631 to 635 are scrolled to the right by the amount of two thumbnail images from the state of FIG. 32).

  When the jog dial 25 is rotated and the cursor 591 moves to the January 4th column, the thumbnail image 633 at the head of the thumbnail images of the content having the creation date of the 4th is positioned at the center. The display is switched to the display of FIG.

  When the jog dial 25 is continuously rotated (for example, operated downward) from the state of FIG. 32 and the cursor 591 moves on January 24, the thumbnail of the content having January 24 as the creation date is also the same. The display is switched so that the image is in the center.

  In addition, when the cursor 591 moves on January 26, as shown in FIG. 33, content in which 26th is set as the schedule date even though January 4 is the creation date. The display is switched so that the thumbnail image 513 is in the center of the thumbnail display area 241. This state is the same as the state of the thumbnail display area 241 in FIG.

  In this way, since the schedule date can be set, for example, when the user uses the material created in the meeting on January 4 (the memo in FIG. 28) in the meeting on the 26th, the user's schedule table is displayed. By setting the day as 26 days, the user can easily find the material by simply selecting the 26th day of the meeting with the cursor 591.

  When the thumbnail images are simply arranged in order of creation date, the user needs to search for the meeting materials created in advance while remembering the creation date. However, the user can remember the creation date by setting the schedule date. You can search for materials by looking at the schedule of the 26th meeting registered in the schedule.

  In FIG. 33, thumbnail images 611 and 612 are thumbnail images of content whose creation date is January 24, for example, and thumbnail images 613 and 614 are thumbnails of content whose creation date is 26th, for example. It is an image.

  In this way, when there is content having the date as a calendar date and content having the date as a creation date on one day, the content of the calendar date is given priority and the thumbnail image of the content having the date as the calendar date. The display is controlled so that is at the top.

  Therefore, when January 26 is selected with the cursor 591, as shown in FIG. 33, the 26th is a schedule table than the thumbnail images 613 and 614 that are the thumbnail images of the contents having the 26th as the creation date. A thumbnail image 513 that is a thumbnail image of the content to be dated is preferentially displayed in the center.

  In addition, when there are a plurality of contents having the same day as a schedule date, the contents are rearranged according to the schedule time, creation time, and the like.

  The switching of the thumbnail image display as described above is also performed when a weekly schedule is displayed as shown in FIG.

  FIG. 34 is a diagram showing an example of a schedule for the week from January 25 to January 31 in FIG.

  Also in this case, the user can sequentially move the cursor 631 by rotating the jog dial 25. In conjunction with the movement of the cursor 631, the display of thumbnail images in the thumbnail display area 241 is also switched.

  In the example of FIG. 34, the icon 641 displayed in the 26th day column indicates that there is content with 26th as a schedule date, as in FIG. When the 26th is selected by the cursor 631, the display is switched so that the thumbnail image 513, which is the thumbnail image of the content having that date as the schedule date, is located at the center.

  FIG. 35 is a block diagram illustrating an example of a functional configuration of each software for switching the display of thumbnail images as described above.

  Each functional unit shown in FIG. 35 is the same as the configuration in FIG. 22 except that the content management unit 651 is realized by the content processing software 381.

  The content management unit 651 manages the content stored in the MS 3 or the like, and sets the schedule date and time input from the screen of FIG. 29, for example.

  36 and 37 are diagrams showing examples of the data structure of content managed by the content management unit 651. FIG.

  FIG. 36 is a diagram illustrating an example of a data structure of a handwritten memo created by the user. In the header added to the handwritten memo data, information indicating the creation date, information indicating the editing date, information indicating the schedule date and time, and other attribute information are described.

  When the schedule date and time is set by the user, information representing the set date and time is described in the header of each content having the same data structure as in FIG.

  FIG. 38 is a diagram illustrating an example of the data structure of a still image. Exif (Exchangeable image file format) information is added to the image data body. Exif information is the main information consisting of information such as the manufacturer name of the digital camera that shot the image, date (shooting date), etc., sub-information consisting of shutter speed at the time of shooting, information indicating the version of Exif, thumbnail information, extended information Consists of. Information on the schedule date and time set by the user is described in the extended information.

  Next, the schedule date and time registration processing performed by the content management unit 651 of the content processing software 381 will be described with reference to the flowchart of FIG.

  In step S301, the content management unit 651 displays the content details screen shown in FIG. 29 in response to an instruction from the user, proceeds to step S302, and determines whether or not setting of the schedule date and time has been selected. . That is, in this case, the content management unit 651 controls the display on the LCD 28 and also monitors the user input to the touch panel 36.

  If it is determined in step S302 that the schedule date and time setting has not been selected, the process proceeds to step S303, the process corresponding to the user operation is performed, and the processes in steps S304 to S306 are skipped.

  On the other hand, for example, when the date field 551 in FIG. 29 is tapped with the stylus 2, if it is determined in step S302 that the setting of the schedule date is selected, the process proceeds to step S304, and the content management unit 651 displays Display the selection screen. In step S304, when the time column 552 is tapped, a screen for selecting a time is displayed in the same manner.

  In step S305, the content management unit 651 determines whether a date as a schedule date has been selected or a time as a schedule time has been selected. For example, the content management unit 651 determines a predetermined day from the screen of FIG. Until is selected, the process returns to step S304 to continue displaying the selection screen.

  If it is determined in step S305 that the schedule date has been selected, the process proceeds to step S306, and the content management unit 651 sets the schedule date according to the selection by the user.

  Here, when the user sets the schedule date and time in the memo, as shown in FIG. 36, when the schedule date and time information is set in the header and the schedule date and time is set in the still image, As shown in 37, schedule date information is set as extended information of the Exif information.

  In step S307, the content management unit 651 determines whether or not to close the detail screen is selected. If it is determined that the detail screen is not selected, the content management unit 651 returns to step S301 and repeats the above-described processing.

  If the content management unit 651 determines that the close of the detail screen has been selected because the OK button 541 displayed on the detail screen has been operated, the content management unit 651 ends the processing.

  Next, display processing of icons (such as the icon 604 displayed on the schedule) performed by the database processing software 371 will be described with reference to the flowchart of FIG. This process is performed when the monthly, weekly, and daily schedule screens are displayed.

  In step S321, the database display control unit 402 selects one of the contents managed by the content management unit 651 of the content processing software 381, and proceeds to step S322, where there is content that has not yet been selected. Determine whether or not.

  When all the contents are selected and the processing described later is performed for all the contents, the database display control unit 402 determines in step S322 that there is no content, and ends the process.

  If it is determined in step S322 that there is content that has not been selected, the database display control unit 402 proceeds to step S323, and determines whether or not a schedule date is set for one content selected in step S321. .

  In step S323, when the database display control unit 402 determines that a schedule date is set for the selected content, the database display control unit 402 proceeds to step S324, and determines the schedule date from the content header or from the Exif information. get.

  On the other hand, if the database display control unit 402 determines in step S323 that no schedule date has been set for the selected content, the database display control unit 402 proceeds to step S325, and determines the creation date from the content header or Exif information. Get from.

  When the date is acquired in steps S324 and S325, the database display control unit 402 proceeds to step S326, and the acquired schedule date is a date included in the month / week / day displayed in the schedule input area 301. It is determined whether or not there is.

  If the database display control unit 402 determines in step S326 that the acquired schedule date is not a day included in the month / week / day displayed in the schedule input area 301, the database display control unit 402 returns to step S321 and thereafter Repeat the process.

  On the other hand, if the database display control unit 402 determines in step S326 that the acquired schedule date is a day included in the month / week / day displayed in the schedule input area 301, the process proceeds to step S327. Display an icon in the day column.

  Thus, as shown in FIG. 31, when the schedule for January 2004 is displayed in the schedule input area 301, the fields for January 1, 4, 24, and 26 are displayed in the respective fields. Icons 601 to 604 indicating that there is content whose date is the creation date or the schedule date are displayed.

  Next, a thumbnail image display process performed by the thumbnail processing software 363 will be described with reference to a flowchart of FIG.

  This process is started, for example, when the cursor 591 is on a date (date on which an icon is displayed) that is a schedule date or a creation date of content.

  In step S341, the thumbnail image display control unit 413 of the thumbnail display software 363 sets a display reference date. Here, the display reference date is the date selected as the schedule date or creation date of the content selected by the cursor 591.

  In step S342, the thumbnail image display control unit 413 selects one of the contents managed by the content management unit 651 of the content processing software 381, and proceeds to step S343, where there is content that has not yet been selected. It is determined whether or not.

  When all the contents are selected and the process described later is performed for all the contents, the thumbnail image display control unit 413 determines in step S343 that no content exists, and ends the process.

  If it is determined in step S343 that there is content that has not been selected, the thumbnail image display control unit 413 proceeds to step S344, and determines whether a schedule date is set for one content selected in step S341. To do.

  In step S344, when the thumbnail image display control unit 413 determines that a schedule date is set for the selected content, the process proceeds to step S345, where the schedule date is determined from the content header or Exif information. Get from.

  On the other hand, if it is determined in step S344 that the schedule date has not been set for the selected content, the thumbnail image display control unit 413 proceeds to step S346 and determines the creation date from the content header or Exif. Obtain from information.

  When the date is acquired in steps S345 and S346, the thumbnail image display control unit 413 proceeds to step S347, arranges the content selected immediately before and the content selected so far, centering on the display reference date, and thumbnails. Select content to generate images.

  Here, the contents are arranged so that only the content having the date closer to the display reference date as the creation date or the content having the date closer to the display reference date as the schedule date centered on the display reference date is selected. . For example, only a predetermined number of contents such as 10 are selected, and by sequentially selecting one content (by repeating the process of step S432), it corresponds to that 10 contents. The lost content is excluded from the content for generating the thumbnail image.

  In step S348, the thumbnail image display control unit 413 determines whether or not the selected content is content for generating a thumbnail image based on the result of the arrangement in step S347, that is, than the content that has already been selected. Then, it is determined whether or not the content has a date close to the display reference date as a creation date or a display reference date.

  If the thumbnail image display control unit 413 determines in step S348 that the selected content is not content that generates a thumbnail image, the thumbnail image display control unit 413 returns to step S342 and repeats the above processing.

  On the other hand, when it is determined in step S348 that the selected content is content for generating a thumbnail image, the process proceeds to step S349, and the thumbnail image display control unit 413 generates a thumbnail image and displays the thumbnail image. The thumbnail image is generated by, for example, the thumbnail image generation unit 412.

  When there are multiple contents with the same date as the creation date, the display here will be sorted to display thumbnail images in the order of their creation time, or the day will be scheduled for a certain day. When there is a content that is a front date and a content that is the date of creation, rearrangement is performed so that the content on the scheduled date is preferentially displayed.

  Thus, for example, when the 26th day is selected by the cursor 591 on the schedule input area 301 in FIG. 31, the thumbnail image 513 of the content having the 26th as the display reference date and the date as the schedule date is close thereto. Thumbnail images 611 to 614 having the date (that day) as the creation date are created and displayed in the thumbnail area 241.

  In the above description, the thumbnail area 241 is formed below the LCD 28. However, as shown in FIGS. 41A and 41B, the thumbnail area 241 may be formed in a predetermined range on the right side or the left side of the LCD 28. In this case, the thumbnail images are arranged and displayed in the vertical direction.

  In addition, a schedule for each day is displayed in the schedule input area 301 formed on the left side of the LCD 28 in FIG. 41A, and a schedule for each week is displayed in the schedule input area 301 formed on the left side of the LCD 28 in FIG. 41B. Has been.

  Further, in the above, the pasting of the content to the database as described above is performed in the PDA 1, but in addition, it may be performed in various devices such as a mobile phone and a notebook personal computer. Good.

  The series of processes described above can be executed by hardware, but can also be executed by software.

  When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed in a general-purpose personal computer from a network or a recording medium.

  As shown in FIG. 5, this recording medium is composed only of a package medium made up of MS3, CF4, etc. on which a program is recorded, which is distributed to provide a program to the user, separately from the apparatus main body. Instead, it is configured by a ROM 132, a storage unit 139, and the like that are provided to the user in a state of being preinstalled in the apparatus main body and in which a program is recorded.

  In the present specification, the step of describing the program recorded in the recording medium is not limited to the processing performed in time series according to the described order, but is not necessarily performed in time series, either in parallel or individually. The process to be executed is also included.

It is a perspective view which shows the example of the external appearance of PDA of the state which closed the display part with respect to the main-body part. It is a perspective view which shows the example of the external appearance of PDA of the state which opened the display part with respect to the main-body part. It is a perspective view which shows the example of the external appearance of the back side of PDA.
