Description

  The present invention relates to a file management device, and more particularly to a file management device that manages content files on a calendar, an image display device that reproduces and displays content files, a processing method in these, and a program that causes a computer to execute the method.

  With the widespread use of digital still cameras, digital video cameras, and the like, there are increasing opportunities for users to create content files (still image files, moving image files, audio files, etc.) themselves. It is difficult for the user to memorize all such content files, and it is often considered that they are stored unorganized.

  Therefore, conventionally, there are apparatuses that organize content files by displaying representative images on a calendar based on the creation time of the content file, that is, the year, month, day, and time when the content file was created. For example, an information processing apparatus that displays a list of photographed image files for each photographing date and photographing time has been proposed (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2005-33711 (FIG. 31)

  In the above-described prior art, since the representative image is displayed on the calendar, the purpose is sufficiently fulfilled in a browsing method in which an image created on a specific day is recognized in advance and searched for with a purpose. .

  However, it is considered that such a conventional technique is not necessarily suitable for a browsing method in which a user can view and enjoy various content files in the past without assuming a specific day. That is, in the prior art, the concept of time direction is displayed on the display screen of the time axis range of each year, month, or day, even though the concept of time is called calendar. It is not represented in a consistent way as a user interface. Therefore, it is difficult for the user to recognize the time axis from the user interface. As a result, the user cannot intuitively search for the representative image and browse the representative image so as to take a walk.

  Further, in the prior art, since images displayed at a time are divided in units of one day, a representative image group that spans a plurality of days such as a trip cannot be browsed collectively.

  Accordingly, an object of the present invention is to provide a seamless user interface by unifying time-series directions when displaying a representative image of a content file on a calendar of each time axis range of year, month, and day. .

  The present invention has been made in order to solve the above problems, and a first aspect of the present invention is that representative image storage means for storing representative image data of a content file in association with the creation time of the content file, a year, A drawing means for drawing the representative image data at a position corresponding to the creation time with a calendar continuous across the boundary between the month and the day, and a time axis range and a position to be displayed on the calendar. Display state holding means for holding as a display state, scroll operation receiving means for receiving scroll operations in the time series direction of the calendar, and rendering the representative image data on the calendar based on the scroll operation and the display state. Control means for controlling the drawing means, the control means having the time axis range. If it is a unit, the representative image is drawn at a position corresponding to the creation time of the content file by dividing each day into time zones divided every hour, and corresponds to any creation date of the content file. The file management apparatus and the image display apparatus for controlling the drawing means so as to exclude the display date from the display target, and the file management method and program therefor.

  In this first aspect, when the time axis range is in units of days, the control means divides each day into time zones divided into hourly intervals at positions corresponding to the creation time of the content file. The drawing unit may be controlled so that the representative image is drawn and the creation time is displayed below the representative image.

  In the first aspect, the control means may include the desired date among the creation dates where the content file exists when there is no content file having a creation date corresponding to the desired date selected by the user. The drawing means may be controlled to draw on the day corresponding to the creation date closest to.

  Further, in this first aspect, when the creation date of the content file exists continuously in units of days, the control means displays a label at the head of the group with the continuous range as a group. As described above, the drawing means may be controlled.

  According to the present invention, when displaying a representative image of a content file on a calendar of each time axis range of year, month, and day, it is possible to provide a seamless user interface by unifying time-series directions. The effects can be achieved.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of a file management apparatus or an image display apparatus according to an embodiment of the present invention. The file management apparatus includes a content file storage unit 110, a thumbnail data storage unit 120, a calendar information storage unit 130, an acquisition unit 140, a drawing unit 150, a display unit 160, an operation reception unit 170, and a control unit. 180 and a display state holding unit 190.

  The content file storage unit 110 stores content files such as still image files, moving image files, and audio files. The content file holds attribute information such as the creation time of the content file as metadata. The creation time means all or part of the year, month, day, and time when the content file was created.

  The thumbnail data storage unit 120 stores thumbnail data of content files stored in the content file storage unit 110 as representative images. As thumbnail data, a reduced image of a still image file and a reduced image of a frame at a certain time are used for a moving image file. For the audio file, a visual effect image at a certain time can be used. The thumbnail data storage unit 120 preferably stores the thumbnail data in association with the creation time of the content file. Thereby, it is possible to quickly read out thumbnail data using the creation time as an index key.

  The calendar information storage unit 130 stores information (calendar information) necessary for creating a calendar. For example, this corresponds to the correspondence between dates and days of the week, information on holidays and leap years, and the like.

  The acquisition unit 140 accesses the content file storage unit 110, the thumbnail data storage unit 120, and the calendar information storage unit 130, and acquires the contents thereof.

  The drawing unit 150 draws a calendar based on the calendar information stored in the calendar information storage unit 130 and draws the thumbnail data stored in the thumbnail data storage unit 120 at a corresponding position on the calendar. is there. In addition, when the reproduction of the content file is requested via the thumbnail data, the drawing unit 150 draws the reproduction display of the content file.

  The display unit 160 displays the content drawn by the drawing unit 150. The display unit 160 can be realized by a display such as an LCD (Liquid Crystal Display). The display unit 160 may be configured to be integrated with the operation receiving unit 170 by a touch panel or the like.

  The operation reception unit 170 receives an operation input from the user. The operation accepting unit 170 is assumed to be a pointing device such as a mouse in the embodiment of the present invention, but may be realized as a touch panel integrated with the display unit 160.

  The control unit 180 controls the acquisition unit 140 and the drawing unit 150 in accordance with the operation input received by the operation reception unit 170. That is, the acquisition unit 140 acquires calendar information and thumbnail data necessary for drawing, and based on these, the drawing unit 150 draws thumbnail data at a corresponding position on the calendar. Further, when the reproduction of the content file is requested, the drawing unit 150 draws the reproduction display of the content file.

  The display state holding unit 190 holds the time axis range and position that are currently displayed on the calendar as the display state. As the time axis range, any one of year unit, month unit, and day unit can be used. The location can be represented by year, month, day and time. By holding the current display state in the display state holding unit 190, when the change of the time axis range is instructed, the changed time axis range and the current position can be grasped. The time axis range can be switched while maintaining

  FIG. 2 is a diagram showing an outline of a display mode in the embodiment of the present invention. FIG. 2A is a diagram illustrating a display mode example when year units are selected as the time axis range. The background year calendar 511 is continuous across years. Therefore, the year display screen 510 displays a part of the calendar 511.

  In each month of the calendar 511, thumbnail data 514 is drawn at a position corresponding to the creation month of the content file. As a drawing mode of the thumbnail data 514, one representative thumbnail data per month may be drawn. Further, as shown in FIG. 4, each month is further displayed in a calendar format, and the thumbnail data representing each day is displayed. May be drawn respectively.

  FIG. 2B is a diagram illustrating an example of a display mode when the monthly unit is selected as the time axis range. The monthly calendar 521 as a background is continuous across the months. Therefore, like the year display screen 510, the month display screen 520 displays a part of the calendar 521.

  On each day of the calendar 521, thumbnail data 524 is drawn at a position corresponding to the creation date of the content file. As a drawing mode of the thumbnail data 524, one representative thumbnail data may be drawn per day, or a plurality of thumbnail data may be drawn in a tile shape, for example.

  FIG. 2C is a diagram illustrating an example of a display mode when a day unit is selected as the time axis range. A daily calendar 531 as a background is continuous across days. Therefore, the day display screen 530 displays a part of the calendar 531 as in the year display screen 510 and the month display screen 520.

  Each day of the calendar 531 is divided into time zones divided every hour, and thumbnail data 534 is drawn at a position corresponding to the creation time of the content file. Further, the creation time may be displayed together with the thumbnail data 534. When there are a plurality of corresponding thumbnail data in the same time zone, all the thumbnail data are rendered in the order of creation time, for example. In addition, although the example which divided | segmented the time slot | zone for every hour was shown here, the unit of this division | segmentation can be set suitably.

  These display screens 510, 520, and 530 have a common time-series scroll operation, and move upward in time by an upward scroll operation that moves the display screen upward relative to the calendar. The display screen is moved in a new direction in time by a downward scroll operation for moving the display screen relatively downward with respect to the calendar. Therefore, it is possible to provide a user interface that can be used in the same scroll operation on any time axis range screen.

  These display screens 510, 520, and 530 have a calendar continuous across the year, month, and day boundaries as a background, and the display is not interrupted even when the boundaries are crossed by a scroll operation. Therefore, for example, when the unit of the time axis range is a monthly unit as shown in FIG. 2B, there is no need to return to the year display screen when shifting from the display of one month to the display of another month, or There is no need to explicitly press a button for displaying another month. That is, it is possible to provide a user interface that seamlessly performs display across the year, month, and day boundaries by a scroll operation.

  FIG. 3 is a diagram showing transition of the display screen in the embodiment of the present invention. In the embodiment of the present invention, a mouse having at least two left and right buttons will be described as an example of the operation receiving unit 170.

  FIG. 3A shows an example in which the year display screen 510 to the content display screen 540 are displayed on the same screen (window display screen). When the left button of the mouse is pressed, that is, a left click operation is performed with the cursor placed on a specific month region on the year display screen 510, the month display screen 520 for the specific month is displayed. Then, when the left click operation is performed with the cursor placed on a specific day area on the month display screen 520, the day display screen 530 for the specific day is displayed. That is, the time axis range changes so as to become finer by a left click operation.

  As described above, when the time axis range is changed by the left click operation and the display screen is changed, the control unit 180 updates the display state holding unit 190 to hold the new time axis range and position. Further, when the position to be displayed is changed by the scroll operation on each display screen, the control unit 180 updates the display state holding unit 190 to hold the new position.

  On the other hand, when the right button of the mouse is pressed on the day display screen 530, that is, a right click operation is performed, the month display screen 520 of the month to which the day belongs is displayed. When a right click operation is performed on the month display screen 520, the year display screen 510 of the year to which the month belongs is displayed. In other words, the time axis range changes so as to become rough by a right click operation.

  As described above, when the time axis range is changed by the right click operation and the display screen is changed, the control unit 180 reads out the display state held in the display state holding unit 190 and creates a new one based on the display state. The display unit 150 is caused to draw the display screen. Then, the control unit 180 updates the display state holding unit 190 to hold the time axis range of the new display screen.

  Further, when the left click operation is performed with the cursor placed on the specific thumbnail data 534 on the date display screen 530, the content display screen 540 for displaying the content file corresponding to the thumbnail data 534 is displayed. become. When a right-click operation is performed on the content display screen 540, a date display screen 530 for the creation date of the content file is displayed.

  FIG. 3B shows an example in which the content display screen 540 is displayed on another screen (window display screen). The transition from the year display screen 510 to the day display screen 530 and the transition from the day display screen 530 to the year display screen 510 are the same as in the example of FIG.

  When a left click operation is performed with the cursor placed on a specific thumbnail data 534 on the date display screen 530, a content display screen 540 for reproducing and displaying a content file corresponding to the thumbnail data 534 is displayed as another screen. Become so. At this time, the original day display screen 530 is maintained as it is.

  FIG. 4 is a diagram showing an example of the year display screen 510 in the embodiment of the present invention. The year display screen 510 includes an area 512 indicating a calendar structure and a calendar display area 513 having a year as a unit of a time axis range.

  In the area 512, the number of corresponding content files is shown for each creation year, and a breakdown for each creation month can also be displayed. When a creation year in this area 512 is selected, a year-by-year calendar for that year is displayed in the display area 513. In this example, the yearly calendar is divided into each month from January to December, and each month is divided into each day in which the days of the week are arranged in the horizontal direction. In each day, thumbnail data 514 representing the creation date is drawn.

  A scroll bar 516 is shown at the right end of the calendar display area 513. Since yearly calendars are continuous even across years, a calendar for another year can be displayed seamlessly by operating the scroll bar 516.

  A year display bar 515 is shown on the left side of the scroll bar 516. In the center of this year display bar 515, the year displayed in the calendar display area 513 is shown. In the upper part of the year display bar 515, the previous year is shown, and the next year is shown in the lower part. Since the yearly calendar is continuous even across years, this year display bar 515 is provided to clearly indicate the currently displayed year.

  Depending on the display form of the calendar display area 513, a plurality of years may be displayed on the same screen. In this case, the center of the year display bar 515 is defined as the year centering on the year with the largest display area. It can be displayed on In this case, it is conceivable that the display other than the central year is rendered inactive, for example, thinly drawn by gray-out.

  FIG. 5 is a diagram showing an example of the month display screen 520 in the embodiment of the present invention. The month display screen 520 includes an area 522 indicating a calendar structure and a calendar display area 523 using the month as a unit of the time axis range.

  In the area 522, the number of corresponding content files is shown for each creation year, and a breakdown for each creation month can also be displayed. When a creation month in this area 522 is selected, a monthly calendar for that month is displayed in the display area 523. In this example, a calendar for September is arranged in the horizontal direction from Sunday to Saturday and divided into each day from 1st to 30th. In each day, thumbnail data 524 representing the creation date is drawn.

  A scroll bar 526 is shown at the right end of the calendar display area 523. Since the monthly calendar is continuous even across months, the calendar of another month can be displayed seamlessly by operating the scroll bar 526.

  A month display bar 525 is shown on the left side of the scroll bar 526. In the center of the month display bar 525, the month displayed in the calendar display area 523 is shown. The month display bar 525 displays the previous month at the top and the next month at the bottom. Since the monthly calendar is continuous even across the months, this month display bar 525 is provided to clearly indicate the currently displayed month.

  Note that, due to the day of the week, a plurality of months are displayed on the same screen, but it may be displayed at the center of the month display bar 525 with the month having the largest display area as the center month. In this case, it is conceivable that the display other than the central month is rendered inactive and thinly drawn.

  FIG. 6 is a diagram showing an example of the day display screen 530 in the embodiment of the present invention. The date display screen 530 includes an area 532 showing a calendar structure and a calendar display area 533 having the date as a unit of the time axis range.

  In the area 532, the number of corresponding content files is shown for each creation year, and a breakdown for each creation month can also be displayed. As a modification, a breakdown for each creation date may also be displayed.

  In the calendar display area 533, each day is divided into time zones divided every hour, and thumbnail data 534 is drawn at a position corresponding to the creation time of the content file. In this example, the creation time is displayed below the thumbnail data 534.

  A scroll bar 536 is shown at the right end of the calendar display area 533. Since the daily calendar is continuous even across days, the calendar of another day can be displayed seamlessly by operating the scroll bar 536.

  However, if a date that does not correspond to the creation date is displayed as it is, it becomes necessary to repeat the scroll operation for a calendar that does not include the thumbnail data 534 at all. Therefore, in this example, days that do not correspond to the creation date of any content file are excluded from the calendar display area 533. In this case, when a specific day is left-clicked on the month display screen 520, a content file having a creation date corresponding to the specific day may not exist. In such a case, it is conceivable to display the date display screen 530 of the day corresponding to the nearest existing creation date. In particular, the closest creation date may be selected from the front on the time axis, that is, from a new direction in time.

  Conversely, if the creation date of the content file exists continuously in units of days, it is assumed that some event (for example, travel) spans multiple days, and the continuous range is grouped. It is desirable to summarize. A label 537 indicating the start date is displayed at the top of the group, and a label 538 indicating the last date is displayed at the end. The labels 537 and 538 can be colored as necessary. For example, it can be a blue label on Saturday, a red label on Sunday, and the like.

  A date display bar 535 is shown on the left side of the scroll bar 536. In the center of the day display bar 535, the date displayed in the calendar display area 533 is shown. The previous day is displayed at the top of the day display bar 535, and the next day is displayed at the bottom. Since the daily calendar is continuous even across days, this day display bar 535 is provided to clearly indicate the currently displayed day. However, the previous day and the next day mentioned here exclude the days that do not correspond to the creation date of any content file, as described above.

  When a plurality of days are displayed on the same screen, it may be possible to display the day with the largest display area as the day centered on the day display bar 535. In this case, it is conceivable that the display other than the central day is rendered inactive and thinly drawn.

  FIG. 7 is a diagram showing an example of the content display screen 540 according to the embodiment of the present invention. The content display screen 540 includes an area 542 showing thumbnail data and a content file reproduction display area 543.

  When specific thumbnail data is selected in area 542, a playback display of the content file corresponding to the thumbnail data is drawn in area 543. It is conceivable that thumbnail data belonging to the above-described group is arranged in the area 542 so that a reproduction display target can be selected from the thumbnail data.

  Note that the content file displayed in the area 543 can be an operation target such as enlargement / reduction by a tool group provided in the upper part.

  FIG. 8 is a diagram showing a display example of the tooltip in the embodiment of the present invention. When the cursor 517 is moved over a specific month in the calendar display area 513 of the year display screen 510, the specific month and the number of content files having the month as the creation month are displayed as a tool tip 518. The tool tip 518 may be displayed only for a short period of several seconds to 10 seconds, or may be continuously displayed until the cursor moves again.

  FIG. 9 is a diagram showing another display example of the tooltip in the embodiment of the present invention. When the cursor 527 is moved over a specific date in the calendar display area 523 of the month display screen 520, the specific date and the number of content files having the date as the creation date are displayed as a tool tip 528. The display period of the tool tip 528 is the same as that of the tool tip 518.

  FIG. 10 is a diagram showing a display example of superimposed display in the embodiment of the present invention. In the embodiment of the present invention, since each calendar is continuous across years, months, or days, there is a possibility that it is difficult to grasp the current display position when performing a scroll operation. Therefore, in the embodiment of the present invention, when the boundary of the unit of the time axis range is straddled during the scroll operation, the information regarding the unit serving as the center is displayed in a superimposed manner according to the unit.

  FIG. 10A shows an example of the year display screen 510. In this example, the year of the center and the number of content files having the year as the creation year are superimposed and displayed by crossing the year boundary by scroll operation. It is drawn as 519.

  FIG. 10B is an example of the month display screen 520. In this example, the month that is the center and the number of content files having the month as the creation month are superimposed and displayed by crossing the boundary of the month by the scroll operation. 529 is drawn.

  FIG. 10C shows an example of a day display screen 530. In this example, the date of the center and the number of content files having the date as the creation date are superimposed and displayed 539 by straddling the boundary of the day by the scroll operation. Is drawn as

  The superimposed displays 519, 529, and 539 may be temporarily displayed only for a short period of several seconds to 10 seconds, or may be continuously displayed until the boundary is crossed again.

  Next, the operation of the file management apparatus according to the embodiment of the present invention will be described with reference to the drawings.

  FIG. 13 is a diagram illustrating a processing procedure example of the scroll processing (step S930) according to the embodiment of the present invention. If the operation received by the operation reception unit 170 is a scroll operation (step S931), the control unit 180 instructs the drawing unit 150 to scroll the display screen (step S932). At that time, the control unit 180 updates the display state holding unit 190 so that the position of the display state indicates the position after scrolling.

  When scrolling, the unit boundary of the time axis range is exceeded (step S933), that is, the year boundary is exceeded on the year display screen 510, the month boundary is exceeded on the month display screen 520, or the day display screen 530 is exceeded. When the day boundary is exceeded, the control unit 180 draws the drawing unit 150 so that the display other than the new central unit (specific year, month, or day) is inactive (eg, grayed out). (Step S934). At the same time, the control unit 180 causes the drawing unit 150 to draw the superimposed display described with reference to FIG. 10 (step S935). That is, the control unit 180 causes the acquisition unit 140 to acquire information about a new central unit from the thumbnail data storage unit 120 and causes the drawing unit 150 to draw the information as a superimposed display.

  FIG. 14 is a diagram illustrating a processing procedure example of the cursor movement processing (step S940) according to the embodiment of the present invention. If the operation received by the operation reception unit 170 is a cursor movement operation (step S941), the control unit 180 instructs the drawing unit 150 to move the cursor (step S942).

  When the cursor moves (mouse over) on any unit of the time axis range on the display screen by the cursor movement processing (step S943), the control unit 180 uses the tool described with reference to FIGS. The drawing unit 150 is instructed to draw as a chip (step S944).

  As described above, according to the embodiment of the present invention, the user who seamlessly displays across the year, month, and day boundaries by the same scrolling operation on the screen of any time axis range in the operation receiving unit 170. An interface can be provided. In addition, by holding the current display state in the display state holding unit 190, when the change of the time axis range is instructed, the changed time axis range and the current position can be grasped. The time axis range can be switched while maintaining the position.
