Thumbnails of all pieces of content can be caused to be displayed by a scroll bar 5034 in the display screen 503 being pressed by a user operation. In addition, a display 5032 showing the number of pieces of content corresponding to the applicable date/time may be made together with a display 5031 showing date/time information in the upper part of the display screen 503. Further, a focus display 5033 causing content selected by the user to be displayed explicitly may be made.

In addition, for a thumbnail of content selected by the user, a display including the start time and end time of the content may be caused to be made together with the thumbnail. Further, a predetermined period in which thumbnails of content to be displayed are caused to be displayed may be scaled up or scaled down by a scaling button 5035 being selected. That is, if the scale-down button is selected in the display screen 503 that causes all thumbnails of content to be displayed, thumbnails of content contained in a predetermined week can be caused to be displayed or those of content contained in a predetermined day can be caused to be displayed. The scaling button 5035 may be a button such as a remote control operated by the user.

FIG. 8 is an explanatory view illustrating a display screen that causes thumbnails of content of a specific week to be displayed. FIG. 9 is an explanatory view illustrating a display screen that causes thumbnails of content of a specific day to be displayed. When, as shown in FIG. 8, thumbnails of content corresponding to dates of a specific week should be caused to be displayed (display screen 504), each thumbnail to be displayed may be enlarged and further, the title of content may also be displayed together with the thumbnail when compared with a case in which thumbnails of all content are caused to be displayed (display screen 503).

Further, as shown in FIG. 9, thumbnails of content corresponding to the date of a specific day should be caused to be displayed (display screen 505), each thumbnail to be displayed may be enlarged when compared with a case in which thumbnails of content corresponding to the date of a specific week should be caused to be displayed (display screen 504).

Like the display screen 504, the title of content may be caused to be displayed together with the thumbnail of the content or a display 5051 showing the presence of recorded content may be made together with a date/time display. The display 5051 showing the presence of recorded content may be made to visually show a recorded time of content. Accordingly, the user can intuitively know content of when and how long recording time was recorded.

Next, a case in which the display apparatus 200 is caused to display thumbnails of a plurality of pieces of content by associating with the date display in which date information of a predetermined period is made to be arranged and displayed on a calendar with reference to FIG. 10 and FIG. 11. FIG. 10 is an explanatory view illustrating a display screen 506 causing thumbnails of a plurality of pieces of content to be arranged and displayed on a calendar. As shown in FIG. 10, thumbnails of the plurality of pieces of content are arranged and displayed on a calendar together with the date display.

If thumbnails of a plurality of pieces of content for the same date on the calendar are present, one of the plurality of thumbnails may be made to be displayed. The thumbnail to be represented may be one of content with the earliest recording time or one containing a person's face. If representative content is preset by a user operation, a thumbnail of the applicable content may be displayed.

In addition, the scale of displayed date/time of displayed content may be changed by a scaling button 5062 being selected. For example, if the scale-down button is selected in the display screen 506 in which thumbnails of content are displayed on the calendar, thumbnails of content contained in a specific week or specific day may be caused to be displayed. The scaling button 5062 may be a button such as a remote control operated by the user.

As show, for example, in a display screen 507 in FIG. 11, together with a date display 5017 showing a specific date, thumbnails of content corresponding to the applicable date may be caused to be displayed. Further, for example, the date display may be made to be changeable by operating up/down arrow keys of a remote control or the like. If a date display is changed, the display of thumbnails of content is changed to those of content corresponding to the applicable date together with the date change.

Further, the displayed week or month may be made to be changeable by pressing right/left arrow keys, a “<<” key, or a “>>” key of a remote control or the like. Accordingly, the user can intuitively grasp what content is recorded by associating with dates or the like.

Next, a case in which thumbnails of content are arranged clockwise in descending order of time and displayed in the display apparatus 200 will be described with reference to FIG. 12 and FIG. 13. FIG. 12 displays thumbnails of content of a specific date by arranging thumbnails 5081 of content clockwise in descending order of time. Together with the thumbnails 5081 of content, a display 5082 showing the length of content may also be made. The length of content may be displayed by the length of a portion on a circumference. Further, the title of the thumbnail 5081 of content selected by the user may be displayed or a display 5083 showing the start time and end time may be made.

A display screen 508 may be made to be displayed by a screen being changed from the display screens 501 to 507 shown in FIG. 5 to FIG. 11 in accordance with a user operation. For example, when a thumbnail of content displayed in the display screen 501 in chronological form shown in FIG. 5 is selected by a user operation, the display screen 508 may be caused to display the thumbnail of content corresponding to date information of the content.

Similarly, if a thumbnail of content displayed in the display screens 503 to 505 shown in FIG. 7 to FIG. 9 is selected, the thumbnail may be made to change to the display screen 508. If a thumbnail of content displayed in the display screen 506 or the display screen 507 displayed in calendar form is selected, the thumbnail may be made to change to the display screen 508.

Further, after the display screen 508 is displayed, the displayed date may be made to be changeable by pressing the right/left arrow keys, “<<” key, or “>>” key of a remote control or the like. Accordingly, the user can intuitively grasp content recorded in external devices or the like.

As shown in FIG. 13, the display apparatus 200 may be caused to display thumbnails of content by arranging thumbnails of the content clockwise in descending order of time associating with the clock display in which one turn corresponds to 12 hours. As shown in FIG. 13, by causing thumbnails of content to be displayed associating with the clock display in which one turn corresponds to 12 hours, the user can intuitively grasp in which time zone content is recorded. Further, by pressing an arrow key 5091 to change the time in units of 12 hours in the future or in the past, thumbnails of content in the display screen 509 can be changed to those of content corresponding to the changed dates/times.

In addition, by specifying only time zones in which thumbnails of a plurality of pieces of content are recorded, only thumbnails of content contained in the applicable time zones may be caused to be displayed. In the present embodiment, all recorded content is included for display, but the present invention is not limited to such an example. For example, only thumbnails of content in the genre specified by the user from all recorded content may be made to be displayed. Alternatively, only thumbnails of content recommended by a content provider may be made to be displayed.

[4] Operation of the Display Control Apparatus

In the foregoing, screen display examples have been described. Next, the display control method of the display control apparatus 100 will be described with reference to FIG. 14. FIG. 14 is a flow chart illustrating the display control method of the display control apparatus 100.

As shown in FIG. 14, the display control apparatus 100 first makes a search for external devices connected to the display control apparatus 100 (S102). Since, as described above, external devices such as a digital camera, digital video camera, and video recorder are connected to the display control apparatus 100, the display control apparatus 100 searches for external devices at step S102.

As a result of searching for connected external devices at step S102, it is determined whether there is any external device (S104). If it is determined at step S104 that there is a connected device, a contents list of content stored in the connected device is acquired (S106). Then, after returning to step S104, it is determined whether there is any other connected external device again.

If it is determined at step S104 that there is no other connected external device, all contents lists acquired at step S106 are collected (S108). After all contents lists being collected at step S108, the display control apparatus 100 holds all contents lists of content recorded in external devices connected to the display control apparatus 100.

Then, it is determined whether all contents lists have been collected (S110). If it is determined at step S110 that all contents lists are not collected, collection processing of contents lists at step S108 is performed again. If it is determined at step S110 that all contents lists are collected, a classification of contents lists is made by the classification unit 154 provided with the display control apparatus 100 (S112).

After the classification of contents lists being made at step S112, a timeline display is called (S114). The calling of timeline display at step S114 is to execute a call to cause the display screen displayed in the display apparatus 200 to display a timeline in chronological form or calendar form.

For example, the timeline display may be made to be selected from a menu screen in the display screen or by an operation key on a remote control. If the timeline display is called at step S114, a timeline is displayed in the display screen (S116).

The timeline display made at step S116 is to display thumbnails of content together with date/time information. That is, one of FIG. 5 to FIG. 13 is caused to be displayed. In the foregoing, the display control method of the display control apparatus 100 has been described.

According to the display control apparatus 100 in the present embodiment, the display apparatus 200 is caused to display thumbnails of a plurality of pieces of content by associating with a date/time display showing date/time information of a predetermined period for each piece of date/time information of thumbnails of the plurality of pieces of content and if one of displayed thumbnails of the plurality of pieces of content is selected, thumbnails of one piece or more than one pieces of content corresponding to date information of a thumbnail of one selected piece of content are arranged as thumbnails of content clockwise in descending order of time and displayed in the display apparatus 200. Accordingly, thumbnails of content are displayed together with date/time information and therefore, the user can intuitively grasp the presence of content of about what time.

If a plurality of external devices is connected to the display control apparatus 100, contents lists recorded in the plurality of external devices may be acquired to classify acquired contents lists according to each piece of date/time information of thumbnails of content contained in the contents lists. Accordingly, all contents lists recorded in the plurality of external devices can be collected and classified according to date or date/time so that content can be transparently grasped without being aware of in which external device the content is recorded.

The present application contains subject matter related to that disclosed in Japanese Priority Patent Application JP 2008-191836 filed in the Japan Patent Office on JP Jul. 25, 2008, the entire content of which is hereby incorporated by reference.

It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
