## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority from Korean Patent Application No. 10-2010-0087516, filed on Sep. 7, 2010 in the Korean Intellectual Property Office, the disclosure of which is incorporated in its entirety herein by reference.
BACKGROUND
1. Field
Apparatuses and methods consistent with the exemplary embodiments relate to a display apparatus and a displaying method of contents, and more particularly, to a display apparatus which is capable of classifying contents into groups and browsing the grouped contents, and a displaying method of contents.
2. Description of the Related Art
Display apparatuses use various methods to browse contents. Modern display apparatuses may browse contents based on geographical information such as a map. FIG. 1A shows using geographical information of contents (α1, α2, . . . , αN) to locate and browse the contents at positions on a map corresponding to the geographical information. However, since a TV does not have a pointing device which is similar to a pointing device in a PC, a user may not easily select contents to be reproduced on a TV if the number of contents (α1, α2, . . . , αN) is large. In addition, if there is a plurality of contents corresponding to the geographical information, it is inconvenient for a user to select desired contents since it is difficult to display all of the plurality of contents and a lot of contents information is provided at once.
FIG. 1B shows displaying contents (β1, . . . , β18) as thumbnail images. The display in FIG. 1B is inconvenient because, in order to check geographical information related to the contents (β1, . . . , β18), a separate screen has to be displayed which provides separate geographical information.
FIG. 1C shows contents (γ) and geographical information (δ) on which corresponding contents are located. The display in FIG. 1C is inconvenient since a plurality of contents (γ) corresponding to the geographical information can not be displayed simultaneously.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Below, exemplary embodiments will be described in detail with reference to accompanying drawings so as to be easily realized by a person having ordinary knowledge in the art. The exemplary embodiments may be embodied in various forms without being limited to the exemplary embodiments set forth herein. Descriptions of well-known parts are omitted for clarity, and like reference numerals refer to like elements throughout.
FIG. 2 is a control block diagram of a display apparatus according to an exemplary embodiment.
As shown, a display apparatus 1 includes a contents output unit 10, a user interface (UI) generating unit 20, a display unit 30, a user input unit 40 and a control unit 50 which controls these components. In this embodiment, the display apparatus 1 is implemented by an apparatus which classifies contents into groups using position information which corresponds to positions on predetermined space information, generates a UI indicating the groups, and displays the generated UI at the corresponding positions of the groups on the space information. For example, the display apparatus 1 may be implemented by a computer system, a television, various kinds of portable terminals, an electronic frame, a contents-contained camera, a camcorder or any other known in the art, all of which include a display unit.
The contents output unit 10 corresponds to an interface which is able to output various multimedia contents. The contents output unit 10 may include a contents storage (e.g., memory) which may store photographs, moving pictures, music files or various kinds of documents, or a connector to which a contents source, such as a camera, a MP3 player, a compact disc (CD)/Blue-ray disc (BD) or the like, may be connected, or any interface which may be connected to any network. For example, the contents output unit 10 may be implemented by a Bluetooth, an infrared communication and wired/wireless USB communication interface or the like. Alternatively, the contents output unit 10 may be implemented by an internal/external storage medium which stores contents such as photographs, moving pictures, music files, various kinds of documents and so on.
The contents include metadata which contain time information and/or space information. The control unit 50 may use the metadata to classify the contents.
Under control of the control unit 50, the UI generating unit 20 generates a first UI which displays groups to which at least one contents output from the contents output unit 10 belong. In addition, under control of the control unit 50, the UI generating unit 20 generates a second UI which displays sub groups into which contents contained in the groups are classified.
The generated first and second UIs may each include at least one of icons symbolizing the groups, the number of contents included in the groups, the kind of contents and thumbnail images of the contents. Examples of the icons may include numbers, characters, symbols, metaphors, pictograms and so on. Examples of the thumbnail images may include thumbnail images for still images, thumbnail images of albums for music files, main scene images for moving pictures and so on. If the contents are documents or various execution files, images related to the names of the contents may be included.
The display unit 30, under control of the control unit 50, displays predetermined space information and displays UIs indicating the groups into which the contents are classified at the corresponding positions on the space information.
The predetermined space information includes any form of information including geographical information, preferably a map. The predetermined space information includes a Maps API service (or Web map service) using a standard interface for sharing geographical information.
The predetermined space information may be zoomed in/out step by step at a plurality of levels. Accordingly, the space information of a certain region corresponding to each of the levels may be displayed on the display unit 30. The display apparatus may further include an image processing unit (not shown) which zooms the predetermined space information in or out on the display unit 30. The image processing unit (not shown) is controlled by the control unit 50. A UI 22 which allows the predetermined space information to be zoomed in/out step by step at a plurality of levels may be generated by the UI generating unit 20 under control of the control unit 50. Accordingly, if a zoomed in/out UI 22 is selected through the user input unit 40, the control unit 50 may control the image processing unit (not shown) so that the space information can be zoomed in/out to the selected level.
The display unit 30 may include a display panel (for example, a liquid crystal display (LCD) panel, an organic light emitting diode (OLED) panel or a plasma display panel (PDP)) and a panel driver which drives the display panel.
The user input unit 40 may receive a user selection such as a request to search for contents, contents selection and so on. The user input unit 40 delivers a preset signal corresponding to the reception of the user selection to the control unit 50 which then performs a control operation corresponding to the preset signal. To this end, the user input unit 40 may be implemented by menu keys (not shown) provided outside of the display apparatus 1, a remote controller (not shown), a touch pad (not shown) or the like. Alternatively, the user input unit 40 may be implemented by a touch screen (not shown) which may be incorporated into the display apparatus 1.
Upon receiving a request to search for contents from the user input unit 40, the control unit 50 may classify the at least one contents into at least one group based on predetermined position information of the at least one contents which corresponds to a position on the displayed predetermined space information, control the UI generating unit 20 to generate the first UI indicating the at least one group, and control the display unit 30 to display the generated first UI on the displayed predetermined space information at a corresponding position of the group. Hereinafter, browsing of the contents classified by the control unit 50 will be described in detail with reference to FIGS. 3 to 7.
FIG. 3 shows a first example of a contents classification and a display of the display apparatus according to an exemplary embodiment.
Upon receiving a request to search for contents from the user input unit 40, the control unit 50 classifies at least one contents, which are output from the contents output unit 10, into a preset number of groups based on predetermined space information 31 using the position information contained in the at least one contents.
The contents contain time information and position information as metadata. Accordingly, the control unit 50 may extract the position information from the metadata and use the extracted position information.
The control unit 50 may classify the at least one contents into the preset number of groups based on the predetermined space information 31. FIG. 3 shows one example where the predetermined space information 31 is represented by an image indicating a world map. Thus, when the space information is the image indicating the world map, the world map is partitioned into N areas using latitude and longitude, and contents having position information belonging to the N areas among the contents output from the contents output unit 10 are classified. In this case, N total groups are formed. The control unit 50 controls the UI generating unit 20 to generate UIs 21 indicating the formed N groups and controls the display unit 30 to locate and display the generated UIs 21 on the corresponding areas of the world map to which the groups belong. The generated UIs 21 may each include at least one of icons symbolizing the groups, the number of contents included in the groups, the kind of contents and thumbnail images of the contents.
In this embodiment, if the display apparatus 1 is a TV, for the purpose of facilitating a user's selection using a remote controller, the control unit 50 may partition the world map into 9 total areas using latitude and longitude and classify the contents output from the contents output unit 10 into 9 total groups. The control unit 50 controls the UI generating unit 20 to generate UIs indicating the 9 groups as numbers and controls the display unit 30 to locate and display the generated numbers at corresponding areas on the world map to which the groups belong. Thus, a user may easily select the groups using numerical keys of the remote controller so that the user can easily view the contents included in the groups.
FIG. 4 shows a second example of a contents classification and a display of the display apparatus according to an exemplary embodiment.
Predetermined space information 33 and a UI 22 for selection of a plurality of levels to zoom the space information in/out are displayed on the display unit 30.
Upon receiving a request to zoom-in/out the space information at a particular level of the zoom-in/out UI 22 through the user input unit 40, the control unit 50 controls the image processing unit (not shown) to zoom the predetermined space information in/out at the selected level. Accordingly, if the space information is zoomed in at a predetermined level through the zoom-in/out UI 22, an image indicating a particular area of the world map is zoomed in and displayed on the display unit 30 as space information 33, said particular area being smaller than the predetermined space information 31 shown in FIG. 3 which indicates the world map.
The control unit 50 partitions the zoomed-in particular space information 33 into M areas using latitude and longitude and classifies contents having position information belonging to the areas among the contents output from the contents output unit 10 into M total groups. The control unit 50 controls the UI generating unit 20 to generate UIs 23 indicating the M groups and controls the display unit 30 to locate and display the generated UIs 23 at the corresponding areas on the zoomed-in particular space information 33 to which the groups belong. As one example, the M groups may be formed to correspond to the number of character keys provided in the remote controller, and a user may easily select one of the M groups using the character keys of the remote controller so that the user can easily view the contents which belong to the selected group.
FIG. 5 shows a third example of a contents classification and a display of the display apparatus according to an exemplary embodiment.
Upon receiving a request to search for contents through the user input unit 40, the control unit 50 partitions the predetermined space information 31 being currently displayed into 4 total areas and classifies the contents output from the contents output unit 10 into 4 groups corresponding to the 4 areas. The control unit 50 controls the UI generating unit 20 to generate UIs 21a to 21d indicating the 4 groups. Here, the control unit 50 controls the UI generating unit 20 to generate the UIs 21a to 21d as numbers 1 to 4 and controls the display unit 30 to locate and display the generated UIs 21a to 21d at the corresponding areas on the space information to which the groups belong.
At this time, if Group 3 (21c) is selected through the user input unit 40, the control unit 50 zooms in on a map image, which corresponds to particular space information 35 to which Group 3 belongs, on the display unit 30, classifies the contents belonging to Group 3 into sub groups using the position information, and controls the UI generating unit 20 to generate a UI 23 indicating the sub groups on the display unit 30. At this time, the UI 23 indicating the sub groups is displayed with a different kind of icon from the UIs 21a to 21d indicating the groups. As one example, if the UIs 21a to 21d indicating the groups are displayed with numbers, the UI 23 indicating the sub groups may be displayed with characters or symbols.
At this time, the control unit 50 may cause UIs 21a, 21b and 21d indicating Group 1, Group 2 and Group 4, respectively, which are not selected by a user and have been already classified in the space information 31 before Group 3 is selected, to be displayed on the zoomed-in particular space information 35. At this time, the UIs 21a, 21b and 21d indicating Group 1, Group 2 and Group 4, respectively, may be displayed on edges of the zoomed-in particular space information 35. In addition, these UIs 21a, 21b and 21d may be displayed on edges of the zoomed-in particular space information 35 so as to maintain a positional relation with the UI 21c indicating Group 3. For example, in consideration of the positional relation with Group 3, the UIs 21a and 21b indicating Group 1 and Group 2, respectively, may be displayed on a left edge of the zoomed-in particular space information 35, while the UI 21d indicating Group 4 may be displayed on a bottom edge of the zoomed-in particular space information 35.
A user may select the UIs 21a, 21b and 21d indicating Group 1, Group 2 and Group 4, respectively, to jump to the contents included in Group 1, Group 2 and Group 3 without moving to the previous screen such as screen (A) of FIG. 5, so that the user can directly view the contents included in Group 1, Group 2 and Group 4.
This may provide easy transition between plural contents groups and hence increase a user's convenience.
In addition, if a UI 23a indicating one sub group in the UI 23 indicating the sub groups on the zoomed-in particular space information 35 is selected through the user input unit, contents included in the selected sub group may be classified and displayed based on time information 24. In this case, the contents are again classified into second sub groups by date (day, month, year) which may be displayed with thumbnail images (Thumbnail 1, . . . , Thumbnail 12). The user may easily select/move the second sub groups using directional keys of the remote controller.
FIG. 6B shows a fourth example of a contents classification and a display of the display apparatus according to an exemplary embodiment.
FIG. 6A shows a zoomed-in view of space information in a conventional display apparatus. The conventional display apparatus always zooms in on the space information step by step at a plurality of levels.
In FIG. 6A, (A) shows the space information zoomed in at Level 2, (B) shows the space information zoomed in at Level 3, and (C) shows the space information zoomed in at Level 4. The conventional display apparatus necessarily zooms in on the space information in the following order: Level 2, Level 3 and Level 4.
On the contrary, the display apparatus according to this embodiment may zoom in or out on space information while skipping at least one of a plurality of levels, as shown in FIG. 6B.
In this embodiment, contents are classified into a specific number of total groups (for example N total groups) in a predetermined space information zoomed in at a specific level (for example Level 2). Then, in response to an input requesting that the predetermined space information be zoomed in to a higher level (for example Level 3), it is determined whether there would be a change in the N groups at Level 3. If there is no change in the N groups at Level 3, then the space information is zoomed in to a higher level (for example Level 4) at which there is a change in the N groups while skipping Level 3. Then, the space information zoomed in at Level 4 may again be classified into M total groups. For example, it is considered that the predetermined space information 37 zoomed in at Level 2 is a map image indicating a territory of ‘Korea’, the predetermined space information zoomed in at Level 3 is a map image indicating cities, ‘Seoul’, ‘Suwon’ and ‘Incheon’ and the predetermined space information 39 zoomed in at Level 4 is a map image indicating community units, ‘Myungdong’ and ‘Kangnam’. If contents are classified into 3 groups at Level 2, contents are classified into the same 3 groups at Level 3 (having the same contents as classified into the 3 groups at Level 2), and contents are classified into 4 groups at Level 4 (having different contents than the contents classified into the 3 groups at Level 2). Accordingly, when the level of the space information is changed, the space information is zoomed in from Level 2 to Level 4 while skipping Level 3.
As shown, when the predetermined space information 37 zoomed in at Level 2 is displayed on the display unit 30, the control unit 50 partitions the space information 37 into 3 total areas, classifies the contents output from the contents output unit 10 into 3 groups corresponding to the 3 areas using the position information, and controls the UI generating unit 20 to generate UIs 25a, 25b and 25c indicating the 3 groups, respectively, at the corresponding positions on the space information.
If the UI 25a corresponding to Group 1 is selected through the user input unit 40 and it is determined based on the position information of the contents belonging to Group 1 that the level at which the space information in which the contents belonging to Group 1 can be again classified is at Level 4, the space information is directly zoomed in at Level 4 while skipping Level 3, the contents belonging to Group 1 are again classified into a plurality of sub groups using the position information based on the zoomed-in space information 39, and UIs 27a, . . . , 27d indicating the sub groups, respectively, are generated and displayed at the positions corresponding to the sub groups. Thus, the space information which can be displayed step by step at a plurality of levels based on the position information of contents can be zoomed in and displayed with at least one of the plurality of levels skipped. This may be equally applied to zooming-out.
FIG. 7 shows a fifth example of a contents classification and a display of the display apparatus according to an exemplary embodiment.
Upon receiving a request to search for contents from the user input unit 40, the control unit 50 may classify at least one contents which is output from the contents output unit 10 by date (day, month, year) using the time information of the contents. This may be applied to the first to fourth examples. Accordingly, the control unit 50 may classify the contents into the predetermined number of groups on the predetermined space information using the position information and again classify contents included in the groups into sub groups using the time information. At this time, the control unit 50 may control the display unit 30 to display the sub groups which have been classified based on the predetermined space information and the time information simultaneously. As shown, in response to a UI 29 indicating one of the groups classified based on predetermined space information 38 being selected and a request for searching the contents belonging to the selected group based on the time information being input through the user input unit 40, the contents belonging to the selected group may be classified and displayed by date (day, month, year) 26.
As another example, although it has been illustrated in the fifth example that contents are classified into N groups using the position information of the contents based on the predetermined space information, if a request to search all contents corresponding to the predetermined space information 38 based on the time information is input through the user input unit 40, the contents may be again classified into M groups by date (day, month, year).
FIG. 8 is a flow chart showing a control operation of the display apparatus according to an exemplary embodiment.
If a request to search for contents is input through the user input unit 40 (S11), the control unit classifies contents output from the contents output unit 10 into at least one group which corresponds to a position on predetermined space information using position information of the contents (S12), generates a UI indicating the group (S13), and causes the generated UI to be displayed at the corresponding on the space information (S14).
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the inventive concept, the scope of which is defined in the appended claims and their equivalents.
