The summary of the invention does not necessarily describe all necessary features of the present invention. The present invention may also be a sub-combination of the features described above. The above and other features-and advantages of the present invention will become more apparent from the following description of the embodiments taken in conjunction with the accompanying drawings.
The invention will now be described based on the preferred embodiments, which do not intend to limit the scope of the present invention, but exemplify the invention. All of the features and the combinations thereof described in the embodiment are not necessarily essential to the invention.
The image database 120 stores image data units. The image data acquiring unit 102 acquires a plurality of image data units and also acquires a plurality of units of attribute information of the respective image data units. The attribute information for each image data contains a created date at which the associated image data was created, a type of the associated image data and a captured position at which an image of the associated image data was captured. The image data acquiring unit 102 may receive the image data and the attribute information therefor from an image capturing unit for capturing an image, from a recording medium, or via a network. The image data acquiring unit 102 sends the image data units and the attribute information units therefor thus acquired to the attribute information acquiring unit 104.
The input unit 100 allows a user to input information regarding image data. For example, the input information is a title of the image data. The input unit 100 may receive a keyword as the input information. The input unit 100 sends the title thus input to the attribute information acquiring unit 104 as the attribute information. The attribute information acquiring unit 104 acquires the image data and the attribute information from the image data acquiring unit 102. The attribute information acquiring unit 104 receives the title of the image data from the input unit 100 as the attribute information. Then, the attribute information acquiring unit 104 sends the image data and the attribute information to the image data classifying unit 106 in such a manner that the attribute information is made to correspond to the associated image data. The image data classifying unit 106 sends the received image data to the image data analyzing unit 112.
The image data analyzing unit 112 analyzes the image data received from the image data classifying unit 106 to determine a scene of the image of the received image data, and then sends scene identifying information, indicating an identification of the scene as determined, to the image data classifying unit 106 in such a manner that the scene identifying information corresponds to the associated image data. More specifically, the image data analyzing unit 112 extracts image data created immediately before the image data received from the image data classifying unit 106, from the image database 120. The image data analyzing unit 112 analyzes the amount of change in color distribution between the extracted image data and the image data received from the image data classifying unit 106, so as to determine whether or not the scene in the received image data is the same as the scene in the extracted image data.
The image data classifying unit 106 classifies a plurality of units of image data into groups based on the attribute information received from the attribute information acquiring unit 104 and the scene identifying information received from the image data analyzing unit 112 for the respective image data unit. The image data classifying unit 106 stores, for each unit of the image data, group identifying information for identifying the group to which that image data belongs to and the attribute information for that image data, received from the attribute information acquiring unit 104, in the image database 120 so as to correspond to that image data. The image data classifying unit 106 also sends the group identifying information to the thumbnail image creating unit 108.
Then, the thumbnail image creating unit 108 extracts, from the image database 120, all the units of image data that are stored in the image database 120 so as to correspond to the group identifying information units received from the image data classifying unit 106. The thumbnail image creating unit 108 then creates thumbnail images for the extracted image data units and sends the created thumbnail images to the display unit 110. In a case where a plurality of units of image data were extracted, the thumbnail image creating unit 108 creates a thumbnail image for each extracted image data unit and sends it to the display unit 110. When receiving a plurality of thumbnail images, the display unit 110 creates an image to be presented in which the thumbnail images overlap each other. In another case where the display unit 110 receives only one thumbnail image, it uses the received thumbnail image as an image to be presented. The display unit 110 displays the image to be presented.
The input unit 100 allows the user to input an instruction indicating a certain thumbnail image is to be moved from the current group to another group. The input unit 100 changes the group identifying information associated with the image data corresponding to that thumbnail image, that is stored in the image database 120, based on the instruction thus input.
The group ID field stores scene identifying information for identifying a scene of an image of the associated image data. The image ID field stores an image ID for identifying the associated image data. The attribute information field stores attribute information for the image data.
The attribute information has a created date field, a type field, a title field and a location field. The created date field stores information indicating a created date at which the associated image data was created. In a case where the image data is a captured image, the created date field stores a captured date. The type field stores information indicating a type of the associated data, such as a data format. The title field stores information indicating a title of the image data. The location field stores information indicating a position at which the image data was captured, for example, GPS information. The image data field stores the image data.
In this way, the image managing apparatus 10 can classify the image data units based on the attribute information for each image data unit. The image managing apparatus 10 can also display a plurality of thumbnail images in such a manner that they overlap each other. Thus, the image managing apparatus 10 can provide an image to be presented that allows the user to easily view and manage the image data.
Then, the image data classifying unit 106 selects a group containing image data units, the number of which is equal to or larger than a predetermined number, for example, 10 (S202).
The image data classifying unit 106 then further classifies the image data units contained in the selected group based on the GPS information associated with the respective image data unit (S204). The image data classifying unit 106 classifies image data units having positions each shown by the associated GPS information, that are not within a predetermined distance, into different groups.
Then, the image data classifying unit 106 selects a group containing data units of 10 or more images (S206).
The image data classifying unit 106 further classifies the image data units contained in the selected group based on the titles associated with the respective image data units (S208). For example, in a case where image data units having titles of “Temple 1”, “Temple 2”, . . . and image data units having titles of “Beach 1”, “Beach 2”, . . . are included in the same group, the image data classifying unit 106 classifies the image data units “Temple 1”, “Temple 2”, . . . and the image data units “Beach 1”, “Beach 2”, . . . into different two groups.
Then, the image data classifying unit 106 selects a group containing 10 or more image data units (S210).
The image data classifying unit 106 further classifies the image data units contained in the selected group based on the information associated with the respective image data units, showing the types thereof (S212). For example, the image data classifying unit 106 classifies the image data units having different data formats into different groups.
The image data classifying unit 106 then selects a group containing 10 or more image data units (S214).
The image data analyzing unit 112 analyzes color distribution of the each image data unit contained in the selected group. More specifically, the image data analyzing unit 112 extracts a unit of image data included in the selected group and also extracts from the selected group another image data unit created immediately before the image data unit based on the information showing the created date. Then, the image data analyzing unit 112 analyzes the color distribution for each image data unit thus extracted, so as to determine that scenes of both the image data units are the same in a case where the change rate of the color distribution thus analyzed is equal to or smaller than a predetermined value (S216). Then, the image data classifying unit 106 classifies the image data units that were determined by the image data analyzing unit 112 to include the same scene, into the same group (S218).
On the other hand, in Steps S202, S206, S210, and S214, when the image data classifying unit 106 determines that no group contains 10 or more image data units, the image managing apparatus 10 finishes the operation in Step S104.
As described above, the image managing apparatus 10 can classify the image data units in a case where a group contains image data units, the number of which is equal to or larger than a predetermined number.
A floppy disk drive 712 reads data or a program from a floppy disk 714 and then provides the data or program to the CPU 700. A CD-ROM drive 716 reads data or a program from a CD-ROM 718 and then the read data or program to the CPU 700.
Software to be executed by the CPU 700 is provided to the user while being stored in a recording medium such as a floppy disk 714 or a CD-ROM 718.
