The present invention relates to graphical user interfaces in general, and in particular to graphical user interfaces adapted for browsing and retrieving pictures in picture databases.
Digital pictures and digital picture albums/collections are proliferating with recent advances in quality and cost reductions. Digital pictures can be stored in common or individual databases that allow a user to retrieve his or her pictures for viewing and reproduction via a computer system. The pictures can be stored as discrete files, or as linked files such as in a strip of film, for example. When a large number of pictures are stored in a collection, it is desirable to be able to browse and retrieve selected pictures with a graphical user interface (GUI). Used for such an application, a GUI conveniently organizes and groups database pictures, and allows a user to browse the pictures in one or more displays.
Along with the digital information representing pictures, digital image files can also contain metadata, or information not displayed, which nonetheless characterizes the data comprising the pictures. The metadata can describe the scene in the picture, such as a caption, and can also provide in a straightforward manner, information such as the date and time the picture was captured, the location from which the picture was captured, identify people or objects in the picture, and information regarding format and data structure.
Many prior art digital cameras can be programmed to automatically store along with the actual image, the date and time a picture was captured. More advanced digital cameras can also be programmed to automatically store along with the actual image, the location of picture capture by harnessing automatic location systems. For example, the Global Positioning Satellite (GPS) is a well-known method for pinpointing the location of a special GPS receiver with a fairly high degree of accuracy. Other methods include the use of Radio Triangulation (RT) systems. Using such an approach, a GPS receiver can be either incorporated in the hardware of the digital camera, or located nearby. A subsequent image file will contain not only the raw image data, but also a date and time stamp, along with header information related to the location of the GPS receiver when the image is collected.
Still more advanced digital cameras may contain pattern recognition software for identifying objects and people in an image, and converting such information to metadata.
Whether metadata is entered automatically by the camera, manually via the camera during picture captures, or subsequently into the digital image database, there remains a great need for improved GUIs for efficiently and attractively arranging pictures in a digital image database.
Many prior art methods for navigating picture databases still involve the use of Boolean word searches, which can be both awkward and unpleasant to view. Even when prior art GUIs are used for picture database navigation, it is desirable to browse an entire filmstrip without disregarding pictures that do not match search criteria. It is also desirable to search via icons representing pictures without having to type in search terms, and to have the ability to dynamically change a GUI display and search criteria with “drag and drop” operations.
To overcome the substantial deficiencies associated with prior art picture database navigation and retrieval operations, the method of the present invention at least includes the steps of providing a first display dimension representing a first characteristic of grouped pictures, providing a second display dimension representing a second characteristic of grouped pictures, providing a third display dimension representing a third characteristic of grouped pictures, and providing in the manner of a scatter plot, a plurality of picture icons plotted according to a first dimension along a first axis corresponding to the first display dimension, and a second dimension along a second axis corresponding to the second display dimension, each picture icon representing a group of pictures in a picture database. The third dimension is evidenced by distinct visual characteristics of the icons.
The present invention also provides a graphical user interface adapted to navigate and retrieve pictures in a picture database. The graphical user interface at least includes a first display dimension generator adapted to generate a first display dimension representing a first characteristic of grouped pictures, a second display dimension generator adapted to generate a second display dimension representing a second characteristic of grouped pictures, a third display dimension generator adapted to generate a third display dimension representing a third characteristic of grouped pictures, and an icon generator adapted to generate in the manner of a scatter plot, a plurality of picture icons plotted according to a first dimension along a first axis corresponding to the first display dimension, and a second dimension along a second axis corresponding the second display dimension, each picture icon representing a group of pictures in a picture database. The third dimension is evidenced by distinct visual characteristics of the icons.
Features and advantages of the present invention will become apparent to those skilled in the art from the description below, with reference to the following drawing figures, in which:
The graphical user interface (GUI) of the present invention novelly uses a dynamically linked, three-dimensional scatter plot for navigating and retrieving pictures in picture database, based upon picture metadata of pictures and picture filmstrips. The first two dimensions are displayed by locating icons (each representing a group of pictures) in two dimensions according to an ordered pair. The abscissa and ordinate pertain to two separate picture characteristics.
The third dimension of the three-dimensional scatter plot is a third picture characteristic. The value of the third dimension is indicated by the visual appearance of the plotted icons. In the preferred embodiment, the visual appearance and hence the third dimension is indicated by distinct colors which can be assigned to specific gradations of the third picture characteristic. However, other approaches to indicating the third dimension are possible, given the essence of the present invention, including unique shapes of the icon.
Referring to
The Who-What-When display 100 in
The icon 108 can represent a group of pictures in the database that contain a first identifiable person (e.g., Husband/Father of a family, or Wife/Mother), as part of a first identifiable event (e.g., New Year's Day), captured in the year 1999. As another example, the icon 116 might represent a group of pictures in the database containing the first-born daughter during a fourth identifiable event (e.g., Valentine's Day), captured during the year 2000.
The user can browse thumbnail representations of the pictures in a group by activating the icon (e.g., clicking a pointer while it is placed over the top of the icon).

In an alternate embodiment, the icons could be in the nature of spoked wheels, with the number of spokes indicating a different value of the third characteristic.
It will be appreciated by those skilled in the art, that many more combinations of “Who,” “What,” “When,” “Where,” and “Why” information can be used to generate scatter plots with the present-inventive GUI. It will also be appreciated by those skilled in the art, that other information categories based on metadata can be used to represent the three dimensions of a scatter plot, given the description of the present invention.
Given the disclosure of this Letters Patent, those skilled in the art will be able to implement a GUI which generates a three-dimensional scatter plot for more efficient and user-friendly browsing and retrieval of pictures stored in an image database. However, a general GUI system 500 for implementing the present invention is conceptually illustrated in FIG. 5.
The various components of the system 500 need not have physical proximity. Indeed, the system 500 can be self-contained in a stand-alone computer system, part of a Local Area Network (LAN), or part of a remote processing system using Wide Area Networks (WANs) such as the Internet, to name a few variations.
The system 500 includes a CPU 502 as do computer systems in general, a user interface 504 which allows a user to input commands and information (e.g., via a keyboard and mouse), and a display 506 for viewing the scatter plots, thumbnails, pictures, and other graphics, and a GUI generator 508 for generating dynamic scatter plots.
The GUI generator 508 generates the scatter plots representing pictures in the picture database loaded into a GUI memory 510. A GUI control 512 strips the metadata from the image files to determine the scatter plot to be generated, along with the value of the three dimensions. In response to the GUI control 512, a graphics generator 514 generates for display, the axes, icons and other graphics to produce the present-inventive, picture database three-dimensional scatter plots.
The present invention allows the user to specify exactly which picture characteristics to use for the scatter plots, and which dimension to correspond to a given picture characteristic. A change or update in one dimension automatically updates the other two picture dimensions.
Variations and modifications of the present invention are possible, given the above description. However, all variations and modifications which are obvious to those skilled in the art to which the present invention pertains are considered to be within the scope of the protection granted by this Letters Patent.
