BACKGROUND SECTION
1. Field of the Invention
This invention relates generally to techniques for managing information, and relates more particularly to a system and method for accessing and utilizing ancillary data with an electronic camera device.
2. Description of the Background Art
Implementing efficient methods for accessing and utilizing information is a significant consideration for designers and manufacturers of contemporary electronic devices. However, effectively accessing and utilizing information by utilizing electronic devices may create substantial challenges for system designers. For example, enhanced demands for increased device functionality and performance may require more system processing power and require additional hardware resources. An increase in processing or hardware requirements may also result in a corresponding detrimental economic impact due to increased production costs and operational inefficiencies.
Furthermore, enhanced system capability to perform various advanced operations may provide additional benefits to a system user, but may also place increased demands on the control and management of various system components. For example, an enhanced electronic device that effectively captures, processes, and stores digital image data may benefit from an efficient implementation because of the large amount and complexity of the digital data involved.
Due to factors like the growing demands on system functionality, it is apparent that developing new techniques for accessing and utilizing information is a matter of concern for related electronic technologies. Therefore, for all the foregoing reasons, developing effective systems for accessing and utilizing information remains a significant consideration for designers, manufacturers, and users of contemporary electronic devices.
SUMMARY
In accordance with the present invention, a system and method are disclosed for accessing and utilizing ancillary data with an electronic camera device. Initially, in one embodiment, one or more ancillary data files may preferably be created by any appropriate entity and stored in a particular data source. For example, in one embodiment, a system user may create various ancillary data files on a discrete computer device for subsequent downloading and utilization by the camera device. Alternately, a manufacturer may create various ancillary data files, and make the ancillary data files available on a distributed computer network like the Internet for subsequent downloading and utilization by the camera device.
Next, the camera device may preferably establish an electronic communication path with the foregoing data source in any appropriate manner to thereby access one or more ancillary data files. The electronic communication path between the data source and the camera device may be established using any effective technique. For example, the camera device may access and download one or more ancillary data files using a removable non-volatile memory device, a hard-wired connection, or a wireless connection. Similarly, the camera device may access and download one or more ancillary data files from a either a stand-alone electronic device like a personal computer, or a distributed computer network like the Internet.
Then, the camera device may perform various on-line management procedures with the ancillary data files by means of the previously-established electronic communication path. The on-line management procedures may include any appropriate processes or functionalities. For example, a download manager from the ancillary data module of the camera device may advantageously select and download one or more of the ancillary data files from the data source. In certain embodiments, a system user may interactively view, manipulate, select, and download the ancillary data files from the data source.
After the download manager preferably downloads and locally stores one or more selected ancillary data files, the electronic communication path between the data source and the camera device may be terminated. Then, the ancillary data module may preferably analyze the downloaded ancillary data file(s), and coordinate any required off-line file management procedures, either automatically or through an interactive process involving a system user.
In certain embodiments, the ancillary data module may preferably analyze one or more descriptors corresponding to the downloaded ancillary data files to identify relevant information regarding the downloaded ancillary data files. A display manager may responsively update camera device menus for display in a camera viewfinder to thereby include any changes in the locally-stored ancillary data files.
Finally, a system user may advantageously utilize the downloaded ancillary data files in the camera device. For example, a system user may combine one or more downloaded ancillary data files in the camera device with corresponding captured image data to thereby produce a new composite image. In certain embodiments, a display manager may display one or more selected ancillary data files in the camera viewfinder while a system user positions and captures associated image data. In alternate embodiments, an editing module from the ancillary data module may allow a system user to view and edit a composite image of one or more selected ancillary data files and one or more selected captured images from data storage of the camera device. The present invention therefore provides an improved system and method for accessing and utilizing ancillary data with an electronic camera device.
