     FIELD OF INVENTION 
       [0002]    The present invention relates to manipulating digital images over the Internet, and more particularly to providing an architecture for integrating photo-service-based websites for access by client devices. 
       BACKGROUND 
       [0003]    As the popularity of digital cameras grows, the desire of digital camera users to share their images with others will also continue to grow. The best approaches to photo-sharing take advantage of the Internet. Several Internet companies now offer an even more convenient approach by providing photo-sharing websites that allow users to store their images for free and to arrange the images into web-based photo albums. Once posted on a photo-sharing website, others may view the images over the Internet. 
         [0004]    The assignee of the present invention has developed a system for uploading images to the Internet, directly from the camera, as described in U.S. Pat. No. 6,636,259 entitled “Automatically Configuring A Web-Enabled Digital Camera To Access The Internet” issued Oct. 21, 2003. 
         [0005]    In this system, cameras connect to a gateway server on the Internet via a service provider, which may include a wireless carrier and/or an Internet service provider (ISP). In order to create a camera that requires no configuration to connect to the Internet, the camera is provided with a software application that is pre-configured to establish communication with the ISP and the gateway server. Upon establishing a connection, the camera sends the user&#39;s account ID and password to the gateway server. The user account information is then stored on the camera for use the next time the electronic device accesses the website. Thus, the user does not have to enter account information in order to establish the ISP connection or the website account before accessing the Internet. 
         [0006]    The gateway performs two basic services for the client. First, it is the camera&#39;s home base, which provides authentication services (user and device) and configuration services (it updates the camera&#39;s configuration, so the user doesn&#39;t have to). Second, it receives and responds to the camera application&#39;s requests using a protocol both understand. Services available to a camera may include the ability to send images from the camera to a specific photo-service service and the ability to send emails with links to uploaded images. 
         [0007]    The current gateway solution is built on traditional client-server architecture, where a software application on the camera communicates with a software application on the server. Client-server architecture requires custom software on all three tiers of the current architecture; the camera, the gateway, and the photo-service site. In addition, the current gateway solution only enables communication with digital cameras, not other mobile devices. 
         [0008]    A newer model for application deployment on the Internet today is server-based (i.e., ASP model), where a client device equipped with a web browser communicates with a web server. Browser-based devices simply download web pages from the server, which provides the application function and data. The deployment of web applications using this new server-based architecture is growing much faster than the deployment of client-server based applications because browser-based clients do not require a gateway that “speaks” the client application&#39;s protocol. Thus, browser-based clients may connect to the photo-service sites directly, since the devices are browser-based. In addition, browser-based clients also do not require embedded custom software for requesting imaging services from the photo-service sites. Instead, once connected, users of these devices could interact with the photo-services sites directly using the device&#39;s browser to display web applications from the photo-service sites if the sites support the specific browsers in these devices, or indirectly via a transcoding gateway. 
         [0009]    A transcoding gateway converts the sites&#39; HTML to a format suitable for the various browser types. Transcoding products exist today that can support multiple browser-based clients that are both wireless and wired. Transcoding technology takes a formatted input stream (typically HTML) from a web server and converts it to an output stream in another format (e.g., WML for WAP phones, cHTML for i-mode phones, etc) of a particular type of browser-based device. Digital cameras will soon be equipped with browsers, just as PDA&#39;s and cellphones are, and such transcoding products allow, or soon will allow, browser-based devices to access the images and image services of photo-services sites. 
         [0010]    There are two main problems with equipping digital cameras with web browsers for communication with photo-service sites and for running their web applications. One problem is making the presentation of the web applications palatable to the various types of browser-based devices, given the variety of display characteristics and browser technologies. There are two approaches to addressing this presentation problem. 
         [0011]    One approach is for each photo-service site to build custom web pages for each specific device/browser type. That is, the photo-service site would need to provide web pages formatted in HTML, WML, cHTML, and so on, and preprocess images to suit the device display capabilities. This is both labor intensive to initially setup and difficult to maintain as changes are made to the site&#39;s data and services. 
         [0012]    A second approach is to use a transcoding product, such as a WAP gateway or Oracle&#39;s Portal-to-Go. The problem with the transcoder approach is that it tries to solve a very broad problem, making all HTML encoded information presentable in a number of other different formats. Consequently, transcoders often produce unsatisfactory results. Transcoders thus serve as a temporary solution while photo-service sites build support for each of the various devices directly into their sites. 
         [0013]    As digital imaging grows in popularity, there will be a need for disparate photo-service sites to integrate their offerings (e.g., photo-hosting from one, and printing from another). This requires that two photo sites wishing to become partners must each enable their sites to communicate. Neither of the two approaches described above addresses the requirement of integrating the services that span the sites of multiple photo-service providers. Since there is no standard for inter-site communication for photo-service sites, this effort must be undertaken for each new partner a site agrees to work with. 
         [0014]    The second problem with equipping digital cameras with web browsers for displaying web applications from photo-service sites is the limitations inherent in web browsers, which is that browsers typically do not allow web applications to have access to content of the requesting device. Using a PC environment as an example, assume a user wants to upload images to a photo-sharing site on the Internet using a browser. To upload images, the user navigates to the photo sharing site and clicks an “upload” button. In response, the photo sharing site sends an upload web page to the user&#39;s PC. Because the web browser does not allow the upload web page to access to the hard drive, the upload page displays several blank image name fields for the user to fill-in. If the user does not know the names of the images, the user must click a “browse” button on the web page in order to search the directories on the PC for the desired image files. Once the user navigates to the correct directory and selects one of the images files, the name of the image file is then inserted into one of the image name fields on the web page. The process is then repeated for each image the user wants to have uploaded. 
         [0015]    Due to limitations imposed by web browsers on web applications with respect to the ability to access the internal storage of the requesting device, the process of manipulating images over the Internet via web browsers is burdensome and inefficient. 
         [0016]    Accordingly, what is needed is a method and system for integrating web photo-services for browser-enabled client devices. The present invention addresses such a need. 
       SUMMARY OF THE INVENTION 
       [0017]    The present invention provides a method and system for integrating web photo-services for a browser-enabled device. The method and system include providing a server that communicates with the device over a network, and associating images stored on at least one photo-service site with a user account. Thereafter, an inventory of images stored on the device is received from the device, and an image-related web application is provided to the device over the network, where the web application requires access to the user&#39;s images. The method and system further include providing a list of the images associated with a user&#39;s account to the web application, wherein the list of images includes an image reference for each image and an indication of whether each image is stored on the device or on the photo-service site, such that the web application may perform at least one function on the user&#39;s images regardless of where the images are stored. 
         [0018]    According to the present invention, the function of the web application is extended by allowing the web application to have access to references to the user&#39;s images, but not to the images themselves. Thus, the present invention overcomes the limitations imposed on the web application by the web browser and allows the web application to make intelligent decisions about what functions to perform on the user&#39;s images regardless of the images&#39; storage locations.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0023]    The present invention relates to an online digital imaging architecture. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. Thus, the present invention is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features described herein. 
         [0024]    The present invention provides a meta-application architecture for allowing photo-service websites to receive and send images to and from a wide range of client device types, and for integrating the services of the photo-service sites  14  for access by users of the client devices. The present invention also allows web applications running in a web browser on the client devices to access all of the user&#39;s image files regardless of whether the image files are stored on the client device or on sites on the Internet, thereby enhancing imaging services provided to the client devices. 
         [0025]      FIG. 1  is a block diagram illustrating a meta-application architecture for an online system  10  in accordance with a preferred embodiment of the present invention. The system  10  includes multiple client devices  12  that request imaging services from multiple online photo-service sites  14 . The photo-service sites  14  are sites on the Internet that provide different types of digital imaging services. For example, one photo-service site  14  may provide an image hosting service, while another photo-service site  14  provides image printing services, for instance. 
         [0026]    A client device  12  refers to an electronic device capable of capturing and/or displaying digital images and communicating over a network, such as the Internet. Such electronic devices include devices that store digital images, such as PCs and photo kiosks, and image capture devices such as digital cameras and PDAs, and cellphones that have lens attachments, for example. In a preferred embodiment, the client devices  12  are browser-based, although non-browser-based devices may also be supported. The client devices  12  communicate over the Internet via a wireless, or wired connection, but because they incorporate different browser types, the client devices  12  communicate data in different formats. For example, some client devices  12  such as PCs may communicate data in HTML format. Other client devices  12  such as cellphones, may use data formats such as Wireless Markup Language (WML), which is a streamlined version of HTML for small screen displays, cHTML which is a subset of HTML, and Handheld Device Markup Language (HDML), for instance. 
         [0027]    In one embodiment, the client devices  12  connect to the Internet via a service provider  16 , which may include a wireless carrier and/or an Internet service provider (ISP). Once connected to the Internet, the client devices  12  have the capability of uploading the digital images to the online photo-service sites  14  for storage and/or for receiving digital images from the photo-service sites  14  for display. 
         [0028]    One aspect of the present invention provides a meta-application  22  architecture that provides a common communication framework for integrating photo-service sites  14  and services for client devices  12 . The meta-application architecture includes a site on the Internet, referred to as the image gateway  18 , that interfaces between the client devices  12  and the photo-service sites  14 . In a preferred embodiment, the image gateway  18  includes a gateway server  20 , a software meta-application  22 , and a set of site adapter software  24  that provide a set of standard APIs and data formats that the photo-service sites  14  use so that the image gateway  18  can present data and services from the sites  14  to the various client devices  12 . These same APIs and data formats allow the image gateway  18  to present the services of multiple photo-services  14  in one integrated application, and allow communication among the photo-services sites  14 . For example, the image gateway  18  enables a user with images stored on one photo-host site to access to the services of all print service providers who also use the image gateway  18 . The photo-hosting site  14  would not need to make any special effort in order to work with the print service providers since they are all bound together by the meta-application. 
         [0029]    The gateway server  20  performs the function of a web server, while the meta-application  22  performs the function of an application server. The meta-application  22  may reside on the same or different computer from the gateway server  20 , and one of the photo-service sites may be part of the image gateway  18 . The gateway server  20  provides client device  12  connectivity and is primarily responsible for detecting the client device  12  type and its browser type and display characteristics. The gateway server  20  may also provide security, configuration, and administration services, including the collection of usage statistics. 
         [0030]    In a preferred embodiment, the gateway server  20  passes the data and service requests of the client devices  12  and from the meta-application  22  in a device independent fashion. 
         [0031]    One reason that there is no standard for communication between photo-service sites  14  is because each photo-service site  14  represents its own data and services in different formats. For example, all photo-hosting web sites  14  organize a user&#39;s images in a nested tree-like structure similar to a file directory, but the names of the nodes in these trees vary across sites. For instance, some of the terms used include “album,” “pholio,” “page,” and “shelves”. 
         [0032]    According to the present invention, the meta-application  22  abstracts the underlying data model and the function provided by the photo-service sites  14 , which is common across the photo-service sites  14 , to define a common data model format for the data, referred to here as a meta photo-service model. In a preferred embodiment, the meta photo-service model is implemented using XML. 
         [0033]    Since each photo-service site  14  may use its own data model and define its own API or protocol for accessing the site&#39;s functionality, respective site adapters  24  are used to convert between the data and service formats of each photo-service site  14  and the meta photo-service model  26 . 
         [0034]    In a preferred embodiment, the image gateway  18  is provided with a database  32  for supporting the aggregation of data and services across the various photo-service sites  14 . This enables the image gateway  18  to support a single login for a particular client device  12  and enables data sharing, such as billing information, across photo-service sites  14 . This data sharing eliminates the need for users to reenter this information for each site, but requires that the database  32  be synchronized with the data stored on the photo serving sites. 
         [0035]    According to a further aspect of the present invention, developers who have registered with the image gateway  18  may post web applications  42  on the image gateway  18  for access by the client devices  12 . In a preferred embodiment, the web applications  42  are imaging related and allow the users of the client devices  12  to manipulate their images in some manner. Examples of such imaging-related web applications  42  that may be provided include an upload image application that uploads images from the client device  12  to a photo-hosting service  14  via the image gateway  18 , and a search application that searches for the user&#39;s images, for instance. 
         [0036]    It should be noted that although the terms images as used herein includes media types such as still images, burst images, and time lapse images, the term images also encompasses media types such as movies, sound annotations, animations, and clip art, for instance. 
         [0037]    In a preferred environment, the web applications  42  are implemented as server-side processes that allow web pages to interact with databases and other applications. Examples of such server-side processes include active server pages (ASPs), CGI scripts and JavaServer Pages (JSPs), which are web pages that contains HTML and embedded programming code that is executed by a server. When a web browser makes a request from the web application  42  for a web page, the server executes the embedded program, and the HTML provides the page layout that will be returned to the web browser. The programming code provides the processing for the page, such as delivering search data entered on a web page to the database for lookup. It would also format the results of that search as HTML and send it back to the client device  12  for display. 
         [0038]    When a user attempts to work with his or her images on the browser-enabled client device  12  using one of the web applications  42 , the user&#39;s images may be stored in one of three ways; 1) on the client device  12 , 2) on one or more photo-service sites  14 , or 3) on both the client device  12  and one or more photo-service sites  14 . 
         [0039]    Displaying the user&#39;s images on the client device  12  using a conventional browser may be accomplished in one of two ways. First, the images stored locally on the client device  12  could be displayed by storing an HTML page that references those images in the device  12  and then opening the HTML page in the web browser. Second, the images that are stored on a web server could be displayed by the web server by sending an HTML page referencing those images to the web browser on the device  12 . Where the conventional browser fails is where the HTML page is being sent from the server to the device  12 , but the image files that need to be referenced are stored on the client device  12 . Thus, if the web application  42  needs to access images stored both in the device  12  and on the server, a problem arises because the browser on the client device  12  will typically not allow the web application  42  access to the contents of the client device  12 . In addition, the web application  42  would have no way of knowing about the user&#39;s images that are stored on other photo-service sites  14 . 
         [0040]    Besides providing a method for integrating web photo-services for a browser-enabled device, the present invention also allows a web application  42  sent from one server to know about files stored in locations other than that server. More specifically, the meta-application architecture of the present invention provides web applications  42  (under strict control and security) access to the user&#39;s images, which may be stored both locally on the client device  12  and distributed across photo-service sites  14 . 
         [0041]      FIGS. 2A and 2B  are a flow chart illustrating a process for allowing a web application  42  to access image files stored on both a client device and distributed across remote locations in a preferred embodiment of the present invention. The process begins by providing a gateway server  20  that communicates with the client device  12  and associates images from the client device  12  with a user account in step  100 . As described above, the user&#39;s previously uploaded images may be distributed across various photo-service sites  14 . 
         [0042]    The client device  12  is also provided with software that is capable of reporting the image contents of the device to the gateway server  20  in step  102 . The software may report the image contents of the device either automatically, or at the request of the user or the image gateway  18 . In a preferred enlightenment of the present invention, the software that reports the image contents to the gateway server  20  is a customized web browser. In an alternative embodiment, the underlying software in the client device  12  that establishes the connection to the gateway server  20  is responsible for reporting the images in the client device  12  to the gateway server  20 . In the second embodiment, the browser itself need not know about the images directly, but only through references provided via downloaded pages from the gateway server  20 . 
         [0043]    Once communication between the client device  12  and the image gateway  18  has been established, the client device displays a web page from the gateway server  20  indicating what web applications  42  are available to user in step  104 . In a preferred environment, the available web applications  42  are displayed via hyperlinks. For example, the web page displayed to the user may display links such as “Upload Images,” and “Search For Images,” which link to corresponding web applications  42 . 
         [0044]    In response to the user selecting a web application, the gateway server  20  connects the client device with the selected web application  42  in step  106 . Those with ordinary skill in the art will appreciate that the connection is preferably established with a secure handshake mechanism. 
         [0045]    When the web browser in the client device  12  begins interacting with the web application  42 , the web application  42  sends a request to the gateway server  20  asking what images are available for the user in step  108 . In a preferred embodiment, the web application  42  identifies the user to the gateway server  20  using the user account or user ID, which was provided to the web application  42  when the connection was made to the application  42  by the gateway server  20 . In response, the gateway server  20  prepares and returns a list of image references and other information corresponding to the user&#39;s images in step  110 . 
         [0046]      FIG. 3  is a diagram illustrating an example image list  50  sent from the gateway server  20  to the selected web application  42  interacting with the browser  54  on the client device  12  through the gateway server  20 . In a preferred embodiment, the image references in the list  50  comprise image identifiers (IDs)  56  that uniquely identify each image. The image IDs  56  may comprise a number or a name, or an internal disk reference (e.g., file path). The information included in the list may include the location  58  of each image (e.g., the device or a server), and may even include information about which server. The information may also include metadata  60  corresponding to each image. The metadata  60  is data associated with an image that is either embedded within the image file or separately in a file or database. Examples of metadata  60  include values for parameters such as f-stop, zoom factor, focus distance, category tags, image name, camera manufacturer and model number, and so on. Specific metadata may be requested by the web application to be included in the list, including custom user metadata. 
         [0047]    According to the present invention, the web application  42  interacting with the browser on the client device  12  is not given access directly to the user&#39;s images, instead the web application  42  is only given access to information about the images via the image list  50 . The information in the list  50  returned to the web application  42  is sufficient to allow the web application  42  to sort and select the images to carry out its function. 
         [0048]    Referring again to  FIGS. 2A and 2B , after receiving the image list  50 , the web application  42  selects a set of images to reference for display and/or to perform a function on in step  112 . As shown in  FIG. 3 , the web application  42  places these references in web pages that are returned to the device browser  54  through the gateway server  20 . 
         [0049]    Referring again to  FIG. 2B , for images that are identified in the list  50  as being stored locally on the client device  12  in step  114 , the web application  42  generates a reference that comprises a file path or other pointer to the image in the client device  12  along with a resize command in step  116 . Preferably, this translation from image ID to the file path is performed by the gateway server  20  when the web page containing the ID passes through on its way from the web application  42  to the client device  12 . 
         [0050]    For images that are identified in the list  50  as being stored on a photo-service site  14  or other server in step  118 , the web application  42  makes a request for the image from the gateway server  20  using the image ID in step  120 . The gateway server  20  then fetches the image from the indicated location, resizes and converts the image to the required format, and passes a URL to the resulting resized image file back to the web application  42  in step  122 . The web application  42  then inserts this URL into to the web page that is transmitted to the device browser  54  in step  124 . Alternatively, the translation from image ID to a URL to a resized, converted image file is performed at the gateway server  20  when the web page containing the ID passes through on its way from the web application  42  to the client  12 . For image viewing, there is no actual requirement for the web application  42  to have a copy of the image or images being displayed on the client device  12 . 
         [0051]    The entire viewing function can be done with image references, along with appropriate gateway functions and browser requests for local files. However, when a web application  42  wishes to perform an operation on an image, such as color balance, contrast enhancement, rotate, etc., an actual copy of the image is required at the web application  42 . Thus, the web application can request a copy of the image from the gateway server  20  in any resolution up to full image resolution. In this case, the web application  42  will perform whatever function desired, and create any versions of the image, such as thumbnails, within its own file system for reference by the browser  54 . The modified images can be temporary or permanent. For permanent images, the web application  42  must request that the gateway server  20  store the resulting image in an appropriate location, depending on the user&#39;s account information. 
         [0052]    The web application  42  may also need to delete images selected by the user. For example, if a modification is performed, and the user wants to keep the modification and not the original, a delete function is required. If images are uploaded from the client device  12  to a photo hosting/sharing service, the user may wish the copies in the device  12  be deleted, thus eliminating duplicate storage. However, allowing the web application  42  to delete images is a dangerous practice. It is assumed that all destructive operations are carried out over secure connections to prevent unauthorized access, but even with this protection, additional security protection is required. 
         [0053]    The preferred embodiment is for the delete function to be handled by the gateway server  20 . In this case, any image delete functions must be requested by the web application  42 . The gateway server  20  would be responsible for issuing the appropriate warning to the user via the browser  54  or its underlying software. Additionally, the gateway server  20  may cache copies of all deleted files for a period of time or until the user “empties the trash,” thus preventing the user from accidentally destroying valuable images. This is especially true for deletes of original images when image modifications are done. It is good practice to never delete the original image, and carry modifications via additional files. 
         [0054]    The present invention will now be explained by way of a particular example where the web application  42  provides an image upload function for the user of the browser-enabled client device  12 . 
         [0055]      FIG. 4  is a flow chart illustrating the process of uploading images from a web-enabled client device  12  using a web application  42  that is accessed through the image gateway  20  in accordance with a preferred embodiment of the present invention. During normal operation of the client device  12 , the user may be shown a homepage of the image gateway  20 , which displays a selection of image-related functions the user may want to use in step  200 . In response to user selecting the choice to upload images to a photo-service site  14 , the gateway server  20  connects the client device  12  to a corresponding upload web application  42  in step  202 . The gateway server also provides the upload web application  42  with the image list  50  identifying the user&#39;s images in step  204 . As described above, the image list  50  will identify both images present in the client device  12  as well as images stored on the client device and the image gateway  18  and other photo service sites  14 . 
         [0056]    The upload web application  42  will then automatically select images stored on the client device from the image list  50  and present corresponding thumbnail images to the client browser via HTML tags in step  206 . In a preferred environment, the HTML tags incorporate the image IDs and/or file paths from the image list  50  and may also include height and width tags for resizing the original image into the thumbnail image. 
         [0057]    The browser  54  on the client device  12  then interprets the HTML and renders the images presented by the web application  42  (resizing the original images if necessary) in step  208 . Since the images are local, no web traffic is required to service the image tags—they are accessed locally and resized locally. The web applications  52  allows the user to select which of the displayed images to upload in step  210 . In response, the web application  42  uploads the selected images to the gateway server  20  in step  212 , where they are then transmitted on to the selected photo-service site  14   
         [0058]    After successful completion of the upload, the web application  42  may ask the user if the device resident copies of the uploaded images should be deleted. If the user selects YES, a request for deletion is issued by the web application  42  to the gateway sever  20 . The gateway server  20  performs the appropriate deletion function, typically including getting confirmation from the user before proceeding. The confirmation may come from the gateway server  20 , or may come from underlying software in the client device  20 , which is designed to intercept any delete requests from the browser or internet connection. 
         [0059]    As a further example, assume that a developer provides a search web application  42 , which when run on the browser  54  of the client device  12  allows the user to enter search criteria, and in response, the search web application  42  returns and displays a set of images meeting those criteria. In operation, the gateway server  20  would provide the web application  42  with a list  50  of the user&#39;s images. As described above, the image list  50  would include for each image an image ID  56 , the location  58  of the image, and any metadata  60  associated with the image. The metadata  60  could be specifically requested, based on the user criteria. The web application  42  would then use this information to find the images matching the user&#39;s search criteria. For the found images that are stored in locations other than the client device  12 , the web application  42  would request that the gateway server  20  fetch, resize, and convert these images for access by the browser  54  in the client device  12 . The web application  42  would thus combine the images found on the client device  12  with the images transmitted from the gateway server  20  and display them to the user through the browser  54 . 
         [0060]    According to the present invention, the meta-application architecture provides a service that extends the functionality of web applications  52  that function through the browser on the client device. Image-related web applications  52  can now operate on all of a user&#39;s images without regard to where the images are stored and can make intelligent services available to the user. The intelligence for handling where the images are located and what to do with the images to make them display in the client device  12  is performed by the image gateway  18  for the web application  42 . Since most photo-service sites  14  today do not have the ability to interact directly over the Internet with client devices  12 , the present invention provides a service that allows an interface designed for the LCD screen of the client device  12  to access the photo-service sites  14  that don&#39;t have that capability, and brings all the user&#39;s images under one service and one access point. 
         [0061]    Although the present invention has been described in accordance with the embodiments shown, one of ordinary skill in the art will readily recognize that there could be variations to the embodiments and those variations would be within the spirit and scope of the present invention. Accordingly, many modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims.
