摘要:
A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

摘要:
A digital imaging system is described that provides techniques for reducing the amount of processing power required by a given digital camera device and for reducing the bandwidth required for transmitting image information to a target platform. The system defers and/or distributes the processing between the digital imager (i.e., digital camera itself) and the target platform that the digital imager will ultimately be connected to. In this manner, the system is able to decrease the actual computation that occurs at the digital imager. Instead, the system only performs a partial computation at the digital imager device and completes the computation somewhere else, such as at a target computing device (e.g., desktop computer) where time and size are not an issue (relative to the imager). By deferring resource-intensive computations, the present invention substantially reduces the processor requirements and concomitant battery requirements for digital cameras. Further, by adopting an image strategy optimized for compression (compressed luminosity record), the present invention decreases the bandwidth requirements for transmitting images, thereby facilitating the wireless transmission of digital camera images.

摘要:
A digital imaging system is described that provides techniques for reducing the amount of processing power required by a given digital camera device and for reducing the bandwidth required for transmitting image information to a target platform. The system defers and/or distributes the processing between the digital imager (i.e., digital camera itself) and the target platform that the digital imager will ultimately be connected to. The system only performs a partial computation at the digital imager device and completes the computation somewhere else, such as at a target computing device (e.g., desktop computer) where time and size are not an issue (relative to the imager). This image processing technique employs an efficient color conversion process, using a GUV color space. After an RGB mosaic (image) is captured, the image may be “companded” or quantized by representing it with less bits (e.g., companding from 10 bits to 8 bits). The image is then mapped from RGB color space to GUV color space, using an RGB-to-GUV transformation. Once converted into GUV color space, the image may now be compressed, for instance using wavelet transform-based compression, and then transmitted, using wireless or wire-line transfer, to a target platform (e.g., desktop or server computer). At the target platform, the GUV information may be restored in a non-compressed format and then further processed into a desired representation (e.g., standard format, such as JPEG). In this fashion, the GUV-based methodology avoids the inefficiency of remaining in RGB color space and avoids the computational complexity of converting to YUV color space, yet retains the benefits associated with YUV color space (e.g., de-correlation of image information).

A synchronization system providing multi-client synchronization is described. By storing the data that is actually being synchronized (i.e., storing the actual physical body of a memo, for instance) inside an extra database, “Grand Unification Database” (GUD), (or by specially-designated client data set) under control of a central or core synchronization engine, rather than transferring such data on a point-to-point basis, the system of the present invention provides a repository of information that is available at all times and does not require that any other synchronization client (e.g., PIM client or hand-held device) be connected. The GUD provides a super-set of the other client data sets. Therefore, if the user now includes an additional client, such as a server computer storing user information, the synchronization system has all the information necessary for synchronizing the new client, regardless of whether any of the other clients are currently available. The system can, therefore, correctly propagate information to any appropriate client without having to “go back” to (i.e., connect to) the original client from which that data originated.

An enhanced “Camel-back” or “Companion” Digital Organizer (CDO) is described that is designed to interface to a cellular telephone. The CDO is preferably implemented as an add-on component which can be easily attached and detached from a phone by a user and, once in place, can dramatically enhance the phone's functionality by converting the phone into a “smart” phone. Exemplary features of the CDO include an ability for the user to initiate a voice call on the phone from the CDO. Preferably, the user may initiate the voice call from any of multiple modules of the user's data, and not merely from a phone-book module. The CDO is also capable of stand-alone use as a personal organizer device, apart from the phone. The CDO preferably includes a docking unit that removably mates to particular model(s) of phones, and a main unit that removably docks to the docking unit. The docking unit preferably includes substantially all phone-model-specific geometries and features to thereby allow the main unit to be configured for stand-alone use as an organizer with few compromises made to accommodate specific model(s) of phones. Furthermore, the same main unit is suitable for use with multiple docking units that are respectively adapted for different models of phones. Note that some phones have an “automatic hang-up” feature in which the phone unilaterally hangs up a phone call that was initiated by an external device (e.g., a modem or the CDO) upon detaching of the device by the user. For such phones, the docking unit remains attached to the phone during a call initiated by the user via the CDO, even if the user should detach the main unit for stand-alone use as an organizer. The still-attached docking unit contains sufficient circuitry and physical features to prevent automatic hang-up. The main unit includes many features such as a choice of both left- and right-handed modes and the capability for handling electronic mail, remote browsing, remote synchronization, caller identification, and the like.

An imaging system is described that automates fulfillment of image photofinishing based on location. The system includes the following components: an imaging device capable of capturing a plurality of images; a local host, at least occasionally connected to the imaging device, that is capable of offloading images from the imaging device and capable of determining a current position based on GPS (Global Positioning System) information; and a remote (e.g., Web-based) host capable of receiving the plurality of images, capable of receiving a request for photofinishing the images, and capable of transmitting the plurality of images to a particular fulfiller for photofinishing, based on the current position.
