    • 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.

    • 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).

    • 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.

    • A portable computing device or “information appliance” having terse user input (e.g., limit set of keys) is provided with an improved user interface. A six-key embodiment is described that provides a “super-key” light entry and editing input system for ultra-portable devices, thus making it well suited for use with credit card-sized devices. In a preferred six-button embodiment, a credit card-sized device is modified to include an additional input button, an EDIT key. In user operation, pressing the EDIT key brings up a context sensitive pop-up menu, thus invoking the super-key feature. Customized user input controls, such as a Text Input Control (e.g., letter and number strips), are provided at appropriate times, for facilitating input. Underlying the super-key input is a heuristic sub-system that remembers and anticipates user input. In this fashion, the system can present in-context options for each application running on the target device, and present appropriate options during different phases of the execution of a variety of tasks. By remembering what the user has previously inputted and by using context-sensitive menus and adaptive “quick” lists, the system can anticipate what the user needs to do at any given time and can guide the user through a step-by-step process to complete each task, thus facilitating the tasks that users most often perform. By including adaptive techniques or built-in intelligence that allows the device to be faster and easier to use with each user session, the target device may anticipate the tasks users need to perform in specific situations and thus make those tasks increasingly easier.
