     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to the field of digital capturing and, more particularly, relates to a user interface for a portable hand-held capturing and communicating appliance for capturing and manipulating images through digital scanning or other means of capturing and communicating those images to other devices. 
     2. Related Art 
     Intangible information is a vital business asset that can be exploited for competitive advantage if managed properly. In the past fifteen years, improvements in information processing have been achieved primarily from the widespread use of microcomputers in the workplace and their application in local and wide area networks. Through such applications as electronic mail (email) and networked access to document storage servers, the electronic communications market has exploded. Nevertheless, business is still far from reaching a “paperless” workplace. For example, according to a 1993 report by BIS Strategic Decisions (hereinafter BIS), an information technology consulting firm, more than 90 billion documents were created in 1992 and more than 1 trillion copies of those documents were made. Moreover, BIS estimated that printing and copying expenses average between 6% and 13% of a typical company&#39;s revenue. These statistics illustrate the economic savings available for those businesses that are able to merge paper and technology in a unified information processing strategy. 
     One tool that has proven useful for translating between paper and electronic information is the digital scanner. Scanner-enabled document distribution endows paper-based documents with the speed and convenience of electronic communications. A desktop scanner or network scanner allows business professionals to scan paper-based documents, manage them effectively and distribute them in a timely fashion. Users can share and distribute information easily by scanning directly to their email or PC fax applications. The growing popularity of fax modems and email is driving the acceptance of scanner-enabled document distribution in offices of all sizes. Fax/modem capabilities, which are available with virtually all modem PCs, enable users to send and receive faxes directly from a computer—at their desk or while traveling—and to check email remotely. 
     Nevertheless, while scanners are ideal for users who need to disseminate paper-based information to colleagues through PC facsimile and/or email, traditional flatbed scanners lack the convenience and flexibility that users have become accustomed to through such products as notebook computers and cellular phones. Hand-held scanners are an improvement in this regard; however, they are typically dependent on a host computer for displaying the scanned images and for providing power. U.S. Pat. No. 5,550,938 to Hayakawa et al. (hereinafter Hayakawa) discloses a portable image scanner designed to overcome these disadvantages. Specifically, Hayakawa discloses a hand-held cordless image scanner having a display/control screen, a memory for storing scanned images, a self contained power supply and an interface that allows the scanner to be received by a host computer as a memory card for transferring stored images from the scanner to the computer. While Hayakawa&#39;s scanner is effective in breaking the dependency on a host computer for image display and power, it still has several drawbacks. For example, Hayakawa&#39;s scanner offers no image processing features other than the capabilities of storing or discarding a newly scanned image and reviewing those images that have been stored previously. More advanced image processing would necessarily be done after transfer to a host computer. Moreover, Hayakawa does not offer a graphical user interface (GUI) containing icons and/or animations to assist users in operating their device. Finally, transfer of images is limited to those devices having ports for receiving an external memory card or the capability of reading the scanner memory through a memory card drive. 
     Accordingly, a heretofore unaddressed need exists in the industry for providing a hand-held image capturing device, system and method that allows users to view, manipulate and process scanned images in the device before transfer, and the ability to communicate directly with some other unit such as a computer, printer, or facsimile machine. In addition, the capturing device should provide cordless operation and use a standard interface for transferring images to other devices. A GUI is preferred to assist users, particularly novices, in operating the device. 
     SUMMARY OF THE INVENTION 
     The present invention overcomes the inadequacies and deficiencies of the prior art as discussed hereinbefore. The present invention provides an image capturing appliance incorporating a viewing system and method for communicating with and allowing the user to view captured images on the appliance. The viewing system and method facilitate ease of use and hardware simplification and miniaturization of the capturing appliance for seamless integration of the appliance into a consumer&#39;s existing tools and processes.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Reference is now made to the drawings wherein like reference numerals designate corresponding parts throughout these several figures. It should be understood by those skilled in the art that some aspects of the present invention may be practiced on any apparatus for the purpose of viewing an image and is not limited to apparatuses which include or do not include image capturing capabilities through a photoelement array or scanning. For example, a user may use the present invention for viewing pages on the World Wide Web (WWW) or other network using some communication device. 
     Architecture of the Image Capture and Communication Appliance 
     A portable, hand-held, image capture and communication appliance  22  embodying the principles of the present invention is shown in FIGS. 1A through 1D. Specifically, FIG. 1A depicts one side (i.e., front) of appliance  22  where a flat-panel display  24  along with user operation buttons  26 ,  28 ,  32 ,  34 ,  36 ,  38  and user navigation buttons  42 ,  44 ,  46 ,  48  are located. Display  24  is preferably of the flat-panel variety to accommodate the hand size dimensions of appliance  22 . Common types of flat-panel displays suitable for use in the present invention include electroluminescent displays, gas plasma discharge displays, liquid crystal displays (LCDs) and field emission displays (FEDs). Display  24  is the means by which information, including captured images, text, icons, and animations, is communicated to the user. The user operation buttons comprise an image send or transmit button  26 , an image zoom button  28 , an image rotate button  32 , an image delete button  34 , a help utility button  36  and a tools menu button  38 . Send, zoom, rotate, and delete buttons  26 ,  28 ,  32  and  34  allow the user to electronically manipulate an image or page that has been scanned into memory through photoelement array  52 . Activation of tools button  38  presents the user with a menu that includes possible image operations (e.g., image attachment/grouping, image detachment/ungrouping), changing the mode of appliance  22  (i.e., toggling between text (binary) capture and image (grayscale) capture), calibrating appliance  22 , displaying a screen identifying important specifications such as a model number, hardware or software release number, memory usage, selecting a page size for printing, etc., or other user utilities not deserving of a dedicated external button for activation. Help button  36  provides the user with access to general tutorials, process animation, and how-to instructions on the operation of appliance  22  and context sensitive instruction when requested while another operation or menu is active. The navigation buttons include an up button  42 , a down button  44 , a left button  46 , and a right button  48  and are controlled by the user to steer a course through menu items and to view images or pages that have been captured in memory. FIG. 1B shows the side of appliance  22  opposite that illustrated in FIG. 1A (i.e., back). The back side of appliance  22  includes image capture button  54 , which is depressed by a user to scan an image through photoelement array  52  and is released once the image is captured. A power switch  56  is included at one end of appliance  22  as shown in FIG. 1C and a contrast control  58  for display  24  is located at the other end of appliance  22  as shown in FIG.  1 D. The positioning of the various buttons, power switch  56  and contrast control  58  on appliance  22  as shown in FIGS. 1A through 1D is merely exemplary and can be modified as needed to satisfy the ergonomic requirements of the targeted user community. 
     Referring now to FIG. 2, the internal architecture of appliance  22  will be described hereafter. Appliance  22  includes a processor  62 , which communicates with a memory  64  via address/data bus  66 . Processor  62  can be any commercially available or custom microprocessor suitable for an embedded application. Memory  64  is representative of the overall hierarchy of memory devices containing the software and data used to implement the functionality of appliance  22 . Memory  64  can include, but is not limited to, the following types of devices: cache, ROM, PROM, EPROM, EEPROM, flash, SRAM, and DRAM. As shown in FIG. 2, memory  64  holds four major categories of software and data used in appliance  22 : the operating system  68 ; the application software  70 ; the I/O device drivers  72 ; and the image data  74  generated for each scan. Operating system  68  should be designed for real time embedded applications and, preferably, is relatively compact to make the most efficient use of memory  64 . One such example of a real time operating system meeting these criteria is the PSOSYSTEM operating system (pSOSystem® or pSOS®) sold by Integrated Systems, Inc., Santa Clara, Calif., U.S.A., which is used in the preferred embodiment of the present invention. I/O device drivers  72  include software routines accessed through operating system  66  by application software  70  to communicate with devices such as display  24 , certain memory components  64  and I/O ports such as a serial port or infra red (IR) port for transferring data to another appliance, device or system. The digital representations of the images captured by appliance  22  is denoted by image data  74 . The format used for storing the images should be compatible with application software  70 . One common format used for encoding images is the JPEG standard; however, other public or proprietary standards can be used with equal success. In the preferred embodiment, CCITT-G4, which is designed for facsimile usage and black and white images, is used. Finally, application software  70  comprises the control programs that implement the various features of appliance  22 . Application software  70  and devices drivers  72  are typically written in a high-level programming language such as C or C++ for development convenience. Nevertheless, some drivers or application modules are sometimes written in assembly or machine language to optimize speed, memory usage or layout of the software in memory. In the preferred embodiment, the present invention uses C language to implement most application software  70  and device drivers  72  and assembly language for the most time-critical sections. 
     Application software  70  can be broken into several modules corresponding to the various features of appliance  22 , as shown in FIG.  2 . These software modules include an initialization module  76 , a capture page module  78 , a thumbnail view module  82 , a zoom view module  84 , a page rotation module  86 , an attach page module  88 , a detach page module  92 , a delete page module  94 , a send page module  96 , an error utility module  98 , a help utility module  102  and a menu/navigation interface module  104 . Note that an image captured in memory is interchangeably referred to herein as a “page” because the image is portrayed in appliance  22  as a physical page of text and/or imagery. A brief overview of each of the aforementioned modules follows hereafter. 
     Initialization module  76  contains the boot software that is invoked when appliance  22  powers up. This module works closely with operating system  68  and device drivers  72  to perform any hardware initialization for processor  62 , memory devices  64 , display  24 , and software initialization for global resources, such as message queues and buffers, system tasks, and memory partitions. Capture page module  78  controls the acquisition of images through photoelement array  52  and their conversion into a suitable format for storage in memory  64 . Thumbnail view module  82  provides the default visual for pages and icons shown on display  24 . The thumbnail view presents an entire page on display  24  as illustrated in FIG.  8 C. Zoom view module  84  allows the user to magnify a portion of a page as illustrated in FIG.  8 D. The operation of the zoom view module  84  will be discussed in detail hereinafter. Page rotation module  86  allows the user to rotate a page either in thumbnail or zoom view in 90° increments. Attach page module  88  allows the user to logically join pages together to form a group of pages that can be deleted, sent or viewed as an individual unit, but not rotated or zoomed. Rotation and zoom always apply only to the current page. Conversely, detach page module  92  allows the user to separate a page or pages from a previously formed group. Send page module  96  allows the user to transfer a page or group of pages to another appliance, device or system through the serial or IR communication ports of appliance  22 . Error utility module  98  provides notification to the user when the user attempts an invalid operation. Help utility module  102  provides the user, in real time, with general instructions and animations on operating appliance  22  and context sensitive instructions for performing a specific operation. Lastly, menu/navigation interface module  104  provides the user with graphical menus for performing various operations and processes the user&#39;s response thereto. Moreover, menu/navigation interface module  104  responds to navigation buttons  42 ,  44 ,  46 , and  48  that allow the user to steer a course through the graphical menus and view the stored pages. 
     A high level state diagram for application software  70  is shown in FIG.  3 . This state diagram is useful for gaining a broad understanding of the operation of application software  70  and its associated software modules. These states are representative of tasks or processes in application software  70  that act on messages from a message queue, which are generated as a result of user interaction with appliance  22  (i.e., activation of buttons). Appliance  22  and application software  70  begin and terminate from the off state  106 , which is controlled by the user through operation of power switch  56 . Off state  106  can clearly be entered from any other state in response to a user turning appliance  22  off through switch  56 . When a user turns switch  56  to the on position, the system will pass through a transient initialization state  108  during which time initialization module  76  is invoked to perform its functions. Once system initialization is complete, the system enters the thumbnail view state  112 , which is the default state for viewing any captured images. From thumbnail view state  112 , the system can transition to any one of several possible states depending on the action by the user. For example, the capture button can be pressed to enter capture state  114  to perform an image capture. After the image is captured, the button is released to return to thumbnail view state  112 . If the user wishes to change the orientation of the captured image, then activation of rotation button  32  will rotate the captured image 90° with each invocation. Moreover, now that an image is captured in memory  64 , a user can obtain a magnified view of a portion of the image or page by pressing zoom button  28  to enter zoom view state  116 . Similar to thumbnail view state  112 , the magnified image can also be rotated through application of rotation button  32 . The system will return to thumbnail view state  112  through operation of zoom button  28  or performing certain actions such as capture, send, delete, attach, detach, etc. Additionally, the thumbnail view state  112  includes functionality for the empty (no images) state and the image verification state. 
     From thumbnail view state  112 , one of four menu states can be entered depending on the choice made by the user. First, activation of tools button  38  will transition the system into tools menu state  118  where a menu of possible page operations and/or features is exhibited on display  24  as illustrated in FIGS. 4A and 4B. Second, activation of send button  26  will transition the system into send menu state  122  where a menu of options for transferring a page or group of pages to another appliance, device or system is exhibited on display  24  as illustrated in FIG.  5 . Third, activation of delete button  34  will transition the system into delete menu state  124  where a menu of options for deleting a page or group of pages from memory  64  is exhibited on display  24  as illustrated in FIG.  6 . Lastly, activation of help button  36  will transition the system into help menu state  126  where a menu of help topics is exhibited on display  24  as illustrated in FIG.  7 . Once any of the aforementioned menu states is reached, the user can choose a desired menu option by using navigation buttons  42  and  44  and then validating the choice by pressing a confirmation button. In the preferred embodiment of the present invention, the confirmation button is simply the button by which the present menu on display is accessed. An icon indicating the appropriate confirmation button is displayed in the lower left hand side of the menus as illustrated in FIGS. 4 through 7. Menu states may be exited by simply invoking navigation button  46  to transition to a previous state. 
     From some states, an invalid response by the user (i.e., user presses an inactive button) will be ignored or will result in a transition to the default message handler state  128  where the user response is interpreted through the message that was generated internally and a transition is made to the error dialog state  132  to notify the user of their error via a message or graphic on display  24 . Inactive buttons will occasionally also display a blinking icon to communicate to the user the selection of the inactive button and which buttons are active. Alternatively, error dialog state  132  can be entered directly if application software  70  detects an error in the execution of a valid operation. The most common example of this is when the user follows an improper capture path with appliance  22  during the image capture process. 
     The features provided by the zoom view software module  84  will be described hereafter with frequent reference to (a) the architecture and operation of the application software  70  of FIG. 2; (b) the flow charts of FIGS. 9 and 10; and (c )the captured page illustrations of FIGS. 11A-11C and  12 A- 12 C. 
     Operation of the Zoom View Feature 
     Recall from the state diagram of FIG. 3 that when power is provided via switch  56  (FIG. 1C) application software  70  passes through a transient initialization state  108  to reach thumbnail view state  112 , which is the default state for viewing images captured using capture button  54 . The captured image is displayed as a thumbnail size icon on the display  24  (FIG.  1 A). Although the image has been stored in memory, the thumbnail sized icon of the image is not displayed in readable form, but as a miniature version of the full size object. Hence, for the user to confirm if a capture was successful, the user may need to view a “close-up” of the acquired image. The zoom button  28  is provided on the appliance  22  (FIGS. 1A-1D) to execute a zoom into a specific area of the captured image designated by another icon capable of navigation. In the preferred embodiment, an area designating icon is metaphorically a magnifying glass. Once the zoom button  22  is depressed and held, the appliance  22  (FIGS. 1A-1D) enters a zoom view state  116 , where the navigation buttons  42 ,  44 ,  46 , and  48  are activated to position the metaphoric icon over a specific area of the captured image to be magnified. When the zoom button is released the magnifying glass disappears and a zoomed view is generated. 
     FIG.  9  and FIG. 10 are a functional flowchart of the zoom view state  116  of the state diagram of FIG.  3 . Although there are limitless magnifications in which the image can be examined, the preferred embodiment of the invention implements only two magnifications. An image may be magnified to 75 dpi or 150 dpi on the display  24  (FIG. 1A) of the appliance  22  (FIGS. 1A-1D) based on user input. In FIG. 9, after the image is captured, a thumbnail sized image of the captured image is displayed on the display  24  (FIG. 1A) of the appliance  22  (FIGS. 1A-1D) in step  134 . Menu/navigation interface module  104  (FIG. 2) then checks for a message indicating that zoom button  28  (FIG. 1A) has been depressed at decision diamond  136 . If zoom button  28  is depressed and held, zoom view software module  84  updates display  24  (FIG. 1A) as shown in FIG.  11 A. This view indicates that the zoom button  28  (FIG. 1A) has been depressed as the magnifying glass, the metaphoric icon  138  of choice for the preferred embodiment, accompanied by navigational arrows  141 , are displayed in the upper left hand edge of the captured image  142 . Navigational arrows  141  communicate to the user that the magnifying glass metaphoric icon  138  may only be moved down and right in specifying an area to magnify. 
     At decision diamond  144 , menu/navigation interface module  104  determines if zoom button  28  is being held down. At the depression of the zoom button  28  (FIG.  1 A), the metaphoric icon appears surrounded by navigational arrows. In the preferred embodiment, the magnifying glass icon is automatically placed at the top left corner of the captured image as a starting reference point. Only right and down navigation arrows are displayed. If zoom button  28  (FIG. 1A) is held down, this communicates to the user that the metaphoric icon can only be moved in these directions as it is at the upper left edge of the captured image. Once the user moves the metaphoric icon, these directional arrows disappear in the preferred embodiment and the metaphoric icon floats freely across the captured image as long as the zoom button  28  (FIG. 1A) is held down as indicated by step  146 . FIG. 1B illustrates the positioning of the metaphoric icon  138  over a portion of a captured image on the display  11  (FIG. 1A) to be magnified, using the navigation buttons  42 ,  44 ,  46 , and  48  (FIG.  1 A). This illustrates step  146  (FIG. 9) as the metaphoric icon  138  is visible without navigational arrows  141  (FIG. 11A) and the image has not been magnified to 75 dpi, indicating that the zoom button  28  (FIG. 1A) is being held down for navigation. 
     Once zoom button  28  is released, the area designated under the metaphoric icon is zoomed to 75 dpi in step  148  using exploding animation and is centered on the display  24  (FIG.  1 A). Further, the metaphoric icon disappears from the display  24  (FIG. 1A) as shown in FIG.  1 C. 
     In FIG. 10, menu/navigation module interface module  104  checks for another zoom button  28  (FIG. 1A) depression at decision diamond  152 . While waiting for the zoom button to be depressed again, the navigational buttons  42 ,  44 ,  46  and  48  pan or scroll the image if depressed  149 . At the second depression of the zoom button  28  (FIG.  1 A), the metaphoric icon  138  reappears on the image with surrounding navigational arrows  141  as shown in FIG.  12 A. This indicates that metaphoric icon  138  is capable of movement in all directions by navigation buttons  42 ,  44 ,  46 , and  48 . 
     If the zoom button  28  (FIG. 1A) is depressed and held  154 , the metaphoric icon may again be navigated across the image in step  156  to a specific area in the direction of any navigational arrow, only this time, with the image being displayed in 75 dpi as illustrated in FIG.  12 B. Once the zoom button  28  (FIG. 1A) is released, the area of the captured image designated under the metaphoric icon is magnified to 150 dpi in step  158 , once again centered and displayed on the display  24  (FIG.  1 A), using exploding animation as shown in FIG.  12 C. In this view, while waiting for the zoom button to be depressed again, the navigational buttons  42 ,  44 ,  46  and  48  again pan or scroll the image  163 . 
     Menu/navigation module  104  then checks again for a zoom button  28  (FIG. 1A) depression at decision diamond  162 . Once the zoom button  28  (FIG. 1A) is depressed again, then the process returns to step  134  where the image is displayed once again in the thumbnail view using unexploding animation to communicate to the user that a reduction of the image size has occurred. Captures are stored automatically when they become viewable. 
     Thus, the user has the option again to view any area of the captured image  142  in any of the two magnifications using the zoom button  28  (FIG. 1A) and the navigation buttons  42 ,  44 ,  46 , and  48  (FIG.  1 A). At any time, the user has the option of deleting the captured image  142  by invoking delete page module  94  through the delete button  34  (FIG. 1A) or initiating the capture of another image using the capture button  54  (FIG.  2 ). 
     The zoom page view program  84  of the present invention can be implemented in hardware, software, firmware, or a combination thereof. In the preferred embodiment(s), the zoom page view program  84  is implemented in software or firmware that is stored in a memory  64  and that is executed by a suitable instruction execution system. 
     The zoom page view program  84 , which comprises an ordered listing of executable instructions for implementing logical functions, can be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions. In the context of this document, a “computer-readable medium” can be any means that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a nonexhaustive list) of the computer-readable medium would include the following: an electrical connection (electronic) having one or more wires, a portable computer diskette (magnetic), a random access memory (RAM) (magnetic), a read-only memory (ROM) (magnetic), an erasable programmable read-only memory (EPROM or Flash memory) (magnetic), an optical fiber (optical), and a portable compact disc read-only memory (CDROM) (optical). Note that the computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory  64 . 
     In concluding the detailed description, it should be noted that it will be obvious to those skilled in the art that many variations and modifications can be made to the preferred embodiment without substantially departing from the principles of the present invention. All such variations and modifications are intended to be included herein within the scope of the present invention, as set forth in the following claims.
