    Image rendering device {IMAGE-RENDERING DEVICE}
    [2] Image projectors have become a popular way to present presentations to an audience and are used for personal and business purposes. Image projectors are generally used to project computer images and / or presentations onto a screen.
    [3] Some image projectors are configured so that a user can access a presentation by connecting the projector and a computer. In general, a user must physically connect an image projector to his computer, such as a personal computer. This process can be cumbersome and frustrate the user. For example, a compatibility issue between the hardware and software of a computer and an image projector. In addition, the connection to the image projector may require a number of cables and / or adapters to allow the user computer to be connected to an available projector. It is not uncommon to lose or misconnect cables and adapters.
    [4] Therefore, it is difficult for multiple presenters to use the same projector. For example, when transitioning from the first presenter to the second presenter, the first presenter must physically connect the computer and image projector with the appropriate adapter and cable. After that, the first presenter is seated close to the image projector. At this point, if the second presenter wants to present his presentation, the first presenter disconnects his computer from the video projector, so that the second presenter can connect the new computer to the image projector, perhaps using a different adapter and cable. Should be. In addition, the first presenter must exchange seats with the second presenter to provide the second presenter with space to connect the image projector. The transition from the first presenter to the second presenter can take a considerable amount of time, which can lead to disruption of the meeting.
    [5] There is a need for a portable and easy-to-use device that allows multiple users to easily connect to an image projector regardless of the computing platform, storage location or presentation format used by the user. Moreover, it would be useful if the presenter could present from anywhere in the venue. In addition, it would be useful if the device could easily connect peripheral devices such as printers, scanners, cameras, etc. to the image projector.

Optionally, instead of an integrated connector, the projector connector 16 may be attached remotely to the image projector 12 via a cable and a suitable plug.
    [19] Any suitable plug can be used in the present invention. One example of a suitable projector connector is a standard video plug. The use of a standard video plug allows the image rendering device 14 to be used in a variety of image projectors with standard outlets. For example, projector connector 16 may be a Video Electronics Standards Association (VESA) M1 plug, corresponding to the M1 standard video interface available for most image projectors. For example, the M1 plug may be a digital connector (eg, M1-D connector), an analog connector (eg, M1-A connector), or digital and analog connectors (eg, M1-DA connector), or the like. Any display socket interface is not limited to these.
    [20] The image rendering device 14 uses a suitable power supply. For example, the projector connector 16 includes a power supply that allows the image rendering device 14 to draw power from the connector 16. An example of such a projector connector 16 is the Besa M1 plug. In addition, the projector connector 16 can support both analog display requirements and digital display requirements.
    [21] 2, the image rendering device 14 will be understood in more detail. Specifically, the main body 15 of the image rendering device 14 may include at least one image receiver 24 configured to receive a number of different data transmission devices 26, shown for example 30, 32, 34, 35. Include. Each data transfer device is intended to provide an image, presentation, slide or other type of data to transfer to an image rendering device 14 from an independent source, such as an external computer or mass storage device. External computers, which will be discussed in more detail below, include, but are not limited to, personal computers, laptop computers, portable computers, and the like, as well as suitable computing devices including them.
    [22] The data transmission device 26 allows the image rendering device 14 to receive images from multiple sources. The data transmission device 26 may be a card, an expandable board, an adapter, or any other suitable device that is plugged into the slot 28 of the image rendering device 14. Note that the slot 28 is configured to allow the insertion and removal of different cards from the image rendering device 14 quickly and easily. Slot 28 is appropriately sized so that cards of standard size can be inserted into slot 28.
    [23] Any number of different data transfer devices 26 are interchangeably received in slot 28. For example, the data transmission device 26 may be a network interface card such as a wired network card 30 or a wireless network card 32 or the like. In particular, the wired network card 30 may be an IEEE 802.3 standard wired LAN (LAN) interface card, such as Ethernet, 100BASE-T standard (IEEE 802.3u), Fast Ethernet, IEEE 802.3z, Gigabit Ethernet and / or other suitable wired. It includes a network interface. The wireless network card 32 includes a wireless len card such as IEEE 802.11a, 802.11b, 802.11g, 802.11x, etc., a radio card, a Bluetooth radio card and / or a ZigBee radio.
    [24] Regardless of the type, each network interface card enables communication between the image rendering device 14 and one source, for example, a remote computer, a server, a network, and the like. This communication enables transmission of an image or presentation stored in an independent source to an image rendering device. A concrete implementation example of different network interface cards in the image rendering apparatus 14 will be described in more detail with reference to FIGS. 2 and 3.
    [25] Slot 28 may be configured to accept other types of data transmission devices. For example, the data transmission device 26 may be a presentation card 34. Presentation card 34 may be any suitable type of mass storage device. For example, the presentation card 34 may be a memory card, flash memory card, solid state memory card, hard disk, or the like. The user inserts the presentation card in which the presentation has been previously stored into the image receiver 24. Then, the pre-stored image is automatically sent to the image projector 12. Optionally, the user can navigate the display menu on the screen to select a presentation. This arrangement is particularly useful if one or more presentations are stored on the presentation card.
    [26] The software is provided in the image rendering device 14 so that the image rendering device 14 can transform and render the predetermined images into a projectable image. For example, software is provided within the image rendering device 14 so that the pre-stored presentation can be represented with dynamic graphics and other animations. In particular, the presentation is stored in a graphics primitive format and / or in a compressed and uncompressed format or in a format rendered as a projectable image by the image rendering device 14.
    [27] Other applications for using a presentation card in the image rendering device 14 are best described with reference to a standard digital camera. Typically, standard digital cameras include some type of memory device, such as a nonvolatile memory card that stores digital images, or other mass memory devices. The image receiver 24 is configured to receive a memory device that allows images stored in the memory card and / or mass memory device to be represented by the image projector 12. In addition, the image rendering device 14 is configured to render an image from the memory card to show the slide show. In addition, it is noted that when a slide show is in progress, the user may order, assimilate, insert transitions and / or alter.
    [28] The image rendering device 14 also includes at least one peripheral connector 36 in the body 15. Peripheral connector 36 is configured such that at least one peripheral device is operatively linked to image rendering device 14 to allow an image to be transmitted from the peripheral device to image projector 12 and vice versa. Peripheral connector 36 may be any suitable connector. For example, the peripheral connector 36 may be a standard connector such as a universal serial bus (USB) port, an IEEE 1394 port, a parallel port, an enhanced parallel port (EPP), an extended cpabilities port (ECP), or the like. Note that one or more peripheral connectors may be provided to the body 15 of the image projector.
    [29] As shown, any number of peripherals 38, 40, 42, 44, etc. may be coupled to the image rendering device 14 via the peripheral connector 36. Exemplary peripherals may include, but are not limited to, the printer 38, the camera 40, the scanner or document camera 42, other peripherals 44, and the like. As described above, the image is sent from one of the peripheral devices to the image projector 12 and vice versa. In this way, the scanned image is sent to the image rendering device 14 and displayed on the image projection screen via the image projector 12. Similarly, the images stored in the camera are transferred directly from the camera to the image projector 12 and displayed on the image projection screen. In addition, the displayed image or presentation is relayed back by the image rendering device 14 and printed by the printer 38.
    [30] 3 illustrates a representative electrical logic system block diagram of an embodiment of the invention. 3 is for the purpose of illustrating the invention, not intended to limit the scope of the invention. Specifically, image rendering device 14 includes a central processing unit (CPU) or processor 100 configured to automatically transmit images from image receiver 24 and / or peripheral connectors to an image projector for display. Image transmission includes rendering and / or decompressing images in accordance with the format of the received image.
    [31] Processor 100 is connected to graphics controller 102 via bus 104. Graphics controller 102 processes and produces an image projected by image projector 12. The buffer 105 is directly connected to the graphics controller 102 and provides a temporary memory for the graphics controller 102. The image rendering device 14 further includes memory, such as a programmable read memory dedicated pyrom (PROM), random access memory (RAM), and the like, coupled to the processor 100 and graphics controller 102 via a bus 104. Other types of memory may also be used.
    [32] Peripherals, including network interface card 108 (including connector 109) and USB host 110, are also coupled to processor 100 and graphics controller 102 via the same bus 104. The USB host 110 is connected to the USB-A connector 111 and / or the USB-B connector 112 and also directly connected to the Besa M1-D plug 114. The graphics controller 102 is connected to the Besa M1-D plug 114 via an analog interface and / or a transition mimimized differential signaling (TMDS) transmitter 116. Graphics controller 102 is also connected to Bessa M1-D plug 114 via display data channel 118.
    [33] An audio converter with a stereo jack 122 is shown at 120 to allow audio to be output through external and / or internal speakers. The Bluetooth transceiver 124 is installed to accommodate a Bluetooth radio card. The compact flash interface 126 is also provided such that a compact flash card or other data transmission device such as "30, 32, 34, 35", etc. shown in FIG. 2 is inserted into and used in the slot 28.
    [34] As described in the above, the image rendering device 14 is powered from the image projector via M1-D 114 or from a similar device via the Besa M1 interface. Power converter 128 is also used inside the system. Optionally, power is supplied through the power jack 130.
    [35] 4 shows a usage environment in which the image rendering apparatus 14 is executed. In particular, the image rendering device 14 is shown in the network environment 61. Network environment 61 includes a number of different devices such as computers, laptops, servers, portable computers, and the like. Insertion of the appropriate network card into the image rendering device 14 allows the presentation content stored in each network device to be selectively sent by the image projector 12 to the image rendering device 14 for display. As shown, the image projector 12 displays the received image on the screen.
    [36] As described above, the network interface card may be a wireless network card or a wired network card. The wireless network card 32 shown in FIG. 2 is adapted to be selectively removable in the slot 28. It will be appreciated that wireless network card 32 may be permanently integrated within the image rendering device without departing from the scope of the present invention. The wireless network card 32 allows multiple users to alternately link their computers to the LAN to send images / presentations to the projector without having to manually connect their computers individually to the image projector. In addition, the model and type of the computer connected to the image rendering device 14 are irrelevant as long as the user's computer device can be linked to the LAN using standard protocols to transmit and receive data. Wireless connection does not require an adapter or cable. Thus, users can present at any location in the venue.
    [37] Such a system is particularly useful in environments such as conference rooms where multiple users with different operating systems and / or platforms wish to present using a single projector system. For example, in FIG. 4, five computers, such as two portable laptop computers 56 and 58, a desktop computer 60, a portable computer 62, and a telephone 64, are connected to an image rendering device 14 via a wireless LAN. ) Is shown. Any one user can link to the image protector 12 wirelessly through the image rendering device 14. Always presenter must release or end the currently active presentation in order to enable the second presenter to send data to the image rendering device 14 for presentation.
    [38] It will be appreciated that any suitable computer or computing device capable of wirelessly linking to a LAN and sending an indicator of an image URI or other image location to the image rendering device 14 may be used in the present invention. Computers used herein include, but are not limited to, desktop computers, portable computers, laptop computers, servers, mainframes, telephones, and the like.
    [39] The image rendering apparatus 14 enables transmission of data to the image projector 12 by connection of the user's computer and the image projector 12. In some embodiments, image rendering device 14 communicates a projector name coupled to a user computer. Thus, when the user connects to the communication network in which the image projector 12 is located, the projector may appear from the icon or may be added to the projector list connected to the computer. In this situation, the user selects a particular image projector to connect from the projector list. 5 illustrates an exemplary user interface. Exemplary user interfaces include a selection window 66 for display on computer screen 67, but other formats are possible. The user interface includes a projector icon 68. This projector icon 68 is used to identify the projectors currently available on the network. As shown in FIG. 5, for example, “projector 1” is connected to the user's computer via the image rendering device 14. Optionally, the user can select the desired projector from the projector list 70.
    [40] The user interface also includes a presentation file 72 configured to allow a user to save a presentation or image for display. When the user wants to give a presentation, the wireless card is inserted into the image receiver 24 of the image rendering device 14. The name or identifier of the linked projector is broadcast to the user's computer, indicating that the user can connect to the image projector and send an image and / or presentation to the image rendering device 14. The user then selects the presentation from the presentation file 72 and sends the selected presentation to the linked projector via the projector icon 68. The user does not need to physically insert an adapter or a cable into his or her computer to move the computer next to the image projector or to connect with the image projector. Instead, the user simply connects to the wireless network and sends the desired image or presentation to the image projector. In addition, the user does not have to sit all the time and does not need to move closer to the image projector during the presentation.
    [41] As discussed above, the images are transmitted from the user's computer to the image rendering device 14 in various formats. For example, an image file (screen shot or screen scrap) corresponding to the display appearance on the user's computer is sent to the image laddering device 14. Typically, the screenshot is sent in a compressed format. The decompressed data may be transmitted to the image rendering device 14. The type of compression depends on the type of image, for example, a photographic image may have low spatial frequencies. While the text is compressed with a compressor suitable for, the text is compressed with a compressor suitable for high spatial frequencies.
    [42] The use of screen scraping has some inherent limitations with regard to graphics capabilities when sending screenshots to the image rendering device 14. Specifically, bandwidth limitations hinder the ability to quickly send complex and / or dynamic graphics to an image projector for rendering. Similarly, animation is difficult to represent using the screen scraping format.
    [43] Image data is transmitted in other formats using reduced transmission bandwidth. For example, an image stored on a user's computer may be converted into a graphic primitive, resulting in a file that is much smaller than the screenshot, and then sent to the image rendering device 14. Graphic primitive transmissions will minimize the requirement. For example, presentations may be web standard formats developed by the World Wide Web Consortium (W3C), such as the Scalable Vector Grapfics (SVG) format, the Dynamic Hypertext Markup Language (DHML) format, and the Extensible Markup Langage (XML) format. Or compressed video formats, including but not limited to formats such as XML and Synchroized Multimedia Impression Language (SMIL) formats. Note also that formats other than the W3C format can be used, including the VML (Vector Markup Language). Corresponding software is stored in the image rendering device 14 to render and display the image in the image projector 12.
    [44] Representative methods suitable for use in the present invention for wirelessly transmitting images to an image projector are described in Slobodin, Hoeye, Olson, Long, Girardelli and Duffy, filed June 7, 2001, for "Transmitting wireless images to a projector. Apparatus and Method thereof, and is incorporated herein by reference.
    [45] Note that in some embodiments, the user's computer may transmit image data directly to the image rendering device 14. Alternatively, the user computer may send a universal resource indicator (URI) to the image rendering device 14, which directs the image rendering device 14 to a suitable location for importing the desired image / presentation.
    [46] The image rendering device 14 also provides a user ability to control the aspect of the presentation via a control device connected to the image projector. For example, image projector 12 includes a remote control device or other user device that allows the presenter to control the image projector. In such a case, the image rendering device 14 sends input commands to the user computer to the remote control device or another device. This configuration allows the user to control the computer through the remote control device.
    [47] As discussed above, a wired network card 30 may be housed in the image receiver 24. The use of the wired network card 30 allows the image rendering device 14 to be physically connected to a user computer via a wired interface. Thus, when the wired network card 30 is retained in the slot 28, any one of the computers 56, 58, 60, 62, 64 shown in FIG. 4 may have a physical connection such as a cable or optical cable connection. Is linked to the image rendering device 14 by connecting the computer to the same network. It will be appreciated that the wired network card may be permanently integrated into the image rendering device within the scope of the present invention.
    [48] With the use of a wired network card in the image rendering device 14, a user may include, but is not limited to, a LAN or wide area network (WAN), public (eg, the Internet, etc.) network or personal network, etc. Can link to any suitable network. In one application, the user may use the image rendering device 14 for internet browsing. For example, the user locates the presentation using a remote device or other suitable user device linked to the image projector 12 and selects the desired presentation. In another application, image rendering device 14 may be a client, for example a thin client, where the user computer provides server software and the image rendering device provides client software. In such applications, much of the processing takes place on the user's computer. The wired network card also allows a remote server to provide a presentation via a server / client session between the image rendering device and the remote server.
    [49] 6 illustrates a network environment in which the present invention may be implemented. As shown in FIG. 6, the image rendering device 14 is integratedly connected to the LAN 74 via a wired and / or wireless network card. The image rendering device 14 may also be linked to the second LAN 76 and / or wide area network 78 such as the Internet. The image rendering device 14 may also connect to the remote server 80 or the user device 82 via the LAN 74. This configuration allows the user to run a presentation to the image projector 12 from a remote location.
    [50] Note that the image rendering device 14 is compact and portable. Typically, the image rendering device 14 is much smaller and lighter than a typical laptop computer. In addition, no input device such as a keyboard or mouse is required. The image rendering device 14 is an automatic rendering engine configured to automatically render an image and send it to an image projector for display.
    [51] While various optional embodiments and configurations of an image display system have been shown and described above, those skilled in the art will recognize that numerous other embodiments, configurations, and modifications are possible and within the scope of the present invention. Note, for example, that image rendering device 14 may be separate from image projector 12 and may be permanently integrated within image projector 12. In addition, the image rendering device 14 may include a plurality of image receivers 24 and / or a plurality of peripheral connectors 36.
