BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to digital still and video cameras and communication systems, and more particularly to a communication device providing a communication interface between a digital camera and a network system.
2. Brief Description of the Prior Art
Portable digital cameras are generally treated as PC peripheral devices. With conventional digital cameras, a user takes pictures until the camera memory/disk is filled and then downloads the digital image data to a PC. The camera needs to be either connected to the PC, for example through a cable, or a removable storage device such as a PCMCIA card must be manually transferred from the camera to the PC. The need to regularly make a direct, physical connection to a PC reduces the portable nature of digital cameras. In addition, downloading images to a PC is a local operation. In order to move images into the internet, the user must apply another set of commands on the local PC. Such a system is described in U.S. Pat. No. 5,475,441 by Parulski et al. Cameras are also incorporated into integrated systems for displaying an image, such as a visual surveillance system in a retail store. U.S. Pat. No. 5,444,483 by Maeda discloses a system including a digital camera with processing circuitry for display on a television screen.
Another limitation of conventional digital cameras is that there is no direct way to identify an image once it is loaded onto the PC. Additional information must be added manually, such as operator name, account number, camera of origin, etc. Also, there is no way of securing the images to assure that an operator does not alter them once loaded into a PC, or that the images will not be viewed by an unauthorized person as part of the transmission of the images from the PC to a remote location.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an apparatus to serve as an interface for enabling a user of a portable still and or video digital camera to send image data directly from the camera to a communication network for transmission and downloading to a remote network location or remote computer.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to FIG. 1 of the drawing, a preferred embodiment of the communication device 10 of the present invention is illustrated in use with a digital camera 12, PC 14, communication network 16 and a remote destination 18, which can be any type of network object, such as a PC, a printer, phone switch, server, etc. The device 10 has a camera communication port 20 for interconnection to either the camera 12 as indicated by cable 22 to port 24, or to the PC 14 through cable 26. The dashed lines 28 are to indicate that either the camera 12 or PC 14 can be connected to port 20. The device 10 has a network communication port 30 shown connected to the network 16 through line 32, and a Smart card port 34 for installation of a Smart card 36. The connection between the remote destination 18 to the network 16 is indicated by line 38. The communication device 10 includes any of various communication or network apparatus for sending data through the network 16.
The use of the communication device 10 involves first programming it as required. Programming is accomplished through use of a PC 14 connected to port 20 and/or through data entry from the Smart card 36 through the port 34 and/or from a remote computer at destination 18 by way of the network 16. Examples of programming options will be given in the following detailed description. Generally, the device 10 can be programmed to send instructions and data to the camera and to perform operations on data received from the camera, and to send data to the specified remote destination 18 by way of the network 16. Typical uses of the Smart card are for entry of additional data such as a user I.D., camera ID, an address or phone number of the remote destination/network site 18, operational instructions to the camera 12 and communication device 10, etc.
The primary function of the communication device 10 is to perform the necessary operations required to receive data from the camera 12 and then to send the data to the remote destination 18 by way of a selected communication media indicated by network 16. Other operations/functions will be described in the following specification.
The input 20 of the device 10 imitates the back end application of a PC, thus becoming transparent to the camera that operates as if it is communicating to a PC. The communication device 10 establishes communication with a network 16 via a predefined protocol and communication mode. The device 10 receives image data and other information data from a camera 12, and secures the data and structures it according to the required protocol, performs any other programmed operations, and then sends the data through the network for transmission to a destination device 18, such as a computer, printer, server, phone switch, etc., placing the data in assigned locations as defined by the device ID or commands. Communication between the device 10 and the destination device can be bi-directional, i.e. a destination device host 18 can download information to the communication device 10 as well as receive information. Any and all types of media are included in the spirit of the present invention. Particular embodiments of the communication device 10 include the functions of one or more devices including a telephone modem, ethernet adapter, a router, hub, etc. The device 10 can also be configured to transmit through a wireless communication link, such as satellite communication, etc. Signals include infrared, or any RF frequency such as UHF, VHF, or microwave.
In wireless communication between the device 10 and destination 18, line 32 is replaced with a wireless connect inn between the device 10 and the network 16, as indicated by antenna/emitter 40 on the communication device 10 and transceiver 42 connected to the network 16.
FIG. 1 also shows wireless communication between the camera 12 and communication device 10, indicated by a transceiver 44 connected to the camera port 24, and an antenna/emitter 46 on the communication device 10 for sending and receiving data between the camera 12 and device 10. All types of radiated signals are included in the spirit of the invention, the particular type depending on such factors as distance and environment, etc.
Because the device 10 is programmable, there is significant flexibility in its use. For example, device 10 can be programmed to perform functions automatically, for example to receive instruction from a destination device/host computer 16 to direct the camera to take a picture at a particular time of day, or every hour and/or to download images or upload information at a specific time from the camera. The device 10 can be programmed by a destination device 18 to operate a camera “off-line”. After uploading the instruction to the device 10, the communication can be terminated. The device 10 can keep the instructions and send them to the camera appropriately.
In another example, the device 10 can be programmed to automatically connect to the network 16 when the camera image data storage is full, or partially full, and then to download the image data and subsequently disconnect from the network 16. Upon completion of downloading and receiving a confirmation from the destination 18, the device 10 can continue by deleting the image data from the camera.
The communication device 10, or camera if it is programmable, can also be loaded with information to accompany an image, and this information can be included, for example, in an image header. Examples of valuable information may include an account number and a camera ID. The device 10 can be programmed to automatically include this information with image data downloaded to a destination. Such identification avoids confusion as to the source of the image.
The communication device is designed with selected features permanently programmed. An alternate embodiment of the present invention includes permanent programming to allow downloading of data only to a specific destination. Such fixed programming helps avoid theft of the device or camera for a different use. In general, it is a specific feature of the present invention to provide a device with permanent programming for any specific purpose.
Another alternate embodiment includes fixed programming to automatically request and receive a camera ID from the destination device 18, and/or smart card 36 when connected to either of these. The camera ID is then included along with image data. A still further embodiment includes permanent programming to read and increment a counter and assign a unique number to each image received. In this way each image has associated with it a unique number, and the ID of the camera that secured the image. The programming for these functions will be understood by those skilled in the art, and is not shown. The required clock, counter, ROM and other necessary circuit components are illustrated in block form in FIG. 3. In an embodiment wherein the communication device is integrated with a digital camera, the camera ID is programmed into ROM, and therefore no additional request or receiving of a camera ID is required. The operation of including an image number is accomplished in the same manner as with the separate communication device. The integrated camera and communication device will be more fully described in the following text in reference to FIG. 9 of the drawing.
Other embodiments of the communication device 10 include the incorporation of visual 48 and sound 50 indicators to inform a user concerning operations that need to be accomplished. These can function either off or on line. For example, the alarm/sound indicator 50 can be programmed to sound, and/or the visual indicator can light if the device 10 is programmed to connect the camera to the network at a specific time and there is no connection. The indicators can also give notice when the image storage has reached a certain level. A visual display 52 is optional for presentation of useful information such as the remaining number of images to be sent to a destination 18, the remaining time required for transmission, notice of connection to a camera 12, and notice of connection to a destination 18. Internally, the device 10 includes a counter to maintain the image count for display as discussed above, and may optionally also include a clock for use in indicating the date and time of receiving an image on the display 52.
An alternate construction 54 of a device that is functionally similar to device 10 is shown in FIG. 2 wherein the connection from the device 54 to a camera 56, or to the PC 14 is made through a removable storage interface such as a PCMCIA card, SamrtMedia CompactFlash Clik! Card, etc. For example, a PCMCIA card 36 can be placed in the camera card slot 58 and camera data can be downloaded to the card 36. The card 36 can then be placed in the device 54 slot 60, and the camera data can be loaded into the device 54 for processing and transmission through connection 62 to a destination 20. An alternate embodiment is also indicated in FIG. 2, wherein a PCMCIA card extension 64 is provided for installation in the PCMCIA card slot 58 of the camera 56. Other configurations and types of connections in the design of the communication device will be apparent to those skilled in the art and these are to be included in the spirit of the present invention.
Referring to FIG. 3, the internal structure of the communication device 10 is shown in block form. A processor 66 performs operations according to specific programming generally indicated by the image processing block 68, and coordinates the activation of the communication device 10. Specifically noted in the processor block 66 are the operations of maintaining the time and date (clock 70), for inclusion with image data to indicate the time and date of the image processing. The processor also keeps an account of the number of images received and sent (block 72), for display on the LED screen 52, and processes additional data (block 74) for various purposes, including user data to be included with image data. In addition, the processor performs security operations when programmed to do so (block 76). Typically, a ROM 78 is provided to store permanently programmed data, and a RAM 80 is used for temporary storage. Specific camera communication apparatus includes a camera connection controller 82, and an optional infrared transceiver 84 for a wireless connection to the camera. The camera controller 82 connects to the camera through port 20 and/or the transceiver 84, and additional connective hardware as indicated in FIG. 1. The network communication apparatus similarly includes, in addition to the processor and memory blocks, a network connection controller 86, communicating with the network through line 32 and/or connected to a modem 88 through bus 90 and then to the network through a modem output bus 92 and/or a bus 94 to a transceiver 96 to the antenna/emitter 40 via a bus 98 for a wireless connection to the network. Similarly, the camera connection controller 82 is optionally connected via bus 83 to a transceiver 84 connected through bus 85 to antenna/emitter 46 for communication with the camera 12. The user indicators are operated through a user interface controller 108. The indicators include a battery condition indicator 110, the alarm light 48, the sound alarm 50, a power switch 112, and the LED display 52. The power supply 114 is also indicated with options including a battery 116, an AC battery charging supply input 118, a phone line power connection 120 and a line 122 from an alternate power bus, not shown.
FIG. 4 illustrates accommodation of a number of types of network connections with a single communication device 124, including device circuitry 126 similar to that shown in FIG. 3, including a modem 128 and also an Ethernet adapter 130, a router 132, a hub 134, an infrared link 136 and/or any wireless connection 138. The device 124 can be configured to provide compatible data format for any one or more of the possible types of network connections, either individually or simultaneously. In the case of simultaneous output to more than one media, the device 124 includes a separate output for each type of connection. The various selected connection types can each transmit through a corresponding part of network 16 to a single computer or remote network node 18, or they can each output to a different remote destination, such as illustrated in FIG. 5 where output from a camera 12 is sent by a communication device 140 by way of an ethernet adapter 130 through a network 139 to a first remote computer 142, and also by way of a wireless connection/transceiver 138 to a transceiver 42, through a network 141 to a second remote computer 146, or alternately to the computer 142 as indicated by line 148.
The communication devices described in this disclosure can be connected to a camera by any of a variety of port types. This is illustrated in FIG. 6 showing a camera 150 connected to a communication device 152 by way of serial ports 154, 156, SCSI ports 158, 160, IrDa ports 162, 164, parallel ports 166, 168 and USB ports 170, 172 from communication device 152 to the camera 150. The device 152 can have any combination of outputs and other features as described for communication devices elsewhere in this disclosure. As shown, the device 152 has an output port 174 and an optional Smart card port 176 for use with a Smart card 36. The various interconnecting lines or media are simply noted as lines 178, each configured appropriately for the type of port. In the case of infrared communication the corresponding line 178 is not a physical communication cable but rather an unobstructed line of view. The camera and communication device can have one or more of the ports shown in FIG. 6. The spirit of the present invention includes other communication lines or media between the camera and communication device in addition to those shown in reference to FIG. 6, and between the communication device and a remote computer in addition to those illustrated in reference to FIG. 4. Such variations will be apparent to those skilled in the art.
As discussed above, the communication device of the present invention provides downloading of camera images onto computerized systems in an automated manner. The communication device is programmed to include information about the camera, the remote computer and intervening network and the corresponding method of transporting the information.
In addition to these more general features of the communication device, numerous programming and operational options are included in the spirit of the present invention, examples of which are given in the lists of FIG. 7. The types of connections from the communication device to a network were illustrated in detail in FIG. 4. These options are also listed in FIG. 7 under the heading “Device Connection to Network”. Such connections require specific ordering/arranging of data known as protocols. Typical protocols are listed in FIG. 7 under “Device to Network Protocols”. A user will also often find it convenient to include the camera serial number or any other unique identification, along with the image information. Certain types of camera information are listed under “Device Information Re Camera”, and this and other camera information are programmed into a device by use of the Smart card installed for example in port 34 of FIG. 1, or by use of a PC by way of port 20, or from a remote computer at 18 as illustrated in FIG. 1, or by other means that will be apparent to those skilled in the art.
In the same way, information regarding the identity by the particular communication device, and other information can be programmed into the device. Examples include a unique communication device ID, the date and time maintained by a built-in clock, the number of images stored and/or downloaded, and the numbers retained on a consecutive image counter in the communication device. These features are also listed in FIG. 7 under DEVICE GENERATED INFORMATION.
The communication device is also programmed with information concerning the destination 18, which normally will be a remote PC, but could be some other apparatus such as a video monitor or a printer, etc. This type of information is listed under “Device Information Re Destination” in FIG. 7.
Requiring a user password avoids the possibility that an unauthorized person will alter data. Phone number and IP address data can also be loaded into the communication device, and are listed under “Operational Information for Devices and/or Camera” in FIG. 7. Detailed examples of operations to be performed on images will be discussed in reference to FIG. 8.
The communication device programming also includes instructions that are then sent by the communication device to the camera, examples of which are listed in FIG. 7 under “Instruction to Camera From Device”.
The purpose of the communication device is to receive information from the camera and then to store it, or modify it, and/or add to it according to the program and data, and send the required data to the network. Examples of data received from the camera are listed in FIG. 7 under “Device Information From Camera”. Examples of operations performed on image data are included in the list of FIG. 8. A particular embodiment includes the device programmed to add identifiers to the image, such as including the date and time of image acquisition, the user's name, a unique camera I.D. or image I.D. and the date and time of transmission. This data can be placed on the image, or in an image header, or outside the image area. The communication device can also be programmed to mark, i.e. watermark or finger print, which are invisible marks, the images for the purpose of deterring unauthorized use, and/or it can be programmed to prepare image authentication data, or to encrypt the entire set of image data to prevent any unauthorized person from viewing the image. For example, the communication device can be programmed to store and encrypt selected image data points for comparison with data from corresponding locations of a questionable image at a later time.
It is noted in FIG. 8 that the device can also perform other operations such as compressing or expanding files, and parsing files and converting them to different formats.
The specific items listed in FIGS. 7 and 8, and discussed above concerning programming of the communication device are all given by way of example. The basic objective of the present invention is to provide a communication device that will allow a digital camera to be connected to one or more types of communication networks for downloading of data to, and receiving data from a remote destination, which is typically a computer. Details of the circuitry and programming of the communication device do not need to be described in this disclosure because those skilled in the art of digital apparatus will understand how to design the device to perform the operations disclosed and claimed herein.
The embodiments of the present invention illustrated above are preferred embodiments. The communication device is particularly useful in these forms in that it allows existing digital cameras that do not have the functionality to connect to a network, to be connected to any of a variety of communication networks for transmission of image data and receiving instructions. Existing digital cameras do not have to be modified to function with the communication device of the present invention because an interconnection is made through an existing camera port using the existing protocol.
An alternate embodiment of the present invention is illustrated in FIG. 9 wherein a communication device 180 is integrated inside a digital camera 182. containing a digital camera section 184. The novel digital camera 182 can send and receive data to and from a communication network. The camera 182 in this embodiment has a serial port 186 for connection to a line 188 to a PC for receiving programming data, for use in a downloading image data directly to a PC, as in a conventional digital camera. The camera 182 also has one or more communication ports 190 for connection to one or more lines 192 to a communication network. The network communication options discussed for example in reference to FIGS. 4 and 5 also apply to the device 180 of FIG. 9. The operation of the device portion 180, and various features such as the display, indicators, etc. are the same as discussed above in regard to the external communication devices such as 10 or 124. Port 190 is for acceptance of a Smart card 36. Other optional features are not repeated in FIG. 9 for simplicity and to avoid redundant discussion.
FIG. 10 illustrates an embodiment of the invention wherein a communication device 192 is configured for connecting data from a camera 194 directly to a video/TV receiver 196. This connectivity allows both preview of live images from the camera as well as post-view or playback of either still images, or video when applicable.
FIGS. 11 and 12 illustrate communication devices that are configured for transmission to separate destinations. FIG. 11 illustrates a case where the camera 198 is capable of outputting first and second sets of data on lines 200 and 202 respectively, to a communication device 204, and wherein it is desirable to send a first set of data to a first destination 206 and a second set of data to a second destination 208. For example, a journalist may want to send high resolution data to his private PC at destination 206 and send low resolution data to a potential customer for preview at destination 208 prior to placing a purchase order for the image.
Other applications include “escrow” security transmissions where images “first data” are sent to a first location 206, and other information “second data” is automatically sent to a second location/recipient 208. In the case of secured images, an authenticated image can be sent to a first location such as 206 and an image signature and/or authentication data can be sent to a second location 208. Similarly, encrypted or watermarked data can be sent to a first location, and original data to a second location.
In the case where the camera cannot provide both the first and second data, the second data can be prepared by the communication device, as illustrated in FIG. 12. In this case, the camera 210 only outputs original image data. The communication device 212 is programmed to create encrypted image data and/or authentication data, or include other data, and then output first selected data to a first destination/location 206 and a second set of data to location/destination 208.
As referred to in the above description, the device of the present invention performs operations in an automated manner. Novel methods of operation of the communication device and/or integrated camera device will now be described in greater detail.
The communication devices described above, used in a system, for example the system described in FIG. 1 wherein a programmable communication device 10 interconnects a camera 12 with a destination 18, or a similar system with a communication device integrated with a camera as described in reference to FIG. 9, provide a structure capable of automatic and intelligent operation. The computerized destination 18 can be of various configurations, including a single PC or a network server.
The method and apparatus of the present invention in automatic operation has great utility when a plurality of communication devices, either as separate devices or integrated with a camera, are in service and attempts are made to download image data. Image data requires a large memory, and downloading from a number of communication devices is time consuming. Networks encountering such a load of image data can easily be overloaded, requiring either large increases in network band width, or a method of organizing the downloading in an automated manner. Such automation is a particularly useful feature of an embodiment of the present invention and is illustrated in FIG. 13 where three sets of cameras 214, 216, and 218 and communication devices 220, 222, and 224 are connected to a single destination 226 through a network 228.
Various ways of automating the transfer of image data from the cameras to the destination will be understood by those skilled in the art of automation after reading the description of the invention. A preferred embodiment involves programming the devices 220, 222, and 224 to automatically “re-dial” for a hook-up with the destination when a busy signal is received. The destination simply accepts a first call and ignores subsequent calls until the processing of the first call is complete. An alternate method includes the destination storing the numbers of the calling communication devices in the order received, and then notifying the next device in line when the destination is ready for accepting the next download. This approach has an advantage over the re-dialing approach in guaranteeing each device its priority.
Referring now to FIG. 14, an example is illustrated wherein a communication device is programmed to perform automatic operations. Block 230 (set up device) represents the programming that is accomplished through use of a PC 14, Smart card 36, or the computer/destination 18 through a network 16. FIG. 14 is a simplified example of programmed decisions made by a communication device. Details of programming for such operations are well understood by those skilled in the art and therefore are not described in detail.
The example of FIG. 14 illustrates the communication device, for example device 10, programmed to query the camera communication port 20 to determine if a camera is connected. The communication device, for example, can be programmed to check for a camera connection (block 232) at periodic intervals, or at certain times of the day. If the camera is connected, the communication device can then receive and evaluate data from the camera, an operation which can be fully automatic if the camera is programmed to receive and respond to commands through line 22. If not, a user can manually trigger the camera 12 to download the data to the communication device. In either the case of automatic or manual download to the communication device, block 234 represents this function. Block 236 indicates an option for a compatible camera 12, wherein the communication device queries the camera to determine what percentage of the image storage capacity is filled. If it exceeds a certain predetermined amount, for example 75%, the communication device responds by instructing the camera 12 to download the image data (block 234). If not, the device can continue to check for a camera connection and image memory available on a periodic basis, and/or at certain times.
Once image data is loaded, the communication device can respond to programming to perform any of a variety of operations as discussed above, such as encrypting, creating authentication data and relegating selected data for subsequent transmission to one or more destinations. This is indicated simply as block 238.
The communication device can be programmed to send the relegated data at certain times. This programming is symbolically indicated by block 240, and at the programmed time the device checks the output port 30 (FIG. 1) to determine if a connection is made to a network (block 242). If so, the communication device further checks to determine if the destination is connected and ready. This is indicated by block 244 for a single destination and by blocks 246 and 248 for two separate destinations, although any number of destinations are within the scope of the present invention.
Once the communication device determines that the destination is ready, the data is transmitted as indicated by blocks 250, 252 and 254. Block 250 also indicates an option indicating programming of the communication device to include a unique ID with the transmitted data to connect the data to a specific location, i.e. database, within the destination. The purpose of FIG. 14 is primarily to illustrate automation within the communication devices of the present invention. Automation is also possible in the destination 18, and in the camera 12 in those cases where the camera 12 is programmable.
FIG. 15 will now be used to discuss automation within the destination 18. It should also be understood that the present invention includes combinations in which automation occurs in the communication device, camera and destination, or in any combination of the three to accomplish required programming objectives.
Block 258 of FIG. 15 symbolizes programming of the destination 18 to perform operations, examples of which will be described in reference to the various blocks of FIG. 15. Block 260 indicates the destination determining if the communication device is connected to the network. The destination can be programmed to check for a connection at various intervals or times of day, etc. The destination can also be programmed to respond to a signal from the communication device indicating a requirement to transmit data. Both of these options, either an active query to the communication device or a response from the communication device are included in the step indicated by block 260.
Once connection is established between the destination and the communication device, the destination can send instructions to the communication device as indicated by block 262. As with block 260, this action by the destination can be self initiated or in response to an instruction received from the communication device to send data. The data is then received by the destination (block 264) and processed (block 266). The communication device can be either separate from the camera or integrated with it.
FIG. 16 lists examples of data that can be sent by a destination to a communication device including instructions to the communication device to direct the camera to take a picture at a set time or at certain intervals. Account identification, titles or other information can be sent for inclusion in an image header, or for watermarking, etc. Operational data can be sent to inform the user when and where to take a picture. A map showing where to take a picture can be sent, for example, which can be displayed by the user on a camera visual display, and corrective notices can be sent informing the user of any problems with the downloaded image data such as chronic underexposure, focus problems, etc. The destination can also send instructions to the communication device to check camera memory, download data, encrypt data, etc., all controlled by the destination.
Upon receiving data from the communication device (block 264), the destination can automatically process the data according to specific programmed objectives (block 266). A number of possibilities are included in FIG. 16 under “Data Processing by Destination”. In cases where data is received in unencrypted form, it can encrypt and store the data, or it can decrypt encrypted data and print images automatically or archive them. The destination 18 can also automatically distribute selected data items to other remote locations, such as on the web, or e-mail at a low resolution image for inspection prior to a sale. The destination can also store authentication data of an original image and create corresponding authentication data from a questionable image, and compare the two sets of authentication data to determine the validity of the questionable image.
In summary of the automatic features of the invention, the destination, for example a server, can call the communication device to notify it of a particular time to send data to a server, for example based on local and remote network load, server processing load, server storage capacity, fulfillment (printing), system load, and other factors. As explained above, there may be querying/handshaking between the communication device and the server to determine if there are sufficient images to send, i.e. to determine the space available in the image storage memory of the communication device or camera-device. Alternatively, the communication device can query the destination to initiate the sending of data.
Another automatic feature of the present invention is the automatic inclusion of prescribed information along with image data, such information including for example, a unique ID, date, time, etc.
