  • the central processor 202 may compress or downsize the image data as stored in the storage module 206. Compression may be by any known and/or suitable compression application.
  • Downsizing may be to downsize the images to, for example, thumbnail size. Compression and/or reduction are used to reduce the amount of memory in storage module 206 that is required to store the image data. Any compressed and/or reduced images will be noted and not resent to the pre-selected web site. Furthermore, any images that are sent to the preselected web site may be flagged as having been sent, and may not be resent in the future. However, the central processor 202 may send a prompt to the display 110 asking if old images are to be sent again, or only new, and previously unsent, images. Appropriate action will be taken by central processor 202 after the selection is made in the manner described above.
  • the wireless transceiver module 204 is used to wirelessly receive digital data from an external source 600.

Detailed Description of the Exemplary Embodiments
The exemplary embodiment is a method and digital camera to manage digital content for portable digital camera 100 via a wireless media. The portable digital camera 100 may be a digital camera, digital video camera, digital voice recorder, or digital diary. As shown, it is a digital camera. The digital camera 100 has a slot 102 into which a memory card 200 is inserted in the usual manner.
The memory card 200 is shown in Figure 3 and has a central processor 202, a wireless transceiver module 204 operatively connected to the central processor 202, and a storage module 206 operatively connected to the central processor 202. The central processor 202 has a card interface 208 as well as a wireless interface 210. The wireless transceiver module 204 also has an antenna 212.
The digital camera 100 has an inbuilt processor 104 with a card interface 106 for interfacing with the memory card 200 when inserted into slot 102. The inbuilt processor 104 also has a display interface 108 for controlling the display screen 110 of the camera 100. Furthermore, the inbuilt processor 104 has a control interface 112 for enabling the camera control buttons and so forth 114 to be used to control the operation of the camera 100. The inbuilt processor 104 is incapable of independently exporting digital data externally of the camera 100. By independently exporting it is meant that the processor 104 requires the camera 100 to be operatively connected to an intelligent host such as a computer that has the relevant operative software to enable the export of the data to the computer from the camera, the exporting being under the control of the computer. The normal operation of the camera 100 is under the control of the inbuilt processor 104.
The inbuilt processor 104 is also incapable of independently importing digital data from externally of the camera 100. By independently importing it is meant that the processor 104 requires the camera 100 to be operatively connected to an intelligent host such as a computer that has the relevant operative software to enable the export of the data to the camera from the computer (i.e. import of the data by the camera from the computer), the exporting/importing being under the control of the computer.
Due to the card interface 208, whenever memory card 200 is engaged in the slot 102 of the camera 100 (500), the card interface 106 sees the memory card 200 as a normal memory card and will interface with it in the usual manner for transferring image and/or audio data from the inbuilt processor 104 to the memory card 200 (501). If the card 200 is not of a category recognised by the camera 100, it will display an error message in the normal manner and the process ends (502).
Once the initial connection between the inbuilt processor 104 and the card 200 is concluded, and upon the camera control being set to a predetermined mode such as, for example, "view" (or its equivalent such as, for example, "play" or "display" or "transfer data") (503), the inbuilt processor 104 downloads from card 200 the first image file for display on the display T10 in accordance with normal operations. The central processor 202 then sends to the display interface 108 an index image file containing a first menu (504), with the navigation controls of controls 114 being able to be used in the normal manner for controlling the displayed menu. The first menu will contain a series of first items for determining the future performance of the camera 100. Each of the items of the first menu is a separate image within the index image file. The first menu items may include, for example: 1. transfer data
2. wireless detect
3. view image.
If at (503) the camera 100 is not set to the predetermined mode - "view" or its equivalent - the memory card 200 and the inbuilt processor 104 operate in the normal, known manner (505) under the operation of the inbuilt processor 104.
If the camera 100 is set to the predetermined mode, one of the displayed items must then be selected (506). As each item in the menu is a separate image, selecting one item in the menu list is selecting a separate image. Therefore, the controls 114 used must be such that the processor 104 can send an instruction to the central processor 202. There are normally two such instructions when in the view mode - "next" (send next image) and "delete" (delete this image). As "next" is required for the following operations, the "delete" function can be used. However, when the camera 100 is in the "view" mode AND if either "transfer data" or "wireless detect" is selected from the first menu items given above, the central processor 202 will interpret "delete" as "select". When the "send first image" instruction is sent by the processor 104 and is received by memory card central processor 202 (504), the central processor 202 recognizes that the camera 100 is in the "view" mode as this is the only time such an instruction is received.
As each of the first menu items is a separate image, by using "delete" not only is an instruction sent from processor 104 to central processor 202, but the instruction contains an identifier of the image to enable the central processor 202 to know which image is to be deleted.
The central process 202 receives the instruction and, after confirming that the predetermined mode has been selected AND that the image selected is either (1) or (2) from the image index file, the central processor 202 treats the "delete" instruction as "select".
The central processor 202 will then take the necessary action depending on whether first menu item 1 or first menu item 2 was selected.
A query is raised (509) to determine if the first menu item selected is for wireless transfer. If not, it must be item 3. If item 3 is selected in the normal manner using controls 114 (507), the central processor 202 will treat the instruction in the normal manner and send the first image file from the storage module 206 (508) and the camera 100 and memory card 200 will continue to operate in the normal manner (505). If at (509) the first menu item selected is for wireless transfer, it could be item 1 or item 2. So a second query is raised (510) to determine if item 1 or item 2 was selected.
If at 510 item 2 was selected, the central processor 202 will activate the wireless transceiver module 204 (511) and a search will be undertaken for potential wireless networks to which the card 200 can be connected (512). This will be in the normal manner. Once all potential wireless networks are detected (513) they are displayed on the display 110 (514) and the controls 114 are used to select the desired wireless network (515). Upon the desired wireless network being selected a second index image file is downloaded from the central processor 202 to the display 110 (516). The second index image file contains a second menu list (517). The second index image file may be the same as the first index image file, or may be different. Each of the second menu list is also a separate image and has its own identifier. The second menu list may be the same as the first menu list, or may be different. The second menu list may include items such as, for example:
1. transfer data
2. wireless detect
3. view image
If at (510) item 1 is selected from the first menu list, the central processor 202 will determine if a wireless network has previously been selected (521). If not, it will revert to item 2 (510) and commence the search for potential wireless networks, as is described above. If a wireless network has previously been selected, the central processor 202 sequentially obtains the image data for the various image files (522) and, using the wireless transceiver module 204, uploads the image data to the selected, pre-determined web site (523). Upon uploading completing, a "completion" message may be displayed on display 110 (524) then the process ends (525). If item 1 is selected from the second menu list at (518) and as the pre-determined web site is known and the network has just been selected, the central processor 202 will commence to download all the image files from the storage module 206 and transfer them to the wireless transceiver module 204 for wireless uploading of the image data to a predetermined web site. If there is more than one pre-determined web site, the central processor 202 will send a list of the pre-determined web sites for display on the display 110 and, after one has been selected in the normal manner, will use the selected, predetermined web site as that to which the image data is to be sent. The list of pre- determined web sites may be by their URL, or by a previously-entered abbreviated name and may include an email account at a web site.
The entry of the pre-determined web site is by previously operatively connecting the memory card 200 to a computer (not shown). The computer will upload the necessary interface from the central processor 202 and the computer will be used to enter the URL of the desired web site or web sites, or the email account, which is then stored in the storage module 206 of the memory card 200.
As such, when the camera 100 has been used to capture images that are stored in the storage module 206 of the memory card 200 in the normal manner, upon the camera controls 114 being set to the predetermined mode such as view, the procedure described above will commence. When in the camera 100 is in the predetermined mode, the central processor 202 and the wireless transceiver module 204 will then operate to send the image data to the selected, pre-determined web site over the Internet 300 so the images can be stored in the storage 402 of the server/PC or other computer 400. This may be done at a convenient time such as, for example, overnight when the camera 100 would normally not be in use. In addition, when the camera 100 is in the predetermined mode it may be used to download the image data from the selected, predetermined web site over the Internet 300 to enable the images to be stored in the storage module 206. This may be required if the images had previously been deleted from the storage module 206.
If desired or required, when the uploading of all the image data is completed, the central processor 202 may compress or downsize the image data as stored in the storage module 206. Compression may be by any known and/or suitable compression application.
Downsizing may be to downsize the images to, for example, thumbnail size. Compression and/or reduction are used to reduce the amount of memory in storage module 206 that is required to store the image data. Any compressed and/or reduced images will be noted and not resent to the pre-selected web site. Furthermore, any images that are sent to the preselected web site may be flagged as having been sent, and may not be resent in the future. However, the central processor 202 may send a prompt to the display 110 asking if old images are to be sent again, or only new, and previously unsent, images. Appropriate action will be taken by central processor 202 after the selection is made in the manner described above.
In Figure 6 there is shown a second exemplary embodiment where the wireless transceiver module 204 is used to wirelessly receive digital data from an external source 600. In this exemplary embodiment the external source is a remote camera 600, such as, for example, a security camera that is used for capturing images or video. However, it may be, for example, a camera similar to the portable digital camera 100 so that sharing of images or video may take place on a camera-to-camera basis. The remote camera 600 may have image, video and/or audio capturing capability. It should have a wireless module capable of wireless communication by at least one relevant and appropriate standard such as, for example, Wi-Fi or Bluetooth. The remote camera 600 has wireless capability for transmitting image or video data (including audio) over the network 300 to the wireless module 204, or directly to the wireless module 204. This may be by use of WiFi, the Internet, Bluetooth, or otherwise as required.
With reference to Figure 5, if the digital camera 100 is in the predetermined mode at 503 there may be a further query by a further menu item to determine if the memory card 200 is to be used to upload digital data captured by the digital camera 100, or is to be used to receive digital data from the remote camera 600. If it is upload, the digital camera 100 operates as described above. If it is to receive, the digital camera 100 is used to receive and display the digital data sent by the remote camera 600. The digital data received by the digital camera 100 from the remote camera 600 may also be stored in the storage module 206.
In this way the digital data captured by the remote camera 600 can be displayed and/or stored by the digital camera 100. In that way if the remote camera 600 is a security camera and it detects an intrusion, it can be viewed on the digital camera 100 as long as the digital camera 100 is able to wirelessly receive the digital data. Appropriate action can then be taken. The security camera 600 may be of any suitable nature or form with the only requirement being a capability of wireless transmission. The wireless transmission module may be integral with the security camera 600 or may be a separate component, the security camera 600 and the separate component being operatively connected.
If the remote camera 600 is a camera similar to the digital camera 100 with a memory card 200, file sharing can take place on a camera-to-camera basis without the need for email, websites or other removable storage devices. However, it may be over the Internet or any other network if required or desired.
As can be seen, for both exemplary embodiments the memory card 200 will be able to connect to the host device 100 without any driver installation or modification of the software running on the host device 100 and is thus "plug-and-play".
The memory card 200 may include a digital rights management module for copyright protection of content downloaded to the memory card 200 storage module 206.
Furthermore, when in the predetermined mode the central processor 202 may over-ride any auto-off or auto-shut-down of the camera 100 to enable the camera 100 to continue to operate until it is taken out of the predetermined mode.
Whilst the foregoing description has described exemplary embodiments, it will be understood by those skilled in the technology concerned that many variations in details of design, construction and/or operation may be made without departing from the present invention.
