  The operation flow in the network camera will be described by dividing it into the following four.

  (1) In the mobile terminal 1, communication setting information necessary for communication with the network camera 2 is input, and an image in a specific format is displayed on the screen of the mobile terminal 1.

  (2) The network camera 2 captures an image of a specific format displayed on the screen of the mobile terminal 1 and sets it in the network camera 2 itself.

  (3) In the portable terminal 1, access information is generated and transmitted to the display device 3, and the access information is set in the display device 3.

  (4) The display device 3 receives and displays a captured image from the network camera 2 based on the access information.

  Hereinafter, the operation (1) will be described with reference to FIGS.

  First, the input means 21 in FIG. 2 will be described.

  The user uses the input means 21 to input communication setting information such as the IP address, gateway, and ID of the network camera 2 in the mobile terminal 1 of FIG. At this time, it is realized by starting a dedicated application or the like for inputting the setting information and inputting it using a device such as a keyboard, a numeric keypad, or a touch panel. The input may be performed using voice. The information to be input is not limited to the setting information. For example, information for communication with the display device 3 may be added.

  The operation of the input means 21 will be described with reference to FIG. First, it is confirmed in step S162 whether or not the input from the input device is completed. If the input has not been completed, the process returns to step S162. On the other hand, when the input is completed, the process proceeds to step S163, and the communication setting information input to the portable terminal 1 is stored using the storage unit 22. Thereafter, in step S164, the unique image conversion means 23 is notified. Further, in step S165, the access information generating unit 25 is notified, and the process returns to step S162. In addition, we explained that the user inputs characters into the terminal, but not only by hand, but also by connecting the mobile terminal to the Internet line etc. and downloading the communication information stored in other devices such as a server You may input by doing. In this case, it is possible to eliminate the occurrence of errors due to manual work during input to the mobile terminal.

  Next, the unique image converting means 23 in FIG. 2 will be described. The unique image conversion means 23 converts the information input by the input means 21 into a unique format. The unique image conversion means is realized by converting the input information into a barcode according to a barcode standard such as JAN (Japan Article Number) if it is a one-dimensional barcode. The unique image conversion means is realized by the QR code standard or the like if it is a two-dimensional barcode. In the case of a special character, it is realized by a certain rule such as conversion to a binary number. The unique image may be a general character string as well as a barcode and special characters.

  The operation of the unique image conversion means 23 will be described with reference to FIG.

  First, in step S172, it is determined whether there is a notification from the input means 21 in step S164. If there is no notification, the process returns to step S172. On the other hand, if there is a notification, in step S173, the communication setting information is used to convert the image into a unique format. The unique format is realized by a barcode or the like. Note that a two-dimensional bar code or special characters that can obtain specific information by image recognition may be used as an image in a specific format. Although the description has been given as an image having a specific format, a normal character string may be used.

  After the image conversion is completed in step S173, the unique image display unit 24 is notified in step S174.

  Finally, the unique image display means 24 of FIG. 2 will be described.

  The unique image display means 24 is realized by a liquid crystal display (LCD) or the like. The unique image display unit 24 receives the notification from the unique image conversion unit 23 and displays the screen generated by the unique image conversion unit 23. The unique image display means may display not only the unique image but also other general images. In addition, although demonstrated using the portable terminal, terminals, such as a remote control with the component shown in FIG. 2, may be sufficient. Note that a television with a communication function may be used because it is not necessarily portable.

  Hereinafter, the operation (2) will be described with reference to FIGS.

  Next, the mode selection means 31 of FIG. 3 will be described. The mode selection means 31 is a means for switching between the setting mode and the shooting mode. The configuration of the first embodiment is realized by installing a changeover switch outside the network camera 2. In this embodiment, a changeover switch is provided. However, the changeover switch may be changed by a push button or an electric signal.

  The operation of the mode selection means 31 will be described with reference to FIG.

  In step S192, it is determined whether a notification from the image input means is received. If a notification is received from the image input means 32, the process proceeds to step S193. In step S193, the process is divided by switching the mode selection switch. In the case of the setting mode, the image input by the image input means 32 is handled as a unique image including the communication setting information. If it is a setting mode, it will progress to step S194, will notify the information analysis means 33, and will return to step S192. If it is the shooting mode, the process proceeds to step S195, and the image transmission means 36 is inquired whether the communication setting information such as the IP address is set to determine whether communication is possible. If the result of step S195 is a communicable state, the process proceeds to step S196 to notify the captured image conversion means 35, and the process returns to step S192. If the result of step S195 is not communicable, the process returns to step S192. Here, the flow will be further described assuming that it is the setting mode.

  Next, the information analysis means 33 in FIG. 3 will be described. The information analysis unit 33 performs image recognition processing and acquires necessary information from the analysis result. When the image to be analyzed is a one-dimensional barcode, a two-dimensional barcode, or a special character, it is necessary to use an information conversion algorithm corresponding to each. When the image to be analyzed is a one-dimensional barcode, one-dimensional recognition may be performed at the time of image recognition, and therefore less analysis processing may be required than two-dimensional barcodes and special characters. When the image to be analyzed is a two-dimensional barcode, more information can be included in the image than the one-dimensional barcode. In the information analysis means 33, the information to be acquired may exist other than information necessary for communication set in the network camera 2 itself.

  The operation of the information analysis means 33 will be described with reference to FIG.

  In step S212, it is determined whether a notification from the mode selection means 31 has been received. If no notification has been received, the process returns to S212. If a notification is received from the mode selection means 31, the process proceeds to step S213. In step S213, setting information is analyzed from the input image. In step S214, the setting information is acquired and stored in the information analysis means 33. In step S215, the information setting unit 34 is notified, and the process returns to step S222.

  Finally, the information setting unit 34 in FIG. 3 will be described. The information setting unit 34 acquires communication setting information from the setting information analyzed by the information analysis unit 33 and sets it in the image transmission unit 36.

  The operation of the information setting unit 34 will be described with reference to FIG.

  In step S222, it is determined whether a notification from the information analysis means 33 has been received. If no notification has been received, the process returns to step S222.

  If the notification is received, the process proceeds to step S223, and the information analysis unit 33 stores the communication setting information such as the IP address, gateway, and ID from the stored setting information in the information setting unit 34. deep. Following step S223, in step S224, the image transmission unit 36 is notified, and the process returns to step S222.

  Hereinafter, the operation (3) will be described with reference to FIGS.

  First, the access information generating means 25 in FIG. 2 in the network camera 2 will be described. The access information generation unit 25 generates access information from the communication setting information of the network camera 2. The access information is realized using a URL generated from the IP address of the network camera. An example of the URL is shown in FIG. Although FIG. 18 shows the case of HTTP as the image acquisition protocol, other protocols such as FTP and POP3 can also be used.

  The operation of the access information generating unit 25 will be described with reference to FIG.

  First, in step S182, it is determined whether there is a notification from the input means 21, and if there is no notification, the process returns to step S182. If there is a notification in step S182, the process proceeds to step S183. In step S183, access information to the network camera is generated. Subsequent to step S183, in step S184, the information transmitting unit 26 is notified, and the process returns to step S182.

  Next, the information transmission means 26 in FIG. 2 will be described. The information transmitting means 26 is a protocol used for mobile phones such as CDMA, W-CDMA, IMT2000, etc., a protocol based on an Ethernet (R) network such as 802.11a, b, g, e, etc., Bluetooth ( R), ECHONET (R), and the like. The information transmitting unit 26 may use wired communication. When receiving the notification from the access information generating unit 25, the information transmitting unit 26 displays the IP address, e-mail address, etc., which has been input by the input unit 21 in advance or stored in the storage unit 22 in advance. The access information is transmitted based on the information of 3.

  Next, the first communication means 41 of FIG. 4 in the display device 3 will be described.

  The first communication unit 41 performs communication using the same protocol as the information transmission unit 26 in the mobile terminal 1. When access information is transmitted from the communication means 21 of the portable terminal 1 to the first communication means 41 by e-mail, it is confirmed whether or not it has been received periodically.

  The operation of the first communication means 41 will be described with reference to FIG.

  In step S252, it is determined whether access information has been received. If the access information has not been received, the process returns to step S252. If the access information is received, the process proceeds to step S253, the access destination is stored, the second communication means 42 is notified, and the process returns to step S252.

  Finally, the second communication means 42 in FIG. 4 will be described.

  The second communication means 42 performs communication using the same protocol as the network camera 2. When the first communication means 41 notifies that the access information has been updated, the access destination of the network camera 2 is changed.

  Hereinafter, the operation (4) will be described with reference to FIGS. 15 to 17, 12, and 13.

  First, the second communication means 42 in FIG. 4 of the display device 3 will be described. The second communication unit 42 makes an image transmission request to the network camera 2 on the basis of the access information received by the first communication unit 41 and receives a captured image of the network camera 2.

  The operation of the second communication means 42 will be described with reference to FIG.

  If a notification from the first communication means 41 is received in step S262, the process proceeds to step S264. If not received, the process proceeds to step S263.

  In step S 264, the access information stored in the first communication unit 41 is stored in the second communication unit 42. If access information is stored in the second communication means 42 in step S263, the process proceeds to step S265. If not, the process returns to step S262. In step S265, an image transmission request is transmitted to the network camera 2 based on the stored access information. If it is determined in step S266 that an image has not been received from the network camera 2, the process proceeds to step S268. If received, the process proceeds to step S267.

  In step S267, the received image conversion means 43 is notified, and then the process proceeds to step S262. In step S268, the received image display means is notified that the access destination information is abnormal, and in step S269, the access destination stored in the second communication means 42 is deleted. When the display device 3 includes an input unit, the second communication unit 42 may have a function of canceling the image transmission request at an arbitrary time. By performing steps S268 and S269, it is possible to prevent unnecessary traffic from flowing on the network when the display device 3 and the network camera 2 cannot communicate. The image transmission request may include not only information necessary for communication such as the IP address of the display device 3 but also information for controlling the network camera 2. Thereby, an image requested by the user can be acquired within a range in which the network camera 2 can operate. Hereinafter, the flow when the mode selection unit 31 of FIG.

  Next, the captured image conversion means 35 in FIG. 3 will be described. The captured image conversion means 35 converts the input image input by the image input means 32 into a format that can be transmitted via a network such as JPEG.

  The operation of the captured image conversion means 35 will be described with reference to FIG.

  In step S242, it is determined whether a notification is received from the mode selection unit 31. If no notification has been received, the process returns to step S242. On the other hand, if a notification is received, the process proceeds to step S243, where the input image is converted into a format that can be transmitted by the image transmission means 36. In step S244, the image transmission unit 36 is notified. In step S243, if the image transmission request received in step S233 in the image transmission unit 36 includes information such as resolution and transfer rate, the image transmission unit 36 converts the information into a format corresponding to the image transmission request of the display device 3.

The image transmission unit 36 has a function of transmitting an image in response to an image transmission request from the display device 3 after confirming whether the communication setting information such as an IP address or a gateway is set.

  The operation of the image transmission unit 36 will be described with reference to FIG.

  In step S232, it is determined whether a notification is received from the information setting means 34.

  If the notification is received from the information setting unit 34 in step S232, the communication setting information stored in the information setting unit 34 is stored in the image transmission unit 36 in step S236. If the notification is not received from the information setting unit 34 in step S232, the process proceeds to step S237, and it is determined whether the communication setting information is stored in the image transmission unit 36. If stored, the process proceeds to step S233. If not stored, the process returns to step S232. In step S233, it is determined whether an image transmission request is received. If no image transmission request has been received, the process returns to step S232. If an image transmission request has been received, the process proceeds to step S234, and it is determined whether a notification from the captured image conversion means 35 has been received. If the notification from the captured image conversion means 35 is received in step S234, the process proceeds to step S235, the image converted by the captured image conversion means 35 is transmitted in accordance with the image transmission request, and the process returns to step S232. On the other hand, if the notification from the captured image conversion means 35 is not received in step S234, the process returns to step S234.

  In addition, although it demonstrated using the network camera, as long as it is an apparatus which has a means shown in FIG. 3, you may use the digital still camera with a communication function, and the mobile phone with an imaging function.

  Next, the received image conversion means 43 in FIG. 4 in the display device 3 will be described.
