The second program to be installed is installed.

  The second image processing unit 43 is a device such as a DSP that performs arithmetic processing, and a captured image of a web page corresponding to the URL information included in the content of the two-dimensional image code 12 is recorded in the second recording unit 42 or the like. If not, the captured image of the captured web page is adjusted to a size suitable for the imaging device 20 via the second communication unit 46 or the network (resizing).

  The second communication unit 46 communicates with the imaging device 20 to transmit and receive information. Specifically, when the captured image of the web page corresponding to the URL information included in the content of the two-dimensional image code 12 is not recorded in the second recording unit 42, the second communication unit 46 via the network. In order to acquire a captured image of the web page corresponding to the URL information, signal transmission / reception for accessing the web page is performed, or the captured image is transmitted to the first communication unit 26. The second control unit 49 controls each unit of the capture image supply device 40 such as a CPU (execution of the second program, etc.).

  An operation procedure on the imaging device 20 side when displaying a captured image of a web page corresponding to URL information included in the content of the two-dimensional image code 12 will be described with reference to a flowchart of FIG. When the user operates the operation unit 21 of the imaging device 20 and starts an operation of superimposing and displaying the captured image, the first program is activated, and the first control unit 29 controls each unit such as the imaging unit 25, Steps S11 to S19 are performed (the first program is executed).

  In step S11, the imaging unit 25 images the imaging target unit 10 (imaging process). The image of the subject 10 obtained in the imaging process is subjected to image processing by the first image processing unit 23 and displayed on the display unit 24. The imaging process is performed every first time t1 (for example, 1/30 second), and the display unit 24 performs a through image display for updating an image displayed every first time t1 (live view display).

  In step S <b> 12, the first control unit 29 determines whether or not the image of the photographing object 10 obtained by imaging includes the two-dimensional image code 12 that can be decoded (decoded) by the first image processing unit 23. to decide. If it is included, the process proceeds to step S13. If it is not included, the process returns to step S11.

  In step S <b> 13, the first image processing unit 23 specifies a portion where the two-dimensional image code 12 is present in the image of the photographing object 10 obtained by imaging, and decodes (decodes) the content of the two-dimensional image code 12 ( Decryption process).

  In step S <b> 14, the first control unit 29 determines whether URL information is included in the content of the two-dimensional image code 12. If it is included, the process proceeds to step S15. If it is not included, the process proceeds to step S19.

  In step S15, the first control unit 29 transmits the URL information included in the content of the two-dimensional image code 12 decoded in step S13 to the capture image supply device 40 via the first communication unit 26 (transmission step). ).

  In step S <b> 16, the first control unit 23 determines whether capture image information has been received from the capture image supply device 40 via the first communication unit 26 (there is a reception process). If received, the process proceeds to step S17. If not received, step S16 is repeated. However, if the captured image information is not received even after the second time t2 (for example, 30 seconds) has passed since the URL information transmission in step S15, the fact that the capture image acquisition has failed is displayed on the display unit 24, and the process returns to step S11. There may be a process.

  In step S17, the display unit 24 superimposes the capture image on the through image (first display step). At this time, the region including the two-dimensional image code 12 is tracked, and the position on the through image on which the captured image is superimposed, corresponding to the position, size, degree of deformation, orientation, and the like of the region including the two-dimensional image code 12, There may be a step of changing the size, the degree of deformation, the direction, and the like.

  The degree of deformation of the region including the two-dimensional image code 12 is caused by the positional relationship between the imaging device 20 and the actual object 10 to be captured, and the original shape (square or rectangular) of the region including the two-dimensional image code 12 is used. Degree of deformation compared to. The direction of the area including the two-dimensional image code 12 is the direction on the screen of a specific part in the area including the two-dimensional image code 12 (for example, the outer shape of the area from the center of the area including the two-dimensional image code 12 on the screen). Is specified by the image pattern of the region including the two-dimensional image code 12.

  In step S18, the display unit 24 displays a guide for confirming to the user whether to activate the browser and display a web page corresponding to the captured image (see FIG. 5). When the user selects to display the web page corresponding to the captured image using the operation unit 21, the first control unit 23 starts the browser and displays the web page corresponding to the captured image. Display on the unit 24 (second display step). Further, there may be a step of recording URL information and a captured image in the first recording unit 22 by the user's selection or automatically.

  In step S19, the display unit 24 superimposes the content of the two-dimensional image code 12 on the through image. At this time, the region including the 2D image code 12 is tracked, and the content of the 2D image code 12 is superimposed in accordance with the position, size, degree of deformation, orientation, etc. of the region including the 2D image code 12. There may be a step of changing the position, size, deformation degree, orientation, etc. on the image.

  Next, an operation procedure on the captured image supply apparatus 40 side when displaying a captured image of a web page corresponding to URL information included in the content of the two-dimensional image code 12 will be described with reference to the flowchart of FIG.

  In step S <b> 31, the second control unit 49 receives the URL information included in the content of the decoded two-dimensional image code 12 transmitted from the first communication unit 26 of the imaging device 20 by the second communication unit 46. Determine whether or not. If received, the process proceeds to step S32. If not received, the standby state is maintained.

  In step S32, the second control unit 49 determines whether the second recording unit 42 has recorded a captured image of the web page corresponding to the URL information received in step S31. If so, the process proceeds to step S33. If not, the process proceeds to step S34.

  In step S33, the second control unit 49 reads the captured image of the web page that is recorded in the second recording unit 42 and that corresponds to the URL information received in step S31.

  In step S34, the second control unit 49 accesses the web page corresponding to the URL information received in step S31 via the second communication unit 46 or the network, captures a captured image of the web page, and performs second recording. Record in part 42.

  In step S35, the second image processing unit 43 displays the captured image read from the second recording unit 42 in step S33 or the captured image captured in step S34 on the imaging device 20 as necessary. Resize (reduce) to an appropriate size. Note that when the captured image is captured in step S34, if the size sufficient to display on the imaging device 20 is taken into consideration, such a resizing process may be unnecessary.

  The degree of reduction takes into consideration the effective display area of the display unit 24 of the imaging device 20, the processing capability of the first image processing unit 23 and the first control unit 29 of the imaging device 20, the communication speed of the first communication unit 26, and the like. Although it is desirable to be determined, the image may be reduced to a certain image size. Information such as the effective display area of the display unit 24 of the imaging device 20, the processing capability of the first image processing unit 23 and the first control unit 29 of the imaging device 20, and the communication speed of the first communication unit 26 are obtained from the imaging device 20. 1 can be collected through the communication unit 26.

  In step S <b> 36, the second communication unit 46 transmits the captured image to the imaging device 20. After the transmission, the operations of steps S16 to S18 are performed on the imaging device 20 side.

  Instead of accessing the web page corresponding to the URL information in step S34 and capturing the captured image of the web page, the second control unit 49 converts the URL information into the URL information via the second communication unit 46 or the network. It is also possible to check whether there is an external device that can obtain the captured image of the corresponding web page, receive the captured image of the web page corresponding to the URL information from the external device, and record it in the second recording unit 42. .

  Since the contents of the image code cannot be understood by looking at the two-dimensional image code 12, it is necessary to decipher using a machine whether or not URL information is included. Whether the URL information is useful information for the user is difficult to understand only by the URL information, and it is necessary to acquire and check information on the web page. However, when using a browser, it is necessary to execute the browser software separately from the software that uses the digital camera function for capturing the image code.

  In the present embodiment, since the web page corresponding to the URL information is displayed as a captured image on the through image display of the display unit 24, it is not necessary to run a browser to view the web page, and the digital camera function is used for the through image display. It is possible to visualize the contents of a web page while continuing image display. Since it is only necessary to check the captured image and access the web page if necessary, it is possible to select an appropriate web page before accessing the web page. For this reason, it is possible to reduce the troubles (such as time to start the browser, data communication cost, and trouble of operation) due to accessing the web page using the browser.

  In particular, when there are several two-dimensional image codes 12, it is possible to continuously display captured images and select an appropriate web page for the user.

  Further, since the content of the web page can be confirmed with the captured image without accessing the web page with the browser of the imaging device 20, the risk (computer virus infection, etc.) when the web page is accessed with the browser can be avoided.

  In addition, the object 10 including the two-dimensional image code 12 includes information related to the content of the two-dimensional image code 12 (for example, in FIG. 1 and FIG. "Please read the image code and access the homepage." In the present embodiment, the description content of the photographic subject 10 and the two-dimensional image code 12 are displayed as a through image, and a web page related to the description content is displayed thereon as a capture image. There is also a merit that makes it easier to understand visually.

  The captured image of the web page corresponding to the URL information recorded in the second recording unit 42 is updated every fourth time t4 (for example, one week) so that the latest one can be obtained. Also good. Specifically, when the fourth time t4 has passed since the date and time when the captured image was acquired, the latest captured image is captured by accessing the web page and recorded in the second recording unit 42.
