  The model image data is image data of a photograph taken by another cameraman or the like.

  Hereinafter, communication and processing exchanged between the camera 1 configured as described above and the web server 2 will be described.

  FIG. 2A is a diagram showing an operation flowchart of the characteristic part according to the present embodiment in the control program stored in the ROM 104 executed by the CPU 115 of the camera 1, and FIG. It is a figure which shows the operation | movement flowchart of the characteristic part which concerns on this embodiment among the control programs memorize | stored in ROM201 which the control part 208 of FIG.

  That is, when photographing is performed with the camera 1 (step S101), the obtained image data is stored as temporary storage data on the RAM 105 and stored in the storage unit 106 (step S102). Then, the position data at the time of shooting is acquired by the position information acquisition unit 114, and the image data and the position data are transmitted to the access point 3 managed by a predetermined provider set in advance via the communication unit 112. (Step S103). At this time, in order to reduce the communication amount, the image data may be transmitted in a compressed format instead of the RAW data. After this transmission, the camera 1 waits for reception (step S104). However, when there is no reception within a predetermined time, this operation is terminated, and a normal camera operation such as normal shooting or display of captured image data is started.

  When the data transmitted from the camera 1 is received by the access point 3, the image data and the position data are transferred to the server (web server 2) connected to the network 4 such as the Internet by the router function inside the access point 3. Delivered.

  When the web server 2 receives the image data and the position data (step S201), the feature point detection unit 207A of the image processing unit 207 performs binarization and contour extraction on the image data received from the camera 1. Processing is performed to detect a feature point pattern of the image (step S202). In other words, the received image data is converted into black and white, a corner detection filter is applied to perform determination processing, and the corner position of each part constituting the image is obtained as a feature point. These feature point patterns, that is, the arrangement and distribution of the feature points become the features of the image.

  Then, the feature point comparison unit 207B compares the feature point pattern of the image data extracted by the feature point detection unit 207A with the feature point pattern of the sample image data group stored in the database of the storage unit 203 in advance. Then, a database search is performed using the extracted feature point pattern as a search key (step S203). For example, in the model image data taken at a famous tourist spot, the arrangement information of the feature points (consisting of several hundred points) is extracted in advance as a feature point pattern and configured in the storage unit 203 of the web server 2. Registered in the database. For buildings and the like that change depending on the viewing angle, a plurality of sets of feature point patterns are stored in a database for each viewing angle. Therefore, the feature point pattern is extracted from the captured image data by the same method, the database registered in advance is collated, and the object with the highest matching degree is selected to recognize what the object is. I can do it. At this time, the probability of misrecognition can be reduced by narrowing the model image data to be compared around the position based on the position data received from the camera 1.

  Of course, the present invention is not limited to such a method of detecting feature points and recognizing an object by pattern matching, but adopts other image recognition methods such as a statistical identification method and a structure identification method. It doesn't matter. These statistical identification methods and structure identification methods are well known, and therefore their explanation is omitted.

  If model image data having a feature point pattern that matches the feature point pattern of the extracted image data is not found (step S204), list = 0 is set in camera 1 via communication unit 205. Transmit (step S205). Thereafter, the process returns to step S201 and waits for the next image data and position data to be sent.

  On the camera 1 side, when there is reception (step S104), it is determined whether or not a keyword list has been received (step S105). When the above list = 0 is received, since the keyword list is not received, the CPU 115 displays “no list” on the display unit 108 (step S106), ends this operation, The operation shifts to normal camera operation such as normal shooting and display of captured image data.

  On the other hand, when there is model image data having a feature point pattern that matches the feature point pattern of the extracted image data in the web server 2 (step S204), the image keyword extraction unit 207C Image keywords (for example, Tokyo Tower) registered in association with the model image data are extracted from the storage unit 203, and the extracted image keywords are temporarily configured in the RAM 202 by the image keyword list generation unit 207D. It adds to an image keyword list (step S206). Next, the control unit 208 determines that the image keyword extracted most among the image keywords in the image keyword list is appropriate as the image keyword of the image data received from the camera 1, and the image search unit 207E Then, the model image data associated with the image keyword is retrieved from the storage unit 203 (step S207). That is, the control unit 208 has a function as an image keyword selection unit. Then, the keyword list in which the associated keyword (photographing position, photographing time, user name (photographer name), etc.) attached to the retrieved model image data is added to the image keyword list by the image keyword list generation unit 207D. Is generated (step S208). After the keyword list thus created and the retrieved model image data are transmitted to the camera 1 via the communication unit 205 (step S209), the process returns to step S201, and the next image data and position data are transmitted. Wait for it to come. Note that the amount of communication can be reduced by transmitting the model image data after making it a thumbnail image by the compression / decompression unit 207F. The size of the thumbnail image may be determined in advance, or the display size of the display unit 108 of the camera 1 is determined according to the photographing device information described as the header information of the image data received in step S201. An appropriate image size may be selected according to the size.

  As described above, when there is reception (step S104), the camera 1 side determines whether or not a keyword list has been received (step S105). If the keyword list is received, the keyword list is displayed on the display unit 108 such as an LCD (step S107).

  FIG. 3A is a diagram showing a display example of the keyword list on the display unit 108. This keyword list describes an image keyword 501 representing a subject name (for example, Tokyo Tower), a position 502, a time 503, and a user name 504 associated with each sample image data that matches the image keyword in a list format. It has become. The position is expressed in latitude and longitude. For example, “N: 35/1, 41/1, 774/100 E: 139/1, 48/1, 774, 100” is 35 degrees 41 minutes 7.74 seconds north latitude, 139 degrees 48 minutes 7.74 seconds east longitude. Indicates. This is merely an example, and it is needless to say that any format such as an address or a common name of the place may be used.

  The user of the camera 1 operates the input unit 103 of the camera 1, such as a cross button and an OK button, and selects a desired shooting location from the keyword list (step S108). In response to this selection, a map display corresponding to the display unit 108 is performed (step S109).

  FIG. 3B is a diagram showing a display example of map display on the display unit 108. This indicates, on the map information, a subject position mark 505 indicating the position of the subject, a shooting position mark 506 indicating the selected shooting location, a model image (thumbnail image) 507 shot there, and the current position of the user. The current position mark 508 is superimposed. The map information may be received from the web server 2 or the map information in the camera 1 may be used. Further, when there is a margin in communication capacity, map information may be received from the web server 2, and when there is no margin in communication capacity, the map information in the camera 1 may be used.

  Although not particularly illustrated, the sample image 507 can be enlarged and displayed in the size of the display unit 108 by operating the input unit 103. In this case, instead of enlarging the received thumbnail image, it may be requested to the web server 2 to download and display the model image data suitable for the size of the display unit 108, but there is a copyright. The model image data may not be stored in the storage unit 106 of the camera 1 or may be stored only after some charge is made.

  Further, the keyword list and the map display may be displayed simultaneously as shown in FIG. 4 instead of being separated as shown in FIGS. 3A and 3B.

  As described above, according to the first embodiment, when a user who goes to a sightseeing spot wants to shoot a scene viewed on a guidebook, a poster, a television, etc., he / she guides where to start shooting. The user can take a satisfactory picture.

  For example, Mt. Fuji, Tokyo Tower, etc. have points that are photographed by professional and high amateur photographers particularly well. However, normally, only the image taken by the cameraman from such a point is burned into the user's eyes as a medium, so even if the user who went out with the camera 1 goes to the tourist spot, it is the same If you can't shoot the landscape, you can't be satisfied. In the present embodiment, such a user simply takes the camera 1 and allows the user to easily show a model image to select and introduce the shooting spot information, so that anyone can take a desired photo. Can be possible.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  FIG. 5A is a diagram illustrating an operation flowchart of the characteristic part according to the second embodiment in the control program stored in the ROM 104 executed by the CPU 115 of the camera 1, and FIG. 5B is a control unit 208 of the web server 2. It is a figure which shows the operation | movement flowchart of the characteristic part which concerns on this 2nd Embodiment among the control programs memorize | stored in ROM201 performed. Here, the same reference numerals as those in FIGS. 2A and 2B are attached to the same parts as those in the first embodiment, and the description thereof is omitted.

  That is, on the camera 1 side, if there is a reception after transmitting the image data and the position data in step S103 (step S104), in the second embodiment, it is determined whether or not an image keyword list has been received. (Step S110). When the list = 0 is received from the web server 2, the image keyword list has not been received, so the CPU 115 displays “no list” on the display unit 108 (step S106), and ends this operation.

  On the other hand, when there is model image data having a feature point pattern that matches the feature point pattern of the extracted image data in the web server 2 (step S204), the model keyword extraction unit 207C causes the model image data to be extracted. Image keywords registered in association with the data (for example, Tokyo Tower) are extracted from the storage unit 203 (step S206A), and the extracted image keywords are temporarily configured in the RAM 202 by the image keyword list generation unit 207D. It adds to an image keyword list (step S206B). Then, the image keyword list is transmitted to the camera 1 via the communication unit 205 (step S210). After this transmission, the web server 2 waits for image keyword selection (step S211). However, if the selected keyword is not received within the predetermined time, the process returns to step S201 and waits for the next image data and position data to be sent.

  On the camera 1 side, when there is a reception as described above (step S104), it is determined whether or not an image keyword list has been received (step S110). Here, when an image keyword list is received, The image keyword list is displayed on the display unit 108 such as an LCD (step S111). In that case, for example, the image keyword “Tokyo Tower” and the image keyword “Kyoto Tower” are displayed so as to be selectable on the camera 1 (when the search target is narrowed down by the position data, there is no possibility that both towers are listed at the same time. However, for the sake of clarity, both towers are listed here). The user of the camera 1 operates the input unit 103 of the camera 1, for example, the cross button and the OK button, and selects a desired image keyword from the image keyword list (step S112), and the CPU 115 selects the selected image keyword. Is transmitted to the web server 2 via the communication unit 112 (step S113). After this transmission, the camera 1 waits for reception of the selection list (step S114), and ends this operation when there is no reception within a predetermined time.

  When the web server 2 receives the selected image keyword (step S211), the control unit 208 causes the image search unit 207E to store the model image data associated with the selected image keyword from the storage unit 203. Search is performed (step S212). Then, the image keyword list generation unit 207D generates a selection keyword list including accompanying keywords (photographing position, photographing time, user name (photographer name), etc.) attached to the searched model image data (step). S213). After that, a thumbnail image of the retrieved model image data is created by the compression / decompression unit 207F and transmitted to the camera 1 through the communication unit 205 together with the created selection keyword list (step S214), and then the above step Return to S201.

  On the camera 1 side, when the selected keyword list is received (step S114), the selected keyword list is displayed on the display unit 108 such as an LCD (step S115). This display is the same as the display of the keyword list displayed in step S107 in the first embodiment. Therefore, a desired shooting location can be selected from the selected keyword list (step S108), and a map display corresponding to the display unit 108 can be performed (step S109).

  As described above, when the control unit 208 selects an arbitrary image keyword, in the first embodiment, the image keyword extracted most among the image keywords in the image keyword list is selected as an appropriate image keyword. However, in the second embodiment, the image keyword is selected based on the operation input by the user of the camera 1. Therefore, it is possible to present the model image of the subject desired by the user and the shooting position thereof more reliably.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.

  FIG. 6A is a diagram showing an operation flowchart of the characteristic part according to the third embodiment in the control program stored in the ROM 104 executed by the CPU 115 of the camera 1, and FIG. 6B is a control unit 208 of the web server 2. It is a figure which shows the operation | movement flowchart of the characteristic part which concerns on this 3rd Embodiment among the control programs memorize | stored in ROM201 performed. Here, the same reference numerals as those in FIGS. 5A and 5B are attached to the same parts as those in the second embodiment, and the description thereof will be omitted.

  That is, in the third embodiment, the web server 2 side waits for reception after transmitting the image keyword list to the camera 1 via the communication unit 205 (step S210) (step S215). Then, when there is no reception within the predetermined time, the process returns to step S201.

  On the other hand, on the camera 1 side, after the image keyword list is displayed on the display unit 108 such as an LCD (step S111), if the user looks at the displayed image keyword list and there is no desired image keyword, the input unit 103 Input NG instruction. Therefore, the CPU 115 determines whether or not an NG instruction has been issued (step S116), and if an NG instruction has been issued, transmits the NG instruction to the web server 2 via the communication unit 112 (step S117). . Then, a message such as “Please change the composition and take a picture again” or “Shoot with another composition” is displayed on the display unit 108 (step S118), and the process returns to step S101. On the other hand, when no NG instruction is given, a desired image keyword is selected from the displayed image keyword list (step S112), and the selected image keyword is sent via the communication unit 112. This is transmitted to the web server 2 (step S113).

  On the web server 2 side, if the communication unit 205 has received the message (step S215), it is determined whether an NG instruction has been received (step S216). If so, the process returns to step S201, and the next It waits for image data and position data to be sent. On the other hand, when the NG instruction has not been received, the operation from the above step S212 for retrieving the model image data associated with the received selected image keyword from the storage unit 203 is executed. Become.

  As described above, in the third embodiment, when a user-desired image keyword is not searched, the image keyword list can be canceled. Then, by performing imaging again, it is possible to acquire the model image and its imaging position.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described.

  FIG. 7A is a diagram showing an operation flowchart of the characteristic part according to the fourth embodiment in the control program stored in the ROM 104 executed by the CPU 115 of the camera 1, and FIG. 7B is a control unit 208 of the web server 2. It is a figure which shows the operation | movement flowchart of the characteristic part which concerns on this 4th Embodiment among the control programs memorize | stored in ROM201 performed. Here, the same reference numerals as those in FIGS. 6A and 6B are attached to the same parts as those in the third embodiment, and the description thereof will be omitted.

  That is, as described above, when the model image data having the feature point pattern that matches the feature point pattern of the extracted image data is not searched on the web server 2 side (step S204), the communication unit 205 is set. List = 0 is transmitted to the camera 1 (step S205), but in the fourth embodiment, the process waits for reception (step S215) instead of returning to step S201, and within a predetermined time. Only when there is no reception, the process returns to step S201.

  On the camera 1 side, when such a list = 0 is received, “no list” is displayed on the display unit 108 as described above (step S106). Instead of ending the operation, the user can input a desired image keyword by key input from the input unit 103 or by voice recognition using the MIC 110 and the voice control unit 111 (step S119). Then, after the input image keyword is transmitted to the web server 2 via the communication unit 112 (step S120), it waits for reception of a selection list (step S114).

  On the web server 2 side, when received by the communication unit 205 (step S215), the model image data associated with the received selected image keyword or input image keyword is retrieved from the storage unit 203 (step S217). ). And the process after said step S213 which produces | generates the selection keyword list | wrist including the accompanying keyword accompanying the searched model image data is implemented.

  Also, when an NG instruction is given at step S116 on the camera 1, the process proceeds to step S119, and the image keyword is input and transmitted as described above.

  As described above, in the fourth embodiment, when a user-desired image keyword is not searched, the image keyword is input on the camera 1 side and retransmitted to the web server 2, so that the user-desired hand The main image and its shooting position can be acquired.

  The web server 2 may additionally register the input image keyword in the database of the storage unit 203 in association with the transmitted captured image data. In this case, the captured image may be registered as model image data, or may be registered as user image data that is not a model image but is used only for extracting image keywords. By accumulating a large number of such user image data, the image keyword extraction accuracy can be improved.
