  The overall configuration of the image processing apparatus 100 shown in FIG. 1 is as described above. Next, functions and the like realized by the image processing apparatus 100 in FIG. 1 will be described in detail. In addition, about the structure (part) shown in FIG. 1, the code | symbol of FIG. 1 is utilized in the following description.

  FIG. 2 is a diagram illustrating a specific example of the processing executed by the image processing apparatus 100. The input image illustrated in FIG. 2 is a specific example of a facility guidance image to be scanned. In the specific example shown in FIG. 2, the input image (facility guidance image) includes guidance information on a plurality of facilities corresponding to genres such as restaurants, sightseeing, and shopping. The input image illustrated in FIG. 2 includes guide information indicating the name and contact information of the facility in characters and guide information indicating the location of the facility on a map.

  For example, when image data obtained by performing a scanning process on an input image (facility guidance image) illustrated in FIG. 2 is obtained, the image analysis unit 120 executes the image analysis process on the image data. The image analysis unit 120 extracts guidance information of facilities (including buildings serving as landmarks) included in the facility guidance image, for example, by performing image analysis processing on the image data.

  In the case of the image analysis processing for the image data of the input image illustrated in FIG. 2, for example, by known character recognition, the names of a plurality of facilities and the contact information (such as telephone numbers and mail addresses) indicated by characters in the input image are displayed. Information is obtained.

  Further, the image analysis unit 120 recognizes a character indicated in an image area such as a map included in the facility guidance image, and converts an image near the character or an image including the character to the character. It may be extracted as a facility. In the case of the image analysis processing for the image data of the input image illustrated in FIG. 2, for example, the character of “city hall” shown in the map is recognized, and the rectangular figure closest to the position of the character corresponds to “city hall”. It is extracted as the figure that was done. If there is a graphic including the character “City Hall” inside, the graphic may be extracted as a graphic corresponding to “City Hall”.

  When the facility guidance information included in the facility guidance image is extracted, the processing target selection unit 130 selects a processing target according to the purpose of use of the facility guidance image from the extracted facility guidance information. The processing target selection unit 130 selects, for example, guidance information of the facility of interest according to the purpose of use of the facility guidance image as a processing target.

  For example, if the initial purpose of use for the input image (facility guidance image) illustrated in FIG. 2 is a tourist guide and the purpose of use is changed to a disaster map, it is extracted in the input image of FIG. From the guidance information on the plurality of facilities, for example, “city hall” which is an evacuation site in the event of a disaster is set as a noted facility, and guidance information corresponding to “city hall” is selected as a processing target as guide information of the noted facility.

  When the processing target is selected, the image processing unit 150 performs image processing on the image data acquired by the image data acquiring unit 110 according to the purpose of using the facility guidance image. The image processing unit 150 executes, for example, image processing on the image data to emphasize the guidance information of the facility of interest selected as the processing target. The image processing unit 150 may execute, for example, an image processing process for directly emphasizing the guidance information of the facility of interest, or may process information other than the facility of interest so as to be inconspicuous, thereby providing guidance information of the facility of interest. May be executed to indirectly enhance the image processing.

  Specific examples of the image processing performed by the image processing unit 150 include processing such as color conversion processing, character string emphasis processing, filling processing, and character string addition processing.

  In the color conversion process, for example, a process of coloring a processing target image portion to emphasize the processing target, a process of reducing the color of an image portion other than the processing target to make the processing target stand out, and the like are executed. In the character string emphasizing process, for example, a process of changing the font type, character color, character size, and the like of the character string related to the processing target to emphasize the character string to be processed is executed.

  In the filling process, for example, a process of making the image portion other than the processing target inconspicuous by filling the image portion other than the processing target is performed. In the character string adding process, for example, a process of adding a character string that is newly determined to be necessary due to a change in the purpose of use is performed.

  For example, in the case of image processing processing on the image data of the input image illustrated in FIG. 2, a rectangular graphic corresponding to a city hall in a map is emphasized by a color conversion processing, and a character corresponding to a facility other than the city hall is processed by the color conversion processing. Columns are reduced in color. Note that the character string corresponding to the facility other than the city hall may be made inconspicuous by the filling process. In addition, the character strings of the city hall and its contact information are emphasized by the character string emphasis processing, and the character string of “Disaster shelter map” is added by the character string addition processing.

  Thus, image data after the image processing is obtained. For example, if image processing is performed on the image data of the input image (facility guidance image) illustrated in FIG. 2, image data corresponding to the output image illustrated in FIG. 2 is obtained as the facility guidance image after the image processing. .

  If reference information according to the purpose of use of the facility guidance image has been acquired, the reference information may be used in the selection of the processing target and the image processing.

  FIG. 3 is a diagram illustrating a specific example of the reference information. Specific examples of the reference information include, for example, disaster-related information such as evacuation site information and danger spot information provided by the country or local government. FIG. 3 shows a specific example of the evacuation site information and the danger site information.

  For example, if the guidance information of “city hall” is extracted in the image analysis processing on the image data of the input image (facility guidance image) illustrated in FIG. The disaster-related information may be acquired from a local government (city) corresponding to the above. Specific examples of the disaster-related information obtained from the local government corresponding to the “city hall” shown in FIG. 2 are the evacuation site information and the danger spot information illustrated in FIG.

  The evacuation site information illustrated in FIG. 3 includes “north public hall”, “south public hall”, and “city hall” as the evacuation sites. Among these evacuation sites, “city hall” is included in the input image (facility guidance image) illustrated in FIG. For example, when the evacuation site information illustrated in FIG. 3 is obtained as the reference information, the processing target selection unit 130 determines the information of the facility extracted in the image data of the input image (facility guidance image) illustrated in FIG. From among them, the city hall designated as the evacuation site in the evacuation site information of FIG. 3 may be selected as the facility of interest.

  Further, the reference information may be used for the image processing performed by the image processing unit 150. For example, the evacuation site information illustrated in FIG. 3 which is a specific example of the reference information includes a telephone number of a city hall designated as an evacuation site. On the other hand, the character string extracted in the image data of the input image illustrated in FIG. 2 also includes the telephone number of the same city hall. In this case, a process of emphasizing the number (0xxxxxx) of the telephone number included in the image data of FIG. 2 may be executed.

  As described above, when the contact information such as the telephone number included in the reference information is also included in the facility guidance image, an image processing process that emphasizes the contact information included in the facility guidance image may be executed. When the contact information indicated in the reference information is not included in the facility guidance image, an image processing process for adding the contact information in the facility guidance image may be executed.

  Further, for example, the dangerous spot information illustrated in FIG. 3 which is a specific example of the reference information includes information of a road that is closed according to a dangerous condition. Therefore, for example, when there is a dangerous spot corresponding to the dangerous spot information in the image data to be subjected to the image processing, the image processing for displaying the place corresponding to the dangerous spot may be executed.

  FIG. 4 is a diagram showing a specific example of the image processing for displaying a place corresponding to a dangerous place. The input image illustrated in FIG. 4 is a specific example of a facility guidance image to be scanned. "Prefectural road BB route" and "National highway AA route" are shown in the map of the input image illustrated in FIG.

  For example, when the image data of the input image (facility guidance image) illustrated in FIG. 4 is to be processed, the image analysis unit 120 includes the “prefectural road BB route” and the “prefectural road BB” included in the map of the input image in FIG. Recognize the character of "National Highway AA", extract the linear figure closest to the position of the character of "Prefectural Road BB" as the figure of the road corresponding to "Prefectural Road BB", Is extracted as a road graphic corresponding to "National Highway AA Route".

  The dangerous spot information illustrated in FIG. 3 includes “prefectural road C99”, “prefectural road X8”, and “prefectural road BB” as roads to be closed. “Prefectural road BB” among these roads that are closed to traffic corresponds to “prefectural road BB” included in the map of the input image in FIG. 4.

  Therefore, when, for example, the dangerous spot information illustrated in FIG. 3 is obtained as the reference information, the image processing unit 150 outputs the “prefectural road BB route” in the image data of the input image (facility guidance image) illustrated in FIG. Is reduced (or may be filled or erased), and a display such as a character or a symbol indicating that the portion corresponding to the image portion is a dangerous portion is added. Thereby, for example, an output image illustrated in FIG. 4 is obtained as the facility guidance image after the image processing.

  It should be noted that roads other than “Prefectural Road BB Route” included in the map of the input image illustrated in FIG. 4 are not designated as dangerous places of road closure by the dangerous place information illustrated in FIG. 3. Therefore, when the image data of the input image (facility guidance image) illustrated in FIG. 4 is to be processed, for example, an image corresponding to a road that is not designated as a closed road as an evacuation route to a city hall that is an evacuation site Image processing for emphasizing (linear figures) may be executed.

  In addition, in the description using FIGS. 3 and 4, a road that is closed to traffic is illustrated as a specific example of a dangerous place, but a specific example of a dangerous place includes a dangerous place of a landslide disaster or a dangerous place of a river flood. It is.

  In addition, image analysis is performed on the photographic images included in the image data of the facility guidance image, for example, when images of mountains, rivers, the sea, and the like are posted, according to a disaster that has occurred, those images are displayed. Image processing may be performed on the image. For example, when a photograph image of a mountain is included in the image data of the facility guidance image and disaster-related information of a landslide disaster is obtained, the photograph image of the mountain is notified of the danger point. Image processing may be performed.

  The preferred embodiment of the present invention has been described above, but the above-described embodiment is merely an example in every aspect, and does not limit the scope of the present invention. The present invention includes various modifications without departing from the essence thereof.
