<Example 1>
As a first example of the present embodiment, a process for navigating to a shooting point at which a reference image can be shot based on the difference between the reference image and the on-site shot image will be described. FIG. 3 is a flowchart showing the flow of the shooting navigation process of this embodiment, and FIG. 4 is a diagram for explaining the shooting navigation process of this embodiment.

  First, the CPU 19 stores in the external memory 29 the image data of the photograph A (reference image, FIG. 4A) with an ideal composition taken by the user (step S101). The reference image assumed here is a photographic image taken by a user who viewed a poster, a magazine, or the like, but may be acquired through a network such as the Internet.

  Then, the CPU 19 stores in the external memory 20 the image data of the photograph B (field photographed image, FIG. 4B) photographed by the user at a famous landmark where the subject included in the reference image exists (step S102). . Further, the position information of the shooting location of the photo B is acquired by the GPS receiving unit 37 (step S103).

  Next, the CPU 19 displays the photograph A (reference image) and the photograph B (field-captured image) superimposed on the display 33 (step S104). The user can move both displayed images on the screen via the touch panel 31, and touch a plurality of common portions when the subjects are overlapped. For example, based on either the photograph A (reference image) or the photograph B (field-captured image), the other is moved so that the subject overlaps, and a plurality of common portions are pointed. Then, the CPU 19 (comparison point designating unit 110) accepts an input to the touch panel 31 by the user and designates a plurality of common portions of both images (step S105).

  Subsequently, the CPU 19 (image comparison unit 120) calculates a difference between other common parts when one of the designated common parts is superimposed. This is performed for all common locations (step S106). As shown in FIG. 4C, the difference between pointing 2, 3,..., N (only pointing 2 is shown in the figure) when pointing 1 is overlapped is calculated. Similarly, the difference between the pointing points 1, 3,..., N when the pointing 2 is overlapped is calculated. This is performed up to pointing n, and the difference between each pointing is obtained.

  Then, the CPU 19 (movement information calculation means 130) calculates movement information such as a movement direction and a movement distance from the shooting location of the photograph B to the ideal shooting point from the obtained difference information of both images (step S107). The ROM 20 stores table data in which a difference amount between two image data generated by photographing the same subject from different positions and positional relationship information of the two photographing positions are associated with each other. By using the table data, it is possible to determine how far the shooting location is in which direction when the common portions of the two image data are different in coordinates. That is, the CPU 19 (movement information calculation means 130) uses the difference information between the reference image and the on-site photographed image and the table data to determine the direction in which the photograph B is taken and how much the ideal photographing point is to be moved. Ask.

  Subsequently, the CPU 19 displays a map on the display 33 using the position information acquired by the GPS receiver 37 and the calculated movement information, and performs navigation to an ideal shooting point for the user (step S108). Navigation to the ideal shooting point may be performed by outputting voice through the speaker 35 or displaying movement information on the display 33 in addition to the map display.

<Example 2>
As a second example of the present embodiment, a process for navigating to a shooting point where a reference image can be shot based on the difference between the reference image and the field shot image will be described. The difference from the first embodiment is that one of the images to be compared is converted into 3D and angle information is obtained in addition to the movement information. FIG. 5 is a flowchart showing the flow of the shooting navigation process of this embodiment, and FIG. 6 is a diagram for explaining the shooting navigation process of this embodiment.

  First, the CPU 19 stores the image data of the photograph A (reference image, FIG. 6A) of the ideal composition photographed by the user in the external memory 29 (step S201). Further, the CPU 19 stores in the external memory 20 the image data of a plurality of photographs B (locally photographed images, FIG. 6 (b)) photographed by the user at a famous landmark where the subject included in the reference image exists (step S202). ).

  Then, the CPU 19 (3D modeling means 150) converts the photograph B (local photographed image) into 3D using a plurality of image data (step S203). Further, the position information of the shooting location of the photo B is acquired by the GPS receiving unit 37 (step S204).

  Next, the CPU 19 superimposes and displays the photograph A (reference image) and the photograph B (field-captured image) on the display 33 (step S205). The user uses, for example, either the photograph A (reference image) or the photograph B (field-captured image) as a reference, moves the other so that the subject overlaps, and points a plurality of common portions. Then, the CPU 19 (comparison point designating unit 110) accepts an input to the touch panel 31 by the user and designates a plurality of common portions of both images (step S206).

  Subsequently, the CPU 19 (image comparison unit 120) calculates a difference between other common parts when one of the designated common parts is superimposed. This is performed for all common locations (step S207).

  Then, the CPU 19 (movement information calculation means 130) determines from the obtained difference information of the two images from the shooting location of the photograph B (in the case of the present embodiment, the last shooting location among a plurality of shootings) to the ideal shooting point. Movement information such as a movement direction and a movement distance is calculated. Further, the CPU 19 (angle information calculation means 140) calculates angle information (azimuth and elevation angle) of the 3D image from the obtained difference information of both images (step S208).

  Next, the CPU 19 displays a map on the display 33 using the position information acquired by the GPS receiver 37 and the calculated movement information and angle information, and performs navigation of the shooting angle up to the ideal shooting point and the subject for the user. (Step S209).

<Example 3>
As a third example of the present embodiment, a process for setting shooting information for shooting a reference image based on a difference between the reference image and the on-site shot image will be described. FIG. 7 is a flowchart showing the flow of the shooting information setting process of this embodiment, and FIGS. 8 to 10 are diagrams for explaining the shooting information setting process of this embodiment.

  First, the CPU 19 stores the image data of the photograph A (reference image, FIG. 8A) of the ideal composition taken by the user in the external memory 29 (step S301). Further, the CPU 19 stores in the external memory 20 the image data of the photograph B (on-site photographed image, FIG. 8 (b)) photographed by the user at a famous landmark where the subject included in the reference image exists (step S302). . Further, the position information of the shooting location of the photo B is acquired by the GPS receiving unit 37 (step S303).

  Next, the CPU 19 superimposes and displays the photograph A (reference image) and the photograph B (local photographed image) on the display 33 (step S304). The user uses, for example, either the photograph A (reference image) or the photograph B (field-captured image) as a reference, moves the other so that the subject overlaps, and points a plurality of common portions (FIG. 8C). Then, the CPU 19 (comparison point designating unit 110) accepts input from the user to the touch panel 31 and designates a plurality of common portions of both images (step S305).

  Subsequently, the CPU 19 (image comparison unit 120) calculates a difference between other common parts when one of the designated common parts is superimposed. This is performed for all common locations (step S306).

  If the movement information cannot be calculated from the obtained difference (step S307 / NO), the CPU 19 (view angle aperture adjusting means 160) uses the calculated difference to determine the focal length and aperture value for photographing with an ideal composition. Shooting information is obtained and set (step S308).

  As an example of the case where movement information cannot be calculated from the obtained difference, an image difference due to a difference in angle of view as shown in FIG. 9 or an image difference due to a difference in background as shown in FIG. Is mentioned. The ROM 20 captures table data in which the difference between two image data generated by photographing the same subject at different angles of view and the angle of view information of the two image data, and the same subject with different aperture values. The table data in which the difference between the two image data generated in this way is associated with the aperture value information of the two image data is stored. By using the table data, the difference between the focal points when the common parts of the two image data are different in coordinates and the size of the subject is different. It is possible to determine how much the aperture value differs when the background image in the image data differs. In other words, how much the CPU 19 (view angle aperture adjusting means 160) can adjust the focal length and aperture value by using the difference information between the reference image and the field-captured image and the table data to capture a photo as close as possible to the photo A. And set up.

  In the above, the obtained shooting information is set and the user is allowed to take another shot. In addition to this, an image that is as close as possible to the photo A is obtained by performing image processing on the photo B based on the obtained shooting information. May be configured to generate. For example, as shown in FIG. 10, image processing can be performed in stages based on the blur pointing 2 of the photo B, displayed on the display 33 each time, and can be determined by the user when the photo A is approximated.

  On the other hand, when the movement information can be calculated from the obtained difference (step S307 / YES), the CPU 19 (movement information calculating means 130) determines the ideal shooting point from the shooting location of the photo B from the obtained difference information of both images. The movement information such as the movement direction and the movement distance up to is calculated (step S309). Then, the CPU 19 displays a map on the display 33 using the position information acquired by the GPS receiver 37 and the calculated movement information, and performs navigation of the shooting angle up to the ideal shooting point for the user and the subject (step S310). .
