Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a photographic image related information writing method, and more particularly to a photographic image related information writing method for writing information related to a photographic image on a recording medium storing an image photographed by a digital camera.
[0002]
[Prior art]
There is a conventional example in which an image (digital camera image) taken by a digital camera is read into a car navigation device (car navigation system) and the digital camera image is pasted at a point designated by a user. However, since the digital camera image has no position information, the user has to associate the digital camera image with the map position on the car navigation system.
[0003]
As a similar system, the above operation can be performed using an Internet service, but the basic operation is the same, and it is necessary to associate a point on the map designated by the user with the digital camera image to be uploaded. That is, in this case as well, as in the above-described prior art, the user designates a point on the map and associates it with a predetermined digital camera image. The result of associating the map with the digital camera image is stored in the memory on the car navigation side in the first conventional example, and is stored in the server side or the user's personal computer in the second conventional example.
Therefore, there is a GPS camera that incorporates a GPS (Global Positioning System) in the camera, acquires shooting position information from the GPS, acquires a place name based on the position information, and records the shooting date and time and the shooting location together with the shot image ( Patent Document 1).
[Patent Document 1] Japanese Patent Laid-Open No. 7-64169
[Problems to be solved by the invention]
However, the GPS camera disclosed in Patent Document 1 requires a GPS function and also requires a place name information registration unit, which is expensive.
As described above, an object of the present invention is to associate position information of a shooting point with an image shot by a digital camera without a GPS function.
Another object of the present invention is to record captured image related information necessary for creating a drive album or the like on a recording medium of a digital camera.
[0005]
[Means for Solving the Problems]
According to the present invention, according to the present invention, the navigation device manages the position information of each point on the traveling locus and the traveling locus information including the passing time of each point, and is photographed with a digital camera with reference to the traveling locus information. By obtaining a point of the passage time closest to the date and time that is attached to the image and acquiring the photographed image related information including the position information of the point and writing it on the recording medium, Achieved.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic explanatory diagram of a method for writing captured image related information according to the present invention. Each captured image recorded on a recording medium (bridge medium such as a memory stick) 2 of the digital camera 1 is given a shooting date and time. On the other hand, the travel locus information from the departure point to the destination is recorded in the memory of the navigation device 3. This travel locus information includes position information of a point on the travel locus (a point for each predetermined travel distance or a point for each intersection) and the passage date and time of the point.
Therefore, the recording medium 2 is detached from the digital camera 1 and attached to the recording medium receiving portion of the navigation device 3, and the navigation device is requested to record captured image related information. The navigation device 3 shoots a point of the passing time that is earlier than the shooting date and closest to the shooting date and time based on the shooting date and time and the travel locus information of each shot image recorded in the recording medium 2 according to the request. It is regarded as a point, the position information (longitude and latitude) of the shooting point is acquired, the place name and the peripheral POI (Point of interest) are acquired from the database based on the position information, and these are recorded in association with the shot image Recorded on the medium 2.
[0007]
FIG. 2 is an explanatory diagram of acquisition of position information of shooting points. The shooting points are dropped off at points A ′, B ′, and C ′, and shots are taken with the digital camera at points A, B, and C, respectively. 2 is recorded.
Location information of each point (including points A ′, B ′, and C ′ that have come down to walk to the stop points A, B, and C) on the travel locus RRT from the departure point SP to the destination DP The time is stored in the memory of the navigation device as travel locus information. The navigation device 3 obtains a point on the locus of the closest passage time that is before the photographing date and time based on the photographing date and time of the image photographed at the point A and the traveling locus information. Referring to FIG. 3, the point on the corresponding trajectory is a point A ′ that is dropped to stop at the point A. Therefore, the photographed image related information including the position information (latitude and longitude: xa ′, ya ′) of the point A ′ is acquired and written into the recording medium 2. The captured image related information includes a place name of the point A ′, a peripheral POI (such as a sight, facility) near the point A ′, and peripheral map data.
As described above, the user can easily associate the position information, the point related information, and the photographed image comment information with the photographed image without performing the work of associating the map with the photographed image of the digital camera or inputting the related information.
[0008]
FIG. 4 shows a format example of image index information recorded on a memory stick, and a large size area (a + b) is allocated for each captured image as an image index. However, as the image index information, (1) image number, (2) camera data at the time of shooting image recording (ISO sensitivity, shutter speed, aperture, color correction,..., Shooting date, shooting time,. However, only this information is recorded on the recording medium, and the area b becomes an unused area.

FIG. 11 is a drive album creation process flow.
The memory stick 2 is attached to the memory stick receiving part of the personal computer 4 (step 201). Thereafter, the creation of an album is instructed (step 202). As a result, the personal computer 4 acquires information (news / weather photos, POI photos) necessary for creating the album via the Internet (step 203), and uses the acquired photos, captured image related information, and captured images as shown in FIG. Create an album table of contents and display it on the monitor. In this album contents, the predetermined photographing image 53a-53c _1, 53c ₂ is instructed, together to enlarge the photographed image, the position information of the imaging location, location name, neighboring POI information, indices required a peripheral map Information is displayed (step 204). If you want to see another captured image, return to the contents screen and select a predetermined captured image.
As described above, since the photographed image-related information is recorded together with the photographed image on the memory stick 2, the personal computer 4 can automatically create and display a drive album without any user instruction or operation.
