Description

  The present invention relates to a vehicle navigation apparatus configured to be able to transfer data to and from a memory in which image data taken by a digital camera is stored, and to add auxiliary information to the image data taken by the digital camera. The present invention relates to an image data processing apparatus that performs the processing, and a program that is executed by a computer that constitutes the image data processing apparatus.

In recent years, the memory capacity of digital cameras has increased, and the number of images that can be captured has increased. Therefore, if you try to organize the image data after continuing to shoot until the memory is full, a long period may have elapsed since the first shoot, and where each photo was taken It may take some time to organize.
One technique for dealing with the above problem is Patent Document 1. In this technology, a recording medium used for a digital camera is connected to a car navigation device, and for each piece of photo data, information on a point passing through the nearest date before the shooting date is recorded in association with the photo data. It is written on the medium. Therefore, when taking a picture with a digital camera in the middle of the drive, when organizing the pictures later, it is possible to grasp at which point in the drive each picture was taken.
Japanese Patent Laying-Open No. 2005-20511

However, as disclosed in Patent Document 1, if information on a point passing through the nearest date and time before the shooting date of the photo data is associated with the photo data, the image was actually shot at a timing unrelated to the drive. Even if a photo is part of it, everything is associated with the location on the drive. Therefore, there is a problem that the possibility of an error in correspondence with the point where the photograph was taken cannot be excluded.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle navigation apparatus and image data processing capable of more reliably performing correspondence between photographic data photographed by a digital camera and travel history. The present invention provides an apparatus and a program executed by a computer constituting the apparatus.

The “means other than the own vehicle” here refers to, for example, a bus, a train, and a passenger plane except for walking. In addition, the vehicle used when photographing with the digital camera is referred to as “own vehicle”, and includes other vehicles (automobile, motorcycle, bicycle).

  That is, if the user returns to the departure station or airport, for example, by using the moving means as described above, a considerable number of days may have elapsed during that time. Therefore, when the user organizes the image data, referring to the travel process time added to the image data, how many days it took to travel between the images taken at the same passage point. Can be clearly understood.

Yes. Depending on the accuracy, the position detector 3 may be constituted by only a part of the sensors 16 to 18 described above. Further, a steering rotation sensor, a wheel sensor of each rolling wheel, or the like may be used.

The map data input device 4 is a map data recording medium that records various data such as road map data, landmark data, map matching data, destination data (facility database), and table data for converting traffic information into road data. It is comprised by the drive device for reading data from. As the map data recording medium, a large-capacity storage medium such as a DVD is generally used, but a medium such as a memory card or a hard disk device may be used.
The road map data includes data such as road shape, road width, road name, signal, railroad crossing, building, various facilities, place name, terrain, etc., and for displaying the road map on the screen of the display device 7. Contains data. Destination data consists of information about transportation facilities such as stations, leisure facilities, accommodation facilities, public facilities, various stores such as retail stores, department stores, restaurants, residences, condominiums, and place names. The data includes data such as the telephone number, address, latitude and longitude, and data for displaying landmarks indicating facilities on the screen of the display device 7 on the road map. It is configured.

  The operation switch group 5 as input means is configured to include a mechanical switch provided in the vicinity of the screen of the display device 7 and a touch panel provided on the screen of the display device 7. The user (driver) uses this operation switch group 5 to input a destination, information necessary for searching for the destination (destination search condition), a passing point, and the like, an activation route, an activation point, and a display to be described later. Various commands for switching the screen and display mode of the apparatus 7 (map scale change, menu display selection, route search, route guidance start, current position correction, volume adjustment, etc.) are input. The remote controller 12 is provided with a plurality of operation switches, and various command signals are transmitted from the remote controller 12 to the control circuit 2 via the remote controller sensor 13 by the switch operation. Note that the operation switch group 5 and the remote controller 12 can cause the control circuit 2 to execute the same function by any operation.

  The external memory I / F 6 corresponds to a memory medium such as a flash memory card, for example. As for navigation, for example, the route data set by the control circuit 2 at the time of route guidance, the vehicle passed It is used for writing and storing route data and the like in a recording medium such as a memory card. Further, as described above, it is also used as an interface for performing data transfer with the memory medium 22 on which photographic data taken by the digital camera 21 is recorded.

  On the screen of the display device 7 (display means), a map around the position of the vehicle is displayed at various scales, and a current location mark (pointer) indicating the current position and the traveling direction of the vehicle is superimposed on the display. Is displayed. In addition, a route guidance screen is displayed when route guidance to the destination is executed. Furthermore, an input screen for inputting information necessary for the user to search for the destination, searching for the destination, and setting, various messages, and the like are also displayed.

  The voice recognition device 11 collates the voice inputted through the microphone 10 with the dictionary data for recognition stored therein, and recognizes the inputted voice. The voice controller 9 controls the voice recognition device 11 to output a voice recognition result to the control circuit 2 and outputs the recognized voice as a talkback via the speaker 8. Further, an audio output signal is output to the speaker 8 based on the audio output command from the control circuit 2. The sound output from the speaker 8 is a sound related to guidance, a sound related to operation explanation, the above talkback sound, or the like.

The microcomputer constituting the control circuit 2 includes a CPU, a memory (RAM, ROM, EEPROM, flash memory, etc.) 19, an I / O, and the like. When the CPU executes a program stored in the ROM (or flash memory), the control circuit 2 can perform destination setting means, route search means, display control means, route guidance means, passage route specification means, function control means, Functions as current position correction means. The function as the route search means is to automatically calculate a recommended travel route from the starting point (current position) of the vehicle to the destination. For example, the Dijkstra method is used.
The function as the route guidance means is to display a road map around the current location on the screen of the display device 7 so that it can move along the travel route, and to display a current location mark indicating the current position and traveling direction of the vehicle on the road map. This is a function for displaying images in a superimposed manner. In this case, the display of the current location moves on the map as the vehicle travels, and the map is scrolled according to the position of the vehicle. At this time, map matching is performed in which the current location of the vehicle is placed on the road.

  The memory 19 of the control circuit 2 stores vehicle travel history data as shown in FIG. The data contents include, for example, a route number (link ID), a travel date, a departure time, an arrival time, a destination, a departure place, a waypoint, fuel consumption, an average speed, a trajectory pointer, and the like for each travel route. Thus, the storage area of the travel locus data is shown. The travel locus data includes a point number, a point passage date and time, and point position information (longitude / latitude). Examples of the point include an intersection and a stop point.

Next, the operation of the present embodiment will be described with reference to FIGS. FIG. 4 shows an example of a stroke when the driver drives the vehicle, stops at each point, and moves while taking a picture with the digital camera 21. When the driver gets into the vehicle from the start point ST and starts moving and stops at the point A ′, the digital camera 21 takes a picture at the point A near the point A ′. Subsequently, the driver moves to the inn B ′ by the vehicle, stops, and takes a picture at a point B near the point B ′.
The next day, the driver strolls around the inn B 'on foot and takes a picture with the digital camera 21 at the point B2, and then departs from the inn B' by vehicle the next day. When the vehicle stops at the point C ′, the digital camera 21 captures an image at the point C in the vicinity of the point C ′, and then the vehicle moves by the vehicle and returns to the stop point SP. The data of the photograph taken during the above process is stored in the memory medium 22 accommodated in the digital camera 21 together with the shooting date and time data.

  FIG. 5 is a flowchart showing the processing contents performed mainly by the control circuit 2 when the memory medium 22 is connected to the external memory I / F 6 of the vehicle navigation apparatus 1. First, when the user operates the operation switch group 5 to request the control circuit 2 to write shooting-related information (step S1), the control circuit 2 sets each variable “i, J, k ”is initialized to“ 1 ”(step S2). Then, the shooting date / time data attached to the i-th image data is acquired from the memory medium 22 (step S3).

  Subsequently, when the control circuit 2 refers to the travel history data of the own vehicle and finds a point that has passed the closest date and time before the shooting date and time acquired in step S3 (step S4), the control circuit 2 acquires position information of the passing point. (Step S5). Here, FIG. 6 shows the processing contents in step S5. The control circuit 2 determines whether or not the passing point is a specific point that may be moved by means other than the own vehicle, such as a parking lot at home, a station, or an airport (step S21). .

  Here, “means other than the host vehicle” in step S21 is, for example, a bus, a train, or a passenger plane excluding walking. In addition, the vehicle used when taking a picture with the digital camera 21 is referred to as “own vehicle”, and includes other vehicles (automobiles, motorcycles, bicycles) (for example, when the specific point is at home). And when a passage point corresponds to either of them ("YES"), the point information is memorize | stored with the flag etc. which show that it is said specific point (step S22). On the other hand, when the passing point is other than the specific point (“NO”), the information about the other points is stored as it is (step S22a).

  Again referring to FIG. When the position information of the passing point is acquired in step S5, the control circuit 2 compares the i-th image information with the (i-1) -th image information (step S6). Here, FIG. 7 shows the processing contents in step S6. First, the control circuit 2 determines whether or not the variable i is greater than “1” (step S23). If the variable i is greater than “1” (“YES”), the i-th and (i−1) -th image data are determined. The position information added to is compared (step S24). If the position information of the two is “different”, the variable j for grouping the shooting points is incremented (step S25). The variable k is also initialized to “1” here.

  On the other hand, if the position information of both is “same” in step S24, the shooting date and time of both are further compared (step S26). If the shooting date is “same”, the process returns to the main routine as it is, and if the shooting date is “different”, the variable k for sub-grouping image data at the same point with a different date is incremented (step S27).

Again referring to FIG. When the i-th and (i-1) -th image information is compared in step S6, the control circuit 2 determines that the difference between the shooting date and time of the i-th image data and the passage date and time of the passing point added to the data is elapsed. Time information is obtained (step S7). Then, the position information of the most recent passing point, the elapsed time obtained in step S7, the point group number j , and the subgroup number k are added to the i-th image data, and are written and stored in the work area of the memory 19 ( Step S8). Then, it is determined whether or not the above processing has been performed on all image data in the memory medium 22 (step S9). If there is remaining image data ("NO"), the variable i is incremented (step S10). Return to step S3.

  On the other hand, if all the image data has been processed in step S9 ("YES"), the related information corresponding to each image data is read and written to the memory medium 22 (step S11). FIG. 8 shows details of the processing in step S11. When the control circuit 2 initializes the group variable i to “1” (step S31), it reads the point group number j and the subgroup number k for the i-th image data (step S32). If the variable i is “2” or more (step S33, “YES”), it is determined whether the group numbers j and k of the i-th image data and the previous image data are the same. (Step S34).

  In step S34, if the group numbers j and k of the i-th and (i-1) -th image data are both the same ("YES"), the control circuit 2 determines the passing point of the group and the group. Based on the longest elapsed time among the image data to which it belongs, the map data input device 4 is searched for a potential drop-in point. And the point information is memorize | stored in the memory medium 22 as related information (step S35). The longest elapsed time may be obtained in the process of step S35 or, for example, after the determination of “YES” in step S9, it may be obtained all at once before the execution of step S11.

  Here, a specific example of the process in step S35 will be described with reference to FIG. For example, it is assumed that the movable range when the passing point of the same group is “XX parking area” and the longest elapsed time is 5 minutes is within the circumference shown in FIG. In this case, for example, “XX park”, “XX temple”, “XX shrine” and the like are points that are likely to drop in and are located in the movable range. Therefore, in step S35, such point information is added to the image data. In step S34, if either the spot group number j or the subgroup number k is different ("NO"), the process proceeds to step S38.

In subsequent step S36, it is determined whether or not the passing point added to the image data is a specific point as determined in step S21 of FIG. 6, and if it is a specific point ("YES"), the same point group number The travel process days that are the difference between the oldest shooting date and time and the latest shooting date and time are obtained, and the travel day information is added to the image data of the same spot group number and stored in the memory medium 22. That is, when the user returns to the departure station or airport using the above-mentioned transportation means, for example, a considerable number of days may have elapsed during that time. Add information about the estimated number of days.
Then, in step S38, the same determination as in step S9 is performed. If there is remaining image data ("NO"), the variable i is incremented (step S19), and the process returns to step S32. ("YES"), the process returns to the main routine in FIG.

  FIG. 10 shows a format example of related information added to the image data stored in the memory medium 22 as a result of the above processing. For each image data, an area for storing various related information is secured, and when the digital camera 21 captures an image, the image number and camera data (ISO sensitivity, shutter when recording the captured image) are recorded. The speed, aperture, color correction, shooting date and time, etc. are stored, and since there are some unused areas, related information is stored in the unused areas, that is, position information (latitude) of passing points. , Longitude), point group information, subgroup information, drop-in point information, travel process days / hours information, and the like.

As described above, according to the present embodiment, the control circuit 2 of the vehicular navigation apparatus 1 includes the shooting date / time data accompanying the image data shot by the digital camera 21 stored in the memory medium 22 and the control circuit 2 itself. By comparing the passage date and time data associated with each point in the travel history stored in the memory 19, the passage point information corresponding to the nearest passage date and time before the photographing date and time, and from the passage date and time to the photographing date and time. The elapsed time data is added to the image data and stored in the memory medium 22.
Therefore, for example, when the user takes the data of the memory medium 22 into a personal computer or the like and organizes the image data, the passage point added to the image data is compared with the elapsed time data up to the shooting date and time. This makes it possible to appropriately determine whether or not the image is actually taken in the vicinity of the passing point.

Then, the control circuit 2 adds the group information of the points for classifying the image data having the same point information to the same group to each image data and stores them in the memory medium 22, so that the classification processing of the image data is performed on the point group information. Can be done in more detail based on. The control circuit 2 also adds subgroup information that classifies image data with the same point group information with different shooting dates into subgroups, so that, for example, the user stayed at the destination In such a case, it is possible to classify the image data belonging to the same point group into different subgroups and to facilitate their arrangement.

  Furthermore, the control circuit 2 searches the map data input unit 4 for a point located within the movable range from the passing point of the group and the longest elapsed time for the image data group having the same point group information and subgroup information. Then, the searched point information is added to the image data of the same group and stored in the memory medium 22. Therefore, when the user organizes the image data, the point where the image is actually captured can be more reliably specified by referring to the stop point information added to the image data.

  In addition, when the point information added to the image data indicates a specific point where there is a possibility of using a means other than the own vehicle, the control circuit 2 displays the date / time data attached to the image data belonging to the same group. Among them, the travel process time is calculated based on the oldest date and the latest date, and the time information is added to the image data of the same group and stored in the memory medium 22. Therefore, when the user organizes the image data, referring to the travel process time attached to the image data, how many days it took to travel between images taken at the same specific point. Can be clearly understood.
