Minutes 00 seconds, Photo 2 was taken at time 07:16:15, Audio 1 was recorded at time 07:17:10, and Photo 3 was taken at 07:17:50. Has been taken to.

FIG. 6 shows an image / audio output device 20 to which the present invention is applied.

The image / audio output device 20 is applicable to a so-called personal computer. The image / audio output device 20 uses the locus data recorded on the first recording medium, the image and / or the audio recorded on the second recording medium, the time data thereof, and the like to generate an image and / or an image. The voice is associated with the position on the map.

Specifically, the image / audio output device 20
Is a ROM 21 storing a control program, and a CPU 22 controlling each circuit according to the control program.

A ROM drive 28 and a communication circuit 29 for transmitting and receiving data to and from the outside.

The third recording medium 26 includes the locus recording device 1
The locus data similar to the first recording medium used in (1) is recorded. That is, the third recording medium 26 is
It may be the same as the first recording medium used in the locus recording device 1. Further, the third recording medium 26
The above-mentioned locus data may be recorded from the locus recording device 1 via a communication line such as the Internet or the communication circuit 29.

The fourth recording medium 27 records the same image data and / or audio data as the second recording medium used in the image / audio recording device 10 and the time data. That is, the fourth recording medium 27 may be the same as the second recording medium used in the image / audio recording device 10. Also, the fourth recording medium 27
The above-mentioned locus data may be recorded from the locus recording device 1 via a communication line such as the Internet or the communication circuit 29.

In the image / audio output device 20, C
Based on the trajectory data recorded on the third recording medium 26, the PU 22 approximates the trajectory moved by the user with a broken line as ABCD-D-, as shown in FIG. can do.

At this time, the CPU 22 reads out time data indicating the time when the image data was recorded for the photograph 1 recorded on the fourth recording medium 27. The time data for Photo 1 is “07:16:00”. This time is the same as the time at point C. Therefore, CPU
A monitor 22 displays a map from the map data read from the CD-ROM drive 28 on the monitor 24, and associates the image of the photograph 1 with the point C so that the monitor 24
To be displayed.

Thus, the image of the photograph 1 is displayed in association with the position on the map, so that the user
The captured image and its position can be easily recognized.

Next, the CPU 22 determines that the photograph 2
The image data and the time data are read from the fourth recording medium 27. The time data for Photo 2 is “07:01
6 minutes and 15 seconds ". This time corresponds to the time “07:16:00” at the point C and the time “07:16” at the point D.
Minutes 30 seconds ".

Based on the position and time of the point C and the point D, the CPU 22 assumes that the user is moving at a constant speed during the period, and complements the point C and the point D with a straight line.
The midpoint between them is calculated, and this point is set as the position where the photograph 2 was taken. Thereby, the CPU 22 sets the intermediate point between the CDs as the position where the photograph 2 was taken, as shown in FIG. 7, for example.
The image data of the photograph 2 is displayed on the monitor 24, for example, in association with the intermediate point between the CDs.

Since the time of the voice 1 is "07:17:10", the CPU 22 interpolates between EFs before and after the time as shown in FIG.
The position where the sound 1 was recorded is calculated by internally dividing the weight into 2 and performing weighting. Thus, the CPU 22 specifies the position on the monitor 24 where the sound 1 was recorded on the map, and outputs the sound from the speaker 25.

As described above, according to the image / audio output device 20 to which the present invention is applied, the trajectory data recorded in the image / audio recording device 10 and the image / audio output device 20
The image and / or audio and the time data recorded in the above can be output in association with each other.

In the image / audio output device 20,
Many image / audio recording devices 10 without a position measuring mechanism
By comparing the timestamp of the image or sound object recorded in, it is possible to identify the position at which it was recorded, so that the width of the devices and objects that can use it can be increased. Can be spread.

The object whose recording position is specified is often associated with a map displayed on a personal computer or the like, so that a new information presentation scene can be provided to the user. At this time, the image / audio output device 20 can immediately arrange a large number of images captured by the image / audio recording device 10 on a map on the monitor 24.

Further, when a moving image is photographed by the camera unit 11 of the image / audio recording device 10, the image / audio output device 20 moves the position on the map corresponding to the reproduced scene every time the image is reproduced. Can also be displayed.

The processing in the image / audio output device 20 as described above is performed by installing the control program from a recording medium on which a predetermined control program is recorded in an information processing apparatus such as a personal computer. You may.

The present invention is not limited to the above-described embodiment, and for example, the following design changes can be made.

For example, in the present embodiment, the case where GPS is used for the positioning system has been described. However, the present invention is not limited to this, and the latitude and longitude may be measured by other methods.

Although the latitude and longitude are measured for each point every 30 seconds, for example, after measuring the latitude and longitude for a certain point, for the other points, only the difference between the latitude and longitude with respect to the one point is measured. May be measured,
At the same time, the altitude may be recorded.

In the trajectory recording device 1 described above, if the interval between the recording times of latitude and longitude is shortened, a large-capacity first recording medium is required. On the other hand, if the recording time interval is lengthened, the first recording medium does not need to have a large capacity, but only a rough trajectory can be obtained. Therefore, if the vector including the speed and the direction is also recorded, the information amount can be efficiently compressed when there is no significant change in the moving speed or the direction.

In the present embodiment, the case where an image or a sound is used as an object has been described as an example.
The present invention is not limited to this. That is,
Objects include text data input from the keyboard, characters and pictures handwritten on the touch panel,
The control program may be a predetermined control program obtained through broadcasting or communication, various kinds of observation data recorded continuously or at points, or the like, and is not particularly limited as long as it is associated with position information.

[0046]

As described above in detail, according to the object output device, the object output method, and the recording medium recording the object output control program according to the present invention, the time information recorded on the second recording medium can be obtained. The position at the indicated time is calculated based on the trajectory data recorded on the first recording medium, the calculated position is displayed, and the object recorded on the second recording medium is associated with the calculated position. By outputting, even when the trajectory data and the object are separately recorded, they can be easily associated with each other.

That is, it is possible to determine the position later only by checking the time stamp with respect to the objects recorded by many recording devices not provided with the position measuring mechanism. The range of devices and objects that can be used can be greatly expanded.
