On the other hand, cameras have been reduced in size and weight, and examples of use in cameras incorporated in pocket computers have emerged. However, if the recorded image captured by the camera cannot be easily searched for and reproduced later, the usefulness is poor. For example, it is preferable that attribute information relating to shooting, such as shooting location, shooting date and time, and shooting content, be added to the recorded image, and the recorded image can be searched using the attribute information.

[0003] Techniques for providing audio and image information in association with a map have already been proposed, but there is still room for improvement in the following respects.

In the techniques of (b) and (b), a captured image and additional information are displayed by a captured image reproducing device having a search function separate from the imaging device, and a predetermined image is operated by operating a keyboard, a mouse, or the like. Is selected. The additional information displayed on the screen of the separate player is not a map but characters, and there is a problem that an image cannot be searched while referring to the map. Further, in the technique (c), a predetermined symbol is displayed on a map, and it is indicated that an image is taken at that point. However, in order to know the image more specifically, Required the user to perform certain operations. Further, the technique (c) has a problem that the processing procedure executed in the apparatus is complicated and the operation by the user is complicated.

An object of the present invention is to record a user's desired voice and image information in association with a shooting location without complicated operations and in an organized processing procedure, An object of the present invention is to provide a map display device capable of retrieving voice and image information.

Each device is connected by an internal bus 6.

The present invention is characterized in that it has a recording / reproducing processing capability that can be used by a user as needed. Hereinafter, each processing apparatus will be described in detail.

The map image generating device 2 creates image data corresponding to a map image of a designated area. As will be described later, the map image generation device 2 receives the display area and the display output destination address from the control device 5, and outputs the created map image image data to a location specified by the display output destination address.

As shown in FIG. 1, the map image generating device 2
Has an image data drawing unit 16 and a map data storage unit 17. The map data storage unit 17 stores map data managed for each area, and the image data drawing unit 16 reads out the map data of the area specified by the control device 5. The image data drawing unit 16 generates image data of a map image from the read map data, and outputs this to a predetermined destination (apparatus).

Generally, a value called a mesh code defined based on latitude and longitude is used as a value indicating an area.
In the present embodiment, a mesh code conforming to the JIS standard is used. As the map data, data created by the Japan Digital Map Data Association or the Navigation Research Society is used.

Each time the position detecting device 3 receives a request from the control device 5 by using the GPS, the position detecting device 3 can obtain the current position in the form of latitude and longitude values. Position detection device 3
Has a GPS receiver 18, a timer 18a, and a buffer memory 18b. The current position data continuously transmitted from the GPS satellites is transmitted to the GPS receiver 18 by the GPS receiver 18.
At regular intervals, which are continuously received and counted by the timer 18a, the received data is stored in the buffer memory 18b. The current position data stored in the buffer memory 18b is updated at regular intervals counted by the timer 18a. This current position data can be read out by the control device 5 at any time.

Next, the audio / video processing apparatus 1 performs photographing and recording / playback processing, and includes a camera 10, a microphone 11, an AD conversion unit 12, a file handler 13, a recorded file storage unit 14, and a timer 15. I have.

The audio-video processing apparatus 1 operates according to the six commands shown in FIG. These instructions are provided from a control device 5 described later. In addition, some of the instructions include an argument accompanying an argument and an instruction requesting a return value. FIG.
As shown in (a), one instruction is defined by an instruction name, and in some cases, three items, an argument and a return value. The instruction name includes an instruction code expressed in a binary number in an actual device. used. In FIG. 2A,
The item indicated by "-" indicates that it is undefined. Even if a value is given to this item, it has no meaning and is ignored in the processing.

The operation of the audio-video processing device 1 will be described below in the order of the commands shown in FIG. It is assumed that the image handled here is a moving image.

When the audio image processing apparatus 1 receives a recording preparation command from the control apparatus 5 via the internal bus 6, the image signal and the audio signal obtained by the camera 10 and the microphone 11 are converted into analog signals by the AD converter 12. The data is converted into digital data, and the obtained data is output to a location indicated by the camera image output destination address which is an argument of the recording preparation instruction. In this device, the output destination address of the camera image is the drawing memory 31 in the interface device 4. Therefore, an image captured by the camera 10 of the device can be displayed on the screen of the liquid crystal display 33. File Handler 1
Reference numeral 3 designates an ID number for creating a recording file in the recording file storage unit 14 and uniquely specifying the recording file. This ID number is returned to the control device 5 via the internal bus 6 as a return value.

Next, when the audio / video processing apparatus 1 accepts the recording start command, the image data and the audio data digitized by the AD converter 12 are synchronized with the signal from the timer 15 and the recording file is transmitted by the file handler 13. It is stored in a recording file secured in a predetermined area of the storage unit 14. That is, the image and the sound currently captured by the camera 10 and the microphone 11 are recorded.

The timer 15 gives a timing signal to the file handler 13 every 1/30 second, for example, so that the file handler 13 converts the digitized image data and audio data every 1/30 second. Are stored in the recording file of the recording file storage unit 14. This operation is continued until the audio-video processing device 1 accepts the recording stop command or until the recording file becomes full.

When the image data and the audio data are stored in the recording file of the recording file storage unit 14, they are stored as one file in a bundled form, and the storage format is a format called MPEG or RIFF. There is something called. Generally, the stored image data and audio data are handled in one unit called a frame, and in the present invention, are stored one frame at a time every 1/30 second. The set of frames recorded in chronological order in this way is called a recorded file in the present invention.

When receiving the recording stop command, the audio-video processing apparatus 1 stops the above-mentioned recording processing. If it has already stopped, ignore this instruction.

Next, when the audio-video processing apparatus 1 receives the reproduction start command, the recording file ID passed as an argument
On the basis of the number, the file handler 13 specifies the recorded file with the ID number in the recorded file storage unit 14, and synchronizes with the signal given from the timer 15,
For example, every 1/30 second, the recording file is sequentially read from the first frame, and audio data and image data are extracted from this frame. Each of these data is output to a predetermined location based on the image output destination address included in the argument. This operation is continued until the audio-video processing device 1 accepts the reproduction stop command or reads all the frames from the recorded file.

When receiving the reproduction stop command, the audio-video processing apparatus 1 stops the reproduction processing. If it has already stopped, this command is ignored.

Finally, when the audio-video processing apparatus 1 accepts the image acquisition command, the recording file I passed as an argument
Based on the D number, the file handler 13 specifies the recording file with the ID number in the recording file storage unit 14, reads the first frame of the specified recording file, and uses the image data of the first frame as an argument. Output to a predetermined location based on the included image output destination address.
If the recording file corresponding to the passed recording file ID number cannot be found, this command is ignored.

The audio-video processing device 1 operates based on the commands shown in FIG. 2A, and these commands are all given by the control device 5.

Next, the interface device 4 according to the present embodiment will be described. The interface device 4 provides a user with operation input means, and superimposes a map image based on image data generated by the map image generation device 2 with a current position detected by the position detection device 3 and the like. ,
It is displayed on the screen of the liquid crystal display 33. Further, the interface device 4 reproduces a sound, a captured image, or a stored sound or image obtained by the sound image processing device 1.

In this embodiment, the interface device 4 is provided with a GUI (Graphical User I).
interface) processing unit 30, drawing memory 31, DA
It has a speaker 32 having a converter and an amplifier and a liquid crystal display 33 with a touch panel.

The drawing memory 31 temporarily stores image data of an image displayed on the liquid crystal display 33 such as image data of a map image, a current position, a photographing point, reproduction output of photographed video and recording information, and the like. Is output to the liquid crystal display 33 with a touch panel.

The liquid crystal display 33 with a touch panel is provided with a touch panel on the front.
With this touch panel, an input from a user can be accepted. More specifically, the input is realized by displaying the operation buttons and the photographing point on the liquid crystal display, and pressing the user on the display. Which request is made by pressing the panel can be uniquely specified by the operation state of the map display device described later and the coordinates of the pressed position.

The speaker 32 includes a D / A converter for converting a digital signal into an analog signal and an amplifier for amplifying the analog signal to a predetermined level, and can reproduce a sound based on the sound data.

By the way, the map display device according to the present embodiment waits for various operation states, and
Restricts the commands that can be input according to each state.
By doing so, it is possible to provide the user with an orderly operation input procedure, and at the same time, prevent the map display device from erroneously interpreting the command. Therefore, first, a command that can be input by the map display device via the interface device 4 will be described, and then an operation state that the map display device can adopt and a state transition thereof will be described.

FIG. 2B is a diagram showing commands that can be input in the map display device according to the present embodiment. The operation buttons corresponding to the first to seventh commands shown in FIG.
The user can input a desired request by pressing these buttons.

In the interface device 4, the current operation state is stored in the GUI processing unit 30, and the commands that can be input by the user are limited according to each operation state, thereby providing an orderly operation procedure. . Further, the operation of the interface device 4 merely detects what the operation request is in accordance with the pressing of the operation button and transfers the command to the control device 5.

Therefore, the actual processing is executed by the control device 5.

The first to seventh operation instructions shown in FIG. 2B are composed of three items: an instruction code name, an argument necessary for executing the instruction, and a return value indicating the result of the instruction. Defined. The instruction code name is expressed in a binary number in an actual device.

The operation instructions will be described below in numerical order according to the instruction list shown in FIG. The item indicated by "-" in the instruction list indicates that the item is undefined. Even if a value is given to this item, it has no meaning and is ignored in the processing.

The first "StandByRcd" command requests the map display device to prepare for shooting, while the fifth "StandByPly" command requests the map display device to prepare for reproduction. is there.

As will be described later, the map display device according to the present embodiment has two operation modes, a photographing mode and a map mode, which are mutually exclusive.
"StandByRcd" instruction and "StandBy"
The “Ply” command indicates a request to switch to the operation mode of the other party. For example, "StandByRc
d) command is issued when the map display device is in the map mode.
A request to switch from map mode to shooting mode,
On the other hand, the “StandByPly” command means a request to switch from the shooting mode to the map mode when the map display device is in the shooting mode.

The second “RecordStr” instruction and the third “RecordStp” instruction are respectively
A recording start request and a recording stop request are shown, and the fourth “R
The "egistMap" command requests that the recorded audio data and image data be stored in association with the shooting location or the shooting time, and displays the shooting location on a map.

The sixth "PlayBackMovie"
The command requests reproduction of the recording information corresponding to the display coordinates by designating the display coordinates of the photographing point displayed on the map as an argument. Also, the seventh “Stop
The "Movie" command requests the end of the reproduction process.

Next, the state transition of the map display device according to the present embodiment will be described with reference to FIG. As shown in FIG. 3, the operation state of the map display device is roughly divided into two operation states of a map mode and a photographing mode, and the map mode further includes a reproduction request waiting state and a reproduction state.
There are two operating states. Further, the photographing mode includes a recording request waiting state and a recording state, and the map display device cannot be in two states at the same time. These two modes and four states limit the commands that can be input, respectively, and transition to a predetermined mode or state when the command is received.

For example, assuming that the operation state of the map display device is a recording request waiting state in the edit mode, the commands that can be input here are the “RegistMap” command and the “Recor
dStr ”instruction or“ StandByPly ”instruction.

When the “RegistMap” instruction is accepted, the recording request wait state is resumed. On the other hand, when the “RecordStr” instruction is accepted,
Transition to the recording state. The “StandByPly” command is a command that can be input in a recording request waiting state or a recording state. When this command is accepted, the state transits to a map mode reproduction request waiting state.

In the recording state, "RecordSt"
A "p" command or a "StandByPly" command can be input. When the “RecordStp” command is accepted, the state transits to the recording request waiting state, and on the other hand,
When the “StandByPly” command is accepted, the state transits to the map mode reproduction request waiting state.

On the other hand, when the state transits to the map mode playback request waiting state by the “StandByPly” command, in this map mode playback request waiting state,
“PlayBackMovie” instruction or “Stan
"dByRcd" command can be input. "PlayBa
If the “ckMovie” command is accepted, the state transits to the playback state, and if the “StandByRcd” command is accepted, the state transits to the recording mode waiting state in the photographing mode. When the playback state is changed by the “PlayBackMovie” command, a “StopMovie” command or a “StandByRcd” command can be input.
When the “StopMovie” command is accepted, the state transits to a reproduction request waiting state, and when the “StandByRcd” command is accepted, the state transits to a recording request waiting state in the shooting mode.

As described above, in the map display device, the map mode, the photographing mode, and the four modes included therein are included.
By defining two operation states and clarifying the commands accepted in each state, it is possible to distinguish between the reproduction operation and the recording operation, and it is possible to provide a user with an orderly operation input procedure. At the same time, it is possible to prevent the map display device from erroneously interpreting the command, and to provide an effective interface means.

The control processing for these inputs is as follows:
It is executed in the GUI processing unit 30 provided in the interface device 4. Hereinafter, the GUI processing unit 30 will be described.

The GUI processing unit 30 includes the liquid crystal display 3
Operation buttons are displayed on the screen of No. 3 and the operation buttons pressed via the touch panel are detected, and the corresponding operation requests are transferred to the control device 5. The displayed operation buttons substantially correspond to the commands shown in FIG. That is, the "map" button, the "shooting" button, the "playback start" button, the "playback stop" button, the "recording start" button, and the "recording stop" button included in the operation buttons include a "StandByPly" command, StandRe
c "instruction," PlayBackMovie "instruction," S
It corresponds to the “topMovie” instruction, the “RecordStr” instruction, and the “RecordStp” instruction.

The display coordinates of the map, the coordinates of the image display at the time of shooting or reproduction, and the display coordinates of the buttons are determined by the GUI processing unit 30.
In accordance with the display coordinate data stored in the storage unit 30a provided in the inside. The display coordinate data is, for example, as shown in FIG.
It is shown as follows. That is, as shown in FIG. 4, the display positions of the six buttons of the “map” button, the “shooting” button, the “playback start” button, the “playback stop” button, the “recording start” button, and the “recording stop” button are changed. Defined. Here, assuming that the displayable range of the liquid crystal display 33 is 640 × 480 (dots), the “map” button corresponds to the point corresponding to the coordinates (10, 10) and the coordinates (2
It is displayed as a rectangle having the point corresponding to (0, 20) at the vertex. Further, the GUI processing unit 30 can determine which button area includes the position pressed via the touch panel on the screen of the liquid crystal display 33 based on the display position data.

However, since the coordinate data of the photographing point is dynamic, it is not stored in the storage unit 30a, but is stored in the photographing information storage unit 24 provided in the control device 5. Therefore, the GU determines whether the touched position is a shooting point.
It cannot be detected by the I processing unit 30, and this is left to the control device 5.

The GUI processing unit 30 has a variable for storing an operation state where the map display device is currently placed.
These variables include a variable for recording the current operation mode called ModeFlag, a variable PlayFlag for storing either a playback request waiting state or a playback state in the map mode, a recording request waiting state in the shooting mode, or Variable R for storing whether or not recording is in progress
ecFlag.

Hereinafter, the operation of the GUI processing unit 30 will be described in more detail. FIG. 5 and FIG. 6 are flowcharts showing the processing of the GUI processing unit 30.

When the power is turned on, the GUI processing unit 3
0 is started, and the processing is sequentially executed from step 501. The GUI processing unit 30 sends “S” to the control device 5.
tanbyPly "instruction and ModeFlag
Is set to a map (map mode), PlayFlag is set to Off, and the initial state of the map display device is set to a reproduction request waiting state in the map mode (step 502).

Next, it is detected whether or not the touch panel provided on the liquid crystal display 33 has been pressed (step 503). If it is determined as NO (NO) in step 503, it is detected again whether or not the pressing is performed, and the process of step 503 is repeated until the pressing is detected. On the other hand, if it is determined that the answer is YES in step 503, the process proceeds to step 504.
Proceed to.

In step 504, it is determined with reference to the display coordinate data stored in the storage unit 30a in the GUI processing unit 30 whether or not the pressed button is the "shooting" button. If the determination at step 504 is affirmative (YES), the map display device transitions to the photographing mode, and processing necessary for photographing is executed. This processing will be described later.

On the other hand, if it is determined NO (NO) in step 504, that is, if it is determined that the pressed button is not the “shooting” button, the current operation state is the reproduction request waiting state. Is determined (step 505). More specifically, in this step 505, it is sufficient to check whether or not PlayFlag is Off. If PlayFlag has been set to Off, the process proceeds to step 507, and issues “PlayBackMovie”, which is a moving image playback command, to the control device 5. At this time, "PlayBackMov
The “ie” command is transmitted to the control device 5 with the coordinate value of the pressed position. The control device 5 determines whether or not the received coordinate value is on the shooting location. The result of this determination is reflected in the return value of the “PlayBackMovie” instruction. In other words, a return value indicating success is returned if there is an imaging point corresponding to the coordinate value of the pressed position, and a return value indicating failure if not.

Next, at step 508, "Pl
The return value of the "ayBackMovie" instruction is examined,
When notified that the “PlayBackMovie” command has succeeded, the processing executed by the control device 5 or the like performs the reproduction processing of the image file corresponding to the coordinate value of the pressed position. Therefore, step 50
At Step 9, PlayFlag is set to On, and it is recorded that the operation state of the map display device has transitioned to the reproduction state.
Thereafter, the process returns to step 503 and waits for the next input.

On the other hand, “PlayBackMov
If it is notified that the "ie" command has failed, it means that there is no image file corresponding to the coordinate value of the pressed position, and the reproduction process is not performed. That is,
The touch operation from the user is ignored, and the process returns to step 503 to wait for the next input.

If it is determined NO (NO) in step 505, the pressed button is set to "reproduction stop".
It is determined whether the button is a button (step 506).
The pressed button is a “stop playback” button, and
If the PlayFlag is On (Yes in step 506), “StopMobi
The "e" command is transmitted to the control device 5, and the reproduction process ends. As a result, the operation state changes to a reproduction request waiting state, so that PlayFlag is set to Off to record this (Step 510). Then, step 50
Return to 3 and wait for the next input.

On the other hand, if the pressed button is not the “reproduction stop” button, or if PlayFlag is off and the reproduction request is awaiting, the process returns to step 503 without doing anything and waits for the next input. .

Next, at step 503, the answer is yes (Y
If ES) is determined, that is, if the pressed button is determined to be the “photographing” button, an explanation will be added.

When the “photograph” button is pressed, G
The UI processing unit 30 switches the operation state from the map mode to the shooting mode. The processing for this is performed in step 51
This corresponds to steps 2 to 514. First, step 5
At 12, the value of PlayFlag is checked. If On
If it is set to, it is considered that the reproduction process is currently being performed, and the control device 5 is requested to perform the reproduction stop process in step 513. The actual playback stop processing is performed by the controller 5
And so on. In addition, since the state is switched to the reproduction request waiting state by the request for the reproduction stop processing, PlayFl
The value of ag is set to Off, and the current state is recorded. Next, in step 514, “StandByRec”
An instruction is issued to the control device 5, the operation state is switched from the map mode to the photographing mode, the value of ModeFlag is updated to photographing, and the state is recorded. Therefore, the subsequent input is performed in the shooting mode.

In step 520 of FIG. 6, it is detected whether or not the touch panel on liquid crystal display 33 has been pressed. No in this step 520 (NO)
If it is determined that the touch panel has been pressed again, it is detected whether or not the touch panel has been pressed.

In step 521, it is determined whether or not the pressed button is the "map" button by referring to the display coordinate data stored in the storage device 30a of the GUI processing unit 30. If the pressed button is the "map" button, the map display device transitions to the map mode in the processing from step 530 onward, as described later, and processes necessary for photographing are performed.

On the other hand, if the determination in step 521 is NO (NO), it is determined whether the coordinate value of the pressed button is that of the “recording start” button. As a result, when it is determined that the “recording start” button has been pressed and RecFlag is Off (Yes in step 522),
The “RecordStr” command is transmitted to the control device 5,
Recording processing is started.

As a result, the operation state changes to the recording state, so that RecFlag is set to On in order to record this (Step 525), and thereafter, the processing returns to Step 520 and waits for the next input.
