Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic map display device that displays electronic map information, a navigation device that uses electronic map information, and a recording medium.
[0002]
[Prior art]
In recent years, map information has been digitized and can be displayed and used on a screen of a personal computer or the like. In a navigation device or the like, digitized map information is used and the current position, travel route, and the like are superimposed on a map and displayed on a monitor.
[0003]
In such electronic map information, for example, landmarks (landmarks) such as government offices, government offices, hospitals, other buildings, companies, stores, etc. are often displayed on the electronic map. Furthermore, on the user side, for example, position information of a specific place such as a store, company, various facilities, acquaintance's house, etc. is registered, and the position can be displayed on an electronic map by a so-called symbol mark or the like. There are also things.
[0004]
For example, in a navigation apparatus, various types of symbol marks such as a dining facility, a tourist facility, and a leisure facility are stored in advance. More specifically, for example, there are baseball symbol mark M1, golf symbol mark M2, tennis symbol mark M3 and the like as symbol marks for leisure (sports) facilities, as shown in FIG.
The user side selects a symbol mark that symbolizes the target location from the list of symbol marks, and registers it at an arbitrary position on the electronic map. The symbol mark registered in this way is displayed on the electronic map on the navigation screen, and the presence, position, and type of the set target can be recognized at a glance, thereby improving the visibility of the navigation device. Yes. These symbol marks can be improved in operability when the user sets a destination, for example.
[0005]
[Problems to be solved by the invention]
However, conventionally, a symbol mark prepared (stored) in advance in an electronic map display device, a navigation device, or the like merely represents a “type” of a target. Therefore, for example, when a golf course is registered with the symbol mark M1, all the registered golf courses are displayed with the same symbol mark M1, and it is difficult to identify the golf course.
For this reason, a plurality of symbol marks may be prepared for one “type”. For example, as shown in FIG. 9, a plurality of symbol marks M4, M5, and M6 are prepared as “human face” symbol marks. This makes it possible to use these symbol marks M4, M5, M6 for “acquaintance's house”, for example, and this may facilitate identification, but in practice the number of marks that can be used is Of course, it is limited, and it is difficult to recognize at a glance which symbol mark (for example, the symbol mark M5) indicates which person.
Thus, in the current situation, it has not always been said that the conventional form of use of symbol marks is good in recognition and usability.
[0006]
The present invention has been made based on such a technical problem, and an object thereof is to provide an electronic map display device, a navigation device, and a recording medium that are easier to recognize and more convenient to use.
[0007]

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
FIG. 1 is a diagram for explaining an overall system configuration of a navigation device (electronic map display device) according to the present embodiment. In this figure, reference numeral 1 is an arithmetic processing unit (image data fetching means) that controls the entire navigation device, 2 is a positioning unit that measures its own position, 3 is a remote controller as operation means for the navigation device, and 4 is a remote controller. 3 is a receiving unit for receiving operation information from 3, 5 is a storage unit (symbol mark storage unit) composed of a non-volatile memory such as a hard disk drive or flash memory, and 6 is a display unit (image display unit, display unit) such as a monitor. is there.
[0014]
Here, the arithmetic processing unit 1 includes a CPU 7 that controls the whole, a ROM 8 that stores predetermined programs, a RAM 9 that stores various data, the positioning unit 2, the receiving unit 4, the storage unit 5, and a display unit. And an I / O circuit unit 10 for inputting / outputting data to / from 6 and the like.
[0015]
The positioning unit 2 performs positioning by GPS (Global Positioning System), and a signal of 1575.42 MHz (normally four or more) GPS satellites with an altitude of about 20,000 km (four or more) Radio wave) is received by a receiving antenna (not shown), positioning calculation is performed based on this signal, and positioning data indicating the current position is transferred to the arithmetic processing unit 1.
[0016]
Various operations of the navigation device are performed by, for example, a remote controller 3 as shown in FIG. For example, the remote controller 3 changes the display range of the electronic map on the display unit 6 on the menu button 31 for displaying the operation menu on the display unit 6, and various operation menus displayed on the display unit 6. To move the cursor, to the joystick 32 that can be tilted in at least four directions (any direction here), to the wide area / detail button 33 for changing the display scale of the electronic map on the display unit 6, and to the display unit 6 At least a view button 34 for changing the display method of the electronic map, a determination button 35 for performing a determination operation in the selected state (operating by pressing the joystick 32), and the like. Then, a signal based on the operation information by the remote controller 3 is wirelessly transmitted from the transmission unit 36, received by the reception unit 4, and then transmitted to the arithmetic processing unit 1 to execute the operation content.
[0017]
Further, as shown in FIG. 1, the navigation device includes a storage medium (external storage medium) 11 and a data transmission / reception unit (image data acquisition means) 12 in order to capture image data and the like from at least the outside. . The storage medium 11 and the data transmission / reception unit 12 may be configured to output various data such as image data, registered position information, and travel route information to the outside. Further, the storage medium 11 and the data transmission / reception unit 12 may include both or a configuration including only one of them.
[0018]
Examples of the storage medium 11 include a memory module that can store image data and the like. The storage medium 11 can be detachably attached to the navigation device and has portability. The stored image data and the like can be transferred to the arithmetic processing unit 1 side via the I / O circuit unit 10 with the storage medium 11 attached. Conversely, image data or the like may be transferred from the arithmetic processing unit 1 side to the storage medium 11 side for storage. Here, as such a storage medium 11, it is preferable that the external dimensions are unified and modularized.
By using the removable and portable storage medium 11 as described above, it is possible to easily handle the image data to be captured. Further, by forming the storage medium 11 as a module, it can be shared by other devices other than the navigation device.
[0019]
Examples of the data transmitting / receiving unit 12 include a portable telephone terminal and a portable data communication terminal. For example, it connects to an external network (external image data source) of the Internet through such a data transmission / reception unit 12, downloads image data from a network site, etc., and acquires image data attached to an e-mail. Or take it in. If the data transmission / reception unit 12 is a communication modem or the like, the navigation device can be connected to a communication line, and similarly to the above, it can be connected to an external network such as the Internet to receive image data. The image data received by the data transmitting / receiving unit 12 in this way is transferred to the arithmetic processing unit 1 via the I / O circuit unit 10.
[0020]
The data transmitter / receiver 12 does not necessarily have a function of transmitting and receiving data as described above, and may perform a so-called interface function.
If the data transmission / reception unit 12 has such an interface function, a digital camera or the like (external image data source) is connected to the navigation device, and stored from a storage unit built in (or attached to) the digital camera or the like. The image data and the like can be transferred to the arithmetic processing unit 1 side. Further, the data transmitting / receiving unit 12 having such an interface function may be used for connection with, for example, a personal computer (external image data source). Image data or the like is transferred from the personal computer side to the arithmetic processing unit 1 side. You may make it forward.
[0021]
In this way, the data transmission / reception unit 12 can receive and capture image data from the outside. Furthermore, contrary to the above, image data or the like may be transmitted from the arithmetic processing unit 1 side to the outside via the data transmitting / receiving unit 12.
[0022]
In the navigation apparatus configured as described above, a symbol mark creation program (mark data generation means, symbol mark generation means; hereinafter referred to as “symbol mark creation editor”) is stored in the ROM 8. ing. FIG. 3 is a flowchart showing a flow of symbol mark creation in the symbol mark creation editor.
In order to create a symbol mark with this symbol mark creation editor, first, the operation menu is displayed on the display unit 6 with the menu button 31 of the remote controller 3, and the symbol mark creation mode is selected with the joystick 32 etc. This is determined by the determination button 35. Then, the symbol mark creation editor is activated (step S1 in FIG. 3).
[0023]
Next, image data of an external still image (image, captured image) V is captured from the storage medium 11 or the data transmitting / receiving unit 12 and temporarily stored in the RAM 9 (step S2 in FIG. 3). Here, the image data to be captured is preferably image data that symbolizes an object (location) represented by the symbol mark to be created, for example, a facility, a store, an acquaintance's house, and the like. More specifically, it includes the appearance of facilities and stores, photographs of signs, photographs (images) of acquaintances' faces, and the like. Further, for example, a logo mark unique to a facility or a store can be taken in from a website or the like.
Here, for example, the still image V may be rotated by operating the view button 34 of the remote controller 3. For example, each time the view button 34 is pressed, the still image V is rotated, for example, 90 degrees. This is because, for example, when the still image V is taken with a digital camera or the like, there are a portrait image, a landscape image, an inverted image, and the like.
[0024]
FIG. 4 is a diagram showing an example of a display screen when generating symbol marks. As shown in this figure, the still image V based on the captured image data is displayed on the display unit 6 (step S3 in FIG. 3). Here, the still image V is, for example, a photograph of a user's acquaintance.
Then, along with the display of the still image V, a cutting area frame (editing frame) C having a substantially rectangular shape is displayed on the still image V of the display unit 6 (step S4 in FIG. 3). The cutting area frame C indicates an outer frame of a range cut out from the still image V displayed on the display unit 6.
[0025]
When the cutting area frame C is displayed on the display unit 6, an image A in a range located inside the cutting area frame C is displayed (drawn) as a preview image P at a predetermined position of the display unit 6, for example, at the lower left. Step S5) in FIG. The preview image P is displayed on the display unit 6 in a predetermined size set in advance regardless of the size of the cutting area frame C (the size of the original image A). For this reason, it is necessary to convert the size of the original image A selected in the cutting area frame C to a predetermined size of the preview image P. At this time, mainly by changing the image resolution. good.
[0026]
Here, the cutting area frame C can be resized and moved. As shown in FIG. 5A, in order to enlarge or reduce the cutting area frame C, for example, the wide area / detail button 33 of the remote controller 3 is operated. When this operation is performed, the still image V is left as it is, and only the cutting area frame C is enlarged (operation using a wide area button) or reduced (operation using a detailed button) to a predetermined size. (The aspect ratio remains constant: steps S6 to S7 in FIG. 3).
[0027]
Further, as shown in FIG. 5B, in order to move the cutting area frame C, for example, the joystick 32 of the remote controller 3 is operated. When this operation is performed, the still image V is left as it is, and only the cutting area frame C is moved in the tilted direction of the joystick 32 while maintaining its size and displayed on the display unit 6 (FIG. 3). Middle steps S8-S9).
[0028]
Even when such an operation such as enlargement / reduction or movement of the cutting area frame C is performed, the image A in the range located inside the cutting area frame C after the enlargement / reduction or movement is displayed on the display unit 6. A preview image P is displayed (drawn) at a predetermined position, for example, the lower left (step S5 in FIG. 3). These preview images P are also displayed on the display unit 6 in a predetermined size by changing the image resolution or the like.
[0029]
Then, when the cutting area frame C is enlarged / reduced or moved as necessary, the cutting area frame C can be positioned at a desired size / position (step S10 in FIG. 3), a decision button 35 is operated. Then, image data corresponding to the image A in the cutting area frame C at this time is extracted, and processing such as changing the image resolution is performed to form a symbol mark of a predetermined size. In this way, the image cut out is the same as the image finally displayed as the preview image P.
Thereafter, the image data of the clipped image is stored in the storage unit 5 as image data (mark data, symbol mark data) of the symbol mark M (step S11 in FIG. 3).
[0030]
As described above, a part of an image taken from outside can be cut out and set as the symbol mark M.
[0031]
Here, the symbol mark M is not limited to the rectangular shape as described above, but has various shapes such as a heart shape, a round shape, a triangle shape, a rhombus shape, and a polygon shape as shown in FIG. Is possible. In order to generate the heart-shaped symbol mark M ′, a heart-shaped cutting area frame (editing frame) C ′ as shown in FIG. 6A is prepared in advance, and the inside of the cutting area frame C ′ is prepared. What is necessary is just to cut out only the image A ′ in the range and make it a symbol mark M ′. At this time, the preview image P ′ also has a shape corresponding to the cutting area frame C ′.
When such a symbol mark M ′ is displayed on the display unit 6, the actual image data as a whole is usually set in a range of image data having a substantially rectangular shape as shown in FIG. is there. For this reason, when the symbol mark M ′ has an irregular shape as described above, the image data is in a rectangular range, and pixels in a range outside the cutting area frame C ′ (shaded portion in the figure). The (PIXEL) value is set to a transparent color and the background image (electronic map E) is displayed.
[0032]
The symbol mark M created as described above can be displayed at an arbitrary position on the electronic map according to user settings, as in the case of a normal symbol mark. For this, the position coordinate data for displaying the symbol mark M and the address where the symbol mark M is stored in the storage unit 5 are stored in the storage unit 5 in association with each other. Furthermore, it is possible to associate the name defined by the user with the symbol mark M and store it in the storage unit 5.
[0033]
FIG. 7 is a diagram showing a configuration for displaying the generated symbol mark M by combining it with a map, positioning data, or the like. FIG. 8 shows an example in which the original symbol mark M generated as described above is registered at an arbitrary position on the electronic map E and displayed on the display unit 6 together with the electronic map E.
In such a navigation apparatus, basically, a map display circuit (map data output means) 21 provided in the arithmetic processing unit 1 is used to store a storage medium such as a CD-ROM or DVD-ROM (not shown) as in the conventional case. The map data (other data) composed of the stored electronic information is read, and the map data of the electronic map E in the range selected by the joystick 32, the wide area / detail button 33, etc. of the remote controller 3 is output.
Further, positioning data display circuit (positioning data output means) 22 provided in the arithmetic processing unit 1 outputs its own current position and positioning data based on the positioning result in the positioning unit 2. . Further, the travel route data and the like set by the user are stored in the storage unit 5, and the travel route data and the like set are output by the travel route data output circuit 24 of the arithmetic processing unit 1 as necessary.
When the symbol mark M including the position coordinates is within the range displayed on the display unit 6 of the electronic map E, the image data of the corresponding symbol mark M is calculated by referring to the storage unit 5. The data is output by a symbol mark display circuit (symbol mark display means, symbol mark output means) 25 provided in the processing unit 1.
The output map data, positioning data, travel route data, and image data of the symbol mark M are synthesized in a synthesis circuit (synthetic data output means) 23 provided in the arithmetic processing unit 1 and are displayed on the display unit 6 as synthesized data. Is output. As shown in FIG. 8, on the display unit 6, the symbol mark M, positioning data, moving route data, and the like are combined and displayed on the image based on the combined data, that is, the electronic map E.
At this time, if there is a name defined by the user in the symbol mark M, the name may be synthesized and displayed on the display unit 6. Then, route guidance based on the set travel route is performed by the route guidance program stored in the ROM 8.
[0034]
For example, on the route setting screen for navigation, a symbol mark M registered by the user and a name corresponding to the symbol mark M may be displayed as a list. In this case, the user can also set the starting point, the destination, the waypoint, etc. by selecting the symbol mark M displayed in a list.
Here, the display method of the electronic map E and the symbol mark M as described above is the same as that of a normal symbol mark in the past, and more specifically, for example, a special application already filed by the present applicant. The technique etc. of Kaihei 5-307358 is applicable.
[0035]
In the navigation apparatus described above, a symbol mark M can be generated by cutting out a part of an image captured from the outside. At this time, by using, for example, a photograph of an acquaintance, a photograph of the appearance of a store or a facility, a signboard, etc. as an image captured from outside, each of the generated symbol marks M and a target location (acquaintance) , Stores, facilities, etc.) can be easily linked uniquely. By displaying such a symbol mark M on the electronic map E, the symbol mark M can be easily and reliably identified, improving the screen recognizability of the navigation device, improving the usability, and increasing the added value of the product. it can.
[0036]
In the above embodiment, the operation of the symbol mark creation editor is performed by the remote controller 3, but this is only an example, and the operation may be performed by other methods.
[0037]
Further, in order to generate the symbol mark M of various shapes, for example, a cutting area frame C ′ such as a heart shape is prepared in advance. However, the present invention is not limited to this. For example, a standard rectangular cutting area is used. The frame C may be configured to be deformable into an arbitrary shape. In such a case, for example, performing the deformation operation of the cutting area frame C with the joystick 32 or the like can be realized by applying a method similar to, for example, drawing software of a personal computer. Even when the cutting area frame C has an arbitrary shape as described above, the pixel (PIXEL) value in the outer range may be set to a transparent color and the background image (electronic map E) may be transmitted and displayed. .
Further, the number (type) of symbol marks M that can be generated and registered can be set as long as it is within the range set in advance by the symbol mark creation editor or the storage capacity of the storage unit 5. .
[0038]
Also, there is no intention to limit the configuration of the entire navigation apparatus, and any configuration may be used.
Furthermore, if the electronic map information is displayed, the present invention can be applied to a device other than the navigation device.
[0039]
Further, the present invention may be in the form of a storage medium such as a CD-ROM, a DVD, a memory, or a hard disk that stores a program for performing processing as described in the above embodiment. In particular, if the navigation device has a function that can be connected to an external network such as the Internet via a mobile phone or the like, if the program is executed by a storage medium that stores the program as described above, The configuration as shown in the form can be realized.
In addition, storage means such as a CD-ROM, DVD, memory, and hard disk for storing the program as described above, and the program is read from the storage means and directly or indirectly to the device executing the program. It may be in the form of a transmission device or the like provided with a transmission means for transmitting.
[0040]
In addition to this, there is no problem even if the configuration of each part of the above embodiment is appropriately changed as long as it does not depart from the gist of the present invention.
[0041]
【The invention's effect】
As described above, according to the present invention, image data of an image that symbolizes a target location, such as an exterior or signboard of a facility or a store, a photograph of an acquaintance's face, is taken in from the outside, and a part of the image data is cut out By generating the mark, it is possible to create a user-specific symbol mark, improve the recognizability of the electronic map, improve its usability, and increase the added value of the product.
