Description

The present invention relates to an on-vehicle electronic device such as a radar detector, a navigation device, etc., which has a display means such as a liquid crystal display device and which provides predetermined information to the driver of the vehicle.

2. Description of the Related Art Conventionally, there are on-vehicle electronic devices equipped with a liquid crystal display device that displays various types of information and a voice synthesizer that outputs various types of information as voice. For example, a radar detector, which is an in-vehicle electronic device, detects microwaves emitted from a speed measuring device, stores the installation position information of the speed measuring device in advance, and uses GPS (Global Positioning System) etc. When the acquired current position approaches the memorized installation position (when a predetermined proximity relationship is established), the content of the warning indicating the approach to the speed measuring device is displayed on the liquid crystal display device by pictures, photographs, characters, etc. In addition to displaying the warning, a speech synthesizer is configured to output the content of the warning by voice (Patent Document 1).

A main function of a navigation device is to provide route guidance to a destination based on the positional information of the own vehicle acquired by GPS or the like. A navigation device incorporates map data containing detailed road information, displays a detailed map in color on a liquid crystal display device, and provides route guidance by voice. As such a navigation device, there is a portable one called a PND (Personal Navigation Device) (Patent Document 2). A general PND is detachable from a stand on the dashboard, and the PND can be removed from the stand and carried. In addition, PND has a navigation system exclusively for motorcycles, which is equipped with a housing with a waterproof and earthquake-resistant structure and a reflective liquid crystal that is easy to see even under direct sunlight.

In addition to this, recent automotive electronic devices include radar detectors with navigation functions and navigation devices with alarm functions. In addition to characters, symbols, numbers, etc. indicating such as, an icon indicating the position information (Point Of Interest=POI) of the alarm object is displayed.

JP-A-2009-9546 JP 2010-86215 A Japanese Patent Application Laid-Open No. 2008-292702

However, conventional in-vehicle electronic devices display a wide variety of information such as characters, symbols, numbers, and icons that indicate the names of roads and surrounding facilities on a detailed map that is displayed in multiple colors. Since the information is displayed, the display of the information is inconspicuous, and there is a problem that it is difficult for the user to grasp the necessary information on the map at a glance.

In order to solve such a problem, Japanese Patent Application Laid-Open No. 2008-292702 (Patent Document 3) prepares a normal map displayed in color and a map for highlighting displayed in grayscale, and a map for highlighting is prepared. A map generation device has been proposed in which parking lot marks are displayed in color on the top to make them conspicuous.

However, in recent years, in addition to conventional facility icons such as schools, kindergartens, nursery schools, post offices, fire stations, police stations, factories, shrines, temples, parking lots, etc., navigation devices have added gas stations, restaurants, hamburger shops, convenience stores, etc. Icons such as stores and banks are displayed in different colors for each company. For this reason, many colorful facility icons and company icons are displayed on maps in urban areas and along national highways. There is a problem that the displayed parking lot mark cannot be made conspicuous. Since the above-mentioned company icon is a reproduction of the company's logo design, it cannot be changed to a grayscale different from the color of the logo determined by each company.

Furthermore, in an in-vehicle electronic device equipped with an alarm function, when the vehicle approaches an object to be alarmed, a POI icon must be displayed to attract the user's attention. In a state in which many icons are displayed, it is difficult to recognize at a glance which one is the POI icon, and there is a problem that prompt and reliable alerting cannot be performed in an emergency.

In particular, in navigation devices or radar detectors for motorcycles, the user cannot look away from the front while driving, so the user can see the display on the screen only for a moment, and can find necessary information at a glance. There is an extremely strong demand for understanding. Nevertheless, when a conventional on-vehicle electronic device is mounted on a motorcycle, the design of which is not much different from that of an automobile, the user can easily grasp only the information that the user needs from the display on the screen while driving. I had a problem that I couldn't.

In other words, on-vehicle electronic devices for motorcycles are mounted around the steering wheel of the motorcycle or on the fuel tank. The handlebars and fuel tank area of a typical motorcycle are made up of many metal parts, and automotive electronic equipment that covers the liquid crystal display with a plastic housing matches these metal parts in both appearance and texture. I didn't. Therefore, even if the user tries to see the display on the screen in an instant, the user's eyes are drawn to the plastic housing and the liquid crystal display, which are different from metal parts, and pinpoint the necessary information from the display on the screen. It was difficult to access at points. As a result, in reality, the user who is driving reviews the display on the screen several times to finally grasp the necessary information. In particular, maps, characters, symbols, numbers, icons, etc. displayed on conventional screens have an appearance and texture that is far from the actual metal parts. There is a problem that it attracts the user's attention more conspicuously than metal parts.

The present invention has been made in view of the above problems, and it is possible to easily grasp the necessary information from the display on the screen. To provide an in-vehicle electronic device capable of conspicuously.

In order to achieve the above object, the present invention provides an in-vehicle electronic device comprising: (1) display means capable of displaying a large number of colors on a screen; and control means for controlling display of predetermined information on the screen. The control means displays at least a portion of the information in color, and displays other portions in a monotone color different from the color display. (2) Preferably, the control means displays at least part of the information included in the monotone display in color.

According to the above configuration, for example, among the information displayed on the screen, only the information that the user wants to pay attention to is displayed in color, and the rest is displayed in monotone, thereby making the information required by the user stand out. become able to.

Here, the "display means" in the present invention includes a display capable of displaying information such as an LCD (Liquid Crystal Display), an organic ELD (Organic Electroluminescent Display) or a CRT (Cathode Ray Tube). Display devices are broadly included. Further, "screen" refers to the displayable area of the display of the display means. Furthermore, the display must be capable of displaying "multiple colors" on the screen. For example, if it is possible to display about 60,000 to 260,000 colors, it is possible to form a colorful display, and to express the brightness gradation (change in color density) of a monotone display. . However, there is no limit to the number of colors that can be displayed on the display, and it is desirable to use a display that can display more colors.

Further, the term "color display" in the present invention refers to display expressed using at least one chromatic color different from monotone display. On the other hand, "monotone display" refers to a display expressed with a single color shade or light and shade, and not only a gray scale that expresses only the light and shade differences of achromatic colors such as white, gray, and black, but also a single chromatic color display. It also includes display that expresses only the difference in brightness.

Furthermore, in the above (2), ``a configuration in which at least part of the information included in the monotone display is displayed in color'', when the area of the monotone display is larger than the area of the color display, the color display is reversed. This includes both cases where the display area is larger than the monotone display area, but in both cases, a configuration in which the periphery of the color display is monotone display is preferable. This is because such a configuration makes the boundary between color display and monotone display clear and improves the visibility of color display. More preferably, the monotone display area is larger than the color display area, and the entire color display is surrounded by the monotone display. With such a configuration, the color display as a whole can be clearly conspicuous during the monotone display, and the visibility of the color display is further improved. For example, if a button, which is an operation part, is displayed in grayscale and a portion of the button is displayed in color when the button is operated, instead of displaying the entire button in color, A part (for example, characters, figures, symbols, etc. displayed on the button) may be displayed in color.

(3) Preferably, the control means displays all the information on the screen in a first display mode in which all the information on the screen is displayed in the color display, and displays at least part of the information in color and the other part in the monotone display mode. It is preferable that the second display mode to be displayed can be switched.

According to the above configuration, for example, normally, all information on the screen is displayed in color as before, and when a specific event occurs or based on an instruction from the user, information other than necessary information is switched to monotone display. Therefore, only necessary information can be conspicuously displayed in color.

For example, if this in-vehicle electronic device is a radar detector, normally all information including the map is displayed in color. Appears colored POI icons on the map. In addition, if the in-vehicle electronic device is a navigation device, when the vehicle approaches a left or right turn point, the entire map is switched to a monotone display except for the area around the left or right turn point, and the left or right turn point is displayed. Only the peripheral portion of the right turn point is displayed in color. In these examples, the own vehicle icon on the map should always be displayed in color to make it stand out.

(4) Preferably, when switching from the first display mode to the second display mode, the control means omits a predetermined part of the information and displays the information in the monotone. should be

In recent years, detailed maps installed in radar detectors and navigation devices display text characters indicating the names of major facilities, roads, railways, etc., as well as schools, kindergartens, nursery schools, post offices, fire stations, and police. Facility icons representing stations, factories, shrines, temples, parking lots, etc., and company icons such as gas stations, restaurants, hamburger shops, convenience stores, banks, etc. are displayed. However, users use radar detectors and navigation devices for specific purposes, and it cannot be said that all of the wide variety of information displayed on detailed maps is information that is necessary for the purpose of the user. Conversely, the display of unnecessary information for the user is a factor that hinders the visual recognition of necessary information.

Therefore, according to the above configuration, when switching from color display to monotone display, unnecessary information for the user can be omitted, and the visibility of necessary information can be greatly improved. The "omission of information" as used herein includes not displaying part or all of the information to be omitted. In particular, by not displaying all of the information to be omitted, the visibility of the necessary information that is not to be omitted is improved.

For example, if the on-vehicle electronic device is a radar detector, when the vehicle approaches an object to be warned, when the map is switched to a monotone display, text characters, facility icons, company icons, etc. After simplifying the information displayed on the map by omitting the icons from the screen, POI icons displayed in color appear on the map. After that, when the vehicle passes through the warning target and the warning is canceled, the map is restored to its original state.

In addition, if this in-vehicle electronic device is a navigation device, when the route to the destination is determined, when switching the map to monotone display, text characters, facility icons, company icons unrelated to the route of the vehicle may be displayed. is omitted from the screen. In this case, it is preferable that the road along which the vehicle travels, text characters indicating information about the road, facility icons, and company icons are displayed in color. After that, when the vehicle reaches the destination and the navigation device finishes the guidance, the map is restored to its original state.

Note that the process of switching from color display to monotone display and the process of omitting unnecessary information on color display may be performed at the same time, or may be performed one after the other. Preferably, the timing should be such that the user can recognize that unnecessary information has been deleted at the same time as switching to the monotone display.

(5) Preferably, the control means displays a plurality of the information as objects on the screen, and when displaying the information, displays one or more of the objects in the color and displays the other information in the monotone. It is preferable to have a configuration that

According to the above configuration, among various objects displayed on the screen, only objects showing information necessary for the user can be displayed in color to make them stand out. The "object" here includes, for example, all virtual objects such as a map displayed on the screen, text characters, icons, an operation unit to be described later, and a window frame that divides the display area. Among them, only objects showing information necessary for the user are displayed in color, and objects showing other information are displayed in monotone.

(6) Preferably, the control means displays a plurality of predetermined objects for the same type of information or a plurality of predetermined objects for different types of related information in the color display.

According to the above configuration, when there is a plurality of pieces of information required by the user or information related to the information required by the user, it is possible to highlight all the objects representing these pieces of information by displaying them in color. For example, if the vehicle-mounted electronic device is a radar detector, when the vehicle approaches a plurality of warning targets, the POI icons of the same type or different types are displayed in color on a monotone map. In addition, if this vehicle electronic device is a navigation device, only a specific type of facility icon (ex. post office) among the facility icons along the road along which the vehicle is traveling is displayed in color on a monotone map. indicate. Furthermore, since the company icon that reproduces the logo design cannot be displayed in monotone, in such a case, the company icon necessary for the user (ex. convenience store) is displayed in color, and the unnecessary company icon is displayed. should be omitted.

As described above, according to the present in-vehicle electronic device, only the information necessary for the user can be displayed in color to make it stand out. , the user can easily visually recognize necessary information. As a result, in the future, even when detailed information is loaded on the maps of radar detectors and navigation devices, it will be possible to visually pick up only the necessary information by either color display, monotone display, or omission of display. It is possible to further improve the performance of electronic devices for vehicles.

Here, "the same type of information" and "related different types of information" in the present invention will be briefly described. First, whether a plurality of pieces of information are of the "same type" or "different types" can be determined according to social conventions. The same applies to whether or not a plurality of pieces of information have "relevance". According to the above example, only the post office icon among the facility icons may be defined as "the same type", and the facility icons include school, kindergarten, nursery school, post office, fire station, police station, factory, Shrines, temples, parking lots, etc. may be defined as "the same type" or "related different types." Then, the data may be associated with each other by adding a common identifier to each data for displaying these icons.

(7) Preferably, the color display is a 3D object, the monotone display is a 2D object, and the color display, which is a 3D object, is arranged on the monotone display, which is a 2D object.

According to the above configuration, in addition to the difference between color display and monotone display, a difference between 3D and 2D can be provided between an object indicating necessary information for the user and an object indicating unnecessary information, It is possible to more easily grasp the necessary information from the information displayed on the screen.

For example, facility icons, company icons, POI icons, and the like required according to the purpose of the user may be displayed as 3D objects in color and arranged on a map as 2D objects in monotone display. In this case, the icons necessary for the user can be viewed three-dimensionally on a flat map and can be visually recognized quickly because the colors can attract the user's attention.

Further, means for distinguishing necessary information are not limited to the difference between color display and monotone display, and the difference between 3D and 2D. For example, the color display 3D object described above can be moved on a monotone display 2D object, which is a still image, to give a difference between "moving" and "still". It is also possible to float on a 2D object to create a height difference. By providing these differences, weight can be given to a large amount of information displayed on the screen, and only necessary information can be directly conveyed to the user.

(8) Preferably, the control means divides the screen into a plurality of display areas, displays different information in each of the display areas, and displays the information in at least one of the display areas in the monotone display. should be

According to the above configuration, even when the screen is divided into a plurality of display areas and different information is displayed in each display area, necessary information for the user can be highlighted. In this case, color display and monotone display may be distinguished in one display area, or color display and monotone display may be distinguished in each of a plurality of display areas. As an example of the former case, a first display area that displays a large detailed map on the entire screen and a second display area that displays an enlarged map when the vehicle approaches an alarm target or a left or right turn point are provided. First, one of the maps displayed in the first or second display area is displayed in monotone. In addition, as an example of the latter, both maps displayed in the first or second display area are displayed in monotone, and the vehicle icon, the road along which the vehicle travels, the POI icon, and the left or right turn points on each map are displayed. The facility icons and company icons that serve as landmarks are displayed in color.

(9) Preferably, the control means displays on the screen an operation unit capable of receiving an input from a user, and when displaying the operation unit, at least part of the operation unit is displayed in color, and other portions are displayed in color. may be configured to display monotone in a color different from the color display. For example, (10) the control means displays the operation unit in the monotone display before receiving input from the user, and displays at least a part of the operation unit in the color after receiving the input from the user. or (11) the control means can display on the screen an operation unit capable of receiving an input from a user, and in the display, before receiving an input from the user Preferably, the operation unit is displayed in color, and at least a part of the operation unit is displayed in monotone after receiving an input from the user.

So far, the map displayed on the screen, and the characters, symbols, figures, facility icons, company icons, etc. on the map have been exemplified as application objects of the present invention. It can also be applied to the operation part displayed above. Here, the "operation unit" is a display on the screen for receiving input from the user to cause the in-vehicle electronic device to execute various functions or to set various functions. 2D or 3D objects such as icons and buttons (including those with different expressions such as switches, keys, bars, etc. that are the same input means as these operation units) that express contents and program functions with characters, figures, symbols, etc. widely included.

According to the above configuration, almost the entire operation section is displayed in monotone, and information such as characters, figures, and symbols included in the operation section, which the user wants to pay attention to, can be highlighted by color display, and displayed on the operation section. It is possible to easily grasp the information such as the function that has been implemented. As a result, it is possible to improve the operability of the in-vehicle electronic device, and it is possible for the user to operate it quickly and accurately.

In addition, the operating unit to which the present invention is applied color-displays the part to be noticed before the user's input, and switches the color display to monotone display after the user's input (that is, after the input, the entire operation unit is displayed in monotone. become). Conversely, the entire operation unit may be displayed in monotone before the user's input, and the part to be noticed may be displayed in color after the input. In addition, regardless of whether the input is performed by the user or not, the portion of the operation unit that the user wants to draw attention to may always be displayed in color.

(12) Preferably, the operation unit is a 2D or 3D object imitating an icon or button for causing the control means to execute one of a plurality of pre-programmed functions, or (13 ) The operating unit may be a 2D or 3D object modeled after a keyboard including a plurality of keys for entering letters, numbers or symbols.

According to the above configuration, almost the entire operating section such as icons, buttons, and keys are displayed in monotone, and information such as pictograms, text characters, numerals, symbols, graphics, and other functions included in these operating sections are displayed to the user's attention. It is possible to make the desired part stand out by color display, facilitate the user's understanding of the meaning and content, and facilitate the selection of the operation unit, thereby realizing quick and accurate operation.

The present invention having the above configuration includes, for example, i) a plurality of menu buttons displayed on the menu screen of the in-vehicle electronic device, ii) volume adjustment button, brightness adjustment button, and various setting buttons displayed on the option screen, and iii ) Buttons such as "Yes", "No", "OK" displayed on the confirmation window, iv) Map scale switching button displayed on the map screen, screen display switching button, menu bar, v) Displayed on the input screen It can be widely applied to operation units such as various keys of a keyboard, and it is possible to make information contained in the operation unit and other parts that the user wants to pay attention to be conspicuous by color display.

(14) Preferably, the control means can display a map on the screen, and display at least the elements included in the land area of the map in the monotone display. For example, (15) the land elements of the map include at least a ground color indicating land, a high-standard road, and a low-standard road, and based on the brightness of the ground color, the brightness of the high-standard road is high, and the lightness of the high-standard road is low. It is preferable to adopt a configuration in which the brightness of the standard road is set low. (16) More preferably, the control means is capable of switching the map to the color display or the monotone display, and when switching from the color display to the monotone display, the color display of the map includes: It is preferable that a part of the information is omitted and the map is displayed in the monotone.

The above configuration is a specific example in which the present invention is applied to a map of a radar detector or a navigation device. You can make it stand out on the map. Here, the "elements included in the land area of the map" include ground colors, high-standard roads, and low-standard roads that indicate land, as well as traffic lights, traffic signs, national road signs, facility icons, landmarks, and POI icons. Widely includes various elements displayed on the land surface of the map such as. According to the present invention, among these elements, those which are desired to attract the user's attention are displayed in color to make them stand out. However, even if the company icon is an element included in the land area of the map, it cannot be displayed in monotone. Therefore, unnecessary company icons are omitted when the map is switched from color display to monotone display. In addition, if the map is simplified by omitting unnecessary information from the monotone display of the land elements included in the land area of the map, the color display on the map can be made more conspicuous.

Here, the "necessary information" and "unnecessary information" on the map may be determined based on the functions of the in-vehicle electronic device. Based on whether or not the information is necessary, it may be determined whether or not to omit the information when switching to the monotone display. The "necessary information" identified by such criteria should be displayed conspicuously in color or in monotone and left on the map, depending on the need to fulfill the function. On the other hand, "unnecessary information" specified by the above criteria is omitted when switching to monotone display. As a result, it is possible to display only "necessary information" according to the purpose of the user on the screen, and to display in color the information that is particularly necessary in order to achieve the function.

For example, a radar detector has an alarm function that displays a POI icon indicating the location information of a speed measuring device to alert the user. In order to perform this warning function, one or more POI icons indicating a map, a road, an own vehicle icon, and a detected speed measuring device are required, and these correspond to "necessary information". In addition, the "necessary information" may include facility icons, company icons, and the like that serve as landmarks on the road along which the vehicle travels. When the user turns on the warning function and the vehicle approaches the speed measuring device, for example, the vehicle icon and POI icon are displayed in color, and maps, roads, facility icons and company icons that serve as landmarks are displayed. The map is displayed in monotone, and "unnecessary information" other than these, such as text characters, unnecessary facility icons and company icons outside the course, are all omitted from the map.

Here, the more “unnecessary information” is omitted from the map, the more “necessary information” can be visually recognized. Only the top POI icon, preferably the nearest POI icon, may be displayed in color, and other POI icons may be omitted from the monotone map. Even if a lot of information is omitted from the map, the omitted "unnecessary information" will be displayed again on the map after the warning is lifted, so there is no effect on the normal display of the radar detector. As described above, according to the present invention, when a user requests execution of a predetermined function provided in an in-vehicle electronic device, only the information necessary for executing the function is displayed on the screen, and among the necessary information, the necessary information is displayed on the screen. Only important information can be displayed in color to make it stand out. As a result, when the function is executed, the user can grasp necessary information on the screen at a glance.

Similar to the above, for example, the navigation device has a route guidance function that guides the vehicle to the destination. In order to perform this route guidance function, it is necessary to have a map, a road indicating the route to the destination, a vehicle icon, and a facility icon or company icon that serves as a landmark near the left or right turn point. ”. Then, when the user sets the destination and starts route guidance, only the road indicating the route to the destination, the own vehicle icon, and the facility icon or company icon that serves as a landmark near the left or right turn point are colored. Along with the display, the entire map including the surrounding roads becomes a monotone display. At this time, text characters, facility icons, company icons, etc. that are not related to the route guidance are all omitted from the map. As a result, when the route guidance function is executed, the user can grasp the route to the destination displayed on the screen at a glance.

(17) Preferably, the control means can execute an alarm function of displaying an alarm icon indicating the position of a predetermined alarm target on the map when a predetermined condition is satisfied, and the alarm The map may be displayed in color when the function is not executed, and the map may be displayed in monotone when the alarm function is executed.

According to the above configuration, when the in-vehicle electronic device has an alarm function, when the own vehicle approaches an object to be alarmed, the alarm icon is displayed in color on the monotone display map, and the user's eyes are alerted. It can be attracted to alarm icons on the map. As a result, the user who sees the warning icon can easily grasp the type and position of the warning object and the distance to which the own vehicle will reach, and prompt and reliable alerting is performed in an emergency.

The "alert icon" here includes the POI icon described above, and also broadly includes an icon indicating position information of a predetermined target object (or target area) that needs to be notified to the user. The object of notification can be arbitrarily set, and an alarm icon is displayed on the screen when the conditions for starting notification are satisfied.

Also, the alarm icons are preferably grouped according to the type and degree of importance of the target object, and the type and degree of importance are expressed in a common color and shape. For example, according to the degree of urgency of the object, it is grouped into warning, warning, and notification, and the icon of the object requiring a warning is ``red'', and the icon of the object requiring a warning is ``yellow''. The icon of the object that can be used alone is distinguished by the color "blue" or "green".

More specifically, objects requiring alerts can include, for example, loop coils, LH systems, H systems, speed measuring devices such as radar orbis. In addition, objects that require warning include, for example, mousetrap areas, mobile orbis areas, tracking enforcement areas, temporary stop enforcement areas, intersection enforcement areas, other enforcement areas, seatbelt inspection areas, drinking inspection areas, and mobile phones. It can include checkpoint areas, other checkpoint areas, intersection monitoring points, red light suppression systems, etc. Furthermore, objects that need to be notified include, for example, highway traffic police, N system, traffic monitoring system, police station, accident-prone area, service area, parking area, highway oasis, highway length/continuous tunnel, highway radio Reception areas, roadside stations, viewpoint parking, parking lots, public restrooms, etc. can be included.

(18) Preferably, light reflection and shadows are drawn by the contrast of the color of the monotone display, and the monotone display is a 2D or 3D object having an appearance imitating a metal surface.

According to the above configuration, the information displayed on the screen can be distinguished not only by the difference between color and monotone, but also by the presence or absence of visually recognizable texture of the metal surface. become.

In other words, the color display in the monotone display catches the user's eye due to the difference in color, but both have the commonality of being abstract displays (in extreme terms, both are "pictures"). There was a certain limitation when distinguishing visually. Therefore, in the present invention, which has the above configuration, the mere monotone display is taken one step further, and an object having a metal surface drawn with the difference in brightness is used, and a "texture" that can be distinguished at a glance from the abstract color display. It was decided to give a difference of Recent advances in CG technology and higher resolution displays have enabled expressions ranging from abstract paintings (non-photorealistic) to photo-realistic expressions (photorealistic). Even a relatively small display means mounted on the equipment can express a realistic metal surface as if it were the actual object.

(19) Preferably, a hairline pattern is drawn on the metal surface of the 2D or 3D object by the contrast of the color of the monotone display.

According to the above configuration, by adding a hairline pattern to the metal surface of a monotone 2D or 3D object, it is possible to draw the texture of the metal surface more realistically, and the difference in "texture" from color display. becomes even more pronounced. Here, the term "hairline" generally refers to a method of finishing a metal surface, in which fine linear scratches are made on the metal surface by polishing. The "hairline pattern" in the present invention is not particularly limited, but includes, for example, vertical, horizontal, and oblique linear linear flaws, as well as linear flaws such as circles spreading outward from the center.

In addition, in order to draw the metal surface of a 2D or 3D object more realistically, not only the hairline pattern, but also the metal processing such as punch holes, uneven patterns, slits, engravings, screws, etc., cloudiness, rust, Alteration of the metal surface such as cracks and cracks may be expressed. Alternatively, the metal surface of a 2D or 3D object may be mirror-finished without adding a hairline pattern.

(20) Preferably, the display for transmitting the information is drawn on the metal surface of the 2D or 3D object by the contrast of the color of the monotone display.

According to the above configuration, by including predetermined information in monotone display on the metal surface of the 2D or 3D object, the information can be made inconspicuous. Preferably, if the information is drawn by simulating general metal processing, the texture of the metal surface of the 2D or 3D object can be represented more realistically. For example, on the metal surface of a 2D or 3D object, it is possible to draw the information unevenly by simulating etching or engraving, or to draw the information on a plane by simulating the surface treatment of an oxide film. Yes, it can make a 2D or 3D object look more metallic.

(21) Preferably, the color of the monotone display has chroma, and the color is used to represent the coloring of the metal surface of the 2D or 3D object by surface treatment of the metal.

According to the above configuration, the metal surface of a 2D or 3D object can be displayed in monotone with one color having saturation without impairing the texture of the metal. The term "color development by metal surface treatment" as used herein includes, for example, color development treatment by an oxide film on the metal surface, dyeing treatment for clear finish, and the like. By coloring to imitate these surface treatments, the appearance of 2D or 3D objects can be made to look like a colored metal surface without impairing light reflections and shadows, hairline patterns, etc. for expressing the texture of the metal.

(22) Preferably, the monotone-displayed 2D or 3D object is configured to be an object with an appearance that imitates a metal plate.

According to the above configuration, a 2D or 3D object that looks like a metal surface can be given contours and thickness to make it look like an actual metal part, and the difference in "texture" from color display is further improved. become conspicuous. The "appearance imitating a metal plate" here is not limited to a flat metal plate, but also includes a three-dimensionally processed metal plate.

(23) Preferably, the display for transmitting the information is drawn on the metal plate, which is the monotone display, in an expression simulating metal unevenness processing or punching processing.

According to the above configuration, as described above, a 2D or 3D object can be obtained by drawing information on a monotone metal plate by simulating unevenness and punching formed by metal processing such as etching, engraving, and punching. can make the appearance look more metallic.

For example, the map displayed on the screen is a flat metal plate, and information such as roads, traffic lights, traffic signs, national road signs, facility icons, landmarks, etc. It is possible to draw by simulating unevenness and voids formed by. In addition, the operating parts such as icons, buttons, and keys displayed on the screen are made of flat or three-dimensionally processed metal plates, and information such as characters, figures, and symbols are applied to these operating parts by etching, engraving, punching, etc. Concavities and convexities formed by metal processing and punching may be simulated and drawn.

(24) Preferably, the control means switches the display for transmitting the information included in the monotone display to the color display. (25) More preferably, the display for transmitting the information is drawn on the metal plate which is monotone display in an expression simulating metal punching, and the display simulating the punching is displayed on the metal plate. It is preferable to switch to the above-described color display in such an expression that the display is illuminated from the back side of the display.

According to the above configuration, almost the entire map and operation section are displayed in monotone, and among the information included in these, only the information that the user wants to pay attention to is highlighted by color display, and the necessary information is displayed on the screen. can be easily grasped. In particular, by switching the information that mimics the punching process to a color display, it is possible to create a difference in the "physical attributes" of the metal and the light between these displays, with an expression that is illuminated from the back side of the metal plate, which is a monotone display. This makes it possible to make color display more conspicuous during monotone display.

Here, the configurations of the present invention described in the above (18) to (25) are particularly effective for in-vehicle electronic equipment for motorcycles. First, it is possible to make information displayed in color stand out by providing differences in "color", "texture" and "physical attribute" between monotone display imitating a metal surface and color display. The user can easily grasp necessary information even while driving the motorcycle. Secondly, the monotone display simulating a metal surface matches the metal parts around the steering wheel and fuel tank of the motorcycle in appearance and texture, making the monotone display less conspicuous in the user's field of vision. That is, in the present invention, by making the appearance of the monotone display a metal surface, it is made to mimic the actual metal part. As a result, the color display on the screen particularly attracts the user's eye, and the required information can be conveyed instantaneously.

Furthermore, if the electronic device for vehicle that implements the display modes of (18) to (25) above has a housing configured as described in (26) to (30) below, only the display on the screen In addition, the overall electronic device for vehicle can increase the sense of unity with the metal parts of the motorcycle, and improve the visibility of the color display, which is remarkably different in appearance and texture from metal.

It is possible to make the housing inconspicuous in the field of view. As a result, the information displayed in color on the screen is more conspicuous, and the user can access the required information with pinpoint accuracy.

(27) Preferably, the monotone display has an appearance that imitates the metal surface of the housing. Further, (28) more preferably, the in-vehicle electronic device is for a two-wheeled vehicle, and at least the peripheral portion of the screen of the housing has an appearance imitating the surface of any one of metal parts constituting the two-wheeled vehicle. It is preferable to have a configuration in which

In the interior of the vehicle, which is mainly made of synthetic resin materials, even if the housing of the on-vehicle electronic device is made of synthetic resin, it does not particularly attract the user's attention. However, the exterior of a motorcycle is made up of metal parts, and an in-vehicle electronic device covered with a synthetic resin housing does not match the appearance and texture of these metal parts. It attracts me.

Therefore, according to the above configuration, the monotone display on the screen, the housing adjacent to the screen, and the appearance of the metal parts constituting the motorcycle are each a common metal surface, and the information displayed in color on the screen can be clearly displayed. can stand out. The term "two-wheeled vehicle" as used herein includes, for example, bicycles and motorcycles, and the vehicle-mounted electronic device is particularly suitable for motorcycles that are composed of many metal parts. In other words, when this in-vehicle electronic device is mounted on a motorcycle, the on-vehicle electronic device, including the screen and housing, has better visibility of the color display, which is significantly different in appearance and texture from metal. It becomes possible to As a result, even a motorcycle user who cannot look away from the front while driving can see the display on the screen for a moment and grasp necessary information at a glance.

(29) Preferably, of the housing, at least the visible range when the screen is viewed in the vertical direction is made of metal or non-metal with an appearance simulating a metal surface.

According to the above configuration, the exterior of the housing of the in-vehicle electronic device can be made to have a metal surface within the visible range of the user who drives the motorcycle, and the eyes of the user looking at the screen can easily see the housing. can be prevented from being attracted to

A memory card reader 17 such as an SD card shown in FIG. 2 is built right under the waterproof cover 14, and the waterproof cover 14 protects the memory card reader 17 from water droplets and dust. On the other hand, the headphone terminal 19 and the USB terminal 20 shown in FIG. 2 are built in directly under the waterproof cover 15, and the waterproof cover 15 protects the headphone terminal 19 and the USB terminal 20 from water droplets and dust. A waterproof rubber sheet (not shown) is also interposed between the housing 11 and the power switch 16 to prevent water droplets from entering the housing 11 through the joint.

Here, as shown in FIG. 2, a memory card 18 in which map data and the like are recorded is inserted into the memory card reader 17 . The navigation apparatus 10 can use the map data stored in the memory card 18 for route guidance. In addition, the navigation device 10 can be connected to a personal computer via a USB terminal 20 to upgrade software applications. Furthermore, in addition to the route guidance function, the navigation device 10 also has an alarm function for detecting a vehicle speed measuring device or the like. , type information, etc.) can be updated.

When the data stored in the memory card 18 has update information, the control section (control means) 26 stores (downloads) the update information in the database 27 and updates the data in the database 27 . The database 27 can be realized by a non-volatile memory (for example, EEPROM) inside the microcomputer of the control unit 26 or externally attached to the microcomputer.

Returning to FIG. 1(b), a battery cover 21 is fitted to the right side of the rear surface of the housing 11 in the figure, and a battery (not shown) is accommodated directly below the battery cover 21. As shown in FIG. A waterproof rubber sheet (not shown) is also interposed between the housing 11 and the battery cover 21 to prevent water droplets from entering the housing 11 through the joint. As the battery of the navigation device 10, for example, a rechargeable battery such as a lithium ion battery may be used.

Inside the housing 11, a speaker 22, a GPS receiver 23, a microwave receiver 24 and a wireless receiver 25 are built. The speaker 22 outputs sounds such as various operation sounds, effect sounds, voice guidance, reroute sounds, speeding sounds, GPS positioning sounds, and non-positioning sounds, for example. Furthermore, the navigation device 10 has a music player function, and can output music data stored in the memory card 18 from the speaker 22 . When a headphone (not shown) is connected to the headphone terminal 19, the above sound is output from the headphone.

In FIG. 2, the control unit 26 is mainly composed of a CPU (Central Processing Unit) that performs control processing according to a program, and includes the various input devices described above (touch panel 13, GPS receiver 23, microwave receiver 24, wireless reception device 25, etc.), and outputs a predetermined message or alarm using an output device (display unit 12, speaker 22, etc.).

Various functions of the navigation device 10 are stored as programs in the EEPROM of the control section 26, and are realized by the CPU executing the programs. Various functions of the navigation device 10 will be described in detail below.

<<Route guidance function>>
The database 27 stores road network information for route guidance. The control unit 26 can use this road network information to search for a route (route) from one position to another. The database 27 also stores a telephone number database in which telephone numbers are stored in association with location information and names of houses, companies, facilities, etc. of the telephone numbers, and addresses and location information of the addresses are stored in association with each other. and an address database are stored. The control unit 26 reads road network information around the current position from the database 27 and causes the display unit 12 to display a map around the current position.

And the control part 26 can perform a route guidance function. First, the control unit 26 causes the display unit 12 to display a destination setting menu (see FIG. 16). This destination setting menu includes a telephone number search button, an address search button, a facility name search button, etc., which urge the user to select a destination setting method. Select a setting method.

For example, when the phone number search button is pressed, the control unit 26 displays a phone number input screen and acquires the position information corresponding to the inputted phone number from the database 27 . When the address search button is pressed, an address selection input screen is displayed, and position information corresponding to the input address is acquired from the database 27 . The control unit 26 sets the acquired position information as the position information of the destination, and obtains a recommended route from the current position to the destination based on the road network information stored in the database 27 . As a method for calculating this recommended route, for example, a known method such as the Dijkstra method can be used. The control unit 26 displays the calculated recommended route together with a surrounding map. For example, the route from the current position to the destination is displayed in a predetermined color (for example, "green") as the recommended route.

<< Radar scope display function >>
The database 27 stores location information of alarm targets such as speed measuring devices together with their types. The radar scope display function searches for alarm targets within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 23 based on the position information stored in the database 27, and automatically displays the target. This is a function of displaying the relative positional relationship between the vehicle and the alarm object on the display unit 12 .

During the execution of the radar scope display function, the control unit 26 causes the display unit 12 to display a map and an arrow-shaped own vehicle icon indicating the position of the own vehicle on the map. In addition, when an event occurs (when a predetermined condition for issuing an alarm is satisfied) while the radar scope display function is being executed, "L", "RD", "P", "N", etc. are displayed on the map. to indicate the type and position of the alarm object. When an event occurs during execution of the radar scope display function, the control unit 26 performs control processing for executing any one of the following GPS warning function, radar wave warning function, and wireless warning function. .

<<GPS alarm function>>
The control unit 26 displays an alarm on the display unit 12 when the current position detected by the GPS receiver 23 and the position of the alarm object stored in the database 27 approach each other within a predetermined distance. As a display mode of the alarm, for example, a POI icon indicating the position information of the object to be alarmed is displayed on the map (see FIG. 19), or an alarm screen is displayed superimposed on the currently displayed map screen (FIG. 23). ). At this time, the control unit 26 performs a process of outputting from the speaker 22 a voice indicating the type and distance of the warning object, for example, "500m ahead LH system".

Examples of objects to be warned by the GPS warning function include speed measuring devices (loop coil, LH system, H system, radar type orbis, etc.), mouse trap areas, moving orbis areas, tracking control areas, temporary stop control areas, and intersections. Control area, other control area, seat belt inspection area, alcohol inspection area, mobile phone inspection area, other inspection area, intersection monitoring point, signal ignorance suppression system, expressway traffic police, N system, traffic monitoring system, police station, Accident-prone areas, service areas, parking areas, highway oasis, highway long/continuous tunnels, highway radio reception areas, roadside stations, viewpoint parking, parking lots, public toilets, etc.

<<Radar wave warning function>>
The radar wave warning function displays a warning on the display unit 12 and emits a warning sound from the speaker 17 when the microwave receiver 24 detects radio waves corresponding to microwaves in a predetermined frequency band emitted from the speed measuring device. This is an alarm function that outputs For example, when microwaves in a predetermined frequency band emitted by the speed measuring device are detected by the microwave receiver 24, a schematic diagram or photograph of the radar stored in the database 27 is displayed on the display unit 14 as an alarm. , the voice data stored in the database 27 is read out, and the voice "It's radar. Be careful of the speed" is output from the speaker 22.例文帳に追加

<<Wireless alarm function>>
The radio alarm function is a function of issuing an alarm so as not to hinder the movement of the emergency vehicle or the like when the radio receiver 24 receives radio waves emitted by the emergency vehicle or the like. In the radio alarm function, control radio, car location radio, digital radio, special radio, station active radio, police phone, police activity radio, tow radio, helicopter radio, fire helicopter radio, firefighting radio, emergency radio, expressway radio , security radio frequencies, etc., and when a radio signal is received at the scanned frequency, a schematic diagram indicating that the radio signal corresponding to the frequency stored in the database 27 for each radio type has been received is displayed as an alarm screen. While displaying on the display unit 12 , the voice data stored in the database 27 for each wireless type is read out, and an alarm sound indicating the wireless type is output from the speaker 22 . For example, when receiving a crackdown radio, a voice such as "This is crackdown radio. Be careful of speed" is output.

Here, in the radar scope display function, GPS alarm function, radar wave alarm function, and radio alarm function, a plurality of different types of alarm objects are set as described above, and each alarm object has its own type. Priority is set. The priority of each alarm target is visualized, for example, by classifying the color of the alarm icon into groups of "red", "yellow", "blue", or "green" in descending order of priority (Fig. 14 ).

<Case>
Next, the housing 11 of the navigation device 10 will be described in detail. In FIGS. 1(a) and 1(b), the present navigation device 10 uses a housing 11 made almost entirely of metal. As shown in FIG. 3, the navigation device 10 is mounted around a handlebar 31 of a motorcycle 30. In this embodiment, the metal surface of the housing 11 matches the metal parts around the handlebar 31. Appearance and texture.

Also, in this embodiment, the parts denoted by reference numerals 23, 24 and 25 on the rear surface of the housing 11 shown in FIG. And the radio wave to be received by the radio receiver 25 can be transmitted. Note that if the receivers 23 to 25 can receive radio waves, the housing 11 can be made entirely of metal. For example, a slit or a small hole for radio wave reception is provided on the back of the housing 11, or the antennas of the receivers 23 to 25 are arranged outside the housing 11 and connected with a connector or the like. In some cases, the housing 11 can be made entirely of metal.

Metal parts such as a handlebar clamp 32, a top bridge 33, a speedometer 34, a tachometer 35, a front fork 36, and a fuel tank 37 are concentrated around the handlebar 31 of the motorcycle 30. By making the navigation device 10 mimic the metal parts around the steering wheel 31, the navigation device 10 is made visually inconspicuous. This prevents the eyes of the user from being drawn to the housing 11 when the user is driving and tries to see the display of the navigation device 10 .

The metal surface of housing 11 preferably has the same or similar appearance and texture as any of the metal parts around handle 31 . For example, if the cases of the steering wheel 31, the speedometer 34 and the tachometer 35 are plated, the surface of the housing 11 can be plated to give them the same appearance and texture as those metal parts. Further, for example, if the handle clamp 32 and the top bridge 33 are made of unpainted aluminum, the housing 11 is also made of unpainted aluminum so that the same appearance and texture as these metal parts can be given. On the other hand, when the navigation device 10 is mounted on the fuel tank 37 , the housing 11 should be painted in the same color as the fuel tank 37 .

In the present embodiment, the housing 11 is made entirely of metal, but at least the portion visible to the user during driving is made of metal, and the other portions are made of non-metal such as plastic having sufficient strength. It may be made of carbon fiber or the like. Specifically, the housing 11 can be divided into two parts, the front side and the back side, and the front half covering the periphery of the display unit 12 can be made of metal, and the back side half can be made of non-metal. Preferably, the non-metallic back side half is colored black (more preferably, matte black) to reduce light reflection, so that it is less likely to attract the eyes of the user while driving and easily matches the surrounding metal parts.

Moreover, all or part of the housing 11 may be made of non-metallic material, as long as it is made of a material that can be processed to have an appearance that resembles a metallic surface. For example, the housing 11 may be made of general-purpose plastic such as ABS or polypropylene, or general-purpose engineering plastic such as polyacetal or polycarbonate, and these plastics may be plated.

<Display mode of the display unit>
As described above, in the present embodiment, the housing 11 of the navigation device 10 mimics the metal parts around the steering wheel 31 to make it difficult to attract the eyes of the user while driving. The object of the present invention, which is to allow the user to grasp necessary information instantaneously, is not achieved. In order to achieve this purpose, in this embodiment, among the information displayed on the display unit 12, less important information is simulated by the metal parts 32 to 37 around the steering wheel 31 to make it inconspicuous, thereby improving the visibility of the necessary information. markedly increased. Characteristic display modes of the display unit 12 in this embodiment will be described below with reference to FIGS. 4 to 14. FIG.

＜＜Menu screen＞＞
4A and 4B are front views of menu screens displayed on the display unit 12 when the power of the navigation device 10 is turned on. 4A, the menu screen of the present embodiment includes a background 41, a navigation button 42, a music button 43, a picture button 44, and an option button 45 (hereinafter collectively referred to as "displays 14 to 45"). There is). These displays 41 to 45 are all monotone displays expressed in grayscale, and the metal surface is drawn only by the light and shade differences of the achromatic colors of white, gray, and black. The monotone display is a display expressed by a single color shade or brightness, and may be a display expressed by a single chromatic color such as red or blue, in addition to a gray scale.

In the present embodiment, each of the displays 41 to 45 is an object with an external appearance that imitates a metal plate, and displays that imitate the texture of the metal surface and the actual metal processing are realized by the difference in light and dark colors of the monotone display. forming. Preferably, the background 41 is a 2D object, and the navigation button 42, music button 43, picture button 44 and option button 45 are 3D objects. , and the operability of the menu screen can be improved.

<<<Drawing on metal surface>>>
First, as an expression common to these displays 41 to 45, reflection of light and shadows are drawn by the difference in brightness of the monotone display color to imitate the luster of the metal surface. For example, with respect to the background 41 in FIG. 4A, the range indicated by "bright" is light reflection, and the range indicated by "dark" is shadow. Further, in this embodiment, the hairline pattern 40 is drawn on the entire surface of each of the displays 41 to 45 to dull the luster of the metal surface. In this way, the metal surface can be expressed at least by drawing a glossiness, and by adding the drawing of the surface treatment performed in actual metal processing, it is possible to make it look more like a metal surface. becomes.

In addition, in FIGS. 4A and 4B, the hairline pattern 40 is exaggerated and schematically shown for convenience of explanation, but in the actual display, a hairline pattern equivalent to that of the actual metal part is displayed. can be drawn (see Figures 15 and 16). In this way, the metal surface of each of the displays 41-45 can be rendered with at least light reflection and shadows, and can be made to look more like a metal surface by adding metal processing elements such as the hairline pattern 40. . As a result, the appearance and texture of the metal parts 32 to 37 around the steering wheel 31 of the motorcycle 30 shown in FIG. It is possible to make them common and make the background and the buttons themselves inconspicuous.

Here, the metal surfaces of the displays 41 to 45 of the display unit 12 are preferably drawn to have an appearance and texture similar to the metal surfaces of the metal parts 31 to 37 of the housing 11 and the motorcycle 30. It is more preferable that the images are drawn with such high image quality and high definition that they are indistinguishable. However, even a drawing that at least looks like a metal surface when viewed momentarily by a user driving a car exhibits a mimicry effect that makes it difficult for the user's eyes to be attracted.

<<<Information Drawing>>>
Each display 41-45 includes characters 41a-45a and figures 42b-44b for transmitting information such as functions. In this embodiment, these characters 41a to 45a and figures 42b to 44b are displayed by a drawing method different from the conventional one. That is, the characters 41a to 45a and the figures 42b to 44b are all drawn to imitate general metal processing by the difference in color contrast in monotone display. The conventional text and line drawings are drawn differently from the metal surface, and even if the characters and figures expressed by such a drawing method are monotone, they can be clearly distinguished from the drawing on the metal surface. This is because the characters and figures being displayed stand out. Therefore, in this embodiment, characters and figures are drawn on the metal surface by simulating general metal processing so that these characters and figures are not conspicuous on the metal surface.

In this embodiment, characters 41a to 45a are drawn on each display 41 to 45 imitating a metal plate, imitating metal punching. These letters 41a to 45a have a blank space (character portion) in a dark color, and an edge portion of the metal plate visible around the space in a light color across the width of the plate thickness. The reason why the characters 41a to 45a are punched is that the characters 41a to 45a that are desired to be conspicuous are displayed in color as if they were illuminated from the back side of the metal plate (Fig. 4(b)). see 42a and 42c).

On the navigation button 42, the music button 43 and the picture button 44, figures 42b, 43b and 44b of "magnifying glass", "musical note" and "camera" are drawn to imitate etching. Drawing simulating etching processing can vary the expression of figures and the like by reproducing the degree of corrosion on the metal surface.

For example, FIG. 4(a) shows that the degree of corrosion of the metal surface is low, and the "magnifying glass", "musical note" and "camera" figures 42b, 43b and 44b appear as if they are slightly discolored on the metal surface. (actually looks like the figure in FIG. 15 or 16). In the case of a mode of expression in which the degree of corrosion of the metal surface is low, the figures 42b to 44b that are etched and the metal surface that is not etched have the same luster, hairlines, etc., and the figures 42b to 44b are transparent. should be visible.

In addition, as the degree of corrosion of the metal surface increases, the corroded portion becomes more deeply dented, and the appearance and properties of the corroded portion and the metal surface differ. For example, like the button representing the "map code" in FIG. 16, the corroded portion is recessed from the metal surface, and the surface becomes a dull, rough surface. If the degree of corrosion is made higher than this, the corroded portions will be expressed in the same manner as punching, such as characters 41a to 45a.

In this way, the lower the degree of corrosion on the metal surface, the less conspicuous the figure or the like drawn on the metal surface. It is possible to make a figure or the like drawn on the screen stand out. Therefore, for example, for buttons that are frequently used, graphics are drawn in an expression mode with a high degree of corrosion on the metal surface, and for buttons that are used infrequently, graphics are drawn in an expression mode with a low degree of corrosion on the metal surface. This makes it easier for the user to select buttons according to their needs.

<<Switching from monotone display to color display>>
On the menu screen shown in FIG. 4(a), the characters 41a to 45a of any of the navigation button 42, music button 43, picture button 44 and option button 45 are switched to color display according to the user's needs. This color display means display expressed using at least one chromatic color different from monotone display. For example, if monotone display is a grayscale consisting of achromatic colors such as white, gray, and black as in this embodiment, all chromatic colors correspond to color display. Also, if the monotone display is a display expressed by a single chromatic color shade or brightness, other chromatic colors having different hues correspond to the color display. A specific example of switching from monotone display to color display will be described below with reference to the menu screens shown in FIGS.

First, when the power switch 15 (see FIG. 1(b)) provided on the housing 11 of the navigation device 10 or the menu button (not shown) is pressed, a menu screen consisting of only monotone display shown in FIG. 4(a) is displayed. is displayed. As described above, the characters 41a to 45a included in the respective displays 41 to 45 of the menu screen are, in the state before the touch panel 13 is operated, a blanked dark space and bright edges bordering the space. Partially drawn. In such a menu screen, the background 41, the navigation button 42, the music button 43, the picture button 44, and the option button 45 are all expressed in achromatic shades or shades, so that these displays 41 to 45 are human-like. Stimulation given to color vision is the same, and there is no difference in visibility. Therefore, the user's eyes are not drawn to any of the displays 41, 42, 43, 44 or 45 in the menu screen.

Next, when the user touches, for example, the navigation button 42 in the menu screen via the touch panel 13, the characters 42a of the navigation button 42 are switched to color display as shown in FIG. See dotted line labeled 42c). In this embodiment, the letters 42a of "NAVI" formed by stamping the metal plate of the navigation button 42 are displayed in color as if illuminated from the back side with chromatic light.

Specifically, the characters 42a of "NAVI" are drawn as if they are emitting chromatic colors, and the area within the dotted line with reference numeral 42c is displayed in color. For example, the characters 42a of "NAVI" located at the center of the light emission may be drawn darker, and the light leaking from the periphery of the characters 42a may be drawn lighter, in the same chromatic color. Alternatively, only the characters 42a of "NAVI" may be drawn in a chromatic color so as to be self-luminous. The characters 42a of "NAVI" may be solidly painted in a chromatic color to give a texture different from that of the navigation button 42, which realistically reproduces the metal surface.

<<<action and effect>>>
Since the characters 42a of the navigation button 42 are switched to the color display in this way, among the displays 41 to 45 in the menu screen, the characters 42a have a stronger stimulus to the human color sense, and the user who has viewed the menu screen is more impressed. The eye can be drawn to the colored characters 42a. As a result, the user can recognize at a glance that the navigation button 42 has been effectively operated and the route guidance function of the navigation device is being executed.

In particular, in the navigation device 10 of the present embodiment, the displays 41 to 45 in the menu screen are drawn on a metal surface having an appearance and texture similar to the metal surface of the housing 11. The user can pinpoint and access necessary characters 42a in the display unit 12 without paying attention to unnecessary displays in the housing 11 or the menu screen when the unit 12 is viewed for a moment.

＜＜Option screen＞＞
Next, the option screen shown in FIG. 5 will be described as another display mode of the display unit 12 as an example. When the user touches the option button 45 in the menu screen shown in FIG. 4(a), the characters 45a of "OPTION" emit light in color display as in FIG. 4(b), and the display unit 12 switch to the option screen.

In FIG. 5, the option screen of this embodiment is composed of a background 51, three level operation sections 52, 52, 52, and a switch 53. In FIG. Unlike the menu screens of FIGS. 4A and 4B described above, the option screen of this embodiment includes color display in the monotone display from the initial state.

<<<Background>>>
The background 51 simulates the luster of a metal surface by rendering light reflections and shadows using the contrast between monotone display colors. Also, in this embodiment, the grid pattern 50 is drawn on the surface of the background 51 to make it look more like a metal surface. On this background 51, the title of this option screen and items that can be arbitrarily set by the user are displayed in colored characters 51a to 51e, respectively. Colored characters 51a to 51e are more stimulating to human color vision than monotone displayed metal surfaces, and can attract the eyes of the user viewing the option screen to these characters 51a to 51e.

Here, since the color-displayed characters 51a to 51e give the same stimulus to human color vision, there is no difference in visibility. Therefore, the user who sees the option screen searches for the item that he or she wants to change among the characters 51a to 51e. , no particular problem occurs.

<<<Level operation part>>>
The level operation unit 52 has a − button 52A and a + button 52C (hereinafter collectively referred to as “± buttons 52A and 52C”) arranged at the left and right ends of an indicator 52B. The ± buttons 52A and 52C imitate small mirror-finished metal plate buttons with a contrast difference in monotone display. The ± buttons 52A and 52C are provided with monotone "-" symbols 52a and "+" symbols 52c drawn to simulate punching or etching. The indicator 52B imitates a thin columnar metal bar, and its metal surface is mirror-finished like the ± buttons 52A and 52C by contrast of monotone display.

In this embodiment, the brightness of the level operation section 52 is set high, and the brightness of the background 51 is set low, so that the metal surfaces of the two have different appearances and textures. As a result, the smoothly shining mirror-finished level operation section 52 can be made conspicuous on the dark and heavy background 51 of the grid pattern. In the same manner as described above, the level operation section 52 may be either a 2D object or a 3D object. , the three-dimensional level operation section 52 can be conspicuous, and the operability of setting change can be improved.

The operation of the level operation section 52 will be described. When the user touches the ± button 52A or 52C via the touch panel 13, the monotone "-" symbol 52a or "+" symbol 52c is switched to color display. For example, the "-" symbol 52a or the "+" symbol 52c of the ± button 52A or 52C is displayed in color as if it were illuminated from behind with chromatic light. As indicated by reference numeral 52d in FIG. 5, the "-" symbol 52a is drawn as if it were emitting chromatic color, and the area within the dotted line is displayed in color.

Also, when the user touches the ± button 52A or 52C, the light emission 52b of the indicator 52B increases or decreases according to the number of touches or the duration of the touch. The line-shaped light emission 52b is a chromatic color display, and is conspicuous in contrast with the monotone display indicator 52B, the ± buttons 52A and 52C, and the background 51. FIG. The light emission 52b visually indicates the levels of “volume”, “luminance (daytime)” and “luminance (nighttime)” (see symbols 51ab to 51d in the figure) depending on its length, and is monotone. The color display during display makes it easy to visually recognize the change in the length.

Here, the light emission 52b may be at least a chromatic color different from monotone display, but in the present embodiment, the color scheme is devised in order to make the color display light emission 52b stand out more. For example, the light emission 52b may be color-coded into the central portion and the peripheral portion to provide a difference in brightness. In the example shown in FIG. 5, the central portion of the emitted light 52b is colored with high brightness, and the peripheral portion is colored with lower brightness than the central portion. Preferably, the central portion of the light emission 52b is white, which has the highest brightness, and the peripheral portion is a chromatic color with high saturation. can be made

<<<switch>>>
The selector switch 53 is for setting the display mode of "full map radar display" (see reference numeral 51e in the figure). Here, the "full map radar display" is a warning screen displayed on the map screen for the route guidance function, and displays a warning icon on the map when the vehicle approaches an object to be warned. , which informs the user of the position and type of the object to be warned (see the right half of the screen in FIG. 23). The display modes of such "full map radar display" include, for example, "always displayed mode" and "alarm display mode". There is a "normal" mode in which all items are displayed, and a "minimized" mode in which only the types of alarm targets are displayed.

The change-over switch 53 of the present embodiment imitates a horizontally long metal plate button with a contrast difference in monotone display. The change-over switch 53 displays characters 53a in a chromatic color display different from the monotone display color. Each time the changeover switch 53 is touched, the characters 53a are switched to, for example, "constant display", "alarm display (normal)", or "alarm display (minimized)", and "full map radar display" (Fig. 51e) is displayed. By displaying the characters 53a in color in the changeover switch 53 which is monotone, the characters 53a can be conspicuous and the visibility thereof can be further improved.

<<Keyboard Screen>>
Next, another display mode of the display unit 12 will be described by taking the keyboard screen shown in FIG. 6 as an example. When the user touches the navigation button 42 in the menu screen shown in FIG. 4(a), the characters 42a of "NAVI" are switched to color display, and the route guidance function is executed. The keyboard screen shown in FIG. 6 is used for inputting a destination and searching for keywords in the route guidance function.

In the figure, the keyboard screen of this embodiment consists of a keyboard body 61 imitating a metallic surface with monotone display, a plurality of key buttons 62, 62, 62, . 63. The keyboard body 61 has a stepped recess 61a formed by pressing a metal plate and a rectangular punched window 61b. Key buttons 62, 62, 62, . In this embodiment, the keyboard body 61 has a metal surface with a low lightness color, and each key button 62 has a metal surface with a high lightness color, so that each key button 62 stands out on the keyboard body 61 .

On each key button 62, monotone characters, symbols or graphics 62a, 62a, 62a, . . . are displayed by drawing imitating punching or etching. When the user touches each key button 62 via the touch panel 13, the characters, symbols, or figures 62a displayed in monotone are switched to display in color.

Here, the keyboard screen of the present embodiment adopts two different color display modes. In the first mode, as in the above-described embodiment, the characters and the like 62a of the key button 62 touched by the user are displayed in color as if illuminated from behind with chromatic light. For example, as indicated by reference numeral 62b in FIG. 6, the character 62a of "na" is drawn as if it is emitting chromatic color, and the area within the dotted line on the key button 62 is displayed in color. On the other hand, in the second mode, the entire key button 62 is drawn as if it were a transparent body, and the entire key button 62 touched by the user is displayed in color with an expression that allows chromatic light to pass therethrough and emits light. For example, as indicated by reference numeral 62c in FIG. 6, the entire key button 62 including the characters "determine" is drawn as if emitting light in a chromatic color, and the area within the dotted line on the background 61 is displayed in color. .

<<Map Screen>>
Next, the map screens shown in FIGS. 7 to 9 will be described as examples of other display modes of the display unit 12. FIG. When the destination is specified by the keyboard screen of FIG. 6 and the route to the destination is determined, route guidance is started on the color map screen shown in FIG.

<<<color display map screen>>> The map screen shown in FIG. is displayed. Details of the land elements of the map 70 and various icons on the map 70 are shown in FIGS. 11-13. Note that the map screen shown in FIG. 7 is a simplified map screen of an actual navigation device for convenience of explanation, and the land elements in FIG. 11 and the various icons in FIGS. 12 and 13 are actually used. These are just some examples of what is available.

7 and 11, the land elements forming the map 70 include a land area 71A, a high standard road 71B, a low standard road 71C and a destination route 71D. In the color display shown in FIG. 7, for example, the land 71A is color-coded and displayed for each predetermined area such as "pale yellow/pale pink/pale blue/pale green". For example, the high standard road 71B is displayed in "blue", and the low standard road 71C is displayed in "light blue" or "light brown". The destination route 71D indicates the route to the destination. For example, it is normally displayed in "green", and when the route is congested, it is displayed in "red". (See “Colors in Color Display”). 7, the land 71A, the high-standard road 71B, the low-standard road 71C, and the destination route 71D are all displayed as two-dimensional 2D objects (see FIG. 11). (see “Display Type” in ).

7 and 12, general icons displayed on the map 70 include, for example, a vehicle icon 72, a traffic light icon 73A, a destination icon (see FIG. 12), a highway icon 73B, a national road icon 73C. and a prefectural road icon 73D. In the color display shown in FIG. 7, for example, the own vehicle icon 72 is displayed in "red", the traffic light icon 73A is displayed in "green+yellow+red", and the destination icon 73B is displayed in "white+black". The expressway icon 73B, the national highway icon 73C, and the prefectural road icon 73D are all displayed in "blue+white" following the actual signs (see "colors displayed in color" in FIG. 12). 7, these vehicle icon 72, traffic light icon 73A, destination icon (see FIG. 12), expressway icon 73B, national road icon 73C, and prefectural road icon 73D are displayed in the same manner as in the conventional art. is also displayed as a planar 2D object (see “Display type” in FIG. 12).

7 and 13, facility icons displayed on the map 70 include, for example, a school icon 74A, a hospital icon 74B, a shrine icon 74C and a building icon 74D. Company icons 25 , 25 , 25 . In the color display shown in FIG. 7, for example, the school icon 74A is displayed in "green+white", the hospital icon 74B is displayed in "white+black", the shrine icon 74C is also displayed in "white+black", and the building icon 74D is displayed in "gray". be done. Further, each company icon 25 is displayed in the color of the logo determined by each company (refer to "colors displayed in color" in FIG. 13). In the color display shown in FIG. 7, these facility icons 74A to 74D and each company icon 25 are all displayed as two-dimensional 2D objects as in the conventional art (see "display type" in FIG. 13).

7 and 14, the alarm icons displayed on the map 70 include, for example, a loop coil icon 76A, an LH system icon 76B, a new H system icon (see FIG. 14), a radar orbis icon 76C, an inspection area Included are POI icons such as icon (see FIG. 14), enforcement area icon (see FIG. 14), N system icon (see FIG. 14), accident hot area icon 77, and the like. Note that these POI icons are only examples, and the alarm icons displayed on the map 70 include a wide range of icons indicating position information of predetermined objects (or target areas) that need to be notified to the user.

In this embodiment, the POI icons described above are grouped into warning, warning, and notification according to the degree of urgency of the object to be alerted, and the icons are color-coded for each group. In the color display shown in FIG. 7, for example, the loop coil icon 76A, the LH system icon 76B, the new H system icon, and the radar type orbis icon 76C all belong to the alarm group and are displayed in "red+white". Both the checkpoint area icon and the control area icon belong to the warning group and are displayed in "yellow + white". Both the N system icon and the accident-prone area icon 77 belong to the notification group and are displayed in "blue and white" (see "colors in color display" in FIG. 14). Further, in this embodiment, during the color display shown in FIG. 7, each POI icon described above is displayed as a planar 2D object as in the conventional art (see "Display type" in FIG. 14). .

<<<Monotone map screen>>>
On the color map screen shown in FIG. 7, when the vehicle approaches the warning object within a predetermined distance, the screen of the display unit 12 is switched to the monotone map screen shown in FIG. In this embodiment, unnecessary information is omitted, only the information necessary to perform the alarm function is displayed on the screen, information that is particularly necessary is highlighted in color to perform the alarm function, and other information is displayed. is displayed in monotone. It should be noted that the "information required to perform the warning function" in the present embodiment is information required to notify the user of matters related to the warning object. Such a monotone display map screen will be described below with reference to FIG.

<<<<Omission of display>>>>
First, when the color display map screen shown in FIG. 7 is switched to the monotone map screen shown in FIG. 8, unnecessary information for performing the alarm function is omitted. In this embodiment, text characters on the map 70 shown in FIG. 7, facility icons 74A to 74D unrelated to the course of the own vehicle (destination route 81D), and company icon 75 are omitted from the screen, and the map shown in FIG. The information displayed on 80 is simplified.

Whether or not the display can be omitted when switching to the monotone display map screen shown in FIG. 8 is exemplified in the "Display Omission" column of FIGS. For example, for the land elements of the map shown in FIG. 11, "land" and "destination route" are not omitted (see reference numerals 81A and 81D in FIG. 8). This is because the destination route 81D indicates the current course of the own vehicle during execution of the route guidance function, and is necessary to inform the user of warning objects on the course. Also, the land 81A is the background of the road along which the vehicle travels, and although it is of low importance as information, it is necessary for constructing the map screen. On the other hand, "high standard road" and "low standard road" may be omitted as long as they are not the course of the vehicle. Also, as shown in FIG. 8, a road 81C that intersects the course of the vehicle and a road 81C that is adjacent to the course of the vehicle may be useful for grasping the position of the vehicle, so the display should not be omitted. may

For example, the general icons on the map shown in FIG. 12 may be omitted except for the own vehicle icon 81D indicating the position of the "own vehicle". However, it is not necessary to omit the display of icons useful for grasping the position of the own vehicle or the alarm target (see reference numeral 83A in FIG. 8). Also, the display of the "destination" icon may not be omitted while the route guidance function is being executed.

For example, the facility icons and company icons on the map shown in FIG. 13 are unnecessary information for performing the alarm function, so the display may be omitted entirely. However, as in the present embodiment, the facility icons and company icons along the destination route 81D, which is the course of the own vehicle, are useful for ascertaining the position of the own vehicle or the alarm target object, so the display should not be omitted. (see numeral 75 in FIG. 8).

For example, the warning icon on the map shown in FIG. 14 may be omitted if it is not located on the course of the own vehicle or near the own vehicle. However, as in this embodiment, all alarm icons that can be displayed on the scale of the current map 80 may be displayed (see reference numerals 86A to 86C and 87 in FIG. 8).

<<<<map display mode>>>>
In FIG. 8, the monotone display map screen according to the present embodiment includes a land area 81A, a low-standard road 81C necessary for fulfilling the warning function, a destination route 81D (high-standard road 81B), an own vehicle icon 82, and a traffic light icon. 83A, a company icon 75, and all alarm icons 86A-86C, 87 that can be displayed at the current map 80 scale.

Of these displays, the land 81A, the low-standard road 81C, and the traffic light icon 83A are monotone displays expressed in single-color shading or brightness. Alarm icons 86A to 86C and 87 are displayed in chromatic colors different from monotone display.

First, the constituent elements of the monotone display in FIG. 8 will be described. In this embodiment, the land 81A and the low-standard road 81C, which are the land elements of the map 80, are 2D objects with an appearance imitating a metal surface. The land 81A is a drawing imitating the color, gloss, and surface treatment of the metal surface (for example, unpainted aluminum) of the housing 11 shown in FIG. It is difficult to distinguish from the land 81A. In addition, the low-standard road 81C is drawn on the metal surface of the land 81A by simulating an etching process, and is displayed on the land 81A simulating the metal surface so as not to cause a sense of incompatibility.

If the general icons such as "signal", "destination", "highway", "national road" and "prefectural road" shown in FIG. Make it visible and discreet. The same applies when facility icons such as "school", "hospital", "shrine" and "building" shown in FIG. 13 are not omitted. In addition, when these icons are displayed in grayscale, they are drawn in an expression that imitates metal unevenness processing or punching processing by etching or the like, so that the display is less likely to cause discomfort on the land 81A. 12 and FIG. 13 "Colors in Monotone Display").

Next, the constituent elements of the color display in FIG. 8 will be described. In this embodiment, the destination route 81D is displayed in the same manner as the light emission 52b of the indicator 52B shown in FIG. That is, the destination route 81D imitates a line-shaped light emission that extends along the course of the own vehicle. are also colored with low lightness (for example, “blue”, “green”, “red” or “purple”). The destination route 81D imitating this light emission is a two-dimensional 2D object, and it looks like the highway 81B drawn by simulating punching on the metal surface of the land 81A is illuminated from the back side with chromatic light. The representation is color-coded.

The own vehicle icon 82 changes from the 2D object shown in FIG. 7 to the 3D object shown in FIG. 8 (see "Display type" in FIG. 12). The own vehicle icon 82, which is a 3D object, draws itself in a red arrow-shaped three-dimensional shape, has a height difference with the metal surface of the land 81A, and draws as if it is floating on the luminous destination route 81D.

Each of the warning icons 86A to 86C, 87 is also changed from the 2D object shown in FIG. 7 to the 3D object shown in FIG. 8 (see "Display type" in FIG. 12), like the vehicle icon 82 described above. Each of the warning icons 86A to 86C and 87 of the 3D object draws itself in a spherical three-dimensional shape, has a height difference with the metal surface of the land 81A, and is displayed on the land 81A, the high standard road 81B, the low standard road 81C, or the destination. It is drawn as if it is floating on the route 81D. Regarding the height difference in the screen, the land 81A is displayed at the lowest position, the warning icons 86A to 86C and 87 are displayed at the middle position, and the vehicle icon 82 is displayed at the highest position. Therefore, the own vehicle icon 82 can pass over each of the warning icons 86A to 86C and 87 displayed on the destination route 81D. Further, each of the alarm icons 86A to 86C and 87 is rotated in one direction on the map 80 as indicated by the arrows in FIG. ing.

In this embodiment, the company icon 75 along the destination route 81D is displayed without omission. When the company icon 75 is not omitted, it is displayed in the color of the logo determined by each company, as in FIG.

<<<Example of change to monotone map screen>>>
FIG. 9 shows a modified example of the monotone display map screen of FIG. 8 described above. The map screen shown in FIG. 9 has a configuration in which less necessary information is omitted from the above-described monotone display map screen in FIG. there is

On the color map screen shown in FIG. 7, when the vehicle approaches the warning object within a predetermined distance, the screen of the display unit 12 is switched to the monotone map screen shown in FIG. In the map screen shown in FIG. 9, only the destination route 81D, the own vehicle icon 82, and the nearest alarm icon 86A are displayed in color on a monotone display map 80 imitating a metal surface, and the other icons shown in FIG. Omit everything.

Also, the map 80 and the destination route 81D are displayed as 2D objects, and only the vehicle icon 82 and the most recent alarm icon 86A, which are particularly necessary, are displayed as 3D objects on these 2D objects. Further, the warning icon 86A of the 3D object is rotated on the map 80 in the direction of the arrow in the drawing, and strongly attracts the user's eye on the monotone display map 80 imitating a metal surface.

According to such a map screen of the present embodiment, only the minimum information 81D, 82 and 86A necessary for notifying the nearest warning target on the course of the own vehicle is displayed on the monotone map 80 in color. Since it is configured to display, even a user who is driving a motorcycle can access the necessary information 81D, 82 and 86A on the screen with pinpoint accuracy, and can determine the positional relationship between the own vehicle and the nearest alarm object. It is possible to grasp at a glance.

<<<Other changes to the monotone map screen>>>
Each of the above-described embodiments of FIGS. 8 and 9 exemplifies the case where the map 80 is displayed in monotone when the navigation device 10 issues an alert, but the display mode of the present invention is limited to an alert. not to be For example, as shown in FIG. 10, the navigation device 10 may switch the map from color display to monotone display when guiding the vehicle to the destination.

During execution of the route guidance function, the navigation device 10 displays a detailed map including land elements, general icons, facility icons, and company icons in color until the vehicle approaches a left or right turn point ( See Figure 7). Thereafter, when the vehicle approaches the left or right turn point within a predetermined distance, the detailed color map is switched to a monotone map 90 shown in FIG.

The map 90 of FIG. 10 has a configuration in which high standard roads 91B and low standard roads 91C are displayed by drawing simulating etching processing on land 91A simulating a metal surface, as in the embodiments of FIGS. All of these components are represented as monotone 2D objects. A destination route 91D, an own vehicle icon 92, and a flag icon 93 are displayed in color on the map 90 displayed in such a monotone display. The destination route 91D is a 2D object imitating linear light emission extending along the course of the own vehicle, and the car icon 92 and the flag icon 93 are 3D objects.

In this embodiment, for example, a flag icon 93 such as "red" or "yellow" is displayed at the right turn point of the own vehicle, and the flag icon 93 is blinked to make it stand out. In addition, in this embodiment, in order to make the right turn point of the own vehicle easier to understand, as in the embodiment of FIG. 9, all less necessary land elements, general icons, facility icons, and company icons are omitted. There is.

As described above, on the map screen of the present embodiment, the destination route 91D that is the course of the own vehicle, the own vehicle icon 92 that indicates the position of the own vehicle, and the flag icon 93 that indicates the right turn point of the own vehicle. Only the minimum information required to inform the user of the right turn point is displayed in color on the monotone display map 90 . As a result, the right turn point on the map 90 can be grasped at a glance, and the actual positional relationship between the traveling own vehicle and the right turn point becomes clear.
