The conventional colorful and colorful display as described above is realistic, familiar, and easy to see, so it suits the tastes and conveniences of many users such as families. On the other hand, the inventors have found that they lack luxury, near future, and coolness, and do not suit the tastes of some users, such as those who are in sports cars and singles. I found it. Further, the present inventors have found that the conventional colorful and colorful display does not match an interior based on monotone or an interior with a sense of the near future as in a luxury car or the like. In addition, electronic devices that display information such as maps in monotone are known (Patent Document 2), but monotone display is like a black-and-white television, and it is possible to obtain a sense of luxury, a sense of the near future, and coolness. There was a problem that it could not be done and it did not match the interior of luxury cars.

The present application discloses inventions that address all or part of the above problems or other problems.

The present application discloses, for example, the inventions described in the following configuration examples.

<Structure example 1>
An electronic device that is equipped with a control means for displaying an image on a screen display unit and can be installed in a vehicle so that a person in the vehicle can visually recognize the display unit.
The control means is an electronic device having a sci-fi two-tone display function, which is a function of displaying the image in two-tone.

In this way, the user can display a screen that has a sense of luxury, a sense of the near future, and a sense of coolness, and a screen that suits the tastes of the user group such as those who are in sports cars and singles. And / or the user can feel that he / she is displaying an image screen that matches the interior of a luxury car. The two-tone display may be a display expressed by two chromatic shades and light and dark.

The two-tone display may be a display expressed by achromatic shades of white, black, and ash and light and shade in addition to the two chromatic shades and light and shade. In this way, it is possible to perform an easy-to-see display using white, black, and gray, which are highly distinguishable for the two chromatic colors, in the screen image having a sense of quality, a sense of the near future, and a coolness.

The inventors have found that if the above two chromatic colors are green and blue, it is possible to express a sense of luxury, a sense of the near future, and coolness more strongly. The inventors, etc., assume that the two-tone display is represented by the light and darkness of green, blue and its mixed color, or the light and darkness of green, blue and its mixed color and white, black, and gray. We found that it is good to express the feeling of the future and coolness particularly strongly, and it is good to express the feeling of luxury, the feeling of the near future and the coolness more strongly by lowering the brightness of green, blue and their mixed colors.

The inventors have also found that it is good not to use red in the image screen or to reduce the use of red as much as possible because it is possible to express a sense of luxury, a sense of the near future, and coolness more strongly. The inventors have also found that it is good to use the above two chromatic colors as cool colors because they can express a sense of luxury, a sense of the near future, and coolness more strongly. The inventors should also avoid using warm colors in the screen image, or reduce the use of warm colors as much as possible so that a sense of luxury, a sense of the near future, and coolness can be expressed more strongly. I found. The inventors also express a sense of luxury, a sense of the near future, and coolness more strongly by not using primary colors and / or pastel colors in the image screen, or by using as few primary colors and / or pastel colors as possible. I found it good because I could do it. The inventors have also found that lowering the brightness of an image is good because it can express a sense of luxury, a sense of the near future, and coolness more strongly.

The electronic device may be an in-vehicle electronic device such as a navigation device or a radar detector that is installed and used in a vehicle. The screen display unit may be a screen such as an LCD (Liquid Crystal Display), an organic ELD (Organic Electroluminescent Display), or a CRT (Cathode Ray Tube). The control means may be a computer having a storage device such as a CPU and RAM.

<Structure example 2>
The image displayed by the sci-fi two-tone display function includes a background and a button.
An electronic device characterized in that the brightness of the button is made higher than that of the background.

By doing so, the user can feel that the button is raised, and the user can feel that the image has a three-dimensional effect and that the image has a strong sense of the near future. Since it is normal for an object to be farther away to appear darker, the present inventor has found that by making the brightness of the button higher than that of the background, it is possible to create a three-dimensional image in which the button appears to be raised. .. Also, in this way, the buttons can be made to stand out. The background may be the background of the button.

<Structure example 3>
The image displayed by the two-tone sci-fi display function includes a background and a button.
The button is an electronic device characterized in that it is translucently arranged on a layer on the front side of the background.

In this way, the sense of the near future can be further strengthened. For example, the image displayed by the two-tone sci-fi display function may be an image with an alpha channel, and the button may be displayed semi-transparently by setting the alpha value of the button to an appropriate value between 0% and 100%. The background may be the background of the button.

For example, if the background of the configuration examples 2 and 3 is a map, the electronic device may function as a navigation device or a radar detector. If the backgrounds of the configuration examples 2 and 3 are, for example, a design including a world map, the image can be a menu screen with a sense of the near future and coolness. The buttons of the configuration examples 2 and 3 may be configured so that the electronic device executes the function assigned to the buttons when the buttons are operated by the user. The image may be composed of a plurality of layers. It is preferable that the layer for drawing the background and the layer for drawing the button are separate layers, and the layer for drawing the button is arranged on the front side of the layer for drawing the background.

<Structure example 4>
An electronic device characterized in that the background is an image drawn by using perspective.

By doing so, the buttons appear to be floating in the air on the front side of the three-dimensional background, and the image can be created with a strong sense of the near future and coolness. The background drawn using the perspective method may be drawn using the perspective method at the time of drawing. For example, the background drawn using the perspective method may be one drawn by calculation at the time of drawing, such as CG, but the background drawn using the perspective method in advance can be stored as a storage means in a format such as a bitmap. The memorized one may be read out and displayed.

<Structure example 5>
The image displayed by the two-tone sci-fi display function includes a plurality of display elements.
An electronic device, wherein the plurality of display elements include a light emitting display element, which is a display element having a high central brightness and a lower brightness as the distance from the center increases.

By doing so, it is possible to make the user feel that the light emitting display element is shining, and it is good that the near future feeling of the image can be enhanced. A point light source, a line light source, etc. are brightest in the center and become darker as the distance from the center increases. Therefore, by changing the brightness of the light emitting display element in the same manner, light is emitted as if the light emitting display element is a light source. It is good because the user can feel that the display element itself is emitting light. For example, when the image displayed by the two-tone sci-fi display function includes a map, the roads in the map, the characters and patterns on the display elements such as buttons and icons on the map, and the outlines and frames of these display elements are emitted. It is good to say. When the road in the road map is used as a light emitting display element, it is particularly preferable because the road looks like it is emitting light and the feeling of the near future is enhanced.

<Structure example 6>
The control means
A color display function that displays the image in color,
An electronic device further comprising a display switching function for switching between a display by the two-tone sci-fi display function and a display by the color display function according to a user's operation.

In this way, the user can select the display of the image by the two-tone display function and the display of the image by the color display function according to his / her taste, so that it is possible to provide an image that suits the taste of a wider user group. .. The color display may be, for example, a multicolored display using all of RGB or a colorful display. For example, in the case of an electronic device that displays a map of the place where the user is currently driving as an image, such as a navigation device, two-tone when driving on a road that the user is accustomed to or an area that the user is familiar with. By displaying the image, it is possible to create an image that matches the interior of the user's vehicle. On the other hand, when the user is driving on a land that the user is not familiar with, the color display should be realistic and easy to understand. Therefore, it becomes easy to grasp the information of the unfamiliar land.

<Structure example 7>
The image displayed by the two-tone display function and the color display function includes a background and icons arranged on a layer on the front side of the background.
The color display function makes the icon opaque and arranges it on the background.
The two-tone display function is an electronic device characterized in that the icon is made transparent and arranged on the background.

In this way, the amount of information provided to the user is increased by displaying the icon in the image displayed by the color display function, while the icon is made transparent in the image displayed by the two-tone sci-fi display function. Is good because it becomes simple.

In particular, when the icon is colorful and / or colorful, it may be possible to prevent the icon from impairing the high-class feeling, near-future feeling, and coolness of the image. For example, if the background is a map and the map display software (programs and data) incorporates colorful and colorful icon data, the icon drawing process of the map display software will not be changed. , The icon can be hidden just by making the icon transparent. When the background is a map, for example, if the icon indicates a school, kindergarten, nursery school, post office, fire department, police station, factory, shrine, temple, parking lot, company, etc., the color display function displays the icon on the map. It is good to be able to display the location of these facilities with.

For example, the image displayed by the two-tone sci-fi display function and the color display function is an image with an alpha channel, the alpha value is set to 100% when the icon is transparent, and the alpha value is 0 when the icon is opaque. It should be%.

The color display function in the configuration example 7 may be omitted. For example, the following configuration example 7-1 may be used.
<Structure example 7-1>
The image displayed by the sci-fi display function includes a background and icons arranged on a layer on the front side of the background.
The two-tone display function is an electronic device characterized in that the icon is made transparent and arranged on the background.

In this way, for example, if the background is a map and the map display software (program or data) incorporates colorful and colorful icon data, the icon of the map display software is drawn. It is good because the icon can be hidden just by making the icon transparent without changing the process. For example, it is preferable to adopt the configuration example 7-1 in any of the configuration examples 1 to 5.

<Structure example 8>
The icon belongs to one of the first and second categories.
The two-tone sci-fi display function
The icons belonging to the first category are made transparent and placed on the background.
An electronic device in which the icon belonging to the second category is made opaque and placed on a background.

By doing so, it is sufficient that the decrease in the amount of information of the image displayed by the two-tone sci-fi display function can be reduced. For the color display function, for example, both the icons of the first category and the second category may be opaquely arranged on the background.

For example, icons with colorful and colorful color schemes, icons for which changing the default display color is prohibited or unfavorable are classified into the first category, and other icons are classified into the second category. It is good to do it. For example, in the case of an image including a map, the company icon indicating a company such as a gas station, a restaurant, a hamburger shop, a convenience store, a bank, etc. is a reproduction of the company logo design, and the color defined by each company is Since it cannot be changed to a different color, these company icons are categorized into the first category and other, for example, schools, kindergartens, nurseries, post offices, fire departments, police stations, factories, shrines, temples, parking lots. It is advisable to classify the icons indicating the above into the second category.

<Structure example 9>
The image displayed by the two-tone sci-fi display function and the color display function includes a map drawn based on map data including first and second types of roads.
The color display function displays the first and second types of roads on the map.
The two-tone sci-fi display function is an electronic device characterized in that the first type of road is displayed on the map and the second road is not displayed.

In this way, the image displayed by the two-tone display function can be made into a high-class, near-future, and cool image, and the map displayed by the two-tone display function can be simplified. Is good because it makes the map easier to see. For example, the first type of road may be an expressway or a highway, and the second type of road may be a narrow street. For example, the second type of road may be a narrower road than the first type of road. For example, the first type of road may be a more major road than the second type of road.

Further, the navigation screen and the guidance screen displayed by the two-tone display function include a plurality of display elements, and the plurality of display elements include a narrow street which is a display element having a high brightness in the center and a low brightness as the distance from the center increases. Therefore, the user feels that the narrow street is shining, and the image can be enhanced in the near future. Point light sources, line light sources, etc. are the brightest in the center and become darker as the distance from the center increases. good. For example, the image displayed by the two-tone display function includes a map, and the roads in the map, the characters and patterns on the display elements such as buttons and icons on the map, and the outlines and frames of these display elements are displayed by light emission. It should be an element. If the road in the road map is used as a light emitting display element, the road looks like it is emitting light, and the sense of the near future is enhanced.

The control unit 31 further has a color display function for displaying an image in color, and a display switching function for switching between a display by the two-tone display function and a display by the color display function according to a user's operation. Therefore, the user can select the display of the image by the two-tone display function and the display of the image by the color display function according to his / her taste, so that an image suitable for the taste of a wider user group can be provided. The color display may be, for example, a multicolored display using all of RGB or a colorful display. For example, when driving on a road that the user is accustomed to driving or in an area that the user is familiar with, the user can use the two-tone display to create an image that matches the interior of the user's vehicle, while the user can display the image. When the user is traveling on an unfamiliar land, the user can easily grasp the information of the unfamiliar land by making the display realistic and easy to understand in color display.

The image displayed by the two-tone display function and the color display function includes the map icon arranged in the background and the layer on the front side of the background, and the color display function makes the map icon opaque and arranges it on the background, and the two-tone display function. It is recommended to make the map icon transparent and place it on the background. By doing so, the amount of information provided to the user can be increased by displaying the map icon in the image displayed by the color display function, while the map icon can be made transparent in the image displayed by the two-tone display function. It's good because the image is simple.

In particular, when the map icon is colorful and / or colorful, it may be possible to prevent the map icon from impairing the high-class feeling, near-future feeling, and coolness of the image. For example, if the background is a map and the map display software (programs and data) contains data for map icons with colorful and colorful colors, change the map icon drawing process of the map display software. It is good because the map icon can be hidden just by making the map icon transparent. When the background is a map, for example, if the map icon is a map icon indicating a school, kindergarten, nursery school, post office, fire department, police station, factory, shrine, temple, parking lot, company, etc., the color display function is displayed. It is good to be able to display the location of these facilities on the map.

In addition, the image displayed by the two-tone display function and the color display function is an image with an alpha channel, the alpha value is set to 100% when the map icon is transparent, and the alpha value is set when the map icon is opaque. It is good because it is set to 0%.

Further, the image displayed by the sci-fi display function includes the background and the map icon arranged in the layer on the front side of the background, and the two-tone display function may make the map icon transparent and arrange it on the background. In this way, for example, if the background is a map and the map display software (programs and data) incorporates the data of the map icons with colorful and colorful colors, the map icons of the map display software. The map icon can be hidden by simply making the map icon transparent without changing the drawing process of.

In addition, the map icon belongs to either the first or second category, and the two-tone display function makes the company icon, which is a map icon belonging to the first category, transparent and arranges it on the background, and the second category. The general facility icon, which is a map icon belonging to, is made opaque and placed on the background. Therefore, it is sufficient that the decrease in the amount of information of the image displayed by the two-tone display function can be reduced. The color display function may be such that the map icons of both the first and second categories are opaque and placed on the background.

We classify colorful and colorful icons and company icons that are prohibited or unfavorable to change the default display color into the first category, and other general facility icons into the second category. It is good because it is classified. For example, a company icon indicating a company such as a gas station, a restaurant, a hamburger shop, a convenience store, or a bank is a reproduction of the company logo design and may be changed to a color different from the color set by each company. Since it is not possible, these map icons are classified into the corporate icon category, and other icons such as schools, kindergartens, nursery schools, post offices, fire departments, police stations, factories, shrines, temples, parking lots, etc. are general facilities. It is good because it is classified into the icon category.

The navigation screen and the guidance screen displayed by the two-tone display function and the color display function include a map drawn based on the map data including the first and second types of roads, and the color display function is the first on the map. And the second type of road may be displayed, and the two-tone display function may display the first type of road on the map and not display the second type of road.

In this way, the image displayed by the two-tone display function can be made into a high-class, near-future, and cool image, and the map displayed by the two-tone display function can be simplified. Is good because it makes the map easier to see. For example, the first type of road may be an expressway or a highway, and the second type of road may be a narrow street. For example, the second type of road may be a narrower road than the first type of road. For example, the first type of road may be a more major road than the second type of road.
