  The present invention relates to a multi-view display control device and a multi-view display control method.

2. Description of the Related Art Conventionally, multi-view display devices that display different screens according to two or three angle ranges with respect to the display surface of a display panel are known. Patent Document 1 describes a technique for adjusting the viewing angle in such a multi-view display device. In Patent Document 2, in the situation where one screen (for example, the screen on the driver's seat side of the vehicle) and the other screen (for example, the screen on the front passenger's seat) are displayed on the multi-view display device, When a user viewing the screen performs an operation on the screen, the operation is distinguished from an operation on the latter screen, thereby preventing an unintended screen transition of the user viewing the latter screen. The technology is described. Non-Patent Document 1 discloses a technique for simultaneously displaying three videos / contents in a triple-view liquid crystal display device.
JP 2006-184900 A JP 2006-195460 A “Development of“ Triple View LCD ”, the industry's first 3 video / content display”, [online], September 27, 2006, Sharp Corporation, [October 30, 2006 search], Internet <URL: http://www.sharp.co.jp/corporate/news/060927-a.html>

  In conventional technology, for example, when a display device having a triple view function is mounted on a vehicle, route guidance information is displayed on the screen for the driver's seat, a search screen for tourist spots and gourmet spots on the screen for the passenger seat, The triple view function was used for the purpose of displaying different contents on each screen such as DVD and TV images on the screen for the rear seats. In such a case, when the passenger in the rear seat wants to know the route guidance information displayed on the screen on the driver's seat side, the route guidance information should be visually recognized if the driver seat side screen is moved to an angle range that can be seen. However, if it is from the rear seat, there is a problem that the information displayed on the screen on the driver's seat side is difficult to see at a glance. When the multi-view display device is installed in the center of the dashboard, the distance between the multi-view display device and the rear seat is farther than the distance between the multi-view display device and the driver's seat. This is because even the information of the degree of detail looks small and fine from the rear seat. That is, in the past, attention has been paid to the fact that the angles of the lines of sight of the plurality of users with respect to the display surface are different, but in addition to the differences in angle, attention is paid to the case where the distances between the plurality of users and the display surface are also different. It wasn't.

  The present invention has been made in view of the above problems, and provides a technique capable of easily providing information that guides a user near a screen to a user far from the screen in a multi-view display device. For the purpose.

  In order to achieve the above object, in the present invention, first information to be guided in the first angle range is acquired, and a screen corresponding to the first angle range is displayed based on the first information. The second information to be guided in the second angle range different from the one angle range is selected from the first information, and the screen corresponding to the second angle range is displayed based on the second information. ing. According to this configuration, the user in the second angle range can visually recognize the second information selected from the first information without moving to the first angle range. Furthermore, since the second information is information selected from the first information for the user in the second angle range, information appropriate for the user in the second angle range is guided with an appropriate level of detail. can do.

In the present invention, the information acquisition unit may have at least a function of acquiring the first information.
The information displayed on the screen corresponding to the first angle range (hereinafter referred to as the first screen) by the first display control means is included in the first information and is at least a part of the first information. All of the first information may be used. Included in the first information is at least a part of the first information, which is information acquired for the user in the first angle range, but it is directly on the first screen. This means that information that is not displayed or information that is not displayed at a certain timing is included.
The second information selected by the information selection means is included in the first information and is at least a part of the first information.
The information displayed on the screen corresponding to the second angle range (hereinafter referred to as the second screen) by the second display control means indicates the second information itself, but is displayed on the second screen at a time. The information is not limited to being all of the second information.

  The multi-view display means only needs to be able to display different screens according to a plurality of angle ranges with respect to the display surface of the display panel, and may have a dual view function or a triple view function. The angle range section of the viewing angle with respect to the display surface may be 4 or more. When the dual view function is provided, it is assumed that the user in one angle range is farther away from the display surface than the user in the other angle range. When the triple view function is provided, it is assumed that the distance between the user and the display surface in at least one of the three angle ranges is different. A case may be assumed in which the distance between the user in the three angle ranges and the display surface are all different.

  Further, in the present invention, the first information may be route guidance information for a driver sitting in the driver's seat of the vehicle, and the information selecting means is information displayed on the first screen among the route guidance information. May be selected as the second information for the passenger sitting in the rear seat of the vehicle. In the present invention, the driver's seat and the rear seat are located on the display surface side of the display panel of the multi-view display device, and the following discussion will proceed on the assumption that the rear seat is located farther from the display surface than the driver's seat. A passenger in the rear seat who is a non-driver may want to know the route guidance information while the vehicle is traveling, but often does not necessarily need the route guidance information with the level of detail required by the driver. Further, since it is far from the display surface than the driver's seat, if a lot of information is displayed at a time and each piece of information is small and small, it is difficult to see from the rear seat. By extracting a part of the information displayed on the screen for the driver and displaying it on the screen for the passenger in the rear seat, a lot of information having the same level of detail as the information for the driver can be obtained at once. Compared to displaying on the screen, it is easier for the passengers in the rear seat to recognize the display content on the screen at a glance. Also, for example, when displaying a map in the same range as the map displayed on the driver's seat screen on the rear seat screen, the amount of information can be reduced by not displaying narrow roads or detailed place names. It may be less. When the amount of information is small, it is easy to grasp the information displayed on the screen at a glance even if it is far from the display surface.

  The information sorting means may sort information including at least information that is not displayed on the first screen among the route guidance information as second information for the passenger sitting in the rear seat of the vehicle. According to this configuration, even in the route guidance information acquired for the driver, even if the information is not directly displayed on the driver's screen at that time, the information including at least the information is included in the rear seat. Can be guided to passengers. For example, when a map of the current location of the vehicle and a narrow area around it is displayed on the driver's side screen, a map including the route from the departure point to the destination point on the rear seat side screen and the vehicle on that route When the current location is displayed, the passenger in the rear seat can intuitively grasp the ratio of the remaining route (route from the current location to the destination location) with respect to the entire route from the departure location to the destination location. Also, for example, when a map of the current location of the vehicle and its surrounding narrow area is displayed on the driver's side screen, for example, a destination and its surrounding map other than the range of the narrow area are displayed on the screen of the rear seat side. May be.

  In addition, the information selection means is adapted for a part of the route guidance information that is displayed on the first screen and information that is not displayed on the first screen for passengers sitting in the back seat of the vehicle. You may select as 2nd information. According to this configuration, a part of the information displayed on the driver's screen is extracted, information not displayed on the driver's screen is added, and the information is displayed on the rear seat's screen. Can do. Therefore, except for information that is displayed on the driver's screen but less useful for passengers in the rear seats, information that is not displayed on the driver's screen but that is highly useful for passengers in the rear seats. In addition, the passenger can be guided.

  Further, the information selection means includes a departure point and a destination point, and route guidance information for the driver including facilities and points around the route from the departure point to the destination point and the road type of the road in the route. To select information on at least one of the facility where the passenger may get off and the nearest point where the road type of the road on which the vehicle is traveling will change as the information for the passenger. Also good. The road type refers to a type such as an expressway, a general national road, and a main local road. For example, when the host vehicle is traveling on an expressway, the distance to the interchange (IC), junction (JCT), and service area (SA) existing on the driver's seat screen, and the expected transit time are determined by the host vehicle. When a predetermined number of items are displayed in order from the closest distance to the vehicle, the SA and the own vehicle get off on the general road except for the IC and JCT that only pass through the screen on the rear seat side even if the distance is close to the own vehicle. The distance to the scheduled IC and the expected passage time may be displayed. Furthermore, information indicating the type of service provided by the SA may be added and displayed. In this way, except for information that is not useful for passengers who are non-drivers, such as the distance and time to the IC and JCT that just pass, how much time is left to get to the SA where you can get off the vehicle and take a break It is possible to provide information that is highly useful to passengers, such as whether it is necessary, what kind of equipment is in the SA, and how long it is to get off the general road.

  Further, the second display control means displays a screen corresponding to the second angle range in a display mode having a higher visibility from a long distance than a display mode of information on the screen corresponding to the first angle range. You may let them. When the same information displayed on the first screen is displayed on the second screen, the information displayed on the second screen is more distant than the information displayed on the first screen. The display mode is changed so that the visibility from the screen becomes higher. For this reason, the user who views the second screen from a distance can easily view the information displayed on the second screen. Here, the visibility can be evaluated by various indices. For example, if the area for displaying a specific amount of information is large, it can be said that the visibility is high.

  In the present invention, the second display control means may enlarge and display the screen components displayed on the first screen on the second screen. According to this configuration, the screen components displayed based on the same information are larger on the screen on the rear seat side than those displayed on the screen on the driver's seat side, so the rear part far from the display surface is displayed. The passengers in the seat can easily recognize the information that the driver can know at a glance.

Further, the second display control means may display the line in the second screen thicker than the line in the first screen. According to this configuration, it is easy for the passenger in the rear seat far from the display surface to recognize the content of the information configured by the line displayed on the screen on the rear seat side.
Further, the second display control means may display the characters in the second screen larger than the characters in the first screen. According to this configuration, it is easy for the passenger in the rear seat far from the display surface to recognize the content of the characters displayed on the screen on the rear seat side.

  Further, the second display control means may classify the second information into a plurality of groups, and switch and display the information of the groups in order every predetermined time. According to this configuration, in order to guarantee the easy-to-see visibility for the passengers in the rear seats, even if the second information is not displayed on the screen on the rear seat side at once, By classifying the information into a plurality of times and displaying the set of information every time a predetermined time elapses, it is possible to guide information that is highly useful to the passengers in the rear seats while ensuring ease of viewing.

  As in the present invention, the first information to be guided in the first angle range of the multi-view display is acquired and displayed on the first screen based on the first information, which is different from the first angle range. The method of selecting information to be guided in the second angle range from the first information and displaying it on the second screen based on the second information is also applicable as a program or method for performing this multi-view display control. is there. In addition, the multi-view display control device and method as described above may be realized as a single device, or may be realized using components shared with each part provided in the vehicle, and various aspects. Is included. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also realized as a program for controlling the multi-view display control device and a recording medium for recording the program. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.

Next, the first display control unit 21b displays the first screen (step S105). Specifically, route guidance for the driver 50 is displayed on the screen on the driver's seat side of the multi-view display unit 41 based on the route guidance information. Next, the information sorting unit 21c sorts the second information from the first information (route guidance information) (step S110). Specifically, information for guiding the passenger 51 is selected from the above-described route guidance information. Finally, the second display control unit 21d displays the selected information on the second screen (step S115). Specifically, guidance for the passenger 51 is displayed on the screen on the rear seat side of the multi-view display unit 41. This step of the multi-view display control process is repeatedly executed partially or entirely in accordance with an instruction from the navigation processing unit during route guidance. The timing for updating the display on the driver's side screen and the rear seat's screen is not particularly limited, and may be performed independently and asynchronously. May be.

Next, a specific example of guidance displayed on the driver seat screen and the rear seat screen by executing the multi-view display control process will be described with reference to FIGS. 4 and 5.
FIG. 4 is a diagram illustrating an example of guidance displayed on the driver seat screen and the rear seat screen when the vehicle is traveling on the expressway. The screen 70 is displayed on the screen on the driver's seat side, and shows a screen that the navigation device 10 displays by default during route guidance on the expressway. The screens 71, 72, 73, and 74 are displayed on the screen on the rear seat side, and the screens 71, 72, and 73 are switched and displayed every predetermined time.

  Screen component elements of the screen 70 include a vehicle position icon 70a, a line 70b indicating a highway, character information 70c, 70d, 70e indicating a distance to a point or facility and an estimated passage time. These three pieces of character information indicate that three of the SA, IC, and JCT existing ahead of the vehicle position are close to the vehicle position. They are 70e, 70d, and 70c in the order of closeness. The first display control unit 21b displays the screen 70 based on the route guidance information acquired by the information acquisition unit 21a.

  The screen 71 is obtained by extracting and enlarging information on the left half of the screen 70. A passenger in the rear seat who is a non-driver may want to know the route guidance information while the vehicle is traveling, but often does not necessarily need the route guidance information with the level of detail required by the driver. Further, since it is far from the display surface than the driver's seat, if a lot of information is displayed at a time and each piece of information is small and small, it is difficult to see from the rear seat. Like the examples of the screen 70 and the screen 71, by extracting a part of the information displayed on the screen for the driver and displaying it on the screen for the passenger in the rear seat, the information for the driver Compared with the case where a lot of information having the same level of detail is displayed on the screen at a time, it is easier for the passengers in the rear seat to recognize the display content on the screen.

  The own vehicle position icon 71a is larger than the own vehicle position icon 70a, and the line 71b indicating the expressway is displayed thicker than the line 70b. Since the line is thick, it is easy to recognize the contents of the information composed of the line. The information sorting unit 21c sorts a part of the information displayed on the driver's seat screen among the route guidance information as information for the passenger 51, and the second display control unit 21d compares the screen information with the screen 70a. Is enlarged and the components corresponding to the same information are enlarged and displayed, so that the screen 71 is displayed on the screen on the rear seat side. The screen components that are displayed based on the same information are larger on the rear seat screen than on the driver seat screen. However, the information that the driver can know can be recognized at a glance.

  The screen 72 displays a part (right half) of the screen 70 and information that is not displayed on the screen 70. On the screen 72, character information 72b indicating the distance to the SA existing ahead of the host vehicle position and the estimated passage time, and character information 72a indicating the distance to the exit IC where the host vehicle is scheduled to get off the general road and the passage time are displayed. Including. The screen 72 has the same guidance format as that of the right half of the screen 70, but is different from the right half of the screen 70 in points and facilities corresponding to the character information. The same information as the character information 72 a is not included in the right half of the screen 70. Further, the icon 72c indicating the equipment included in the facility corresponding to the character information 72b is not included in the right half of the screen 70. Further, the same information as the character information 70c and the character information 70e is not included in the screen 72. Further, the characters on the screen 72 are larger than the characters on the right half of the screen 70. Since the characters are large, it is easy to recognize the contents represented by the characters. The information selection unit 21c selects a part of the route guidance information displayed on the driver's seat screen as information for the passenger 51, and is displayed on the driver's seat screen of the route guidance information. The second display control unit 21d displays the enlarged characters compared to the screen 70a so that the screen 72 is displayed on the screen on the rear seat side.

  In this way, except for information that is not useful for passengers who are non-drivers, such as the distance and time to the IC and JCT that only the host vehicle passes through, it is possible to get off from the vehicle and get to the SA where it can rest Information that is highly useful to the passenger 51, such as how long it takes, what kind of equipment is in the SA, and how much distance to get off the general road, etc., can be easily seen at a glance. .

  The screen 73 includes character information indicating the current time, travel speed, distance to the destination, and estimated arrival time. The characters on the screen 73 are larger than the characters on the right half of the screen 70. The information sorting unit 21c sorts information that is not displayed on the driver's seat screen among the route guidance information as information for the passenger 51, and the second display control unit 21d enlarges the characters compared to the screen 70a. The screen 73 is displayed on the screen on the rear seat side.

  The second display control unit 21d classifies the information selected from the route guidance information into three groups, and displays the screens 71, 72, and 73 by switching and displaying every predetermined period (for example, every 30 seconds). It can be displayed in order. As a result, even if the second information is not displayed at a time on the screen on the rear seat side in order to guarantee the easy viewing for the passenger 51 in the rear seat, the rear seat Information that is highly useful for the passenger 51 can be guided without shortage. Note that, as shown on the screen 74, for example, character information indicating that the IC is currently passing may be scrolled and displayed, such as the character information 74a, each time the IC passes. Further, for example, before passing the IC or SA (for example, 5 minutes before), the character information indicating that it will soon pass may be similarly scrolled and displayed.

  FIG. 5 is a diagram illustrating an example of guidance displayed on the driver seat screen and the rear seat screen when the vehicle is traveling on a general road. The screen 80 is displayed on the screen on the driver's seat side, and shows a screen that the navigation device 10 displays by default during route guidance on a general road. The screens 81, 82, and 83 are displayed on the screen on the rear seat side, and the screens 81, 82, and 83 are switched and displayed every predetermined time. A description of the same processing contents for displaying the screen during traveling on the expressway shown in FIG. 4 will be omitted.

The screen 80 includes a vehicle position icon 80a, a magnetic compass icon 80b, place name character information 80c, facility name character information 80d, a figure 80e indicating an expected arrival time, a line 80f indicating a route, and the like. A map around the car position is displayed.
The screen 81 is an enlargement of the map around the vehicle position on the screen 80. Screen components corresponding to the same information are larger on the screen 81 than on the screen 80. That is, the own vehicle position icon 81a and the compass needle icon 81b are larger than 80a and 80b, respectively. The place name character information 81c is also displayed larger than 80c. A line 81f indicating a road is also displayed thicker than 80f. Further, the screen 81 does not display the graphic 80e indicating the estimated arrival time, and the amount of information is smaller than that of the screen 80. When the amount of information is small, it is easy for the passenger 51 far from the display surface to grasp the information displayed on the screen at a glance.

  Information including at least information that is not displayed on the screen 80 is displayed on the screen 82. The screen 82 includes a host vehicle position icon 82a, a magnetic compass icon 82b, a departure point icon 82c, a destination point icon 82d, and a line 82e indicating a route. A map of a wide area is displayed that includes (that is, includes the entire searched route on one screen). A map near the departure point or the destination point is not displayed on the screen 80. Line 82e is thicker than line 80f. The own vehicle position icon 82a and the azimuth needle icon 82b are larger than 80a and 80b, respectively. The passenger 82 in the rear seat can intuitively grasp the ratio of the remaining route (route from the current location to the destination location) with respect to the entire route from the departure location to the destination location through the screen 82. The information selection unit 21c provides information on the vicinity of the departure point and the destination point that are not displayed on the screen 80 in the route guidance information and the vicinity of the vehicle position displayed on the screen 80 to the passenger 51 in the rear seat. The second display control unit 21d displays the screen 82 by causing the second display control unit 21d to display large components and thick lines. Among the route guidance information, even if the information is not directly displayed on the driver's screen at that time, information including at least the information may be information useful for the passenger 51 in the rear seat. It is kind to the passenger 51.

The screen 83 includes character information indicating the current time, travel speed, distance to the destination, and estimated arrival time, as with the screen 73. The characters on the screen 83 are larger than the characters on the screen 80.
The second display control unit 21d classifies the information selected from the route guidance information into three groups, and displays the screens 81, 82, and 83 by switching and displaying every predetermined period (for example, every 30 seconds). It can be displayed in order.

  As described above, the passenger 51 in the rear seat can visually recognize the information selected from the route guidance information without moving to the angle range 60 on the driver's seat side. Further, since the information is selected from the route guidance information for the passenger 51 in the rear seat, the multi-view display control device 11 guides information designed in advance with appropriate detail when it is highly useful for the passenger 51. can do. Furthermore, since the screen on the rear seat side is displayed with a higher visibility from a distance than the screen on the driver seat side, the passenger 51 in the rear seat can easily view the content of the screen on the rear seat side. In addition, in order to improve visibility, for example, the screen area used for displaying a specific amount of information on the second screen is a screen used for displaying the specific amount of information on the first screen. What is necessary is just to comprise so that it may become larger than this area.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and acquires the first information to be guided in the first angle range of the multi-view display, and displays it on the first screen based on the first information. As long as the information to be guided in the second angle range different from the first angle range is selected from the first information and displayed on the second screen based on the second information, various other implementations are possible. A form can be adopted.

  For example, the multi-view display means may be limited to the dual view function, or may have four or more angle ranges of viewing angles with respect to the display surface. In the above embodiment, the pattern of the driver seat and the rear seat has been described. However, the present invention may be applied to patterns such as a passenger seat and a rear seat, a rear seat first row and a rear seat second row and the like. . In the case of the first row of the rear seats and the second and subsequent rows, the display panel of the multi-view display device may be suspended from the ceiling of the vehicle ahead of the first row of the rear seats, for example. Moreover, the 1st information described in a claim should just be the information which can be displayed on the screen corresponding to a 1st angle range, and is not limited to route guidance information. For example, the first information may be non-route guidance information such as weather forecasts and news, or the first information may include route guidance information and non-route guidance information. In the former case, the second information is selected from the non-route guidance information, and in the latter case, the second information is selected from one or both of the route guidance information and the non-route guidance information. In the above-described embodiment, an example of two persons having different distances from the display surface 41a in the display device having a triple view function has been described. Assuming that, the third information to be guided on the screen corresponding to the third angle range may be selected from the first information or the second information.

  In the example of FIG. 5, the configuration in which the screen 81 is displayed as a narrower map than the screen 80 and the screen 82 is displayed as a wider map than the screen 80 has been described. However, a map in the same range as the screen 80 has the same size. In the case of display, the amount of information may be reduced by not displaying, for example, narrow roads, detailed place names, and facility names. Further, for example, a kanji having a large number of strokes may be displayed in hiragana or katakana. Kanji characters with a large number of strokes are difficult to see when they are far away, so they can be easily seen from a distance by displaying them in hiragana or katakana with the same number of strokes.

In the example of FIG. 5, for example, besides the screens 81, 82, and 83, for example, a screen that displays a destination point and its surrounding map other than the range of the screen 80 may be added. Even if it is information that is not directly displayed on the driver's screen at that time in the route guidance information, if the information is highly useful for the passenger 51 in the rear seat, the passenger Kind to 51.
Also, the color and display attributes of screen components such as graphics, characters, lines, etc. displayed on the screen on the rear seat side (for example, blinking) may be changed from those on the driver seat side so that they can be easily seen from behind. Good.

The multi-view display control device according to the present invention is not limited to being mounted on a vehicle, and the present invention can be applied to a case where the angle between the user and the display surface is different from the display surface. is there.
The information displayed on the screen corresponding to the first angle range (first screen) by the first display control means is included in the first information and is at least part of the first information. It may be all of the information. Included in the first information is at least a part of the first information, which is information acquired for the user in the first angle range, but it is directly on the first screen. This means that information that is not displayed or information that is not displayed at a certain timing is included.
The second information selected by the information selection means may be included in the first information and at least a part of the first information.
The information displayed on the screen (second screen) corresponding to the second angle range by the second display control means indicates the second information itself, but the information displayed on the second screen at a time is the first information. It is not limited to being all of the second information.
