Description

  The present invention relates to a display information generation device and a display information generation method for generating information to be displayed on an in-vehicle display device.

  Conventionally, various ideas have been made to improve the visibility of display information displayed on an in-vehicle display device.

  For example, a technique is disclosed in which video captured by a camera (hereinafter referred to as a video image) is divided into a plurality of regions, and blur processing is performed for each region in accordance with the relative speed between an object included in each region and the host vehicle. (For example, refer to Patent Document 1).

JP 2008-27138 A JP 2007-69766 A

  By the way, in recent years, in display devices such as a meter panel having a function of displaying an image, two or more types of drawing objects are generally displayed as images, for example, taken by a camera which is the first drawing object. There has been proposed a system that displays information of the host vehicle such as a speed, which is a second drawing object, superimposed on a video image, a map image, or the like. In this case, when the traveling speed of the host vehicle is high, the display content of the first drawing object that is the background of the second drawing object changes one after another, and the visibility of information such as the speed of the second drawing object is poor. There is a problem of becoming.

  In Patent Document 1, the drawing object displayed on the display device is only a video image (that is, there is one drawing object), and the driver performs blurring processing on each area obtained by dividing the video image. Facilitates recognition and judgment of objects to be noted. However, since the processing for dividing the video image is performed in real time, there is a problem that the processing load increases. In addition, it is expected that a video image displayed on the display device flickers or color tone mismatches at the boundary portions of each region due to an error in image processing.

  In other words, the technique disclosed in Patent Literature 1 puts a blurring process on a part of the first drawing object in order to improve the visibility of the first drawing object. There is no suggestion of a method for improving the visibility of the other drawing object by blurring a part of the one drawing object. In a display device that displays two or more types of drawing objects, if the technique disclosed in Patent Document 1 is forcibly adopted, the first drawing object is subjected to blurring processing for each divided region. Since the blurring process is performed regardless of the position of the second drawing object, it cannot contribute to the improvement of the visibility of the second drawing object.

  In addition, a technique (for example, see Patent Document 2) that performs gradation processing on the background boundary portion of different drawing objects is disclosed so that the color tone between the backgrounds of a plurality of drawing objects does not change abruptly. The gist of this document is to pursue the design by combining the colors, and has no effect of improving the visibility of the second drawing object.

  Thus, conventionally, it cannot be said that the visibility of necessary information is improved according to the driving situation.

  The present invention has been made to solve these problems, and provides a display information generation device and a display information generation method capable of improving the visibility of necessary information according to driving conditions. Objective.

  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
First, the configuration of the display information generation apparatus according to Embodiment 1 of the present invention will be described.

  FIG. 1 is a block diagram illustrating an example of the configuration of the display information generation device 1.

  The display information generation device 1 is a device that generates information to be displayed on the in-vehicle display unit 11, and includes an overall control unit 2, a drawing object generation unit 3, a drawing object composition unit 4, and a drawing object storage unit 7. A video input unit 8, a vehicle sensor I / F (interface) unit 9, and a communication unit 10.

  The overall control unit 2 controls each component of the display information generation device 1. In particular, control of each component related to the blurring process described later, route guidance processing, and the like are performed.

  Based on the control by the overall control unit 2, the drawing object generation unit 3 performs a blurring target drawing object (first drawing object) that is a target of blurring processing and a non-blurring target drawing object (second processing target) that is not a target of blurring processing. Drawing object).

  The drawing object composition unit 4 includes a blur processing unit 5 and a composition processing unit 6.

  The blur processing unit 5 performs blur processing on the blur target drawing object generated by the drawing object generating unit 3. The blurring degree (blurring degree) of the blurring process performed in the blurring processing unit 5 is controlled by the overall control unit 2 in accordance with a predetermined condition.

  The synthesis processing unit 6 superimposes and synthesizes the blurring target drawing object after the blurring processing by the blurring processing unit 5 and the non-blurring target drawing object generated by the drawing object generation unit 3. Here, the blurring target drawing object is a background image displayed on the display unit 11, and the non-blurring target drawing object is an information image (display unit 11) that presents predetermined information superimposed on the blurring target drawing object. Information that should be displayed on the screen).

  The drawing object storage unit 7 stores information to be displayed on the display unit 11 such as map information, icon images, menu screens, and various meter formats as drawing objects (drawing object data). Here, the map information includes information necessary for map display such as roads and buildings. The icon image includes a bitmap format image (bitmap image) such as an orientation icon and a scale icon as shown in FIG.

  Each drawing object includes a “blur” or “non-blur” attribute. Therefore, a drawing object including the “blur” attribute is a blur object drawing object, and a drawing object including the “non-blur” attribute is a non-blur object drawing object.

  The video input unit 8 inputs a video (video image) taken by the camera 20.

  The camera 20 photographs the vicinity of the host vehicle. For example, a camera that captures the front of the host vehicle or a camera that captures the rear of the host vehicle may be used.

  The vehicle sensor I / F unit 9 includes a GPS (Global Positioning System) 13, a vehicle speed pulse 14, a gyro sensor 15, a vehicle control device 16, an engine control device 17, and body system control via an in-vehicle LAN (Local Area Network) 19. It is connected to the device 18 or the like. The overall control unit 2 can obtain various information via the in-vehicle LAN 19 and the vehicle sensor I / F unit 9.

  Information acquired by each of the GPS 13, the vehicle speed pulse 14, and the gyro sensor 15 is input to the overall control unit 2 via the vehicle sensor I / F unit 9, and the position of the host vehicle is detected by the overall control unit 2. The That is, the overall control unit 2 has a function of detecting the position of the host vehicle.

  The vehicle control device 16 inputs an operation by a driver from a brake pedal, an accelerator pedal, or a steering wheel, and controls traveling of the host vehicle. For example, the speed of the host vehicle is controlled by controlling the number of revolutions of the engine, the brake system, and the like, or the traveling direction of the host vehicle is controlled by controlling the posture of the shaft. It also controls semi-automatic driving functions such as auto cruise.

  The engine control device 17 performs fuel control and ignition timing control.

  The body system control device 18 controls operations not directly related to traveling in the host vehicle. For example, it controls wiper driving, lighting information transmission, blinker lighting, door opening and closing, window opening and closing.

  The communication unit 10 communicates with a communication device existing inside and outside the host vehicle, and can send and receive a phone call or mail. Here, the communication device is only required to be able to make a call or send / receive mail, and may be, for example, a mobile phone, a smartphone, a wireless LAN between roads and vehicles installed near a road, Bluetooth (registered trademark), or the like. .

  The display unit 11 displays the drawing object combined by the drawing object combining unit 4. Here, the display unit 11 may be a monitor of a navigation device, a meter panel provided in an instrument panel unit of a vehicle, or may have a split view function. Note that the split view function refers to a function of displaying images having different display contents depending on the viewing direction on one display unit. For example, different images can be viewed simultaneously from the driver seat and the passenger seat.

  The operation input unit 12 may be anything that inputs a user operation, such as a touch panel or a mechanical switch.

  Next, the operation of the display information generating apparatus 1 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 3, the display unit 11 is assumed to be a meter panel. The meter panel has a travel distance (displayed as 10,000 km in the upper left in the figure) and a tachometer (in the center in the figure, 0, 1, 2,. ······································································· 9, change the numerical value and display color of “•” according to the number of revolutions)

  FIG. 2 is a flowchart showing an example of the operation of the display information generating apparatus 1.

  In step S <b> 21, the drawing object generation unit 3 acquires vehicle information including speed information of the host vehicle, engine rotation information, and travel distance information from the vehicle control device 16 via the vehicle sensor I / F unit 9. In addition, the drawing object generation unit 3 acquires a drawing object having a travel distance, tachometer, and speedometer format (drawing object) from the drawing object storage unit 7.

  Next, the overall control unit 2 determines whether the drawing object is “blurred” or “non-blurred” based on the attribute included in the drawing object acquired by the drawing object generation unit 3 from the drawing object storage unit 7. The determination result is input to the drawing object generation unit 3. The drawing object generation unit 3 generates either a blurring target drawing object or a non-blurring target drawing object based on the attribute determination result input from the overall control unit 2. Here, the drawing object generation unit 3 generates a non-blurring target drawing object based on the vehicle information acquired via the vehicle sensor I / F unit 9 and the drawing object acquired from the drawing object storage unit 7.

  In step S <b> 22, the overall control unit 2 assumes that the video image input to the video input unit 8 includes a “blur” attribute, and inputs a determination result of the attribute to the drawing object generation unit 3. That is, in the first embodiment, the attribute of the video image is “blur”. The drawing object generation unit 3 generates a video (video image) captured by the camera 20 acquired from the video input unit 8 as a blurring target drawing object.

  In step S <b> 23, the overall control unit 2 acquires speed information of the host vehicle based on the vehicle speed pulse 14 via the vehicle sensor I / F unit 9.

  In step S24, the overall control unit 2 determines a conditional branch based on the speed V of the host vehicle acquired in step S23. As a result of the determination, when the speed V is less than 10 km / h (V <10 km / h), the process proceeds to step S25, where the speed V is 10 km / h or more and less than 40 km / h (10 km / h ≦ V <40 km / h). If the speed V is 40 km / h or more (V ≧ 40 km / h), the process proceeds to step S27.

  In step S25, the overall control unit 2 determines that the blur level = 0. Here, the blurring degree = 0 indicates that the blurring process is not performed.

  In step S26, the overall control unit 2 determines that the blurring degree = 1. Here, the blurring degree = 1 indicates that the blurring degree is weaker than the blurring degree = 2.

  In step S27, the overall control unit 2 determines that the blurring degree = 2. Here, the blur level = 2 indicates that the blur level is higher than that of the blur level = 1.

  In step S <b> 28, the overall control unit 2 inputs the blur degree information determined in any one of step S <b> 25, step S <b> 26, or step S <b> 27 to the blur processing unit 5.

  Next, the blurring processing unit 5 performs blurring processing on the blurring target drawing object generated by the drawing object generating unit 3 based on the blur degree information input from the overall control unit 2. At this time, the blurring processing unit 5 performs a blurring process on the entire blurring target drawing object.

  In step S29, the synthesis processing unit 6 synthesizes the blurring target drawing object and the non-blurring target drawing object that have been subjected to the blurring process by the blurring processing unit 5, and displays the synthesized drawing object as a display image signal as a display image signal. 11 is output.

  FIG. 3 is a diagram illustrating an example of display on the display unit 11.

  FIG. 3A shows an example of display when the speed of the host vehicle is low (V <10 km / h). For example, in FIG. 3A, the speed V = 0 km / h. In this case, the blurring degree = 0, and the blurring process is not performed on the video image that is the blurring target drawing object.

  FIG. 3B shows an example of display when the speed of the host vehicle is medium speed (10 km / h ≦ V <40 km / h). For example, in FIG. 3B, the speed V = 32 km / h. In this case, the blurring degree = 1, and a weak blurring process is performed on the video image that is the blurring target drawing object. After the blurring process, the video image is slightly blurred.

  FIG.3 (c) has shown an example of the display in case the own vehicle is high speed (V> = 40km / h). For example, in FIG. 3C, the speed V = 62 km / h. In this case, the blurring degree = 2, and the blurring process stronger than that in FIG. 3B is performed on the video image that is the blurring target drawing object. After the blur processing, the content of the video image cannot be determined.

  From the above, according to the first embodiment, the blurring target drawing object and the non-blurring target drawing object are generated and the blurring process according to the speed of the host vehicle is performed on the non-blurring target drawing object.

Further, for example, information on the other party's telephone number and name in the telop display of FIG. 11B is acquired from the other party's communication device via the communication unit 10. The drawing object generation unit 3 generates a telop based on the telop format and the other party's telephone number information.

  In step S106, the overall control unit 2 determines that the blurring degree = 1. Here, the blurring degree = 1 indicates that the blurring process is performed.

  In step S107, the overall control unit 2 inputs the blur degree information determined in step S104 or step S106 to the blur processing unit 5.

  Next, the blurring processing unit 5 performs blurring processing on the blurring target drawing object generated by the drawing object generating unit 3 based on the blur degree information input from the overall control unit 2. At this time, the blurring processing unit 5 performs a blurring process on the entire blurring target drawing object.

  In step S108, the composition processing unit 6 synthesizes the blurring target drawing object and the non-blurring target drawing object that have been subjected to the blurring process by the blurring processing unit 5, and displays the synthesized drawing object as a display image signal as a display image signal. 11 is output.

  FIG. 11 is a diagram illustrating an example of display on the display unit 11.

  FIG. 11A shows an example of a display when there is no incoming call. In this case, the blurring degree = 0, and the blurring process is not performed on the blurring target drawing object.

  FIG. 11B shows an example of a display when a phone call is received. In this case, the blurring degree = 1, and blurring processing is performed on the blurring target drawing object. At this time, weak blur processing may be performed on the blur target drawing object, or strong blur processing may be performed.

  From the above, according to the sixth embodiment, when displaying information on alerting the driver as a telop on the display unit 11, the blurring process is performed on the drawing object to be blurred. Can be improved. Note that the same effect can be obtained even when a mail is received instead of when a call is received.

An object), (b) a blurring process on the blurring target drawing object generated in the step (a), and a blurring target rendering object after the blurring process, and a process A step of combining the non-blurring target drawing object generated in (a), and (c) a step of controlling the degree of blurring of the blurring processing performed in step (b) according to a predetermined condition. With.

  As described above, the same effects as those in the above-described embodiment can be obtained by operating the software for executing the operation in the above-described embodiment in a portable communication terminal, a PND, or a server.

  In FIG. 1, each of the display information generation apparatus 1 (the overall control unit 2, the drawing object generation unit 3, the drawing object synthesis unit 4, the blurring processing unit 5, and the synthesis processing unit 6) uses a CPU based on software. This is realized by executing program processing. Further, if possible, each of the display information generation devices 1 (the overall control unit 2, the drawing object generation unit 3, the drawing object synthesis unit 4, the blurring processing unit 5, and the synthesis processing unit 6) is replaced with hardware (for example, electric An arithmetic / processing circuit or the like configured to perform a specific operation or process on the signal may be used. Further, both of the above may be mixed.

  In FIG. 1, the drawing object storage unit 7 may have a function of holding data, for example, an HDD (Hard Disk Drive), a DVD (Digital Versatile Disk), a semiconductor memory, or the like.

  In FIG. 1, the camera 20 may be a nose view camera or a night view camera (infrared camera).

  In FIG. 1, the drawing object storage unit 7 has a function of acquiring drawing object data from the outside via the communication unit 10, and may acquire drawing object data necessary from the outside when necessary. .

  2, 4, 6, and 10, the process may be started when the engine is started and the process may be repeated until the engine is turned off (the process ends). Here, starting the engine means that the engine starts to rotate, and that the engine is turned off means that the engine stops rotating.

  2, 4, 6, and 10, when a mechanical switch of the operation input unit 12 is pressed, a program for executing a blurring process (a process in each step) is started. When a switch (which may be the same as the switch for starting the blurring process) is pressed, the program for executing the blurring process may be terminated. At this time, the blurring process is repeated until the switch for ending the blurring process is pressed.

  2 and 4, the threshold value of the speed V of the host vehicle for determining the blurring degree is not limited to 10 km / h and 40 km / h, and may be any value.

However, the overall control unit 2 increases the blurring degree according to the speed of the host vehicle. You may make it perform the control changed in steps or continuously. Even in such a case, the same effect as in the first and second embodiments can be obtained.

  In the first to eighth embodiments, the blurring process for the blurring target drawing object includes a blur process, a translucent process, and a gradation process. For example, in the blur process, the blur process is uniformly performed on the entire area where the blur process is performed. The semi-transparent process is a process for changing the transparency of the entire area to be blurred. In the gradation process, an arbitrary gradation process is performed on the area to be blurred. By performing each of these processes, the same effect as in the first to eighth embodiments can be obtained.

  In the first to eighth embodiments, the non-blurring target drawing object may be changed to a color scheme having good visibility according to the background color (color scheme of the blurring target drawing object). At this time, when there are a plurality of non-blurring target drawing objects, the color scheme may be changed for each non-blurring target drawing object. For example, if the background color is dark, the non-blurring target drawing object color scheme is a light color, and if the background color is light, the blur target drawing object color scheme is a dark color. The color scheme of the object may have a complementary color relationship. In the fourth embodiment, the lighting color of the warning lamp 21 and the color arrangement of the blurring drawing object may have a complementary relationship.

  In FIG. 6, the distance X for determining the blurring degree is not limited to 10 m and 50 m, and may be any value.

  In the third embodiment, the overall control unit 2 performs control to change the blurring degree from 0 to 2 according to the distance between the current position of the host vehicle and the guide point. Control for changing the blurring degree in multiple steps or continuously may be performed according to the distance between the two. Even in such a case, the same effect as in the third embodiment can be obtained.

  In the third embodiment, the case where the guidance screen is displayed when the own vehicle approaches the guidance point has been described. For example, when the own vehicle approaches an intersection, lane information (left turn lane, straight lane, right turn lane, etc.) is displayed. The present invention is applicable even when a guidance icon such as a lane guidance is displayed.

  In the third embodiment, it has been described that the blur processing is performed on the non-blurring target drawing object (including the building) in the map image when the host vehicle approaches the guidance point. Of these, the blurring process may not be performed only on buildings near the guidance point. That is, the blurring drawing object (first drawing object) includes a plurality of drawing objects (third drawing object), and the blurring process 5 blurs each of the plurality of drawing objects (third drawing object). You may make it perform a blurring process so that a degree may differ. In this way, the driver can easily recognize a building that is a landmark near the guidance point.

  In the fourth embodiment, the case where a map image as shown in FIG. 5 is displayed on the display unit 11 has been described, but a meter as shown in FIG. 3 may be displayed on the display unit 11 (that is, the display unit 11). May be a meter panel). In this case, the blurring process is the same as in the first embodiment.

  In the fourth embodiment, it has been described that the blurring process is ended after a predetermined time has elapsed in the display state shown in FIG. 8B. However, the blurring process may be repeatedly performed at regular time intervals.

  In the fourth embodiment, when the warning lamp 21 is turned on, gradation processing may be performed on the blurring target drawing object displayed on the display unit 11. At this time, gradation processing is performed such that the blur nearer to the warning lamp 21 in the blur target object is strengthened (blur degree is increased), and the blur is weakened (decrease the blur degree is smaller) as the distance from the warning lamp 21 increases. Also good. Even in this case, the same effect as in the fourth embodiment can be obtained.

  In the fifth embodiment, the blur process is performed with a blur degree different from that of the overlapped area on the other areas other than the area of the blur target draw object superimposed on the non-blur target draw object. Also good. That is, the overall control unit 2 performs control so that the degree of blur is different between a region where the non-blurring target drawing object and the blurring target drawing object are superimposed and a region other than the superimposed region. It may be. For example, gradation processing may be performed in which blurring of the superimposed area is strengthened (blurring degree is increased) and blurring is weakened (blurning degree is decreased) as the distance from the overlapping area is increased. Further, as for the area other than the overlapping area, the blur may be increased as the speed of the host vehicle increases. Even in this case, the same effect as in the fifth embodiment can be obtained.

  In the fifth embodiment, the blurring process may change the blurring degree according to the speed of the own vehicle as in the first embodiment, or may be a constant blurring degree regardless of the speed of the own vehicle.

  In the sixth embodiment, the case of receiving a call or e-mail has been described as an alert to the driver. However, various information acquired via the communication unit 10 such as when receiving emergency information may be used.

  In the seventh embodiment, for example, the screen viewed from the driver's seat side can perform blurring processing according to various conditions as described in the first to fifth embodiments.

  In FIG. 14B, the blurring process may be performed only on the area of the blurring drawing object to be superimposed on the telop. Or the display similar to FIG.13 (b) may be sufficient.

  When a HUD (Head Up Display) and a meter panel are provided in the host vehicle, the blurring process as in the first, fourth, and fifth embodiments may be performed on the meter panel. In addition to the HUD and meter panel, when a display unit such as a navigation device is provided, the display unit may be subjected to blurring processing as in the second, third, fourth, and sixth embodiments. Good.

  In the seventh embodiment, the present invention can also be applied to a case where a text message is transmitted to a driver from a communication device (for example, a mobile phone) owned by a person seated in a rear seat in the own vehicle. Specifically, the text message sent to the driver is displayed as a telop and the blurring process is performed on the blurring target drawing object (see, for example, FIG. 11B).

  You may make it change the blurring degree of the blurring object drawing object according to the scroll speed at the time of scrolling the map image displayed on the display part 11. FIG. Specifically, as the scroll speed increases, the blurring of the drawing object to be blurred may be increased.

  When the map image displayed on the display unit 11 is heading up, the map image may frequently rotate when the vehicle travels on a mountain road or a road with many curves. In such a case, the blurring degree of the blurring drawing object may be changed according to the rotation speed of the map image. Specifically, the blurring of the blurring target drawing object may be strengthened as the rotation speed increases.

  In Embodiments 1 to 8, the blurring target drawing object may be a blurring target drawing object when the operation restriction is applied. Here, the screen on which the operation is restricted refers to a screen that must be stopped and operated, such as a destination setting screen.
