(Processing-Display control processing)
Next, a display control process executed by the display device 1 configured as described above will be described. FIG. 4 is a flowchart of the display control process (in the following description of each process, step is abbreviated as “S”). This display control process is repeatedly executed at a predetermined cycle after the display device 1 is powered on, for example.

  When the display control process is started, the display setting switching unit 12c determines whether a display setting switching event has occurred (SA1). That is, the display setting switching unit 12c acquires information input to the display device 1 from the lighting control unit 2, the illuminance sensor 4, and the internal clock (not shown), and displays the display setting switching condition table 13c illustrated in FIG. It is determined whether or not an event serving as a trigger for automatically switching display settings has occurred in any of the determination target items. According to the example of FIG. 3, the display setting switching unit 12c determines whether the determination target item “lamp” is in the lighting state (ON or ON) of the vehicle headlamp or the auxiliary lamp based on the information input from the lighting control unit 2. When it is detected that “OFF” has been switched, it is determined that a display setting switching event has occurred. For the item “illuminance” to be determined, it is determined that a display setting switching event has occurred when the illuminance detected by the illuminance sensor 4 changes over 5 lux. For the item “current time” to be determined, it is determined that a display setting switching event has occurred when the current time specified based on information input from the internal clock is the sunset time or sunrise time. . The information specifying the sunset time and sunrise time is recorded in advance in the data recording unit 13 for each day, for example, or acquired via a network (not shown).

  Returning to FIG. 4, while the display setting switching event has not occurred (SA1, No), the display setting switching unit 12c repeats the determination of SA1. On the other hand, when a display setting switching event occurs (SA1, Yes), the switching display condition determination unit 12a determines whether the switching display condition is satisfied (SA2). That is, the switching display condition determination unit 12a acquires information input to the display device 1 from the lighting control unit 2, the illuminance sensor 4, and the internal clock, and determines the determination with reference to the switching display condition table 13b illustrated in FIG. It is determined whether or not the switching display condition is satisfied for each target item. According to the example of FIG. 2, the switching display condition determination unit 12 a detects that the auxiliary lamp of the vehicle is turned on based on the information input from the lighting control unit 2 for the determination target item “lamp”. In such a case, it is determined that the switching display condition is satisfied. For the item “illuminance” to be determined, it is determined that the switching display condition is satisfied when the illuminance detected by the illuminance sensor 4 is not less than 1 lux and less than 5 lux, which is the illuminance range in twilight. In addition, for the determination target item “current time”, the time when the switching display condition determination unit 12a determines whether the switching display condition is satisfied is 30 minutes before and 30 minutes after the sunrise time. When it is included in the time zone or the time zone 30 minutes before and 30 minutes after the sunset time, it is determined that the switching display condition is satisfied. As described above, in the example of FIG. 2, although the display setting is automatically switched to the “night screen” by the display setting switching unit 12c, it is still in a dim state, and the display setting of the “day screen” Is likely to be viewed by the user, the switching display condition determination unit 12a determines that the switching display condition is satisfied.

  Returning to FIG. 4, when the switching display condition is not satisfied, that is, when the switching display condition is not satisfied for any of the determination target items in the switching display condition table 13b illustrated in FIG. 2 (SA2, No), display is performed. The setting switching unit 12c automatically switches the display setting, and the display control unit 12b causes the display 10 to display according to the display setting after the switching (SA3). Specifically, the display setting switching unit 12c identifies the state after the transition due to the occurrence of the display setting switching event for the determination target item in which the display setting switching event has occurred, and corresponds to the identified state after the transition. The display setting is specified with reference to the display setting switching condition table 13c illustrated in FIG. Then, the display setting switching unit 12c automatically switches the display setting of the display 10 to the specified display setting, and the display control unit 12b causes the display 10 to display according to the display setting after the switching.

  According to the example of FIG. 3, the lighting control that the lighting state of the lamp after the transition becomes “head lamp ON” or “auxiliary lamp ON” as a result of switching the lighting state of the head lamp or auxiliary lamp of the vehicle. When the display setting switching unit 12c specifies based on the information input from the unit 2, the display setting switching unit 12c switches the display setting to “night screen”. On the other hand, as a result of switching the lighting state of the headlamp or auxiliary lamp of the vehicle, the information input from the lighting control unit 2 indicates that the lighting state of the lamp after the transition is “headlamp OFF and auxiliary lamp OFF”. When the display setting switching unit 12c identifies based on this, the display setting switching unit 12c switches the display setting to “day screen”. Further, the display setting switching unit 12c determines that the illuminance after the transition is “less than 5 lux” as a result of the illuminance detected by the illuminance sensor 4 changing over 5 lux based on the information input from the illuminance sensor 4. If specified, the display setting switching unit 12c switches the display setting to “night screen”. On the other hand, as a result of the illuminance detected by the illuminance sensor 4 changing over 5 lux, the display setting switching unit 12c determines that the illuminance after the transition is “5 lux or more” based on information input from the illuminance sensor 4. If specified, the display setting switching unit 12c switches the display setting to “day screen”. Information input from the internal clock that the time after transition is "after sunset" as a result of the current time specified based on the information input from the internal clock becoming the sunset time or sunrise time When the display setting switching unit 12c specifies based on the above, the display setting switching unit 12c switches the display setting to “night screen”. On the other hand, based on the information input from the internal clock, the time after the transition is “after sunrise” as a result of the current time specified based on the information input from the internal clock being the sunset time or sunrise time. When the display setting switching unit 12c specifies, the display setting switching unit 12c switches the display setting to “day screen”.

  Returning to FIG. 4, after the processing of SA3, the display setting switching unit 12c returns to SA1 and determines again whether or not a display setting switching event has occurred (SA1).

  On the other hand, when the switching display condition is satisfied in SA2, that is, when the switching display condition is satisfied for any of the determination target items in the switching display condition table 13b illustrated in FIG. 2 (SA2, Yes), display control is performed. The unit 12b determines whether or not the display setting after accepting the display setting switching operation by the user has been stored in the RAM (not shown) of the control unit 12 (SA4).

  As a result, when the display setting after acceptance of the display setting switching operation by the user has been stored in the RAM of the control unit 12 (SA4, Yes), the display control unit 12b displays the display according to the stored display setting. The display 10 is made to perform the switching display on the display 10 (SA5). That is, when the “night screen” has already been stored in the RAM as the display setting after accepting the display setting switching operation by the user, the display according to the display setting of the “night screen” is displayed on the display 10. When the “day screen” has already been stored in the RAM as the display setting after acceptance of the display setting switching operation, the display 10 is caused to display according to the display setting of the “day screen”. Details of the process of storing the display setting in the RAM after receiving the display setting switching operation by the user will be described later.

  Further, the display control unit 12b displays an image representing the screen curl displayed on the display 10 as a switching display, and is different from the current display setting in a portion that appears due to the screen curl. The display 10 is caused to display according to the display setting.

  FIG. 5 is a diagram illustrating the display 10 that performs display according to the display setting of the “night screen”, and FIG. 6 is a diagram illustrating a state in which a switching display is displayed on the display 10 illustrated in FIG. 5. When the switching display condition is satisfied, as illustrated in FIG. 6, the display control unit 12 b causes the display 10 to display an image representing the screen blur at the lower right corner. Further, in the portion appearing due to the blur of the screen (the lower portion of the blur), the display corresponding to the display setting (“day screen” in FIG. 6) different from the current display setting (“night screen” in FIG. 6). On the display 10. That is, in the example of FIG. 6, the portion that appears due to the screen blur is a display that has higher brightness and a brighter color scheme than the other portions that are displayed with the “night screen” display setting.

  Returning to FIG. 4, when the display setting after acceptance of the display setting switching operation by the user is not already stored in the RAM of the control unit 12 (SA4, No), the display setting switching unit 12c automatically switches the display setting and displays it. The control unit 12b causes the display 10 to display according to the display setting after the switching, and causes the display 10 to display the switching display (SA6).

  After the process of SA5 or SA6, the display control unit 12b determines whether or not the touch panel 11 has accepted a display setting switching operation by the user (SA7). Specifically, when the touch panel 11 receives a display setting switching operation at a position corresponding to the switching display displayed on the display 10, the display control unit 12 b receives a display setting switching operation by the user. judge. For example, as shown in FIG. 6, the touch panel 11 is pressed at the position of the image representing the screen blur displayed as the switching display at the lower right corner of the display 10, and the pressed portion further moves in the upper left direction of the screen. In the case (when the user performs flick input on the touch panel 11 from the position of the image representing the screen blur in the upper left direction of the screen), the display control unit 12b accepts the switching operation of the display setting by the user. It is determined that

  Returning to FIG. 4, when the touch panel 11 does not accept a display setting switching operation by the user (SA7, No), the display setting switching unit 12c determines whether a display setting switching event has occurred (SA8). Since the specific contents of this determination are the same as the determination of SA1, description thereof will be omitted.

  As a result, when a display setting switching event occurs (SA8, Yes), the display setting switching unit 12c determines whether or not automatic switching of display settings is necessary (SA9). Specifically, the display setting and the display setting switching event when the display setting switching unit 12c determines that the touch panel 11 has not accepted the switching operation of the display setting by the user in the latest determination of SA7 (SA7, No). When the display setting corresponding to the state after transition due to occurrence of the same is the same, the display setting switching unit 12c determines that the automatic switching of the display setting is unnecessary.

  As a result, when automatic switching of display settings is not required (SA9, Yes), the display control unit 12b deletes the switching display displayed on the display 10 (SA10). Thereafter, the control unit ends the display control process.

  On the other hand, when automatic switching of display settings is not necessary (necessary) (SA9, No), the display setting switching unit 12c automatically switches display settings, and the display control unit 12b responds to the display settings after the switching. The display is performed on the display 10 and the switching display displayed on the display 10 is deleted (SA11). Thereafter, the control unit ends the display control process.

  If the display setting switching event has not occurred in SA8 (SA8, No), the process returns to SA7, and the display control unit 12b determines whether the touch panel 11 has accepted the display setting switching operation by the user (SA7). ). In this way, while repeating the processes of SA7 and SA8, the display control unit 12b determines the shape of the image representing the screen blur from the illuminance near the display 10 detected by the illuminance sensor 4 or the internal clock. You may make it change according to the present time based on the input information. FIG. 7 is a diagram exemplifying a state in which the shape of the image representing the blurring of the screen displayed on the display 10 in FIG. 6 is changed. For example, as shown in FIG. 6, the display 10 detected by the illuminance sensor 4 in a state where an image representing screen blur is displayed on the display 10 that performs display according to the display setting of “night screen”. When the illuminance in the vicinity of is gradually increasing (for example, when the sun's altitude is gradually increasing and the brightness of the ambient light is increasing in the morning hours), the display setting needs to be switched to “daytime screen” Therefore, as the illuminance rises, the shape of the image is changed so as to indicate that the screen is more blurred as shown in FIG. On the other hand, the illuminance in the vicinity of the display 10 detected by the illuminance sensor 4 is gradually increased in a state in which an image representing screen blur is displayed on the display 10 that performs display according to the display setting of the “night screen”. (For example, when the altitude of the sun gradually decreases and the brightness of the ambient light decreases in the evening hours), the need to switch the display setting to “daytime screen” is low Therefore, as the illuminance decreases, the shape of the image is changed so as to indicate that the screen blur is further reduced. Thus, the switching display can be displayed on the display 10 in such a manner that the user can more intuitively understand that the display setting can be switched.

  Returning to FIG. 4, when the touch panel 11 accepts a display setting switching operation by the user (SA7, Yes), the display control unit 12b switches the display setting according to the switching operation, and responds to the display setting after the switching. The display is performed on the display 10, and the switching display is displayed on the display 10 (SA12). Specifically, when the touch panel 11 receives a display setting switching operation by the user, the display control unit 12b switches the display setting of the display 10 to a display setting different from the display setting before the switching operation is received. The display 10 is caused to display according to the display setting after switching, and the switching display is displayed on the display 10. FIG. 8 is a diagram illustrating the display 10 after the touch panel 11 receives a display setting switching operation in the display 10 illustrated in FIG. 6. As shown in FIG. 6, when the touch panel 11 receives a display setting switching operation on the display 10 that performs display according to the display setting of “night screen”, the display control unit 12 b sets the display setting to “day screen”. As shown in FIG. 8, the display 10 is made to display according to the display setting of the “daytime screen”.

  Returning to FIG. 4, after the processing of SA12, the display control unit 12b stores the display setting after the switching of the display setting by the user in the RAM (SA13). That is, when the touch panel 11 receives a display setting switching operation, the display control unit 12b stores the display setting of the “day screen” in the RAM. The stored display setting is erased from the RAM when the switching display condition determining unit 12a determines that the switching display condition is not satisfied in the subsequent determination of SA2. On the other hand, when the touch panel 11 accepts a display setting switching operation, the display control unit 12b stores the display setting of the “night screen” in the RAM.

  After the process of SA13, the display control unit 12b returns to SA7, and determines again whether the touch panel 11 has accepted the display setting switching operation by the user (SA7).

(effect)
As described above, according to the present embodiment, the switching display condition determination unit 12a determines that the switching display condition for causing the display 10 to display the switching display indicating that the display setting can be switched by the user is satisfied. When the determination is made, the display control unit 12b causes the display 10 to display a switching display indicating that the display setting can be switched by the user. Therefore, when the display setting displayed on the display 10 is not desired by the user. In addition, it is possible to easily notify the user that the display setting can be switched. For example, if the display setting is “Night Screen” because the small lamp is turned on, but the surroundings are still bright and the “Day Screen” display setting is considered easier to see for the user, etc. The user can be notified that the display settings can be switched so that

  Further, when the display setting is switched by the display setting switching unit 12c, the switching display condition determining unit 12a determines whether or not the switching display condition is satisfied. Therefore, the switching display condition determining unit 12a is automatically switched by the display setting switching unit 12c. The display setting may be displayed by the display setting switching unit 12c as to whether or not it is necessary to display a switching display indicating that the display setting can be switched by the user. The determination can be made immediately at the time of switching.

  In addition, the switching display condition determination unit 12a is configured so that the auxiliary lamp of the vehicle on which the display device 1 is mounted is turned on, the illuminance near the display 10 is within a predetermined range, or the current time is a predetermined time. If it is included in the band, it is determined that the switching display condition is satisfied. Therefore, although the display setting is automatically switched to the “night screen” by the display setting switching unit 12c, it is still in a dim state. In the case where the display setting of “daytime screen” is more likely to be viewed by the user, the user can be notified that the display setting can be switched so that the screen is easy to view for the user.

  In addition, when the switching display condition determining unit 12a determines that the switching display condition is satisfied, the display control unit 12b displays, as the switching display, an image representing the screen curl displayed on the display 10 as the display. 10 is displayed on the display 10 according to the display setting different from the current display setting in the portion appearing due to the screen curling, so that it is intuitive for the user that the display setting can be switched. The switching display can be displayed on the display 10 in a manner that can be grasped.

  In addition, since the display control unit 12b changes the shape of the image representing the blur of the screen according to the illuminance near the display 10 or the time, it is more intuitive for the user that the display setting can be switched. The switching display can be displayed on the display 10 in a manner that can be grasped.

  Further, when the touch panel 11 receives a display setting switching operation at a position corresponding to the switching display, the display control unit 12b switches the display setting of the display 10, and therefore accepts an intuitive operation for the user as the switching operation. The display setting can be switched based on the operation.

  In addition, when the display setting is switched by the user, the display control unit 12b stores the display setting after receiving the switching operation, and then the switching display condition determination unit 12a satisfies the switching display condition. When the determination is made, the display 10 is displayed on the display 10 according to the stored display setting. Therefore, the user's tendency regarding the selection of the display setting is learned, and the display 10 is displayed with the display setting suitable for the user. It is possible to provide the display device 1 with less operational burden for the user.
