  The first VRAM 331 receives the video signal from the selection unit 330, synthesizes it as a video that can be displayed on one screen of the LCD 340, and outputs it to the synthesis unit 333 connected in the subsequent stage. This synthesized image is, for example, an image displayed on the driver's seat side.

  Similarly to the first VRAM 331, the second VRAM 332 also receives the video signal from the selection unit 330, synthesizes it as a video that can be displayed on one screen, and outputs it to the synthesis unit 333 connected to the subsequent stage. The synthesized video is, for example, a video displayed on the passenger seat side.

  The combining unit 333 is also connected to the LCD 340. The synthesizer 333 synthesizes the video signal from the first VRAM 331 and the video signal from the second VARM 332 so as to be alternately arranged in pixel units (or in units of a plurality of pixels). The synthesized video signal is output to the LCD 340. Note that the combining unit 333 is actually a memory such as a VRAM.

  The LCD 340 displays a video based on the video signal from the synthesis unit 333. Note that a parallax barrier 108 having slits in pixel units (or in units of a plurality of pixels) is provided on the front surface of the LCD 340 on the light emission direction side. The images rearranged alternately can be viewed from different viewpoints by the parallax barrier 108. Therefore, for example, a navigation map image can be viewed on the driver seat side, and a TV image can be viewed simultaneously on the passenger seat side.

  The overall control microcomputer 360 controls the entire display device 300. An operation unit 370 and an occupant detection sensor 380 are connected to the overall control microcomputer 360.

  The operation unit 370 is an interface between the user and the display device 300. The operation unit 370 may be a touch panel operation button (such as the touch panel 124 of FIG. 6) displayed on the LCD 340 screen, or may be a group of buttons arranged in the vicinity of the LCD 340.

  The occupant detection sensor 380 is a sensor that detects an occupant who gets in the driver's seat. For example, a seat sensor that detects whether or not an occupant is seated on a seat, a sensor that detects opening and closing of a door on the driver's seat side, a sensor that detects wearing of a seat belt, and the like. The occupant detection sensor 380 may also detect a passenger on the passenger seat side.

  The display device 300 configured as described above can display information in a distributed manner. FIG. 11 is a display example. A map image 345 for navigation is displayed on both the driver's seat and the passenger seat side, and the first page 346 of the facility list is displayed on the driver's seat side, and the second page 347 of the facility list is distributed on the passenger seat side. Is displayed. The first display information described above is the facility list 346 on the driver's seat side, and the second display information is the facility list 347 on the passenger seat side. An example of the operation of the display device 300 will be described using this example.

  First, the microcomputer 310 outputs a video signal for displaying the facility list 346 to the first output unit 311. Further, the microcomputer 310 outputs a video signal for displaying the facility list 347 to the second output unit 312.

  In the first output unit 311 and the second output unit 312, the information in each facility list 346 and 347 is changed to have the size shown in FIGS. 11A and 11B, and the video signal is selected by the selection unit 330. Output to.

  On the other hand, the navigation RGB video signal output unit 320 outputs a video signal for displaying the navigation map image 345 to the third and fourth output units 321 and 322. The third and fourth output units 321 and 322 also change and output the RGB video signal so that the navigation video has the size shown in FIG.

  The selection unit 330 displays a video signal for displaying the facility list 346 from the first output unit 311 and a map image 345 from the third output unit 321 based on a control signal from the overall control microcomputer 360. RGB RGB video signals are selected and output to the first VRAM 331.

  In the first VRAM 331, a combined video signal is generated so that the facility list 346 and the navigation map image 345 can be displayed on one screen of the LCD 340. In the first embodiment, an image displayed on the driver's seat side is stored in the first VRAM 331.

  Similarly, the selection unit 330 selects the video signal for displaying the facility list 347 from the second output unit 312 and the RGB video signal for displaying the map image 345 from the fourth output unit 322. Output to the second VRAM 332.

  In the second VRAM 332, a combined video signal is generated so that the facility list 347 and the navigation map image 345 are displayed on one screen. In the first embodiment, an image displayed on the passenger seat side is stored in the second VRAM 332.

  In the synthesizing unit 333, the video signal on the driver seat side (video signal from the first VRAM 331) and the video signal on the passenger seat side (video signal from the second VRAM 332) are alternately rearranged in units of pixels.

  When the rearranged video signals are output to the LCD 340, the driver's seat side occupant can see the navigation map 345 and the facility list 346 through the parallax barrier 108 (FIG. 11A). The passenger on the passenger seat side can see the same navigation map 345 and facility list 347 (FIG. 11B).

  As in this example, by displaying the facility lists 346 and 347 separately on the driver's seat side and the passenger seat side, it is possible to increase the amount of information that can be displayed at one time without switching the screen. In addition, the size of each character in the facility lists 346 and 347 can be displayed in a two-screen display size, so that the screen is easy to see, and the entire screen is easy to see without reducing the navigation video. Become.

  After the facility lists 346 and 347 are displayed in a distributed manner, the facility to be visited can be selected by joint work between the driver side passenger and the passenger side passenger. The selection is performed, for example, by selecting a list on the screen by an operation by the operation unit 370. The selected facility may be displayed as a marker on the map image 345 for navigation. Furthermore, destination setting registration by navigation may be performed by this selection.

  As the information displayed in the first embodiment, the facility list has been described as an example. Of course, in addition to this, various information such as traffic information such as traffic jam information, menu information about operation menus, information about destinations, information about service areas, information about service stations, information about service centers, information about restaurants, etc. are distributed. Can also be displayed. For example, this can be realized by the microcomputer 310 outputting the video signal of the first page of each information to the first output unit 311 and the video signal of the second page to the second output unit 312. Even in this case, the same effect as the above-described example is achieved.

  Further, the information displayed on the driver's seat side and the passenger seat side may be displayed with different colors. For example, it is conceivable to change the color of characters in the facility list or change the color of the displayed background. For example, it can be realized by storing information of different colors in the microcomputer 310.

  Furthermore, although the example in which the same map image 345 is displayed on the driver's seat side and the passenger seat side has been described, for example, the facility images 346 and 347 are displayed on the driver's seat side on the entire screen without the map image 345 being displayed. And on the passenger seat side. In this case, the overall control microcomputer 360 controls not to output the video signal from the RGB video output unit 320, and the first and second output units 311 and 312 directly change the input video signal without change. It can be realized in the same manner as in the above-described example.

  Furthermore, in the first embodiment, the facility list 346 on the first page and the facility list 347 on the second page are displayed at two viewpoint positions on the driver's seat side and the passenger seat side, respectively. In addition, information such as each facility list can be distributed and displayed at three or more viewpoint positions. For example, a fifth output unit is provided between the microcomputer 310 and the selection unit 330, and a third VRAM is provided between the selection unit 330 and the synthesis unit 333, and these are used for the third viewpoint position. If the video signal is input / output, it is possible to display each information distributed at the three viewpoint positions.

  Further, the facility list 346 displayed on the driver seat side may be displayed on the passenger seat side, and the facility list 347 displayed on the passenger seat side may be displayed on the driver seat side. For example, the overall control microcomputer 360 controls the selection unit 330 based on the operation of the operation unit 370, and the video signal from the second output unit 312 and the video signal from the third output unit 321 are the first. This can be realized by outputting to the VRAM 331 and outputting the video signal from the first output unit 311 and the video signal from the fourth output unit 322 to the second VRAM 332. Alternatively, by rearranging the pixels in the combining unit 333, the pixels displayed on the driver's seat side are converted into video signals output from the second VRAM 332, and the pixels displayed on the passenger seat side are switched from the first VRAM 331. It can also be realized by arranging to allocate to the output video signal.

[Example 2]
Next, Example 2 will be described. The second embodiment is an example in which the facility list is displayed in a distributed manner, but the display form is changed between the driver's seat side and the passenger seat. Specifically, a facility list of an upper hierarchy is displayed on the driver's seat side, and a facility list including a lower hierarchy is displayed on the passenger seat side.

  FIG. 12 is an example of a display screen in the second embodiment. The entire list related to the facility is displayed on the driver's seat side, and specific items of the list are displayed on the passenger seat side.

  The overall configuration of the display device 300 of the second embodiment is exactly the same as that of the first embodiment. The operation will be described with reference to FIG.

  The microcomputer 310 outputs a video signal for displaying a higher-tier facility list 348 (first display information) displayed on the driver's seat side to the first output unit 311. In addition, the microcomputer 310 outputs a video signal for displaying a lower-layer facility list 349 (second display information) displayed on the passenger seat side to the second output unit 312.

  The first and second output units 311 and 312 change the input video signals so that they can be displayed on a part of one screen of the LCD 340, and output the video signals to the selection unit 330, respectively.

  On the other hand, the RGB video signal output unit 320 outputs the navigation RGB video signal to the third and fourth output units 321 and 322 as in the first embodiment.

  The third and fourth output units 321 and 322 also output RGB video signals that can be displayed on a part of one screen of the LCD 340 to the selection unit 330, respectively.

  The selection unit 330 selects the video signal from the first output unit 311 and the navigation RGB video signal from the third output unit 321 based on the selection control signal from the overall control microcomputer 360. The data is output to the first VRAM 331. In the first VARM 331, an image in which a navigation map image 345 and a higher-layer facility list 348 are displayed is generated.

  Further, the selection unit 330 selects the video signal from the second output unit 312 and the navigation RGB video signal from the fourth output unit 322 based on the control signal from the overall control microcomputer 360, and 2 to the VRAM 332. The second VRAM 332 generates an image in which a navigation map 345 and a lower-layer facility list 349 are displayed.

  The synthesizing unit 333 synthesizes the video signal from the first VRAM 331 and the video signal from the second VRAM 332 by alternately rearranging them in units of pixels. Therefore, the parallax barrier 108 of the LCD 340 displays the image shown in FIG. 12A on the driver seat side and the image shown in FIG. 12B on the passenger seat side.

  In this way, the facility list display form is changed, and the upper-tier facility lists 348 and 349 are displayed on the driver's seat side and the lower-tier facility list side, so that the screen switching operation is performed as in the first embodiment. It is possible to display a large number of facility list information at a time without performing the operation. In addition, the characters of the facility lists 348 and 349 and the navigation video are not easily reduced, and the display is very easy to see.

  After such a display is made, the facility list can be selected by joint work between the driver's side passenger and the passenger's side passenger. The selection is performed by the operation unit 370.

  In the second embodiment, as in the first embodiment, it is also possible to display information such as a facility list having different display forms from three or more viewpoint positions. For example, the information of each layer can be viewed from each viewpoint position by being distributed for each layer such as an upper layer, a middle layer, and a lower layer.

  Further, the other examples described in the first embodiment can also be applied in the second embodiment and have the same effects.

[Example 3]
Next, Example 3 will be described. As in the first embodiment, information is displayed in a distributed manner on the driver seat side and the passenger seat side. In the third embodiment, the display form of the audio screen is changed between the driver seat side and the passenger seat side.

  FIG. 13 is a configuration example of the display device 300 according to the third embodiment. The same components as those in FIG. 1 are denoted by the same reference numerals. The difference is that the present display device 300 includes a first microcomputer 315 and a second microcomputer 325. The first microcomputer 315 outputs a video signal for displaying a title display and a reproduction time display, and the second microcomputer 325 outputs a video signal for displaying an equalizer display.

  The second microcomputer 325 is connected to a generation unit 324 for generating an equalizer display video signal. The generation unit 324 generates a video signal for performing equalizer display based on a reproduction signal from a recording medium such as a CD, MD, or HD. The second microcomputer 325 outputs the signal generated by the generation unit 324 to the third output unit 321 and the fourth output unit 322.

  Here, the correspondence relationship with the display device of FIG. 6 will be described. The first microcomputer 315 and the first and second output units 311 and 312 are provided in the CD / MD playback unit 201 or the HD playback unit 205. The second microcomputer 325 and the third and fourth output units 321 and 322 are provided in the CD / MD playback unit 201. In FIG. 6, there is only one output signal line from the CD / MD playback unit 201 or the like to the distribution circuit 207, but this is for convenience of explanation. In the second embodiment, there are a plurality of output lines such as two or four. Output signal lines are connected to the distribution circuit 207. The correspondence relationship of FIG. 6 with another configuration in the display device 300 is the same as that in the first embodiment.

  FIG. 14 is an example of a display screen in the third embodiment. FIG. 14A shows a display screen example on the driver's seat side, where a title display 351 and a reproduction time display 352 are displayed. FIG. 14B is an example of a display screen on the passenger seat side, and an equalizer display 353 is displayed together with these displays 351 and 352. The overall operation will be described with reference to the screen example shown in FIG.

  First, the first microcomputer 315 outputs to the first output unit 311 and the second output unit 312 a video signal that displays the title and playback time of the audio being played back. The first output unit 311 outputs the input video signal as it is, and the second output unit 312 outputs the input video signal so that it can be displayed on a part of one screen of the LCD 340.

  On the other hand, the second microcomputer 325 outputs a video signal for displaying the equalizer display 353 to the third and fourth output units 321 and 322. In addition, the third and fourth output units 321 and 322 change and output the video signal so that the display size is similarly changed.

  The selection unit 330 outputs the video signal from the first output unit 311 to the first VRAM 331 based on the control signal of the overall control microcomputer 360. Therefore, in the first VRAM 331, an image for displaying the title display 351 and the like is generated. An image to be displayed on the driver's seat side is generated.

  In addition, the selection unit 330 selects the video signal from the second output unit 312 and the video signal from the third output unit 321 based on the control signal of the overall control microcomputer 360, and stores it in the second VRAM 332. Output. Accordingly, the second VRAM 332 generates an image of the equalizer display 353 together with the title display 351 and the like. An image to be displayed on the passenger seat side is generated.

  Thereafter, the synthesizing unit 333 synthesizes the two video signals so as to be alternately arranged in units of pixels. The LCD 340 displays the synthesized video signal. Then, by the parallax barrier 108 of the LCD 340, a title display 351 being currently reproduced and a reproduction time display 352 are displayed on the driver's seat side (FIG. 14A), and a title display 351 being currently reproduced is displayed on the passenger seat side. And an equalizer display 353 are displayed (FIG. 14B).

  As described above, in the third embodiment, the title display 351 or the like is displayed on the driver seat side and the equalizer display 353 is further displayed on the passenger seat side at a time, so that the display device 300 does not perform a screen switching operation. A lot of information can be displayed. In addition, the characters and display are not made too small to be difficult to see. Further, minimum information regarding audio reproduction can be displayed on the driver's seat side, and information excellent in entertainment properties (equalizer display 353 in this embodiment) can be displayed on the passenger seat side.

  Of course, the title display 351 and the equalizer display 353 are displayed on the driver seat side, and the title display 351 and the reproduction time display 352 can be displayed on the passenger seat side. For example, by operating the operation unit 370, the selection unit 330 causes the video signal (title display 351 and playback time display 352) from the first output unit 311 to be output to the second VRAM 332 and the second output unit 312. The video signal (title display 351 and playback time display 352) and the video signal (equalizer display 353) from the third output unit 321 can be switched so as to be output to the first VRAM 331. Alternatively, it can be realized by changing the pixel arrangement in the synthesis unit 333 as in the first embodiment.

  In the third embodiment, the title 351 and the reproduction time 352 are displayed on the driver's seat side as items relating to audio. In addition to this, the name of a player who performs a song or the name of a singer who sings a song may be displayed. Any information may be displayed as long as the information necessary for the audio screen is displayed on the driver's seat side and information with excellent entertainment properties is displayed on the passenger seat side.

[Example 4]
Example 4 will be described. The fourth embodiment is an example of changing the display form of the audio screen as in the third embodiment. Specifically, the title display 351 and the reproduction time display 352 are displayed on the driver's seat side, and the playlist is further displayed on the passenger seat side. Is an example of displaying. A display example is shown in FIG.

  The overall configuration of the display device 300 is substantially the same as that of the third embodiment (FIG. 13). A video signal for displaying the title 351 and the playback time 352 is output from the first microcomputer 315, and a video signal for displaying the playlist 354 is output from the second microcomputer 325.

  A variety of playlists 354 can be generated. For example, as shown in FIG. 13, titles stored in a recording medium such as a CD, MD, and HD are read in the order of reproduction, generated by the generation unit 324, and output to the second microcomputer 325.

  In addition, the generation unit 324 may read all titles from the CD and output the titles to the second microcomputer 325 in advance, or the overall control microcomputer 360 or the second microcomputer may be edited by operating the operation unit 370. The title is stored in the memory in 325, read from the memory of the overall control microcomputer 360 or the second microcomputer 325 after editing, and output to the third and fourth output units 321 and 322 as playlists. Also good.

  Similar to the third embodiment, the first output unit 311 outputs the video signal from the first microcomputer 315 to the selection unit 330 as it is. Similarly to the third embodiment, the second output unit 312 changes the input video signal so that it can be displayed on a part of the entire screen of the LCD 340 and outputs it to the selection unit 330.

  Then, the selection unit 330 outputs the video signal from the first output unit 311 to the first VRAM 331 based on the control signal from the overall control microcomputer 360, and the second output unit 312 and the third output. The video signal from the unit 321 is output to the second VRAM 332.

  The first VRAM 331 stores a video signal that displays a title and a reproduction time. On the other hand, the second VRAM 332 stores a video signal for displaying the playlist 354 along with the display of the title and the reproduction time.

  Similar to the third embodiment, the synthesizing unit 333 synthesizes the video signals stored in the first VARM 331 and the second VRAM 332 by alternately rearranging them in units of pixels. The LCD 340 displays the rearranged images, and the currently displayed title display 351 and the playback time display 352 are displayed on the driver seat side by the parallax barrier 108 (FIG. 15A), and these are displayed on the passenger seat side. Are displayed 351 and 352, and a play list 354 is displayed (FIG. 15B).

  Also in this example, the display device 300 can display a lot of information because the playlist 354 is displayed at a time together with the title display 351 and the like without performing a screen switching operation. Further, since the title display 351 and the play list 354 displayed on the passenger seat side are also displayed while being divided into two screens, the screen is easy to see without being too small.

  Further, as in the third embodiment, the display device 300 displays the minimum necessary information (title 351 and playback time 352) on the driver's seat on the audio screen, and has excellent entertainment characteristics on the passenger's seat. Information (playlist 354) can be displayed.

  Also in the fourth embodiment, similarly to the third embodiment, the screen shown in FIG. 15B may be displayed on the driver's seat side, and the screen shown in FIG. 15A may be displayed on the passenger seat side. In addition, regarding the play list 354 in the screen, when a plurality of titles are displayed, the title of the currently reproduced song can be displayed in a different color from the others.

  Furthermore, if there are many titles in the playlist 354, it can be displayed in a distributed manner on both the driver seat side and the passenger seat side as in the first embodiment. In this case, the playlist displayed on the driver's seat side is output from the second microcomputer 325 to the third output unit 321, and the playlist displayed on the passenger seat side is output from the second microcomputer 325 to the fourth output unit. 322 to output. This can be realized by causing the selection unit 330 to output the output from the third output unit 321 to the first VRAM 331 and the output from the fourth output unit 322 to the second VRAM 332.

  Also in the fourth embodiment, the other examples described in the third embodiment can be implemented, and the same operational effects are achieved.

[Example 5]
Next, Example 5 will be described. The fifth embodiment is an example in which the audio display mode is changed between the driver seat side and the passenger seat side as in the third embodiment. Specifically, the title and the playback time are displayed on the driver's seat side in the same manner as in the third embodiment, and the lyrics of the currently played audio are displayed together with these displays on the passenger seat side. A display example of the screen is shown in FIG.

  The overall configuration of the display device 300 according to the fifth embodiment is the same as that of the third embodiment (FIG. 13). A video signal displaying a title and a reproduction time is output from the first microcomputer 315 to the first and second output units 311 and 312.

  The video signal for displaying the lyrics 355 is output from the second microcomputer 325 to the third and fourth output units 321 and 322. The video signal for the lyric display 355 is generated by the generation unit 324 reading out lyric information stored in a recording medium (for example, CD, MD, HD), for example. In addition, the lyrics 355 stored in advance in the second microcomputer 325 may be read and output.

  The first output unit 311 outputs the video signal from the first microcomputer 315 to the selection unit 330 as it is, as in the fourth embodiment. Similarly to the third embodiment, the second output unit 312 is also displayed on a part of the entire screen of the LCD 340 and outputs the input video signal to the selection unit 330.

  The third and fourth output units 321 and 322 change the video signal so that the lyrics 355 can be displayed on a part of the entire screen of the LCD 340 and output the video signal to the selection unit 330.

  The selection unit 330 outputs the video signals (title display 351 and playback time display 352) from the first output unit 311 to the first VRAM 331 based on the control signal from the overall control microcomputer 360. In addition, the selection unit 330, based on a control signal from the overall control microcomputer 360, outputs a video signal (title display 351 and playback time display 352) from the second output unit 312 and a video from the third output unit 321. The signal (lyrics 355) is output to the second VRAM 332.

  The video signals stored in the first VRAM 331 and the second VARM 332 are combined by the combining unit 333 so as to be rearranged in units of pixels. Then, the parallax barrier 108 of the LCD 340 displays a title display 351 and a reproduction time display 352 on the driver's seat side (FIG. 16A), and lyrics 355 are displayed together with these displays on the passenger seat side ( FIG. 16 (B)).

  Also in this example, the display device 300 can display a lot of information because the lyrics 355 are displayed together with the title display 351 and the like without performing a screen switching operation. In addition, since the title 351 and the lyrics 355 displayed on the passenger seat side are displayed in two screens, the screen is easy to see without being too small. Further, the display device 300 displays the minimum necessary information (title 351 and playback time 352) on the audio screen on the driver's seat side, and information (lyrics 355) with excellent entertainment properties on the passenger seat side. Can be displayed.

  As in the fourth embodiment, the operation unit 370 can be operated to display the image displayed on the driver seat side and the passenger seat side, and the image displayed on the passenger seat side can be displayed on the driver seat side. . The displayed lyrics 355 may be changed in color according to the music being reproduced.

  Also in the fifth embodiment, the other examples described in the third embodiment can be carried out, and the same effects can be obtained.

[Example 6]
Next, Example 6 will be described. The sixth embodiment is an example in which the operation menu is displayed separately on the driver's seat side and the passenger seat side. Specifically, a menu image is displayed on the driver's seat side, and a menu image in a lower hierarchy is displayed on the passenger seat side.

  FIG. 17 is an example of an overall configuration diagram of the display device 300 according to the sixth embodiment. Compared with FIG. 1, the display device 300 is configured without the navigation RGB video signal output unit 320 and the third and fourth output units 321 and 322. Other than that, the configuration is substantially the same as in the first embodiment.

  FIG. 18 is an example of a display screen displayed on the LCD 340. An operation menu is displayed on the driver's seat side (FIG. 18A). A plurality of items 356 are displayed on the menu screen. In this item 356, “GS” means a gas station, and “SC” indicates a service center such as a dealer.

  On the other hand, a menu image at a lower level of the operation menu on the driver's seat side is displayed on the passenger seat side (FIG. 18B). Although a plurality of items 357 are displayed, each item 357 is an item in a lower hierarchy than the item 356 on the driver's seat side.

  As shown in FIG. 18A, the focus button is assigned to the “meal” item in the screen on the driver's seat side. Then, a lower-level menu image for this “meal” item is displayed on the passenger seat side (FIG. 18B). Therefore, when the focus button is moved to another item, a menu image in a lower hierarchy of the item is displayed on the passenger seat side. This movement of the focus button is performed by operating the operation unit 370, for example.

  The operation of the display device 300 will be described using the display screen shown in FIG. 18 as an example. First, the microcomputer 310 outputs a video signal for displaying an operation menu image on the driver's seat side to the first output unit 311 based on a control signal from the overall control microcomputer 360. Such a video signal is stored in a memory in the microcomputer 310, for example.

  In addition, the microcomputer 310 outputs a video signal for displaying a lower-level operation menu image to the second output unit 312 based on a control signal from the overall control microcomputer 360. For example, such a video signal is also stored in a memory in the microcomputer 310.

  The first output unit 311 outputs the video signal of the operation menu image on the driver's seat side to the selection unit 330, and the second output unit 312 outputs the video signal of the operation menu image on the passenger seat side to the selection unit 330.

  Based on the control signal from the overall control microcomputer 360, the selection unit 330 sends the video signal (driver's seat side operation menu image) from the first output unit 311 to the first VRAM 331 and the second output unit 312. Is output to the second VRAM 332 (operation menu image on the passenger seat side).

  The synthesizer 333 synthesizes the video signal from the first VRAM 331 and the video signal from the second VRAM 332 by alternately rearranging them in pixel units. Then, due to the parallax barrier of the LCD 340, the operation menu image shown in FIG. 18A is displayed on the driver's seat side, and the lower-level operation menu image shown in FIG. 18B is displayed on the passenger seat side.

  As described above, the display device 300 according to the sixth embodiment can display the operation menu images of the upper hierarchy and the lower hierarchy at the same time on the driver seat side and the passenger seat side without performing the screen switching operation. A lot of information can be displayed. In addition, even when an item is determined from the operation menu, it is only necessary to determine the item from the displayed menu, so that the screen switching operation is not performed many times and the time and effort can be saved. Furthermore, since the displayed characters are also displayed on the entire screen, the screen is easier to see compared to the case where the characters are divided into a plurality of screens and displayed in a small size.

  The displayed items may be determined by joint work between the driver's side passenger and the passenger's side passenger. For example, the item is determined by operating the operation unit 370.

  In the sixth embodiment, an example in which operation menus distributed from two viewpoint positions on the driver's seat side and the passenger's seat side are described has been described. In addition, the operation menus distributed from three or more viewpoint positions can be displayed in the same manner as the example described in the first embodiment.

  Further, the other examples described in the first embodiment and the like can also be applied in the sixth embodiment, and the same effects can be obtained.

[Example 7]
Next, Example 7 will be described. The seventh embodiment is an example in which the contents of information provided on the driver seat side and the passenger seat side are changed. For example, simple information is displayed on the driver's seat side, and detailed information is displayed on the passenger seat side.

  The overall configuration of the display device 300 according to the seventh embodiment is substantially the same as that of the first embodiment (FIG. 10). The difference is that the microcomputer 310 outputs a video signal for displaying simple information to the first output unit 311, and outputs a video signal for displaying detailed information to the second output unit 312.

  An example of the display screen is shown in FIG. It is the example of a screen which made the facility an example as a kind of information. A navigation map 345 is displayed on both the driver's side and the passenger's side, and simple facility information 358 (facility name and current sales information) is displayed on the driver's side, while details are displayed on the passenger's side. Information 359 (facility name, opening hours, admission fee, etc.) of the facility is displayed.

  The operation will be described below using the display screen shown in FIG. 19 as an example. The microcomputer 310 outputs a video signal for displaying the simple information 358 to the first output unit 311. The first output unit 311 changes the video signal to a size displayed on a part of one screen of the LCD 340 and outputs the video signal to the selection unit 330.

  Similarly, the microcomputer 310 outputs a video signal for displaying the detailed information 359 to the second output unit 312. The second output unit 312 changes the video signal so that it can be displayed on a part of one screen of the LCD 340 and outputs it to the selection unit 330. Video signals for displaying these pieces of information 358 and 359 are stored in a memory in the microcomputer 310, for example.

  The RGB video signal output unit 320 outputs the RGB video signal for navigation to the third output unit 321 and the fourth output unit 322. Similarly, the third and fourth output units 321 and 322 output the RGB video signal that can be displayed on a part of one screen of the LCD 340 to the selection unit 330.

  The selection unit 330 is based on a control signal from the overall control microcomputer 360, and a video signal from the first output unit 311 (video signal for displaying the simple information 358) and a video from the third output unit 321. A signal (RGB video signal for navigation) is output to the first VRAM 331.

  The selection unit 330 also receives a video signal from the second output unit 312 (video signal for displaying the detailed information 359) and a fourth output unit 322 based on a control signal from the overall control microcomputer 360. The video signal (RGB video signal for navigation) is output to the second VRAM 332.

  The first VRAM 331 synthesizes the video signal for displaying the simple information 358 and the RGB video signal for navigation so that the video can be displayed on one screen on the driver's seat side, and the video signal is combined with the synthesizer To 333.

  On the other hand, the second VRAM 332 synthesizes the video signal for displaying the detailed information 359 and the RGB video signal for navigation so that the video can be displayed on one screen on the passenger seat side. The data is output to the combining unit 333.

  The synthesizer 333 synthesizes the video signal from the first VRAM 331 and the video signal from the second VRAM 332 so that they are alternately rearranged in units of pixels.

  The parallax barrier 108 of the LCD 340 displays the navigation map image 345 and the facility list simple information 358 on the driver seat side (FIG. 19A), and the navigation map image 345 on the passenger seat side. And detailed information 359 of the facility list are displayed (FIG. 19B).

  As described above, in the seventh embodiment, the display device 300 can display the simplified information 358 and detailed information 359 regarding the facility together with the map image 345 for navigation, and therefore, without performing a screen switching operation. Information can be displayed. Further, since the simple information 358 and the detailed information 359 are displayed on each screen divided into two screens on the driver's seat side and the passenger seat side, respectively, they are displayed on a screen divided into three or more screens. Compared with, the size of each character and the like is also large and very easy to see.

  In the seventh embodiment, the simple information 358 and the detailed information 359 are displayed regarding the facility information. However, the displayed information is not limited to this, and simple information 358 regarding the traffic information may be included. Further, information related to menu display and simple information 358 related to various other information may be displayed. In any case, the microcomputer 310 can output the video signal for displaying the simple information 358 to the first output unit 311 and the video signal for displaying the detailed information 359 to the second output unit 312.

  In the seventh embodiment, the simple information 358 is displayed on the driver's seat side and the detailed information 359 is displayed on the passenger seat side. However, as in the first embodiment, the simple information 358 is displayed on the passenger seat side. May be displayed on the driver's seat side. This can be realized in the same manner as in the first embodiment.

  Furthermore, the other examples described in the first embodiment can also be realized in the seventh embodiment, and the same effects can be obtained.

[Example 8]
Next, Example 8 will be described. In the first to seventh embodiments, an example of a distributed information display screen (hereinafter, “dedicated screen”) and how to display the dedicated screen have been described. In the following, the case where the dedicated screen is displayed will be described.

  The first example is an example in which a dedicated screen is displayed when a passenger is present in the passenger seat upon receiving an operation input. FIG. 20 is a flowchart showing the operation of this example. First, the overall control microcomputer 360 starts this operation when the power is turned on (S10).

  Next, the overall control microcomputer 360 detects an occupant on the driver's seat side (S11). For example, an occupant is detected by an occupant detection sensor 380 (see FIG. 10 and the like). When an occupant is detected, an occupant detection signal is output from the occupant detection sensor 380 to the overall control microcomputer 360. Based on this detection signal, the overall control microcomputer 360 detects an occupant.

  Next, the overall control microcomputer 360 determines whether or not an input operation has been performed (S12). For example, when the operation unit 370 is operated and an input operation is performed on the display device 300, an operation signal is output from the operation unit 370 to the overall control microcomputer 360. It is determined whether or not this operation signal is input to the overall control microcomputer 360.

  If there is no input operation (NO in S12), the process returns to S11 again and the above process is repeated. On the other hand, if there is an input operation (YES in S12), the overall control microcomputer 360 determines whether there is a passenger on the passenger seat side (S13). For example, since a detection signal indicating that the passenger detection sensor 380 detects that the passenger is detected is output from the passenger detection sensor 380, the overall control microcomputer 360 determines this by detecting this.

  If there is a passenger (YES in S13), the overall control microcomputer 360 displays a dedicated screen (S14). The display of the dedicated screen is performed by the operation described in the first to seventh embodiments.

  On the other hand, when there is no passenger (NO in S13), the overall control microcomputer 360 performs normal screen display (S15). The normal screen display is a screen on which distributed information is not displayed on the passenger seat side. For example, this can be realized by controlling the overall control microcomputer 360 to output the selected video signal to the first VRAM 331 and not to the second VRAM 332 with respect to the selection unit 330.

  After the screen display (after S14 and S15), the overall control microcomputer 360 determines whether the power is turned off (S16). When the power is turned off (YES), the overall control microcomputer 360 terminates the series of processes (S17), and when the power is not turned off (NO in S16), the above-described processes are repeated.

  In this example, whether or not to display a dedicated screen is determined depending on whether or not a passenger is present in response to an input operation. As a next example, an example will be described in which the display of the dedicated screen is determined depending on whether a passenger is present regardless of the input operation.

  FIG. 21 is a flowchart showing the operation. The same operations as those in FIG. 20 are denoted by the same reference numerals. In this case, the overall control microcomputer 360 detects an occupant (S11), and if there is a passenger (YES in S13), a dedicated screen is displayed (S14). If there is no passenger (NO in S13), the normal screen is displayed (S15). In this operation, compared with FIG. 20, there is no input operation (S12).

  The following example is an example in which the dedicated screen is displayed according to the traveling state of the vehicle on which the display device 300 is mounted.

  FIG. 22 is a flowchart showing the operation. The same operations as those in FIG. 20 are denoted by the same reference numerals. The overall control microcomputer 360 detects an occupant (S11), and if the passenger is in the vehicle (YES in S13), it detects whether or not the vehicle is traveling (S131). Whether or not the vehicle is running is determined by, for example, the overall control microcomputer 360 detecting the engine speed, the tire speed, and the like.

  If the vehicle is not running (NO), the overall control microcomputer 360 displays a linkage screen or a screen having substantially the same amount of information (S132). The cooperation screen is a screen for determining items displayed in cooperation between the driver side and the passenger side among the dedicated screens. 12 is a screen corresponding to Example 6 (FIG. 18).

  In addition, the screens having substantially the same information amount are screens having substantially the same information amount of information displayed on the driver's seat side and the passenger seat side. 2 (FIG. 12) corresponds to Example 6 (FIG. 18).

  In other words, when the vehicle is stopped, the screens with substantially the same amount of information are displayed on the driver seat side and the passenger seat side, and the items can be determined smoothly by cooperation between the two.

  On the other hand, if the vehicle is running (YES in S131), the overall control microcomputer 360 displays a screen with a different amount of information or a dedicated screen only for one (S133).

  The screens with different information amounts are screens with different information amounts of information displayed on the driver's seat side and the passenger's seat side. Example 3 (FIG. 14), Example 4 (FIG. 15), This corresponds to Example 5 (FIG. 16) and Example 7 (FIG. 19).

  The one-only screen is a case where the dedicated screen is displayed only on either the driver seat side or the passenger seat side.

  That is, when the vehicle is running, a screen with a large amount of information is displayed on the passenger seat side, and a screen with a small amount of information is displayed on the driver seat side. Alternatively, a dedicated screen is displayed only on the passenger seat side, and a navigation map image 345 (or a travel regulation screen or the like) is displayed on the driver seat side.

  Such an operation can be executed, for example, by selecting a video signal so that each screen can be displayed in the selection unit 330 when the overall control microcomputer 360 detects each traveling state.

  As described above, in the display device 300, the type of the dedicated screen displayed can be changed according to the traveling state of the vehicle.

  In this example, when the vehicle is running, a screen with a small amount of information is displayed on the passenger seat side, and a screen with a large amount of information is displayed on the driver seat side. A screen with a large amount of information may be displayed on the driver's seat side, or a dedicated screen may be displayed only on the driver's seat side.

[Other embodiments]
In the first, second, and seventh embodiments described above, the navigation map image 345 has been described as being displayed on the driver seat side and the passenger seat side. In addition to the navigation image, for example, it may be a TV video or a playback video by DVD. In the case of TV video, if the TV signal (including not only analog but also digital) received by the TV receiver is output to, for example, the third and fourth output units 321 and 322, the same as in the first embodiment or the like. It can be implemented. In the case of a DVD, the video signal from the DVD playback device may be output to the third and fourth output units 321 and 322.

  In this case, the switching of the dedicated screen according to the traveling state described in the eighth embodiment may be applied so that the TV image or the like is not output to the driver seat side while the vehicle is traveling. The selection unit 330 may be configured not to output the video signals from the third and fourth output units 321 and 322 to the first VRAM 331 or the like.

  Further, in this case, instead of displaying a TV image or the like on the driver's seat side, a travel restriction image may be displayed. For example, in FIG. 10, the output from the microcomputer 310 that stores the travel restriction image is configured to be input to the fourth output unit 322, and the overall control microcomputer 360 receives the output from the fourth output unit 322 while the vehicle is traveling. This can be executed by controlling the selection unit 330 so as to output the output to the first VRAM 331. In this case, the distributed information is output from the microcomputer 310 to the first and second output units 311 and 312 as in the first embodiment.

  Furthermore, navigation map images can be separately output on the driver's seat side, and TV images and the like can be separately output on the passenger seat side. For example, the output of the navigation RGB video signal output unit 320 may be connected only to the third output unit 321, and a video signal such as a TV video may be input to the fourth output unit 322.

  In any case, it is possible to provide the display device 300 in which the amount of information that can be displayed is increased without performing a screen switching operation.

  In the first to eighth embodiments described above, the display device 300 has been described as displaying information distributed by a single LCD 340. In addition, for example, a plurality of LCDs 340 may be provided, and information may be displayed in a distributed manner on each LCD 340. Information that can be viewed at each viewpoint position is displayed on each LCD 340.

  Further, in the first to eighth embodiments, it has been described that an image is displayed by the LCD 340. However, the present invention can be applied to a plasma display, an EL display (Electro-luminescence display), and a cold cathode flat panel display. In either case, the same effects as those of the above-described embodiment can be obtained.

  Furthermore, in the above-described first to eighth embodiments, the case where the display device 300 according to the present invention is applied to a car navigation device has been described. In addition to this, for example, various devices such as a game device and a personal computer can be applied, and the same effects as the above-described example can be obtained.
