JP-A-2005-71286

  As a technique for realizing a dual view display, there are a technique using a parallax barrier and a technique using a lenticular lens. FIG. 7 is a diagram for explaining the principle of a dual view display using a parallax barrier. As shown in FIG. 7, the dual view display is configured by a combination of a switch liquid crystal 101 and a TFT (Thin Film Transistor) liquid crystal 102.

  The switch liquid crystal 101 is provided with a plurality of optical parallax barriers 103 at equal intervals. The parallax barrier 103 controls the traveling direction of light (liquid crystal backlight) and separates the light so that different lights reach the left and right observation positions 106 and 107. Further, in the TFT liquid crystal 102, the left image and the right image are alternately displayed on the left pixel group 104 and the right pixel group 105 which are alternately arranged.

  Light that passes through the parallax barrier 103 and passes through the left pixel group 104 reaches the left observation position 106, and light that passes through the parallax barrier 103 and passes through the right pixel group 105 reaches the right observation position 107. Thereby, on the display screen of one TFT liquid crystal 102, different images can be seen depending on the viewing direction.

  Incidentally, some devices using a liquid crystal display panel can operate an image displayed on the liquid crystal display panel not only by operating a remote controller but also by operating a touch panel. The touch panel is superimposed on the front surface of the liquid crystal display panel, and touch operation control can be performed by touching a bar, a key switch, or the like corresponding to an operation selection instruction displayed on the liquid crystal display panel.

  The touch panel can be applied to the above-described dual view display. However, in this case, it is necessary to allow the driver and passengers in the front passenger seat to independently operate the images displayed for them, in addition to the “left and right independent display” characteristic of the dual view display. There is. In addition, it is necessary to identify whether the person who touched the touch panel is a driver or a passenger, and to make the operation of the touch panel correspond to an image viewed by the driver or the passenger.

  In the invention described in the above-mentioned Patent Document 1, a device is devised for easily and surely determining which video the touch operation is effective for. That is, a viewer A touch-dedicated area and a viewer B touch-dedicated area are provided on the touch panel, and it is determined which area is touched, and an operation menu for the video corresponding to the touched area is displayed. Like to do.

  By the way, when using the navigation device, it is necessary to perform an operation for giving a desired instruction to the navigation device using a touch panel or the like. However, it is not desirable from the viewpoint of safety that the driver performs an operation while traveling, and it is prohibited by law. For this reason, the conventional navigation device is configured to limit the reception of operations (invalidate operations) while it is detected that the vehicle is running.

  However, in the case of a passenger in the passenger seat, although there is no safety problem even during operation while traveling, in the conventional navigation device, operation with respect to the navigation device is completely prohibited during traveling, and the operation can be performed even by the passenger. It will not be possible at all. In other words, for example, when a navigation video is displayed on the driver's seat side with a dual view display and a TV image or a DVD video is displayed on the passenger seat side, neither the driver nor the passenger can operate the navigation device at all. was there.

  The present invention has been made to solve such a problem, and even when different images are displayed on the driver's seat side and the passenger's seat side on the multi-view display, the passenger is free to make his / her own will. The purpose of this is to make it possible to perform operations on the image on the driver's seat side while driving.

To solve the problems described above in the present invention, by Rukoto multiple different images are multi-view display is divided into different directions, as can be seen different images depending on the direction to observe the entire display screen When a touch operation is performed on the configured touch panel of the display unit, it is detected whether the operator is a driver or a passenger, and the operation target is a driver based on the touch operation. Whether it is a video for a passenger or a video for a passenger, and an operation menu related to the video to be operated is displayed only on the detected display screen for the operator.

According to the present invention configured as described above, either the operation menu for the driver's image or the operation menu for the passenger's image is selected based on the operator's touch operation. The driver can select by touch operation whether to display the operation menu for the driver's image or the operation menu for the passenger's image. Apart from this, since it is also detected whether the operator is a driver or a passenger, the operation menu selected by the operator can be displayed only on the display screen of the operator himself / herself. Accordingly, even when different images are displayed for the driver and the passenger on the multi-view display, the passenger can operate the driver image on his / her own will.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of an in-vehicle electronic device according to the first embodiment. The on-vehicle electronic device shown in FIG. 1 shows an audio integrated car navigation device 10 having, for example, a navigation function and an AV (Audio Visual) playback function as an example.

  As shown in FIG. 1, the audio integrated car navigation device 10 according to the first embodiment includes a navigation control unit 11, a DVD control unit 12, a TV control unit 13, a video selection unit 14, a display control unit 15, a display device ( A dual view display) 16 and a controller 17.

  The navigation control unit 11 detects the current position of the vehicle using a self-contained navigation sensor, a GPS receiver, etc., and performs driving guidance by reading out map data in the vicinity of the vehicle position from a recording medium and displaying it on the screen. It is. The navigation control unit 11 outputs map image data.

  The DVD control unit 12 reproduces and outputs image data recorded on a DVD. DVD image data is output from the DVD control unit 12. The TV control unit 13 receives and processes TV broadcast radio waves. Television image data is output from the TV control unit 13.

  The video selection unit 14 inputs map image data output from the navigation control unit 11, DVD image data output from the DVD control unit 12, and television image data output from the TV control unit 13. Or one or two are selectively output.

  The display control unit 15 displays video on the dual view display 16 by outputting image data necessary for display to the dual view display 16 based on the image data output from the video selection unit 14. The display control unit 15 also performs control related to menu display as will be described later.

  The dual view display 16 includes a display panel 16a (corresponding to a display unit of the present invention), a touch panel 16b (corresponding to a touch detection unit of the present invention), and a touch position detecting unit 16c. The display panel 16a displays a video based on image data, and is configured as shown in FIG. 7, for example, and can perform dual view display based on a plurality of different videos. In the dual view display, the two images selected by the image selection unit 14 are displayed separately in the left direction and the right direction, so that the driver and the passenger can view different images.

  For example, when the right seat is the driver's seat, the video selection unit 14 selects map image data and DVD image data, outputs the DVD image data to the left pixel group 104, and maps the map image data to the right pixel group 105. Is displayed on the driver's seat side navigation video (corresponding to the driver's image of the present invention), and the passenger's seat side displays DVD video (corresponding to the passenger's image of the present invention). It becomes possible to do. Which video source is to be selected on the driver's seat side and the passenger's seat side can be determined by operating a source selection switch (not shown) by the driver and the passenger on the passenger seat.

  The video selection unit 14 selects any one image data and outputs it to the left pixel group 104 and the right pixel group 105, so that the same video can be viewed from both the driver's seat and the passenger seat. It is also possible to make it possible.

  The touch panel 16b is superimposed on the front surface of the display panel 16a, and detects a touch operation by a user (driver or passenger in the passenger seat). Here, in order to detect whether or not the user touches the touch panel 16b, for example, a resistance film method or an infrared method is used. The touch position detection unit 16c detects the touch position of the user on the touch panel 16b and outputs the coordinate data.

  The display control unit 15 displays the navigation video for the driver and the DVD video for the passenger when different video sources are selected on the driver side and the passenger side in the dual view display. A predetermined menu is displayed on the display panel 1a so as to overlap the display of these images or in a different area from these images. At this time, the display control unit 15 controls to display the passenger menu and the driver menu at different screen positions of the display panel 16a.

  The controller 17 controls the entire audio integrated car navigation device 10. The controller 17 is configured by a microcomputer including a CPU, a ROM, and a RAM, for example. Various programs for controlling the audio-integrated car navigation device 10 are stored in the ROM. The CPU executes various controls while using the RAM as a work memory in accordance with various programs stored in the ROM.

  The controller 17 includes an operator detection unit 17a and an operation target detection unit 17b as functional configurations realized by the operation of the microcomputer. The operator detection unit 17a is a passenger or a driver based on the coordinate data of the touch position output from the touch position detection unit 16c when the touch operation is detected by the touch panel 16b. To detect. Further, the operation target detection unit 17b determines whether the operation target is an image for a passenger based on the coordinate data of the touch position output from the touch position detection unit 16c when the touch operation is detected by the touch panel 16b. Detect whether the video is for the driver.

  The display control unit 15 controls the display screen of the operator detected by the operator detection unit 17a to display an operation menu related to the operation target video detected by the operation target detection unit 17b. The display screen of the operator refers to a display screen for the left seat displayed on the entire display panel 16a by image data output to the left pixel group 104 when the operator is a passenger. Further, when the operator is a driver, it means a display screen for the right seat displayed on the entire display panel 16 a by image data output to the right pixel group 105.

  FIG. 2 is a diagram illustrating an example of a display screen displayed on the display panel 1a in the first embodiment. Here, FIG. 2A shows the transition state from the first layer to the third layer of the display screen for the left seat (passenger), and FIG. 2B shows the display screen for the right seat (driver). The transition state from the first hierarchy to the third hierarchy is shown. The first hierarchy is a screen that is displayed when the user is not performing any operation on the touch panel 16b. On the other hand, the second layer and the third layer are screens displayed when a menu is touched on either the left seat display screen or the right seat display screen.

  As shown in FIG. 2 (a), in the first hierarchy of the left seat display screen, as a passenger menu, a first operation item 21a for specifying that the operator is a passenger (this display) The area corresponds to the first area of claim 2) is displayed near the left end of the screen. Further, as shown in FIG. 2B, in the first layer of the right seat display screen, as a driver menu, a second operation item 21b (for specifying that the operator is a driver) This display area corresponds to the second area of claim 2) is displayed near the right edge of the screen.

  As described above, since the first operation item 21a and the second operation item 21b are displayed at different positions on the display screen, depending on which operation item is touched, the operator is a passenger. It is possible to determine whether the vehicle is a driver. That is, the operator detection unit 17a operates based on the coordinate data output from the touch position detection unit 16c depending on which area of the first operation item 21a or the second operation item 21b is touched. Whether the passenger is a passenger or a driver.

  In the first hierarchy, both the first operation item 21a and the second operation item 21b are effective and can be operated by arbitrarily touching the operation item desired by the user (however, while traveling) The operation for the second operation item 21b is invalidated). In contrast, when any operation item is touched in the first hierarchy, the touched operation item is not touched depending on whether the operation item is the first operation item 21a or the second operation item 21b. The operation for the operation item is invalidated.

  Invalidation means a state in which a touch operation is not accepted. On the screen, for example, the invalidated menu is masked and displayed. Alternatively, the invalidated menu may be hidden. Here, the mask display means that the menu is displayed in a mode different from the display when the operation is effective, for example, the menu is displayed thinner than usual (indicated by a dotted line in FIG. 2).

  FIG. 2 shows an example in which the first operation item 21a for the passenger is touched in the first hierarchy (the touched operation item is indicated by hatching). In this case, the operator detection unit 17a detects that the first operation item 21a is touched based on the coordinate data output from the touch position detection unit 16c, and determines that the operator is a passenger. . At this time, the controller 17 continues to enable the menu operation on the left seat display screen and invalidates the menu operation on the right seat display screen. Then, the display control unit 15 makes a transition to the second layer display.

  In the second hierarchy, the display control unit 15 displays the passenger's DVD image and the driver on the display screen for the left seat of the operator (passenger in the example of FIG. 2) detected by the operator detection unit 17a. The navigation video for use is divided and displayed. Here, the passenger DVD image is displayed in the left half area of the screen, and the driver navigation image is displayed in the right half area of the screen. On the other hand, in the second hierarchy, the right seat display screen still displays the same navigation video as in the first hierarchy.

  In the left half area of the left seat display screen, a third operation item 22a for designating that the operation target is a DVD image for a passenger (this display area corresponds to the third area of claim 3). Is displayed near the left edge of the left half area. Further, in the right half area of the left seat display screen, a fourth operation item 22b for designating that the operation object is a navigation video for the driver (this display area is the fourth area of claim 3). Is displayed near the right edge of the right half area.

  Thus, since the third operation item 22a and the fourth operation item 22b are displayed at different positions on the display screen, the operation target is a DVD for passengers depending on which operation item is touched. It is possible to determine whether the image is a video or a navigation video for a driver. In other words, the operation target detection unit 17b determines whether the operation target is based on which area of the third operation item 22a or the fourth operation item 22b is touched based on the coordinate data from the touch position detection unit 16c. It is determined whether the DVD image is for the passenger or the navigation image is for the driver. Then, the display control unit 15 shifts to the display of the third hierarchy so as to display the video according to the determination result.

  In the third hierarchy, the display control unit 15 displays an operation menu related to the operation target video detected by the operation target detection unit 17b on the display screen of the operator detected by the operator detection unit 17a. Here, an example is shown in which the fourth operation item 22b is touched in the second hierarchy. That is, the display control unit 15 displays the navigation image designated as the operation target and the operation menu 23 on the left seat display screen. When the third operation item 22a is touched in the second layer, the display control unit 15 displays the DVD video and its operation menu on the left seat display screen in the third layer. On the other hand, the right-seat display screen still displays the same navigation video as the first hierarchy in the third hierarchy.

  As described above, when the first operation item 21a is operated in the first hierarchy, the navigation video operation menu 23 is finally touched on the left seat display screen until the operation is completed, or the touch is performed for a predetermined time. The second operation item 21b on the right seat display screen continues to be invalidated until it is detected that no coordinate data is supplied from the position detection unit 16c. As described above, since the menu on the right seat display screen is invalidated in the second hierarchy and the third hierarchy, even if the position where the second operation item 21b is initially displayed is touched, the controller 17 The touch operation is regarded as an operation on the left seat display screen.

  The operation menu 23 displayed in the third hierarchy may be either a transition item for transitioning to a lower or higher hierarchy, or a function item for controlling the function or operation of the navigation control unit 11 that is a control target. There is always some kind of functional item at the bottom of the hierarchy. In addition, any of transition items and function items can be arranged in the uppermost layer or the middle layer of the hierarchical structure.

  When a series of operations related to the hierarchical operation menu 23 is completed, the navigation control unit 11 executes a process corresponding to the operation, and a navigation video reflecting the process result is displayed on the right seat display screen. The At this time, the video on the left seat display screen returns to the original DVD video. Note that while the series of operations for the navigation video is being performed on the left seat display screen, the playback of the DVD video may be temporarily stopped.

  FIG. 3 is a flowchart showing an operation example of the audio-integrated car navigation device 10 according to the first embodiment configured as described above, that is, a processing procedure of the menu providing method according to the first embodiment. In FIG. 3, the display control unit 15, as in the first hierarchy of FIG. 2, displays a passenger seat DVD image and a left seat display screen including a first operation item 21 a, a driver navigation image, and a first navigation image. The right-seat display screen including the second operation item 21b is displayed in dual view on the display panel 16a (step S1).

  Next, the controller 17 determines whether or not a touch operation has been performed on the touch panel 16b in accordance with the presence or absence of input of coordinate data from the touch position detection unit 16c (step S2). This determination is repeated until a touch operation is performed. When the controller 17 detects that the touch operation has been performed by inputting the coordinate data from the touch position detection unit 16c, the operator detection unit 17a performs the first operation based on the coordinate data of the touch position. It is determined which of the item 21a or the second operation item 21b is touched (steps S3 and S4).

  Here, when it is determined that the first operation item 21a is touched, the operator detection unit 17a determines that the operator is a passenger. In response to this, the controller 17 invalidates the menu operation on the driver's right seat display screen (step S5). At this time, the menu operation on the left seat display screen remains valid. In addition, the display control unit 15 displays the passenger DVD image and the driver navigation image on the left seat display screen, which are divided into left and right parts (step S6). At this time, the video on the right seat display screen remains the navigation video.

  On the other hand, when it is determined that the second operation item 21b is touched, the operator detection unit 17a determines that the operator is a driver. In response to this, the controller 17 invalidates the menu operation on the passenger's left seat display screen (step S7). At this time, the menu operation on the right seat display screen remains valid. In addition, the display control unit 15 displays the passenger DVD image and the driver navigation image on the right seat display screen, which are divided into left and right parts (step S8). At this time, the video on the left seat display screen remains the DVD video.

  When the operation on the touch panel 1b detected in step S2 is neither an operation on the first operation item 21a nor an operation on the second operation item 21b, that is, an operation is input from the touch position detection unit 16c to the controller 17. If the coordinate data is neither the coordinates representing the area of the first operation item 21a nor the coordinates representing the area of the second operation item 21b, the touch operation itself is invalid, and the process returns to step S2. .

  After the DVD video and the navigation video are displayed in two on the left seat display screen or the right seat display screen in step S6 or step S8, the controller 17 receives the coordinate data from the touch position detector 16c. Whether or not a touch operation on the touch panel 16b has been performed is determined according to whether or not there is an input (step S9). This determination is repeated until a touch operation is performed.

  Here, the time from the detection of the touch operation on the touch panel 16b to the touch operation in step S2 until the touch operation in step S9 is measured. If the touch operation in step S9 is not detected within a predetermined time (timeout), the operation is continued. You may make it return to the process of step S1, judging that there is no intention to do.

  When the controller 17 detects that a touch operation has been performed by inputting coordinate data from the touch position detection unit 16c, the operation target detection unit 17b performs the third operation item 22a based on the coordinate data of the touch position. Alternatively, it is determined which of the fourth operation items 22b has been touched (steps S10 and S11).

  Here, when it is determined that the touch is performed on the third operation item 22a, the operation target detection unit 17b determines that the operation target is a DVD video for a passenger. In response to this, the display control unit 15 displays the passenger's DVD image and its operation menu 23 on the display screen of the operator who has been divided into two (step S12).

  On the other hand, when it is determined that the touch is performed on the fourth operation item 22b, the operation target detection unit 17b determines that the operation target is a navigation video for the driver. In response to this, the display control unit 15 displays the navigation video for the driver and the operation menu 23 on the display screen of the operator who has been divided and displayed (step S13).

  When the operation on the touch panel 1b detected in step S9 is neither the operation on the third operation item 22a nor the operation on the fourth operation item 22b, that is, the operation is input from the touch position detection unit 16c to the controller 17. If the coordinate data is neither the coordinates representing the area of the third operation item 22a nor the coordinates representing the area of the fourth operation item 22b, the touch operation itself is invalid, and the process returns to step S9. .

  Thereafter, the controller 17 determines whether or not a touch operation on the touch panel 16b has been performed in accordance with whether or not coordinate data is input from the touch position detection unit 16c (step S14). This determination is repeated until a touch operation is performed. Here, the time from the detection of the touch operation on the touch panel 16b in step S9 to the touch operation in step S14 is measured, and if the touch operation in step S14 is not detected within a predetermined time (timeout), the operation is continued. You may make it return to the process of step S1, judging that there is no intention to do.

  When the controller 17 detects that a touch operation has been performed by inputting coordinate data, the controller 17 determines which operation item in the operation menu 23 has been operated based on the coordinate data of the touch position. Then, control is performed so as to execute the process corresponding to the touched operation item (step S15). That is, when the touched operation item is a transition item, the display control unit 15 is controlled to display a menu of the transition destination hierarchy. When the touched operation item is a function item, the control target unit is controlled to execute the corresponding function or operation.

  And the controller 17 determines whether a series of operation was complete | finished (step S16). Specifically, it is determined whether a function item is touched and a process corresponding to the function item is executed. When the transition item is touched and the process in step S15 is performed, the operation returns to step S14 because there is still a continuing operation. If the next touch operation is not detected within a predetermined time after the transition item is touched, it is possible to determine that there is no intention to continue the operation in the same manner as described above and to return to the process of step S1. .

  On the other hand, when the function item is touched and the process of step S15 is performed, the menu operation invalidated in step S5 or step S7 is returned to the valid state, and the video displayed in step S12 or step S13 is stepped. The original image displayed in S1 is restored (step S17), and the process returns to step S1.

  As described above in detail, in the first embodiment, the first operation item 21a or the second operation item 21b in the first hierarchy is based on the coordinate data of the touch position output from the touch position detection unit 16c. An operator is detected according to which one is operated, and an operation target image is detected according to which one of the third operation item 22a or the fourth operation item 22b is operated in the second hierarchy. The operation menu related to the operation target image is displayed on the displayed display screen of the operator.

  With this configuration, the driver or passenger can select by touch operation whether to display the operation menu for the driver's image or the operation menu for the passenger's image, and operate the selected operation menu. Can be displayed on the user's own display screen. As a result, even when different images are displayed on the driver's display screen and the passenger's display screen on the dual view display, the passenger can operate the driver's image on his / her own will. It becomes. Therefore, it becomes possible to perform the operation assistance of the image displayed for the driver on the passenger seat side. Therefore, it is possible to perform an operation on the image for the driver while traveling while ensuring the safety of traveling.

  In the first embodiment, the first operation item 21a and the second operation item 21b are displayed in the first layer, but it is not always necessary to display them. For example, the area for designating that the operator is a passenger is set near the left end of the screen (for example, the same area as the display area of the first operation item 21a), and the operator is a driver. May be set near the right end of the screen (for example, the same area as the display area of the second operation item 21b). Alternatively, the left half of the screen may be set as an area for designating that the operator is a passenger, and the right half may be set as an area for designating that the operator is a driver.

  Similarly, it is not always necessary to display the third operation item 22a and the fourth operation item 22b in the second hierarchy. For example, an area for designating that the operation target is an image for passengers is set near the left end of the screen (for example, the same area as the display area of the third operation item 22a), and the operation target is the driver. An area for designating that the image is a video for use may be set near the right end of the screen (for example, the same area as the display area of the fourth operation item 22b). In addition, the left half of the screen is set as an area for designating that the operation target is a passenger video, and the right half is set as an area for designating that the operation target is a driver video. You may do it.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the configuration of the audio-integrated car navigation device 10 is the same as that in FIG. 1, but the operations of the display control unit 15 and the controller 17 are different from those in the first embodiment.

  FIG. 4 is a diagram illustrating an example of a display screen displayed on the display panel 1a in the second embodiment. Here, FIG. 4A shows the transition state from the first layer to the second layer of the left seat display screen, and FIG. 4B shows the state from the first layer to the second layer of the right seat display screen. The transition state is shown. The first hierarchy is a screen that is displayed when the user is not performing any operation on the touch panel 16b. On the other hand, the second hierarchy is a screen displayed when an operation item is touched on either the left seat display screen or the right seat display screen.

  As shown in FIG. 4 (a), in the first hierarchy of the left seat display screen, two operation items 41a and 42a (these display areas are displayed in the first area of claim 4 as passenger menus). Is displayed near the left edge of the screen. One operation item 41a is for designating a passenger's image as an operation target, and the other operation item 42a is for designating a driver's image as an operation target (one operation item). The display area 41a corresponds to the third area of claim 4, and the display area of the other operation item 42a corresponds to the fourth area of claim 4).

  In the first layer of the right seat display screen, two operation items 41b and 42b (these display areas correspond to the second area of claim 4) are provided near the right edge of the screen as a driver menu. Is displayed. One operation item 41b is for designating a passenger's image as an operation target, and the other operation item 42b is for designating a driver's image as an operation target (one operation item). The display area 41b corresponds to the third area of claim 4, and the display area of the other operation item 42b corresponds to the fourth area of claim 4).

  Thus, since the four operation items 41a, 41b, 42a, and 42b are displayed at different positions on the display screen, the operator is a passenger or a driver depending on which operation item is touched. And whether the operation target is a DVD image for a passenger or a navigation image for a driver.

  That is, the operator detection unit 17a determines which of the first region (operation items 41a and 42a) or the second region (operation items 41b and 42b) is based on the coordinate data output from the touch position detection unit 16c. It is determined whether the operator is a driver or a passenger depending on whether or not the touch is made. Further, the operation target detection unit 17b determines which of the operation items 41a and 42a is touched or which of the operation items 41b and 42b is touched based on the coordinate data output from the touch position detection unit 16c. Thus, it is determined whether the operation target is a DVD image for a passenger or a navigation image for a driver.

  FIG. 4 shows an example in which the operation item 42a in the first area is touched in the first layer. In this case, the operator detection unit 17a detects that the first area is touched based on the coordinate data output from the touch position detection unit 16c, and determines that the operator is a passenger. In addition, the operation target detection unit 17b detects that the operation item 42a has been touched, and determines that the operation target is a navigation video for the driver. In response to this, the display control unit 15 displays an operation menu 43 related to the navigation image for the driver on the left seat display screen for the passenger in the second hierarchy.

  As described above in detail, in the second embodiment, the operation item for designating the operator and the operation item for designating the operation target video are displayed together in the first hierarchy. The operator and the operation target video can be simultaneously designated only by the first level touch operation. As a result, the number of operations until the operation menu 43 is displayed can be reduced by one step compared to the first embodiment.

  In the second embodiment as well, the four operation items 41a, 41b, 42a, and 42b are not necessarily displayed. In other words, the operator designation area and the operation target video designation area may be set in the touch panel 16b without displaying these operation items 41a, 41b, 42a, and 42b.

(Third embodiment)
Next, a third embodiment according to the present invention will be described with reference to the drawings. FIG. 5 is a block diagram illustrating a configuration example of an audio-integrated car navigation device 50 according to the third embodiment. In FIG. 5, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here.

  As shown in FIG. 5, the audio integrated car navigation device 50 according to the third embodiment further includes a motion sensor 51 in addition to the configuration shown in FIG. 1. Further, instead of the controller 17 shown in FIG. 1, a controller 52 having a functional configuration different from this is provided. The controller 52 includes an operator detection unit 52a and an operation target detection unit 52b as functional configurations.

  FIG. 6 is a diagram illustrating an example of a display screen displayed on the display panel 1a in the third embodiment. 6A shows a transition state from the first layer to the second layer of the left seat display screen, and FIG. 6B shows a state from the first layer to the second layer of the right seat display screen. The transition state is shown. The first hierarchy is a screen that is displayed when the user is not performing any operation on the touch panel 16b. On the other hand, the second layer is a screen displayed when the menu is touched on either the left seat display screen or the right seat display screen.

  In the third embodiment, the display control unit 15 uses the first operation item 61a for designating that the operation target is a passenger image on both the left seat display screen and the right seat display screen. (This display area corresponds to the first area of claim 5) and the second operation item 61b for designating that the operation object is a video for the driver (this display area is of claim 5). Corresponding to the second area) are displayed at different screen positions. Based on the coordinate data output from the touch position detection unit 16c, the operation target detection unit 52b determines whether the operation target is an image for a passenger depending on which of the operation items 61a and 61b is touched. It is determined whether the video is for the driver.

  In such a configuration, since the same operation items 61a and 61b are displayed at the same position on the left seat display screen and the right seat display screen, the operator is discriminated based on the coordinate data of the touch position. I can't. In order to determine the operator, a motion sensor 51 is provided in the third embodiment.

  The motion sensor 51 detects a three-dimensional movement of an operator who performs a touch operation on the touch panel 16b, and can be realized by various means. For example, by irradiating infrared rays in the vicinity of the touch panel 16b and detecting changes in the infrared rays that occur when the operator's hand moves within the infrared irradiation area, it is possible to detect from either the driver side or the passenger side. It is possible to detect whether the operator's hand has entered the infrared irradiation area.

  Although an example using infrared rays has been described here, visible light, ultrasonic waves, or the like may be used. In addition, by installing a camera, photographing the vicinity of the touch panel 16b, and recognizing the captured image data, the operator's hand has entered the infrared irradiation area from either the driver's side or the passenger's side It is also possible to detect.

  The operator detection unit 52a determines whether the operator is a driver based on the detection result of the motion sensor 51, that is, whether the operation on the touch panel 16b is performed from either the driver seat side or the passenger seat side. Detect if you are a passenger. The display control unit 15 controls the transition of the display image of the left seat display screen and the right seat display screen according to the detection results by the operator detection unit 52a and the operation target detection unit 52b.

  FIG. 6 shows an example when the passenger touches the second operation item 61b in the first hierarchy. In this case, the operator detection unit 52a determines that the operator is a passenger based on the detection result of the motion sensor 51. In addition, the operation target detection unit 52b detects that the second operation item 61b is touched, and determines that the operation target is a navigation image for the driver. In response to this, the display control unit 15 displays the operation menu 62 relating to the navigation image for the driver on the left seat display screen for the passenger in the second hierarchy.

  As described in detail above, in the third embodiment, the operator is detected using the motion sensor 51, and the operation target image is detected based on the coordinate data of the touch position based on the touch operation in the first layer. Therefore, the operation target video can be designated by the first level touch operation, and at the same time, the operator can be specified. Thereby, the number of operations until the operation menu 62 is displayed can be reduced by one step compared to the first embodiment.

  In the third embodiment, it is not always necessary to display the operation items 61a and 61b. That is, the operation target image designation area may be set in the touch panel 16b without displaying these operation items 61a and 61b.

  Further, in the first to third embodiments, the example of the dual view display configured to be able to see two different images depending on the viewing direction on one display panel 16a has been described. The present invention can also be applied to a multi-view display configured to be able to see the above video.

  In addition, each of the first to third embodiments described above is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. It will not be. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
