Description

The present invention relates to a display device, and more particularly to a display device for providing independent and different information substantially simultaneously to a plurality of observers (users) on the same screen.

While the vehicle is traveling, the driver is prohibited from watching the television and movies, and the current display device cannot display the television or movies while the vehicle is traveling. For this reason, passengers other than the driver (for example, passengers next to the driver) cannot watch TV or movies while driving, even though they are not prohibited from watching TV or movies. .

On the other hand, in recent years, various technologies have been proposed for making display content for a driver different from display content for a passenger other than the driver in a display device mounted on a vehicle. For example, in Patent Document 1 below, as shown in FIG.
, It provided 303, although the light emitted from the Workspace window 304 for displaying the image for the driver's seat G _DR is incident on the eyes of the driver DR, the Workspace window 305 for displaying the passenger seat picture G _PA the emitted light is prevented from being incident on the eyes of the driver DR, while the light emitted from the Workspace window 305 for displaying the passenger seat picture G _PA is incident on the eyes of the passenger PA, operation Seat G
A technique is disclosed in which light emitted from the belt-shaped display unit 304 that displays _DR is not incident on the eyes of the passenger occupant PA.

Patent Documents 2 and 3 listed below also disclose a display device that can display two images simultaneously on a single liquid crystal display (LCD) and can view different images from the driver seat and the passenger seat. Yes. Patent Documents 4 and 5 listed below disclose a two-screen display device that simultaneously displays two types of images on the same screen.

By adopting the above-described technique, as shown in FIG. 35, the display device 306 displays the map image 307 by the navigation device so that it can be seen from the driver DR (so that it cannot be seen from the passenger occupant PA). The DVD image 308 can be displayed on the display device 306 so that it can be seen from the passenger seat occupant PA (so as not to be seen from the driver DR).
As a result, even when the vehicle is traveling, the passenger occupant PA can watch TV, movies, and the like.

By the way, in recent display devices, a touch panel is adopted, and an operation switch is created on the display screen. Therefore, when the display content for the driver is different from the display content for the occupant other than the driver, as shown in FIG. 36, the display image for the driver and the display image for the occupant other than the driver include It is conceivable that the operation switches B _{D1 to} B _D6 and B _{A1 to} B _A6 for each display content are displayed.

The operation switches B _{D1 to} B _D6 can be seen only by the driver, and the operation switches B _{A1 to} B _A6 can be seen only by the passenger on the passenger seat, but as shown in FIG. The switches B _{D1 to} B _D6 are arranged in areas P _{1 to} P ₆ that have the same operation area on the display screen as the operation switches B _{A1 to} B _A6 . In this way, arranging the operation switches in the same operation area in each video on the display screen is referred to as “same” or “overlap”.

Therefore, for example, whether the control (control to display the map image in detail) to be performed when the operation switch B _D5 “detail” is pressed when the region P ₅ on the display screen is pressed, or the operation switch B _{A5 It} is necessary to appropriately determine whether or not to perform control (control to stop reproduction of DVD video) performed when “Stop” is pressed. In other words, if this determination cannot be made properly, appropriate operation control desired by the user cannot be performed.

As will be described in detail later, disposing the operation switch in the same operation area in each image on the display screen is referred to as “same” or “overlap”, whereas the setting shown in FIG. Like the switches 41 _DR and 41 _PA , the release switches 42 _DR and 42 _PA , and the operation switches 49 _DR and 49 _PA , it is important to arrange the operation switches at different positions in the respective images on the display screen. "It must not be".

Means for solving the problems and their effects

The present invention has been made in view of the above problems, and even when individual information is displayed on the same screen for a plurality of viewing directions, for example, it can be seen from the direction in which the driver exists, A driver's seat image that cannot be seen from the direction in which the passenger is present and a passenger seat image that is visible from the direction in which the passenger is present but not visible from the direction in which the driver is present are displayed on the same screen. Even if it exists, it aims at providing the display apparatus with which appropriate operation control which a user desires is implemented.

In order to achieve the above object, the display device (1) according to the present invention includes an operation switch for information displayed with respect to the viewing direction on the driver's seat side and an operation for information displayed with respect to the viewing direction on the passenger seat side. The switch is displayed with a predetermined operation area at any position on the screen, and at least a part of the operation switch of information displayed for one viewing direction is displayed in the other viewing direction. Display means arranged so as to overlap with at least a part of the operation area of the operation switch of information displayed on the display, an operation input means for receiving an operation input to the operation switch, and an operation input to the operation switch of the reception, the information displayed to the direction as viewed in the driver's seat, and the information displayed for any particular viewing direction of the information displayed to the direction as viewed in the front passenger seat side And limiting means for limiting an operation input to respond, it is characterized in that it comprises a switching means for switching the specific viewing direction.

According to the display device (1), individual information is displayed on the same screen for each of a plurality of viewing directions. For example, as shown in FIGS. 11 and 12, which will be described later, a driver's seat video G _DR (for example, a map video by a navigation device) can be seen from the driver _DR , and a passenger seat video G can be seen from the passenger seat passenger PA. _PA (eg, DVD video) can be made visible.

However, as shown in FIGS. 11 and 12, the operation area on the display screen for the image for the driver's seat G _DR, and the operation area on the display screen for the passenger seat picture G _PA overlap the same region E
_When the operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA provided in _{7 to} E ₁₂ are operated, if there are no restrictions on the operation, the operation control that the user does not want is performed. May be done.

According to the display device (1), reception of an operation input to the operation switch is displayed with respect to the driver seat side viewing direction and information displayed with respect to the passenger seat side viewing direction. Are limited to operation inputs corresponding to information (video) displayed with respect to any specific viewing direction (for example, the direction in which the driver DR exists). Accordingly, the operation input corresponding to the information (video) displayed for the specific viewing direction is accepted, but the information (video) displayed for a viewing direction different from the specific viewing direction is received. The corresponding operation input is not accepted.

For example, when the viewing direction from the driver DR is set to the specific viewing direction, the operation area on the display screen for the driver seat image _GDR and the display screen for the passenger seat image _GPA When an operation is performed on the operation switches arranged so that the operation areas overlap, only the operation input corresponding to the driver seat image _GDR is valid, and the operation input corresponding to the passenger seat image _GPA is It becomes invalid. That is, the driver seat video _GDR becomes the priority video. Therefore, the user can prevent undesired operation control from being performed by knowing which of the priority images is set.

Also, if the operation area on the display screen for the image for the driver's seat G _DR, and operation of the operation area on the display screen for the passenger seat picture G _PA is to arranged the operation switch so as to overlap is performed Even so, since appropriate operation control can be realized by accepting an operation input corresponding to the priority video, the operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA shown in FIGS. As described above, it is possible to effectively use the display screen by disposing operation switches having different properties in the same region E _{7 to} E ₁₂ .

Further, according to the display device (1), since the specific viewing direction is switched and the priority image is not fixed, for example, an operation area on the display screen for the driver seat image _GDR , and a passenger seat The operation input to the operation switch arranged so that the operation areas on the display screen for the video image G _PA overlap with each other corresponds to the operation input corresponding to the driver seat image G _DR and the passenger seat image G _PA It can be switched by operation input. Therefore, the user can realize desired operation control by appropriately setting and switching the priority video, or by accurately recognizing which priority video is set.

Moreover, the display device (2) according to the present invention is displayed with respect to the information displayed with respect to the viewing direction on the driver seat side and the viewing direction on the passenger seat side in the display device (1). The information processing apparatus is characterized by comprising prohibiting means for prohibiting reception of an operation input corresponding to information displayed for a viewing direction different from any specific viewing direction.

When operation switches are provided in the same region E _{7 to} E _{12 as} in the operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA shown in FIGS. 11 and 12, some restrictions are added to the operation. If not, there is a possibility that operation control not desired by the user may be performed. However, unlike this, when they are provided in different areas where they do not overlap, it is possible to avoid the operation control not desired by the user from being performed even if the operation is not restricted.

However, the driver DR cannot see the passenger seat video G _PA , and the passenger seat passenger PA cannot see the driver seat video G _DR . Therefore, the driver DR is the passenger seat video G _PA
It is not possible to know the location of the operation switch provided on the driver DR is also going to touch the portion not provided with the operation switch, it is provided on the passenger seat picture G _PA Operation There is a risk of touching the switch. Therefore, the operation switch for accepting only operation input corresponding to the image for the driver's seat G _DR, as an operation switch for accepting only operation input corresponding to the video G _PA passenger seat was provided in different areas not overlapping each However, it is desirable to add some restrictions to the operation.

According to the display device (2), any one of the information displayed for the viewing direction on the driver's seat side and the information displayed for the viewing direction on the passenger seat side is a specific viewing direction. Acceptance of an operation input corresponding to information displayed for another viewing direction is prohibited. That is, the operation control corresponding to the operation corresponding to the video other than the priority video is not performed. For example, when the image for the driver's seat G _DR is set to the priority images, if the operation to the operation switches 49 _PA against the passenger seat picture G _PA is performed, the operation is invalidated. As a result, erroneous operation can be reliably prevented.

In the display device (3) according to the present invention, in the display device (1) or (2), the display means can provide individual information for each viewing direction on the driver seat side and the passenger seat side. When the display is switched to the separated display, the viewing direction on either the driver seat side or the passenger seat side is set to the specific viewing direction.

According to the display device (3), when the display means is switched to the separate display for displaying individual information for each viewing direction on the driver seat side and the passenger seat side , the driver seat The viewing direction on the side or the passenger seat side is set to the specific viewing direction. That is, when switching to the separated display by the display means, the video (information) displayed for the viewing direction on either the driver seat side or the passenger seat side is set as the priority video. Become. Therefore, when the display unit is switched to the separated display, the user can easily grasp which of the priority images (information) is set.

In the display device (4) according to the present invention, in the display device (1) or (2), the switching unit is based on importance of individual information displayed for each viewing direction. The viewing direction in which high information is displayed is switched to the specific viewing direction.

According to the display device (4), the viewing direction in which highly important information is displayed is set as the specific viewing direction. That is, operations with high importance can be validated and operations with low importance can be invalidated.
For example, when the passenger seat picture G _PA is higher importance than the image for the driver's seat G _DR, operation area on the display screen for the image for the driver's seat G _DR, and a display screen for the front passenger seat picture G _PA When the operation switch arranged so that the operation area in the vehicle overlaps, only the operation input corresponding to the passenger seat image _GPA is valid, and the operation input corresponding to the driver seat image _GDR Is invalid. Therefore, it is possible to validate the operation control for an image that requires more user operation.

The display device according to the present invention (5), in any one of the display device (1) to (4), said limitation means, said a particular viewing direction is displayed against a different viewing direction It is characterized in that the information to be deleted is erased from the screen.

According to the display device (5), information displayed for a viewing direction different from the specific viewing direction (that is, a viewing direction in which the operation input is not accepted) is not displayed on the screen. The user can easily grasp whether or not the information (video) displayed for him / her is priority information (video). Thereby, since an erroneous operation can be prevented more reliably, operation control desired by the user can be realized.

Further, in the display device (6) according to the present invention, in any one of the display devices (1) to (4), the limiting unit individually displays a viewing direction different from the specific viewing direction. The operation-related image for the operation input to be performed is erased from the screen.

According to the display device (6), operation-related images for individual operation inputs displayed in a viewing direction different from the specific viewing direction (that is, a viewing direction in which the operation input is not accepted). Is not displayed on the screen, the user can easily grasp whether or not the information (video) displayed to him / her is priority information (video). Thereby, since an erroneous operation can be prevented more reliably, operation control desired by the user can be realized. The operation-related images are provided, for example, around the operation switches 43 _DR to 49 _DR and 43 _PA to 49 _PA as shown in FIG. 12, or around the display unit 4 as shown in FIG. Key display images 211a to 211g and 212a to 212g for explaining the functions of the operation switches 15a to 15g are listed.

Further, the display device (7) according to the present invention is a vehicle obtained from any of the display devices (1) to (6), intention display information for performing an operation from the user, or a device mounted on the vehicle. When it is determined that a condition for setting a certain viewing direction to the specific viewing direction is established based on environmental information, the switching unit switches the certain viewing direction to the specific viewing direction for a predetermined period. The predetermined period includes a period until the next operation is performed, a period until a predetermined time elapses, a time until the operation is not performed exceeds a predetermined time, and a new period One of the periods until the viewing direction is set to the specific viewing direction is included .

According to the display device (7) , a certain viewing direction is set to the specific viewing direction based on intention display information for performing an operation from the user or vehicle environment information acquired from a device mounted on the vehicle. When the condition is satisfied, the certain viewing direction is switched to the specific viewing direction for the predetermined period. For example, if the condition is established by the user's intention display, when the user wants to perform an operation, the video (information) displayed to the user can be freely displayed as the priority video. (Information) can be set. Further, if the above condition is satisfied depending on the use environment, for example, when further attention to driving the vehicle is required, the passenger seat image _GPA is set as the priority image, and the driver DR It is possible to form a state that cannot be operated.

Hereinafter, embodiments of a display device according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram for explaining a function of the display device according to the embodiment (1) for displaying individual videos on the same screen for a plurality of viewing directions. In the figure, 1 indicates the first image source, and 2 in the figure.
Indicates a second image source. Examples of the image source include a DVD player, a television receiver, and a navigation device.

The first image data D1 obtained from the first image source 1 and the second image data D2 obtained from the second image source 2 are supplied to the display control unit 3. These first
The image data D1 and the second image data D2 are processed so that the display control unit 3 can display them substantially simultaneously on the display unit 4, and the processed display data D3 is supplied to the display unit 4. It has become.

As will be described in detail later, the display unit 4 includes a liquid crystal panel 21 having a parallax barrier 26 as shown in FIG. 3B, and is half the total number of pixels in the horizontal direction (for example, even numbers). Column) is used to display the first display image 5 based on the first image source 1 and the remaining half (e.g.
The odd number column) is used for displaying the second display image 6 based on the second image source 2.

Pixels for the first display image 5 are observers (users) located on the right side of the display unit 4.
Although visible from 7, the pixels for the second display image 6 are blocked by the parallax barrier 26 formed on the surface of the display unit 4 and are not visible to the observer 7. On the other hand, the second
The pixels for the display image 6 are visible to an observer (user) 8 located on the left side of the display unit 4, but the pixels for the first display image 5 are formed on the surface of the display unit 4. It is blocked by the parallax barrier 26 so that it cannot be seen by the observer 8.

As described above, according to the positional relationship with the display unit 4, in other words, according to the viewing angle with respect to the display unit 4, the second display image 6 is not visible, but the first display image 5 is visible, The first display image 5 cannot be seen, but the second display image 6 can be seen. Therefore, different information and contents can be presented to the left and right observers (users) 7 and 8 on the same screen. Of course, if the first image source 1 and the second image source 2 are the same, the left and right observers 7 and 8 can also see the same display image.

FIG. 2 is a perspective view showing an example when the display device according to the embodiment (1) is mounted on a vehicle. The display unit 4 constituting the display device is disposed in front of the driver's seat 11 and the passenger seat 12 and at a substantially center of a dashboard 14 provided below the windshield 13. Various operations on the display device are performed by the display unit 4. The operation is performed by operating a touch panel formed on the surface, an operation unit 15 provided around the touch panel, or an infrared or wireless remote controller (not shown). In addition, a speaker 17 is disposed at each door 16 of the vehicle, and a sound, a warning sound, or the like linked to the display image is output from the speaker 17.

Thus, for example, only the map image of the navigation device can be seen from the driver seat 11 in the first viewing direction, while the TV reception image or DVD movie can be seen from the passenger seat 12 in the second viewing direction. You can make only the image visible. Accordingly, the driver DR seated in the driver's seat 11 receives driving assistance by car navigation, while the passenger seat 13
Passenger seat passenger PA seated in can enjoy TV and movies.

Moreover, since each display image is displayed using the entire screen (for example, 7 inches) of the display unit 4, the screen size is not reduced as in the conventional multi-window display. That is, for the driver DR and the passenger seat occupant PA, as if the screen is occupied, information and contents can be appropriately presented to the driver DR and the passenger seat occupant PA, respectively.

Next, the configuration of the display unit 4 of the display device according to Embodiment (1) will be described in detail. FIG. 3A is a diagram schematically showing a display state when the display unit 4 is viewed from the front, and FIG.
) Is a cross-sectional view taken along line BB in FIG. The display unit 4 includes a liquid crystal panel 21 and a backlight 30. The liquid crystal panel 21 is disposed slightly isolated from the backlight 30 and has pixels composed of RGB colors (three primary colors).

As the liquid crystal panel 21, for example, a panel having 800 pixels in the horizontal direction and 480 pixels in the vertical direction is employed.

Each pixel of the liquid crystal panel 21 is grouped alternately in the vertical direction to the right side (driver's seat 11) pixel R _P and the left side (passenger seat 12) pixel L _P for display control. . That is, half of the total pixels in the horizontal direction of the liquid crystal panel 21 are used for displaying the first display image 5, and the remaining half of the pixels are used for displaying the second display image 6.

The parallax barriers 26 are provided at predetermined intervals in the horizontal direction (intervals that can regulate the light emission direction from each pixel to either the left or right side), and are formed in a vertical stripe pattern. Parallax barrier 2
By 6, the right side (driver's seat 11) pixels R _P is displayed to the left (driver's seat 12) is interrupted, the display to the right will not be cut off, so visible from the right side of the driver's seat 11 On the other hand, the pixel L _P for the left side (passenger seat 12) is blocked from being displayed on the right side (driver's seat 11), but is not blocked from being displayed on the left side and is visible from the left passenger seat 12. It has become.

That is, when the liquid crystal panel 21 is viewed from the right side, the parallax barrier 26 covers the left side pixel L _P and the right side pixel R _P is visible, while when the liquid crystal panel 21 is viewed from the left side, the parallax barrier 26 is the right side pixel R _{P. P} is covered and the left pixel L _P is visible. When the liquid crystal panel 21 is viewed from near the front, both the right pixel R _P and the left pixel L _P can be seen, so that the first display image 5 and the second display image 6 appear to overlap.

Further, if the display control for each pixel of the liquid crystal panel 21 and the arrangement configuration of the parallax barrier 26 are changed, it is also possible to display different images in three or more directions. Further, the viewing angle may be varied by configuring the parallax barrier 26 with a liquid crystal shutter or the like that can be electrically driven. As for the parallax barrier 26, for example, JP-A-10-123461 and JP-A-1
The configuration disclosed in Japanese Patent No. 1-84131 can be applied.
In addition, the right side pixel R _P and the left side pixel L _P arranged alternately in FIG. 3 have RGB colors, but each group has a single color in the vertical direction such as R column, G column, and B column. It may be configured, or may be configured as a row in which a plurality of RGB are mixed.

S4). In FIG. 12, the border line of the operation switches 43 _{PA to} 48 _{PA and} the border line of the operation switch 49 _PA are thick lines, indicating that the passenger seat video _GDR is set as the priority video. , so that the user can easily recognize that the operation corresponding to the passenger seat picture G _PA is enabled.

Also, the placement operation being switch 15a~15h around the display portion 4 (see FIG. 9), but only one image for the driver's seat G _DR, and that in any of the passenger seat picture G _PA may correspond It may be possible to handle only one of them, or they may be mixed.

Next, the processing operation [1-2] performed by the control unit 100 in the AV navigation system employing the display device according to the embodiment (1) is based on the flowcharts shown in FIGS. 13-1 and 13-2. I will explain. Note that this processing operation [1-2] is performed by the priority video setting switch formed on the display unit 4 by the user when the separated display is performed (that is, when the separated display flag _fSE is 1). 41 _DR , 41 _PA , release switch 42 _DR , 42 _PA , operation switches 43 _DR to 49 _DR , 43 _PA to 49 _PA , operation switches 15 a to 15 h constituting the operation unit 15, etc. is there. However, as described above, in the case where separation display is the basis, as a matter of course, the separation display flag _fSE is not necessary, and the fact that the separation display flag _fSE is 1 is included in the start condition. I can't.

First, it is determined whether or not the priority image setting switch 41 _DR for setting the driver seat image G _DR as the priority image has been operated (step S11), and if it is determined that the priority image setting switch 41 _DR has been operated, Next, it is determined whether or not the driver's seat flag _fDR indicating that the driver's seat video _GDR is set as the priority video is 1 (step S12).

If it is determined that the driver's seat flag _fDR is not 1 (that is, the driver's seat video _GDR is not set as the priority video), then the passenger's seat video _GPA is set as the priority video. It is determined whether or not the passenger seat flag f _PA shown is 1 (step S13). Passenger seat flag f _PA is 1
(That is, the passenger seat video G _PA is set as the priority video), the frame lines of the operation switches 43 _PA to 49 _PA provided in the passenger seat video G _PA are thinned (steps). S14
), The timer t _PA for measuring the time during which the operation for the passenger seat video G _PA is not performed (that is, the time since the last operation) is stopped (step S15), and the passenger seat occupant flag f _{PA is set} to 0. Return (step S16), and then proceed to step S17. On the other hand, if it is determined in step S13 that the passenger seat occupant flag f _PA is not 1, steps S14 to S16 are skipped and the process proceeds to step S17.

Next, the borders of the operation switches 43 _DR to 49 _DR provided in the driver seat image G _DR are thickened (step S 17), and the operation time for the driver seat image G _DR is not performed (that is, the last operation). The timer t _DR for measuring the time from (1) is started with 0 (step S18), the driver's seat flag _fDR is set to 1 (step S19), and then the driver's seat video _GDR becomes the priority video. The user is notified of the setting (step S20). If it is determined in step S12 that the driver's seat flag _fDR is 1 (that is, the driver's seat video _GDR is already set as a priority video), the timer _tDR is reset to 0 (step S21). Then, the processing operation [1-2] is finished as it is. The notification method includes, for example, a method of outputting the sound from the speaker 17 and a method of displaying a notification image. However, the notification may be made by making the above-mentioned operation switch frame thicker.

On the other hand, if it is determined in step S11 that the priority image setting switch _41DR has not been operated, the priority image setting switch 4 for setting the passenger seat image _GPA as the priority image is next.
It is determined whether or not 1 _PA has been operated (step S22), and if it is determined that the priority image setting switch 41 _PA has been operated, it is next determined whether or not the passenger seat flag f _PA is 1 (step S22). S23).

If it is determined that the passenger seat flag f _PA is not 1 (that is, the passenger seat image G _PA is not set as the priority image), it is next determined whether or not the driver seat flag f _DR is 1 ( Step S
24). Driver's flag f _DR is 1 (i.e., the image for the driver's seat G _DR is set to the priority video) When it is judged that the driver's seat of the image G _DR operation switch 43 _DR to 49 provided in the _DR for The frame is narrowed (step S25), the timer _tDR is stopped (step S26), the driver's seat flag _fDR is returned to 0 (step S27), and then the process proceeds to step S28. On the other hand, in step S24, the driver's seat flag f _DR is if not 1 decision, step S25~S27
Skip to step S28.

Next, the operation switches 43 _PA to 49 _PA provided in the passenger seat video G _PA are thickened (step S28), the timer t _{PA is set} to 0 (step S29), and the passenger seat flag f _{PA is started.}
Is set to 1 (step S30), and then the user is notified that the passenger seat video _GPA has been set as the priority video (step S31). If it is determined in step S23 that the passenger seat flag f _PA is 1 (that is, the passenger seat video G _PA is already set as the priority video), the timer t _PA is reset to 0 (step S32). Then, the processing operation [1-2] is finished as it is. The notification method includes, for example, a method of outputting the sound from the speaker 17 and a method of displaying a notification image. However, the notification may be made by making the above-mentioned operation switch frame thicker.

On the other hand, if it is determined in step S22 that the priority video setting switch 41 _PA has not been operated (that is, neither the priority video setting switch 41 _DR or 41 _PA has been operated), step S41 (FIG. 13-2). Then, it is determined which operation other than the priority video setting switches 41 _DR and 41 _PA has been performed.

Operation area on the display screen for the image for the driver's seat G _DR, and operation switches the operation area on the display screen for the passenger seat picture G _PA is arranged so as to overlap (overlap switch (e.g., an operation switch 43 if _{DR ~48 DR, 43 PA ~48 PA} )) determined that has been operated, then the driver's seat flag f _DR is determined whether or not 1 (step S42), the driver's seat flag f _DR
Is 1 (that is, the driver's seat video _GDR is set as the priority video)
To the video G _DR for the driver's seat, do control in accordance with the operation (step S43), then returns the timer t _DR to 0 (step S44).

On the other hand, if the driver's seat flag f _DR is not 1 determines, then it is determined whether the passenger seat flag f _PA is 1 (step S45), 1 is the front passenger's seat flag f _PA (i.e., When it is judged that the passenger seat picture G _PA is set to the priority video), to the video G _PA passenger, do control in accordance with the operation (step S46), then the timer t _PA 0 Return (step S47). If it is determined that the passenger seat flag f _PA is not 1, the operation is regarded as an erroneous operation,
The processing operation [1-2] is finished as it is.

In step S41, it is determined that an operation switch (for example, the operation switch _49DR , except for the priority image setting switch _41DR and the release switch _42DR ) that accepts only an operation input for the driver seat image _GDR is operated. Next, it is determined whether or not the driver seat flag _fDR is 1 (step S48), and the driver seat flag _fDR is 1 (that is, the driver seat video _GDR is set as the priority video). If it is determined, the operation control according to the operation is performed (step S49), and then the timer _tDR is reset to 0 (step S50). On the other hand, if it is determined that the driver's seat flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [1
-2].

If it is determined in step S41 that an operation switch that accepts only an operation input to the passenger seat video G _PA (for example, the operation switch 49 _PA , except for the priority video setting switch 41 _PA and the release switch 42 _PA ) is operated, Next, it is determined whether or not the passenger seat flag f _PA is 1 (step S51), and the passenger seat flag f _PA is 1 (that is, the passenger seat video G).
If it is determined that _PA is set as the priority video, operation control according to the operation is performed (step S52), and then the timer t _PA is returned to 0 (step S53). On the other hand, if it is determined that the passenger seat flag f _PA is not 1, the operation is regarded as an erroneous operation, and the processing operation [1-2] is performed as it is.
Exit.

If it is determined in step S41 that the release switch 42 _DR provided in the driver's seat video _GDR for releasing the separated display is operated, it is next determined whether or not the driver's seat flag _fDR is 1. If it is determined (step S54) and it is determined that the driver's seat flag _fDR is 1, the priority image setting switches _41DR and _41PA and the release switches _42DR and _42PA are deleted from the screen (step S55). Of the two images, the driver seat image _GDR is erased, the passenger seat image _GPA is displayed in full screen (step S56), the timers _tDR and _tPA are stopped (step S57), and the driver seat flag f _DR , the passenger seat flag f _PA is returned to 0 (step S58), and then the separation display flag f _SE is returned to 0 (step S59). On the other hand, if it is determined that the driver's seat flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [1-2] is ended as it is.

If it is determined in step S41 that the release switch 42 _PA for releasing the separate display provided in the passenger seat video G _PA has been operated, it is next determined whether or not the passenger seat flag f _PA is 1. If it is determined (step S60) and it is determined that the passenger seat flag f _PA is 1, the priority image setting switches 41 _DR and 41 _PA and the release switches 42 _DR and 42 _PA are deleted from the screen (step S61). Of the two images, the passenger seat image _GPA is erased and the driver seat image _GDR is displayed on the full screen (step S62), and then the process proceeds to step S57.

Next, a processing operation [1-3] performed by the control unit 100 in the AV navigation system in which the display device according to the embodiment (1) is employed will be described based on the flowchart shown in FIG. The processing operation [1-3] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1). However, as described above, in the case where separation display is the basis, as a matter of course, the separation display flag _fSE is not necessary, and the fact that the separation display flag _fSE is 1 is included in the start condition. I can't.

First, it is determined whether or not the driver's seat flag _fDR is 1 (step S71). If it is determined that the driver's seat flag _fDR is 1, then the timer _tDR is set to a predetermined time T (for example, 10 seconds) or longer (step S72), and if it is determined that the timer _tDR is longer than the predetermined time T (that is, 10 seconds have passed since the last operation). Driver's seat video G _DR
The operation switches 43 _DR to 49 _DR provided in the frame are thinned (step S73), and the timer t
The _DR is stopped (step S74), it returns the driver flag f _DR to 0 (step S75). On the other hand, if it is determined that the timer _tDR is not equal to or longer than the predetermined time T, the processing operation [1-3] is terminated as it is.

Further, in step S71, if the driver's seat flag f _DR is not 1 determines, then the passenger seat flag f _PA is judged whether or not 1 (step S76), in the passenger seat flag f _PA 1 If it is determined that the timer t _PA is equal to or longer than the predetermined time T (step S77), the timer t _PA is equal to or longer than the predetermined time T (that is, the last operation is performed). if it is determined that we have elapsed 10 seconds), operation switch 43 provided in the video G _PA passenger
_PA to 49 _PA are thinned (step S78), and the timer t _PA is stopped (step S79).
), The passenger seat flag f _PA is reset to 0 (step S80). On the other hand, the timer t _PA has a predetermined time T
When it is determined that it is not above, or when it is determined that the passenger seat flag f _PA is not 1, the processing operation [1-3] is terminated as it is.

According to the AV navigation system in which the display device according to the embodiment (1) is adopted, the operation area on the display screen for the driver seat video _GDR and the display screen for the passenger seat video _GPA are displayed. Operation switches (eg, FIG. 1) arranged so that their operation areas overlap.
1. When an operation is performed on the operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA shown in FIG. 12 (operating switches arranged in the same area E _{7 to} E ₁₂ ), the driver's seat for priority images of the use video G _DR and the passenger seat picture G _PA, operation control in accordance with the operation is performed. That is, no operation control is performed on a video other than the priority video.

For example, when the passenger seat video G _PA is set as the priority video, the operation area on the display screen for the driver seat video G _DR and the operation area on the display screen for the passenger seat video G _PA are: When operation is performed on overlapping operation switches, the passenger seat video G _PA
Only the operation for is enabled, and the operation for the driver's seat video _GDR is disabled. Therefore, the user can realize desired operation control by appropriately setting and switching the priority video, or by accurately recognizing which priority video is set.

As described above, the operation area on the display screen for the driver's seat video _GDR and the passenger's seat video G
_{Even when the} operation switch arranged so that the operation areas on the display screen for the _PA overlap each other, the operation control desired by the user can be realized. In other words, since operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA shown in FIGS. 11 and 12 can be provided with operation switches having different properties in the same region E _{7 to} E ₁₂ . The display screen can be used more effectively.

In the display device according to the embodiment (1), is disposed priority images setting switch 41 _DR in the region E _1, priority images setting switch 41 _PA is arranged in the region E ₄ which does not overlap the region E ₁ disposed release switch 42 _DR is the described, also in the area E ₂ for the case to be, have described the case where the arranged release switch 42 _PA in the region E ₅ which does not overlap the region E _2, these The arrangement of the switch is not limited to this. In another embodiment, for example, the priority picture setting switch 41 _PA is arranged in the area E ₁ where the priority picture setting switch 41 _DR is arranged, or the release switch is arranged. 42 _DR may be arranged to release switch 42 _PA in the region E ₂ are disposed.

Next, an AV navigation system using the display device according to the embodiment (2) will be described. However, the AV navigation system is the same as that shown in FIG.
Since the configuration is the same as that of the AV navigation system shown in FIG. 1, the control unit is given a different reference numeral, and the other description is omitted here.

The processing operation [2-1] performed by the control unit 100A in the AV navigation system in which the display device according to the embodiment (2) is employed will be described based on the flowchart shown in FIG. This processing operation [2-1] is a separate display (multi-view) for allowing the driver _DR to visually _{recognize the} driver's seat image _GDR and allowing the passenger seat passenger _PA to visually recognize the passenger's seat image GPA. Is an operation performed when a user gives an instruction by operating the operation switch, the operation unit 15, the remote control 123, or the like formed on the display unit 4.

In addition, when the separated display is basic (that is, when the separated display is performed after the AV navigation system is turned on), there is no need for a separate display instruction from the user, and the processing operation described below [2-1] is not required, it is not necessary for separating display flag f _SE for indicating that the separation display is being performed.

When separation display is instructed by the user, first, as shown in FIG. 15, one of the two images is displayed as a driver seat image _GDR based on a predetermined condition, and the rest is displayed on the passenger seat. Video G
Display as _PA (step S201), then the upper right of the image for the driver's seat G _DR, to form a preferential video setting switch 41 _DR for setting the image for the driver's seat G _DR priority video, passenger in the upper left of the picture G _PA, to form a preferential video setting switch 41 _PA for setting the passenger seat picture G _PA in priority images (step S202). 16 (a) is a view showing an example of the image for the driver's seat G _DR, FIG. 16 (b) is a diagram showing an example of a passenger seat picture G _PA.

Next, release switches 42 _DR and 42 _PA for releasing the separation display are displayed on the driver seat video G _DR.
, Formed in each picture G _PA passenger (step S203), then the 1 separate display flag f _SE for indicating that the separation display is performed (step S204). Then, the right side (i.e., the driver's seat side) display the arrows 50R pointing to (step S205), it sets the driver's seat flag f _DR 1, a passenger seat flag f _PA to 0 (step S206, S2
07). In FIG. 16, an arrow 50R pointing to the right side is displayed, indicating that the driver's seat video _GDR is set as the priority video, and that the driver's seat video _GDR can be operated. The user can easily recognize it. Also, passenger seat video G _PA
When the priority image is set, as shown in FIG. 17, an arrow 50L pointing to the left side (that is, the passenger seat side) is displayed.

Next, the processing operation [2-2] performed by the control unit 100A in the AV navigation system employing the display device according to the embodiment (2) is based on the flowcharts shown in FIGS. 18-1 and 18-2. I will explain. This processing operation [2-2] is performed by the user when the separation display is performed (that is, when the separation display flag _fSE is 1).
Priority video setting switches 41 _DR and 41 _PA , release switches 42 _DR and 42 _PA , operation switches 43 _DR to 49 _DR , 43 _PA to 49 _PA , and operation switches 15 a to 15 h constituting the operation unit 15 are operated. This is the operation performed when However, as described above, in the case where separation display is the basis, as a matter of course, the separation display flag _fSE is not necessary, and the fact that the separation display flag _fSE is 1 is included in the start condition. I can't.

First, it is determined whether or not the priority image setting switch 41 _DR for setting the driver seat image G _DR as the priority image is operated (step S211), and if it is determined that the priority image setting switch 41 _DR is operated, Next, it is determined whether or not the driver's seat flag _fDR indicating that the driver's seat video _GDR is set as the priority video is 1 (step S212).

If it is determined that the driver's seat flag _fDR is not 1 (that is, the driver's seat video _GDR is not set as the priority video), then the passenger's seat video _GPA is set as the priority video. It is determined whether or not the passenger seat flag f _PA shown is 1 (step S213). If it is determined that the passenger seat flag f _PA is 1 (that is, the passenger seat image G _PA is set as the priority image), the arrow 50L pointing to the left side is erased from the screen (step S214), and the passenger seat The timer t _PA for measuring the time during which the operation for the video G _PA is not performed is stopped (step S215),
The passenger seat flag f _PA is returned to 0 (step S216), and then the process proceeds to step S217.
On the other hand, if it is determined in step S213 that the passenger seat flag f _PA is not 1, steps S214 to S216 are skipped and the process proceeds to step S217 as it is.

Then, to display the arrows 50R pointing to the right (step S217), sets the driver's seat flag f _DR 1 (step S218), then use that image for the driver's seat G _DR is set to the priority video's (Step S219). If it is determined in step S212 that the driver's seat flag _fDR is 1 (that is, the driver's seat video _GDR is already set as a priority video), the processing operation [2-2] is terminated as it is. . As a notification method, for example,
There are a method of outputting the sound from the speaker 17 and a method of displaying a notification image, but the above-described arrow display may be used as the notification.

On the other hand, if it is determined in step S211 that the priority image setting switch _41DR has not been operated, then whether or not the priority image setting switch 41 _PA for setting the passenger seat image _GPA as the priority image has been operated. (Step S220), the priority video setting switch 41 _PA
If it is determined that the passenger seat flag f _PA has been operated, it is next determined whether or not the passenger seat flag f _PA is 1 (step S221).

If it is determined that the passenger seat flag f _PA is not 1 (that is, the passenger seat image G _PA is not set as the priority image), it is next determined whether or not the driver seat flag f _DR is 1 ( Step S
222). If it is determined that the driver seat flag _fDR is 1 (that is, the driver seat video _GDR is set as the priority video), the arrow 50R pointing to the right side is erased from the screen (step S22).
3) _Return the driver's seat flag _fDR to 0 (step S224), and then proceed to step S225. On the other hand, if it is determined in step S222 that the driver's seat flag _fDR is not 1, steps S223 and S224 are skipped and the process proceeds directly to step S225.

Next, an arrow 50L pointing to the left is displayed (step S225), the timer t _{PA is set} to 0 and started (step S226), the passenger seat flag f _PA is set to 1 (step S227), and then the passenger seat is used. The user is notified that the video _GPA has been set as the priority video (step S2).
28). If it is determined in step S221 that the passenger seat flag f _PA is 1 (that is, the passenger seat video G _PA has already been set to the priority video), the timer t _PA is reset to 0 (step S229). Then, the processing operation [2-2] is finished as it is. Note that examples of the notification method include a method of outputting sound from the speaker 17 and a method of displaying a notification image, but the above-described arrow display may be used as the notification.

On the other hand, in step S220, the priority video setting switch 41 _PA is not operated (
That is, if it is determined that neither of the priority video setting switches 41 _DR and 41 _PA is operated), the process proceeds to step S231 (FIG. 18-2) and the priority video setting switches 41 _DR and 41 _PA are operated.
It is determined which operation has been performed.

Operation area on the display screen for the image for the driver's seat G _DR, and operation switches the operation area on the display screen for the passenger seat picture G _PA is arranged so as to overlap (overlap switch (e.g., an operation switch 43 if _{DR ~48 DR, 43 PA ~48 PA} )) determined that has been operated, then the driver's seat flag f _DR is determined whether or not 1 (step S232), the driver's seat flag f _DR 1 it is (i.e., the image for the driver's seat G _DR is set to priority images) if it is determined that, for the video G _DR for the driver's seat performs an operation control corresponding to the operation (step S233).

On the other hand, if the driver's seat flag f _DR is not 1 determines, then it is determined whether the passenger seat flag f _PA is 1 (step S234), 1 is the front passenger's seat flag f _PA (i.e., When it is judged that the passenger seat picture G _PA is set to the priority video), to the video G _PA passenger, do control in accordance with the operation (step S235), then the timer t _PA 0 return(
Step S236). If it is determined that the passenger seat flag f _PA is not 1, the operation is regarded as an erroneous operation, and the processing operation [2-2] is terminated as it is.

Further, in step S231, the operation switch for accepting only operation input to the image for the driver's seat G _DR (e.g., an operation switch 49 _DR, however, priority images setting switch 41 _DR, excluding the release switch 42 _DR) it is judged that has been operated Next, it is determined whether or not the driver seat flag _fDR is 1 (step S237), and the driver seat flag _fDR is 1 (that is, the driver seat video _GDR is set as the priority video). If it is determined, the operation control according to the operation is performed (step S238). On the other hand, if it is determined that the driver's seat flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [2-2] is terminated as it is.

If it is determined in step S231 that an operation switch that accepts only an operation input to the passenger seat video G _PA (for example, the operation switch 49 _PA , except for the priority video setting switch 41 _PA and the release switch 42 _PA ) is operated, Next, it is determined whether or not the passenger seat flag f _PA is 1 (step S239), and the passenger seat flag f _PA is 1 (that is, the passenger seat video G _PA is set as the priority video). If it is determined, the operation control according to the operation is performed (
Thereafter, the timer t _PA is returned to 0 (step S241). On the other hand, if it is determined that the passenger seat flag f _PA is not 1, the operation is regarded as an erroneous operation and the processing operation [
2-2] is terminated.

In step S231, provided the image for the driver's seat G _DR, it is judged that the release switch 42 _DR for releasing the separated display is operated, then the driver's seat flag f _DR is whether or not 1 determining (step S242), it is judged that the driver's seat flag f _DR is 1, erased preferentially or video setting switch 41 _DR, 41 _PA, a release switch 42 _DR, 42 _PA from the screen (step S243), The arrow 50R or the arrow 50L is erased from the screen (step S244).
Of the two images, the driver seat image _GDR is deleted and the passenger seat image _GPA is displayed in full screen (
Step S245), the timer t _PA is stopped (Step S246), the driver's seat flag f _DR ,
The passenger seat flag f _PA is returned to 0 (step S247), and then the separation display flag f _SE is returned to 0 (step S248). On the other hand, if it is determined that the driver's seat flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [2-2] is terminated as it is.

If it is determined in step S231 that the release switch 42 _PA provided in the passenger seat video G _PA for releasing the separation display has been operated, it is next determined whether or not the passenger seat flag f _PA is 1. If it is determined (step S249) and it is determined that the passenger seat flag f _PA is 1, the priority image setting switches 41 _DR and 41 _PA and the release switches 42 _DR and 42 _PA are erased from the screen (step S250). The arrow 50R or the arrow 50L is deleted from the screen (step S251).
Of the two images, the passenger seat image _GPA is erased and the driver seat image _GDR is displayed in full screen (
Step S252), and then the process proceeds to Step S246.

Next, the processing operation [2-3] performed by the control unit 100A in the AV navigation system in which the display device according to the embodiment (2) is employed will be described based on the flowchart shown in FIG. The processing operation [2-3] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, the driver's seat flag f _DR is determined whether or not 1 (step S261), it is judged that the driver's seat flag f _DR is 1, and ends the processing operation [2-3]. On the other hand, if the driver's seat flag f _DR is not 1 determines, then the passenger seat flag f _PA is judged whether or not 1 (step S262), the passenger seat flag f _PA is is judged to be 1 if, then, the timer t _PA is determined whether more than a predetermined time T (step S263), the timer t _PA is equal to or more than the predetermined time T (i.e., since the last operation is performed 6 Seconds))
The left arrow 50L is erased from the screen (step S264), the timer t _PA is stopped (step S265), and the passenger seat flag f _PA is returned to 0 (step S266).

Thereafter, an arrow 50R pointing to the right side is displayed (step S267), and the driver's seat flag _{fDR is set} to 1.
(Step S268). On the other hand, if it is determined in step S263 that the timer t _PA is not equal to or greater than the predetermined time T, or if it is determined in step S262 that the passenger seat flag f _PA is not 1, the processing operation [2-3] is terminated. To do.

According to the AV navigation system in which the display device according to the above embodiment (2) is employed, any one of the driver seat video _GDR and the passenger seat video _GPA is always displayed while being displayed separately. Priority video can be set. Here, the driver's seat video _GDR is set as the priority video in the normal state. However, in another embodiment, the driver's seat video _GDR is not the driver's seat video _GDR , but in the normal state, the front passenger seat. The video _GPA may be set as the priority video.

Next, an AV navigation system using the display device according to the embodiment (3) will be described. However, the AV navigation system is the same as that shown in FIG.
Since the configuration is the same as that of the AV navigation system shown in FIG. 1, the control unit is given a different reference numeral, and the other description is omitted here.

FIG. 20 is a diagram showing an external front view of the display device according to Embodiment (3). 20 in the figure
1A shows a display device. The display device 201A includes a display unit 4 having a touch panel 118 formed on the surface thereof, and an operation unit 15A (operation switches 15a to 15h,
And it is configured priority video selector switch 15i for setting the passenger seat picture G _PA) and contain.

A processing operation [3-1] performed by the control unit 100B in the AV navigation system in which the display device according to the embodiment (3) is employed will be described based on the flowchart shown in FIG. This processing operation [3-1] is an operation performed after the AV navigation system is turned on, and is basically separated display.

First, based on a predetermined condition, as shown in FIGS. 22 and 23, one of the two images is displayed as a driver seat image _GDR , and the rest is displayed as a passenger seat image _GPA ( Step S301). Figure 22 (a) is an explanatory view for explaining a pixel to be used for the pixel and the passenger seat picture G _PA used for the image for the driver's seat G _DR, 22 (b) is the driver's seat is a diagram illustrating an example of use the video G _DR, FIG. 22 (c) is a diagram showing an example of a passenger seat picture G _PA. As shown in FIG. 22 (a), an even number column (right pixel R _P ) which is half the total number of pixels in the horizontal direction is used for the driver seat image G _DR , and an odd column (left pixel L _P ) is used. Used in passenger seat video _GPA . FIG. 23A is an enlarged view of an example of the driver seat video _GDR , and FIG.
_These are the figures which expanded and showed an example of image _| video GPA for passenger seats.

Then, to indicate that the priority video is set to the image for the driver's seat G _DR, displays a handle mark 51 in the image of the driver's seat (step S302), sets the driver's seat flag f _DR 1 ( Step S303). In FIG. 23, the handle mark 51 is displayed, indicating that the driver seat video _GDR is set as the priority video, and that the user can operate the driver seat video _GDR . Can be easily recognized.
Further, when the passenger seat video G _PA is set as the priority video (that is, the driver seat video G
_{When DR} is not set as the priority video), as shown in FIG.
A prohibition mark 52 in which “x” mark is superimposed on 1 is displayed.

Next, the processing operation [3-2] performed by the control unit 100B in the AV navigation system in which the display device according to the embodiment (3) is employed will be described based on the flowchart shown in FIG. The processing operation [3-2] is an operation performed every predetermined period.
First, determine which operation has been performed (step S311), the operation area on the display screen for the image for the driver's seat G _DR, and so that the operation area on the display screen for the passenger seat picture G _PA overlap Operation switches (duplicate switches (for example, operation switches 43 _DR to
48 _DR , 43 _{PA to} 48 _PA )), it is next determined whether or not the driver's seat flag f _DR is 1 (step S312).

If it is determined that the driver's seat flag _fDR is 1 (that is, the driver's seat video _GDR is set as the priority video), operation control corresponding to the operation is performed on the driver's seat video _GDR ( Step S313). On the other hand, if it is determined that the driver's seat flag _fDR is not 1 (that is, the passenger seat image _GPA is set as the priority image), operation control is performed on the passenger seat image _GPA according to the operation. (Step S314) After that, the timer t _PA for measuring the time during which the operation for the passenger seat image G _PA is not performed (that is, the time from the last operation) is returned to 0 (Step S315).

If it is determined in step S311 that an operation switch (for example, the operation switch 49 _DR ) that accepts only an operation input for the driver seat image G _DR has been operated, then whether or not the driver seat flag f _DR is 1 is determined. (Step S316), and if it is determined that the driver's seat flag _fDR is 1 (that is, the driver's seat video _GDR is set as the priority video), the operation control corresponding to the operation is performed. (Step S317). On the other hand, if it is determined that the driver's seat flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [3-2] is terminated as it is.

If it is determined in step S311 that an operation switch (for example, the operation switch 49 _PA ) that accepts only an operation input for the passenger seat image G _PA has been operated, then whether or not the driver seat flag f _DR is 0 is determined. Judgment is made (step S318), and the driver's seat flag _fDR is 0 (
That is, if it is determined that the passenger seat image G _PA is set as the priority image), the operation control corresponding to the operation is performed (step S319), and then the timer t _PA is returned to 0 (step S).
320). On the other hand, if it is determined that the driver's seat flag _fDR is not 0, the operation is regarded as an erroneous operation, and the processing operation [3-2] is terminated as it is.

In step S311, the priority image provided around the display unit 4 is converted into the passenger seat image G.
When it is judged that the changeover switch 15i for setting the _PA is operated, then, in order to indicate that the priority images is set on the passenger seat video G _PA, the handle mark 51 in the image of the driver's seat window It erases from the top (step S321), and instead displays a prohibition mark 52 (step S322) and sets the driver's seat flag _fDR to 0 (step S323).

Thereafter, the timer t _{PA is set} to 0 and started (step S324), and the user is notified that the passenger seat video G _PA has been set as the priority video (step S325). The notification method includes, for example, a method of outputting the sound from the speaker 17 and a method of displaying a notification image. The display of the handle mark 51 and the prohibition mark 52 described above may be used as the notification.

Next, the processing operation [3-3] performed by the control unit 100B in the AV navigation system in which the display device according to the embodiment (3) is employed will be described based on the flowchart shown in FIG. This processing operation [3-3] is an operation performed every predetermined period.
First, it is determined whether or not the driver's seat flag _fDR is 1 (step S331). If it is determined that the driver's seat flag _fDR is 1, the processing operation [3-3] is ended as it is.

On the other hand, if it is determined that the driver's seat flag _fDR is not 1 (that is, the passenger seat video G _PA is set as the priority video), then whether or not the timer t _PA is equal to or longer than a predetermined time T is determined. Judgment (
If it is determined in step S332 that the timer t _PA is equal to or longer than the predetermined time T (that is, 6 seconds have passed since the last operation), the prohibition mark 52 is erased from the screen (step S333). ), The handle mark 51 is displayed (step S334).

Thereafter, the timer t _PA stops (step S335), the 1 driver's seat flag f _DR (step S336), the image for the driver's seat G _DR is notified to the user that it has been set to priority images (
Step S337). The notification method includes, for example, a method of outputting the sound from the speaker 17 and a method of displaying a notification image. The display of the handle mark 51 and the prohibition mark 52 described above may be used as the notification.

According to the AV navigation system in which the display device according to the above embodiment (3) is adopted, either the driver seat image _{GDR or the} passenger seat image _GPA can be always set as the priority image. it can. Here, the driver's seat video _GDR is set as the priority video in the normal state. However, in another embodiment, the driver's seat video _GDR is not the driver's seat video _GDR , but in the normal state, the front passenger seat. The video _GPA may be set as the priority video.

Next, an AV navigation system using the display device according to the embodiment (4) will be described. However, the AV navigation system is the same as that shown in FIG.
Since the configuration is the same as that of the AV navigation system shown in FIG. 1, the control unit is given a different reference numeral, and the other description is omitted here.

The control unit 100C performs the processing operation [4-1] similar to the processing operation [1-1] (see FIG. 10) performed by the control unit 100, and displays the pixel as shown in FIG. Figure 1
1 (b) and FIG. 12 (a), the driver's seat video _GDR is displayed, and FIG. 11 (c) and FIG.
And it displays an passenger seat picture G _PA as shown in 2 (b).

Next, the processing operation [4-2] performed by the control unit 100C in the AV navigation system in which the display device according to the embodiment (4) is employed will be described based on the flowchart shown in FIG. The processing operation [4-2] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1). However, as described above, in the case where separation display is the basis, as a matter of course, the separation display flag _fSE is not necessary, and the fact that the separation display flag _fSE is 1 is included in the start condition. I can't.

First, based on the vehicle speed information obtained from the navigation unit 106, it is determined whether the vehicle speed v is equal to or higher than a predetermined speed V (for example, 60 km / h) (step S81), and the vehicle speed v is equal to or higher than the predetermined speed V. (That is, the vehicle is traveling at high speed and the setting condition for setting the passenger seat video G _PA as the priority video is satisfied), then the passenger seat flag f _PA is 1. It is determined whether or not there is (step S82). The vehicle speed information may be acquired directly from the vehicle speed sensor.

If it is determined that the passenger seat flag f _PA is not 1 (that is, the passenger seat video G _PA is not set as the priority video), the process proceeds to step S83 to set the passenger seat video G _PA as the priority video. Perform the process. The processing operations in steps S83 to S90 are the same as the processing operations in steps S24 to S31 shown in FIG.

After the process of step S90, the setting condition satisfaction flag F _PA for indicating that the setting condition for setting the passenger seat image _GPA as the priority image is satisfied is set to 1 (step S91). In step S82, the passenger seat flag f _PA is 1 (that is, the passenger seat image G
If it is determined that _PA is already set as a priority image), the process proceeds to step S91, where the setting condition establishment flag F _PA is set to 1.

If it is determined in step S81 that the vehicle speed v is not equal to or higher than the predetermined speed V, it is next determined whether or not the setting condition establishment flag F _PA is 1 (step S92), and the setting condition establishment flag F _{PA is determined.} Is determined to be 1, the vehicle speed v is determined to be a predetermined speed (V−α based on the vehicle speed information.
It is determined whether or not the following is true (step S93). The numerical value α is a positive number and serves as a buffer region.

If it is determined that the vehicle speed v is equal to or lower than a predetermined speed (V−α) (that is, the setting condition for setting the passenger seat image G _PA as the priority image is not satisfied), the setting condition establishment flag F _{PA is} satisfied. 0
(Step S94). On the other hand, if it is determined that the vehicle speed v is not less than or equal to the predetermined speed (V−α), the processing operation [4-2] is terminated as it is. Also, if it is determined in step S92 that the setting condition satisfaction flag F _PA is not 1, the processing operation [4-2] is ended as it is.

Next, the processing operation [4-3] performed by the control unit 100C in the AV navigation system in which the display device according to the embodiment (4) is employed will be described based on the flowchart shown in FIG. The processing operation [4-3] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, based on the on / off information of the parking brake obtained from the navigation unit 106, it is determined whether or not the parking brake is on (step S101), and the parking brake is on (that is, the vehicle is stopped). State, driver's seat video G
If it is determined that the setting condition for setting _DR as a priority image is satisfied, it is then determined whether or not the driver's seat flag _fDR is 1 (step S102). The parking brake on / off information may be acquired directly from a sensor that detects the operating state of the parking brake.

If it is determined that the driver's seat flag _fDR is not 1 (that is, the driver's seat video _GDR is not set as a priority video), the process proceeds to step S103 to set the driver's seat video _GDR as a priority video. Perform the process. Note that the processing operations of steps S103 to S110 are the same as the processing operations of steps S13 to S20 shown in FIG.

After the process of step S110, the setting condition establishment flag _FDR for indicating that the setting condition for setting the driver seat image _GDR as the priority image is satisfied is set to 1 (step S111).
. If it is determined in step S102 that the driver's seat flag _fDR is 1 (that is, the driver's seat video _GDR is already set as a priority video), the process proceeds to step S111.
Set condition satisfaction flag _fDR is set to 1.

In step S101, the parking brake is not on (that is,
If it is determined that the setting condition for setting the driver seat image _GDR as the priority image has not been established), it is then determined whether or not the setting condition establishment flag _FDR is 1 (step S112). If it is determined that the setting condition satisfaction flag _FDR is 1, the setting condition satisfaction flag _FDR is returned to 0 (step S113). On the other hand, if it is determined that the setting condition satisfaction flag _FDR is not 1, the processing operation [4-3] is terminated as it is.

Next, the processing operation [4-4] performed by the control unit 100C in the AV navigation system in which the display device according to the embodiment (4) is employed will be described based on the flowchart shown in FIG. Note that this processing operation [4-4] is a priority video setting switch formed on the display unit 4 by the user when the separation display is performed (that is, when the separation display flag _fSE is 1). 41 _DR , 41 _PA and release switch 42 _DR , 42 _PA and operation switch 43 _DR

On the other hand, in step S124, the priority video setting switch 41 _PA is not operated (
That is, if it is determined that neither of the priority video setting switches 41 _DR and 41 _PA is operated), the process proceeds to step S41 (FIG. 13-2), and any operation other than the priority video setting switches 41 _DR and 41 _PA is performed. Determine if it was done. The description of the processing operation after step S41 is as follows.
It is omitted here.

Further, the control unit 100C performs a processing operation [4-5] similar to the processing operation [1-3] (see FIG. 14) performed by the control unit 100. However, the processing operation [4-5]
This operation is performed every predetermined period when the separated display is being performed (that is, when the separated display flag _fSE is 1) and the setting condition establishment flags F _DR and F _PA are not 1.

According to the AV navigation system in which the display device according to the above embodiment (4) is employed, the setting for setting one of the driver seat video _GDR and the passenger seat video _GPA as the priority video. While the condition is satisfied, the corresponding video out of the both videos is set as the priority video. Thus, for example, when more attention is required for driving the vehicle, the passenger seat image _GPA is set as a priority image, and a state in which the operation of the driver DR cannot be performed is formed. Can be increased.

Next, an AV navigation system using the display device according to the embodiment (5) will be described. However, the AV navigation system is the same as that shown in FIG.
Since the configuration is the same as that of the AV navigation system shown in FIG. 1, the control unit is given a different reference numeral, and the other description is omitted here.

The control unit 100D performs processing operations [1-1] to [1-3] (FIG. 1) performed by the control unit 100.
0, 13 and 14), the same processing operations [5-1] to [5-3] are performed as shown in FIG.

Next, a processing operation [5-4] performed by the control unit 100D in the AV navigation system in which the display device according to the embodiment (5) is employed will be described based on the flowchart shown in FIG. This processing operation [5-4] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1). However, as described above, in the case where separation display is the basis, as a matter of course, the separation display flag _fSE is not necessary, and the fact that the separation display flag _fSE is 1 is included in the start condition. I can't.

First, it is determined whether the traffic jam encounter information or the destination approach information obtained from the navigation unit 106 is received (steps S131 and S132), and the traffic jam encounter information or the destination approach information is received (ie, the destination). When it is judged that the map image is important image) for the guidance to, then, it is determined whether the map image is the image for the driver's seat G _DR (step S133)
.

If it is determined that the map image is the image for the driver's seat G _DR, the program proceeds to step S134, performs processing for setting the image for the driver's seat G _DR priority video. Note that the processing operation in step S134 is the same as the processing operation in steps S12 to S21 shown in FIG.

On the other hand, the map image is not the driver seat image _GDR (that is, the passenger seat image _GPA ).
If it is determined, the process proceeds to step S135, and processing for setting the passenger seat video _GPA as the priority video is performed. The processing operation in step S135 is the same as that in step S2 shown in FIG.
Since this is the same as the processing operation of 3 to S32, the description thereof is omitted here.

If it is determined in steps S131 and S132 that neither the traffic jam encounter information nor the destination approach information has been received, then whether or not the CD playback end information obtained from the CD / MD playback unit 101 has been received. (Step S136) and the CD playback end information is received (
That is, if it is determined that the reproduction status image showing the CD reproduction state is important video), then, it is determined whether reproduction status image is a image for the driver's seat G _DR (step S137).

If it is determined that the reproduction state image is the image for the driver's seat G _DR, the program proceeds to step S138, performs processing for setting the image for the driver's seat G _DR priority video. Meanwhile, the reproduction state image is not the image for the driver's seat G _DR (i.e., passenger seat is a picture G _PA) When it is judged that, the process proceeds to step S139, for setting the passenger seat picture G _PA preferentially video Perform the process. If it is determined in step S136 that the CD playback end information has not been received, the processing operation [5-4] is ended as it is.

According to the AV navigation system in which the display device according to the embodiment (5) is adopted, an operation that can handle both the map video from the navigation unit 106 and the playback status video in the CD / MD playback unit 101. switch (e.g., FIG. 11, as the operation switch _{43 DR ~48 DR, 43 PA ~48} PA shown in FIG. 12, the same region E ₇ to E arranged operated switch ₁₂₎ operation to have been performed In this case, operation control corresponding to the operation is performed on an important video (for example, a video with a high possibility of being operated) of the map video and the reproduction status video. That is, no operation control is performed on the non-important video.

For example, when the playback status video displayed as the passenger seat video G _PA is set as the important video, the operation area on the display screen for the driver seat video G _DR and the passenger seat video G _PA are displayed. When the operation switch arranged so that the operation areas on the display screen overlap with each other, only the operation for the passenger seat image _GPA is effective, and the driver seat image G
Operations on _DR are invalid. Therefore, it is possible to validate the operation control for an image that requires more user operation.

In the display devices according to the above embodiments (1) to (5), intention display information and vehicle environment information (for example, vehicle speed information, parking brake on / off information, traffic jam encounter information, traveling) By setting the priority video and important video as a trigger using the road type information (general road, highway, etc.)) in the middle as a trigger, appropriate operation control desired by the user is realized. In the embodiment, the priority video may be switched every predetermined period. For example, the priority video is switched in the order of the driver seat video G _DR , the passenger seat video G _PA , the driver seat video G _DR , and the passenger seat video G _PA every predetermined period. Thereby, simplification of operation can be achieved. In addition, since the processing is simplified, the processing load can be reduced.

In addition, as said predetermined period, the following ac are mentioned, for example.
a) A period until a certain period (for example, 20 seconds) elapses.
b) A period until a time when no operation is performed exceeds a predetermined time (for example, 10 seconds).
c) A period until switching of the priority video is instructed by another trigger (for example, an operation by a user).

In another embodiment, when switching the priority video, a period (for example, 3 seconds) in which neither of them is set as the priority video may be provided. For example, when the priority image is switched from the image for the driver's seat G _DR in the passenger seat video G _PA, rather than switched immediately, since the period that no reception operations from either of the two images will be provided,
It is possible to prevent an operation performed simultaneously with the switching from being an erroneous operation.

In the display devices according to the above embodiments (1) to (5), the thickness of the operation switch frame line is changed (see FIG. 12), the arrow 50R pointing to the right side, or the arrow 50L pointing to the left side is displayed. (
16 and FIG. 17), a handle mark 51 reflecting the driver's seat, or a prohibition mark 52
Is displayed (see FIG. 23 and FIG. 24) to notify the user of which priority video is set. However, in another embodiment, only the priority video is individually displayed. The information may be displayed. For example, when the driver seat video _GDR is set as the priority video, only the driver seat video _GDR is displayed on the display unit 4 and the passenger seat video _GPA is not displayed on the display unit 4.

In another embodiment, an operation-related image for operation input may be displayed only for a video set as a priority video. For example, if the image for the driver's seat G _DR is set to priority images, as shown in FIG. 31, but displays the operation switch 43 _DR to 48 _DR accepting an operation input to the image for the driver's seat G _DR, a passenger The operation switches 43 _{PA to} 48 _PA for receiving an operation input for the seat video G _PA are not displayed.

The operation-related images include key display images 211a to 211g for explaining the functions of the operation switches 15a to 15g provided around the display unit 4 as shown in FIG.
212a~212g and the like, for example, if the image for the driver's seat G _DR is set to priority images, as shown in FIG. 33, key display image for the image for the driver's seat G _DR 211a~2
To display the 11g, but you do not want to see the key display image 212a~212b for the passenger's seat for the video G _PA.

In still another embodiment, an operation-related image for operation input for a priority video may be displayed without being limited to the priority video. For example, if the image for the driver's seat G _DR is set to priority images, as shown in FIG. 31, the operation switch 43 _DR to 49 _DR for the image for the driver's seat G _DR, only the image for the driver's seat G _DR without, even so as to display the video G _PA for the passenger's seat.

In the display devices according to the above embodiments (1), (2), (4), and (5), the priority image setting switch 41 _DR for setting the driver seat image _GDR as the priority image, the assistant Although the priority video setting switch 41 _PA for setting the seat video G _PA as the priority video is provided, in another embodiment, the two states are alternately switched every time the same operation is performed. A toggle switch that can be used may be provided.
