The imaging areas of the side cameras 14L and 14R are partially overlapped with the imaging area of the rear camera 14A, and the range from the right diagonal rear to the left diagonal rear of the vehicle 12 is determined by the rear camera 14A and the side cameras 14L and 14R. Wide-angle imaging is possible.

  Although the side cameras 14L and 14R are provided on the door mirrors 16L and 16R, the side cameras 14L and 14L may be provided instead of the door mirrors 16L and 16R. In this case, a camera mounting portion may be provided on the side door (front side door) in place of the door mirrors 16L and 16R. The camera mounting portion is not limited to the front side door, and the front fender of the vehicle, the roof of the vehicle, and the center pillar. It may be provided on the side of the vehicle body.

  The vehicular visual recognition device 10 is provided with a display control device 18 and a monitor 20 as an operation display unit. The display control device 18 controls the operation of the monitor 20 and controls the camera 14 (rear camera 14A, side camera). 14L, 14R) are displayed on the monitor 20.

  The monitor 20 is provided with a display unit 22 as a display unit and a touch panel unit 24 as a touch operation unit. The monitor 20 is a touch panel display using the display unit 22 and the touch panel unit 24. The display unit 22 and the touch panel unit 24 are formed in a rectangular thin plate shape that is long in one direction, and the touch panel unit 24 is overlaid on the display surface side of the display unit 22.

  The display unit 22 uses an LCD (a liquid crystal display or an organic EL) as a thin display medium, and an image can be displayed on the display surface by operating with the backlight turned on. In the touch panel unit 24, a plurality of transparent electrodes (not shown) such as IOT are arranged in a vertical and horizontal manner (arranged in a lattice pattern) on a transparent substrate (transparent glass substrate). In the monitor 20, the operation surface of the touch operation unit is the operation display surface 20 </ b> A, and the display image of the display unit 22 is visible through the touch panel unit 24 from the operation display surface 20 </ b> A side.

  The touch panel unit 24 is applied with a capacitance method in which the touch operation position can be specified based on the capacitance between the vertical and horizontal electrodes that change when the operation surface (operation display surface 20A) is touched. . Note that the touch panel unit 24 is not limited to the capacitive method, and a resistive film method may be applied, and an infrared method may be applied when the touch panel unit 24 has a flat plate shape.

  As shown in FIGS. 2A and 2B, an inner mirror 26 is provided in the vehicle interior of the vehicle 12, and a monitor 20 is provided on the inner mirror 26. The inner mirror 26 includes a stand (stay) 28, and the stand 28 is attached to the ceiling surface of the vehicle front side of the passenger compartment and the central portion in the vehicle width direction. The monitor 20 is arranged such that the longitudinal direction is substantially horizontal and the display surface is directed to the rear side of the vehicle, and the longitudinal intermediate portion of the monitor 20 is supported by the lower end portion of the stand 28. For this reason, the monitor 20 is disposed at the center in the vehicle width direction and at the top of the front windshield glass, the operation display surface 20A is directed substantially rearward of the vehicle, and the display image is made visible to passengers in the vehicle interior. In addition, the occupant's touch operation is enabled.

  The monitor 20 can be rotated about the vertical axis (left and right direction) and can be rotated (tilted) about the horizontal axis (vertical direction). Therefore, the operation display surface 20A is directed to the vehicle right side (arrow R direction) and the vehicle left side (arrow L direction) when the monitor 20 is rotated in the left-right direction by applying a force greater than a predetermined force by the occupant. By rotating in the vertical direction, the operation display surface 20A is directed upward and downward.

  The monitor 20 may have a planar operation display surface 20A (the display surface of the display unit 22 and the operation surface of the touch panel unit 24). However, in the first embodiment, the monitor 20 has an operation display surface 20A that is a vehicle. The curved surface is convex toward the rear. Further, the monitor 20 is provided with a half mirror (wide mirror) (not shown), and the half mirror is disposed between the display unit 22 and the touch panel unit 24. For this reason, the monitor 20 functions as an inner monitor by displaying a photographed image of the camera 14 through the operation display surface 20A. Further, the monitor 20 is a vehicle interior rear-view mirror (inner mirror) in which the half mirror mirrors the rear view through the rear window glass and the door glass together with the vehicle interior when the display unit 22 is not displayed (the display unit 22 is off). Function.

  Therefore, as shown in FIG. 3, the monitor 20 is rotated so as to face the occupant seated in the driver's seat slightly from the rear side of the vehicle so that it can function as an inner mirror when the image is not displayed. The operation display surface 20A is tilted toward the driver's seat with respect to the rear of the vehicle. In FIG. 3, the monitor 20 with the operation display surface 20 </ b> A directed toward the rear of the vehicle is indicated by a solid line, and the monitor 20 with the operation display surface 20 </ b> A directed toward the occupant side (driver's seat side) is a broken line. Is shown.

  As shown in FIG. 1, the display control device 18 is provided with a drive circuit 30A to which the display unit 22 is connected, a drive circuit 30B to which the touch panel unit 24 is connected, and a display processing unit 32. In the display control device 18, drive circuits 30 </ b> A and 30 </ b> B and a camera 14 (rear camera 14 </ b> A and side cameras 14 </ b> L and 14 </ b> R) are connected to the display processing unit 32.

  The display processing unit 32 includes a microcomputer in which a CPU, a ROM, a RAM, a nonvolatile storage medium (for example, an EEPROM), and an I / O (input / output interface) are connected to a bus. Further, various programs such as a vehicle visual display control program are stored in the ROM or the like of the display processing unit 32, and the CPU reads the program stored in the ROM or the like and executes it while developing it in the RAM.

  The program stored in the display processing unit 32 includes drivers (software) for the display unit 22 and the touch panel unit 24, and the drive circuits 30A and 30B are operated by the driver, whereby the backlight in the display unit 22 is displayed. Lighting and image display are controlled, and a touch operation on the touch panel unit 24 is detected.

  The programs executed by the CPU of the display processing unit 32 include an image processing program, an operation screen setting program, an operation reception program, an area setting program, and an operation setting program. The display processing unit 32 executes an image processing program, an operation screen setting program, an operation reception program, an area setting program, and an operation setting program by the CPU, so that the image processing unit 34 and an operation screen setting unit 36 as a setting unit are executed. It functions as an operation receiving unit 38 as a receiving unit, an area setting unit 40 as a specifying unit, and an operation setting unit 42.

  The image processing unit 34 combines the captured images of the rear camera 14A and the side cameras 14L and 14R to generate a rear image displayed on the monitor 20 (display unit 22). Note that the monitor 20 is provided in front of the vehicle from the driver's seat, and the rear image displayed on the monitor 20 is horizontally reversed with respect to the captured image.

  The viewpoint position of image shooting differs between each of the rear camera 14A and the side cameras 14L and 14R. From here, the image processing unit 34 performs viewpoint conversion processing for aligning the viewpoint position with the captured images of the rear camera 14A and the side cameras 14L and 14R. In the viewpoint conversion process, a virtual viewpoint is set on the front side of the vehicle with respect to the center position of the monitor 20 and a virtual screen is set on the rear side of the vehicle, and the captured images of the rear camera 14A and the side cameras 14L and 14R are virtual viewpoints. From the viewpoint, the image is converted into an image projected on the virtual screen. On the monitor 20, the image projected on the virtual screen is developed and displayed.

  The virtual screen may be a flat surface, but is preferably a curved surface that is convex toward the rear of the vehicle. Note that, when performing the viewpoint conversion process, assuming that the same subject is reflected between different captured images, the same object is set to the same size in each captured image. In addition, the viewpoint conversion processing can be applied to any method for converting each captured image into an image projected on a virtual screen when viewed from a virtual viewpoint.

  In the image processing unit 34, along with the viewpoint conversion, the captured images of the rear camera 14 </ b> A, the side camera 14 </ b> L, and the side camera 14 </ b> R are trimmed according to the display area of the monitor 20, and the viewpoint converted and trimmed images Is synthesized. The imaging areas of the rear camera 14A and the side cameras 14L and 14R partially overlap. For this reason, in the trimming process, there are boundaries in the overlapping area between the captured image of the rear camera 14A and the captured image of the side camera 14L, and the overlapping area between the captured image of the rear camera 14A and the captured image of the side camera 14L. The position is set. The image processing unit 34 cuts out (trims) the captured image at the set boundary position, and combines the extracted captured images at the boundary position so that the captured images of the rear camera 14A and the side cameras 14L and 14R are obtained by one camera. The rear image is the same as that taken and displayed on the monitor 20.

  Further, in the image processing unit 34, when setting of processing such as enlargement / reduction of the image displayed on the monitor 20 by the occupant, change of the boundary position, movement of the display area (scrolling), etc. is changed, the changed setting is set. Based on this, processing such as enlargement / reduction of the image, change of the trimming area including change of the boundary position is performed.

  The operation setting unit 42 performs operation settings for the display unit 22 such as setting and change of processing executed in the image processing unit 34, and brightness of the display unit 22. The operation screen setting unit 36 sets a GUI (graphic user interface) as a screen for performing various settings in the operation setting unit 42. The GUI set in the operation screen setting unit 36 is input to the image processing unit 34 and is displayed on the monitor 20 so as to be superimposed on the rear image.

  The operation receiving unit 38 detects a touch operation on the operation display surface 20A (the operation surface of the touch panel unit 24) and specifies a touch operation position. In addition, the operation receiving unit 38 specifies and receives an occupant instruction from the touch operation position on the GUI, and outputs the received instruction to the operation setting unit 42. The operation setting unit 42 changes the settings for the display unit 22 and the image processing unit 34 based on the instruction received by the operation receiving unit 38.

  On the other hand, in the area setting unit 40, the entire operation display surface 20A of the monitor 20 (the operation surface of the touch panel unit 24) is divided into a plurality of divided areas 44. As shown in FIG. 3, in the first embodiment, the operation display surface 20A of the monitor 20 is divided into two vertically and horizontally, and four divided regions 44A, 44B, 44C, and 44D are set.

  Here, the area setting unit 40 designates one divided area 44 among the plurality of divided areas 44 (44A to 44D) of the operation display surface 20A. The operation screen setting unit 36 sets the divided area 44 specified by the area setting unit 40 as a touch operation area, and sets a GUI so that a touch operation is performed on the divided area 44. In other words, the operation screen setting unit 36 sets the GUI so that an icon or the like corresponding to an instruction option for operation is displayed in the divided region 44 specified by the region setting unit 40.

  The divided area 44 set as the touch operation area is preset based on the seating position (position of the steering wheel 12A of the vehicle 12) of the occupant (driver) with respect to the arrangement position of the monitor 20, and is stored in the storage medium (EEPROM). Has been. In the first embodiment, a divided region 44D is set and stored for the right-hand drive vehicle 12. The area setting unit 40 specifies the divided area 44D by reading the divided area 44D from the storage medium. As a result, the divided area 44D is set as a touch operation area.

  Next, as an operation of the first embodiment, a designation of the divided area 44 and a touch operation on the designated divided area 44 will be described.

  When the vehicle visual recognition device 10 is attached, it is known whether the vehicle 12 to be attached is the steering wheel 12A is a right-hand drive vehicle on the right side of the vehicle or the steering wheel 12A is a left-hand drive vehicle on the left side of the vehicle. Moreover, the monitor 20 is provided in the vehicle front side and the upper side of the passenger compartment. From here, prior to shipment of the vehicle 12 (when the vehicle visual recognition device 10 is attached to the vehicle 12), the divided area 44D on the right side and the lower side of the divided area 44A to 44D on the operation display surface 20A of the monitor 20 is displayed. (A region closest to the passenger seated in the driver's seat) is stored so as to be designated as the touch operation region. In addition, when the vehicle visual recognition device 10 is provided in the left-hand drive vehicle 12, the lower left divided area 44B is stored on the operation display surface of the monitor 20 so as to be designated as the touch operation area. .

  The vehicular visual recognition device 10 operates when an ignition switch (IG) (not shown) of the vehicle 12 is turned on and starts displaying an image on the monitor 20 (display unit 22). When the ignition switch is turned off, the monitor 20 is turned on. The image display is stopped and the operation ends.

  When the display processing unit 32 of the vehicle visual recognition device 10 starts operation, the display operation unit 32 sets a touch operation area as an initial setting. The touch operation area is designated by reading out the divided area 44 (44D) stored in advance so as to be designated as the touch operation area.

  On the other hand, in the vehicular visual recognition device 10, when the initial setting is completed, the captured images of the rear camera 14 </ b> A and the side cameras 14 </ b> L and 14 </ b> R are read, and viewpoint conversion processing, trimming processing, and composition processing are performed on the read captured images. A rear image of the vehicle 12 is generated, and the generated rear image is displayed on the monitor 20. As a result, the rear image displayed on the monitor 20 assists the occupant in viewing the rear of the vehicle.

  In the vehicular visual recognition device 10, when the setting change of the operation of the monitor 20 (display unit 22) and the setting change of the process for the rear image displayed on the monitor 20 are performed, the GUI set in the operation screen setting unit 36 is set. Is displayed on the monitor 20. At this time, the operation screen setting unit 36 sets the GUI so that the touch operation is performed on the divided area 44D designated as the touch operation area. When a touch operation is performed while the GUI is displayed on the monitor 20, the operation reception unit 38 receives an operation instruction corresponding to the touch operation position. FIGS. 4A and 4B show a GUI that uses the divided area 44D as a touch operation area. 4A and 4B show that the operation display surface of the monitor 20 is tilted to the right with respect to the rear of the vehicle.

  FIG. 4A shows a GUI 46 used for setting (setting change) of the brightness of the display unit 22 (brightness of the monitor 20). The GUI 46 includes a bar 48 indicating brightness. As an operation instruction option icon, an icon 50A for setting the standard brightness, an icon 50B for changing the brightness in a dark direction, and a direction in which the brightness is dark. An icon 50C to be changed is included. The GUI 46 is set so that the icons 50A to 50C are arranged in the divided area 44D.

  While the GUI 46 is displayed on the monitor 20, the occupant (driver) touches the monitor 20 (operation display surface) corresponding to any of the icons 50 </ b> A to 50 </ b> C with a finger, so that the touch operation position is operated. It is detected by the reception unit 38. As a result, an occupant's operation instruction is accepted, and the brightness of the monitor 20 is changed and the display of the bar 48 is changed corresponding to the touch-operated icon.

  FIG. 4B shows a GUI 52 that is used for an instruction to scroll the rear image displayed on the monitor 20. The GUI 52 includes icons 54U for instructing an up scroll, an icon 54D for instructing a down scroll, an icon 54L for instructing a left scroll, and an icon 54R instructing a right scroll as options icons. The GUI 52 is set so that the icons 54D, 54L, 54R, and 54U are arranged in the divided area 44D of the operation display surface 20A of the monitor 20.

  When the GUI 52 is displayed on the monitor 20, the occupant (driver) touches the operation display surface 20A of the monitor 20 corresponding to any of the icons 54D, 54L, 54R, and 54U with a finger, thereby touching The operation position is detected by the operation reception unit 38. Thereby, the rear image displayed on the monitor 20 is scrolled. The GUIs 46 and 52 are not displayed when a predetermined time (about several seconds) has passed in the non-touch state, and the setting ends. In the GUI 52, an icon for returning the displayed rear image to the reference position centered on the rear of the vehicle may be provided. In this case, the icon is returned to the standard position at the center position of the icons 54D, 54L, 54R, and 54U. An icon may be displayed.

  In the vehicular visual recognition device 10, the captured images of the rear camera 14 </ b> A and the side cameras 14 </ b> L and 14 </ b> R are trimmed at the boundary position, and the rear image obtained by combining the trimmed captured images is displayed on the monitor 20. For this reason, the divided area 44D includes the boundary position between the captured image of the rear camera 14A and the captured image of the side camera 14L. From here, when changing the boundary position, in the GUI (not shown) for changing the boundary position, a line indicating the boundary position is displayed in the divided region 44D, and the displayed line is touched in the vehicle width direction. Perform the slide operation to move. Thereby, the boundary position between the captured image of the rear camera 14A and the captured image of the side camera 14L is changed, and the rear camera 14A is similar to the boundary position between the captured image of the rear camera 14A and the captured image of the side camera 14L. The boundary position between the captured image and the captured image of the side camera 14R may be changed.

  Therefore, the division area 44D closest to the occupant among the division areas 44A to 44D is set as the designated touch operation area, so that the occupant seated in the driver's seat can easily perform a touch operation. Further, since the divided area 44D is close to the occupant's body on the operation display surface 20A of the monitor 20, by setting the divided area 44D as the touch operation area, the occupant can perform the touch operation with the right hand opposite to the monitor 20 as well. Can be touched more easily. In addition, since the lower divided area 44D of the monitor 20 is set as the touch operation area, it is possible to suppress the rear image displayed on the monitor 20 from becoming difficult to see with the finger (hand) of the passenger operating the touch.

  In addition, when the display unit 22 is not lit, the monitor 20 has the operation display surface 20A slightly directed toward the occupant side with respect to the vehicle rear so that the vehicle rear is reflected on the half mirror. For this reason, when the operation display surface 20A of the monitor 20 is a curved surface convex toward the rear of the vehicle, when the touch operation position is in an area on the left side of the monitor 20 (divided areas 44A, 44B, etc.), Thus, an error between the display position of the icon on the display unit 22 and the position where the icon can be seen on the monitor 20 (operation display surface 20A) becomes large, and an error is likely to occur in the touch operation.

  On the other hand, since the divided area 44D of the monitor 20 faces the occupant side, the shift between the icon display position on the display unit 22 and the position where the icon can be seen on the operation display surface 20A is reduced. Can be prevented from occurring, and erroneous operations that are recognized as instructions different from the passenger's intention can be suppressed.

  Since the touch operation on the monitor 20 (operation display surface 20A) becomes easy, the image displayed on the monitor 20 can be easily changed by the occupant, and the image displayed on the monitor 20 assists the occupant in viewing the rear of the vehicle. it can. Further, when the vehicular visual recognition device 10 is attached to a left-hand drive vehicle, it is only necessary to store the divided area 44B as the touch operation area, so that it is possible to store the monitor 20 without changing the hardware. A passenger's touch operation on the operation display surface 20A can be facilitated.

  In the first embodiment described above, the GUI is displayed on the monitor 20, but the instruction content may be set for each state of the touch operation.

  For example, in the first embodiment, it has been described that the display / non-display of the monitor 20 is switched by turning on / off the ignition switch. However, the present invention is not limited to this, and a touch operation (on the divided region 44D of the monitor 20 ( The display on the monitor 20 may be turned on / off by performing a long tap operation. In this case, by performing a touch operation (long tap operation) on the divided area 44D while the rear image is displayed on the monitor 20, the display unit 22 is turned off while maintaining the operation state of the touch panel unit 24. The display unit 22 may be turned on by performing a touch operation on the divided region 44D in the off state.

  Further, in a state where the rear image is displayed on the monitor 20, a slide operation for moving the touch position while performing a touch operation on the divided region 44D is performed so that the rear image is scrolled in the sliding direction of the touch operation. Also good. Furthermore, the display image is enlarged by a swipe operation that moves the two fingers away from the divided area 44D of the monitor 20 while touching the divided area 44D with two fingers, and the divided area 44D of the monitor 20 is touched with two fingers. The displayed image may be reduced by a pinch operation that moves the two fingers closer together while operating.

  In the first embodiment, the monitor 20 is provided on the inner mirror 26. However, the monitor 20 may be provided at the center in the vehicle width direction of the instrument panel on the front side of the vehicle. 20 may be fixed so as not to rotate in the left-right direction and the up-down direction.

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.

  FIG. 5 shows a visual device for vehicle 10A according to the second embodiment. The vehicle visual recognition device 10A is different from the vehicle visual recognition device 10 of the first embodiment in that a rotation detection unit 60 as a detection unit is provided on the monitor 20 (or the stand 28). The rotation detection unit 60 is connected to the region setting unit 40A, and the vehicle visual recognition device 10A is different from the vehicle visual recognition device 10 in that the region setting unit 40A is provided in place of the region setting unit 40. To do.

  The monitor 20 is attached to the stand 28 so as to be rotatable (turnable) with the operation display surface 20A directed toward the rear of the vehicle as a reference direction. The rotation detector 60 is rotated by a predetermined angle or more so that the monitor 20 is directed to the right side of the vehicle width (arrow R side) with respect to the reference direction, or the monitor 20 is left of the vehicle width with respect to the reference direction. It is detected whether or not it is rotated by a predetermined angle or more so as to face (arrow L side). As such a rotation detection unit 60, a switch that turns on when the monitor 20 is rotated by a predetermined angle or more in the arrow R direction using a mechanical switch such as a limit switch, and the monitor 20 is predetermined in the arrow L direction. You may provide the switch which turns on by rotating more than an angle.

  Further, as the rotation detection unit 60, using a gyro sensor that detects the rotation of the monitor 20, whether the monitor 20 is rotated in the direction of arrow R (right side of the vehicle width) by a predetermined angle or more while the vehicle 12 is stopped traveling, Alternatively, it may be detected that the monitor 20 is rotated by a predetermined angle or more in the arrow L direction (the vehicle width left side).

  When the rotation detection unit 60 detects that the monitor 20 is rotated in the left-right direction and the direction of the operation display surface 20A is changed, the region setting unit 40A performs a touch operation from the divided regions 44A to 44D based on the detection result. Set the area. At this time, if it is detected that the monitor 20 has been rotated to the right, the area setting unit 40A designates the divided area 44D as the touch operation area. In addition, when it is detected that the monitor 20 is rotated to the left side, the area setting unit 40A specifies the divided area 44B as the touch operation area.

  Next, as an operation of the second embodiment, setting of a touch operation area in the vehicle visual recognition device 10A will be described. FIG. 6 shows the flow of the touch operation area setting process.

  This flowchart starts when the vehicular visual recognition device 10A operates to display a rear image on the monitor 20, and ends when the operation of the monitor 20 (rear image display) is stopped. In the initial state where the operation of the monitor 20 is started, the previous setting when the display of the monitor 20 was stopped is applied. In the following description, in the initial setting, it is assumed that the monitor 20 is rotated to the right by a predetermined angle or more and the lower right divided area 44D of the monitor 20 is designated as the touch operation area.

  Here, in the first step 100, the rotation angle (orientation) of the monitor 20 detected by the rotation detector 60 is read, and in the next step 102, whether or not the rotation angle of the monitor 20 is equal to or greater than a predetermined angle. Confirm. At this time, if the rotation angle of the monitor 20 is equal to or greater than the predetermined angle, an affirmative determination is made in step 102 and the routine proceeds to step 104.

  In step 104, it is confirmed whether or not the orientation of the monitor 20 has been changed. That is, in step 102 and step 104, whether or not the monitor 20 that has been directed to the right side has been rotated to the left side to a predetermined angle or more (or the monitor 20 that has been directed to the left side has a predetermined angle or more to the right side). To check whether or not it has been rotated.

  Here, when the monitor 20 turned to the right side is rotated to the left side until the monitor 20 turned to a predetermined angle or more with respect to the rear of the vehicle, an affirmative determination is made in step 104 and the process proceeds to step 106. . In step 106, the lower left divided area 44B of the monitor 20 is designated, and the divided area 44B is set as a touch operation area. For this reason, the touch operation area is changed from the divided area 44D to the divided area 44B. When a negative determination is made in step 102 or step 104, the process proceeds to step 108, and the touch operation area is held in the previous divided area (divided area 44D).

  As a result, in the vehicular visual recognition device 10A, even if the touch operation area is not set in advance, an occupant attached to the right-hand drive vehicle and seated on the right seat (driver's seat) places the operation display surface 20A on the right side. By rotating the monitor 20 so as to be directed, the lower right divided area 44D of the monitor 20 is designated and set as the touch operation area. In addition, the vehicle visual device 10A is attached to the left-hand drive vehicle, and an occupant seated on the left seat (driver's seat) rotates the monitor 20 so that the operation display surface 20A is directed to the left side. Twenty lower left divided areas 44B are designated and set as touch operation areas.

  By setting the touch operation area in this way, an occupant's touch operation on the monitor 20 becomes easy. Further, even when the monitor 20 is curved in a convex shape toward the rear of the vehicle, the touch operation is easy.

  Further, in a right-hand drive vehicle, when the occupant in the left seat (passenger seat) temporarily turns the monitor 20 to the left in order to visually recognize the rear of the vehicle, the divided area 44B is designated and the touch operation area is designated. Set to For this reason, the touch operation of the passenger in the passenger seat who visually recognizes the image on the monitor 20 becomes easy. Furthermore, the divided area 44D that is easy to operate for the occupant seated in the driver's seat is designated and touched only by returning the orientation of the monitor 20 to the direction in which the occupant seated in the driver's seat is easy to see (return to the right). Set in the operation area. Therefore, the occupant's touch operation can be easily performed as in the first embodiment, without performing an operation for changing the touch operation area.

  In the first and second embodiments, the operation display surface 20A of the monitor 20 is divided into four parts in the vertical (vertical) and horizontal (left and right), but not limited to this, it is divided into two in the left and right (vehicle width direction). As a result, the touch operation area can be widened.

  In the first and second embodiments, three cameras 14 (rear camera 14A and side cameras 14L and 14R) are used as the imaging unit. However, the imaging unit is a single camera (rear camera 14A). May be used, or two or four or more of the imaging regions partially overlapping may be used. Furthermore, as the imaging unit, an indoor camera (inner camera) that is provided in the front part of the vehicle interior and that can capture the rear of the vehicle through the vehicle interior and rear window glass, etc. is provided, and the image captured by the inner camera is combined with the rear image May be displayed.
