  First, in step S <b> 1, the control circuit 110 captures the periphery of the vehicle with the imaging device 130 and displays a landmark image M on the display panel 161 together with the captured image. The control circuit 110 images the periphery of the vehicle at predetermined intervals in the order of the front camera 131, the rear camera 132, the left side camera 133, and the right side camera 134. The control circuit 110 converts the captured image signals output from the cameras (131 to 134) into image signals that can be displayed on the display unit 160, and outputs the image signals to the display unit 160, thereby displaying the display panel. A captured image display unit 162 is set to 161 to display a captured image. Furthermore, the control circuit 110 displays a mark image M related to the host vehicle when displaying the captured image on the display panel 161. When displaying the captured image and the landmark image M, in order to make the positional relationship between the host vehicle and the captured image displayed on the display unit 160 easy to understand, the captured image is captured at a position corresponding to the imaging direction with the landmark image M as a reference. The image display unit 162 is set and a captured image is displayed.

  Specifically, as shown in FIG. 3A, a speedometer display unit 163 is used as an analog meter display unit that displays an image of a detection value of the state detection unit 120 at a predetermined position of the display panel 161 according to a change in the pointer. , A tachometer display unit 164, a fuel meter display unit 165, and a water temperature meter display unit 166. When the front camera 131 captures the front of the vehicle, the captured image display unit 162 is set in front of the mark image M (upward on the paper surface) to display the captured image. When the rear camera 132 captures the rear of the vehicle, as shown in FIG. 3B, the captured image display unit 162 is set behind the landmark image M (downward on the paper surface) to display the captured image. .

  Furthermore, when the left side camera 133 is imaging the left side of the vehicle, the captured image display unit 162 is set on the left side of the landmark image M and the captured image is displayed as shown in FIG. When the right side camera 134 is capturing the right side of the vehicle, the captured image display unit 162 is set on the right side of the landmark image M and the captured image is displayed as shown in FIG. Therefore, when the ignition SW 200 is turned on, the front and rear, left and right captured images and landmark images of the vehicle at predetermined intervals in the order of FIGS. 3A, 3B, 4A, and 4B. M is displayed on the display panel 161.

  3A, 3B and 4A, 4B, an image showing the upper surface of the vehicle is used as the mark image M. The mark image M is a driver as shown in FIG. It is good also as an image according to the viewpoint. That is, it is an image that enters the field of view when the driver is seated in the driver's seat and faces the front, and includes an image of the windshield, side mirror, rearview mirror, steering wheel, instrument panel, and the like.

3A, 3B, and 4A, 4B, the display position of the mark image M is aligned in the front-rear and left-right directions (up, down, left and right in the drawing) in accordance with the display position of the captured image display unit 162. Although described using the example of movement, the display position of the mark image M may be moved only in the front-rear direction (up and down direction on the paper surface). In this case, when the front camera 131 is imaging the front of the vehicle, the display position of the mark image M is moved backward (downward on the page) as shown in FIG.
When the rear camera 132 images the front of the vehicle, the display position of the mark image M is moved forward (upward in the drawing) as shown in FIG. 6B. When the front side of the vehicle is imaged by the left side camera 133 and the right side camera 134, the display position of the landmark image M is fixed as shown in FIG.

Also called.

  In step S <b> 2, the control circuit 110 detects the vehicle speed by the vehicle speed sensor 121. This is to determine whether or not to display the blind spot confirmation image described above. The display of the picked-up image and the mark image M shown in the above-described blind spot confirmation image is the presence or absence of an obstacle in front of the vehicle when the host vehicle is departed, when the vehicle is brought close to the left end of the road, or when traveling on a narrow road This is to inform the driver of blind spots from the driver, such as the presence or absence of a gutter at the end of the road, the level difference on the shoulder of the road, and the situation behind the vehicle when parking and stopping. In such a situation, the host vehicle is in a stopped state or in a slow state (for example, 5 km / h). Therefore, it is possible to determine whether or not to display the blind spot confirmation image by detecting the vehicle speed.

  In step S3, the control circuit 110 determines whether or not the vehicle speed detected in step S2 is within a predetermined vehicle speed. Then, if it is determined that the detected vehicle speed is not within the predetermined vehicle speed, the control circuit 110 regards that the blind spot confirmation image is not displayed and proceeds to step S4, and that the detected vehicle speed is within the predetermined vehicle speed. If it is determined, it is assumed that the blind spot confirmation image is being displayed, and the process returns to step S1.

  In step S4, the control circuit 110 stops outputting the captured image signals from the front camera 131, the rear camera 132, the left side camera 133, and the right side camera 134, and turns off the display of the blind spot confirmation image of the multi display unit. . In this case, the control circuit 110 may display a guidance route, a shift range image, and the like by a navigation device (not shown) on the multi display unit.

  In step S5, when an approaching vehicle exists, the control circuit 110 detects an approaching vehicle to the host vehicle in order to alert the driver of the host vehicle. The control circuit 110 sequentially stores images captured by the front camera 131 and the rear camera 132 in a RAM or the like, and calculates the movement amount of the same object in two images obtained around the predetermined time Δt from the stored images. An approaching vehicle is detected using an optical flow (motion vector) method that performs processing such as detection.

  In step S6, the control circuit 110 determines the presence or absence of an approaching vehicle based on whether or not there is a vehicle whose distance from the host vehicle is within a predetermined distance based on the detection result in step S5. If it is determined that it is necessary to call attention, the process proceeds to step S7. When it is determined that there is no approaching vehicle, it is considered that alerting is not necessary, and the process proceeds to step S8.

  In step S7, the control circuit 110 displays an image including the approaching vehicle detected in step S5 (hereinafter also referred to as an approaching vehicle image) on the display panel 161 together with the landmark image M. The control circuit 110 converts a captured image signal output from the front camera 131 or the rear camera 132 into an image signal that can be displayed on the display unit 160, and outputs the image signal to the display unit 160, whereby the display panel 161. The captured image display unit 162 is set in the multi display unit and the approaching vehicle image is displayed.

The unit 162 is set and a captured image is displayed. When the host vehicle is in a stopped state or in a state other than a slow speed (for example, 5 km / h), the landmark image M is an image in accordance with the driver's viewpoint, that is, the driver is seated in the driver's seat. Then, it is better to make the image enter the field of view when facing the front.

  Specifically, as shown in FIG. 7A, a speedometer display unit 163 is used as an analog meter display unit that displays an image of a detection value of the state detection unit 120 at a predetermined position of the display panel 161 according to a change in the pointer. , A tachometer display unit 164, a fuel meter display unit 165, and a water temperature meter display unit 166. When a vehicle is present within a predetermined distance in front of the host vehicle, the captured image display unit 162 is set at a position corresponding to the windshield of the landmark image M, and the approaching vehicle image captured by the front camera 131 is displayed. To do.

  Further, when a vehicle is present within a predetermined distance behind the same lane of the host vehicle, as shown in FIG. 7B, a captured image display unit 162 is set behind the landmark image M (downward on the paper surface). An approaching vehicle image including a vehicle approaching from behind the same lane imaged by the camera 132 is displayed.

  Further, when a vehicle is present within a predetermined distance behind the left lane of the host vehicle, a captured image display unit 162 is set on the left side of the landmark image M as shown in FIG. The approaching vehicle image including the vehicle approaching from the rear of the left lane of the subject vehicle is displayed. Further, when a vehicle is present within a predetermined distance behind the right lane of the host vehicle, a captured image display unit 162 is set on the right side of the landmark image M as shown in FIG. The approaching vehicle image including the vehicle approaching from the rear of the right lane of the subject vehicle is displayed.

  In step S8, the control circuit 110 stops outputting the captured image signals from the front camera 131, the rear camera 132, the left side camera 133, and the right side camera 134, and turns off the display of the approach display image of the multi display unit. . In this case, the control circuit 110 may display a guidance route, a shift range image, and the like by a navigation device (not shown) on the multi display unit. Further, when the guide route and the shift range image are displayed before the approach display image is displayed, the image may be displayed.

  When there is a vehicle within a predetermined distance behind the same lane of the host vehicle, behind the left lane, and behind the right lane, the rear view mirror and the side mirror included in the landmark image M should be used to call attention. Also good. For example, when there is an approaching vehicle behind the same lane, alerting is performed by changing the display mode of the rearview mirror, such as changing the color of the rearview mirror, turning on the rearview mirror, or blinking the rearview mirror. And if there is an approaching vehicle on the left or right lane of your vehicle, change the display mode of the side mirror, such as changing the color of the existing side mirror, turning on the side mirror, or flashing the side mirror. Call attention.

  Further, when a vehicle exists within a predetermined distance behind the same lane of the host vehicle, the approaching vehicle image may be displayed at the position of the rearview mirror included in the landmark image M. Further, when a vehicle is present within a predetermined distance behind the left lane and the right lane of the host vehicle, the approaching vehicle image may be displayed at the position of the side mirror included in the landmark image M.
