Can be displayed.

  Here, how the display state of the display monitor 18 changes in accordance with the change in the driving state during the period from when the vehicle V is parked and stopped to when the vehicle V starts to park and parks at the parking lot (1) ) To (10) will be described sequentially. First, when the vehicle V is parked or stopped, four images “LS”, “RS”, “B”, and “NAVI” are displayed on the display monitor 18. (2) In a state where the vehicle V is traveling straight at a low speed of, for example, less than 20 km / h, “LS” and “RS” are displayed on both the left and right sides of the display monitor 18 with the center portion open. (3) When the vehicle V is traveling straight ahead at a high speed of, for example, 20 km / h or higher, the image “NAVI” is displayed on the entire screen of the display monitor 18.

  (4) When the vehicle V operates the turn signal 22 at a low speed of, for example, less than 20 km / h and turns to the left by operating the steering handle 24 while indicating the intention of turning left to enter the parking lot, for example, the center is left empty. “LS” and “RS” are displayed on both the left and right sides of the display monitor 18. (5) For example, when the vehicle V is traveling straight ahead at a low speed of, for example, less than 20 km / h in a parking lot, the center portion is vacated. “LS” and “RS” are displayed on both the left and right sides of the display monitor 18. (6) For example, the steering wheel 24 is operated without operating the turn signal 22 at a low speed of, for example, less than 20 km / h. In a state where the course is changed to turn right forward, the image “RS” is displayed on the right side of the display monitor 18 and the image “NAVI” is displayed on the lower side of the remaining screen. (7) For example, parking In the state where the vehicle V changes the course so as to turn leftward by operating the steering handle 24 without operating the turn signal 22 at a low speed of, for example, less than 20 km / h, an image “LS” is displayed on the left side of the display monitor 18. Is displayed and the image “NAVI” is displayed on the lower side of the remaining screen.

  Further, (8) When the vehicle V travels straight backward at a low speed of, for example, less than 20 km / h in a parking lot, “LS” and “RS” are displayed on both the left and right sides of the display monitor 18 with the center portion open, 9) When the vehicle V changes its course to turn leftward by operating the steering handle 24 at a low speed of less than 20 km / h, for example, the image “LS” is displayed on the left side of the display monitor 18 and the remaining screen The image “B” is displayed on the lower side, and further, from the state of (8) above, (10) the vehicle V takes a course to turn right rearward by operating the steering handle 24 at a low speed of, for example, less than 20 km / h. When changing, the image “RS” is displayed on the right side of the display monitor 18 and the image “B” is displayed below the remaining screen.

  That is, when the vehicle travels at a high speed of, for example, 20 km / h or more, the image processing unit 17 displays both the image “LS” based on the image captured by the left image capturing unit 14L and the image “RS” based on the image captured by the right image capturing unit 14R. 18, but when the vehicle is traveling at a low speed of, for example, less than 20 km / h, one of the images “LS” and “RS” is displayed on the display monitor 18. When the course is changed by operating the steering handle 24 without operating the winker 22, the course change side image is selected from the images “LS” and “RS” and displayed on the display monitor 18.

  By the way, the vehicle driver sitting in the driver's seat in the passenger compartment can directly view the front side through the windshield 27, and the direct field of view of the vehicle V from the eye point EP of the vehicle driver in FIG. This is a region DA1 that is ahead of the line of sight EL1 that extends forward through the upper surface of the bonnet 28, and is indicated by a plurality of oblique lines that descend to the right in FIG. Further, the vehicle driver can indirectly visually recognize the rear of both sides of the vehicle V by the left and right door mirrors 12L and 12R. In FIG. 1, the vehicle driver reflects from the eyepoint EP of the vehicle driver by the left door mirror 12L. This is an area IA that is behind the line of sight EL2 that extends rearward and that is indicated by a plurality of diagonal lines that descend to the right in FIG. Further, an area DA2 indicated by a plurality of slanting lines in the lower right in FIG. 2 is an area of direct field of view that can be directly seen by the vehicle driver through the window of the left front door 11L. It is an area relatively far to the side, and is an area not directly related to the device of the present invention for assisting the visual field near the side of the vehicle V.

  Thus, the left imaging means 14L attached to the housing 13L of the left door mirror 12L is provided with the left front mirror 12L and the left front mirror 12L on the front side of the vehicle V in front and behind the vehicle V. In order to prevent a blind spot from occurring between the indirect visual field area IA on the rear side, an area PA (including a portion of the direct visual field area DA1 and the indirect visual field area IA, which is continuous in the front-rear direction (lower left in FIG. 2). The right imaging means 14R that can be simultaneously imaged (a plurality of hatched areas) and is attached to the housing 13R of the right door mirror 12R is located on the right front side by the vehicle driver on the driver's seat, like the left imaging means 14L. Simultaneously include a direct view area and a continuous area in the front and rear, including a part of the indirect view area on the right rear side by the right door mirror 12R. It is possible to imaging.

  The image processing means 17 displays a captured image of an area MA where at least the front and rear boundaries of the imaging areas PA by the imaging means 14L and 14R overlap the rear edge of the direct visual field area DA1 and the front edge of the indirect visual field area IA. For example, in the imaging area by the left imaging means 14L, that is, the area PA, including the front overlapping area PA1 that overlaps the direct visual field area DA1 and the rear overlapping area PA2 that overlaps the indirect visual field area IA The imaging signal from the left imaging means 14L is processed so that the continuous area MA is displayed on the display monitor 18.

  By the way, the point where the optical axis RA of the left imaging means 14L intersects the road surface when the vehicle V is viewed from the side is the overlap region on the front side that directly overlaps the visual field region DA1 in the region MA displayed on the display monitor 18. Of the imaging area PA and the overlapping area PA2 on the rear side that overlaps the indirect field of view IA, the longitudinal direction on the vertical plane that passes through the center of the lens provided in the left imaging means 14L and is parallel to the longitudinal direction of the vehicle V It is set according to the distance. That is, when the front and rear overlap areas PA1 and PA2 have the same longitudinal distance on the vertical plane, the same point as the bisector of the area MA displayed on the display monitor 18 on the vertical plane. When the optical axis RA is set so as to intersect the road surface, and the front-rear direction distance of the front overlap area PA1 is larger than the front-rear direction distance of the rear overlap area PA2, the area MA displayed on the display monitor 18 is displayed. The optical axis RA is set so that the bisector on the vertical plane intersects the road surface in front of the point where the bisector intersects the road surface, and the longitudinal distance of the overlapping region PA2 on the rear side is equal to that of the overlapping region PA1 on the front side. When the distance is greater than the longitudinal distance, the optical axis RA is such that the bisector on the vertical plane of the area MA displayed on the display monitor 18 intersects the road surface behind the point where the road surface intersects. It is constant.

  The point where the optical axis of the right imaging means 14R intersects the road surface when the vehicle V is viewed from the side is set similarly to the optical axis RA of the left imaging means 14L.

  According to such image processing of the image processing unit 17, in the state where the images “LS” and “RS” are displayed on the left and right of the display monitor 18, the image based on the imaging of the left imaging unit 14L and the imaging of the right imaging unit 14R are displayed. 7 is displayed on the display monitor 18 as shown in FIG. 7, and this display image includes not only the left and right sides of the vehicle body but also the front and rear wheels, respectively.

  Moreover, the image processing means 17 is arranged on the display monitor 18 with lines indicating the left and right ends of the vehicle, a line of 0.4 m from the left and right ends of the vehicle, and 0 from the left and right ends of the vehicle, for example. .8 m line, the characters “BODY” indicating the side edge of the vehicle, and the characters “0.4” and “0.8” indicating the distance of the line from the side edge of the vehicle in the image. Superimposing processing can be executed in a superimposed manner, and the lines are displayed in different colors so that they can be clearly recognized.

  Further, the display monitor 18 is provided with a touch panel. In this touch panel, for example, an image displayed based on the imaging of the left imaging means 14L expands the left front area A ′ of the vehicle as shown in FIG. The vehicle is divided into an upper instruction area A for display and a lower instruction area B for expanding and displaying a left rear area B ′ of the vehicle that partially overlaps the left front area A ′ of the vehicle. The image processing means 17 enlarges either the left front area A ′ or the left rear area B ′ by instructing one of the upper instruction area A and the lower instruction area B with a finger. Displayed on the display monitor 18. For example, when an occupant of the vehicle V indicates the upper instruction area A with a finger, the image processing means 17 displays an enlarged image of the left front area A ′ on the display monitor 18 as shown in FIG. It will be.

  Next, the operation of the first embodiment will be described. The left and right imaging means 14L and 14R are arranged so that the vehicle driver on the driver's seat has the front direct view area DA1 and the rear indirect view area by the door mirrors 12L and 12R. An area PA that includes a part of IA and that is continuous in the front and back can be imaged at the same time, and is attached to the lower part of the housings 13L and 13R in the door mirrors 12L and 12R, and processes the imaging signals by the imaging means 14L and 14R.
