However, since the mounting position and the mounting angle of the image pickup camera 3 may change, the relative positional relationship between the left image 5L and the right image 5R displayed on the monitor is deviated. There was a risk that it would be uncomfortable. That is, it is difficult to completely fix the position and the angle of the image pickup camera 3, and the position or the angle of the image pickup camera 3 may move although it is a little, so that the regions picked up by the left and right image pickup cameras 3 are captured. Changes, and the positions of the left image 5a and the right image 5b on the screen 6 of the monitor change.

For example, when the right imaging camera 3 faces slightly below a predetermined value, the vehicle (right image 5R) displayed on the right side of the screen 6 shifts to the upper side as shown in FIG. Therefore, a shift H in the height direction occurs between the left image 5L and the right image 5R. The present invention has been made in view of this problem, and provides a vehicle monitoring device capable of easily adjusting the relative display positions of the right side image and the left side image.
