  In the display device 101 as well, as in the modification of the display device 1 shown in FIG. 7, the division ratio of the display area of each display unit can be made variable based on the steering angle and speed of the vehicle.

  For example, when making a right turn or changing the course to the right lane, the first display unit 130 moves up the boundary between the display area 130a (see FIG. 14) and the display area 130b (see FIG. 14) based on the steering angle of the vehicle. The display area 130b on which the captured image of the rear side of the vehicle is displayed may be relatively enlarged. In addition, as shown in FIG. 20, the display area 131a and the display area 131c in the second display unit 131 The boundary BH between the display area 131b and the display area 131d may be moved upward so that the display area 131b in which the rear captured image is displayed is larger than the display area 131c in which the front captured image is displayed. Further, the boundary BV between the display area 131a and the display area 131b and the display area 131c and the display area 131d may be moved to the left to further increase the display area 131b in which the rear captured image is displayed.

  Similarly, for example, when turning to the left or changing the course to the left lane, the boundary BH is moved upward in the second display portion 131 based on the steering angle of the vehicle, and the rear side of the passenger side (left side) Display area 131b in which the captured image is displayed is larger than display area 131a in which the captured image in the front of the vehicle is displayed, and display area 131d in which the captured image in the rear is displayed is a display in which the captured image in the front is displayed What is necessary is just to make it larger than the area | region 131c.

  For example, when the vehicle starts, the boundary BH is moved downward on the second display unit 131 based on the vehicle speed, and the rear captured image is displayed in the display area 131c where the front captured image is displayed. The display area 131d may be larger. Further, the boundary BV may be moved to the left to further enlarge the display area 131c in which the front captured image is displayed.

  Furthermore, as shown in FIG. 21, the boundary BH is divided into BHa and BHb at the intersection O between the boundary BH and the boundary BV at a standard division ratio set as appropriate, and the intersection O is the boundary. The boundary BV may be divided into BVa and BVb, and these boundaries BHa, BHb, BVa, and BVb may be moved independently. For example, when moving forward, as shown in FIG. 21, only the boundary BHb of the boundaries BHa and BHb is moved downward, and only the boundary BVa of the boundaries BVa and BVb is moved to the left, and the front captured image is displayed. The display area 131c may be enlarged. Further, during backward travel, only the boundary BHb of the boundaries BHa and BHb is moved upward, and only the boundary BVb of the boundaries BVa and BVb is moved to the left to enlarge the display area 131d on which the rear captured image is displayed. You may do it.
