IMAGE CONTROL SYSTEM

An image control system includes a rear camera, a left rear (right rear) camera, a display device, and an image control device for generating a combined image and displaying the combined image on the display device. The image control device identifies a rear target object and a left rear (right rear) target object which are closest to the vehicle in an own lane and a left lane (right lane), respectively, and changes a magnitude of the rear left-side (right-side) azimuth angle being an azimuth angle of a left (right) boundary line defining a horizontal angle of view of a rear effective range based on a combination of presence or absence of the rear target object and a level of closeness to this object and presence or absence of the left rear (right rear) target object and a level of closeness to this object.
