Provided is a device whereby the position of an obstacle can be perceived on a monitor without compromising the effectiveness of displaying an overhead image on the monitor. An overhead image generating unit generates an overhead image from images captured using a plurality of cameras, and the overhead image is displayed in an auxiliary display area (21B) of a monitor (21). When an obstacle detection part detects an obstacle (X) in proximity to a vehicle, a specified information output unit emphasizes the display of a frame (F2) in the outer side of a divided area (D2) of the overhead image that contains the obstacle (X). Touching the auxiliary display area (21B) with a finger or the like during this emphasized display causes the captured image of the obstacle (X) to be enlarged and displayed in the auxiliary display area (21B).
