PERIPHERY MONITORING APPARATUS

A periphery monitoring apparatus includes: a detector configured to detect a roughness state of a road surface in a traveling direction of a vehicle; an acquisition unit configured to acquire a guide marker to be superimposed onto an image based on captured image data output from an imager that captures an image of a peripheral region including the traveling direction of the vehicle, the guide marker being displayed in a manner that follows a roughness state of the road surface in the traveling direction of the vehicle; and a controller configured to superimpose the guide marker onto the image in the display manner that follows the roughness state and display the image on a display device.
