PROBLEM TO BE SOLVED: To provide a video display device for a vehicle capable of, when generating an overlooking video of an own vehicle to be displayed at a display part on the basis of a photographic image of an on-vehicle camera, reducing a distortion appearing in the overlooking video due to a change in a vehicle attitude, and providing road surface information appropriate for a driver.SOLUTION: A video display device 10 for a vehicle comprises: an on-vehicle camera 20 for photographing a road surface around an own vehicle; a control part 40 for generating an overlooking video subjected to viewpoint conversion processing on the basis of image data captured by the on-vehicle camera, and for causing a display part 50 installed in a cabin to display the overlooking video; and a vehicle attitude sensor 30 for detecting a vehicle attitude. The control part has a platform specifying the vehicle attitude as a reference, and when there exists a deviation between a reference vehicle attitude specified by the platform and the vehicle attitude detected by the vehicle attitude sensor, performs correction processing based on a deviation amount Δ of the vehicle attitudes to the image data obtained by the on-vehicle camera to generate the overlooking video.SELECTED DRAWING: Figure 1

    【課題】車載カメラの撮像画像に基づいて自車両の俯瞰映像を生成して表示部に表示させる際に、車両姿勢の変化に起因して俯瞰映像に表れる歪みを低減し、運転者に適切な路面情報を提供することが可能な車両用映像表示装置を提供すること。【解決手段】自車両周辺の路面を撮影する車載カメラ20と、前記車載カメラが撮像した画像データに基づいて視点変換処理を行った俯瞰映像を生成し、車室内に設置された表示部50に表示させる制御部40と、車両姿勢を検知する車両姿勢センサ30と、を備えた車両用映像表示装置10において、前記制御部は、基準となる車両姿勢を規定したプラットフォームを有し、該プラットフォームで規定した基準車両姿勢と、前記車両姿勢センサが検知した車両姿勢との間にズレがある場合に、前記車載カメラにて得た画像データに対して車両姿勢のズレ量Δに基づく補正処理を行って前記賦形映像を生成する。【選択図】図1
