To allow for display of a video of an appropriate display region, regardless of an inclination angle of a vehicle.SOLUTION: A video processing apparatus for a vehicle includes: a video data acquisition part 341 for acquiring video data captured by a camera unit 10; a distortion correction part 343 for correcting distortion of the video data by using distortion parameters, and outputting distortion correction video data; an inclination angle detector 33 for detecting an inclination angle of a vehicle; a road surface region detector 342 for detecting a road surface region shown on the video data; and a determination part 35 for determining whether or not the inclination angle of the vehicle is equal to or more than a threshold and the area of the road surface region has changed more than the threshold, on the basis of the inclination angle of the vehicle detected by the inclination angle detector 33 and the road surface region detected by the road surface region detector 342. When the determination part 35 determines that the inclination angle of the vehicle is equal to or more than the threshold and the area of the road surface region has changed more than the threshold, the distortion correction part 343 corrects distortion by changing the distortion parameters according to change of the area of the road surface region.SELECTED DRAWING: Figure 1
【課題】車両の傾斜角によらず、適切な表示領域の映像を表示可能にする。【解決手段】カメラユニット10が撮影した映像データを取得する映像データ取得部341と、映像データの歪みを歪パラメータを用いて補正して、歪補正映像データを出力する歪補正部343と、車両の傾斜角を検出する傾斜角検出部33と、映像データに写されている路面領域を検出する路面領域検出部342と、傾斜角検出部33が検出した車両の傾斜角と、路面領域検出部342が検出した路面領域とに基づいて、車両の傾斜角が閾値以上であり、路面領域の面積が閾値以上、変化したか否かを判定する判定部35とを備え、歪補正部343は、判定部35が、車両の傾斜角が閾値以上であり、路面領域の面積が閾値以上、変化したと判定する場合、路面領域の面積の変化に応じて、歪パラメータを変更して歪みを補正する。【選択図】図1
