Summary: | To provide an image processing device capable of appropriately recovering the contrast of an image.SOLUTION: A camera 10 includes an imaging unit 20 that captures an image of the surroundings of a vehicle from the inside of a windshield of the vehicle. A hood is arranged below the imaging unit 20 so as to fit within the angle of view of the imaging unit 20. A control unit 30 includes an acquisition unit 31 that acquires a brightness parameter indicating the degree of brightness of the hood reflected in the image, a whitening amount calculation unit 32 that calculates the degree of whitening of an image caused by reflection of external light by the hood and the windshield as a whitening amount on the basis of the brightness parameter, and a correction unit 33 that performs contrast correction of the image on the basis of the whitening amount.SELECTED DRAWING: Figure 2
【課題】画像のコントラストを適正に回復させることのできる画像処置装置を提供する。【解決手段】カメラ10は、車両のウインドシールドの内側から車両の周囲を撮像する撮像部20を有している。撮像部20の画角内にフードが入るように撮像部20の下方にフードが配置されている。制御部30は、画像に映り込んだフードの明るさの度合を示す輝度パラメータを取得する取得部31と、輝度パラメータに基づいて、フード及びウインドシールドでの外光の反射により生じる画像の白浮きの度合を白浮き量として算出する白浮き量算出部32と、白浮き量に基づいて画像のコントラスト補正を実施する補正部33と、を備える。【選択図】 図2 |
