Abstract
(EN) The present invention is provided with: a camera (10) mounted on a vehicle and provided with a lens (11); a lens cleaning device (100) for cleaning the lens in accordance with a predetermined leans cleaning process; an attachment state determination unit (38) for determining the attachment state including the attachment degree of foreign substances attached to the lens (11) on the basis of the pixel values of pixels contained in the acquired captured image; and a control unit (101) for controlling the supply timing of a cleaning solution on the basis of the determined attachment state of the foreign substances. The attachment state determination unit (38) determines that the attachment state of dirt on the lens (11) is a first state when the attachment degree of foreign substances is within a predetermined threshold value that is equal to or greater than a first attachment threshold value and that is less than a second attachment threshold value, and controls the lens cleaning device (100) to delay the supply timing of the cleaning solution when it was determined that the attachment state of dirt on the lens (11) is the first state.
(FR) La présente invention comporte : une caméra (10) montée sur un véhicule et comportant une lentille (11); un dispositif de nettoyage de lentille (100) pour nettoyer la lentille conformément à un processus de nettoyage de lentille prédéterminé; une unité de détermination d'état de fixation (38) pour déterminer l'état de fixation comprenant le degré de fixation de substances étrangères fixées à la lentille (11) sur la base des valeurs de pixel de pixels contenus dans l'image capturée acquise; et une unité de commande (101) pour commander la temporisation de fourniture d'une solution de nettoyage sur la base de l'état de fixation déterminé des substances étrangères. L'unité de détermination d'état de fixation (38) détermine que l'état de fixation de saletés sur la lentille (11) est un premier état lorsque le degré de fixation de substances étrangères est dans une valeur seuil prédéterminée qui est égale ou supérieure à une première valeur seuil de fixation et qui est inférieure à une seconde valeur seuil de fixation, et amène le dispositif de nettoyage de lentille (100) à retarder la temporisation de fourniture de la solution de nettoyage lorsqu'il a été déterminé que l'état de fixation de saletés sur la lentille (11) est le premier état.
(JA)  車両に搭載され、レンズ11を備えたカメラ10と、所定のレンズ洗浄工程に従いレンズを洗浄するレンズ洗浄装置100と、取得した撮像画像に含まれる画素の画素値に基づいて、レンズ11に付着した異物の付着度を含む付着状態を判断する付着状態判断部38と、判断された異物の付着状態に基づいて、洗浄液の供給タイミングを制御する制御部101と、を備え、付着状態判断部38は、異物の付着度が第1付着閾値以上かつ第2付着閾値未満の所定閾値内である場合にはレンズ11の汚れの付着の状態が第1状態であると判断し、レンズ11の汚れの付着の状態が第1状態であると判断された場合には、レンズ洗浄装置100に洗浄液の供給タイミングを遅延させる制御を行う。
