PROBLEM TO BE SOLVED: To provide an imaging system that performs imaging while focusing on the eyes of the driver of a subject vehicle, and make it possible to accurately focus on the eyes of the driver of the subject vehicle.SOLUTION: An eyeball tracking device comprises: an adjustment part 113 that operates a pan-tilt mechanism 33 and a focus mechanism 32 to perform imaging while enlarging the eyes of a driver with a telescopic camera 30 on the basis of the positions of the eyes of the driver in a wide angle image acquired by a wide angle image acquisition part 101; a parallax specification part 105 that sequentially specifies the parallax between the wide angle image acquired by the wide angle image acquisition part 101 and a telescopic image acquired by a telescopic image acquisition part 102; and a pan-tilt correction part 111 that sequentially determines the amount of correction for the pan-tilt mechanism 33 according to a mechanism error of the pan-tilt mechanism 33 on the basis of the difference between a parallax when the pan-tilt mechanism 33 is assumed to have no mechanism error and the parallax specified by the parallax specification part 105. The adjustment part 113 operates the pan-tilt mechanism 33 according to the amount of correction sequentially determined by the pan-tilt correction part 111.SELECTED DRAWING: Figure 3

    【課題】自車のドライバの眼に焦点を合わせて撮像する撮像システムにおいて、自車のドライバの眼に精度よく焦点を合わせやすくすることを可能にする。【解決手段】広角画像取得部101で取得した広角画像中のドライバの眼の位置に基づいて、望遠カメラ30でドライバの眼を拡大して撮像するようにパンチルト機構33及びフォーカス機構32を動作させる調整部113と、広角画像取得部101で取得した広角画像と望遠画像取得部102で取得した望遠画像との視差を逐次特定する視差特定部105と、パンチルト機構33の機構誤差がないとした場合の視差と視差特定部105で特定した実際の視差とのずれをもとに、パンチルト機構33の機構誤差に応じたパンチルト機構33の補正量を逐次決定するパンチルト補正部111とを備え、調整部113は、パンチルト補正部111で逐次決定する補正量に従ってパンチルト機構33を動作させる。【選択図】図3
