카메라(3)의 초점 조정을 위해, 제 1 이미지는 제 1 프레임 기간(F1) 동안 캡처되며, 여기서 센서 어레이(11)의 복수의 행(P)은 롤링 셔터 모드에 따라 노출되고, 제 2 이미지는 제 1 프레임 기간(F1) 이후에 캡처된다. 관심 영역(6a, 6b, 6c, 7a, 7b, 7c)에 대응하는 센서 어레이(11) 상의 영역이 결정되고, 복수의 행(P)의 서브세트(P1)가 결정되고, 서브세트(P1)는 영역을 포함하며, 제 1 서브세트(P1)의 모든 행이 노출된 때 또는 그 이후에 시작하는 초점 조정 기간(Ta)이 결정된다. 적어도 하나의 초점 매개변수는 사전정의된 초점 설정에 따라 초점 조정 기간(Ta) 동안 조정된다.

    For focal adjustment of a camera (3), a first image is captured during a first frame period (F1), wherein a plurality of rows (P) of a sensor array (11) is exposed according to a rolling shutter mode, and a second image is captured after the first frame period (F1). An area on the sensor array (11) is determined, which corresponds to a region of interest (6a, 6b, 6c, 7a, 7b, 7c), a subset (P1) of the plurality of rows (P) is determined, which contains the area, a focal adjustment period (Ta) is determined, which starts when or after all rows of the subset (P1) have been exposed. At least one focal parameter is adjusted during the focal adjustment period (Ta) according to a predefined focal setting.
