A multi-line camera such as a two-line camera acquires image data of an object moving relative to the camera. An output of a first sensor line is connected through a first time-delay memory to a first comparator, and is connected directly to a second comparator. An output of a second sensor line is connected directly to the first comparator, and is connected through a second time-delay memory to the second comparator. Thus, the current image data of each sensor line is respectively compared crosswise to the time-delayed previous image data of the respective other sensor line. An evaluation unit compares the outputs of the two comparators, to determine which comparison had a better degree of correspondence, and dependent thereon determines the direction of relative motion of the object relative to the camera.

Method and apparatus for automatic recognition of the relative motion direction of an object relative to a multiline camera

A method for controlling an electronic line-scan camera having at least two lines with light-sensitive pixels by means of external trigger signals. A predetermined number of lines of the sensor are exposed due to a first external trigger signal and the image information of the first exposed line and that of the subsequent line or lines are each output successively.
